[0002] The main equipment for the rapid solidification and casting process of NdFeB permanent magnets consists of three parts: a medium-frequency induction power supply, a vacuum unit, and a vacuum container. The smelting crucible, tundish, rollers, and cooling tank are assembled inside the vacuum container. The preparation process is as follows: the smelted raw material is ejected from the crucible nozzle and poured through the tundish onto rotating cooling copper rollers, thus achieving initial cooling of the cast sheet.

[0003] The strong adhesion between the mold and the ingot makes the traditional rigid demolding method complicated and requires manual assistance, which is time-consuming and labor-intensive, affecting the overall production rhythm. Moreover, the direct pushing by the cylinder can easily cause surface damage and edge cracking of the ingot, resulting in a high scrap rate. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-4 This utility model provides an embodiment of an upgraded ingot casting device for a neodymium iron boron (NdFeB) casting furnace, comprising a support 1, a control motor 2 fixedly connected to the inner wall of the support 1, a turntable frame 3 rotatably connected to the top of the support 1, multiple ingot molds 4 fixedly connected to the inner wall of the turntable frame 3, a first push rod frame 5 slidably connected to the inner wall of the ingot mold 4, a second push rod frame 6 slidably connected to the inner wall of the first push rod frame 5, a first spring 7 provided on the inner wall of the first push rod frame 5, a second spring 8 slidably connected to the outer wall of the second push rod frame 6, an electric push rod 9 and a hydraulic push rod 13 slidably connected to the outer wall of the support 1, a connecting frame 14 fixedly connected to the top of the hydraulic push rod 13, a pressing cover 16 fixedly connected to the bottom of the connecting frame 14, a casting furnace fixedly connected to the outer wall of the support 1, a casting assembly provided on the inner wall of the casting furnace, and a cooling assembly provided on the outer wall of the connecting frame 14.

[0024] Specifically, the support 1 is installed inside the casting furnace, the turntable frame 3 is rotatably connected to the top of the support 1, the control motor 2 is fixedly connected to the inner wall of the support 1 so that its output end is connected to the turntable frame 3, the second push rod frame 6 is slidably connected to the inner wall of the first push rod frame 5, so that the first spring 7 is located between the first push rod frame 5 and the second push rod frame 6, the first push rod frame 5 and the second push rod frame 6 are slidably connected to the inner wall of the ingot mold 4, so that the second spring 8 is located between the second push rod frame 6 and the ingot mold 4; the inner wall of the first spring 7 After the NdFeB castings are cooled, the motor 2 drives the turntable 3 to move the cooled NdFeB castings above the electric push rod 9 through the ingot mold 4. The electric push rod 9 then pushes the second push rod 6 upward, causing the first push rod 5 to push the NdFeB castings upward through the first spring 7 and the second push rod 6, thus detaching the NdFeB castings from the ingot mold 4. During the upward movement of the electric push rod 9, the elasticity of the first spring 7 prevents the first push rod 5 from applying excessive force, which could damage the NdFeB castings during demolding.

[0025] Reference Figure 1 and Figure 4 The cooling assembly includes a water delivery pipe 15, which is fixedly connected to the outer wall of the connecting frame 14. Multiple cooling water pipes 17 are installed on the inner wall of the ingot mold 4. A collection cylinder 18 is fixedly connected to the inner wall of the bracket 1. The water delivery pipe 15 is slidably connected to the top of the multiple cooling water pipes 17. The multiple cooling water pipes 17 are installed on the inner wall of the turntable frame 3. The collection cylinder 18 is installed below the water delivery pipe 15 and the cooling water pipes 17. The bottom end of the collection cylinder 18 is connected to a sewer. One end of the water delivery pipe 15 is fixedly connected to a faucet.

[0026] Specifically, a water delivery pipe 15 is installed on the outer wall of the connecting frame 14, multiple cooling water pipes 17 are installed on the inner wall of the ingot mold 4, and a collection cylinder 18 is installed below the water delivery pipe 15 and is connected to the sewer and fixedly connected to the inner wall of the bracket 1. When the water delivery pipe 15 moves downward through the hydraulic push rod 13 and the connecting frame 14, the water delivery pipe 15 contacts the cooling water pipe 17, allowing cold water from the faucet to enter the multiple cooling water pipes 17 through the water delivery pipe 15 and then flow into the collection cylinder 18 to cool the neodymium iron boron casting in the first spring 7, thus achieving the effect of convenient cooling of the neodymium iron boron casting.

[0027] Reference Figure 1 and Figure 3 The casting assembly includes a tiltable crucible 10, which is installed on the inner wall of the casting furnace. A transfer trough 11 is fixedly connected to the inner wall of the casting furnace. A conveying pipe 12 is fixedly connected to the bottom end of the transfer trough 11. The tiltable crucible 10 is installed above the transfer trough 11, and the conveying pipe 12 is installed above one of the ingot molds 4.

[0028] Specifically, the tiltable crucible 10 and the transfer trough 11 are not suspended in the air, but are installed inside the casting furnace. Due to the large size of the complete structural diagram, the structural diagram of the casting furnace is omitted. They are fixedly connected to the bottom of the transfer trough 11 through the conveying pipe 12. The transfer trough 11 is installed on the inner wall of the casting furnace, and the tiltable crucible 10 is installed on the inner wall of the casting furnace. The transfer trough 11 and the conveying pipe 12 are installed between the tiltable crucible 10 and the ingot mold 4. By rotating the tiltable crucible 10, the casting liquid is poured into the transfer trough 11 and flows into the ingot mold 4 through the conveying pipe 12, thereby achieving the effect of casting NdFeB ingots.

[0029] Reference Figure 3 and Figure 4The turntable frame 3 is fixedly connected to the output end of the control motor 2. The pressing cover 16 is slidably connected to the top of the ingot mold 4. The electric push rod 9 is slidably connected to the bottom end of the second push rod frame 6. The second push rod frame 6 is slidably connected to the inner wall of the ingot mold 4. The first spring 7 is set at the top of the second push rod frame 6. The second spring 8 is set at the inner wall of the ingot mold 4. The second spring 8 is slidably connected to the outer wall of the first push rod frame 5.

[0030] Specifically, the second spring 8 causes the second push rod 6 to move the first push rod 5 downward, so that the first push rod 5 is in close contact with the ingot mold 4, preventing loosening and gaps between the first push rod 5 and the ingot mold 4. The first spring 7 between the first push rod 5 and the second push rod 6 can reduce the upward thrust of the electric push rod 9 through its elasticity, thus preventing damage to the NdFeB casting sheet during demolding.

[0031] Working principle: The neodymium iron boron raw material in the tilting crucible 10 is heated and melted in the casting furnace. Then, the tilting crucible 10 is rotated to pour the neodymium iron boron casting liquid into the transfer tank 11. The casting liquid is then poured into the ingot mold 4 below the transfer pipe 12 through the delivery pipe 12. The control motor 2 is started, which causes the turntable frame 3 to rotate the casting liquid through the ingot mold 4 to the bottom of the connecting frame 14. The hydraulic push rod 13 then moves the connecting frame 14 and the pressing cover 16 downwards, so that 6 contacts the ingot mold 4. The casting liquid is cooled by the cooling assembly, and then the hydraulic push rod 13 drives the pressing cover 16 to move upward through the connecting frame 14, so that the pressing cover 16 is separated from the ingot mold 4. Then the control motor 2 is started, so that the NdFeB casting sheet rotates above the electric push rod 9, and the electric push rod 9 pushes the second push rod frame 6 upward, so that the second push rod frame 6 is driven upward by the first spring 7 and the first push rod frame 5, so that the NdFeB casting sheet is separated from the ingot mold 4, thereby avoiding damage to the NdFeB casting sheet during demolding.

[0032] When the pressing cover 16 contacts the ingot mold 4, the water supply pipe 15 contacts the top of multiple cooling water pipes 17 through the connecting bracket 14, allowing cold water from the tap to pass through the water supply pipe 15 into the cooling water pipes 17, thus cooling the ingot mold 4. The cold water then flows from the outlet of the cooling water pipes 17 into the collection cylinder 18, achieving the effect of convenient cooling of the NdFeB casting sheet.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
