工程とのつながりを連続にできない欠点がある。Lattice bodies for lead-acid batteries are generally manufactured by gravity casting or machining. The gravity casting method is a method in which the molten metal is poured into a pair of matching molds, which are called book molds and in which the shape of a lattice is engraved, and the lattices each having a shape as shown in FIG. 8A are manufactured one by one.
This method has a drawback that the production efficiency of the lattice is poor because the production of the lattice is a batch process, and the connection with the paste filling process, which is a subsequent process, cannot be made continuous.

生産性は著しく向上したが、その反面次のような欠点が
あった。Therefore, in recent years, a machining method has been adopted as a method of manufacturing a lattice body replacing the conventional gravity casting method. A typical example of this machining method is a method of manufacturing a lattice by an expanding method. The grid manufactured by this method has a shape as shown in FIG. 8 (B), and the productivity of the electrode plate is remarkably improved because the connection with the subsequent steps can be continuously performed. There was a flaw.

電池の充放電による格子の著しい伸びで、正極板が負極
ストラップに接触して短絡を起こし、電池の寿命が短い
という欠点があった。また、格子体の電気抵抗が大き
く、電池の電圧特性が悪いという欠点もある。First, in order to manufacture an expanded lattice, a lead alloy ingot must be formed into a sheet by a method such as rolling. Next, this lead alloy sheet is processed into an expanded lattice by a developing machine, which requires a very large-scale device for the production and development of the lead alloy sheet, and the grids that can be produced by this method are mainly lead. -Limited to calcium alloys, it is difficult to apply to lead-antimony alloys that are often used in lead-acid batteries. A further fatal drawback is that the lattice body is very stretchable, as can be easily inferred from the lattice shape of FIG. 8 (B). In particular, when the expanded grid is used for the positive electrode plate, there is a drawback that the positive electrode plate comes into contact with the negative electrode strap to cause a short circuit due to the significant expansion of the grid due to charging and discharging of the battery, resulting in a short battery life. In addition, the grid has a large electric resistance and the voltage characteristics of the battery are poor.
【０００５】そこでこれらの欠点を解決するために提案
されたのが鋳造法による連続的な格子体の製造方法であ
る。これまでにも種々の考案がなされているが、例えば
米国特許第４，３４９，０６７号によれば、格子体の形

載されている。従来の提案はいずれも基本的には上述し
た方式によっているが、なお、いくつかの欠点を有して
いる。Therefore, a method for producing a continuous lattice by a casting method has been proposed to solve these drawbacks. Although various inventions have been made so far, for example, according to US Pat. No. 4,349,067, a molten metal supply portion called a shoe is brought into contact with a rotary drum having a lattice shape engraved, and the drum is connected to the drum. An apparatus is described in which the grooves of a mold formed between the shoe and the shoe are filled with a molten metal to continuously cast a lattice. All of the conventional proposals are basically based on the above-mentioned method, but still have some drawbacks.
【０００６】すなわち、この方式で鋳造される格子体

から予想されるように、図６に示す断面形状を有する従
来の合わせ鋳型を用いた重力鋳造法による格子体に比べ
て、充填したペーストが脱落しやすいという欠点があっ
た。That is, since the lattice body cast by this method is only engraved on the outer periphery of the drum, it has a cross-sectional shape as shown in FIG. 7, and as expected from this shape, There is a drawback that the filled paste is more likely to fall off as compared with the lattice body formed by the gravity casting method using the conventional matching mold having the cross-sectional shape shown in FIG.
【０００７】また、溶湯の供給部であるシューは固定さ

転することになり、製造された格子体のシュー面側には
多数の鋳巣が生じ、とくに正極板に使用した場合には格
子の腐食が著しいため、やはり寿命性能のよい電池が得
られないという欠点があった。Further, since the shoe, which is the molten metal supply section, is fixed, the drum rotates while sliding with respect to the shoe, and a large number of cavities are formed on the shoe surface side of the manufactured lattice. In particular, when it is used for the positive electrode plate, the grid is remarkably corroded, so that a battery having a good life performance cannot be obtained.

う欠点もあった。Further, since it is difficult to cool the molten metal supplied to the mold in the above continuous casting method, Pb-Ca alloy or Pb-low Sb
There is also a drawback that only a grid body of a lead alloy having a relatively narrow solidification range such as an alloy can be manufactured, and a grid body having a large thickness cannot be manufactured.

Even if the manufacturing efficiency was good, the characteristics of the lattice were poor.

Reference numeral 0 is an apparatus for heating the mold. The supply of the molten metal is provided at a place where it enters the straight part 7 of the mold in FIG. However, if the position is not appropriate, there is a risk that the molten metal will flow in and leak before the pair of strip-shaped molds are combined to form a mold, so that the position of the molten metal supply port needs to be careful.

By tilting the annular mold in this way, the sprue can be set to the rear part to some extent, and the device itself can be made compact.

First, the air cylinder 17 is operated to press the annular molds in the linear portions 7 of the annular molds A and B to form a combined mold, and then a driving device (not shown) connected to the sprocket 5 is operated to operate the sprocket. The chain moves by meshing with the teeth, and the strip-shaped mold connected to the chain moves in the direction of the arrow in FIG.

When the mold temperature reaches about 150 ° C., a mold release agent is applied to the mold surface. At this time, the temperature of the mold decreases, so the temperature rises again and the mold is heated to 160 to 170 ° C.
When the temperature reaches, the molten metal whose temperature has been previously raised to 450 to 480 ° C. is poured into the V-shaped groove of the casting mold through the supply nozzle.

型全体に溶湯が行わたる。The molten metal fills the engraved grooves in the lattice shape of each of the matching molds. The molten metal flow at this time will be described with reference to FIG. After the engraved portion 21 is filled, the molten metal is applied to the entire mold by sequentially passing through the portion 24 corresponding to the vertical crosspiece and extending into the horizontal groove 23.

て格子骨が切れることはない。A connecting groove 25 is formed between the adjacent mating molds.
Connected only by. Since the connecting groove 25 is located in the middle of the portion 23 corresponding to the horizontal crossbar, the molten metal does not directly flow to the horizontal crossbar, so that when the molten metal flows out to the adjacent mold, the connecting groove 25 is It becomes resistance and the boiling water does not work enough to cut the lattice bone.

状を図３のようにしたのは上述した理由からである。If the connecting groove 25 with the adjacent mold is located at the same position as the lateral lattice bone 23 and is provided so as to communicate with the adjacent lattice body, the annular mold is inclined as shown in FIG. The molten metal that has flowed into one mold does not stay in the mold but directly flows out to the horizontal crossbars, and flows down in the lower direction. Therefore, the boiling water does not work and the lattice bones are cut off, and it becomes impossible to manufacture a good continuous lattice. In the present invention, the shape of the lattice body provided on the strip-shaped mold is as shown in FIG. 3 for the above-mentioned reason.

The continuous grid thus cast is processed into a shape as shown in FIG. 5, filled with a lead storage battery paste, and cut into individual plates to form electrode plates.

５゜以上が好ましいことがわかった。As described above, in the present invention, the annular mold is tilted so that the traveling direction is lowered. This is to prevent the molten metal injected into the mold from flowing backward and leaking from the gap between the molds. As a result of experiments, it was found that the inclination angle θ is preferably about 5 ° or more.

As one side of the grid is not flat, the paste filling is good, and not only is an electrode plate with excellent vibration resistance obtained, but since there are no sliding parts, no porosity is formed and corrosion resistance is good. Lattice bodies were obtained continuously.
