Abstract
The invention provides a finishing die which comprises a female die and a punch. A female die cavity is formed in the female die, and the punch is located below the female die cavity. An elastic discharging device is located above the female die and arranged around the female die cavity, and the elastic discharging device stretches into or gets away from a cavity opening of the female die cavity in the horizontal direction of the upper die face of the female die. Compared with the prior art, the elastic discharging device is added to the upper face of the finishing female die and used for supporting the bottom of a forge piece, so that the forge piece does not make contact with the finishing female die in the discharging process, the galling phenomenon of the opening portion of the finishing female die is avoided, and the service life of the finishing die is prolonged; the size change, caused by discharging force, of the opening portion of the forge piece is also avoided, and therefore the rejection rate of products is lowered.
