PROBLEM TO BE SOLVED: To provide a method for producing a good foamed molding by simply and surely preventing the retention of air around a part where an opening is to be formed. SOLUTION: In a method for producing a foamed molding in which a core 40 is arranged on the surface 22 of an upper mold, a skin 30 is arranged on the surface 12 of a lower mold, a foaming raw material P is injected, and the material P is made to flow between the skin 30 and the core 40 and packed to form a foam in which the material P is integrated with the skin 30 and the core 40, projections 25 are formed on the mold surface where the film F of the opening 45 of the core 40 is positioned and/or on the mold surface where the recessions 35 of the skin 30 are positioned, the film F is made to adhere to the backs 36 of the recessions 35 of the skin 30 in the shape of a ring with the downstream side in the flow direction of the material P opened to perform the flow and packing of the material P. |
