Abstract
A hydraulic system for a tire curing press includes at least one tire press operated by a hydraulic cylinder and a hydraulic control valve; a hydraulic unit for supplying pressure oil of a fixed pressure; an accumulator circuit for accumulating pressure oil from said hydraulic unit to supply the accumulated pressure oil to the hydraulic cylinder and the hydraulic control valve; and a check valve provided on every tire press. The check valve cuts off pressure oil from the hydraulic unit and the accumulator circuit during vulcanization of the tire press. Thereby, it is possible to limit the operation of the hydraulic unit during the vulcanization which results in energy saving operation.
