LOCK MEMBER MANUFACTURING METHOD, AND VEHICLE LID LOCK DEVICE PROVIDED WITH LOCK MEMBER
To provide a lock member manufacturing method capable of reducing a void fraction by a simple method, and to provide a vehicle lid lock device provided with the lock member.SOLUTION: A manufacturing process of a rod part 52 comprises: a first step of arranging a slide pin 83 at a holding part 821 by inserting the slide pin 83 in a first die 81 and a second die 82; a second step of injecting and filling a molten resin A in molding spaces 810 and 820 in the respective first and second dies 81 and 82 in a state where the slide pin 83 is held by the holding part 821; and a third step of pulling out the slide pin after solidifying the molten resin A via cooling. In the third step, a space formed by pulling out the slide pin 83 is formed as a hollow part 801a of a molded article 800.SELECTED DRAWING: Figure 1
【課題】簡素な方法でボイド率の低減を図ることができるロック部材の製造方法及びロック部材を備えた車両用リッドロック装置を提供する。【解決手段】ロッド部５２の製造工程は、スライドピン８３を第１及び第２の金型８１，８２に挿入してスライドピン８３を保持部８２１に配置する第１工程と、スライドピン８３が保持部８２１に保持された状態で第１及び第２の金型８１，８２の成形用空間８１０，８２０に溶融樹脂Ａを射出して充填する第２工程と、溶融樹脂Ａを冷却して固化した後に前記スライドピンを引き抜く第３工程と、を有し、第３工程においてスライドピン８３が引き抜かれることにより形成された空間が成形品８００の中空部８０１ａとして形成される。【選択図】図１
