US 6,655,940 B2 · Center mechanism of tire press and tire press

Abstract

A tire press comprising a center post 22 vertically movably extended through a center part of a lower ring mechanism 12 and vertically moving an upper ring 19 with respect to a lower ring mechanism 12, a heater 103 arranged in an outer peripheral position of the center post 22 on the tire inner peripheral side of a green tire 4 held by the lower ring mechanism 12 and the upper ring 19, heater 103 to apply a heat to the green tire 4, a first driving mechanism such as a tubular member vertically moving cylinder 98 capable of vertically moving the heater 103 to a suitable height position so as to move the heater 103 to a suitable position independently of vertical movement of the center post 22, and a second driving mechanism such as a driving motor 99 capable of rotating the heater 103. By the provision of such a mechanism as described, press molding relative to a green tire 4 can be completed in a sufficiently short period of time.
