PROBLEM TO BE SOLVED: To provide a method for molding a foamed molding which can mold appropriately the foamed molding being made by bonding foam resin materials which have the same expansion ratio and belong respectively to different kinds.SOLUTION: The method for molding the foamed molding comprises: a dividing step of dividing a cavity by a partition means 21; charging step of charging a modified polystyrene resin containing polyacrylic acid alkyl ester-based resin particles or high impact polystyrene in one space S1 of the divided cavity; another charging step of charging another modified polystyrene resin or polystyrene resin having the same expansion ratio as that of the impact polystyrene resin in the other space S2 of the cavity, which space is different from the one space S1; opening step of opening the partition by the partition means 21; and a heating step of heating/molding the resins charged in the cavity while exerting the vapor pressure of 0.04-0.12 Mpa thereon. |
