Plastic mold, as a tool for producing plastic products, has an important impact on production. With the rapid development of the plastic industry, the continuous improvement of the strength of general plastics and engineering plastics, the scope of application of plastic products is also expanding, the amount of plastic products is also increasing. Because of the diversity of plastic and processing methods, the structure of plastic molding machines and plastic products is both complex and simple, so the types and structures of plastic molds are diverse.

Plastic molds, also known as injection molds, are composed of several sets of parts, and the combination contains a molding cavity. Injection molding, the mold is clamped in the injection molding machine, the molten plastic is injected into the mold cavity, and in the cavity, cooling finalize the design, and then the upper and lower mold is separated, through the ejection system products from the mold cavity out of the mold, and finally, the mold is closed for the next injection. Mold is a key manufacturing process in the manufacturing industry. Countries all over the world attach great importance to the development trend of the mold industry, which is one of the key bases of industrial development trends and social and economic development trends. As machinery and equipment industry (the streets) can be seen everywhere in the automobile, motorcycle industry, electronics industry products (home appliances), articles for daily use industries, dining-room, kitchen equipment, etc.), the development trend of increasing demand for plastic molding product, the product quality, and appearance is becoming more and more exquisite, quality supervision is becoming higher and higher. This has promoted the development of plastic mold design, the formulation of the design scheme, the improvement of production and manufacturing levels.

Because each pair of molds is a special fixture for the production of specific product parts, the mold design varies with the shape, size, and accuracy of industrial product parts, surface quality requirements, and molding process conditions. Therefore, each mold must be creative design, industrial production generally adopts the mold molding process method, in order to improve production efficiency and product quality. General press processing, an ordinary press design can produce several to dozens of parts per minute, high-speed press production efficiency has reached hundreds or even thousands of parts per minute. Thus it can be seen that the mold as a piece of special process equipment, in the production of the decisive role and important position for people gradually consensus
