When the pressure between the upper die base 21 and the lower die base 22 reaches the set requirements, the molding and pressing of the product can be completed.

[0033] The visual inspection device 4 is arranged at the side end of the press body 1, and the visual inspection device 4 is used to detect whether there is residual adhesive material at the bottom of the upper mold base 21 and the top of the lower mold base 22.
