Abstract
The utility model discloses a precision cutting mold for precision cutting of tooth profile and cutoff of trimmings of a forge piece which is forged with tooth profile previously and remained with prevision cutting allowance. The precision cutting mold of a plate hub comprises an upper mold with a push block, a lower mold matched with the upper mold and used for holding the plate hub, and a knock-out pin acting on the push block, wherein a through hole is formed in the middle position of the upper mold; the push block is arranged in the through hole; and the push block is provided with a groove matched with the shape of the plate hub in relation to the position for holding the plate hub on the lower mold. With such a structure, for precision cutting of tooth profile and cutoff of trimmings of the forge piece which is forged with tooth profile previously and remained with prevision cutting allowance, consequent machining is avoided, the production efficiency is improved, the production cost is reduced and the requirements of large-batch production are met.
