In our daily life and industrial production, we often use a variety of plastic mold industrial supplies, large machine tools of various plastic molds, fuselage plastic shells, small household appliances and a variety of household appliances, each of which has a close relationship with plastic molds. The shape of the plastic mold determines the shape of these products, and the quality and precision of the processing also determines the quality of these products. Because of the different materials, appearance, specifications and uses of this plastic mold product, it is divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds.
　　in recent years，In our daily life and industrial production, various types of plastic molds and industrial products are often used, ranging from various plastic molds for machine tools and body plastic shells to small household items and various household appliance shells, all of which are closely related to plastic molds. The shape of plastic molds determines the appearance of these products, and the quality and precision of processing also determine the quality of these products. Due to the different materials, appearances, specifications, and uses of this plastic mold product, it is divided into non plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds.
　　The general definition of plastic molds: In industrial production, various presses and specialized tools installed on the press are used to produce parts or products of the desired shape from metal or non-metallic materials through pressure. These specialized tools are collectively referred to as molds.
　　During the injection molding process, it should be noted that plastic molds are a tool for producing plastic products. It consists of several sets of parts, with a forming cavity inside this combination. During injection molding, the plastic mold is clamped onto the injection molding machine, and the molten plastic is injected into the mold cavity, cooled and shaped inside the cavity. Then, the upper and lower molds are separated, and the product is ejected from the mold cavity through the ejection system. Finally, the mold is closed for the next injection molding, and the entire injection process is cyclic.
