The present utility model discloses an extrusion mechanism for a barrel-storage hollow molding blow molding machine, comprising a barrel, a screw arranged in the barrel, and a reduction gearbox connected with the screw. The front end of the barrel is connected with a continuous discharge die head. The length of the threaded section of the screw is shorter than that of the barrel, and the screw can move in the barrel along the length direction. The end of the screw is connected with an oil cylinder capable of pushing the screw to move. The barrel is divided into multiple sections and controlled by a segmented temperature controller. The present utility model overcomes the defects of traditional continuous extrusion and die head storage by adopting barrel storage, is not only suitable for the production of large plastic products, but also has accurate temperature control, does not require disassembly and cleaning of the die head, and reduces the possibility of damage to the die head caused by repeated disassembly and cleaning.
