Structure of plastic mould

What is the structure of plastic mold? Let's discuss and exchange with plastic mold manufacturers.

Plastic mold manufacturers tell you: injection molding of plastic mold is a processing method for mass production of some disorderly shaped parts. The specific principle is to push the heated and melted plastic raw materials into the cavity of plastic mold with the screw of injection molding machine under high pressure, and obtain plastic molded products after cooling and curing.

Plastic mould is composed of movable mould and fixed mould. The movable mold is installed on the movable 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 movable mold and the fixed mold are closed to form the pouring system and cavity. When opening the mold, separate the movable mold from the fixed mold to take out the plastic products.

Although the structure of plastic mold may vary greatly due to the variety and function of plastic, the shape and structure of plastic products and the type of injection molding machine, the basic structure is the same. It is mainly composed of pouring system, temperature control system, forming part system, exhaust system, guiding system, ejection system, etc. In the meantime, the pouring system and molded parts are parts that are directly touched with plastics and change with plastics and products. They are the most cluttered parts in plastic molds, which have changed greatly, and the machining accuracy and precision requirements are also very high. Gate system: it refers to the part of the runner before the plastic enters the cavity from the nozzle, including sprue, cold block, runner and gate, etc.
