The utility model relates to the field of cast-rolling production of aluminum alloy plate strips, in particular to a casting mouth plate for improving the quality of cast-rolled plate strips, which comprises an upper casting mouth plate and a lower casting mouth plate, a large abdominal cavity and a small abdominal cavity are arranged between the upper casting mouth plate and the lower casting mouth plate, and the small abdominal cavity is arranged at one end of a lip edge of a casting mouth. The upper end face of the transition cavity is a slope face, the lower end face of the transition cavity extends to the lip edge of the casting lip to form a plane, a step face is arranged at the joint of the lower end of the transition cavity and the large cavity, the aluminum alloy solution forms a stirring-like effect through the effect that the step face forms a spoiler, and then heavy metal deposition is prevented. And meanwhile, the temperature of the aluminum alloy solution is uniform, the thickness of the lower c
