Abstract
A tire vulcanizing device including: an upper annular mold attaching member and a lower annular mold attaching member that respectively attach side portion forming molds for forming side portions of a tire; a plurality of segments that respectively attach a plurality of segmented tread molds for forming a tread portion of the tire; and a mold closing mechanism for radially moving the segments to close the tread molds at an advanced end. The respective segments are respectively independently provided with heat medium passages for applying heat for vulcanization to the tread molds when supplied with a heat medium.
Claims3
A tire vulcanizing device comprising:
- an upper annular mold attaching member and a lower annular mold attaching member that respectively attach side portion forming molds for forming side portions of a tire;
- a plurality of segments that respectively attach a plurality of segmented tread molds for forming a tread portion of the tire;
- a plurality of cylinders for respectively moving the plurality of segments in radial directions to close the respective tread molds at an advanced end, each cylinder being connected to a cylinder support plate from which a prop protrudes to connect to a guide member that guides the respective segment;
- heat medium passages respectively independently provided in the respective segments for applying heat for vulcanization to the tread molds when supplied with a heat medium;
- and
- heat insulation members respectively interposed between the segments and the cylinders for preventing conduction of heat from the segments to the cylinders;
- wherein the heat medium passages are controllable in temperature on a segment-by-segment basis.
