Description

Technical Field

[0001] This utility model relates to the technical field of aluminum ingot casting equipment, and in particular to a low-slag quantitative casting device. Background Technology

[0002] Aluminum ingots refer to high-purity aluminum metal blocks obtained through smelting and refining processes. During aluminum ingot casting, molten aluminum is poured into a mold using a casting device. However, existing casting devices tend to pour molten aluminum from the outlet into the center point of the mold, preventing it from reaching other parts. Over time, this causes wear at the center point of the mold, reducing its lifespan.

[0003] To address the aforementioned issues, patent document CN213002604U discloses an aluminum ingot casting mold distribution device. This device includes a distribution wheel positioned above the mold assembly and connected to the main channel. The distribution wheel is a hollow cylindrical structure and can rotate along its central axis. Multiple aluminum outlets are formed on the side of the distribution wheel along its circumference, arranged in at least two rows. Each row includes multiple evenly spaced aluminum outlets, and the two rows are staggered. Any two outlets in one row can form an isosceles triangle when connected to a single outlet in the other row. When the distribution wheel rotates along its central axis... When the mandrel rotates, the mold assembly moves synchronously from its original position, and its direction of movement is opposite to the rotation direction of the distribution wheel. When the aluminum outlet at the bottom is poured into the mold located directly below the aluminum outlet, all the molds in the mold assembly are finished being poured. After that, the aluminum ingot is removed, and an empty mold assembly is obtained. The empty mold assembly is arranged in the same order. The empty mold assembly is moved back to its original position in the opposite direction to start a new round of pouring. This ensures that the aluminum outlet at the bottom is the next aluminum outlet in a different row. When pouring into the same mold using this aluminum outlet, the pouring position is different from the pouring position in the previous round.

[0004] However, the above-mentioned distribution device still has the following problems in use: 1. During the aluminum ingot casting process, the amount of molten aluminum flowing into the mold will fluctuate depending on the flow rate of molten aluminum in the ship-shaped chute. In this case, even if a flow control device is used, there will be a certain adjustment delay. Even if the flow rate of molten aluminum is controlled, a few scrap ingots will still appear. 2. When molten aluminum flows from the ship-shaped chute into the distributor and from the distributor into the mold, it falls vertically from top to bottom. During the falling process, it washes over the distributor and the mold, generating a lot of aluminum dross, which not only reduces the quality of the aluminum ingot, but also reduces the service life of the distributor and the mold. Utility Model Content

[0005] This invention provides a low-slag quantitative casting device to solve the technical problems in the prior art where the distribution device is easily affected by fluctuations in the flow rate of molten aluminum, resulting in waste ingots and generating a large amount of aluminum slag during the flow of molten aluminum.

[0006] To solve the above problems, the low-slag quantitative casting device provided by this utility model adopts the following technical solution:

[0007] A low-slag quantitative casting device, comprising:

[0008] A pouring pitcher, which is connected to the flow holes of a boat-shaped chute, and has multiple spouts at its bottom;

[0009] A drive mechanism, the output of which is connected to the pouring jug, for driving the pouring jug to move;

[0010] The detection mechanism is located directly above the mold to detect the liquid level of the molten aluminum inside the mold.

[0011] A controller, connected to the drive mechanism and the detection mechanism, is used to receive liquid level information detected by the detection mechanism and control the drive mechanism to move the pouring jug based on the received information.

[0012] The beneficial effects of the low-slag quantitative casting device provided by this utility model are:

[0013] 1. By setting up a pouring jug connected to the flow orifice of the boat-shaped chute, and setting multiple spouts at the bottom of the jug, molten aluminum can be injected into the same mold through multiple spouts. This reduces the flow rate of molten aluminum per unit time of a single spout while ensuring the overall casting speed, thus avoiding the generation of aluminum slag due to excessive casting speed of a single spout. In addition, n jugs can be arranged in parallel to cast n molds simultaneously. With the total casting time remaining unchanged, the casting time of a single mold is extended to n times the original time. The extended casting time, with the same casting volume, reduces the flow rate of molten aluminum, further avoiding the generation of aluminum slag due to excessive casting speed.

[0014] 2. By setting a detection mechanism directly above the mold, connecting the pouring jug to the output end of the drive mechanism, and connecting the detection mechanism and the drive mechanism to the controller, the liquid level of the molten aluminum in the mold can be monitored in real time through the detection mechanism, and the detected liquid level information can be transmitted to the controller in a timely manner. When the flow rate of the molten aluminum in the boat-shaped chute changes, this change will be directly reflected in the liquid level of the molten aluminum in the mold. The controller controls the movement of the drive mechanism according to the received information, and can accurately adjust the height of the spout to ensure that the thickness of the produced aluminum ingot is uniform, thereby avoiding the occurrence of scrap ingots due to fluctuations in the flow rate of molten aluminum.

[0015] Through the above-mentioned design, this utility model effectively solves the technical problems in the prior art where the distribution device is easily affected by fluctuations in the flow rate of molten aluminum, resulting in waste ingots and generating a large amount of aluminum dross during the flow of molten aluminum.

[0016] Furthermore, the flow hole is connected to the pouring pot via a heat-resistant hose.

[0017] Furthermore, a cap is fixedly installed on the top of the pouring vessel to prevent the molten aluminum from coming into contact with oxygen inside the vessel.

[0018] Furthermore, the top surface of the cap has a vertically extending connecting plate, and the output end of the drive mechanism is connected to the connecting plate to realize the connection between the drive mechanism and the pouring pot.

[0019] Furthermore, the longitudinal section of the nozzle is a trapezoid that is wider at the top and narrower at the bottom.

[0020] Furthermore, there are multiple pouring jugs arranged side by side and all connected to the drive mechanism. The center distance between two adjacent pouring jugs is the same as the center distance between two adjacent molds.

[0021] Furthermore, the pouring vessel is a ceramic pouring vessel or a graphite pouring vessel.

[0022] Furthermore, the driving mechanism is a robot or a servo mechanism.

[0023] Furthermore, the testing mechanism is a laser testing mechanism.

[0024] Furthermore, the flow orifice is equipped with a plug. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] It should be noted that the main concept of the low-slag quantitative casting device provided by this utility model is as follows: by connecting the flow hole of the boat-shaped chute to a casting vessel with multiple spouts at the bottom, molten aluminum can be injected into a single mold simultaneously through multiple spouts during casting. This reduces the casting speed of a single spout while maintaining the overall casting speed, and avoids the generation of aluminum slag due to excessively fast casting speed of a single spout. Furthermore, multiple casting vessels can be used in parallel to simultaneously cast multiple molds, thereby extending the casting time of a single mold while keeping the total casting time of multiple molds constant, thus reducing aluminum slag. The process involves setting up a detection mechanism directly above the mold to monitor the liquid level of the molten aluminum in real time. By connecting the pouring jug to the output of the drive mechanism and connecting both the detection mechanism and the drive mechanism to the controller, the flow rate change of the molten aluminum in the boat-shaped chute during casting is directly reflected by the liquid level of the molten aluminum in the mold. The detection mechanism transmits the detected liquid level information to the controller in a timely manner, and the controller controls the drive mechanism to move according to the received information, thereby precisely adjusting the height of the spout. This ensures that the produced aluminum ingots have uniform thickness and improves the production quality of the aluminum ingots.

[0033] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0034] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0035] Example 1 of the low-slag quantitative casting device provided by this utility model:

[0036] like Figures 1 to 3As shown, the low-slag quantitative casting device includes a pouring jug 1, a drive mechanism, a detection mechanism, and a controller. The pouring jug 1 is connected to the flow hole of the boat-shaped chute 2. The output end of the drive mechanism is connected to the pouring jug 1 to drive the pouring jug 1 to move. The detection mechanism is located directly above the mold 9 to detect the liquid level of the aluminum liquid in the mold 9. Both the detection mechanism and the drive mechanism are connected to the controller to transmit the detected liquid level information to the controller. The controller then controls the drive mechanism to move based on the received information, thereby driving the pouring jug 1 to move.

[0037] Regarding the structural composition of the pouring vessel 1 and its connection with the boat-shaped chute 2 and the drive mechanism: The pouring vessel 1 is made of a non-stick aluminum and high-temperature resistant material, such as a ceramic or graphite pouring vessel 1. There is only one pouring vessel 1. The bottom of the pouring vessel 1 has two spouts 3, and the top is fixedly fitted with a cover 5. The cover 5 is used to prevent the molten aluminum from coming into contact with oxygen inside the pouring vessel 1. The aluminum inlet of the pouring vessel 1 is connected to the flow hole of the boat-shaped chute 2 through a heat-resistant flexible hose 4. The top of the cover 5 has a vertically extending connecting plate 6, and the output end of the drive mechanism is connected to the connecting plate 6.

[0038] Among them, the longitudinal section of the spout 3 is a trapezoid with a wider top and a narrower bottom, and the cap 5 is connected to the pouring pot 1 by bolts.

[0039] It should be noted that the detection mechanism is a laser detection mechanism, the drive mechanism is robot 7, the flow hole of the boat-shaped chute 2 is equipped with a plug 8, the plug 8 can be connected to a cylinder or servo mechanism to control its insertion or removal in the flow hole, or the plug 8 can be manually controlled to insert or remove in the flow hole, and the number of spouts 3 at the bottom of the pouring jug 1 can be more than two.

[0040] In addition, it should be noted that the bottom of the right end of the boat-shaped chute 2 is connected to the output end of the cylinder 11 so that when the flow rate of the molten aluminum is large, the output end of the cylinder 11 is extended to tilt the boat-shaped chute 2, and the molten aluminum stored in the boat-shaped chute 2 flows into the residual aluminum box 10, thereby ensuring the safety of personnel and equipment; the controller is also connected to the horizontal casting machine and the alarm mechanism.

[0041] The working principle of the low-slag quantitative casting device provided by this utility model is as follows:

[0042] Before pouring the molten aluminum, the flow hole in the boat-shaped chute 2 is blocked by the plug 8. After the molten aluminum in the boat-shaped chute 2 reaches the target height, the plug 8 is opened. At this time, the robot 7 controls the pouring jug 1 to be at the highest point to prevent the molten aluminum from flowing into the mold 9.

[0043] After casting begins, the detection mechanism monitors the liquid level of the molten aluminum in the mold 9 in real time and transmits the detected information to the controller. The controller controls the robot 7 to move, causing the pouring jug 1 to fall into the mold 9. Subsequently, the controller controls the movement speed and position of the robot 7 according to the movement speed and position of the mold 9, so that the movement speed of the pouring jug 1 matches the movement speed of the mold 9. The output end of the robot 7 is slowly raised according to the rising speed of the liquid level of the molten aluminum in the mold 9, so as to slowly raise the height of the pouring jug 1. When the liquid level of the molten aluminum in the mold 9 reaches the design value, the controller controls the robot 7 to raise the pouring jug 1 upward, so that the height of the pouring jug 1 is higher than the liquid level of the molten aluminum in the boat-shaped chute 2. The molten aluminum stops flowing into the pouring jug 1, and one casting process is completed.

[0044] By repeating the above process, the aluminum ingot casting work can be continued.

[0045] In addition, when the flow rate of molten aluminum in the boat-shaped chute 2 is small, the controller controls the horizontal casting machine to reduce its speed to extend the casting time, thereby ensuring the amount of casting in the mold 9. When the flow rate of molten aluminum in the boat-shaped chute 2 is large, the controller controls the horizontal casting machine to increase its speed to ensure the amount of casting in the mold 9. If the speed of the horizontal casting machine is increased to the maximum and still cannot meet the casting requirements, the controller controls the alarm mechanism to sound an alarm to remind personnel to control the furnace and adjust the flow rate as soon as possible. In an emergency, the controller controls the robot 7 to raise the pouring jug 1 and at the same time, starts the cylinder 11 to extend its output end and tilt the boat-shaped chute 2. The molten aluminum stored in the boat-shaped chute 2 flows into the residual aluminum box 10, thereby ensuring the safety of personnel and equipment.

[0046] Example 2 of the low-slag quantitative casting device provided by this utility model:

[0047] Its main difference from Example 1 is:

[0048] In Example 1, the number of pouring jugs is one.

[0049] In this embodiment, there are multiple pouring jugs arranged side by side, and the center distance between two adjacent pouring jugs is consistent with the center distance between two adjacent molds. When the liquid level in the two molds is inconsistent, the pouring jugs are tilted by a robot to make the final liquid level in the two molds consistent.

[0050] In this case, assuming that the casting time of a single mold in the prior art is 3 seconds, then the total casting time of two molds is 6 seconds. If the low slag quantitative casting device provided by this utility model is used for casting, two molds can be cast simultaneously, with each mold having a casting time of 6 seconds. The total casting time of the two molds remains 6 seconds, the total casting time remains unchanged, and the casting volume in each mold also remains unchanged. The flow rate of the aluminum liquid is greatly reduced, which can effectively avoid the generation of aluminum slag during the casting process.

[0051] Example 3 of the low-slag quantitative casting device provided by this utility model:

[0052] Its main difference from Example 1 is:

[0053] In Example 1, the driving mechanism is a robot.

[0054] In this embodiment, the driving mechanism is a servo mechanism.
