ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a welding mold for electrode plate lugs and straps of positive and negative electrode groups of lead-acid batteries, and strap parts of positive and negative electrode groups of lead-acid batteries.

７２以下であっても鋳型を陽、陰極群個別に用意出来て
、金型の温度条件を変更することで溶着させることが可
能であった。Conventional technology In the so-called cast-on method of welding the positive and negative electrode groups of conventional automotive lead-acid batteries, the thickness of the cathode plate is 1 mm compared to the thickness of the anode plate.
Even if it was 72 or less, molds could be prepared separately for the anode and cathode groups, and welding could be performed by changing the temperature conditions of the mold.

る方法ぐらいしかなかった。However, in batteries such as small sealed lead-acid batteries where the space between the plates of the anode group and the cathode group is narrow, the anode and cathode groups must be cast in the same mold. In particular, for small sealed lead-acid batteries, the anode plate thickness is thicker than the cathode plate thickness, and casting must be performed in the same mold at the same mold temperature.To determine the difference in conditions between the anode group and the cathode group, The only option was to change the temperature conditions of the hot water.

群の不良が多く発生する欠点を有している。Problems to be Solved by the Invention However, in the conventional cast-on method described above, even if the thickness of the cathode plate is extremely thin compared to the thickness of the anode plate, the same mold is used for casting. Since it is not possible to create a temperature difference between the molds, the mold temperature is increased to melt the anode plate edges. Therefore, since the cathode plate has a thin edge, the root of the edge of the cathode plate may become discolored or discolored, resulting in insufficient welding strength and breakage of the edge, resulting in many defective electrode groups. have.

も２ｋｇ／ｍｍ”以下となって極端に悪くなる。A small sealed lead-acid battery using a cast-on method in which casting is performed using a positive and negative electrode group mold 3 that simultaneously forms an anode strap 1 and a cathode strap 2 shown in FIG. 1 will be described.
The lugs 5 of the anode plate 4 and the lugs 5 of the cathode plate 6 shown in FIGS. 2 and 3
Assuming that the width of the lugs of ' are the same (w=w'), the thickness t of the lugs 5 of the anode plate 4 is 3.4 mm, and the thickness t2 of the lugs 5' of the cathode plate 6 is 2.1 mm &. The ratio is 1:0.6
Naturally, the ratio of the cross-sectional area of the anode lug pHl0Iz and the cross-sectional area of the cathode lug Nmm'' is 1:0.6, and the thickness 11 of the lug 5 of the cathode plate 6 is also 2.1 mm, so even if casting Problems such as fading, discoloration, or breakage of the cathode plate 6 do not occur, and welding strength of 3 kg/n+m'' can be ensured. On the other hand, if the edge length t of the anode plate 4 is 3.4 mm and the thickness of the edge 5' of the cathode plate 6 is 1.2 mm, the edge ratio is t:o, 3s, and the thickness of the cathode plate 6 is also Since the thickness of the electrode group mold 3 is 1.2 mm, the temperature of the electrode group mold 3 must be set high (otherwise, the fusion between the ears 5 of the anode plate 4 and the anode strap will be poor, and the amount of lead in the cathode strap 2 will increase the amount of heat during casting). However, the cathode plate 6 becomes discolored, discolored, or broken, and the welding strength becomes extremely poor, becoming less than 2 kg/mm''.

The reliability of welding can be ensured by specifying the ratio in design such that the ratio is 1:0.5 or more. Note that the molten lead 11 at 10 is a pole column. Figure 4 shows a conventional lead-acid battery for automobiles] - The anode group and the cathode group can be manufactured using the anode group mold 8 and the cathode group mold 9 in the on-mold process, and the anode group mold 7 and the cathode group mold 8 have water cooling pipes. 9 can be built-in.
