Description

Technical Field

[0001] The utility model belongs to the technical field of vacuuming and acid adding of lead-acid batteries, and in particular relates to a grid continuous casting machine for lead-acid batteries. Background Art

[0002] The main functions of the grid in a lead-acid battery are, on the one hand, to conduct and collect current, ensuring uniform current distribution, and, on the other hand, to support the active material. The grid serves a dual function as both a conductive framework and a carrier for the active material. Currently, lead-acid battery grids are cast using continuous casting machines. Patent document CN202224618U discloses a continuous casting apparatus for lead grids, comprising a frame, a movable mold, and a fixed mold that cooperate with each other for casting. The frame comprises a table, a support frame, and a chassis. The movable mold is a hollow cylinder with a grid-like cavity on its surface and an inner cylinder inside. The cavity contains the die that forms the grid and the tabs. The inner cylinder forms a sealed, heated chamber with the inner wall of the movable mold. The movable mold is connected to the bearing frame via bearings, which are in turn connected to the frame's table. The fixed mold is elastically connected to the frame's table and mates with the movable mold via a curved surface on one side. Although this patent can cast lead plates with grids and tabs in one go, it cannot promptly process the waste gas generated during the continuous casting process (for example, when the continuous casting machine is in use, it sprays high-pressure, high-temperature protective gas to isolate the air and prevent the lead liquid from oxidizing, and to blow away excess liquid in the mold cavity to ensure normal filling. However, the gas is directly discharged after use, and the gas has a certain odor. The odor after discharge will affect the surrounding environmental hygiene). This causes certain pollution to the environment and is not conducive to production. Therefore, a lead-acid battery grid continuous casting machine is needed to solve the above technical problems.
