摘要： PROBLEM TO BE SOLVED: To suppress the degradation of the dimensional accuracy in a plane shape of a foamed resin molding caused by the inward retreat of a molding of a molding shape profile forming end movable mold accompanying the core back operation.
SOLUTION: A packing cavity 33 is formed by a fixed mold 31, a movable mold 32, and a spacer 70, and the upper and lower surfaces 72 and 73 of the spacer 70 are held by the fixed mold 31 and the movable mold 32. In a core back process, while a foaming cell grows inside, a surface layer part 50a is formed on the surface of a molding 50. Although retreating force to make the edge of the molding 50 retreat toward the inside of the molding 50 is generated, since the edge of the molding 50 is expanded to turn to the back of the undercut part 75 of the spacer 70, the shape of the molding cavity 33 is maintained to prevent the occurrence of the retreat.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a foamed resin molded member by which, when a foamed resin molding is fitted to a mating member, the immersion of a fitting part into the body part of the molding caused by pressurization upon the fitting is avoided and the obstruction of the weight reduction of the foamed resin molding is also avoided.
SOLUTION: A foamed resin molding X is molded which includes: a molding body part Xa in which foam cells are grown by packing a foamable resin in a melted state into a molding die; and a fixing part Xb projecting from the peripheral part of an opening 80 formed at the peripheral part of the molding body part Xa and/or the molding body part Xa, and in which the growth of the foam cells is suppressed. By pressuring the fitting part Xb of the foamed resin molding X against the mating member Y, the foamed resin molding X is fitted to the mating member Y via the fitting part Xb. As a result, the reaction force of the pressurization is received by a skin layer Xc having a resin density and strength higher than those of the molding body part Xa, and the fitting part Xb is supported by the skin layer Xc against the reaction force of the pressurization.
