This invention discloses a high-quality aluminum alloy sheet continuous casting device, belonging to the technical field of casting devices. It includes a worktable with a mounting plate rotatably mounted on it. This design utilizes a push rod. After the sheet material has cooled, the drive assembly rotates the sheet material under the push rod via the mounting plate. As the mounting plate moves the feeding pipe downwards, it further moves the push rod downwards, applying a downward thrust to the sheet material. Under this thrust, the sheet material moves downwards and falls onto a conveyor belt. The conveyor belt then transports the cast sheet to the next process. A spring then drives the top plate to reset and re-seal the casting tank, eliminating the need for time-consuming unloading and demolding. Furthermore, as the mounting plate rotates, the demolded casting tank moves back under the feeding pipe, thus achieving continuous casting and improving production efficiency.
