Abstract
A tire vulcanizing press of the present invention uses a split die device having an upper disk to which an upper die portion for molding the tire side is attached, a lower disk to which a lower die portion for molding the tire side is attached, divided segments to which a split tread die portion for molding the tire tread is attached, and an outer ring which has an inner inclined surface corresponding to the outer inclined surface of the segment and are slidably engaged with the outer inclined surface. Each of the divided segments has protrusions at the upper part and the lower part so that outward forces applied to the die portions during vulcanization are received by the protrusions of the segments.
