PURPOSE: A system is provided to enable energy saving operation by restricting the operation of a hydraulic unit during vulcanization in which a machine is stopped. CONSTITUTION: A hydraulic system for the vulcanization of a tire in which various hydraulic cylinders of tire vulcanizing machines(9-13) are connected to a hydraulic unit(2) for supplying oil of a prescribed pressure by a hydraulic line is provided with one or more tire vulcanizing machines(9-13), the hydraulic unit(2), an accumulator circuit(3) which accumulates pressure oil from the unit(2) and supplies it to various hydraulic cylinders, and non-return means(4-8) which are fitted to each of the vulcanizing machines(9-19) so that the pressure oil of the hydraulic unit(2) and the circuit(3) is intercepted during the operation of the vulcanizing machines(9-13) and the interception is relieved to pass the pressure oil of the unit(2) and the circuit(3) during the operation of the vulcanizing machines(9-13).
