[0002] Nowadays, two-color injection molding has been widely applied to almost all plastic fields such as electronic products, power tools, medical products, household appliances, toys, etc. At the same time, the production and molding of two-color molds, as well as the research and development of two-color and multi-color injection molding machines and two-color injection molding raw materials, have also developed rapidly. Two-color injection molding refers to the molding process of injecting two different materials into the same set of molds, so that the molded parts are formed by two materials. Some of the two materials are of different colors, and some are of different hardnesses, thereby improving the aesthetics and assembly performance of the products. Due to the special molding method of two-color injection molding, which requires mutual cooperation and coordination, the two molds need to rotate relative to each other. How to effectively shorten the mold transfer time and improve the mold transfer speed, thereby improving production efficiency, is one of the long-term research topics of enterprises. Summary of the Invention

The mold mounting surface at station one is installed on the left side of the mold transfer assembly body. A bearing seat is installed on the right side surface of the mold mounting surface at station one. Large holes are provided on the front and rear surfaces of the bearing seat.
