Description

Technical Field

[0001] The utility model belongs to the technical field of plate grid production, and in particular relates to a fixed die installation structure used in plate grid continuous casting. Background Art

[0002] The grid is the main component of the lead-acid battery and the current collecting skeleton of the electrode. It plays the role of conducting, collecting current and making the current evenly distributed.

[0003] At present, the grid is usually formed by the continuous casting process with the help of the cooperation between the fixed mold and the rotating mold. During daily maintenance and equipment downtime, the residual lead liquid in the fixed mold will solidify. Before restarting the production line, the residual lead liquid needs to be cleaned up in time. In order to facilitate the cleaning of the lead liquid in the fixed mold, the fixed mold needs to be disassembled. However, during the repeated disassembly and installation process, the installation structure of the fixed mold will become loose and the fixed mold cannot be pressed, resulting in the shaking of the fixed mold during the production process, affecting the casting quality of the grid.
