The invention discloses a turret of an injection blow molding machine, comprising a triangular turntable and a plurality of mandrels, grooves and first long grooves connecting the grooves are respectively arranged on three side surfaces, a cylinder sleeve is arranged in each groove, a piston is arranged in each cylinder sleeve, a first push plate is arranged in each first long groove, the first push plate abuts against each piston on the same side surface, a plurality of air supply holes are arranged on the bottom surface of the turntable, air passages communicated with the air supply holes one by one are arranged in the turntable, the air passages extend to the bottom surfaces of the grooves and are communicated with the inside of the cylinder sleeves, mandrel seats are detachably arranged on the three side surfaces of the turntable respectively, mandrel mounting holes opposite to the first long grooves are arranged on the mandrel seats, the mandrels are fixedly arranged in the mandrel mounting holes, and the tail ends of the mandrels abut against the first push plates. When the mandrels need to be replaced, the mandrel seats and the mandrels only need to be detached together, then new mandrels and mandrel seats are replaced, and the new mandrel seats are installed on the side surfaces of the turntable, thus improving the convenience of mandrel replacement.
