DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the embodiments and drawings: Embodiment 1

[0017] like Figure 1 and Figure 2 As shown, a liquid discharge port 12 is provided on the furnace wall 11 and passes through the furnace wall 11. The liquid zinc alloy flows from the liquid discharge port 12 of the furnace wall 11 into the chute 21 and then flows into the casting distributor. The chute 21 is a rectangular parallelepiped, and a convex-shaped groove is provided in the chute 21. The convex-shaped groove has a small front end and a large rear end. The small end of the convex-shaped groove passes through the chute 21, and the large end of the convex-shaped groove is connected to the casting distributor. The convex-shaped groove includes a liquid passing groove 22 and a temporary storage groove 23. Both the liquid passing groove 22 and the temporary storage groove 23 are rectangular grooves. Since the width of the liquid passing groove 22 is smaller than the width of the temporary storage groove 23, the small end of the convex-shaped groove is the liquid passing groove 22, and the large end of the convex-shaped groove is the temporary storage groove 23.

[0018] The chute 21 is provided with a through mounting hole, in which a tubular chute spout 4 is fixedly connected. One end of the chute spout 4 passes through the mounting hole on the chute 21 and extends into the temporary storage tank 23. The casting distributor comprises a shell 31 and a casting pipe 32. The shell 31 is a hollow rotating body, and a through mounting hole is provided at the bottom of the shell 31. A bearing is provided at the mounting hole, and the outer side of the bearing is fixedly connected to the inner side of the shell 31, and the inner side of the bearing is connected to the outer side of the chute spout 4 by interference fit. The other end of the chute spout 4 passes through the bearing and extends into the shell 31 of the casting distributor. Since one end of the chute spout 4 is fixedly connected to the chute 21, and the other end of the chute spout 4 is connected to the inner side of the bearing of the casting distributor by interference fit, the casting distributor can rotate around the chute spout 4. One end of the temporary storage tank 23 is connected to the liquid passing tank 22, and the other end of the temporary storage tank 23 is connected to the hollow shell 31 of the casting distributor through the chute spout 4. The casting tube 32 is in the shape of a circular tube. A plurality of casting tubes 32 are evenly distributed in the circumferential direction of the top of the shell 31 , and each casting tube 32 is connected to the shell 31 .

[0019] like Figure 3 and Figure 4 As shown, a cylindrical sleeve 33 is also provided on the top of the shell 31, and the sleeve 33 is fixedly connected to the outer side wall of the top of the shell 31. One end of the cylindrical rotating shaft 6 is fixedly connected to the servo motor in the control assembly 5, and the other end of the rotating shaft 6 is fixedly connected to the sleeve 33. Starting the servo motor in the control assembly 5 can drive the casting distributor to rotate around the chute mouth 4 through the rotating shaft 6, and the liquid zinc alloy in the casting distributor flows out from the casting pipe 32 with the lowest height in the casting distributor. An alloy ingot mold 92 is provided below the casting pipe 32, and an ingot casting unit 91 is provided below the alloy ingot mold 92. A conveying chain or conveying belt is also provided between the alloy ingot mold 92 and the ingot casting unit 91. The conveying chain or conveying belt drives multiple alloy ingot molds 92 to move slowly on the ingot casting unit 91, and the casting distributor also rotates slowly. The liquid zinc alloy flows out of the separated casting tubes 32 into the separated alloy ingot molds 92, so that the liquid zinc alloy will not flow into the gaps between the separated alloy ingot molds 92, and the liquid zinc alloy will flow into the alloy ingot molds 92, thereby avoiding waste of the liquid zinc alloy.

[0020] The plug 7 is in the shape of a hollow truncated cone with an opening at the bottom. The diameter of the bottom of the plug 7 is larger than the diameter of the top of the plug 7. The plug 7 is placed in the liquid discharge port 12 and is supported by a liquid blocking rod. The liquid blocking rod includes a long rod 81 and a cone 82. The long rod 81 is in the shape of a rectangular parallelepiped or a cylinder. The length of the long rod 81 is greater than 1.5 meters. The cone 82 is in the shape of a solid truncated cone. The shape and size of the cone 82 match the hollow part of the plug 7. The long rod 81 is seamlessly connected to the cone 82. The cone 82 of the liquid blocking rod extends from the bottom of the plug 7 into the hollow part of the plug 7, and the cone 82 of the liquid blocking rod is against the inner wall of the plug 7, so that the plug 7 will not be washed away by the liquid zinc alloy flowing out of the liquid discharge port 12.

[0021] like Figures 1 to 4 As shown, to ensure that the liquid zinc alloy does not flow into the gap between the separated alloy ingot molds 92, it is important to control the liquid level of the liquid zinc alloy in the temporary storage tank 23 so that the liquid zinc alloy only flows out of the casting pipe 32 with the lowest height from the casting distributor, and no more than two casting pipes 32 will flow out the liquid zinc alloy at the same time. To control the liquid level of the liquid zinc alloy in the temporary storage tank 23, the flow rate of the liquid zinc alloy in the liquid discharge port 12 must be controlled.

[0022] In this embodiment, the worker holds the plugging rod and uses the cone 82 of the plugging rod to hold the plug 7, and observes the height of the liquid level of the liquid zinc alloy in the temporary storage tank 23. When the liquid level of the liquid zinc alloy in the temporary storage tank 23 is too high, the worker pushes the plugging rod forward to reduce the distance between the plugging rod 7 and the liquid outlet 12, and reduce the flow of the zinc alloy at the liquid outlet 12, until the liquid level of the liquid zinc alloy in the temporary storage tank 23 drops to the standard height. When the liquid level of the liquid zinc alloy in the temporary storage tank 23 is too low, the worker moves the plugging rod slightly backward, so that the plugging rod 7 moves a smaller distance toward the cone head of the plugging rod under the impact force of the liquid zinc alloy, thereby expanding the distance between the plugging rod 7 and the liquid outlet 12, and increasing the flow of the zinc alloy at the liquid outlet 12, until the liquid level of the liquid zinc alloy in the temporary storage tank 23 rises to the standard height.

[0023] In addition, since the speed at which the alloy ingot mold 92 moves on the ingot casting unit 91 and the speed at which the casting distributor rotates are constant, by controlling the flow rate of the liquid zinc alloy in the casting tube 32, the amount of liquid zinc alloy flowing into each alloy ingot mold 92 can be made roughly the same. To control the flow rate of the liquid zinc alloy in the casting tube 32, it is mainly necessary to control the height of the liquid level of the liquid zinc alloy in the temporary storage tank 23. Therefore, in this embodiment, the flow rate of the liquid zinc alloy at the discharge port 12 and the height of the liquid level of the liquid zinc alloy in the temporary storage tank 23 are controlled by the plug 7 to ensure that the amount of liquid zinc alloy flowing into each alloy ingot mold 92 is similar, and to avoid the liquid zinc alloy flowing outside the alloy ingot mold 92 and causing waste.

[0024] Obviously, without departing from the principle of the present invention, several improvements or modifications made should be regarded as within the protection scope of the present invention.
