TIRE VULCANIZING APPARATUS

摘要

An apparatus for vulcanizing a tire comprises: a side mold segment provided with a face for shaping the outer surface of a tire sidewall portion, and an opposite face not serving for shaping; and a heater part for vulcanizing the raw tire. The heater part is disposed adjacently to the side mold segment to heat the raw tire abutting on the side-shaping-face from the side of the face not serving for shaping. The side mold segment is provided with a flow path through which a first fluid whose temperature is lower than the vulcanization temperature of the raw tire can flow to prevent over-vulcanization of the sidewall portion.

1. An apparatus for vulcanizing a tire comprising:
a side mold segment provided with a side-shaping-face for shaping the outer surface of a sidewall portion of the tire, and a face being opposite to the side-shaping-face and not serving for shaping, and a heater part for vulcanizing the raw tire, the heater part disposed adjacently to the side mold segment to heat the raw tire abutting on the side-shaping-face from the side of the face not serving for shaping, wherein the side mold segment is provided with a flow path comprising a supply port portion for being supplied with a first fluid whose temperature is lower than the vulcanization temperature of the raw tire, a discharge port portion for discharging the first fluid, and a main portion extending between the supply port portion and the discharge port portion.
