摘要： A metal die device for casting of a simpler device structure by which a cast product having an undercut may directly be produced is disclosed. A casting (cavity) S is provided between a fixed die 21 and a movable die 31 as a movable core 40 having an undercut forming projection 41 is interposed between the fixed and movable dies. A swing member 54, caused to swing by a cylinder 51, is provided overlying the movable die 31. On the swing member 54, there is provided a cylinder 57 for vertically sliding the core 40. In die opening, following casting, the core 40 is vertically slid and subsequently caused to swing towards an upper outer side to release the core 40 from the cast product. Degree of freedom in metal designing is achieved without excess restriction in the shape or position of the undercut.
