[0035] Specifically, in the mold frame system, when different molds need to be positioned, the positioning rod 3 can be directly pressed, the positioning rod 3 drives the connecting block 7 to move downward, and the conical block 8 connected thereto also moves downward, which compresses the spring 10 in the process. Once the spring 10 is compressed, the limiting of the ball 6 is released, at which time the ball 6 slides out from the inside of the clamping groove 5 and slides in the limiting groove 9. In this way, the sliding block 4 can freely slide in the sliding groove 2, so that the position can be conveniently adjusted. When adjusted to the appropriate position, release the positioning rod 3, the spring 10 rebounds, drives the conical block 8 to move upward, and then pushes the ball 6 to clamp into the clamping groove 5, realizes fixation, ensures stable positioning of the mold, thereby reducing the debugging time and improving the efficiency of mold debugging. For example, in an injection mold, the relative position of the core and the cavity can be quickly adjusted by moving the positioning rod 3 transversely, ensuring the molding quality of the product.

[0036] Referring to Figure 1 , Figure 3 and Figure 4 , the disassembly and assembly assembly includes a connecting column 11 made of high-strength stainless steel material. This material not only has good corrosion resistance, but also can withstand a large torque.
