description To provide a manufacturing method of a molding member having a simple manufacturing step and providing the long life and an excellent cooling effect.SOLUTION: A manufacturing method of a steel molding member (draft pin 1) having a cooling hole in the inside includes: a filling step of filling the cooling hole with a metal material having a lower melting point than the molding member; a heat treatment step of heat-treating the molding member filled with the metal material at a temperature between a melting point of the molding member and a melting point of the metal material, and joining the melted metal material to the inner surface of the molding member; and an excavating step of excavating a solidification part obtained by cooling to solidify the melting metal material, and forming a protection part 8 for coating the inner surface of the molding member.SELECTED DRAWING: Figure 2 【課題】製造工程が簡易で、寿命が長く冷却効果に優れる成形用部材の製造方法を提供する。【解決手段】内部に冷却穴を有する鋼製の成形用部材（鋳抜きピン１）の製造方法であって、冷却穴に成形用部材よりも融点が低い金属材を充填する充填工程と、金属材が充填された成形用部材を、成形用部材の融点と金属材の融点の間の温度で熱処理して、溶融した金属材と成形用部材の内面とを接合させる熱処理工程と、溶融した金属材が冷却固化した凝固部を掘削して成形用部材の内面を被覆する保護部８を形成する掘削工程と、を含む。【選択図】図２
