Plastic injection molding is a processing method for mass production of some messy-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.
20L Pail Mould is composed of movable mold and 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 casting 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 variety and function of the plastic, the shape and structure of the plastic product, and the type of injection molding machine, the basic structure is the same. It is mainly composed of: pouring system, temperature control system, molding parts system, exhaust system, guiding system, ejection system, etc. In the meantime, the casting system and molded parts are parts that directly touch the plastic and change with the plastic and the product. They are the messiest parts in plastic molds, which have changed a lot and require high processing precision 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.
