ABSTRACT:
Disclosed is a center mechanism of a tire curing press which is capable of easy installation and removal of a bladder assembly. The center mechanism comprises the bladder assembly with the upper and lower ends of a bladder supported with upper and lower support members, a piston rod vertically moving into, and out of, engagement with the upper support members, and a lift cylinder vertically moving into, and out of, engagement with the lower support members. In this center mechanism, there is provided a stepped projecting section formed large in diameter in the upper part and small in diameter in the lower part; the upper support members can easily be installed to, and removed from, the upper end of the piston rod by the use of a stepped block which engages the stepped projecting section and is horizontally divided into a plurality of segments, and a restricting member for restricting the horizontal movement of the stepped block, thereby enabling easy installation and removal of the bladder assembly.
