Claims

[Scope of utility model registration request]

In a forging die for forging a molded product having a plurality of recesses 2 in the arc direction on a disc-shaped surface and undercut side surfaces of partition walls 3 between the recesses, the partition of the molded product is A die 14 with protrusions 16 protruding from the inner surface of the cylinder that abuts the end face of the wall 3, and a side wall on one undercut side of each partition wall 3 of the molded product 1 located between each protrusion 16 of this die 14. A ring 1 in which a protruding rod 21 to be formed protrudes in a comb-teeth shape in the circumferential direction.
9 and the protruding bar 22 which is located between the protruding bar 21 side of this ring 19 and the protruding strip 16 of the die 14 and forms the other side wall of the partition wall 3 of the molded product 1 is shaped like a comb tooth in the circumferential direction. It consists of a knockout 20 protruding from the ring 19, and a knockout device for knocking out the knockout 20, and the side surface 22a of the knockout 20 that comes in contact with the tip of the ring 19 of the protrusion 21 is undercut. The protrusion 16 of the die 14 of the protrusion bar 22 of the knockout 20 is inclined in the same direction as the slope, and a gap 24 is provided between the protrusion bars 21 and 22 below the contact portion of both protrusion bars 21 and 22. A forging die characterized in that the lower side of the part in contact with the undercut is inclined in the same direction as the slope of the undercut.
