The invention provides a multi-station hydraulic cylinder interlocking and hydraulic cylinder oil supplementing and oil draining mechanism. The mechanism comprises a first double-effect upper oil cylinder, a second double-effect upper oil cylinder, a first double-effect lower oil cylinder and a second double-effect lower oil cylinder. A rod cavity of the first double-effect lower oil cylinder and a rod cavity of the first double-effect upper oil cylinder are connected with a first oil opening of a hydraulic converter. A rodless cavity of the first double-effect upper oil cylinder and a rodless cavity of the second double-effect lower oil cylinder are connected. A rodless cavity of the first double-effect lower oil cylinder and a rodless cavity of the second double-effect upper oil cylinder are connected. A rod cavity of the second double-effect upper oil cylinder and a rod cavity of the second double-effect lower oil cylinder are connected with a second oil opening of the hydraulic converter. By means of the multi-station hydraulic cylinder interlocking and hydraulic cylinder oil supplementing and oil draining mechanism, the movement requirements for the synchronous movement, interlocking and the like of the oil cylinders can be well met, the oil cylinders are provided with the oil supplementing and oil draining mechanism so that unnecessary pipelines and some electric appliance switch elements can be saved, the movement precision of the oil cylinders can be higher, reliability is higher, and maintenance is convenient.
