    摘要： A process for producing a skin material-laminated hollow molded article of thermoplastic resin, using a mold having, in any one or both of its fixed and movable parts, at least one fluid-ejecting pin which can be slid in a clamping direction and which has a fluid-ejecting hole at its pointed end. The process consists of fixing two sheets of a skin material having a tensile modulus at ambient temperature of 50-1,000 kg/cm.sup.2 and a tensile modulus at 80.degree. C. of 5 to 100 kg/cm.sup.2 on the parting surfaces of both the mold parts which are in the open state. A molten thermoplastic resin is fed between the skin materials in an amount of 5 to 50% by volume of the cavity volume. The fluid-ejecting pin is thrusted so that its pointed end penetrates one of the skin material sheets and comes between the skin material sheets. The mold parts are closed to wrap the molten thermoplastic resin in between the skin material sheets. A fluid is ejected from the fluid-ejecting hole to intimately contact the skin material sheets with the cavity surface of the mold while allowing the molten resin to form a hollow. The mold is cooled and the ejection of the fluid is stopped. The mold is then opened and the hollow molded article is removed.

    摘要： The present process includes a mold for producing a thermoplastic resin molded article, comprising paired sliding female and male mold members, which mutually slide at the time of mold closing. A product-forming portion and a non-product-forming portion are provided in the cavity of the mold, the mold further including a resin-supplying opening. A gate portion located at a boundary between the product-forming portion and non-product-forming portion interconnects the two portions. At closing of the mold, the width of the gate at the product-forming side is less than the thickness of the formed product, and stepwise or continuously widens toward the non-product-forming side. Using this mold, a thermoplastic resin molded article, with or without a laminated skin material, can be molded in good efficiency and low cost, further having a non-product-forming portion, which can be readily trimmed from the product-forming portion.
