What are the points that need to be paid attention to in automobile mold opening injection molding?

With the wide application of intelligent manufacturing technology, the automotive mold industry has gradually realized digital and intelligent manufacturing. Digital mold technology, such as three-dimensional design of molds and simulation of stamping and forming process (CAE), has become the mainstream direction. These technologies improve the reliability of mold design, reduce mold trial time, and make mold design change from empirical design to scientific design. Due to the increasing requirements of auto parts, high-precision automotive molds are becoming the mainstream of the development of the industry. At the same time, the automotive industry is facing the task of energy conservation and emission reduction, so energy-saving automotive molds have also ushered in great development. These molds not only improve production efficiency, but also reduce energy consumption and environmental pollution.


Automotive mold opening injection molding is a complex and delicate process that involves several critical steps and considerations. Here are a few things to keep in mind during the injection molding process:

1. Mold design: Mold design is the primary link of open mold injection molding, and its quality directly affects the quality and production efficiency of injection molded parts. The shape, size, precision requirements and injection molding process characteristics of the product should be fully considered in the design to ensure that the mold structure is reasonable, the strength is sufficient, and potential production problems can be effectively avoided.

2. Material selection: Choosing the right mold material is crucial to ensure the life of the mold and the quality of the injection molded parts. The material should have good wear resistance, heat resistance2 and corrosion resistance to cope with the challenges of high temperatures, high pressures and corrosive substances.

3. Injection molding process parameter setting: In the injection molding process, various process parameters need to be accurately set, such as injection pressure, temperature, speed and time. These parameters directly affect the molding effect and quality of the injection molded parts. Through reasonable parameter setting, good surface finish, dimensional accuracy and mechanical properties can be obtained.


4. Temperature control: Mold temperature is one of the key factors affecting the quality of injection molded parts. In the injection molding process, it is necessary to maintain the stability and uniformity of the mold temperature to avoid shrinkage, deformation and other problems caused by temperature changes, and at the same time, it is also necessary to pay attention to the layout of the cooling channel and the control of the cooling rate to ensure that the injection molded parts can be cooled quickly and uniformly.

5. Demoulding slope: A reasonable design of demoulding slope is the key to avoid problems such as product brushing and top injury. The demoulding slope should be reasonably selected according to the shape, material and process requirements of the product to ensure that the product can be smoothly removed from the mold.

6. Safety production: When carrying out the injection molding operation, the safety production specifications should be strictly adhered to to ensure the personal safety of the operator and the stable operation of the equipment. This includes wearing protective equipment, regularly checking the status of equipment, dealing with anomalies in a timely manner, etc.
