This invention relates to the field of injection blow molding machine technology, specifically an air-liquid pressurized clamping structure for an injection blow molding machine. It includes a beam, columns, and a table panel. The beam and table panel are fixed to both ends of the columns. An air-liquid booster cylinder is fixed to the upper surface of the beam. The output end of the air-liquid booster cylinder penetrates the beam, and a second-stage clamping mechanism is assembled at the output end of the air-liquid booster cylinder. The second-stage clamping mechanism includes a connecting plate, with connecting rods assembled on both sides of the connecting plate. A second-stage locking component is assembled at the end of the connecting rod away from the connecting plate. The second-stage locking component includes a movable mold plate, a pushing component, a sliding sleeve, a locking wheel, and a threaded rod. The two ends of the threaded rod are fixed to the beam and the table panel, respectively. The movable mold plate is connected to the threaded rod for lifting and lowering. The sliding sleeve is fixed on the movable mold plate, and the pushing component is movably connected to the sliding sleeve.
