[0002] Injection molding is a method of producing products, and products are usually made of rubber and plastic injection molding. The process of injection molding production is to use an injection molding machine to use plastics to form products of various shapes using injection molding molds, so as to achieve rapid production and manufacturing of products.

[0003] At present, in the production process of existing injection molds, after producing one product model, when it is necessary to change the mold to produce another product, the existing mold core is hung at the bottom of the mold core, which causes the mold to be removed from the injection molding machine, and the mold must be completely disassembled after being removed to achieve the mold core replacement (i.e., mold change). This leads to a long mold change cycle, a large workload for mold change, a large amount of human resources, and a long downtime of the injection molding machine, thereby affecting the efficiency of product production.
