[0032] Further, the adaptive elastic connecting member 4 comprises a connecting plate 401 fixed to the end of the arc-shaped frame 3, one side of the connecting plate 401 is fixedly installed with a limiting rod 402, the outer side of the limiting rod 402 is slidingly connected with a sliding block 403 connected with the buffer frame 5, the sliding block 403 and the connecting plate 401 are connected with a spring 404, one side of the connecting plate 401 is fixedly installed with a first electric push rod 405, the telescopic end of the first electric push rod 405 is fixedly installed with a buffer block 406 in contact with the sliding block 403.
[0033] Further, the pushing distance of the electric push rod 405 is associated with the triggering times of the pressure sensor 15, and the spring 404 is in a stretched state.
[0034] When it is necessary to adjust the distance between the arc-shaped frame 3 and the buffer frame 5 through the elastic connecting member 4, the first electric push rod 405 can be used to push the buffer block 406 to move, so that the sliding block 403 moves, and at the same time the spring 404 is adaptively stretched or relaxed, and the distance between the arc-shaped frame 3 and the buffer frame 5 can be changed by the movement of the sliding block 403.

[0041] Working principle:
[0042] The molten iron flows out through the discharge hopper 1 of the casting machine, reaches the buffer frame 5 under the influence of inertial potential energy, then moves again towards the arc-shaped frame 3 after being buffered by the buffer plate 11 and the spring 404, and reaches the mold under the guidance of the arc-shaped frame 3 to complete casting;
[0043] When the molten iron flow fluctuates, the molten iron flow at the discharge hopper 1 of the casting machine increases, the residence time of the molten iron reaching the buffer frame 5 is prolonged, and the impact caused by the increased flow makes the extrusion amplitude of the buffer plate 11 larger, at this time the pressure value or fluctuation rate at the air pressure sensor 13 reaches the threshold value, thereby activating the adjusting member 12 to adaptively adjust the position of the buffer plate 11;
[0044] After the position of the buffer plate 11 is adjusted, the time of the molten iron flowing in the buffer frame 5 is prolonged, which causes the increase of the gravitational potential energy storage, thereby causing the increase of the splashing amount reaching the arc-shaped frame 3, at this time the pressure sensor 15 acts to adjust the adaptive spring connecting member 4, reduces the relative distance between the arc-shaped frame 3 and the buffer frame 5, thereby reducing the splashing amount, that is, the capacity of the buffer frame 5 can be temporarily increased while the splashing is reduced.
