PROBLEM TO BE SOLVED: To prevent hanging-down deformation during foaming reaction in a method for molding of a foamed resin molded product and a molding mold, in which the product is molded in a required shape by injecting and filling a foamed resin material in a cavity formed by clamping the movable side mold and fixed side mold, and then, retracting the movable side mold to induce the foaming reaction. SOLUTION: The movable side mold 50 is clamped relative to the fixed side mold 60, and the foamed resin material M is injected and filled. Then, the movable side mold 50 is retracted, and the foaming reaction is induced with a foaming space reserved to mold the door trim lower (the foamed resin molded product) 30 in this molding method. A vertical wall section 33 giving a spacial effect to this door trim lower 30 is formed, and in order to form a stepped part 34 in a lightened condition inside the front end of this vertical wall section 33, the corner angleαof the stepped part 64 of the fixed side mold 60 is set at 45°≤α≤75°, thereby centralizing the occurrence of wrinkles in the surface 34a of the stepped part and the bottom surface 35b of a thin flange 35, and favorably maintaining the appearance performance on the surface side of the product.
