[0074] The mold closing assembly 232 is arranged opposite to the mold opening assembly 233, and the mold opening assembly 233 is arranged on the side facing the discharging and carrying device 7. When the cast-welding mechanism 22 is rotated to the mold closing assembly 232 by the circular turntable mechanism 21, the pull plate 2324 driven by the first positioning cylinder 2323 of the mold closing assembly 232 pulls the positioning push plate 2241 on the cast-welding mechanism 22, and then the positioning push plate 2241 drives the positioning rod 224 to be separated from the positioning hole 2221, and the positioning rod 224 is supported by the mold closing branch plate 2322 and the lifting support rod 2222.

[0075] With the above structure, when the lead-acid battery pole group is cast-welded, the lead-acid battery pole group coated with the cast-welding agent is carried by the cast-welding agent coating device 6 to the bearing plate 223 above the lead pouring furnace 4 after the brush cutting operation of the brush cutting device 8 and the soldering agent coating operation of the soldering agent coating device 6. The cast-welding mechanism 22 is fixed on the circular turntable mechanism 21, and the circular turntable mechanism 21 is driven to intermittently drive the circular rotation of the cast-welding mechanism 22, so that the cast-welding mechanism 22 can move along the circular turntable mechanism 21 in an intermittent circular manner. The preheating of the cast-welding mold 225 passing through is realized by the radiation heating device 5 on one side of the lead pouring furnace 4, so as to prevent the solidification of the lead liquid poured into the cast-welding mold 225 from the lead pouring furnace 4, which affects the flowability of the lead liquid. After the lead liquid is poured by the lead pouring furnace 4, the cast-welding mold 225 and the lead liquid are heated again by the radiation heating device 5 on the other side, so as to ensure the flowability of the lead liquid and the cast-welding effect. Then, the lead-acid battery pole group on the bearing plate 223 is driven into the cast-welding mold 225 by the mold closing assembly 232 to be in contact with the lead liquid for cast-welding. During this period, the cooling device 3 is used to blow and cool the cast-welding mold 225 and the lead liquid, so as to facilitate the cooling and forming of the lead liquid to complete the cast-welding. The cast-welded lead-acid battery pole group is demolded by the mold opening assembly 233, and then the cast-welded lead-acid battery pole group is carried out by the discharging and carrying device 7, so as to be ready for subsequent cast-welding operation.
