Description

Technical Field

[0001] This invention relates to the field of mold cooling technology, and in particular to a temperature-adjustable cooling device for zinc ingot casting molds. Background Technology

[0002] Zinc ingots are typically formed using molds during the casting process. During this process, the molds need to be cooled promptly to ensure the quality of the solidified zinc. Current technologies often employ a single cooling method, such as simple air cooling or water cooling, to lower the temperature of the mold.

[0003] Air cooling has a simple structure but limited heat exchange capacity, making it difficult to meet the demand for rapid cooling at high temperatures. Water cooling, while having higher heat exchange efficiency, suffers from inflexible temperature regulation and large local temperature differences.

[0004] Furthermore, in actual production, the cooling intensity requirements of the mold vary at different stages, and traditional cooling devices are difficult to control in stages.

[0005] Based on the above, the existing zinc ingot casting mold cooling devices have the problems of a single cooling method and insufficient temperature regulation capacity. It is difficult to flexibly switch or adjust the cooling intensity according to different stages of casting, which makes it difficult to balance cooling efficiency and uniformity, thus affecting the zinc ingot forming quality and production stability.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1 to 7 The first embodiment of the present invention provides a temperature-adjustable zinc ingot casting mold cooling device, which includes an air-cooling component, a water-cooling component and an evaporation component.

[0038] Specifically, it includes mold body 1, which is used to hold molten zinc and form zinc ingots.

[0039] The air-cooled assembly includes a cooling jacket 2 disposed outside the mold body 1, an air vent 23 opened on the side of the cooling jacket 2, and an air guide groove 7 opened on the inner bottom surface of the cooling jacket 2 and connected to the air vent 23. The air guide groove 7 guides the airflow to flow along the bottom surface of the mold body 1 to form a stable convection heat exchange channel.

[0040] The water-cooling assembly includes a water tank 4 located at the bottom of the cooling jacket 2, a water trough 9 located on the top surface of the cooling jacket 2, a return hole 16 and micro channels 25 located between the water trough 9 and the water tank 4, and a water pump 13 located inside the water tank 4 and connected to the micro channels 25 by a pipe. The water tank 4 is used to store coolant and provide a circulation source, the water trough 9 is used to temporarily store or distribute coolant, and the water pump 13 drives the coolant to circulate.

[0041] The evaporation assembly includes a heat spreader 24 arrayed on the inner wall of the air vent 23 and overflow holes 15 opened on the upper and lower inner walls of the air vent 23 and connected to the water tank 9 and the water container 4 respectively. The heat spreader 24 achieves uniform heat distribution, and the overflow holes 15 achieve liquid overflow, thereby providing a stable liquid source for evaporation.

[0042] In use, in the first stage, the air-cooling component is used alone. First, the external exhaust fan connected to the external pipe 3 draws the inside of the air duct 6 into negative pressure. The negative pressure of the air duct 6 is diffused to the air outlet 23 through the air guide groove 7, so that the outside air enters through the air outlet 23 and flows to the air duct 6 along the air guide groove 7. The air guide groove 7 is located on the bottom surface of the mold body 1, so the air flows quickly on the bottom surface of the mold body 1, thereby carrying heat to complete the cooling.

[0043] Alternatively, the water cooling component can be used alone. Open the cover plate 10 to add water to the water tank 9. The water flows along the return hole 16 to the water tank 4. The water pump 13 starts and pumps the water in the water tank 4 to the micro channel 25 through the connecting pipe 14. Under the action of water pressure, the water flows to the water tank 9, thus completing the water circulation. The heat conduction plate 8 is in close contact with the surface of the mold body 1 to complete the heat exchange and achieve the cooling effect. When the water flows along the micro channel 25, it carries away the heat of the heat conduction plate 8, so that the heat conduction plate 8 can continuously cool down the mold body 1. When the water flows along the return hole 16, it dissipates heat through the heat dissipation plate 24, which is beneficial to the temperature control of the water and continuous cooling.

[0044] In the second stage, the water-cooling component and the air-cooling component are activated simultaneously to work together. When the outside air enters through the air vent 23, it first blows over the heat spreader 24. The air flow accelerates the heat dissipation of the water flowing inside the heat spreader 24. Then, the air blows over the surface of the heat conduction plate 8, accelerating the removal of heat from the heat conduction plate 8, so that the heat conduction plate 8 can continuously cool down the mold body 1 and improve the cooling efficiency.

[0045] In the third stage, in conjunction with the evaporation assembly, the screw 17 is first rotated relative to the cover plate 10 by the knob 11. Then, the horizontal plate 18 drives the vertical rod 19 to rise along the positioning cylinder 20, driving the plunger 21 to no longer block the overflow hole 15. The water inside the water tank 9 flows downward through the overflow hole 15 with gravity. The guide rod 22 guides the water flowing down from the overflow hole 15 to the surface of the heat spreader 24. When the air passes through the air vent 23, it accelerates the evaporation of the water on the surface of the heat spreader 24. The evaporation of the liquid absorbs a large amount of heat, so that the air passing through the heat spreader 24 is lower than the room temperature. The cold air is beneficial to the cooling of the mold body 1 and improves the performance of the air-cooling assembly. At the same time, the heat spreader 24 absorbs heat from the liquid evaporation, which is beneficial to the cooling of the water flow inside it, ensuring the heat conduction capacity of the water flow and thus improving the performance of the water-cooling assembly.

[0046] In summary, this embodiment achieves multi-level control of the mold cooling process through the coordinated operation of air-cooled components, water-cooled components, and evaporation components, thereby improving the overall cooling performance. The air-cooled components form directional airflow to achieve basic convection cooling, the water-cooled components establish a circulating liquid cooling path to improve heat conduction and heat transfer efficiency, and the evaporation components introduce phase change heat absorption to further reduce local temperature. At the same time, each component can work individually or in combination according to the stage of use, making the cooling intensity adjustable.

[0047] Example 2

[0048] Reference Figures 1 to 7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an air-cooled component and a water-cooled component for a temperature-adjustable zinc ingot casting mold cooling device.

[0049] Specifically, the inner wall of the cooling jacket 2 is provided with a heat-conducting plate 8 that is in contact with the surface of the mold body 1. There is a gap between the heat-conducting plate 8 and the air outlet 23. The air guide groove 7 is connected to the gap. The gap of the heat-conducting plate 8 is used to form an airflow channel to improve the convective heat transfer effect.

[0050] A mounting frame 12 is provided on the outer side of the cooling jacket 2 and on the outer periphery of the air outlet 23. A filter screen 5 is detachably covered on the outer port of the mounting frame 12. The filter screen 5 is used to block external impurities from entering the air duct, thereby avoiding clogging of the air guide structure or affecting the stability of the airflow.

[0051] Multiple sets of air guide ducts 7 are provided and spaced apart. The cooling jacket 2 is equipped with an air duct 6 that is connected to the air guide duct 7. The cooling jacket 2 is equipped with an external pipe 3 that is connected to the air duct 6. Multiple sets of air guide ducts 7 can form a multi-path airflow distribution structure. The air duct 6 is used to collect or distribute airflow, and the external pipe 3 is used to connect to external air source equipment, thereby realizing active ventilation.

[0052] The micro-channel 25 penetrates the heat-conducting plate 8. A connecting pipe 14 is provided between the output end of the water pump 13 and the bottom port of the micro-channel 25. A cover plate 10 is provided to cover the top opening of the water tank 9. The micro-channel 25 penetrates the heat-conducting plate 8 so that the coolant can directly act on the heat source area. The connecting pipe 14 is used to ensure stable water flow. The cover plate 10 is used to seal the water tank 9 to reduce evaporation loss and prevent external pollution from entering.

[0053] Furthermore, the heat spreader 24 is provided with multiple sets of spaced distribution, and the reflux holes 16 penetrate the heat spreader 24. The reflux holes 16 are in a continuous "S" shape inside the heat spreader 24. Multiple sets of heat spreaders 24 can expand the evaporation heat exchange area. The "S"-shaped reflux holes 16 are used to extend the liquid flow path, thereby increasing the contact time between the liquid and the heat spreader 24 to improve the heat exchange efficiency.

[0054] The rest of the structure is the same as in Example 1.

[0055] During use, negative pressure is introduced into the air duct 6 through the external pipe 3 and distributed to each air guide slot 7, so that the airflow flows evenly along the gap of the heat exchange plate 24. At the same time, the water pump 13 drives the coolant to enter the micro water channel 25 through the connecting pipe 14 to directly cool the heat conduction plate 8. The coolant flows back through the return hole 16, and part of the coolant evaporates on the surface of the heat exchange plate 24 through the overflow hole 15, thereby realizing the enhanced heat exchange process.

[0056] In summary, this embodiment improves the heat exchange on the mold surface by adding a heat-conducting plate 8 and optimizing the airflow and liquid flow channel structure, while also enhancing reliability through filtration and a closed structure.

[0057] Example 3

[0058] Reference Figures 1 to 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an evaporation component for a temperature-adjustable zinc ingot casting mold cooling device.

[0059] Specifically, a guide rod 22 is provided on the top inner wall of the air vent 23 and between the intervals of the heat spreader 24. The guide rod 22 is located below the port of the overflow hole 15 and there is a gap between the guide rod 22 and the overflow hole 15. The guide rod 22 is used to change the direction of liquid flow so that the liquid can be evenly distributed on the surface of the heat spreader 24.

[0060] The heat spreader 24 has an "H" shaped cross-section. Both the upper and lower ends of the air vent 23 are equipped with baffles 26 located between the gaps in the heat spreader 24. The "H" shaped structure can improve the heat diffusion capacity. The baffles 26 are used to prevent the coolant from flowing out and to concentrate it through the area of ​​the heat spreader 24 to enhance the cooling effect.

[0061] A plug 21 is provided at the upper end of the overflow hole 15. A positioning cylinder 20 is provided on the inner wall of the water tank 9 above the plug 21. A vertical rod 19 is provided at the top of the plug 21, penetrating the positioning cylinder 20. The plug 21 is used to adjust or close the overflow hole 15, and the positioning cylinder 20 is used to guide the vertical rod 19.

[0062] A horizontal plate 18 is provided at the top of the upright 19, and a lead screw 17 is rotatably provided at the top of the horizontal plate 18. The lead screw 17 is threaded through the cover plate 10 and a knob 11 is provided at its end. The lead screw 17 achieves axial displacement by rotation, and the knob 11 is used for manual operation, thereby achieving precise adjustment of the position of the plunger 21.

[0063] The rest of the structure is the same as in Example 2.

[0064] In use, rotating the knob 11 drives the lead screw 17 to rotate, thereby driving the upright rod 19 and the plug 21 to move up and down to adjust the opening degree of the overflow hole 15. When the opening degree is increased, more coolant enters the heat spreader 24 area to participate in evaporative cooling. When the opening degree is decreased, the evaporation rate is reduced, thereby adjusting the cooling intensity. At the same time, the guide rod 22 makes the liquid distribution more uniform.

[0065] In summary, this embodiment achieves precise temperature control of the mold by setting an adjustable overflow control structure, making the evaporation cooling process controllable.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
