PROBLEM TO BE SOLVED: To provide a method for forming an opening of a blow molding that allows efficient mounting of an insert member and removal of a cut-off piece from the opening.SOLUTION: In a method for forming an opening of a blow molding having an insert member embedded in the opening, an insert mounting device 70 is arranged so as to be close to a blow molding die 60, and the insert mounting device 70 is formed with insert holding parts 71 and cut-off piece locking parts 72. The blow molding die 60 holds a cut-off piece 14 cut off from the opening on a cut-off piece holding part 62. After the insert member 30 is mounted to the blow molding die 60 with the insert member 30 being held by the insert holding parts 71, the insert mounting device 70 is slid and the cut-off piece 14 is sandwiched by the cut-off piece locking parts 72 to remove the cut-off piece 14 from the cut-off piece holding part 62, and mounting of the insert member 30 and removal of the cut-off piece 14 are performed in one step.SELECTED DRAWING: Figure 9
【課題】効率的にインサート部材を取付けるとともに開口部から切除された切除片を取除くことができるブロー成形品の開口部の形成方法を提供する。【解決手段】開口部にインサート部材が埋設されるブロー成形品の開口部の形成方法において、インサート取付装置70をブロー成形金型60に近接可能に配置し、インサート取付装置70にインサート保持部71と切除片係止部72を形成する。ブロー成形金型60は、開口部から切除された切除片14をブロー成形金型の切除片保持部62に保持する。インサート保持部71にインサート部材30を保持して、ブロー成形金型60にインサート部材30を取付けた後、インサート取付装置70をスライドさせて切除片係止部72で切除片14を挟持して、切除片保持部62から切除片14を取除くとともに、インサート部材30の取付けと切除片14の取除きを1工程で行う。【選択図】図9
