To eliminate a malfunction which occurs accompanied by the molding of a negative angle part, and to improve the quality of appearance, in a press molding mold.SOLUTION: A press molding mold 1 for press-molding a roof panel having a negative angle part comprises: a processing cam 21 having a curved blade 26; a rear lower cam 22 having a negative angle forming part 27 for forming a negative angle part at a workpiece 20 together with the curved blade 26 by receiving the processing cam 21; a pad 23 having a pressing face 50 for pressing the workpiece 20 between a rear-edge support molding face 33 for forming the negative angle forming part 27 and itself; and a lateral lower cam 24 having a support face 43 for supporting the workpiece 20 while opposing the pressing face 50 together with the rear-edge support molding face 33. The rear lower cam 22 has a movable mold part 71 which is movably arranged in a direction approximate to the lateral lower cam 24, and a fixed mold part 72 having a molding face 73 continuous to the rear-edge support molding face 33 and the support face 43, and arranged at a fixed position with respect to the lateral lower cam 24 in the direction.SELECTED DRAWING: Figure 7
【課題】プレス成形型において、負角部の成形にともなって生じる不具合を解消し、外観品質を向上させる。【解決手段】負角部を有するルーフパネルをプレス成形するためのプレス成形型1であって、寄曲刃26を有する加工カム21と、加工カム21を受けて寄曲刃26とともにワーク20に負角部を形成する負角形成部27を有する後下カム22と、負角形成部27をなす後縁支持成形面33との間にワーク20を押さえる押圧面50を有するパッド23と、後縁支持成形面33とともに押圧面50に対向してワーク20を支持する支持面43を有する横下カム24と、を備え、後下カム22は、横下カム24に対して近付く方向に移動可能に設けられた可動型部71と、後縁支持成形面33および支持面43と連続する成形面73を有し、横下カム24に対して前記方向について固定の位置に設けられた固定型部72と、を有する。【選択図】図7
