Patent ID: 8568120

Claim:
A tire vulcanization mold manufacturing method of manufacturing a tire vulcanization mold onto which a surface of a gypsum mold is transferred, the tire vulcanization mold manufacturing method comprising: positioning at least one tubular body having a slit through which a hollow interior of the tubular body communicates with an outside such that a portion of the tubular body defining the slit contacts the surface of the gypsum mold, the tubular body extending longitudinally along the surface of the gypsum mold so that the slit that extends along the tubular body is exposed; providing molten metal onto the surface of the gypsum mold in such a way that the tubular body is buried in the molten metal while the slit remains exposed from the molten metal; and solidifying the molten metal to form the tire vulcanization mold such that the slit remains exposed at a tire molding surface of the tire vulcanization mold.
