成されることを特徴とする鍛造型。A forging die for an inner ring of a constant velocity universal joint, in which a material is closed-forged to produce a forged molded product for an inner ring of a constant velocity universal joint by matching an upper die to a lower die, and the forging die includes the upper die and the lower die. The lower mold is composed of a bottom support insert mold that receives an axial punching load, a side support insert mold that receives a radial punching load, and a holder into which both of these insert molds are press-fitted. A forging die characterized in that a cavity corresponding to the forged product is formed by the assembly of each insert die with the lower die.
