The locking groove 15 is formed by the three locking blocks 14, thereby locking and fixing the upper mold 5. Then the lower mold 6 drives the sliding bar 19 to be embedded in the sliding groove 18. At this time, the sliding bar 19 limits and fixes the lower mold 6. Then the second screw 21 drives the driving plate 22 to slide in the installation cavity 20. At this time, the driving plate 22 drives the locking plate 23 to be embedded in the locking groove 24 to lock and fix the sliding bar 19. Then the driving member 3 drives the upper mold 5 at the bottom of the driving member 4 to move downward and splice with the lower mold 6. At the same time, the driving member 4 slides on the outside of the limiting rod 27.
