The L-shaped plate 31 is located inside the clamping groove 34, and the bottom of the L-shaped plate 31 is in contact with the top of the extrusion spring 35. The positioning rod 38 crosses the inside of the insertion hole 32, and the end of the positioning rod 38 away from the pulling cover 39 is clamped in the inside of the rubber tube 36, and there is resistance between the positioning rod 38 and the rubber tube 36.

[0028] In this embodiment: by setting the mold body 1 and the base 2, when the mold body 1 needs to be installed on the top of the base 2, the mold body 1 is first placed above the base 2, and then the L-shaped plate 31 on the outside of the mold body 1 will enter the inside of the clamping groove 34, and then the positioning rod 38 is driven to move inside the movable tube 37 by pulling the cover 39, so that the positioning rod 38 crosses the inside of the insertion hole 32, and one end of the positioning rod 38 enters the inside of the rubber tube 36.
