Convenient-to-maintain bus-bar cast-welding mould capable of beating heated quickly

Abstract

The invention relates to a convenient-to-maintain bus-bar cast-welding mould capable of being heated quickly. The convenient-to-maintain bus-bar cast-welding mould capable of being heated quickly comprises a mould body, wherein the mould body comprises a plurality of forming units which are arranged on the surface for casting a bus-bar; each forming unit consists of a positive electrode concave path, a negative electrode concave path and a gap bridge concave path for enabling the positive electrode concave path to communicate with the negative electrode concave path; the positive electrode concave paths and the negative electrode concave paths of adjacent forming units are mutually staggered; the forming units are mutually independent; ends, close to each other, of adjacent two forming units are connected through a hook joint structure which comprises a left hook and a right hook, wherein the left hook and the right hook are correspondingly arranged at ends of adjacent two forming units, the left hook and the right hook are correspondingly hooked for tightly connecting adjacent two forming units into an integer so as to define a gap channel; and the forming units can be detachablymounted on the surface of the mould body through fixing structures. The convenient-to-maintain bus-bar cast-welding mould capable of being heated quickly is simple in structure, is convenient in maintenance, is high in heating or cooling speed, and can effectively improve cast-welding quality.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a busbar casting and welding mold which is convenient for maintenance and quick in heating. Background technique [0002] Cast welding is a crucial process in the assembly process of lead-acid batteries, which can weld multiple battery cells to form a complete battery group. The formation of the battery bus bar requires the battery cells to be fixed in the fixture first, and then the bus bar is formed on the tabs of the battery cells using a casting and welding mold, and then the positive bus bar and the negative bus bar between adjacent battery cells are connected. The busbars are soldered. Generally, an automatic busbar casting and welding machine is used to realize automatic casting and welding. The casting and welding machine includes a casting and welding mold. The surface of the casting and welding mold is provided with a casting groove. Spray the casting and welding mold ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, most of the molds used for casting and welding busbars are integrated molding structures. Once a molding unit is worn or damaged, the entire mold needs to be removed for maintenance or scrapped. The casting and welding mold of the structure is designed as independent split modules, but it cannot solve the problem of how to connect the modules to ensure fast and uniform heating or cooling, especially the need to ensure that the spray coolant does not splash into the lead liquid of the forming unit
