Description
Technical Field
The utility model belongs to the technical field of lead acid battery polar plate and busbar cast joint, concretely relates to reduce cast joint mould device in battery confluence hole.
Background
The cast welding of the storage battery is an important process in the manufacturing process of the battery, and the polar plate and the bus bar need to be cast welded and connected to form a polar group in the production, assembly and manufacturing process of the battery. During cast welding, in order to ensure that the polar plate and the bus bar are welded to have a good welding joint, the positions of the plate lugs are brushed with soldering flux before the polar plate is cast welded, but the use of the soldering flux can cause the bus vent holes. In the process of cast-weld, if bubbles formed along with the evaporation of the soldering flux at high temperature cannot escape before the alloy is solidified, air holes are formed at the interface of the pole lug and the bus bar, and the bus bar is not welded firmly due to excessive air holes. In the use process, the sulfuric acid corrodes the bonding interface of the polar plate and the bus along the air hole, so that the battery bus is corroded and broken, and the battery fails.

In the figure: 1. an acoustic wave generator; 2. a support; 3. a protective groove; 4. a wire; 5. a high frequency power supply; 6. casting and welding a mould; 7. a bus bar; 8. a pole group.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the utility model relates to an embodiment of a cast joint mould device for reducing battery confluence exhaust hole, including cast joint mould 6, acoustic generator 1, support 2, protection groove 3, wire 4 and high frequency power supply 5 constitute the sound wave generating device of vibratile cast joint mould 6.
The cast-on mould 6 is a conventional cast-on mould having four sides for cast-on connection of the plates in the plate group 8 to form the busbar 7.
The protective groove 3 is a rectangular groove having one side surface and one end surface opened or opened. One side of the open end surface of the protective groove 3 is fixed to one side surface of the cast-weld mold 6. The protective groove 3 may be installed on four sides of the mold according to the structure of the cast-weld mold 6. The protective groove 3 is screwed to one side surface of the cast welding mold 6. The sound wave generator 1 is arranged in the protective groove 3 through a bracket 2, and the bracket 2 is used for supporting the sound wave generator 1. The lower part of the bracket 2 is fixedly connected with the bottom of the protective groove 3. The protective groove 3 plays a role of protecting the sound wave generator 1, and can prevent the sound wave generator 1 from being damaged by splashing of high-temperature alloy lead liquid, so that the protective groove 3 has certain high-temperature resistance.
