PURPOSE: To improve the productivity by forcibly and automatically removing end materials produced by pierce-cutting in a pierce-cutting device of a molding pierce-cutting many through holes on the molding.

CONSTITUTION: A press die is constituted of an upper die 30 and a lower die 40, a cut mechanism 50 is provided on the lower die 40, and an ejector mechanism 60 forcibly removing end materials is provided on the upper die 30. The ejector mechanism 60 is driven after die clamping and pierce-out machining, and the end materials produced when through holes are formed on a molding are ejected downward by ejector pins 63 and automatically removed to the outside throughout cutting edges 51 and support members 52.
