本発明は鉛あるいは鉛合金からなる鉛蓄電池用基体の鋳
造方法の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a method for casting a base body for a lead-acid battery made of lead or a lead alloy.

ルク層のもつ保温効果は非常に大きい故、格子体の様に
肉厚が小さく複雑な形状の金型の丁みずみまで十分に溶
湯を流し込むためには、コルク層の形成は欠か丁ことが
小米ないものである。Conventional technology b Conventionally, grid bodies for lead-acid batteries are made of Pto-based alloy or Pb-
In this case, the mold is made of gold, and the lattice body is produced by casting 0a series alloy.
It is manufactured continuously at an extremely high speed of about 16 sheets. This mold is heated to about 160 to 230°C by a heater, and the surface of the mold that comes into contact with the molten lead alloy is designed to facilitate release of the cast lattice and to enhance the heat retention effect of the mold. A layer of cork powder called a lubricant is formed on the surface. This cork layer is formed at the beginning of the casting operation by mixing cork with water together with a suitable binder and spraying it onto the heated mold surface. Because the cork layer has a very large heat-insulating effect, it is essential to form a cork layer in order to pour the molten metal into every inch of the mold, which has a small wall thickness and complex shape, such as a lattice. There is no small rice.
更にコルク層の重要な役目に鋳造された格子体の重量馨
規制するということがある。即ち、°コルク層を厚くす
ると鋳造される格子体は軽くなり、逆にコルク層を薄く
下ると格子体は重くなることである。実際には、格子体

験とスプレーによる吹きつけに対する高度の熟練が要求
されるわけであり、コルク層の所謂小米、不出来によっ
て格子体の生産高が左右されてしまうわけである。Furthermore, the important role of the cork layer is to control the weight of the cast grid. That is, the thicker the cork layer, the lighter the cast lattice will be, and conversely, the thinner the cork layer, the heavier the lattice. In practice, the grid must have a specified weight and be cast within a certain weight range. Therefore, the formation of the cork layer requires experience in casting and a high level of skill in spraying, and the production yield of the lattice body is affected by the so-called failure of the cork layer. be.
発明が解決しようとする問題点
上記コルク層は鋳造時間の経過共に脱落して行き、ある
程度以上脱落すると格子体は鋳造されても重量が規定範
囲以上になってしまう。更に脱落が進むお鋳造不可能な
状態となる。これは保温効果の減少により、複雑な形状
の金型の丁みずみまで溶湯が流れなくなるからである。Problems to be Solved by the Invention The above-mentioned cork layer falls off as the casting time progresses, and if it falls off to a certain extent, the weight of the lattice body will exceed the specified range even if it is cast. As the pieces fall off further, it becomes impossible to cast them. This is because the molten metal cannot flow to every corner of the complex-shaped mold due to the reduction in heat retention effect.
実際には鋳造された格子体の重量が規定範囲の上限に達
した時再度コルクの吹付けを行なわなくてはならないと
いうこおである。従来コルク吹付は作業は、１日に２回
行なってセリ、この吹付作業は前述のように高度の熟練
を要するものであり、作業者がその為にこうむる神経的
疲労は相当である。さらに何十台という鋳造機がほとん
ど同時にこのコルク吹付は作業を行うためコルクの噴霧
による作業環境の悪化をも招いている。In practice, when the weight of the cast grid reaches the upper limit of the specified range, it must be sprayed with cork again. Conventionally, cork spraying is carried out twice a day, and as mentioned above, this spraying operation requires a high degree of skill, and the operator suffers from considerable nervous fatigue. Furthermore, since dozens of casting machines perform cork spraying almost simultaneously, the cork spray causes a deterioration of the working environment.
このようにコルクの吹付は作業は種々の問題点を有して

のである。しかし実際にはセラばツク層橿就の保温効果

ベルでは便用出来でも量産設備としてはＶ用小米ない。As described above, cork spraying has various problems, and various improvements have been made. For example, when a ceramic layer is molded onto the inner surface of a mold, or when cork is mixed with water, a water-soluble phenolic resin is mixed in, and the phenolic resin hardens under heat, creating an adhesive force between the cork and the mold. It is like being able to extend the time it takes for the cork to fall off. However, in reality, the thermal insulation effect of the ceramic layer cannot compete with that of cork, so although it can be used as a toilet at the laboratory level, it is not suitable for mass production equipment.
また水溶性フェノール樹脂を混合する方法も、数十台の
鋳造機がある中で、−斉にコルクの吹付けを行なった場
せ、ホルマリン臭がひどくなり、作業環境の悪化はコル
ク単独の場会の比ではなくなる。In addition, the method of mixing water-soluble phenolic resin is difficult to solve when there are dozens of casting machines, and if cork is sprayed all at once, the odor of formalin becomes severe and the working environment worsens. It will no longer be compared to the society.
従ってこの方法も現果には使用小米ない。Therefore, this method also does not use small rice for actual fruit.
しかしコルクが鋳造時間の経過と共に脱落して行くこと

、 少の凹凸部を無数に形成したものである。However, it is inevitable that cork will fall off as the casting time progresses, and if we cannot find a material that can replace cork, the problem is that the time required for cork to fall off can be extended. Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks by forming a sprayed metal layer on the inner surface of the mold for casting a substrate, and using the sprayed layer, the metal for casting the substrate is removed. This mold has countless small irregularities formed on the inner surface of the mold.

。Effect When cork is sprayed onto the inner surface of the mold on which a metal sprayed layer with countless minute irregularities has been formed, the cork will penetrate into these minute irregularities. This allows the cork powder to be retained within the sprayed layer, greatly extending the time it takes for it to fall off.

造用金型２の内表面上に金属溶射層を形成する。Example A mold 2 for casting a base body made of cast iron, which has a base groove on the inner surface of the mold that has the same shape as the base body 1 and has a depth slightly larger than 10 of the wall thickness of the base body 1, is used as in the conventional one. prepare. The base casting mold 2 usually consists of a pair of split molds, one fixed and one movable, of which only one is shown in FIG. First, a metal spray layer is formed on the inner surface of the base casting mold 2.

最適であった。Metal spraying involves melting mixed IX gold powder consisting of 5.5% At, 5% MO, and the rest N1 in a mixed gas flame of O, -0, and H, and depositing minute droplets on the inner surface of the base casting mold 2. Conflict with others to form jealousy. At this time, the only part that needs to be formed with a metal spray layer is the part marked with an extended point in Figure 2, and the other parts do not require a metal spray layer. Therefore, unnecessary parts may be masked. Therefore, spraying should be carried out so that a uniform metal spray layer is formed on the areas where the blind spots in Figure 2 have been applied, and the other areas should be sprayed. If the porosity of the metal sprayed layer is 10 to 30%, it can be changed arbitrarily, but if the porosity is increased to 30%, the metal sprayed layer cannot be used for casting the substrate. Since the mold 2 is frequently opened and closed, the metal sprayed layer may chip and sag, and in fact, a porosity of about 20% was optimal.
また金属溶射層の厚みとしては、０．２〜０．５ｍ＋と
じた。The thickness of the metal sprayed layer was 0.2 to 0.5 m+.
上記実施例によれば、従来２０００〜３０００枚鋳造す

０００枚程度まで１回のコルク吹き付けで可能となった
。これは１台の鋳造機の１日の生産数量に当る。即ち、
１日に１回のコルク吹き付は作業で済むようになった。According to the above example, when 2,000 to 3,000 sheets were cast, the weight of the lattice body reached the upper limit of the specified range due to the cork layer falling off, and the cork layer was reshaped.
It is now possible to print up to 1,000 sheets with one cork spray. This corresponds to the daily production quantity of one casting machine. That is,
Spraying the cork once a day is now a simple task.

溶射層が剥離することが起り問題があった。In addition to the above-mentioned example, another method can also be considered in which after forming the metal spray N on the inner surface of the mold, carve a groove in the base body that has the same shape as the base body 1 and has a depth slightly larger than the thickness of the base body 1. but,
Since actual molds incorporate various methods for venting air, there is a problem in that the sprayed metal layer may peel off during processing.

保持出来るような能力をもった多孔質ではなか−った。In addition, I tried applying a plasting process to the inner surface of the base casting mold 2 and forming a cork layer on the inner surface of the base casting mold 2 by simply attaching five concave grooves of single metal, but the unevenness formed by the plasting process At a certain level, we tried forming a cork layer and then forming a cork layer on top of it, but the porosity of the cork layer was less than 1%, and the ability to retain cork particles was poor. It was not porous.
即ち、セラばツク層（亀密丁ぎるわけである。In other words, it is a ceramic layer.

。Effects of the Invention As mentioned above, according to the present invention, the time for the cork layer to fall off due to the passage of casting time can be carefully extended, and the productivity of the substrate can be improved, which has great industrial value. .
