The lower end surface of the stripping limiter 80 is concavely provided with a clearance groove 801 that cooperates with the product.

[0043] The working principle of this embodiment is described in detail as follows:

[0044] When stamping begins, the elastic member 50 drives the lower die seat 20, the lower die float 30 and the lower die insert 40 to reset, and prevents the product with the material strip from being in the molding cavity 101; at this time, the upper end surface of the lower die float 30 and the lower die seat 20 is flush with the product material strip, and then the upper die 93 moves downward, and the insert 60 first contacts the seat body 41 and drives the seat body 41 to move toward the lower die molding 10, and the molding insert 42 moves with the seat body 41 to the molding cavity 101 and is inserted The product inside the molding cavity 101; then the upper mold 93 continues to move downward, and the stripping limiter 80 is pressed down to the lower mold float 30 and the product is positioned. When the upper mold 93 continues to press down, the stripping molding 70 enters the molding cavity 101. At this time, the lower mold seat 20, the lower mold float 30, and the lower mold insert 40 all move downward under the action of the upper mold 93. When they move to the bottom, the molding part 71 completes the process of enclosing the product by cooperating with the molding cavity 101. Finally, the upper mold 93 moves upward, and the elastic member 50 drives the lower mold seat 20, the lower mold float 30, and the lower mold insert 40 to reset, and take out the molded product.
