PROBLEM TO BE SOLVED: To provide a resin molding implement and a resin molding method for molding a resin material easily.SOLUTION: Into a silicone-resin-made molding die 10 the shape of whose inner surface has the shape of an outer surface of a resin molding 30 and which is opened partially, a balloon-like core 20 which becomes in a shrunk state at ordinary temperature, expands when heated, is to be inserted from the opened part of the molding die 10, changes its shape of the outer surface to the shape of the inner surface of the resin molding 30 when expanded by heating and is sealed in a condition that a gas is injected is inserted from the opened part of the molding die 10, and a resin material is injected into a space formed by the inside surface of the molding die 10 and the outer surface of the core 20. The whole body of the molding die 10 and the core 20 injected with the resin material is heated in a heating oven 40 to mold the resin material into the resin molding 30, and the heated whole body of the molding die 10 and the core 20 injected with the resin material is cooled until the core 20 is shrunk to remove the shrunk core 20. Then, the resin molding 30 is taken out from the molding die 10. |
