The Structure of Injection Mold

2020-04-30

Injection mold is a process used in the mass production of parts with complex shapes.Specific principle refers to: the heat melting of plastic raw materials by the injection molding machine screw into the high pressure injection mold cavity, after cooling and curing, plastic forming products.

The plastic injection mold is composed of moving mold and 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 moving mold and the fixed mold close to form the pouring system and cavity. When the mold is opened, the moving mold and the fixed mold are separated to take out the plastic products.Although the structure of the mold may vary greatly due to 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, tempering system, forming parts and structural parts.Pouring system and molding parts are directly in contact with plastic parts, and with the plastic and products and changes, is the most complex in the mold, the largest change, the requirements of processing finish and precision of the highest part.

An injection mold is a tool for producing plastic products.It is also a tool to give plastic products complete structure and precise size.Injection molding is a process used in the mass production of parts with complex shapes.Specifically refers to the heat melting of the plastic by injection molding machine high pressure into the mold cavity, after cooling and curing, to form the product.Although the structure of the mold that makes up the mold may vary greatly due to 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, tempering system, forming parts and structural parts.Pouring system and molding parts are directly in contact with plastic parts, and with the plastic and products and changes, is the most complex in the mold, the largest change, the requirements of processing finish and precision of the highest part.The injection mold is composed of two parts: moving mold and 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 moving mold and the fixed mold close to form the pouring system and cavity. When the mold is opened, the moving mold and the fixed mold are separated to take out the plastic products.In order to reduce the heavy work of mold design and manufacturing, most injection mold adopts standard mold frame.
