[0012] In a specific implementation manner, bearings are embedded on both sides of the lower mold, and the bidirectional lead screw is interference fit with the inner ring of the bearing.

[0013] In the above implementation process, the loss caused by the rotation can be easily reduced through the interference fit between the bidirectional lead screw and the inner ring of the bearing.

[0035] In the specific setting, the limiting assembly 240 includes a slide bar 241, a fixed block 242 and a spring 243. The slide bar 241 is slidably connected to the lower mold 110, and the slide bar 241 is clamped with the die body 120. The fixed block 242 is arranged at one end of the slide bar 241, and the two ends of the spring 243 are respectively connected to the fixed block 242 and the lower mold 110.

[0036] In a specific configuration, both sides of the die body 120 are provided with slots 130 , and the slide bar 241 is engaged with the slots 130 . The engagement of the slide bar 241 with the slots 130 facilitates the connection between the slide bar 241 and the die body 120 .
