[0002] In casting production, a pouring device is generally used to tilt the casting ladle containing the molten material, that is, to raise one end of the casting ladle so that the other end of the casting ladle can pour the molten material into the casting mold.

[0003] For example, CN 209811216 U discloses a quantitative casting device, including a frame, a tundish with an arc-shaped bottom, an arc-shaped support plate for carrying the tundish and rotatable around a first axis, a first driving mechanism for driving the arc-shaped support plate, a casting ladle with a flat bottom and rotatable around a second axis, a weighing sensor for weighing the casting ladle, a flat support plate for carrying the casting ladle and rotatable around a third axis, a second driving mechanism for driving the flat support plate, and a control unit for driving the first driving mechanism or the second driving mechanism to start and stop according to a signal from the weighing sensor. The second driving mechanism and the flat support plate and other peripheral components of the device form a pouring structure for the casting ladle. When the second hydraulic cylinder of the second driving mechanism extends upward, the flat support plate is driven to rotate, and the flat support plate drives the casting ladle to rotate synchronously, thereby pouring the copper liquid into the mold. However, the dumping structure has the following problems: 1. The fixed structure is not conducive to movement. When the mold position is far away from the tundish position, it is not convenient to transport the molten material over long distances; 2. The casting ladle that carries the molten material is heavy. During the dumping process, the center of gravity tilts forward, causing connection pressure with the flat support plate, posing a great safety risk. Utility Model Content
