What are the two parts that make up a plastic mold

Mold injection molding is a processing method used in mass production of complex shaped components. The specific principle refers to the high-pressure injection of melted plastic raw materials into the mold cavity of a plastic mold through the screw of an injection molding machine, followed by cooling and solidification to obtain plastic molded products.

A plastic mold consists of two parts: a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, while the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the dynamic and fixed molds are closed to form a pouring system and cavity. When opening the mold, the dynamic and fixed molds are separated to facilitate the removal of plastic products.

The structure of the mold may vary greatly due to differences in plastic varieties and properties, shapes and structures of plastic products, and types of injection machines, but the basic structure is consistent. The mold is mainly composed of a pouring system, a temperature control system, molded parts, and structural parts. The pouring system and molded parts are the parts that come into direct contact with the plastic and vary with the plastic and the product. They are the most complex and variable parts in the mold, requiring the highest processing smoothness and accuracy.

Injection mold is a tool for producing plastic products; It is also a tool that endows plastic products with complete structure and precise dimensions. Injection molding is a processing method used in mass production of complex shaped components. Specifically, it refers to injecting melted plastic under high pressure from an injection molding machine into a mold cavity, cooling and solidifying it to obtain a molded product.
