(Operation) The tire vulcanizer of the present invention is configured as described above, and from the state where the vulcanization of the tire is completed, the hydraulic cylinder, the rod, the bladder assembly, and the vulcanizing medium inflow / outflow tube are raised. Then, the lower ring of the bladder assembly is separated from the lower mold, and then the stopper is moved directly below each nut, and then the hydraulic cylinder, the rod, the bladder assembly, and the vulcanizing medium inflow and outflow pipe are lowered to stop the nut. Contact. At this point, the lowering of the vulcanizing medium inflow and outflow pipes stops, but the lowering of the other parts, namely the hydraulic cylinder, rod and bladder assembly, continues, so that a disc spring is provided at the upper end of the hydraulic cylinder. The head of the vulcanization medium inflow / outflow tube is separated from the engagement hole provided in the lower ring of the bladder assembly by being compressed by the collar member. In this state, remove the bolts that detachably fix the upper ring and the rod of the bladder assembly, and then manually move the bladder assembly around the center axis of the tire vulcanizer within the range of the engagement hole. By rotating, the head of the vulcanizing medium inflow / outflow tube is positioned at the large diameter hole of the engagement hole, and then the bladder assembly is pulled upward. After replacing the old bladder with the new bladder, the bladder assembly is mounted in the reverse manner to complete the preparation for vulcanizing the tire.

(Effect of the Invention) The tire vulcanizer of the present invention raises a fluid pressure cylinder, a rod, a bladder assembly, and a vulcanizing medium inflow / outflow pipe from a state where vulcanization of a tire is completed as described above, and a bladder assembly. The three-dimensional lower ring is separated from the lower mold, and then the stopper is moved directly below each nut. Then, the fluid pressure cylinder, rod, bladder assembly, and vulcanizing medium inflow / outflow pipe are lowered to bring the nut into contact with the stopper. Let it. At this point, the lowering of the vulcanization medium inflow and outflow pipe stops, but the lowering of the other parts, namely the hydraulic cylinder, rod and bladder assembly, continues, so that a disc spring is provided at the upper end of the hydraulic cylinder. The head of the vulcanization medium inflow / outflow tube is separated from the engagement hole provided in the lower ring of the bladder assembly by being compressed by the collar member. In this state, remove the bolts that are detachably fixed to the upper ring and rod of the bladder assembly, and then manually rotate the bladder assembly around the center axis of the tire vulcanizer within the range of the engagement hole. Then, the head of the vulcanization medium inflow / outflow pipe is positioned at the large-diameter hole of the engagement hole, and then the bladder assembly is pulled upward. When the old bladder is replaced with the new bladder, the bladder assembly is installed in the reverse order and the tire vulcanization preparation is completed. Therefore, there is no need to remove the bladder from the housing, the time required for replacing the bladder can be reduced, and the burden on the operator can be reduced, productivity can be improved, and heat loss can be reduced.

An arcuate engagement hole is provided in a lower ring of a bladder assembly for engaging and disengaging from a head of a vulcanizing medium inflow / outflow pipe, and a fluid pressure cylinder for raising and lowering the bladder assembly can be raised and lowered at a lower portion of a base. Attachment, a bolt protruding downward from the lower end of the vulcanizing medium inflow / inlet pipe through a through hole of a flange-shaped member provided at the upper end of the fluid pressure cylinder, and a nut screwed into the lower end of the bolt. A disc spring is interposed between the flange-shaped member and a stopper located immediately below the nut when the vulcanizing medium inflow / outflow tube rises together with the bladder assembly. A tire vulcanizer, characterized in that:
