Method for producing skin-covered foamed molded article and apparatus for producing thereof

A method for producing a skin-covered foamed molded article, the method comprising:

• blow-molding a parison in a mold cavity to form a hollow molded body to be a skin, in which the parison is in softened state as formed by extruding a thermoplastic resin in molten state using an extruder;
• filling the thermoplastic resin expanded beads in the hollow molded body;
• and
• heating and fusion bonding the expanded beads by supplying steam via a steam supply pipe inserted into the hollow molded body, wherein
• the parison is in contact with a protruding portion which is formed by protrusion from inner surface of the mold cavity to inside of the cavity, to form a recessed portion having a shape corresponding to the shape of the protruding portion in the inward direction of the hollow molded body,
• a hole for inserting a steam supply pipe is formed in the recessed portion,
• a steam supply pipe is inserted into the hollow molded body, and
• the expanded beads are heated and fusion bonded by supplying steam from the steam supply pipe inserted into the hollow molded body.
