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 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.
摘要翻译：在固定模具和可动模具闭合之前，通过在一对固定模具和可动模具之间供应熔融树脂来制造中空成型制品，插入设置在固定模具和活动模具的表面上的至少一个供气销模具在树脂的一部分中形成中空部分，并且在模具闭合完成之前通过所述气体供给销供给加压气体，关闭可移动模具以将树脂填充在由模具形成的空腔中，稍微打开模具，同时对树脂中的气体进行加压以膨胀中空部分并打开可移动模具以从模具中移除中空模制品。
