PIPING STRUCTURE OF TIRE VULCANIZER, CIRCULATOR, AND METHOD FOR VULCANIZING TIRE WITH TIRE VULCANIZER

摘要

An example of the piping structure of a tire vulcanizer to which the present invention is applied is provided with a central mechanism 1 of the tire vulcanizer shown in FIG. 1. The central mechanism 1 is provided with a bug head 2, a water pressure cylinder 3, and exhaust circulation path pipes 4. In addition, the central mechanism 1 is provided with a bladder (not shown) allowed to expand and retract when a vulcanizing medium is supplied to the inside of the bladder. The bug head 2 has a plurality of supply ports for the vulcanizing medium and is arranged at the upper part of the central mechanism 1. One ends of the exhaust circulation path pipes 4 are connected to the inside of the bladder, and the two exhaust circulation path pipes 4 are coupled to each other via a bypass pipe 5. The other ends of the exhaust circulation path pipes 4 are connected to the outside of the central mechanism 1. Moreover, the bypass pipe 5 is fitted with a circulator 6 that circulates the vulcanizing medium while maintaining pressure inside the bladder.
