The present invention discloses a synchronous mold opening/closing and lifting mechanism for an injection blow molding machine, comprising a mold opening and closing oil cylinder and a connecting rod which are connected with each other. The two ends of the connecting rod are respectively connected with a blow molding tie rod shaft and an injection tie rod shaft. The other end of the blow molding tie rod shaft is connected with a blow molding movable mold plate, and the other end of the injection tie rod shaft is connected with an injection movable mold plate. A connecting arm is hinged on the injection movable mold plate, a lifting shaft is arranged in the middle of the connecting arm, and the other end of the connecting arm is connected to the crossbeam through a lifting oil cylinder. One end of the lifting shaft is vertically connected to the turret, a groove surrounding its outer wall is arranged at the other end, and a bearing which is rollingly embedded in the groove is arranged in the middle of the connecting arm. The mold opening and closing oil cylinder indirectly drives the blow molding movable mold plate and the injection movable mold plate to move synchronously through the connecting rod, and the movement of the injection movable mold plate drives the connecting arm to move, indirectly driving the turret to move, thereby realizing synchronous operation of mold opening and closing of the injection mold and the blow mold as well as lifting of the turret.
