[0002] The safety locking device of the liquid outlet of the aluminum alloy melting and casting furnace is mainly used to prevent safety hazards caused by the outflow of high-temperature metal during the melting and casting process. The safety locking device of the liquid outlet of the aluminum alloy melting and casting furnace can effectively ensure the safety of the melting and casting process and reduce the risk of accidents.

[0003] According to a publicly disclosed automatic mechanical locking device for securing the water outlet of an aluminum melting furnace's eyelet brick (publication number: CN211782777U), a track is provided on the chute, and a mounting frame is slidably connected to the track via a track pulley. A telescopic cylinder is disposed on one side of the mounting frame, and its cylinder shaft is fixedly connected to the mounting frame, driving the mounting frame to move horizontally on the chute. A propulsion mechanism is fixedly connected to the mounting frame, and its free end is fixedly connected to a plug, which is coaxially arranged with the water outlet of the eyelet brick. When processing aluminum alloys in a casting furnace, molten aluminum is released. During discharge, abnormalities may occur, requiring timely plugging of the liquid outlet. However, the interaction between the mounting frame, track, and other components makes it difficult to provide sufficient hydraulic locking force, making it difficult to prevent water leakage and the occurrence of scalding accidents. This requires improvement. Utility Model Content
