A spiral bevel gear forging apparatus for forging a blank includes a first mold core having a mold cavity for receiving the blank, a first punch rod inserted movably into the first mold core and having a positioning end extending into the mold cavity for releasable engagement with a bottom of the blank, at least one push mechanism, and a drive mechanism. When the drive mechanism is operated to move from a non-ejecting to an ejecting position, the push mechanism is actuated to drive the first mold core to rotate about the first punch rod, and the first punch rod is actuated to move relative to the first mold core such that the positioning end thereof is moved out of the mold cavity for ejecting the blank out of the first mold core.

Spiral bevel gear forging apparatus

A mold set for manufacturing a case is provided. The mold set comprises an upper mold having a fluid channel; a lower mold facing the upper mold; and a drawing mold disposed between the upper mold and the lower mold, wherein the mold set has a case forming space formed among the upper mold, the lower mold and the drawing mold, and the mold set has a sharp-edge forming space communicating with the case forming space, and formed between the drawing mold and the lower mold.
