This utility model discloses a synchronous lifting mechanism between a turret and an injection blow mold in a three-station injection blow molding machine, which comprises a mold frame. A base is arranged on the mold frame, a turret is arranged on the base, and an injection mold and a blow mold are arranged on the base. The moving mold plates in the injection mold and the blow mold are respectively connected with a lower cross beam through sliding shafts, a lifting support is arranged in the mold frame in a vertically sliding manner, and a rotating shaft and a servo motor are rotatably arranged at the bottom of the lifting support. A front connecting rod and a rear connecting rod are respectively rotatably arranged on the front and rear side walls of the lifting support, a driving shaft and a driven shaft are respectively rotatably arranged between the front connecting rod and the rear connecting rod, and the driven shaft is connected with a mold adjusting mechanism. A pull rod shaft is arranged downwards on the driving shaft and connected with any one of the lower cross beams, and the two lower cross beams are connected through a linkage plate. A mold locking oil cylinder is arranged on the base, and a piston rod on the mold locking oil cylinder is connected with any one of the lower cross beams. The injection mold and the blow mold can drive the turret to lift synchronously while opening and closing the mold synchronously, which shortens the action cycle.
