POWER STORAGE MODULE MANUFACTURING APPARATUS AND METHOD

To provide power storage module manufacturing apparatus and method that can reduce stress to be applied to a resin portion when a communication hole forming portion is removed from a communication hole.SOLUTION: A power storage module 4 includes an electrode laminate 11 containing a plurality of electrodes E laminated in a lamination direction D1, and a seal member 12 surrounding the electrode laminate 11. The plurality of electrodes E include a bipolar electrode 14. The seal member 12 includes a first resin portion 23 provided with a communication hole 23a communicating with an internal space V provided between adjacent electrodes E. The manufacturing apparatus 100 for the power storage module 4 includes a mold main body M for forming a first resin portion 23 by injection molding, an insert die 42 which is attached to the mold main body M and has a communication hole forming portion 44 for forming a communication hole 23a, a pressing member 60 that is movable with respect to the insert die 42 so as to press the first resin portion 23, and a moving mechanism 70 which is fixed to the insert die 42 and moves the pressing member 60 relatively to the insert die 42.SELECTED DRAWING: Figure 16 【課題】連通孔形成部が連通孔から除去される時に樹脂部にかかる応力を低減できる蓄電モジュールの製造装置及び製造方法を提供する。【解決手段】蓄電モジュール４は、積層方向Ｄ１に積層された複数の電極Ｅを含む電極積層体１１と、電極積層体１１を取り囲むシール部材１２とを備える。複数の電極Ｅは、バイポーラ電極１４を含む。シール部材１２は、隣り合う電極Ｅ間に設けられた内部空間Ｖと連通された連通孔２３ａが設けられた第１樹脂部２３を備える。蓄電モジュール４の製造装置１００は、第１樹脂部２３を射出成形により形成するための金型本体Ｍと、金型本体Ｍに取り付けられ、連通孔２３ａを形成するための連通孔形成部４４を有する入れ子型４２と、第１樹脂部２３を押圧するように入れ子型４２に対して移動可能な押圧部材６０と、入れ子型４２に固定され、押圧部材６０を入れ子型４２に対して相対移動させる移動機構７０とを備える。【選択図】図１６
