The present application discloses a die head lifting device for an automatic hollow blow molding machine. The die head lifting device for the automatic hollow blow molding machine is fixed between a die head and a frame, and comprises a hydraulic motor, a driving rod, a driven rod and four worm gears. A transmission sprocket is arranged at the shaft end of the hydraulic motor, a double sprocket is sleeved on the driving rod and arranged corresponding to the transmission sprocket, a driven sprocket is sleeved on the driven rod and arranged corresponding to the double sprocket, and a chain is arranged between the double sprocket and the driven sprocket. Turbines are respectively arranged at two ends of the driving rod and the driven rod, and the four worm gears are respectively arranged corresponding to the turbines. The die head lifting device for the automatic hollow blow molding machine has a simple structure and convenient maintenance, and can conveniently adjust the height between the parison and the mold. The height adjustment between the parison and the mold is realized through the transmission of the turbines and the worm gears, with high precision and strong reliability.
