What is the structure of the plastic mold? The plastic mold factory disassembled to show you
Mold injection molding is a processing method used for mass production of some complex-shaped parts. The specific principle is: the heated and melted plastic material is pushed into the cavity of the plastic mold with the screw of the injection molding machine under high pressure, and after cooling and solidification, the plastic molded product is obtained.
The plastic mold is composed of a movable mold and a fixed mold. 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 a gating system and a cavity. When opening the mold, separate the movable mold and the fixed mold to take out the plastic product.
Although the structure of the plastic mold may vary greatly depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, the basic structure is the same.
The structure of the plastic mold is divided by function
It is mainly composed of: pouring system, temperature control system, molding parts system, exhaust system, guiding system, ejection system and so on. Among them, the gating system and the molded parts are the parts that are in direct contact with the plastic and change. With plastics and products. They are the most complex part of plastic molds, which vary greatly and require high processing finish and precision.
Gate system: refers to the part of the runner before the plastic enters the cavity from the nozzle, including the main runner, cold block, runner and gate.
