The injection mold consists of two parts: dynamic mold and fixed mold. The movable mould is installed on the mobile template of the injection molding machine, and the fixed mould is installed on the fixed template of the injection molding machine. In the injection molding, the dynamic and fixed die closed form the gating system and the mold cavity, and the moving and fixed modes are separated to remove the plastic products. In order to reduce the heavy work of mould design and manufacture, most of the injection mould has adopted the standard mold frame.
