The injection mold consists of two parts: the moving mold, which is mounted on the moving template of the injection molding machine, and the fixed mold, which is mounted on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the pouring system and the cavity, and the moving mold and the fixed mold are separated when the mold is opened in order to take out the plastic products.
Although the structure of the mold may vary greatly due to the variety and properties of the plastic, the shape and structure of the plastic product and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature control system, molding parts and structural parts. Among them, the pouring system and molding parts are in direct contact with the plastic and change with the plastic and products, which are the most complicated and changeable parts of the mold and require the highest processing finish and precision.
The casting system refers to the part of the runner before the plastic enters the cavity from the injection nozzle, including the main runner, the cold material cavity, the manifold and the gate. Molding parts refer to the various parts that constitute the shape of the product, including the moving mold, fixed mold and cavity, core, molding rod and exhaust port.
