摘要： PROBLEM TO BE SOLVED: To prevent generation of projections on the surface of a hose caused by invasion of rubber into intake vents formed on the inner mold and the outer mold when a bellows rubber hose is molded by drawing a vacuum from occurring, by applying a specified structure to these intake vents.
SOLUTION: In a method for molding the bellows rubber hose in which on the outer periphery of the inner mold in which a hollow hole exists at the center, a bellows part is formed on the outer periphery, a straight cylinder part 7 is formed on both sides thereof, and a vent hole making the hollow hole communicate with the outside is formed, a straight cylinder rubber hose is tightly inserted, and the bellows part is formed on the straight cylinder rubber hose by sucking air from the hollow hole, an air-permeable raw material 9 for preventing the rubber from invading fills the vent hole.
