1. Basic knowledge of mold
All kinds of tools and products used in daily production and life range from the base of the machine tool, the shell of the fuselage, to the shell of a screw head, buttons, and various household appliances. They all have a close relationship with the mold. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. Because of the different materials, appearance, specifications and uses of various products, the molds are divided into non-plastic molds such as casting molds, forging molds, die casting molds, stamping molds, and plastic molds.
In recent years, with the rapid development of the plastic industry and the continuous improvement of strength and precision of general and engineering plastics, the application range of plastic products is also expanding, such as: household appliances, instruments, construction equipment, automotive industry, Japan In many fields such as hardware, the proportion of plastic products is rapidly increasing. A properly designed plastic part can often replace multiple traditional metal parts. The trend of plasticizing industrial products and daily-use products is increasing.

2. General definition of mold: In industrial production, various presses and special tools installed on the press are used to make parts or products of desired shapes through metal or non-metallic materials. Such special tools are collectively called molds. .
3. Description of injection molding process: The mold is a tool for producing plastic products. It is composed of several sets of parts, and there is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, then the upper and lower molds are separated, and the product is ejected from the cavity through the ejection system to leave the mold, and finally the mold is closed. For the next injection, the entire injection process is cyclic.
