The production process of plastic molds is as follows:

1. During injection molding, the mold is clamped onto the injection molding machine, and molten plastic is injected into the mold cavity, where it is cooled and shaped.

2. Separate the upper and lower molds, and use the ejection system to eject the product from the mold cavity and leave the mold.

3. The mold is closed again for the next injection molding, and the entire injection process is cyclic.

It is understood that as a tool for producing plastic products, plastic molds are composed of several sets of parts, which have a molding cavity inside. In industrial production, plastic molds can be used to produce parts or products of the desired shape from metal or non-metallic materials through pressure.
