The structure of the mold may vary depending on the variety and performance of the plastic, the shape and structure of the plastic product, and the type of injection machine, but the basic structure is consistent. The mold is mainly composed of pouring system, tempering system, forming parts and structural parts.
wherein the pouring system and molded parts are directly in contact with the plastic parts, and with the plastic and product changes, is the most complex plastic mold, the biggest change, the requirements of processing smoothness and the highest precision parts. The injection mold is composed of two parts: dynamic mode and fixed mode, and the movable die is installed on the mobile template of the injection molding machine, and the fixed mold is installed on the fixing formwork of the injection molding machine. During injection molding, the dynamic mode and the closing form are formed into the pouring system and the cavity, and the dynamic mode and the stationary die are separated in order to remove the plastic products. In order to reduce the heavy mold design and manufacturing workload, most of the injection mold adopts standard mold frame.
