Zusammenfassung:To provide a press-molding device that can deal with speed-up in press molding cycle and can be simply structured to achieve low cost.SOLUTION: A press-molding device 1 comprises: a pad lock part 42 that moves integrally with a pad 32 and forms a gap between a blank holder 23 and the part in a state where the pad 32 holds a work-piece W together with a punch 21; and a locking unit 5 that intrudes into the gap between the pad lock part 42 and the blank holder 23 when released from a mold and holds a positional relation between the pad 32 and the blank holder 23 until the pad 32 is separated from the work-piece W.SELECTED DRAWING: Figure 7G 【課題】プレス成形サイクルの高速化に対応できるとともにシンプルな構造で低コスト化を実現できるプレス成形装置を提供すること。【解決手段】プレス成形装置１は、パッド３２とともに一体的に移動し、パッド３２がパンチ２１とワークＷを挟持する状態でブランクホルダ２３との間に隙間を形成するパッドロック部４２と、離形時に、パッドロック部４２とブランクホルダ２３の間の隙間に入り込み、パッド３２がワークＷから離間するまでパッド３２とブランクホルダ２３の位置関係を保持するロッキングユニット５と、を備える。【選択図】図７Ｇ
