The various tools and products we use in daily production and life, ranging from the base of machine tools and body shells to as small as a head screw, button and the shell of various household appliances, are all closely related to molds. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products. Because the materials, appearances, specifications and uses of various products are different, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, and stamping molds, as well as plastic molds.
In recent years, with the rapid development of the plastics industry and the continuous improvement in strength and precision of general and engineering plastics, the application scope of plastic products has also been expanding, such as: household appliances, instruments and meters, construction equipment, automobile industry, In many fields such as daily hardware, the proportion of plastic products is increasing rapidly. A well-designed plastic part can often replace multiple traditional metal parts. There is a growing trend towards the plasticization of industrial and daily products.
meaning
General definition of mold: In industrial production, various presses and special tools mounted on the press are used to make parts or products of the desired shape from metal or non-metallic materials through pressure. Such special tools are collectively called molds.
Injection molding process description: A mold is a tool for producing plastic products. It consists of several groups of parts with a mold cavity inside. During injection molding, the mold is clamped on the injection molding machine. The molten plastic is injected into the mold cavity and cooled and shaped in the cavity. Then the upper and lower molds are separated. The product is ejected from the mold cavity and away from the mold through the ejection system. Finally, the mold is closed again. For the next injection molding, the entire injection molding process is carried out in a cycle.
