Analysis of the structural characteristics and operating principles of horizontal injection molding machines

As one of the most common equipment in plastic processing, injection molding machines are widely used in many industries such as automobiles, home appliances, electronics, and packaging. Horizontal injection molding machines are a common type of injection molding equipment, which has certain advantages in structural design, operational stability, and production efficiency.

Basic structure of horizontal injection molding machine

Horizontal injection molding machines are mainly composed of five parts: injection system, clamping system, hydraulic system, electronic control system, and heating system. Each system has a clear function and cooperates with each other to ensure the smooth progress of the injection molding process.

1. Injection system

The injection system is the core part of the horizontal injection molding machine, responsible for injecting molten plastic into the mold. It is mainly composed of injection unit, heating coil, barrel, screw and other components. The injection system heats and melts the plastic material in the barrel through the rotation of the screw, and injects it into the mold through the nozzle under a certain pressure.

Screw: Responsible for melting the plastic raw materials in the barrel and conveying them to the mold cavity. The design of the screw determines the melting efficiency of the injection molding machine and the flow performance of the plastic.

Heating ring: used to heat the plastic raw material in the barrel to ensure that the raw material is in a molten state during injection.

Barrel and nozzle: The plastic in the barrel melts under the action of the heating ring and is injected into the mold through the nozzle.

2. Clamping system

The clamping system is mainly used to fix the injection mold and ensure the stability of the mold during the injection process through the clamping force. The clamping part of the horizontal injection molding machine includes a clamping device, a mold support plate, a slider and other structures.

Clamping device: driven by the hydraulic system, the mold is tightly closed to ensure the sealing during the injection process and prevent the plastic from leaking.

Mold support plate: bears the mold and ensures its stability.

Sliders and guide devices: help the opening and closing and positioning of the mold to ensure the accuracy of the mold.

3. Hydraulic system

The hydraulic system is the drive system of the horizontal injection molding machine, responsible for providing power for the injection and clamping systems. The hydraulic system is mainly composed of a hydraulic oil pump, a hydraulic cylinder, a valve, etc.

Hydraulic oil pump: provides power for the hydraulic system to drive the various movements of the injection and clamping parts.

Hydraulic cylinder: controls the movement of the injection system and the clamping system, and completes the screw rotation, mold locking and other operations through the push of the hydraulic cylinder.

4. Electronic control system

The electronic control system is the brain of the horizontal injection molding machine, responsible for the coordinated control of various parts of the machine to ensure the stable and precise operation of the machine. The electronic control system includes PLC controller, touch screen, sensor, button, etc.

PLC controller: controls various operations of the injection molding process, such as heating temperature, injection pressure, screw speed, etc.

Sensor and feedback system: monitors the working status of the machine in real time and feeds back to the PLC system to ensure precise control during the injection molding process.

5. Heating system

The heating system is responsible for heating the plastic to a molten state. The heating system is usually composed of an electric heating coil and a temperature control system. The fluidity and quality of the plastic are ensured by precise control of the temperature.

Working principle of horizontal injection molding machine

The working process of the horizontal injection molding machine includes four main steps: injection, pressure holding, cooling and demolding. Each step is crucial to ensure the quality and production efficiency of the injection molded parts.

1. Injection process

During the injection process, solid plastic particles are first placed in the hopper, and the plastic raw materials enter the heated barrel and gradually melt through the screw push. The heating system heats the barrel through the heating ring to maintain the fluidity of the plastic. Under appropriate pressure, the molten plastic is injected into the mold and the mold filling begins.

2. Holding pressure process

After the injection is completed, the injection pressure is maintained to ensure that the plastic in the mold is full and prevent the plastic from producing cavities in the mold. At this time, the screw will continue to maintain a certain pressure to keep the plastic inside the mold at a constant pressure.

3. Cooling process

During the holding pressure process, the cooling system starts to work, and the temperature of the mold is reduced by means of water cooling pipes, etc., so that the plastic in the mold solidifies. The length of the cooling time directly affects the quality and production efficiency of the injection molded parts.

4. Demolding process

When the plastic part is completely cooled and solidified, the mold begins to open, and the injection molded part is pushed out and demolded. At this time, the horizontal injection molding machine completes the demolding process of the mold through the mechanical structure or hydraulic system of the mold opening and closing. After demolding, the injection molded part is taken out and sent to the next process.

From energy consumption to efficiency: key factors in evaluating the performance of horizontal injection molding machines

Basic structure and operation principle of horizontal injection molding machine

1. Basic structure of injection molding machine

The horizontal injection molding machine consists of five major systems: injection system, mold system, hydraulic system, electronic control system and heating system. Each system has different functions and effects, and they work together to ensure the smooth progress of the injection molding process.

Injection system: The plastic raw material is heated and melted through the screw and injected into the mold through the nozzle.

Mold system: Responsible for molding the molten plastic into the required product. The design of the mold directly affects the accuracy of the product.

Hydraulic system: Provides clamping force and injection force to ensure that the mold does not deform during the injection molding process.

Electronic control system: Controls all injection molding process parameters, such as injection speed, injection pressure, temperature, etc.

Heating system: Heats the plastic raw material to a temperature suitable for injection to ensure the fluidity of the molten plastic.

2. Working principle of injection molding machine

The working principle of the horizontal injection molding machine is relatively simple. First, the plastic particles are heated to a molten state through the screw, and then the screw pushes the molten plastic into the mold under the action of the hydraulic system. The mold fixes the molten plastic into a solid state during the cooling process, and finally obtains a molded product. The various performances of the injection molding machine need to be precisely coordinated to ensure the dimensional accuracy and production efficiency of the product. 

Key evaluation indicators of energy efficiency of horizontal injection molding machines

1. Energy consumption

Energy consumption is one of the most critical indicators for evaluating the performance of horizontal injection molding machines. With the continuous improvement of environmental protection requirements and the rise in production costs, energy saving and consumption reduction have become important goals in the design and operation of injection molding machines. Energy consumption is usually determined by the following factors:

Injection pressure and speed: The pressure and speed during the injection molding process directly affect energy consumption. Higher injection pressure and too fast injection speed will lead to greater energy consumption. Therefore, reasonable pressure and speed settings are the key to reducing energy consumption.

Efficiency of heating and cooling systems: The heating system heats the plastic to a molten state, which is the main source of energy consumption. How to reduce heat loss during heating and improve the efficiency of the cooling system is an effective means to reduce energy consumption.

Efficiency of hydraulic system: The hydraulic system also consumes a lot of energy in the process of providing injection force and clamping force. Optimizing the design of the hydraulic system and reducing energy loss are also effective ways to improve energy efficiency.

2. Efficiency

Efficiency usually refers to the number and quality of products produced by the injection molding machine per unit time. A high-efficiency horizontal injection molding machine can not only reduce the production cycle, but also improve the overall production capacity. The main factors affecting the efficiency of injection molding machines include:

Injection cycle time: The length of the injection cycle directly affects production efficiency. An efficient injection molding machine can complete each link such as injection molding and cooling in a short time, thereby increasing the production rate.

Mold design: Reasonable mold design can improve the efficiency of injection molding. For example, a good cooling channel design can shorten the cooling time and improve production efficiency.

Automation degree: Injection molding machines with a high degree of automation can achieve fully automated operations from raw material delivery to finished product removal, reduce manual intervention, and improve production efficiency.

3. Stability and maintenance

The stability and maintenance of horizontal injection molding machines have an important impact on their long-term performance and production efficiency. Stable performance can not only reduce downtime during production, but also maintain product consistency and reduce scrap rate during production.

Equipment stability: The stability of equipment is usually closely related to its design, manufacturing quality and long-term use. A low failure rate in long-term operation means that the equipment can continue to operate efficiently.

Maintenance cycle and cost: The horizontal injection molding machine has a long maintenance cycle and low maintenance cost, which can reduce production losses caused by downtime and improve overall production efficiency.

Performance optimization methods for horizontal injection molding machines

1. Use frequency conversion technology

Frequency conversion technology controls the energy consumption of injection molding machines by adjusting the speed and power of the motor. The frequency converter can adjust the speed and power of the motor according to the actual load demand, thereby optimizing energy consumption under different production conditions.

Adjust energy consumption according to load changes: When the injection molding machine is in a no-load or light-load state, frequency conversion technology can automatically reduce energy consumption and avoid unnecessary energy waste.

Increase the response speed of the system: The frequency conversion drive can quickly respond to changes in load during the injection molding process, making the system run more smoothly and efficiently.

2. Optimize the design of the hydraulic system

The hydraulic system is one of the main sources of energy consumption in the horizontal injection molding machine. By optimizing the design of the hydraulic system, energy loss can be reduced and overall energy efficiency can be improved. Specific methods include:

Application of high-efficiency hydraulic pumps: Select high-efficiency hydraulic pumps and valves to reduce the energy consumption of the hydraulic system.

Optimization of hydraulic circuits: By optimizing the design of hydraulic circuits, reduce pressure loss and energy consumption in the hydraulic system, and improve the efficiency of the hydraulic system.

Low-noise, high-efficiency hydraulic components: Select low-noise and more efficient hydraulic components to further improve the overall performance of the hydraulic system.

3. Improve mold cooling system

The mold cooling system is an important factor affecting the energy efficiency and efficiency of the injection molding machine. The cooling process takes up a lot of time and energy. By improving the cooling system, energy consumption can be reduced and production efficiency can be improved.

Optimize the design of cooling channels: By rationally arranging the cooling channels, the cooling is uniform, avoiding overheating or overcooling in some areas, thereby improving the cooling efficiency of the mold.

Improve heat exchange efficiency: Select cooling media with good thermal conductivity to enhance the heat exchange effect and shorten the cooling time.

4. Automation and intelligent control

With the development of automation technology, horizontal injection molding machines are gradually developing in the direction of automation and intelligence. Through intelligent control systems, not only can production efficiency be improved, but also the operating status of the equipment can be monitored and adjusted in real time to optimize energy consumption performance.

Automatic adjustment of process parameters: The intelligent control system can automatically adjust the process parameters of the injection molding machine, such as injection speed, temperature and pressure, according to the real-time monitoring data to optimize production efficiency and energy consumption.

Preventive maintenance: The intelligent control system can identify the potential risks of equipment failure in advance, automatically warn and adjust, thereby reducing downtime and maintenance costs.

Comprehensive analysis of horizontal injection molding machine performance evaluation

1. Comprehensive energy efficiency evaluation

The comprehensive energy efficiency evaluation not only needs to pay attention to the energy consumption of each key system of the injection molding machine, but also needs to consider the synergy of each link in the entire production process. For example, the transportation of raw materials, the design and cooling of molds will affect the overall energy consumption performance. Therefore, a comprehensive evaluation of the energy efficiency of horizontal injection molding machines needs to be combined with the actual production situation and comprehensively consider multiple factors.

2. Balance between efficiency and cost

High-efficiency horizontal injection molding machines can often improve production capacity, but may also increase initial investment and maintenance costs. When evaluating horizontal injection molding machines, it is necessary to find a balance between efficiency and cost. By optimizing the process, improving the degree of automation, and reducing energy consumption, it is possible to reduce operating costs while ensuring high efficiency.

3. Continuous improvement and technology upgrade

The performance evaluation of horizontal injection molding machines is not only a static process, but also a dynamic optimization process. With the continuous advancement of technology, new high-efficiency components, intelligent control technologies and energy-saving solutions are constantly emerging, and the performance of equipment also needs to be continuously improved. Therefore, regular performance evaluation of horizontal injection molding machines and technical upgrades based on the evaluation results are effective ways to improve equipment performance, reduce energy consumption, and improve production efficiency.

Performance evaluation of horizontal injection molding machines is a multi-dimensional process involving energy efficiency, efficiency, equipment stability, degree of automation, and other aspects. In modern manufacturing, the energy efficiency and efficiency of injection molding machines directly affect production costs and product quality. Therefore, when selecting and using horizontal injection molding machines, companies need to consider various factors comprehensively to achieve reasonable configuration and optimized operation. Through continuous technological innovation and performance optimization, horizontal injection molding machines can reduce energy consumption and operating costs while ensuring production efficiency, meeting increasingly stringent production needs.
