The invention discloses a turret rotating device of an injection blow molding machine, comprising a shaft seat, a lifting support seat and a driving motor which are arranged on the lower surface of a table panel of the injection blow molding machine. A rotating arm is rotatably connected in the shaft seat, a mandrel is arranged in the rotating arm, a lifting oil cylinder is arranged on the lifting support seat, a lifting bearing seat is connected to the end of a push rod of the lifting oil cylinder, the upper end of the mandrel is fixedly connected with the turret, the lower end is rotatably connected in the lifting bearing seat, three rotation detection rods are uniformly distributed in the circumferential direction at the lower end of the mandrel, a rotation detection proximity switch is arranged on the outer wall of the lifting bearing seat and opposite to one rotation detection rod, and the driving motor and the rotation detection proximity switch are electrically connected with a control system of the injection blow molding machine respectively. When the driving motor drives the turret to rotate one station, another rotation detection rod is opposite to the rotation detection proximity switch, and the rotation detection proximity switch sends an electric signal indicating "rotation in place" to the control system, so as to realize the function of detecting the rotation angle of the turret.
