Abstract
A center mechanism for a tire mold comprising a mushroom-shaped bladder, a clamp ring for clamping a lower opening edge of the bladder, a post cylinder for extending and contracting a height of the bladder, a movable stopper for receiving a depressing force against the clamp ring which is generated by heating medium introduced into the bladder upon vulcanizing a tire, and a bladder elevator cylinder for elevating and lowering the clamp ring upon loading and unloading a tire.
