Summary:To heighten productivity, and to lower cost, by reducing man-hours for shape correction of a die.SOLUTION: Press molding analysis is performed by using mold models 1, 2 having low elasticity regions 7, 8 each having a lower Young's modulus than a press-molded product model W, to thereby insert the press-molded product model W into low elasticity regions 7, 8 of the mold models 1, 2. The shape of the mold models 1, 2 is corrected based on a deformation volume of the low elasticity regions 7, 8 of the mold models 1, 2 caused by insertion of the press-molded product model W.SELECTED DRAWING: Figure 3 【課題】金型の形状修正の工数を削減して、生産性を高めて低コスト化を図る。【解決手段】プレス成形品モデルＷよりもヤング率の低い低弾性領域７，８を有する金型モデル１，２を用いてプレス成形解析を行うことで、プレス成形品モデルＷを金型モデル１，２の低弾性領域７，８にめり込ませる。このプレス成形品モデルＷのめり込みによる金型モデル１，２の低弾性領域７，８の変形量に基づいて、金型モデル１，２の形状を修正する。【選択図】図３
