Embodiment Construction

[0021] Such as Figure 4~6 As shown, a battery plate casting and welding mold, its body 1 includes two separate positive electrode templates 11 and negative electrode templates 12 .

[0022] Both the positive template 11 and the negative template 12 are provided with handles 2, and the positive template 11 is provided with 6 confluence grooves 3 and 6 penetrating hollow parts 5. The confluence groove 3 is provided with pole pits 4, and the hollow parts 5 are rectangular holes. Confluence grooves 3 and hollow parts 5 are alternately arranged horizontally, and confluence grooves 3 and hollow parts 5 are alternately arranged vertically. One confluence groove 3 and one hollow part 5 are arranged horizontally. Three confluence grooves 3 and three hollow parts 5 are respectively provided, and positioning holes 7 are provided around the positive electrode template 11 .

[0023] The negative electrode template 12 is provided with 6 confluence grooves 3 and 6 hollowed-out parts 5, the...

Abstract

The invention relates to a cast-weld mold for a storage battery electrode plate, which comprises a body (1) and handles (2), wherein busways (3) internally provided with electrode post holes (4) are formed in the body (1); the body (1) is formed by a positive electrode template (11) and a negative electrode template (12) that are split; through hollow parts (5) are arranged on the positive electrode template (11) and the negative electrode template (12); the busways (3) and the hollow parts (5) on the positive electrode template (11) and the negative electrode template (12) are arranged transversely and alternately; the busways (3) and the hollow parts (5) on the positive electrode template (11) and the negative electrode template (12) are arranged longitudinally and alternately; and positions of the busways (3) and the hollow parts (5) on the positive electrode template (11) are opposite to those of the busways (3) and the hollow parts (5) on the negative electrode template (12). According to the cast-weld mold, structural gaps among electrode lugs and busbars can be reduced effectively, the performance of a storage battery can be optimized, and the life of the storage battery can be extended.

Description

technical field [0001] The invention belongs to the technical field of casting and welding of storage battery metal pole plates or the like, and in particular relates to a casting and welding mold of battery pole plates. Background technique [0002] The vast majority of batteries are composed of plastic shells and several single cells installed in them. Each single cell is made of positive and negative plates alternately stacked, and several layers of insulation are used between the positive and negative plates. separated by fiberglass paper. Several positive plate lugs and several negative plate lugs on the battery cell are respectively formed into a positive bus bar and a negative bus bar with poles through a casting welding process, and then the adjacent single cells are sequentially connected to each other by electric welding. The positive and negative poles of the battery are welded together to form a battery pack composed of several single cells connected in series. ...
