PURPOSE: A curved pipe manufacturing device is provided to reduce manufacturing costs and a failure rate by quickly and stably drawing out a curved pipe from a mold. CONSTITUTION: A curved pipe manufacturing device comprises a lower mold(100), an upper mold(200), a mandrel(300), and a pusher(400). The lower mold has an insertion path(A) for inserting a pipe material and a curved path(B) for curving the pipe material. The upper mold is formed symmetrically to the lower mold and installed to move up and down so that the bottom thereof is meshed with the top of the lower mold. The mandrel has a smaller diameter than the curved path of the upper mold and is inserted along the curvature of the curved path. The pusher is installed to move lengthwise relative to the insertion paths of the lower and upper molds and pushes a pipe material loaded in the insertion paths a curved annular gap between the curved paths and the mandrel.
