During the production process of lead-acid batteries, the pole ears of the positive and negative plates need to be welded together. Generally, the welding cavity in the casting and welding mold needs to be filled with lead liquid first, and then the pole group pole ears are inserted into the welding cavity for welding; then cooling water is passed through the casting and welding mold to cool the lead liquid. During the cooling and solidification process of the lead liquid, the pole ears of the pole group are cast and welded together, and finally the pole group is taken out.
