PURPOSE: To obtain a method and a device for insert blow molding, capable of reducing an insert travel time of an insert member and enhancing an insert positional accuracy. CONSTITUTION: An inserting device 120 for inserting a plurality of insert members 20 to a plurality of preforms 50 subjected to a temperature regulating stage is disposed opposedly to a temperature regulating part 72 for conducting a temperature regulating stage previous to a blow molding stage. The inserting device 120 is provided with a plurality of sets of pair chucking pieces 122 for supporting the plurality of insert members 20 along a direction parallel to the arranging direction (a direction B) of the plurality of preforms 50. A forward and backward drive part 126 for moving the plurality of sets of pair chucking pieces 122 forward and backward is provided. The insert members 20 are horizontally driven forward and backward in a direction (a direction C) orthogonal to the arranging direction of the preforms 50. The plurality of insert members are driven forward and backward by the plurality of sets of pair chucking pieces 122 between a position retracted from a transport path D for the preforms 50 and a position on the transport path D for the preforms 50. |
