負極端子板７を押圧するように、その立上シ部８の先端
部分９を内方に折り曲げて密閉した構造となっている。In FIG. 1, inside a metal can 1 which also serves as a positive electrode terminal, there is a positive electrode mainly made of a positive electrode active material such as silver oxide, mercury oxide, manganese dioxide, etc., and a separator 3 disposed on top of the positive electrode.
and an electrolyte-impregnated material 4, which are impregnated with an alkaline electrolyte. The opening of the metal positive electrode can 1 is configured to press a negative electrode terminal plate 7 filled with a negative electrode mixture 6 made of a mixture of zinc powder and an alkaline electrolyte through a synthetic resin gasket 6 having a cross-sectional shape. In addition, the tip portion 9 of the rising portion 8 is bent inward to form a sealed structure.
従来、この電池に用いられていた封口金型の内面は、表
面粗さが０．１Ｓ以下の鏡面状態になっており、正極先
端部を内方へ折シ曲げて封口した時、封口金型と電池と
の型離れが悪いという問題があった。Conventionally, the inner surface of the sealing mold used for this battery has a mirror surface with a surface roughness of 0.1S or less, and when the positive electrode tip is bent inward and sealed, the sealing mold There was a problem that the mold did not separate easily from the battery.
また、金属正極缶１の外周面１ａが鏡面状態であれば、

電池外面に微細な傷が入って高温多湿で保管されると、
錆が発生するという問題もあった。Moreover, if the outer peripheral surface 1a of the metal positive electrode can 1 is in a mirror-like state,
Since the surface is coated with nickel plating, etc., when sealing with a mold, nickel will not fall off or adhere to the sealing mold, and
If there are minute scratches on the outside of the battery and it is stored in high temperature and humidity,
There was also the problem of rust.
発明の目的
本発明は前述の欠点を解消し、封口金型１０ａを表面粗

作業の安定と、缶外面の傷防止を図９、耐防錆効果の向
上を図ることを目的とする。Purpose of the Invention The present invention solves the above-mentioned drawbacks and makes the sealing mold 10a matte-like with a surface roughness of 18-0.5S, thereby stabilizing battery sealing work and preventing scratches on the outer surface of the can. 9. The purpose is to improve the anti-corrosion effect.
発明の構成
本発明は、上記の目的□を達成するために、封口金型１
０ａの内面１０Ｃの表面粗さをｌ５−０．５Ｓの梨地状
にし、対日時の封口金型１０ａと電池の正極缶１との型
離れを良好にすることを特徴とする。Structure of the Invention In order to achieve the above object □, the present invention provides a sealing mold 1.
The surface roughness of the inner surface 10C of 0a is made into a satin finish of 15-0.5S, and the mold separation between the sealing mold 10a and the positive electrode can 1 of the battery is improved.
このような封口金型を用いて封口を行うと、対日時の型
離れを良好に保つことができるとともに、缶表面に施し
だニッケルメッキなどの剥離、脱落を防ぐことができる
。When sealing is performed using such a sealing mold, it is possible to maintain good separation from the mold when compared to Japan, and it is also possible to prevent the nickel plating applied to the can surface from peeling off or falling off.
実施例の説明 以下、本発明の実施例を第２図によシ説明する。Description of examples Hereinafter, an embodiment of the present invention will be explained with reference to FIG.
正極缶１と負極端子板７をカップリングした後、封口金
型１０ａ内へその下方よシ、プランジャー１０ｂによシ
一定の圧力を加えて挿入していく。After the positive electrode can 1 and the negative electrode terminal plate 7 are coupled, they are inserted downward into the sealing mold 10a while applying a constant pressure to the plunger 10b.
その対日時に封口金型１０ａと電池の缶１の外周面１ａ
とが強くこすれ合い、型離れの不良や電池外面の傷が起
きたりする。At that time, the sealing mold 10a and the outer peripheral surface 1a of the battery can 1
The two may rub against each other, resulting in poor release from the mold or scratches on the outside of the battery.
そこで、従来使用していた金型と本発明の金型において
、型離れの不良及び電池外面の傷等のテストを行った。Therefore, tests were conducted on the conventionally used mold and the mold of the present invention to check for defects in mold release and scratches on the outer surface of the battery.
テスト方法及び結果
従来の金型と本発明の金型で各１０００個の電池を試作
し、この１０００個の電池を封口する間に型離れが悪か
った回数と、電池外周面の傷の有無を調査した。Test method and results 1,000 batteries were prototyped each using the conventional mold and the mold of the present invention, and while the 1,000 batteries were sealed, the number of times the mold separated poorly and the presence or absence of scratches on the outer surface of the battery were determined. investigated.
テスト結果は次表の通シであった。The test results were as shown in the table below.
上記の結果よシ、封口金型１０ａの内面１００を０．５
Ｓ〜１Ｓの粗さの梨地状にしだものは、従来の金型よ
りも型離れも良く、それにともなう正極缶外周面の傷も
なくなった。また粗さ１８以上のものでは型離れ不良の
ものはなかっだが、粗いために缶外周面の傷が多発して
いた。According to the above results, the inner surface 100 of the sealing mold 10a is 0.5
The satin-like weeping with a roughness of S to 1S was easier to release from the mold than the conventional mold, and there were no accompanying scratches on the outer circumferential surface of the positive electrode can. In addition, when the roughness was 18 or more, there were no mold release defects, but due to the roughness, there were many scratches on the outer peripheral surface of the can.
