Mold injection molding is a processing method used in mass production of complex parts of certain shapes. The specific principle refers to: the plastic raw material melted by the heat is injected from the screw of the injection molding machine into the cavity of the plastic mold, and after cooling and solidifying, the plastic formed product is obtained. Today, the mold manufacturer said that the composition system of the plastic mold structure has several aspects: The plastic mold consists of two parts: the movable mold and the fixed mold. The movable mold is mounted on the moving template of the injection molding machine, and the fixed mold is fixed in the injection molding machine.
On the template. In the injection molding, the movable mold and the fixed mold close constitute a casting system and pipe fitting mould factory a cavity, and when the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. Although the structure of the plastic mold may vary depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is uniform. The plastic mold structure is divided into functions, mainly consisting of: pouring system, temperature regulation system, molding part system, exhaust system, guiding system, and ejection system.
The gating system and the molded part are in direct contact with the plastic and vary with the plastic and the product. It is the most complicated and most varied part of the mold, and requires the highest degree of smoothness and precision. In fact, the plastic mold is not difficult, no matter how the plastic product changes, for the mold to form the plastic product, its structure is nothing more than the above aspects.
