Hello! It is produced by the following molds: all kinds of tools and products used in daily production and life, ranging from the base and body shell of machine tools to the shell of a head screw, button and various household appliances, all of which are closely related to the molds. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearance, specifications and uses of various products, the mold is divided into casting mold, forging mold, die casting mold, stamping mold and other non plastic mold, as well as plastic mold.
In recent years, with the rapid development of plastic industry and the continuous improvement of strength and precision of general and engineering plastics, the application scope of plastic products is also expanding, such as household appliances, instruments and meters, building equipment, automobile industry, daily hardware and many other fields, the proportion of plastic products is increasing rapidly. A well-designed plastic part can often replace multiple traditional metal parts. The trend of plasticization of industrial products and daily products is on the rise.
2. General definition of mould
In industrial production, with various presses and special tools installed on presses, metal or non-metal materials are made into parts or products with required shapes by pressure. Such special tools are collectively called dies.
3. Injection process description
Mold is a tool for producing plastic products. It consists of several groups of parts, which have a forming cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, cooled and shaped in the cavity, then the upper and lower molds are separated, the products are ejected from the mold cavity through the ejection system, and finally the mold is closed for the next injection, the whole injection process is cyclic.
