Stamping die with self-cooling function

The utility model discloses a stamping die with a self-cooling function, which comprises a base, a vertical plate is fixedly connected onto the base, a top plate is fixedly connected onto the vertical plate, an air cylinder is fixedly connected onto the top plate, an output end of the air cylinder is fixedly connected with a fixing plate, a punch is in contact with the fixing plate, and the punch is fixedly connected onto the base. And a mold seat is arranged on the base. By designing the liquid inlet pipe, cooling liquid can be input into the fixing plate, the fixing plate can be cooled by the cooling liquid, the purpose of cooling the punch can be achieved, when punching is carried out under the action of the air cylinder, the liquid discharging pipe can be inserted into the connecting groove, and therefore the punch can be conveniently punched. The die base can be cooled through flowing of cooling liquid in the flow channel, the punch and the die base can be prevented from being overheated in the punching
