    摘要： A hollow molded article is produced by supplying a molten resin between a pair of a fixed mold and a movable mold before the fixed mold and the movable mold are closed, inserting at least one gas-supplying pin which is provided on a surface of the fixed mold to form a hollow part in a part of the resin and supplying pressurized gas through said gas-supplying pin before the mold closing is finished, closing the movable mold to fill the resin in a cavity formed by the molds, slightly opening the molds while pressurizing a gas in the resin to expand the hollow part and opening the movable mold to remove a hollow molded article from the molds.

    摘要： A multilayer molded article with good appearance is produced by supplying a skin material and a melt of a thermoplastic resin between unclosed upper and lower molds and simultaneously molding the thermoplastic resin to form a molded article and laminating the skin material on a part of a surface of the molded article by pressing and cooling the thermoplastic resin in the molds, in which the lower mold has a protruding part at a position where an edge of the skin material is located, the upper mold has a depressed part at a position corresponding to the protruding part of the lower mold, and, during molding, the edge of the skin material is fixed to the lower mold by sucking it through a gap which opens at the root of the protruding part.

    摘要： A mold for compression molding a resin article, which mold consists of male and female molds, wherein, at the time of complete mold closing, the length L in a mold closing direction of a mated part formed between the outermost wall of said male mold and the innermost wall of said female mold satisfies the equation: (t1−t0+10)mm≧L≧(t1−t0)mm wherein t1 is a distance (mm) between the male and female molds when the resin melt first reaches the mating outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1 when the mold closing is complete, and the horizontal distance of a mating gap between the outermost wall surface of said male mold and the innermost wall surface of said female mold is from 0.02 to 0.1 mm, with which mold, squeeze-out of a resin melt during molding is prevented.
