Problems solved by technology

However, the existing casting and welding mold is a solid steel plate, and the surface of the steel plate is provided with casting grooves. After the steel plate is immersed in the lead liquid pool, the temperature rises, and it takes a long time to wait for the lead liquid to cool and solidify, resulting in low production efficiency. Stress concentration is prone to occur during cooling

Abstract

The invention discloses a cast welding die for an accumulator busbar, belongs to the field of accumulator processing, and is used for solving the technical problem that the heat dissipation capability of a cast welding die is not good in the prior art. The cast welding die for the accumulator busbar, disclosed by the invention, comprises a die body; the upper surface of the die body is provided with multiple groups of molding units used for pouring the accumulator busbar; each molding unit comprises anode concave channels and cathode concave channels arranged side by side; hollow holes are formed in part of areas, located outside the molding units, on the upper surface of the die body; the hollow holes downwards penetrate through the die body. The cast welding die disclosed by the invention is applied to busbar cast welding machines.

Description

【Technical field】 [0001] The invention relates to a casting and welding mold for battery bus bars. 【Background technique】 [0002] Battery is a kind of battery, its function is to store limited electric energy and use it in a suitable place, especially lead-acid battery has been widely used in power generation, lighting, transportation and other fields. There are multiple battery cells that work independently inside the battery, and the multiple battery cells need to be connected by welding to form a complete battery group. Generally, the forming process of the battery bus bar is as follows: firstly, the battery cells are fixed in the fixture, and the bus bar is formed on the tabs of the battery cells using a casting and welding mold, and then the positive connection between the adjacent battery cells is manually fixed. The bus bar and the negative bus bar are soldered. In the prior art, automatic casting and welding is realized by an automatic busbar casting and welding m...
