Abstract: A forging and inclined window hole punching composite die includes an upper die holder, a connection sleeve, an upper die sliding sleeve, a pressure plate, inclined window puncher pins, a center puncher pin, first connection screw rods, first springs, second connection screw rods, second springs, hydraulic assistant systems, a lower die and a bottom plate. Bottom surface of the pressure plate of the composite die is a plane to avoid deformation of a front molding surface. Hydraulic power is added to the inclined window puncher pins to increase the pressure for punching inclined holes, avoid quality problems and increase a demolding force. A multi-split synchronous hydraulic device may well realize synchronization of the plurality of inclined window puncher pins.
