The precision injection molding mold is composed of two parts: moving and fixed mold. The motion mold is installed on the mobile template of the injection molding machine. The fixed mold is installed on the fixed template of the injection molding machine. During the injection molding, the motion mold and fixed mold closed form the pouring system and cavity. When the mold is opened, the motion and fixed mold separation is separated to remove the plastic products.
Although the structure of the mold may be ever -changing due to different plastic varieties and performance, the shape and structure of plastic products, and the type of injection machine, the basic structure is consistent. The mold is mainly composed of pouring system, temperature regulation system, formation parts and structural parts. Among them, the pouring system and the molding parts are the direct contact part with the plastic, and change with the plastic and products. It is the most complicated, the most changing part in the plastic mold, and requires the highest processing of processing and the highest accuracy.
The pouring system refers to the flow channel part of the plastic from entering the mouth into the cavity, including mainstream lanes, cold ingredients, downshills and ports. Modeling parts refer to various parts that constitute the shape of the product, including motion, molding and cavity, cores, forming rods, and exhaust ports.
