A battery casting and welding mold

Abstract

The invention discloses a cast welding die for a storage battery, which belongs to the field of storage batteries. According to the cast welding die, the problem that a die is easy to break off is solved. The cast welding die comprises an upper plate and a lower plate, wherein the upper plate can be buckled with the lower plate; after the upper plate is mutually buckled with the lower plate, an inner cavity is formed by the lower surface of the upper plate and the upper surface of the lower plate; two upper reinforcing parts are respectively arranged on two sides of the upper plate; the upper reinforcing parts and the upper plate form an integrated structure; the lower surface of the upper plate is a polished surface; two lower reinforcing parts are respectively arranged on two sides of the lower plate; the lower reinforcing parts and the lower plate form an integrated structure; the upper surface of the lower plate is a polished surface; a plurality of mounting columns are arranged on the lower surface of the upper plate; a plurality of mounting seats are arranged at the positions corresponding to the mounting columns, of the upper surface of the lower plate. The lower surface of the upper plate and the upper surface of the lower plate are kept as the polished surfaces, so that the step of processing reinforcing ribs is eliminated and cutting scars caused by cutting of the reinforcing ribs are avoided while the cost is reduced; the reinforcing parts are respectively and additionally arranged on two sides of each of the upper plate and the lower plate so as to make up the strength loss caused by the reinforcing ribs.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a casting and welding mold for storage batteries. Background technique [0002] The battery casting and welding molds in the existing technology are generally divided into an upper plate and a lower plate. The upper surface of the upper plate is provided with a number of forming units for casting the current collector. In order to ensure the strength of the mold during the casting and welding process, the lower plate of the upper plate There are several ribs on the surface and the upper surface of the lower plate. In order to ensure firmness and save costs, the ribs are integrally formed with the upper plate or the lower plate. Or cutting scars are left on the upper surface of the lower plate and the corresponding reinforcing ribs, causing the mold to break easily along these scars after long-term use. Contents of the invention [0003] The purpose of the present invention is ...
