The invention discloses an injection blow-molding machine rotation tower which comprises a triangular turntable and a plurality of core rods. Grooves and first long grooves for connecting the grooves are respectively formed in three side faces, cylinder sleeves are arranged in the grooves, pistons are arranged in the cylinder sleeves, first pushing plates are arranged in the first long grooves, the first pushing plates abut against the pistons on the same side face, a plurality of air supply holes are formed in the bottom surface of the turntable, air ways communicated with the air supply holes in a one-to-one correspondence mode are formed in the turntable, extend to the bottom surfaces of the grooves and are communicated with the insides of the cylinder sleeves, core rod seats are respectively and detachably arranged on the three side faces of the turntable and are provided with core rod installing holes opposite to the first long grooves, the core rods are fixedly arranged in the core rod installing holes, and the tail ends of the core rods abut against the first pushing plates. When the core rods are needed to be replaced, only the core rod seats and the core rods are dismounted together, then new core rods and core rod seats are mounted, the new core rod seats are installed on the side faces of the turntable, and the convenience of core rod replacement is improved.
