A limit component 404 is symmetrically installed on the inner side of the sliding groove 402 near the front. A lifting component 405 is symmetrically installed on the top of the fixed base 401 near both sides. A plug-in component 406 is fixed to the top of the lifting component 405 corresponding to the connecting component 3. A guide component 407 is symmetrically installed on the top of the fixed base 401 and at the four corners, which can effectively guide the upper mold base 1.

[0031] Example 2:

[0032] like Figure 1-4 As shown, the limiting component 404 includes a first electric push rod 4041 fixedly connected to both sides of the fixed base 401. The output end of the first electric push rod 4041 and located inside the fixed base 401 are fixedly connected to a limiting block 4042, and the limiting block 4042 is slidably connected to the fixed base 401. The limiting component 404 can effectively limit the lower mold base 2.

[0033] The lifting assembly 405 includes a first fixing groove 4051 formed on the top of the fixed base 401. The interior of the first fixing groove 4051 extends to the top and is fitted with a second electric push rod 4052, which can effectively lift the upper mold base 1.

[0034] The plug-in assembly 406 includes a connecting block 4061 fixedly connected to the output end of the second electric push rod 4052 and adapted to and snapped into the connecting groove 301. A third electric push rod 4062 is symmetrically fixed inside the connecting block 4061, and the output end of the third electric push rod 4062 is plugged into the limiting groove 302, which can effectively connect with the connecting assembly 3.

[0035] The guide assembly 407 includes a second fixing groove 4071, and a guide roller 4072 is fitted inside the second fixing groove 4071.
