Abstract:
1. A resin molding method for molding a resin molded product by injecting a molten resin into the cavity of a metal mold followed by solidification, the method comprising: providing a stepped part which changes a molded product shape from a thin part to a thick part in said cavity; providing an outside air inlet part which is formed on said metal mold and is opened to said stepped part in said cavity or an inner wall of said cavity which forms said thick part of said molten resin to allow an outside of said metal mold to communicate with an interior of said cavity; injecting said molten resin into said cavity so as to flow orthogonally to said stepped part to form said thin part to said thick part of said molten resin with said stepped part as a boundary; and forming sinks on said molten resin by being in contact with an outside air via said outside air inlet part.
