The utility model provides a slidable mounting plate in the aluminum alloy die-casting device, and each mounting plate constitutes a lower bottom template. After the lower bottom template cooperates with the upper top assembly to die-cast an aluminum alloy die-casting, the respective mounting plates can be driven away from each other by the cooperation of a meshing ring and a first gear, so that the aluminum alloy die-casting can be separated from the inner wall of the lower bottom template, and each mounting plate can share the friction between the surface wall of the die-casting, thereby reducing the problem of surface damage of the die-casting caused by demolding, thereby effectively improving the practicality of the aluminum alloy die-casting device.

[0004] In actual use, during the die-casting process of aluminum alloy, it is necessary to spray the cavity mold with a release agent.
