Description

Technical Field

[0001] The present invention relates to a method and device for ensuring the quality of molten aluminum, and in particular to a method and device for ensuring the quality of molten aluminum during the casting process of aluminum ingots. Background Art

[0002] Cast aluminum alloys are aluminum products produced through the casting process, a technique in which molten metal is poured into a casting cavity designed to match the desired part shape, and then cooled and solidified to produce a part or blank. Currently, the primary method for forming aluminum ingots is to inject the molten aluminum alloy into a mold and allow it to cool and form. Die-casting aluminum ingots essentially involves filling the die-casting cavity with liquid or semi-liquid metal at a high speed under high pressure, where it is formed and solidified under pressure to produce the casting. Due to the high speed at which the liquid metal fills the mold cavity and the unstable flow pattern, conventional distribution devices are used during die-casting. Since the molten aluminum needs to flow into the mold, a stable input is required. Failure to constantly control the molten aluminum can easily lead to overflow after the mold is filled with molten aluminum. Furthermore, the lack of exhaust can hinder the die-casting process.

[0003] In view of this, it is necessary to design a device to ensure the quality of molten aluminum during the aluminum ingot casting process. Summary of the Invention

[0004] In order to solve the deficiencies of the above technologies, the present invention provides a method and device for ensuring the quality of molten aluminum during the aluminum ingot casting process.

[0008] The auxiliary exhaust mechanism is located above the drain pan and includes:

[0009] A sliding plate, the middle of which is connected to a circular carrier plate, and a plurality of exhaust heads are arranged at intervals below the circular carrier plate;

[0010] The driving mechanism connected to the sliding plate is used to drive the sliding plate to move up and down.

[0011] Preferably, the drain pan is provided with a plurality of drain holes connected to the drain pipe, and the drain holes correspond to the exhaust heads one by one.

The two pulleys are connected by a belt, and the free end of one of the threaded rods is connected to the output shaft of the motor.

[0015] Preferably, the sliding plate is placed on the threaded rod and is threadably connected to the threaded rod.

[0016] Preferably, sliding grooves are symmetrically provided on the inner wall of the accommodating cylinder, and sliding blocks are symmetrically provided at both ends of the sliding plate. The sliding blocks are embedded in the sliding grooves and can slide up and down along the sliding grooves.

[0017] Preferably, a fixing seat is provided below the accommodating cylinder, and support columns are respectively installed at the bottom corners of the fixing seat.

[0018] Preferably, a through hole with a diameter smaller than that of the accommodating cylinder is formed at the center of the fixing seat, and the accommodating cylinder is placed above the through hole and the center lines of the two coincide.

[0019] Preferably, the method specifically comprises:

[0020] The aluminum liquid enters the holding cylinder through the liquid inlet pipe. At this time, the valve on the discharge pipe is closed. When the holding cylinder is filled with aluminum liquid, the valve is opened to allow the aluminum liquid to be discharged through the discharge pipe, ensuring uniform distribution of the aluminum liquid.

[0021] After the aluminum liquid is discharged, the motor is started, and the motor drives the threaded rod connected to it to rotate. The rotation of the threaded rod drives the pulley on it to rotate, and further drives another threaded rod to rotate through the belt.

By utilizing the auxiliary exhaust mechanism to control the quality of the molten aluminum, the casting effect of the aluminum ingot is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] Figure 1 The device for ensuring the quality of molten aluminum during the casting process of aluminum ingots shown includes:

[0030] The accommodating cylinder 1 is used to hold the aluminum liquid, and the accommodating cylinder 1 is connected with a liquid inlet pipe 11. By arranging the liquid inlet pipe to be connected with the aluminum liquid delivery pipe, the aluminum liquid can be delivered into the accommodating cylinder, which is convenient for the subsequent distribution of the aluminum liquid.

[0031] A drain pan 2 is located at the bottom of the accommodating cylinder. A plurality of drain pipes 22 are provided at intervals on the bottom surface of the drain pan 2. Valves are installed on the drain pipes 22.

[0032] By setting up the discharge pipe, the aluminum liquid can be evenly distributed. Since the size, diameter and length of each discharge pipe are the same, when the aluminum liquid enters the containing cylinder, the aluminum liquid can be evenly distributed through the discharge pipe.

[0033] The auxiliary exhaust mechanism 3 is located above the drain pan 2, such as Figure 2As shown, the auxiliary exhaust mechanism 3 includes: by setting up an auxiliary exhaust mechanism, the residual aluminum liquid or bubbles generated in the discharge pipe are eliminated to ensure that no bubbles are generated when the aluminum liquid enters next time, thereby avoiding bubbles in the subsequent die-cast aluminum ingots and improving the die-casting quality of the aluminum liquid.

[0034] A sliding plate 31, a circular carrier plate 32 is connected to the middle of the sliding plate 31, and a plurality of exhaust heads 33 are arranged at intervals below the circular carrier plate 32;

[0035] By setting a sliding plate, it can slide along the inner wall of the accommodating cylinder to adjust the position of the auxiliary exhaust mechanism, and by setting an exhaust head, the exhaust operation of the exhaust pipe can be performed.

[0036] The driving mechanism connected to the sliding plate 31 is used to drive the sliding plate 31 to move up and down.

[0037] A driving mechanism is provided to drive the sliding plate to slide along the inner wall of the accommodating cylinder, thereby further assisting exhaust.

[0038] Specifically, the drain pan 2 is provided with a plurality of drain holes 21 connected to the drain pipe, and the drain holes 21 correspond to the exhaust heads 33 one by one.

[0039] By opening drainage holes and corresponding the drainage holes to the exhaust heads one by one, the exhaust heads can enter the drainage pipe through the drainage holes, and at the same time, the aluminum liquid enters the mold along the discharge pipe through the drainage holes, so that multiple exhaust heads can enter the discharge pipe at the same time to perform exhaust operations.

[0040] Furthermore, a number of rectangular blocks 34 are arranged at intervals on the bottom surface of the circular carrier plate 32, and a movable rod 35 is vertically inserted in the middle of the rectangular block 34. The movable rod 35 is connected to the pressure plate 36 on one side close to the circular carrier plate, and an exhaust head 33 is provided at the other end. A spring 37 is sleeved between the movable rod 35 and the pressure plate.

[0041] In order to adjust the exhaust head, a pressure plate is provided under the circular carrier plate, which is connected to the end of the movable rod, and the other end of the movable rod passes through the rectangular block and is connected to the exhaust head. At the same time, the rectangular block is fixedly connected to the circular carrier plate through the connecting block. Therefore, in the process of the pressure plate squeezing the movable rod, the movable rod can move up and down along the rectangular block, thereby realizing the adjustment of the position of the exhaust head, so that the exhaust head can enter the drain hole and move up and down along the discharge pipe to complete operations such as eliminating bubbles.

[0042] Preferably, the pressing plate 36 is located below the circular carrier plate 32 , and the center of the pressing plate 36 is connected to the output end of the cylinder 38 , which is located on the circular carrier plate; the top of the rectangular block 34 is fixedly connected to the circular carrier plate through a connecting block 39 .

[0043] By setting a spring between the movable rod and the pressure plate, the movable rod has room to move downward. When the pressure plate moves downward to produce maximum compression on the spring, the movable rod stops moving. At this time, the pressure on the movable rod is withdrawn. Under the action of the spring, the movable rod will automatically reset, and the cylinder will drive the pressure plate to move upward to its initial position.

[0044] As a preference, Figure 3 As shown, the driving mechanism includes two sets of threaded rods 41 arranged in parallel, one end of each set of threaded rods 41 is provided with a limit block 42, and the other end passes through the top of the accommodating cylinder and is connected to the pulley. The two pulleys are connected by a belt 44, and the free end of one of the threaded rods is connected to the output shaft of the motor 43.

[0045] By setting a threaded rod, the sliding plate can be moved up and down, thereby driving the circular carrier plate to move downward as a whole, so that the exhaust operation of the subsequent exhaust head can be realized;

[0046] The specific working process is: start the motor, the motor drives one of the threaded rods to rotate, thereby driving the pulley on it to rotate, and transmission is achieved through the belt between the two pulleys, thereby driving the other threaded rod to rotate synchronously. During the rotation of the threaded rod, the sliding plate is driven up and down.

[0047] In order to facilitate the position adjustment of the sliding plate, the sliding plate 31 is placed on the threaded rod 41 and connected with its thread. Thereby, after the threaded rod rotates, the sliding plate can move along the threaded rod to achieve the adjustment of the position of the auxiliary exhaust mechanism.

[0048] In order to cooperate with the movement of the sliding plate, sliding grooves are symmetrically opened on the inner wall of the accommodating cylinder 1, and sliders are symmetrically provided at both ends of the sliding plate 31. The sliders are embedded in the sliding grooves and can slide up and down along the sliding grooves.

[0049] By providing a sliding groove on the inner wall of the accommodating cylinder, not only can the position of the sliding plate be adjusted, but it can also ensure that the sliding plate can maintain linear movement during the movement process, thereby ensuring the subsequent exhaust effect.

[0050] Preferably, a fixing base 10 is provided below the accommodating cylinder 1, and support columns 12 are respectively installed at the top corners of the bottom of the fixing base 10. A through hole with a diameter smaller than that of the accommodating cylinder is formed in the center of the fixing base 10, and the accommodating cylinder 1 is placed above the through hole and the center lines of the two coincide.

[0051] The accommodating cylinder is supported by providing a fixing seat, and a through hole is opened in the center of the fixing seat so that the accommodating cylinder can be placed on the fixing seat, ensuring that the discharge pipe can be placed normally.

[0052] The method specifically includes:

[0053] The aluminum liquid enters the holding cylinder through the liquid inlet pipe. At this time, the valve on the discharge pipe is closed. When the holding cylinder is filled with aluminum liquid, the valve is opened to allow the aluminum liquid to be discharged through the discharge pipe, ensuring uniform distribution of the aluminum liquid.

[0054] After the aluminum liquid is discharged, the motor is started, and the motor drives the threaded rod connected to it to rotate. The rotation of the threaded rod drives the pulley on it to rotate, and further drives another threaded rod to rotate through the belt. During the rotation of the threaded rod, the sliding plate connected to its thread slides downward along the inner wall of the accommodating cylinder until it slides to the end of the slide groove. At this time, the cylinder is started, and the cylinder drives the pressure plate to move downward. During the downward movement of the pressure plate, external force is applied to the movable rod connected to it, so that the movable rod moves downward along the rectangular block. In this process, the spring is squeezed, and the exhaust head at the end of the movable rod enters the exhaust hole and moves downward along the discharge pipe. Exhaust is achieved in this process, and then the pressure plate is reset by the cylinder, and the sliding plate is reset by the motor to continue the next liquid inlet distribution of aluminum liquid.

[0055] Example 2

[0056] The difference between this embodiment and embodiment 1 is that the driving mechanism used is different. The driving mechanism includes: a cylinder installed on the top of the accommodating tube, there are two cylinders, the output ends of the two cylinders are respectively fixedly connected to the sliding top, and the sliding plate is driven by the cylinder to slide along the inner wall of the accommodating tube to realize the position adjustment of the auxiliary exhaust mechanism.

[0057] The purpose of the present invention is to provide a method and device for ensuring the quality of aluminum liquid during the casting process of aluminum ingots. By pouring aluminum liquid into the inner cavity of a holding box, the aluminum liquid will be discharged from the discharge pipe at the bottom of the holding box and discharged into the mold of the production line below. After the aluminum liquid in the mold is filled, the discharge pipe can be closed by a valve, thereby blocking the discharge pipe and preventing the aluminum liquid in the holding box from flowing out, thereby achieving uniform distribution of the aluminum liquid. At the same time, by providing an auxiliary exhaust mechanism, the liquid or bubbles in the discharge pipe are eliminated through the exhaust head, thereby ensuring the pressing quality of the aluminum ingot.

[0058] The above embodiments are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
