Abstract
Provided are a resin molding mold enabling an intake manifold made of a resin to be manufactured at low cost, an intake manifold, and a method for molding a resin for an intake manifold. The resin molding mold for an intake manifold includes a slide mold provided at an end of a surge tank and a plurality of combination-type core molds molding an inner surface of the surge tank. The core molds include a first core member capable of a relative movement in advance of another core member after resin molding, and a second core member capable of moving with utilizing an inner space formed by the relative movement of the first core member. The first core member and the second core member are configured to be extractable through a space inwardly of a resin-molded flange.
