[0025] It is worth mentioning that, through the coordinated arrangement of the assembly groove 2, the limit bar 15, the mounting frame 17, the limit assembly, the positioning assembly and the clamping assembly, the mold can be conveniently assembled, and the mold can be disassembled and replaced in time as needed, thereby reducing the tediousness of disassembly and installation, further improving the efficiency of maintenance and replacement, and effectively ensuring the working efficiency of the equipment.

[0026] The limiting assembly includes: a limiting baffle 10 slidably connected to the inner wall of the mounting groove 3, and an anti-dropping clamping plate 11 connected to the top of the limiting baffle 10; wherein, positioning shafts are connected to both sides of the bottom of the limiting baffle 10, and a compression spring 12 is arranged inside the mounting groove 3, and the top end of the compression spring 12 is sleeved on the surface of the positioning shaft.

[0027] Among them, the limit baffle 10 is a structure for assembling the anti-dropout clamping plate 11, and the anti-dropout clamping plate 11 serves as a structure for limiting and preventing the lower mold 14 from dropping out. The compression spring 12 acts on the limit baffle 10 to make the anti-dropout clamping plate 11 extend outward, thereby improving the stability of the assembly of the lower mold 14.
