The present utility model discloses a rapid cooling device for an injection blow molding machine, comprising an injection blow molding machine mold, a circulating hose and a water cooling head. A heat conduction cavity is formed at the bottom inside the injection blow molding machine mold, a heat conduction copper pipe penetrates through the heat conduction cavity, and a fan is installed on one side of the radiator. The present utility model is provided with a disassembly and assembly structure: the heat conduction copper pipe can be pulled out from the heat conduction cavity by rotating and removing the positioning nut and the fastening nut; during installation, the heat conduction copper pipe is inserted into the heat conduction cavity, the positioning nuts on both sides are tightened to prevent the heat conduction copper pipe from moving, then one end of the circulating hose is inserted into the gap between the second external thread and the inner pipe, and then the fastening nut is tightened toward the split groove, so that the second external thread divided by the split groove fastens and clamps the circulating hose inserted into the second external thread, thereby making the disassembly and assembly of the heat conduction copper pipe more convenient and realizing convenient disassembly and assembly between the device and the injection blow molding machine mold.
