[0024] See Figure 1 、 Figure 3 and Figure 4As shown, the present application proposes a hollow interlayer cooling mold for casting non-ferrous metal ingots, comprising: a casting panel 1; a forming cavity 3, the forming cavity 3 is arranged on the casting panel 1; a jacket 6, the jacket 6 is arranged at the bottom of the casting panel 1, and the jacket 6 and the casting panel 1 are enclosed to form a hollow interlayer; a cooling pipe mouth 7, the side surface and the bottom surface of the jacket 6 are both provided with cooling pipe mouths 7, and the cooling pipe mouth 7 is connected to the hollow interlayer; a spray structure, the spray structure is arranged in the cooling pipe mouth 7; and a discharge outlet, the discharge outlet is arranged at the bottom of the jacket 6.

[0025] The casting panel 1 and the jacket 6 constitute the structural basis of the hollow interlayer cooling mold for casting non-ferrous metal ingots. Other structures on the hollow interlayer cooling mold for casting non-ferrous metal ingots are directly or indirectly connected to the casting panel 1 or the jacket 6. The forming cavity 3 on the casting panel 1 is used to contain the metal liquid, and the metal liquid solidifies in the forming cavity 3 to form the non-ferrous metal ingot. Preferably, a preheating structure is also included. The preheating structure can be heated by electricity or other heating methods. Since the preheating structure is a mature existing technology, no specific limitation is imposed on the preheating structure here.

[0026] Among them, the cooling nozzle 7 and the spray structure constitute the core structure of the hollow interlayer cooling mold for casting non-ferrous metal ingots. High-pressure cooling liquid is discharged into the cooling nozzle 7. The spray structure atomizes the cooling liquid and then evenly sprays it to the outside of the forming cavity 3, thereby cooling the metal liquid in the forming cavity 3. Since the cooling liquid with a constant temperature can be continuously sprayed to the outside of the forming cavity 3, the metal liquid in the forming cavity 3 is evenly cooled, thereby improving the quality of the final formed non-ferrous metal ingot. In addition, the spray structure has a high utilization rate of the cooling liquid, which is conducive to reducing the amount of cooling liquid used. The cooling liquid that has fully absorbed the heat of the metal liquid flows into the discharge port under the action of gravity and is discharged through the discharge port.

[0027] In this embodiment, the cooling liquid can be any one of cooling water or cooling oil, and also includes a high-pressure pump, a cooling liquid source, a heat exchanger and a reflux pump. The high-pressure pump is used to provide high pressure for the cooling liquid, which is conducive to the atomization of the cooling liquid. After the cooling liquid is discharged through the discharge port, it is cooled by heat exchange through the heat exchanger, so that the temperature of the cooling liquid returns to the preset temperature, and then under the drive of the reflux pump, it flows back to the cooling liquid source to complete the circulation of the cooling liquid.

[0028] Among them, the shape of the molding cavity 3 is roughly a rectangular parallelepiped, and the jacket 6 is also roughly a rectangular parallelepiped. Cooling nozzles 7 are provided on the four side surfaces and one bottom surface of the jacket 6, and two or more cooling nozzles 7 are provided on the two side surfaces parallel to the length direction of the jacket 6, so that the spray range can fully cover the molding cavity 3, so that all sides of the molding cavity 3 can be evenly cooled.

[0029] Specifically, in the process of casting non-ferrous metal ingots, it is necessary to preheat the casting panel 1 and the jacket 6, and then pour the molten metal into the forming cavity 3. During the cooling and forming process of the molten metal in the forming cavity 3, the high-pressure cooling liquid is discharged into the cooling pipe mouth 7, and is atomized through the spray structure, and finally sprayed to the outside of the forming cavity 3, thereby uniformly cooling the molten metal in the forming cavity 3 and improving the quality of the final formed non-ferrous metal ingot. In addition, the spray structure has a high utilization rate of the cooling liquid, which is conducive to reducing the amount of cooling liquid used. The cooling liquid that has fully absorbed the heat of the molten metal flows into the discharge port under the action of gravity and is discharged through the discharge port.

[0030] Among them, the material of the casting panel 1 is a graphite mold, which has excellent high temperature resistance, which is beneficial for the casting panel 1 to withstand the high temperature brought by the metal liquid, ensuring that the graphite mold will not be damaged under the action of high temperature. The material of the jacket 6 is a stainless steel mold, which has excellent mechanical properties and corrosion resistance, which is beneficial to improving the service life of the jacket 6.

[0031] See Figure 3 and Figure 5As shown, in some embodiments, it also includes: a mold wall 9, the mold wall 9 encloses a forming mold cavity 3, and the mold wall 9 is integrally formed with the casting panel 1; the forming mold cavity 3 is in the shape of a rectangular parallelepiped with an open top, and the mold wall 9 includes four side mold walls 9 and one bottom mold wall 9. The forming mold cavity 3 is provided with a draft angle, that is, the inner side of the side mold wall 9 is inclined. In order to ensure that the thickness of the side mold wall 9 is uniform, the outer side of the side mold wall 9 is also set to be inclined and parallel to the inner side surface of the mold wall 9. The mold wall 9 with uniform thickness is conducive to improving the uniformity of the cooling effect of the metal liquid. Isolation protrusions, the isolation protrusions are arranged at intervals on the outer side of the mold wall 9, and the isolation protrusions include a first arc portion 21, a vertical portion 22, a horizontal portion 23 and a second arc portion 24. The isolation protrusion is in the shape of a rectangular ring and is arranged on the outside of the side mold wall 9. The isolation protrusion is integrally formed with the side mold wall 9. The cross-section of the isolation protrusion includes a first arc-shaped portion 21, a vertical portion 22, a horizontal portion 23 and a second arc-shaped portion 24. The structural design of the first arc-shaped portion 21, the vertical portion 22, the horizontal portion 23 and the second arc-shaped portion 24 on the isolation protrusion is conducive to increasing the contact area between the mold wall 9 and the atomized cooling liquid, thereby enhancing the cooling effect of the cooling liquid on the mold wall 9. After the atomized cooling liquid is sprayed onto the outer surface of the mold wall 9, it will flow downward along the outer surface of the mold wall 9 under the action of gravity. The cooling liquid flowing downward can easily cause uneven cooling of the mold wall 9. When the depth of the cooling liquid flowing downward is large, it will also block the cooling of the side mold wall 9 by the atomized cooling liquid, further affecting the uniformity of the cooling effect. Under the guidance and drainage of the first arc-shaped portion 21 of the isolation protrusion, the cooling liquid will flow to the dripping area formed by the vertical portion 22 and the horizontal portion 23, so that the cooling liquid drips directly and is discharged from the discharge port, preventing the cooling liquid from flowing downward along the outer wall of the side mold wall 9, affecting the uniformity of the cooling effect on the mold wall 9, and preventing the depth of the cooling liquid flowing downward from being too large. Due to the inclined setting of the side mold wall 9, the position of the vertical portion 22 in the isolation protrusion gradually approaches the molding cavity 3 along the length of the side mold wall 9. In other words, the cooling liquid dripping from different dripping areas will not affect each other.

[0032] In this embodiment, the setting density of the isolation protrusions gradually increases in the downward direction along the length of the side mold wall 9, that is, the direction of the cooling liquid flow. Since the side mold wall 9 is set at an angle, the cooling liquid spray density on the side of the side mold wall 9 close to the casting panel 1 is high, while the cooling liquid spray density on the side close to the bottom wall is low. Based on this, the setting density of the isolation protrusions on the side with high cooling liquid spray density is small, while the setting density of the isolation protrusions on the side with low cooling liquid spray density is high, further improving the uniformity of the cooling effect on the mold wall 9.

[0033] The horizontal portion 23 is relatively short to avoid a large spray dead angle.

[0034] See Figure 3 and Figure 4 As shown, in some embodiments, the spray structure includes: a mounting rod 20, the mounting rod 20 is arranged in the cooling nozzle 7; the mounting rod 20 is provided with an external thread, an atomizing head 14, the atomizing head 14 is screwed to the mounting rod 20, and the atomizing head 14 is provided with an arc-shaped guide surface 15; the atomizing head 14 is screwed to the mounting rod 20. Since the atomizing head 14 is screwed to the mounting rod 20, the disassembly and maintenance of the atomizing head 14 are relatively convenient. Due to the setting of the atomizing head 14, the area of ​​the flow channel is reduced. At this time, the high-pressure cooling liquid flow rate is further increased, and when the cooling liquid is ejected from the cooling nozzle 7, the cooling liquid is also subjected to shear force and impact force during the flow process, and eventually forms tiny particles. These tiny particles can form a uniform mist to achieve the injection and atomization of the cooling liquid, and a locking nut 17, the locking nut 17 is screwed to the mounting rod 20 and abuts the atomizing head 14. The locking nut 17 is used to lock the position of the atomizing head 14 by friction.

[0035] In this embodiment, several connecting plates 13 are spaced apart on the outer circumference of the mounting rod 20. One side of the connecting plate 13 is welded to the mounting rod 20, and the other side is welded to the inner wall of the cooling nozzle 7. Preferably, there are three connecting plates 13, with the angle between two adjacent connecting plates 13 being 120°. A gasket 16 is also provided between the locking nut 17 and the atomizing head 14.

[0036] The jacket 6 further includes an arc-shaped reflection area 8 disposed at the inner bottom of the jacket 6. The arc-shaped reflection area 8 is used to reflect the cooling liquid spray. After being reflected by the arc-shaped reflection area 8, the cooling liquid spray bounces back onto the mold wall 9, thereby improving the utilization rate of the cooling liquid spray.

[0037] See Figure 3 and Figure 4 As shown, in some embodiments, the spray structure further includes a plurality of uniform flow holes, which are arranged on the atomizing head 14. The uniform flow holes evenly arranged on the atomizing head 14 are conducive to increasing the density of the cooling liquid spray at the atomizing head 14, making the density of the cooling liquid spray tend to be uniform.

[0038] See Figure 2 and Figure 3 As shown, in some embodiments, the flow-distributing orifice includes: a converging flow channel 19, whose cross-sectional area gradually decreases; in the converging flow channel 19, the high-pressure cooling liquid is further accelerated; and a flaring flow channel 18, which connects to the converging flow channel 19 and whose cross-sectional area gradually increases. The cooling liquid accelerated by the converging flow channel 19 is ejected from the flaring flow channel 18, which has a short length and can restrict the direction of the cooling liquid spray.

[0039] In this embodiment, a transition channel is further provided between the gradually contracting channel 19 and the reducing channel to prevent the high-pressure cooling liquid from directly impacting the atomizing head 14 , thereby increasing the service life of the atomizing head 14 .

[0040] See Figure 1 and Figure 2 As shown, in some embodiments, it also includes: a first connection hole, the first connection hole is provided on both the casting panel 1 and the jacket 6; the casting panel 1 and the jacket 6 are connected by a fastener and the first connection hole 2, the first connection hole 2 on the jacket 6 is provided with an internal thread, and the bolt is screwed to the first connection hole 2 on the jacket 6. The first connection hole 2 on the casting panel 1 is not provided with an internal thread, but the size of the first connection hole 2 on the casting panel 1 is adapted to the outer diameter of the bolt, the first connection hole 2 on the casting panel 1 passes through the bolt, and the casting panel 1 is attached to the jacket 6, and then the casting panel 1 is locked to the jacket 6 by tightening the nut and the gasket 16 to complete the installation of the casting panel 1. A pipe nozzle, a pipe nozzle is screwed into part of the first connection hole, and the first connection holes 2 on the casting panel 1 and the jacket 6 are screwed to the pipe nozzle, and the pipe nozzle can also serve to connect the casting panel 1 and the jacket 6; an air intake check valve, one end of the air intake check valve is screwed to the pipe nozzle; an air extraction box 25, the other end of the air intake check valve is screwed to the air extraction box. High-temperature resistant sealing gaskets are provided between the air inlet one-way valve and the pipe mouth, and between the air inlet one-way valve and the vacuum box 25, to improve their sealing performance. During the spray cooling process, the spray is vaporized by heat, resulting in a large amount of water vapor in the hollow interlayer. A large amount of water vapor will affect the cooling efficiency, and a large amount of water vapor is difficult to remove in time, which will cause the pressure in the hollow interlayer to gradually increase, affecting the forming of the metal ingot and not conducive to the spraying of the cooling liquid spray. The vacuum box is used to extract the water vapor in the hollow interlayer to improve the cooling efficiency, and the vacuum box will put the hollow interlayer in a state of slight negative pressure, which is conducive to the rapid spraying of the spray into the hollow interlayer. Preferably, a support is also provided between the bottom of the vacuum box 25 and the casting panel 1 to support the vacuum box 25.

[0041] See Figure 1 、 Figure 2 and Figure 6As shown, in some embodiments, it also includes: an end plate 27, which is arranged on the air extraction box 25; connecting holes are arranged at intervals on the end plate 27, and the end plate 27 is installed on the air extraction box 25 through screws and the connecting holes. An opening is provided at one end of the air extraction box 25, and the end plate 27 is used to seal the opening of the air extraction box 25.

In the process of the vacuum drive 26 driving the main shaft 32 to rotate, the cam 30 drives the connecting rod 31 to rotate, thereby driving the piston 33 to reciprocate in the vacuum box 25. When the piston 33 approaches the cam 30, the vacuum box 25 extracts the water vapor in the hollow interlayer through the air inlet one-way valve. When the piston 33 moves away from the cam 30, the vacuum box 25 discharges the water vapor through the one-way exhaust port 28. The one-way exhaust port 28 is provided with an exhaust port 29, which can be connected to an external component to recover the heat in the water vapor. The water vapor in the hollow interlayer can be extracted through the above steps, and the vacuum drive 26, the main shaft 32 and the cam 30 are not in direct contact with the water vapor, which is beneficial to improving the service life of the power structure. Preferably, the piston 33 is made of stainless steel. The number of vacuum boxes 25 can be selected according to actual needs.

The push rod 11 is driven by an external actuator to push the demolding member 10, thereby demolding the metal ingot. The external actuator can be a hydraulic cylinder, etc., and is not specifically limited here.

[0043] See Figure 1 and Figure 2As shown, in some embodiments, the jacket 6 is further comprised of a mounting base 4, which is disposed on the jacket 6; and a second connection hole 5, which is disposed on the mounting base 4.
