    The plastic mold is a tool that is matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise size. The different molding methods can be divided into different types of molds. Through the cooperation of various systems or auxiliary mechanisms in the mold, the plastic particles are liquefied and filled into the mold cavity at high temperature, and a tool for producing industrial parts with a specific shape, size, function, and quality.

    When the single parting surface injection mold is opened, the movable mold and the fixed mold are separated to take out the plastic parts, which is called a single parting surface mold, also known as a double-plate mold. It is the simplest and most basic form of injection mold. It can be designed as a single-cavity injection mold or a multi-cavity injection mold according to needs. It is the most widely used injection mold.

    The double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds a partially movable intermediate plate (also called the movable gate plate, There are gates, runners, and other parts and components required for the fixed mold), so it is also called a three-plate (moving template, intermediate plate, fixed template) injection mold, which is often used for single-type gate feeding. In cavity or multi-cavity injection mold, when the mold is opened, the intermediate plate is separated from the fixed plate by a certain distance on the guide column of the fixed mold, so that the pouring system condensate can be taken out between the two plates.

    The double-parting surface injection mold has a complex structure, high manufacturing cost, and difficult parts processing. It is generally not used for the molding of large or extra-large plastic products.
