Abstract:
1. A tire vulcanizing mold manufacturing method of manufacturing a mold to which a surface of a plaster mold is transferred by pouring molten metal over the surface of the plaster mold and solidifying the molten metal, characterized in that the method comprises the steps of: arranging a tubular body formed by oppositely arranging inner peripheral surfaces of both end portions of a plate-shaped body, in such a way that a gap between the both opposite end portions thereof is narrowed and that tips of the both end portions come in contact with the surface of the plaster mold, by inserting and fitting the both opposite end portions into a fitting portion of a plate-shaped metal fitting protruding from the surface of the plaster mold; pouring the molten metal over the surface of the plaster mold to embed the tubular body in a mold while exposing the tips of the both opposite end portions at a tire molding surface of the mold; and removing the metal fitting from the mold, so that a mold having a small gap between the both opposite end portions is manufactured.
