Our usual production, life used in a variety of things and goods, as large as the base of the machine tool, the body shell, as small as a embryonic head screws, buttons and a variety of household appliances shell, all have a close connection with the mold. The shape of the mold determines the shape of these goods, and the processing quality and precision of the mold also determines the quality of these goods. Because the material, appearance, standard and use of various commodities are different, the mold is divided into casting mold, forging mold, die-casting mold, stamping mold and other non-plastic mold, as well as plastic mold.
Over the years, following the rapid development of the plastics industry and the general and engineering plastics in terms of strength and precision, the use of plastic products are also expanding, such as: household appliances, instruments, construction devices, car industry, daily hardware and many other areas, the proportion of plastic products is rapidly increasing. A reasonable planning of plastic parts can usually replace more than one traditional metal parts. The trend of plasticization of industrial and daily-use goods is rising.
The general definition of mold: in industrial production, using a variety of presses and special things mounted on the press, through the pressure of metal or non-metallic materials to produce the required shape of parts or finished products, this special thing is collectively known as the mold.
Injection molding process clarification: mold is a kind of plastic finished products production things. It consists of several groups of parts, and there are molding cavities within this combination. When 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 finished product is ejected from the mold cavity through the ejector system, and then the mold is closed for the next injection, and the whole injection molding process is cyclic.
