Abstract: A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.

Abstract translation: 一种皮肤覆盖的发泡成型体的制造方法，其特征在于，在模腔内形成型坯，形成由中空成型体构成的皮肤，所述型坯通过挤出熔融热塑性树脂处于软化状态， 中空成型体中的小珠，并且通过插入中空成型体中的蒸汽供给管供给蒸汽来加热熔融粘合珠粒。 型坯与从模腔的内表面突出到空腔的内部的突出部分接触，形成与中空成型体的向内方向上的突出部分相对应的形状的凹部。 在凹部形成蒸汽孔，将蒸汽供给管插入体内，通过供给蒸汽对发泡珠进行加热熔合。
