Abstract

PURPOSE: To make an inner wall of a molded product smooth by a method wherein an inner mold portion for molding an undercut portion of the molded product is formed by a soft elastomer and made freely deformable in case of withdrawing.
CONSTITUTION: For example, the inner mold 1 for molding an FRP pipe joint 10 is consisted of an outer shell mold 2 and a core mold 3 inserted into the outer shell mold 2 in a freely slidable manner. After the FRP pipe 10 is molded and cured on the inner mold from a resin, a reinforcing material or the like, if the core mold 3 is withdrawn, the outer shell mold 2 made of a soft elastomer such as a rubber or a foamed plastic is easily demolded even if a protruded portion such as a ring groove 12 is formed to the FRP pipe and the smoothness of the inner wall of the molded product is maintained.
