[0002] In the casting and welding process of the lead-acid battery manufacturing process, the battery pole group is usually turned upside down on the busbar mold soaked with lead liquid, and the pole ear is inserted into the lead liquid in the mold cavity for casting welding. After the busbar mold is cooled, the battery bottom box is removed from the busbar mold. When cooling the busbar mold, all parts of the lead liquid in the busbar mold cavity must be cooled evenly. If a part is not cooled evenly, it may not be cooled enough to be demolded, or it may cause a cold weld in that part. The current cooling methods all use one of water cooling or air cooling, such as the utility model patent with application number CN202023103720.0 and the name of "A water cooling mechanism for cast welding of lead-acid batteries". A cooling circulation box is set up, and a top column for resisting the cast welding mold is provided in the cooling circulation box.

The distribution route of the water spray holes corresponds to the bus mold cavity to cool the mold cavity. These all use water cooling. The utility model patent with application number CN03274608.3 and title “Small valve-controlled sealed lead-acid battery casting and welding equipment” has a cooling device composed of a flat plate with air ducts and air holes, a drive chain, and a fan; the invention application with application number CN202311272406.0 and title “A mold circulation system and a lead-acid battery casting and welding line using the system” has a fan and several air guide channels connected to the fan for guiding air and cooling the mold unit on the cooling casting and welding station, and the air outlet end of the air guide channel is provided with several air outlet holes, and the distance between adjacent air guide channels is matched with the distance between two adjacent groups of mold units, so that during the intermittent forward conveying of the casting and welding mold, the end of the air guide channel is just aligned with the bottom of the casting and welding mold, thereby improving the cooling efficiency of the casting and welding mold, and then improving the production efficiency, and both adopt air cooling. However, in the above structure, the cooling method is determined and cannot be selected according to needs. Utility Model Content

The external cold source enters the cooling pipe from the cold source inlets at both ends, and then flows out along the cooling holes to the outer surface of the mold cavity, so that the lead liquid in the cavity is evenly cooled.

[0005] Furthermore, two mounting plates are arranged in parallel in the slag frame, and two ends of the cooling pipe are arranged on the two mounting plates respectively.

[0006] Furthermore, both ends of the mounting plate are connected to the slag frame. By arranging the mounting plate on the slag frame at both ends, the middle part of the mounting plate and the cooling pipe are both suspended, which facilitates the circulation of the cooling material.

[0007] Furthermore, a connecting pipe is provided at the mounting plate, and the cooling pipe is connected to an external cold source through the connecting pipe.

[0008] Furthermore, a collecting bucket is provided below the slag frame. When water cooling is adopted, the cooling water flowing out of the cooling hole is collected by the collecting bucket.

[0009] Furthermore, the bottom edge of the slag frame is connected to the top edge of the collecting bucket to ensure that cooling water does not leak from the bottom of the slag frame.

[0010] Furthermore, after the connecting pipe passes through the collecting bucket, both ends are connected to the cooling port and the external cooling source respectively.

Figure 2As shown, the cooling device includes a square slag frame 1, and the range surrounded by the slag frame 1 should include the horizontal space below the mold 200 to ensure that each mold cavity 200 can be cooled. Two parallel mounting plates 2 are arranged in the slag frame 1, and the mounting plates 2 are arranged on the slag frame 1 at both ends, and an array of cooling pipes 3 is arranged between the two mounting plates 2, and the cooling pipes 3 are arranged on the mounting plates 2 at both ends. In this way, except for the two ends of the mounting plates 2 and the cooling pipes 3, the rest of the parts are overhead structures to facilitate conversion into a water-cooled structure.

[0029] like Figure 3-Figure 5 As shown, in this embodiment, each group of cooling pipes 3 consists of two, one group corresponds to the bottom of a cavity of the mold 200, and directly cools the cavity. Figure 6 As shown, the cooling tube 3 is a hollow tube, and a cooling hole 31 is provided on the side facing the mold 200. After the cold air enters from both ends of the cooling tube 3, it is ejected along the cooling hole 31 and sprayed onto the outer surface of the mold cavity 200 to cool down. Figure 3 As shown, through holes 21 are evenly arranged on the mounting plate 2, and a connecting pipe 4 is fixed at the bottom of the mounting plate 2 to communicate with the external cold air. The connecting pipe 4 is also a hollow tube. One connecting pipe 4 is paired with one through hole 21, and one through hole 21 corresponds to one end of a group of cooling pipes 3.

[0030] like Figure 7 As shown, in this embodiment, one end of a group of cooling pipes 3 is fixed to a mounting plate 2 by a connector 8, such as Figure 8 and Fig. 9 As shown, a connector 8 includes a fixing tube 81 and a pressing tube 82, the pressing tube 82 is used to limit the two connecting tubes 4, and the fixing tube 81 is used to fix the entire connector 8 on the mounting plate 2. Figure 8 As shown, the pressing tube 82 is a square column structure with a hollow interior. Two side holes 821 are provided on the side facing the connecting tube 4. One connecting tube 4 is inserted into one side hole 821. The surface of the pressing tube 82 in contact with the fixed tube 81 is provided with a bottom hole 822. Of course, it can also be set to a completely empty structure and directly connected to the fixed tube 81. Fig. 9 As shown, the fixed pipe 81 is a flat plate structure, and a connecting hole 811 is provided in the middle thereof, and the connecting hole 811 is aligned with the through hole 21 of the mounting plate 2.

[0032] This embodiment adopts a water-cooling structure. Fig.10 and Fig.11 As shown, a collecting hopper 5 is provided below the slag frame 1, and preferably the upper edge of the collecting hopper 5 is sealed and connected to the slag frame 1, so that the cooling water can be collected by the collecting hopper 5 after being sprayed out from the cooling hole 31 without leaking out. A water tank 6 is provided below the collecting hopper 5. After the cooling water is collected in the water tank 6, it can flow out from the water outlet 7. After being cooled, it can be connected to the connecting pipe 4 through a pipeline for recycling. Fig.10 It can be seen that the connecting pipes 4 in this embodiment all pass through the collecting hopper 5, so each connection position between the connecting pipe 4 and the collecting hopper 5 must be sealed. Therefore, other methods can also be used to connect the connecting pipe 4 to the cooling water pipeline, such as collecting multiple connecting pipes 4 into a larger main pipe and passing through a position of the collecting hopper 5.
