Abstract: A tire vulcanizer including: a base which supports a lower mold; a beam which supports an upper mold; a tie rod which is disposed to be fixed to one of the base and the beam on one end side thereof and has a plurality of engaged portions provided at predetermined intervals in an axis line direction along an up-and-down direction on the other end side; engaging means which is provided at the other of the base and the beam and engaged with the engaged portion of the tie rod to restrict a movement of the tie rod in the axis line direction; and pressurizing means for pressing the lower mold and the upper mold which are in a mold-closed state, so as to perform mold-clamping.

Abstract: A tire vulcanizer and tire vulcanizing system improving production efficiency by shortening time for loading and unloading of tires are provided. They include: a lower mold supporting part; an upper mold supporting part; a moving device moving the upper mold supporting part horizontally; an elevator device moving the upper mold vertically; a lift device pushing up a vulcanized tire held in the lower mold; and a tire supporting part supported by the upper mold supporting part. The tire supporting part moves between a supporting position and a retreated position. The bottom side of the vulcanized tire is supported by the tire supporting part at a peripheral side closer to the outside than a pushed-up position in the supporting position. The retreated position is positioned at a peripheral side closer to the outside than the vulcanized tire.

Abstract: The tire vulcanizer is featured by including a slide back mechanism configured such that the upper metal mold separated and lifted from the lower metal mold installed to be fixed to a base is moved by an operation of a movable carriage so as to reciprocate between a vulcanization position at which the upper metal mold is pressed toward the lower metal mold, and a waiting position at which the green tire can be carried in the lower metal mold and at which the cured tire can be carried out from the lower metal mold, and is featured in that the upper metal mold is attached below, via a squeezing cylinder mechanism, to a beam integrated with a tie rod which is vertically moved by an operation of a lifting/lowering cylinder along a guide hole provided in the movable carriage.

Abstract: To provide a tire vulcanizer which is configured to slide back a lifting/sliding mechanism to a waiting position, and which is featured in being capable of making uniform the squeezing force applied by the upper metal mold at the time of vulcanization.
