う欠点を有していた。Problems to be Solved by the Invention The cast-on-strap manufacturing method described above welds the ears of the electrode plate group using a limited amount of heat from a certain amount of molten lead that forms the straps and pole columns. be. Therefore, even if the surface of the edge of the electrode plate group, which is prone to form an oxide film, is subjected to treatments such as brushing or flux coating, and then immersed in the molten lead in the mold, the surface of the edge of the electrode plate group is Since the welding heat capacity of the ear part of the plate group is large, the volume of the ear part of the electrode plate group immersed in the molten lead (cross-sectional area of the plate group ear part x length of the ear part of the electrode plate group during strap formation) becomes large. Accordingly, the ears of the electrode plate group were difficult to be welded, and only the cut surfaces of the ears cut to a certain height were welded. In order to improve this, the ears of the strap forming part are made thinner, and a convex groove is provided in the strap forming part of the mold that has a concave part, so that the depth of immersion of the ears of the electrode plate group into the mold is reduced. However, there were problems such as a decrease in mechanical strength and corrosion resistance of both the strap and the ear. In this way, the cast-on-strap method connects the pre-cast lead alloy pole poles and the ears of the pole plate group with oxygen.
This method is more complicated than the welding method using a hydrogen gas burner, and has the disadvantage that the weldability of the edges of the electrode plate group is unstable.

特徴とするものである。Means for Solving the Problems In order to achieve the above objectives, in a method for manufacturing lead-acid battery plate groups using a cast-on-strap method in which the plate group ears, straps, and pole pillars are integrally welded, the strap formation The method is characterized in that the depth of immersion into the mold of the ear portion of the electrode plate group that falls over with the knock-out plate provided in the mold of the portion protruding is defined.

This figure shows the state of welding between the ear part 14 and the molten lead metal 9. In a, the immersion depth of the ear part 14 into the mold 3 is uneven, and the volume of the ear part 14 is unstable. , the solidification speed of the molten lead metal 9 is different from that of the ear part 14, and a recess 12 is formed between the ear part 14 and the molten lead metal 9, and a crack is generated from the ear part 14 to the strap 10. b shows the welded state in the present invention, and the ear part 1
4 into the mold 3 is uniform and the solidification rate of the molten lead metal 9 is stabilized. Therefore, since the ear part 14 leaks with molten lead, a buildup occurs between the ear part 14 and the molten lead metal 9. A portion 13 is formed and the welding state is good.
