Technical Field

[0001] The utility model relates to the technical field of injection heads that are convenient to replace, and particularly relates to an injection head of an injection molding machine that is convenient to replace. Background Art

[0002] Injection molding is a method for manufacturing industrial product shapes; products usually use rubber injection molding and plastic injection molding; injection molding can also be divided into injection molding, compression molding, and die-casting methods; an injection molding machine, abbreviated as an injection machine or an injection molding machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting materials. Injection molding is achieved through an injection molding machine and a mold.

[0003] In the injection molding process, the injection head is one of the key factors determining product quality and production efficiency. However, traditional injection head designs often have problems with difficult replacement, which not only affects production efficiency but also increases production costs and the labor intensity of workers. To solve these problems, in recent years, a new type of injection head for an injection molding machine that is convenient to replace and its replacement device have emerged. Traditional injection head designs are usually closely connected to the injection conduit to form an integrated structure. When the injection head needs to be replaced, operators often need to disassemble the entire injection conduit, which undoubtedly increases the complexity and time cost of replacement. In addition, due to the problem of residual injection raw materials, frequent replacement of the injection head may also lead to unstable product quality. Summary of the Utility Model
