PURPOSE: A press mold apparatus for bending a pipe is provided to maintain a hypocenter of the cross section of an exhaust pipe which is bent, to exhaust gas at a constant speed, and to mold the exhaust pipe having a constant curvature using one compression without an expensive bending machine. CONSTITUTION: A press mold apparatus(100) for bending a pipe comprises a lower bed(110), a lower mold(120), an upper mold(140), a guide unit(150), a pair of jigs(160) for maintaining shape, and a support stand(170). The upper mold pressurizes a base material(M). The base material is bent in the shape of a molding surface. The guide unit guides the upper mold to be vertically ascended and descended. The jigs maintain a cross-sectional shape of the base material in a pressure molding. The support stand fixes the jig on both sides of the lower mold.
