Cast welding mould of storage batteries

Abstract

The invention discloses a cast welding mould of storage batteries, comprising a mould body, wherein a plurality of casting units are distributed on the surface of the mould body, the plurality of casting units are arranged in sequence to form an upper group and a lower group, each casting unit is composed of two concave casting passages arranged side by side, two close concave casting passages among the adjacent casting units in the same group are communicated by a first concave bridging passage, one of the two residual concave casting passages in the former group of casting units is communicated with the corresponding concave casting passage in the other group of casting units by a second concave bridging passage, and bent parts are arranged on both of the first concave bridging passage and the second concave bridging passage. By means of the cast welding mould of the storage batteries, positive current collection bars and negative current collection bars of adjacent battery monomers can be directly connected in a current collection bar forming procedure of the storage batteries, thereby omitting a successive battery monomer connecting procedure, greatly improving the working efficiency and reducing the production cost.

Description

Technical field [0001] The invention belongs to the field of casting and welding molds, and specifically refers to a casting and welding mold used for forming the collector row of a lead-acid battery. Background technique [0002] The connection process of the lead-acid battery plate is completed by welding, but there are multiple independent working single cells inside the battery. These single cells have the same structure, and they all include the positive plate and the negative plate. Manual welding requires a lot of labor, low production efficiency, and low welding quality. Therefore, a special casting and welding mold is needed for welding. There is a new type of lead-acid battery product with a structure such as figure 1 Shown: The battery box contains six battery cells 01. Each battery cell 01 is made up of several positive and negative plates. After being welded by a casting and welding mold, the positive plate on each battery cell 01 The tabs are connected to form a po...

AI Technical Summary

Problems solved by technology

[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, the production efficiency is very low, and the welding quality is low, so a special casting and welding mold is required for welding work

There is a new type of lead-acid battery product, its structure is as follows figure 1 Shown: The battery box contains six battery cells 01, and each battery cell 01 is composed of several positive and negative plates interlaced. The tabs are connected to form a positive collector bar 02, and the tabs of the negative plate are connected to form a negative collector bar 03, and a pole 04 is formed at one end of the positive collector bar 02 and the negative collector bar 03 for two adjacent batteries The series connection between the monomers 01, therefore, after each manifold forming process, it is necessary to carry out the monomer connection process to connect the poles as a whole. The increase of this process results in a longer battery production cycle and a lower production efficiency; In order to make the above-mentioned new lead-acid battery products adapt to fully automated production, save costs to the greatest extent, and ensure the welding quality of battery pole pieces, it is necessary to improve the existing casting and welding molds to obtain the best use effect.
