Injection molds are a tool for producing plastic products and also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to the high-pressure injection of heated and molten plastic into the mold cavity by the injection molding machine, and after cooling and solidification, the molded product is obtained.

[0003] Some injection molded parts can be formed and assembled into different components and models. In order to protect the model, a shell is set on the outside of the position, and most of the shells are installed and tightened by screws and other tightening parts. This tightening method requires using a screwdriver to remove the screws little by little during disassembly before the shell can be replaced. This method can only be used for injection molded parts that do not need to be replaced for a long time. For injection molded parts that are severely worn and need long-term replacement, this method is not suitable for equipment use, and disassembly and replacement are not practical.
