In the embodiment of the invention, the float bowl lifting driving mechanism comprises a servo electric cylinder I10 and a transmission connecting rod I15, wherein one end of the transmission connecting rod I15 is connected with the output end of the servo electric cylinder I10, and the other end of the transmission connecting rod I15 is connected with the top of the liquid level stabilizing float bowl 8.

On the basis of the above embodiment, as shown in fig. 1 to 3, the quantitative pouring device for nonferrous metal cast ingots further comprises a cap-shaped liquid level stabilizing floating disc 7 and a floating disc lifting driving mechanism, wherein the cap-shaped liquid level stabilizing floating disc 7 is sleeved outside the liquid level stabilizing buoy 8 and can slide relative to the liquid level stabilizing buoy 8; the floating plate lifting driving mechanism is arranged on the outer side of the furnace box 1, is connected with the cap-shaped liquid level stabilizing floating plate 7 and is used for driving the cap-shaped liquid level stabilizing floating plate 7 to lift.

In the embodiment of the invention, the floating disc lifting driving mechanism comprises a servo electric cylinder II 14 and a transmission connecting rod II 9, wherein one end of the transmission connecting rod II 9 is connected with the output end of the servo electric cylinder II 14, and the other end of the transmission connecting rod II 9 is connected with the cap-shaped liquid level stabilizing floating disc 7. Specifically, servo electric cylinder I10 and servo electric cylinder II 14 are arranged at the rear side of the furnace box 1, and the casting ladle 2 is arranged at the front side of the furnace box 1 through a supporting shaft. An ingot mould 3 is arranged below the outer side of the casting spoon 2, and a casting liquid level sensor 12 is arranged above the ingot mould 3. The ingot moulds 3 can move continuously through the transmission of a conveyor belt, each ingot mould 3 can move to the lower part of a casting gate in sequence, and leave to enter the next station in sequence after the casting is finished.

Further, a furnace liquid level sensor 4 is arranged in the furnace box 1. In this embodiment, four in-furnace liquid level sensors 4 are arranged at four corners of the furnace box 1.

In the embodiment of the present invention, as shown in fig. 3, the rotation driving device comprises a servo motor 11, and an output end of the servo motor 11 is in transmission connection with the casting ladle 2 for driving the casting ladle 2 to rotate around a supporting shaft 13.

Can servo control servo electric cylinder I10's length, and then drive transmission connecting rod I15 and drive liquid level stabilization buoy 8 and reciprocate, its effect is the height of control liquid level, is controlled by the liquid level sensor 4 feedback liquid level height in the stove. Therefore, the average height of the liquid level is controlled by driving the transmission connecting rod I15 to drive the liquid level stabilizing buoy 8 through the servo electric cylinder I10. When the average height of the liquid level is reduced, the liquid level stabilizing buoy 8 can be controlled to move downwards to raise the height of the liquid level, otherwise, when the average height of the liquid level is raised, the liquid level stabilizing buoy 8 can be controlled to move upwards to lower the height of the liquid level, and the purpose of controlling the height of the liquid level is achieved.

In order to meet the requirement of quantitative pouring, the invention starts from two aspects, on one hand, the liquid level in the furnace is stabilized, the liquid level is controlled by the floating and sinking of the liquid level stabilizing buoy 8 in the molten metal 5, and the liquid level is fed back by the liquid level sensor 4 in the furnace; on the other hand, the weight of the cast liquid is controlled, and the quantitative casting is realized by controlling the casting ladle 2 through the servo motor 11 and combining the casting liquid level sensor 12 above the ingot mould 3.

This is repeated to complete the metal quantitative casting of a series of ingot molds 3 on the conveyor belt.

As the metal melt 5 is continuously scooped up by the ladle 2, the level thereof drops, and each time the ladle 2 is immersed in the metal melt, fluctuation of the level is caused, which affects the casting quality. The invention adjusts the liquid level change by matching the cap-shaped liquid level stabilizing floating disc 7 and the liquid level stabilizing floating barrel 8. The four total in-furnace liquid level sensors 4 are arranged above the molten metal and are respectively positioned at four corner positions of the furnace box 1, so that the heights of the liquid levels of the four points can be measured in real time, and the average height of the liquid level and the wave crests and the wave troughs of the standing waves of the liquid level can be obtained through data analysis and processing.
