[0041] Different from the traditional fastening structures such as bolts and nuts, the second quick-release structure 220 can be disassembled quickly, and the accessories do not need to be disassembled to prevent loss. The second quick-release structure 220 can effectively improve the speed of mold closing and mold opening, improve the production speed, and has various connection methods. The second quick-release structure 220 can be used to connect the outer mold frame 104 and the side mold frame 105, and can also be used to connect the side mold frame 105 and the inner mold assembly 102 or the inner mold assembly 102 and the outer mold frame 104; the second base 221 can be set on the desired mold frame, and the second hinge structure 2 22 is hinged with the second base 221, so that the second quick-release structure 220 can rotate as a whole in the desired fixing direction. A second rotating structure 223 is provided between the third hinge structure 224 and the second hinge structure 222, so that the third hinge structure 224 and the second fixed structure 225 subsequently connected thereto can rotate jointly, thereby increasing the flexibility of the structure and facilitating the second fixed structure 225 of this embodiment to be inserted into the matching card slot 229. The second quick-release structure 220 has a flexible structure and is more suitable for the fastening connection between two convex and misaligned mold frames.

[0042] In this embodiment, taking the second quick-release structure 220 between the bottom plate 106 and the side mold frame 105 as an example, since the structure is closer to the bottom surface, the range of movement is limited and it is difficult to activate, in order to facilitate the flexibility of disassembly and assembly at the bottom, the second base 221 is arranged on one side of the bottom plate 106, and the second hinged structure 222 is hinged to the second base 221, so that the second quick-release structure 220 at the bottom can be rotated upward as a whole, and the second fixed structure 225 is on the outside for easy disassembly and assembly. Among them, the second fixed structure 225 is a protruding block arranged on both sides of the second hinge part 226, and the side mold frame 105 is also provided with a slot seat 229 with a groove matching the second fixed structure 225. The second rotating structure 223 facilitates the second fixed structure 225 to rotate into the groove. The second hinge part 226 is arranged so that the second quick-release structure 220 can be clamped in the dead point position by depressing the second hinge part 226. The second hinge part 226 can be provided with a space for conveniently placing a prying structure such as a crowbar, or a protruding structure for conveniently pulling the second hinge part 226 is provided on one side of the second hinge part 226; further, the second fixed structure 225 can be a slot structure, which is clamped with a protrusion arranged on the side mold frame 105; the second fixed structure 225 can also be a connecting structure such as a hook structure.
