The invention relates to a punching die. The punching die comprises an upper die, a lower die and a die core. A punch pin is fixed to the upper die. The die core comprises a die core body provided with a die cavity. A mounting shank is connected to the die core body. The lower die is provided with a fixed base used for fixing the mounting shank. Through the punching die, appropriate punch pins anddie cores can be selected according to different types of part structures to carry out punching on the parts. The parts can be fed from the front side of the die, and the punching die can carry out punching on circular tube parts. The parts can be fed from the side face of the die, and the punching die can carry out punching on long sectional material parts (such as steel angles and C-shaped steel). The die core can be replaced just by opening the mounting shank. The punching die is convenient to operate. The replacement efficiency of the die core is high. The production cost is reduced. 本发明涉及一种冲孔模具。该冲孔模具包括上模、下模和模芯，所
