【考案の詳細な説明】
本考案は吹込成形製蓄電池用電槽（以下電槽という）に
関する。[Detailed Description of the Invention] The present invention relates to a blow-molded storage battery case (hereinafter referred to as a case).
従来より第６図に示すように電槽底部１４の外面には横
方向に凹溝１５を設け、内面には該凹溝１５に対応して
鞍１６を形成した電槽が提案されている。Conventionally, as shown in FIG. 6, a battery case has been proposed in which a groove 15 is provided in the lateral direction on the outer surface of the bottom 14 of the battery case, and a saddle 16 is formed on the inner surface in correspondence with the groove 15.
この電槽は鞍が一体に形成され機械的強度に優れてはい
るが、吹込成形で製造するので凹溝１５の型割れ線に対
応する鞍１６の中心１６ａが金型で食切られて陥没し極
板群を安定して保持することができなかった。This battery case has a saddle integrally formed and has excellent mechanical strength, but since it is manufactured by blow molding, the center 16a of the saddle 16 corresponding to the mold break line of the groove 15 is cut away by the mold and caved in. However, it was not possible to stably hold the electrode plate group.
本考案は上記の欠点に鑑みて創案したものである。The present invention was devised in view of the above drawbacks.
以下本考案の一実施例を図面に基づき詳述する。An embodiment of the present invention will be described below in detail based on the drawings.
１はポリエチレン等の熱可塑性プラスチックからなる吹
込成形製電槽であり１，２は吹込成形時の型割れ線であ
る。1 is a blow molded battery case made of thermoplastic such as polyethylene, and 1 and 2 are mold breaking lines during blow molding.
３は電槽胴部、４は電槽底部である。3 is the body of the battery case, and 4 is the bottom of the battery case.
底部４の外面には横方向に並夕１ルた凹溝５を設け、内
面には該凹溝５と対応した鞍６を形成する。The outer surface of the bottom part 4 is provided with grooves 5 arranged in a row in the lateral direction, and the inner surface is formed with a saddle 6 corresponding to the grooves 5.
そして鞍６には極板群７が載置される。！た吹込成形時
の肉回りを良好にするため底部４の四隅には切欠部８が
形成される。A group of electrode plates 7 is placed on the saddle 6. ! Notches 8 are formed at the four corners of the bottom 4 to improve the circumference during blow molding.
９は凹溝５の両端に下方に向かって突出した突条であり
、対応する鞍６の隅部は略直角に形成される。Reference numeral 9 denotes protrusions projecting downward at both ends of the groove 5, and the corresponding corners of the saddle 6 are formed at approximately right angles.
１０は凹溝５の型割れ線２を中心として山形状に凹んだ
凹部であり、対応する鞍６の中心は平面状に形成される
。Reference numeral 10 denotes a concave portion concave in a mountain shape centered on the mold-breaking line 2 of the concave groove 5, and the center of the corresponding saddle 6 is formed in a flat shape.
例えば、吹込成形においては、成形金型が締る際に、円
筒状等の状態で供給された樹脂の一部を型外に押し出す
ため、成形品の型割れ線部に第６図の１６ａに示すよう
に薄肉部を生じせしめる。For example, in blow molding, when the mold is tightened, a part of the resin supplied in a cylindrical shape or the like is pushed out of the mold. A thin section is created as shown.
しかるに成形金型の型締め部を内側に凸部を設けた形状
にして成形品の型割れ線部に型割れ線部を中心として凹
部が形成されるようにしておくと、成形品の型割れ線部
内側は平面状となる。However, if the mold clamping part of the molding die is shaped with a convex part on the inside so that a concave part is formed around the mold breaking line of the molded product, mold cracking of the molded product will occur. The inside of the line portion is flat.
したがって、凹溝５の型割れ線部２を中心として凹部を
設けるようにすると、対応する鞍６の中心は平面状とな
る。Therefore, if a concave portion is provided around the mold break line portion 2 of the concave groove 5, the center of the corresponding saddle 6 will be planar.
本考案は上記の如く、電槽底部４に設けた凹溝５の型割
れ線２を中心として凹部１０を形成したので、鞍６の中
心６ａは平面となり、極板群を安定的に保持することが
できる。As described above, in the present invention, the recess 10 is formed around the mold break line 2 of the recessed groove 5 provided in the bottom 4 of the battery case, so the center 6a of the saddle 6 becomes a flat surface, which stably holds the electrode plate group. be able to.
尚、第４図の如く凹溝５を両端に向かって上方に傾斜し
て形成すれば一層鞍６を平面にすることができる。Incidentally, if the grooves 5 are formed to be inclined upward toward both ends as shown in FIG. 4, the saddle 6 can be made even more flat.
第１図は本考案に係る電槽の斜視図、第２図は電槽の底
面図、第３図は第２図のＡ−Ａ断面図、第４図、第５図
は第２図のＢ−Ｂ断面図、Ｃ−Ｃ断面図であり、極板群

図と同様の断面図である。
１：電槽、４：底部、５：凹溝、１０：凹部。Figure 1 is a perspective view of the battery case according to the present invention, Figure 2 is a bottom view of the battery case, Figure 3 is a sectional view taken along line A-A in Figure 2, and Figures 4 and 5 are the same as in Figure 2. They are a BB cross-sectional view and a CC cross-sectional view, showing the state in which the electrode plate group is mounted, and Figure 6 is the fourth diagram showing a conventional battery case.
It is a sectional view similar to the figure. 1: Battery case, 4: Bottom, 5: Concave groove, 10: Concave part.
