[0027] Specifically, the top of the lower mold frame 1 is inserted into the positioning hole 7 at the bottom of the upper mold frame 5, and the locking pin 8 inside the positioning hole 7 is inserted into the interior of the positioning pin 3, so that the lower mold frame 1 and the upper mold frame 5 are tightly connected. Furthermore, under the elastic action of the support spring 14, the locking rod 16 squeezes the locking ball 18 through the locking head 1601 to make it lock into the locking groove 4, so that the lower mold frame 1 and the upper mold frame 5 are fixedly connected.

[0028] When disassembling the lower mold frame 1 and the upper mold frame 5, simply press down the connecting rod 24 to compress the support spring 14 with the pressure rod 13. The pressure rod 13 pushes the locking rod 16 down, and the locking rod 16 drives the lock head 1601 down, so that the locking ball 18 rolls inward under the guidance of the inclined hole 17 and comes out of the lock groove 4. Then lift up the upper mold frame 5 to separate the locking pin 8 from the positioning pin 3 and the positioning pin 3 from the positioning hole 7. The pressing disassembly method greatly reduces the workload compared with the bolt disassembly method. It is simple, fast and quick to operate, short in time and high in disassembly efficiency.

[0029] Both the lower mold base 1 and the upper mold base 5 have a groove 9 at the corner of the bottom, and a push spring 10 is installed inside the groove 9. The top of the push spring 10 is fixed with a top block 11, and the top block 11 is in close contact with the lower mold core 2.

Mounting blocks 20 have mounting holes 21 inside, and mounting bolts 22 are installed inside the mounting holes 21. The mounting bolts 22 are threadedly connected to the threaded holes 23.

[0036] Specifically, when the mounting bolt 22 is unscrewed from the threaded hole 23, the top block 11 pushes out the lower mold core 2 and the upper mold core 6 under the elastic action of the push spring 10, so as to facilitate the removal of the lower mold core 2 and the upper mold core 6 from the lower mold frame 1 and the upper mold frame 5, and facilitate the replacement of the lower mold core 2 and the upper mold core 6.

[0037] In this embodiment, the following steps are taken: First, the top of the lower mold frame 1 is inserted into the positioning hole 7 at the bottom of the upper mold frame 5. The locking pin 8 inside the positioning hole 7 is inserted into the positioning pin 3, making the lower mold frame 1 and the upper mold frame 5 tightly connected. Further, under the elastic action of the support spring 14, the locking rod 16, through the locking head 1601, presses the locking ball 18, causing it to engage in the locking groove 4, thus fixing the lower mold frame 1 and the upper mold frame 5 together. When disassembling the lower mold frame 1 and the upper mold frame 5, simply press down the connecting rod 24 to compress the support spring 14 with the pressure rod 13. The pressure rod 13 pushes the locking rod 16 downwards, and the locking rod 16 drives the locking head 1601 downwards, thus... Under the guidance of the inclined hole 17, the locking ball 18 rolls inward and disengages from the locking groove 4. Then, the upper mold frame 5 is lifted to separate the locking pin 8 from the positioning pin 3, and the positioning pin 3 from the positioning hole 7. The pressing disassembly method greatly reduces the workload compared to the bolt disassembly method. The operation is simple, fast, and time-saving, with high disassembly efficiency. Then, the mounting bolt 22 is unscrewed from the threaded hole 23. At this time, the top block 11 pushes out the lower mold core 2 and the upper mold core 6 under the elastic action of the pushing spring 10, so as to facilitate the removal of the lower mold core 2 and the upper mold core 6 from the lower mold frame 1 and the upper mold frame 5, and facilitate the replacement of the lower mold core 2 and the upper mold core 6.
