How to choose the opening mechanism of plastic injection mold

1. What is injection molding processing?

Injection molding is also called injection molding, which is a molding method of injection and molding. At a certain temperature, the completely melted plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

The injection molding process can be roughly divided into the following six stages: mold clamping, injection, pressure holding, cooling, mold opening, and product removal.

2. Injection mold structure

As we all know, injection molds are mainly composed of seven major systems: guiding system, supporting system, molding parts system, pouring system, cooling system, ejection system, and exhaust system. The above systems make up the mold. The plastic enters the cavity through the pouring system through the gate, and is cooled by the cooling system after filling and holding pressure. The finished product is condensed and solidified and ejected by the ejection system to complete a molding cycle.

According to product structure differences and cost considerations of mold design, manufacturing and mass production, general injection molds can be divided into: general two-plate mold and three-plate mold.

3. How to choose the mold opening mechanism of the mold?

Based on the structure type of the actual mold design of the three-plate mold, let's talk in detail about how we should choose the appropriate auxiliary mold opening mechanism in the mold design stage.
