していた。However, in the above conventional configuration, the stripper
4 is an integrally processed product of urethane rubber, so the stamper
There are variations in the distribution of the force that presses down the stamper 3, and after the punching process, as shown in Figure 2, a warp 5 occurs on the outer periphery of the stamper 3, which prevents it from being attached to the mold during molding, and air leaks during molding. The problem was that it was not possible to mold a good product due to the leakage.

The basic operation is exactly the same as that of the conventional example. That is, first, the lower mold 2 and the stamper 3 are separated and processed by the upper mold 1. When the lower die 2 reaches the top dead center, it begins to descend, and at the moment the upper die 1 and the lower die 2 are separated, the rigid body 6 receives the force of the spring 7 and pushes out the processed stamper from the upper die 1.
It remains in "2" of the lower mold 2.
