The invention discloses a punching device for mold production. The punching device comprises a base plate, a transverse adjusting device, a longitudinal adjusting device, a clamping device, a supporting plate, a lifting device, a mounting plate, a driving device, a cooling device and a rotating device; and the base plate is internally provided with the transverse adjusting device, the transverse adjusting device is fixedly connected with the base plate, the top of the transverse adjusting device is provided with the longitudinal adjusting device, and the longitudinal adjusting device is fixedly connected with the transverse adjusting device. According to the punching device for mold production, the transverse adjusting device and the longitudinal adjusting device can be used for processinga plurality of holes at a time, the position of a mold plate does not need to be moved again, processing time is saved, and the processing efficiency is improved; the cooling device is used for cooling a drill bit and the mold plate, and the processing precision of mold plate holes is improved; and an air cylinder is used for clamping the mold plate, the clamping method is more rapid, the mold clamping time is shortened, the processing efficiency is improved, the air cylinder achieves clamping more firmly, and accurate punching is further ensured.
