The upper mold base plate 1, the upper mold cover plate 2, and the upper mold body 3 are fixedly connected to each other by bolts to form an integral structure that can move synchronously.

[0030] In some embodiments of this utility model, the upper mold cover plate 2 is symmetrically provided with upper mold cover plate guide post holes 4 that cooperate with the guide post 10.
