イプの製造装置。 An endless split mold for forming an outer peripheral wall, which has a semicircular cross-sectional shape and an uneven surface on the inner peripheral surface, is aligned so that the resin extrusion part of the extrusion molding machine is wrapped around the inner periphery, and the mold is aligned in the extrusion direction of the resin. arranged to be driven;
The resin extrusion section includes a first annular nozzle for extruding resin onto the inner peripheral surface of the split mold to form an uneven outer peripheral wall of the pipe; and a first annular nozzle for extruding resin onto the inner peripheral surface of the uneven outer peripheral wall to form an inner peripheral wall of the pipe. A cooling section in which a refrigerant is circulated is provided at the tip of the resin extrusion section, and a lubricant is supplied between the cooling section and the inner circumferential wall of the pipe. This is a double-walled pipe manufacturing device that has a lubricant discharge port provided at the tip of a resin extrusion section.
