    • PROBLEM TO BE SOLVED: To provide a stamping molding method which prevents occurrence of burrs in a stamping molded article, and does not adopt a conventional share edge part. SOLUTION: When clamping molds by making an upper mold 2 approach a lower mold 1 from a mold opening state P in which the upper mold 2 provided with a pressing mold 3 and a support mold 4 and the lower mold 1 having a workpiece 9 made of fiber reinforced resin or else softened by heating so as to have fluidity, being mounted thereon are opened, at first the support mold 4 is directly brought into close contact with the lower mold 1 by closing surfaces 10, 11 between the upper mold and lower mold on the outer periphery of the article 9 on the lower mold 1, a working mold 3 is caused to slide along guide surfaces 7, 8 for the support mold 4 toward the lower mold 1, the workpiece 9 in a molding chamber 12 formed to be closed between the upper mold 2 and the lower mold 1 is pressed by the pressing mold 3 and, thereby, the workpiece 9 is charged to a fluid chamber 13 remaining between the workpiece 9 and the closing surfaces 10, 11 to manufacture the molded article 20 of stamping molding in the molding chamber 12, wherein an edge 14 exposed to the fluid chamber 13 on the closing surface 11 of the support mold 4 and an edge 17 exposed to the fluid chamber 13 on the closing surface 10 of the lower mold 1 are directly brought into close contact with a form surface of the molded article 20 itself of stamping molding. As the result, the stamping molding mold preventing a molded article of stamping molding from being burred is provided. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供一种冲压成型方法,其防止冲压成形品发生毛刺,并且不采用常规的共用边缘部。 解决方案:通过使上模具2从模具打开状态P接近下模具1而夹紧模具,其中上模具2设有加压模具3和支撑模具4,下模具1具有工件 9由纤维增强树脂制成,或者通过加热软化以便具有流动性,安装在其上,首先,支撑模具4通过在上模具之间的闭合表面10,11直接与下模具1紧密接触 在下模具1上的制品9的外周上的下模具,使工作模具3沿着用于支撑模具4的引导面7,8朝向下模具1滑动,工件9在成型室12 形成为在上模2和下模1之间形成的密封被压模3按压,从而工件9被填充到残留在工件9和封闭表面10,11之间的流体室13中, 冲压成型的模制品20 在成型室12中,其中露出到支撑模具4的封闭表面11上的流体室13的边缘14和暴露于下模具1的封闭表面10上的流体室13的边缘17被直接进入 与模制品20本身的成型表面紧密接触的冲压成型。 结果,提供了防止冲压成型的模制品被烫伤的冲压成型模具。 版权所有(C)2010,JPO&INPIT
