[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification.

[0003] After injection molding, it is not convenient to take out the cooled and molded product from the existing injection mold, which reduces work efficiency. In the plastic injection molding process, the mold temperature has a very important influence on the product quality and productivity. In addition, when the existing injection mold is heated up, it is easy for the mold to be heated unevenly, resulting in easy deformation of the product, thereby reducing the quality of the injection molded product. When the temperature is lowered, the mold temperature cools unevenly, and it takes a longer time for the product to cool. It is difficult to effectively and timely adjust the mold temperature after injection molding, which reduces the production efficiency of the injection molded product. Therefore, it is necessary to design an injection mold that is easy to control temperature. Utility Model Content
