Abstract

The invention discloses a storage battery grid casting die which comprises a die body. A die cavity is formed in the die body. The die body is provided with a casting opening communicating with the die cavity. A breaking device is arranged at the position, close to the casting opening, in the die body. An exhausting channel is formed in one side of the die body. The die cavity communicates with the exhausting channel through an exhausting opening. An air outlet is formed in the exhausting channel. A negative pressure generator is arranged in the air outlet. The storage battery grid casting dieis simple in structure and convenient to operate, the negative pressure generator is arranged, the smoothness in the exhausting process of a grid and mobility of lead liquid can be improved, a special-shaped grid difficult to cast at ordinary times can be cast and formed smoothly, the production efficiency is improved, and the phenomenon of generating grid air holes is avoided.

Description

technical field

[0001] The invention relates to a casting mold, in particular to a battery grid casting mold. Background technique

[0002] In the current battery production process, the casting of the battery grid is an indispensable process, but the existing device only has a casting mold, and the casting liquid is injected manually or mechanically. If the casting liquid is too small, the grid will be defective, and the casting liquid Too much will cause waste of casting liquid; after the grid is cast, the grid must be taken out. There are two ways to take it out. One is to take it manually and the efficiency is low; the other is to push the movable mold through the ejector pin on the fixed mold. , the grid falls automatically, and the efficiency is high, but because the grid has just been cast, it will cause collision damage to the grid during the process of the drop value transfer device, resulting in a defective grid.
