[0004] When this patent is in use, the molded parts are fixed on the conveyor chain, which makes it inconvenient to disassemble the molded parts. When a molded part in the molding system is damaged, it takes a lot of time to disassemble the molded part for replacement, which increases the time cost. Utility Model Content

When a molded part in the molding system is damaged, it takes a lot of time to disassemble the molded part for replacement, which increases the time cost.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a bellows circulating forming mold, comprising a workbench and a circulating drive assembly, the circulating drive assembly is arranged on the workbench, the number of the circulating drive assemblies is two and they are symmetrically arranged, a plurality of forming molds are arranged on the circulating drive assembly, a fixing mechanism for easy disassembly is arranged between the forming mold and the circulating drive assembly, and a cooling mechanism is arranged on the plurality of the forming molds;

[0007] The fixing mechanism includes a fixing plate, an installation cavity, a first fixing bolt and a second fixing bolt. The fixing plate is arranged on a circulating drive assembly. The fixing plate is arranged corresponding to the forming mold. The installation cavity is arranged on the fixing plate. One end of the forming mold is located in the installation cavity. The first fixing bolt passes through the fixing plate and extends to the circulating drive assembly. The second fixing bolt passes through the fixing plate and extends to the forming mold.

When two molding dies are in contact, a complete mold can be formed. When the circulation drive component continues to drive the molding die to move, when the molding die reaches one end of the circulation drive component, the two molding dies in contact are separated to form a cycle. Then the fixing mechanism can facilitate the molding die on the circulation drive component to be fixed. The bellows can be disassembled, and then the cooling mechanism can cool the bellows in the process of forming, so that when the two forming molds are separated, the bellows can be completely formed, wherein the fixing mechanism includes a fixing plate, a mounting cavity, a first fixing bolt and a second fixing bolt. When in use, first the first fixing bolt mounts the fixing plate on the circulation drive assembly, and the fixing plate is arranged corresponding to the forming mold, the mounting cavity on the fixing plate can mount the forming mold, and the forming mold is fixed in the mounting cavity by the second fixing bolt, and fixed by the first bolt and the second bolt.
