The invention belongs to an integral type hinge beam closed-die forging and pressing forming die and a hinge beam manufacturing method. The integral type hinge beam closed-die forging and pressing forming die comprises a mold punch connected to a pressing machine sliding block, a shaping female mold and an ejection block arranged at the inner bottom of the shaping female mold, wherein the mold punch comprises an upper mold base connected to the pressing machine sliding block, a male mold connected to the upper mold base and a piercing puncher chip arranged in the upper mold base and passing through the male mold; the forming female mold is of a top-to-bottom through hole structure, and the shape of the cavity of the interior of the forming female mold is matched with a hinge beam; and the ejection block is movably arranged at the inner bottom of a through hole of the forming female mold. The integral type hinge beam closed-die forging and pressing forming die has the advantages of one-time heating, closed-die hot extrusion forming, compacted and impregnable four lug parts of a workpiece, guaranteed product quality, small allowance for machining, high utilization rate of materials, high production efficiency and low production cost.
