Plastic mold is a tool for plastic processing industry and plastic molding machine to give plastic products with complete shape and precise size. Due to the variety of plastics and processing methods, plastic molding machine and plastic products structure and simple and complicated, plastic mold types and structure is also a variety of.

A combination plastic mold for compression molding, extrusion, injection molding, blow molding and low foam molding, which mainly includes a concave mold with variable cavities composed of concave mold combination substrate, concave mold assembly and concave mold combination plate, and a convex mold with variable core composed of convex mold combination substrate, convex mold assembly, convex mold combination plate, cavity cut-off assembly and side cut-off combination plate. Coordinated change of mold convex and concave dies and auxiliary molding system. A series of plastic parts of different shapes and sizes can be processed.

With the rapid development of the plastics industry and the continuous improvement of general and engineering plastics in terms of strength and other aspects, the application of plastic products is also expanding, and the amount of plastic products is rising.

Plastic mold is a kind of tool for producing plastic products. It consists of several groups of parts parts, and this combination contains the molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity and cooled and shaped in the cavity, then the upper and lower molds are separated and the product is ejected from the cavity and leaves the mold through the ejector system, and finally the mold is closed again for the next injection, the whole injection process is cyclic.

Generally, the plastic mold consists of two parts: the moving mold and the fixed mold, the moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the mold and the fixed mold are closed to form the pouring system and cavity, and when the mold is opened, the mold and the fixed mold are separated in order to take out the plastic products.

Although the structure of the mold may vary depending on the variety and properties of plastics, the shape and structure of plastic products and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature regulating system, molding parts and structural parts. Among them, the pouring system and molding parts are the parts in direct contact with plastic and change with plastic and products, which are the most complicated and changeable parts in the mold and require the highest processing finish and precision.

The pouring system is the part of the flow channel before the plastic enters the cavity from the injection nozzle, including the main flow channel, cold cavity, manifold and gate. Molding parts are the various parts that constitute the shape of the product, including moving mold, fixed mold and cavity, core, molding rod and exhaust port, etc.

China's plastic mold in high technology driven and pillar industry application demand, the formation of a huge industrial chain, from the upstream of the raw and auxiliary materials industry and processing, testing equipment to the downstream of machinery, automobiles, motorcycles, home appliances, electronics and telecommunications, construction and building materials and several other major application industries, plastic mold development a vibrant.
