FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in dies for making complex-shape forgings. Die includes top and bottom parts provided with top and bottom die bed contours and limiting ledges made on edges of said contours. Ledge inner surface are provided with bed contours producing, together with said top and bottom contours, an integrated closed surface along forging edges. Die top and bottom parts may joint together along ledge side surfaces. Note here that forging lateral projection contour does not cross lateral projection of die opening plane in the same direction. Surfaces of top and bottom die bed contours may be arranged at angle to horizontal plane.
EFFECT: higher precision of forgings, simplified withdrawal of forgings.
