A compression spring 26 is provided between the second abutment block 24 and the first slot 27. A first abutment block 23 is fixedly connected to the outside of the positioning rod 22. One side of the first abutment block 23 abuts against one side of the second abutment block 24.

[0024] When the lower stationary mold 1 and the upper moving mold 3 are closed, both ends of the moving block 21 are inserted into the interior of the second slot 28, and the positioning rod 22 passes through the middle of the second abutment block 24. First, the first abutment block 23 contacts the second abutment block 24, pushing the second abutment block 24 into the interior of the first slot 27. The compression spring 26 is compressed, and one end of the positioning rod 22 passes through the positioning block 25, which facilitates the guidance and positioning of the outer side of the lower stationary mold 1 and the upper moving mold 3.
