Improved structure of battery cast welded mold

Abstract

The invention discloses an improved structure of a battery cast welded mold, comprising a cast welded mold body. A plurality of forming structures for casting a current-collecting bar are distributed on the surface of the cast welded mold body in sequence; each formed structure consists of a positive electrode groove and a negative electrode groove; positions of a positive electrode groove and a negative electrode groove which are arranged in an adjacent forming structure are arranged in a staggered way, wherein the negative electrode groove or the positive electrode groove in the forming structure is correspondingly connected with the positive electrode groove or the negative electrode groove in the adjacent forming structure into an integral structure, so that the structure of the surface of the cast welded mold can be greatly simplified, cast welding working procedures can be reduced, the welding efficiency can be improved and the production cost can be saved to the maximum extent while ensuring the welding quality.

Description

technical field [0001] The invention relates to a casting and welding mold, in particular to a casting and welding mold for forming a lead-acid storage battery collector. Background technique [0002] The lead-acid battery plate connection process is completed by welding, but there are multiple single-working single cells inside the battery. These single cells have the same structure, including positive and negative plates. If manual welding is used, the labor force is large and the production efficiency is very low, but the welding quality of the battery is not high, so a special casting and welding mold is required for welding. Such as figure 1 As shown, the currently known battery casting mold has concave grooves 01 formed by battery current collectors. The concave grooves 01 are distributed in parallel up and down. After the battery lugs are inserted into the concave grooves, a negative current collector and a positive current collector are formed. Row. The groove gro...

Problems solved by technology

The groove groove corresponding to each battery cell is independent and separated, and a pole groove 02 needs to be provided at the end of the groove groove to connect two adjacent battery cells in series, so in each current collector forming process Finally, a monomer connection process is required to connect the poles as a whole. The increase in this process results in a longer battery production cycle and a lower production efficiency; the setting of the pole groove increases the amount of lead used for casting and welding, resulting in an increase in the internal resistance of the battery , while the production cost increases, the product quality cannot be guaranteed
