PURPOSE: A blowing device for a PET bottle forming machine and an initial setting method using the same are provided to enable a simple and convenient initializing work even if a mold is changed into a new mold. CONSTITUTION: A blowing device (400) for a PET bottle forming machine comprises a high-pressure nozzle unit (410) and an extension rod lift unit (420). The high-pressure nozzle unit is installed on the top of a body mold device to be lifted, and an extension rod (B) is inserted into the high-pressure nozzle unit. The high-pressure nozzle unit is composed of a cylinder (411), a piston (412), a connector, and an insertion hole (414) and transfers high-pressure supplied from the outside to the inner side of a pre-form. The extension rod lift unit is installed on the top of the body mold device to be adjacent to the high-pressure nozzle unit and lifts up and down the extension rod installed in the high-pressure nozzle unit. |
