Injection molding is one of the processing methods for mass production of plastic products.
The basic principle of injection molding is:
The hot-melted plastic raw material is pushed from the screw of the injection molding machine into the cavity of the injection mold, and after cooling and solidifying, the plastic formed product is obtained.
The injection mold consists of two parts:
The movable mold is mounted on the moving template of the injection molding machine
The fixed mold is mounted on the fixed template of the injection molding machine
In the injection molding, the movable mold and the fixed mold close constitute the casting system and the cavity
The movable mold and the fixed mold are separated when the mold is opened
So that the plastic product can be separated from the plastic mold.
Although the structure of the mold differs depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is uniform
