According to statistics, the daily necessities of an ordinary person are directly or indirectly related to about 2,000 sets of molds. It can be said that the degree of development of the mold industry has become one of the important signs of a country's industrial modernization. Therefore, in our daily life, whether it is used or not, it is more or less related to molds, such as plastic chair injection mould . 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. The materials, uses, specifications and appearance of different products will change. Molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds and plastic molds.
The application scope of plastic products is constantly expanding, such as household appliances, automobile industry, hardware products and many other fields. The proportion of plastic products is increasing rapidly. Reasonable plastic parts can usually replace multiple traditional metal parts.
The molds we use in our daily lives are tools for producing plastic products. It consists of several sets of parts, and there is a cavity in this combination. In the injection molding process, the mold is clamped on the injection molding machine, the molten plastic is injected into the mold cavity, cooled and molded in the cavity, and then the upper and lower molds are separated, and the product is taken out from it. Cavity. Take it out of the mold through the ejection system, and finally close the mold. For the next injection, the entire injection molding process will be executed cyclically.
The biggest feature of the plastic injection molding process is replication, it can replicate any product in the required quantity, and these products can be used directly or processed in a small amount. This is a process suitable for mass production. Despite a large investment in equipment, the number of products that can be produced is very large. This is actually an economical and fast production method, so it has been widely used and developed rapidly. The household product mould is also formed in this way.
