The invention relates to the field of tire forming, and discloses an integrated hydraulic system and a tire vulcanizing machine. The integrated hydraulic system comprises a hydraulic pump source, a control valve block and an executing mechanism, the executing mechanism comprises an integrated oil cylinder and a liquid filling unit, the integrated oil cylinder comprises a cylinder body, a static piston rod and a movable piston rod, the static piston rod is fixedly arranged in the cylinder body, the movable piston rod is arranged in the cylinder body in a sliding mode and matched with the static piston rod in a sliding mode, a rodless cavity and a rod cavity are formed between the movable piston rod and the cylinder body, a fast forward cavity is formed between the movable piston rod and the static piston rod, the liquid filling unit is used for supplying hydraulic oil to the rodless cavity, and the hydraulic pump source supplies the hydraulic oil to the rod cavity, the rodless cavity and the fast forward cavity through a control valve block. The system is compact in structure, reduces the occupied space, is simple and convenient to install, improves the working efficiency, provided with few pipeline connecting points, is low in leakage probability of the hydraulic oil, realizes quick die assembly without additionally outputting flow by an oil pump, reduces the cost and energy consumption, and reduces noise.
