Tire vulcanizing method and device

Abstract

A tire vulcanizing method comprises: a step of causing a connecting body, at which an upper mold of a vulcanization mold is supported and that connects together upper end portions of upper tubes of a plurality of supporting pillars, the supporting pillars being disposed so as to be apart in a peripheral direction at a periphery of the vulcanization mold, which is formed from a lower mold and the upper mold, which is set above the lower mold, and the supporting pillars having lower tubes that are hollow and the upper tubes, which are hollow and are slidably engaged with the lower tubes, and the supporting pillars extending in a vertical direction, to, together with the upper tubes and the upper mold, approach the lower mold, and close the vulcanization mold; and a step of vulcanizing an unvulcanized tire that is accommodated at an interior of the vulcanization mold that is closed, wherein the causing the connecting body, the upper tubes and the upper mold to approach the lower mold is carried out by operating raising/lowering mechanisms that are accommodated at interiors of the supporting pillars.
