[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is for reference. Figure 1 A cooling device 1 for a casting machine according to an embodiment of the present invention is described.

[0026] According to the first aspect of the present invention, a cooling device 1 for a casting machine, such as... Figure 1 As shown, the cooling device 1 for the casting machine may include: an inlet pipe 10, an outlet pipe 20, and a plurality of spray pipes 30. Each spray pipe 30 is connected to the inlet pipe 10 and the outlet pipe 20, and each spray pipe 30 has a plurality of spray holes 31. The plurality of spray holes 31 of each spray pipe 30 are arranged sequentially along the length direction of the corresponding spray pipe 30, and at least two of the plurality of spray holes 31 of each spray pipe 30 have different diameters.

[0027] It should be noted that the existing cooling devices used for casting machines have poor cooling effects, which affects the cooling effect of the cooling devices on the casting machine and thus affects the working efficiency of the casting machine.

[0028] Based on this, this application provides a cooling device 1 for a casting machine. The cooling device 1 can spray coolant onto the casting machine, thereby cooling the casting machine. The coolant can be cooling water. The casting machine and the cooling device 1 can be arranged along the height direction of the casting machine. When the casting machine is arranged vertically, the cooling device 1 can be located below the casting machine. The inlet pipe 10 and the outlet pipe 20 can be arranged parallel to each other, and both the inlet pipe 10 and the outlet pipe 20 can extend along a first direction. When the cooling device 1 is arranged vertically... Figure 1 When setting the direction, the first direction can be... Figure 1 The Y-axis in the middle, the first direction is perpendicular to the height direction of the casting machine. The inlet pipe 10 and outlet pipe 20 can be arranged opposite each other and spaced apart along the second direction, when the cooling device 1... Figure 1 When setting the direction, the second direction can be... Figure 1The X-direction, the first direction, the second direction, and the height direction of the casting machine are perpendicular to each other. Multiple spray pipes 30 are arranged between the inlet pipe 10 and the outlet pipe 20. The multiple spray pipes 30 can all extend along the second direction, the multiple spray pipes 30 can be arranged sequentially along the first direction, and the multiple spray pipes 30 can be spaced apart. The interval between any two adjacent spray pipes 30 can be the same, so that the cooling device 1 can uniformly cool the casting machine and improve the cooling effect on the casting machine.

[0029] As an example, the two ends of the inlet pipe 10 along the first direction can be closed, and the side of the inlet pipe 10 away from the outlet pipe 20 along the second direction can be connected to a guide pipe 11. The guide pipe 11 can be located in the middle of the inlet pipe 10 along the first direction. Coolant can enter the inlet pipe 10 through the guide pipe 11, and the coolant can be diverted to multiple spray pipes 30.

[0030] Each spray pipe 30 is connected to an inlet pipe 10 and an outlet pipe 20. Coolant can enter the cooling device 1 through the inlet pipe 10, flow through multiple spray pipes 30, and be discharged through the outlet pipe 20. Each spray pipe 30 has a spray hole 31 located on the side of the corresponding spray pipe 30 facing the casting machine. Coolant can be sprayed onto the casting machine through the spray hole 31, thereby achieving the effect of cooling the casting machine. There can be multiple spray holes 31, with each spray pipe 30 having multiple spray holes 31. The multiple spray holes 31 of each spray pipe 30 are arranged sequentially along the length direction (i.e., the second direction) of the corresponding spray pipe 30, and can be evenly arranged along the second direction. At least two of the multiple spray holes 31 in each spray pipe 30 have different diameters. Spray holes 31 with different diameters can spray coolant at different flow rates, thus achieving different cooling effects. The arrangement of the spray holes 31 with different diameters can be set according to the temperature of the corresponding part of the casting machine. The spray holes 31 with larger diameters can be set to correspond to the parts of the casting machine with higher temperatures, and the spray holes 31 with smaller diameters can be set to correspond to the parts of the casting machine with lower temperatures. This achieves the effect of precise spraying of the casting machine by the cooling device 1, so that the cooling device 1 cools the casting machine evenly and the temperature of the casting machine is uniform. This is beneficial to improving the cooling effect of the casting machine, improving the working efficiency of the casting machine, and extending the service life of the casting machine.

[0031] As an example, along the second direction, the temperature of the parts near both ends of the casting machine can be lower than the temperature of the middle part of the casting machine. The larger diameter spray hole 31 can be set in the middle of the corresponding spray pipe 30, and the larger diameter spray hole 31 can spray coolant towards the middle part of the casting machine. The smaller diameter spray hole 31 can be set at both ends of the corresponding spray pipe 30 along the second direction, and the smaller diameter spray hole 31 can spray coolant towards the parts of the casting machine near both ends of the casting machine, so that the cooling device 1 can cool the casting machine evenly.

[0032] In some embodiments of this utility model, the multiple spray holes 31 of each spray pipe 30 form multiple spray hole groups, and the multiple spray hole groups are arranged sequentially along the length direction of the corresponding spray pipe 30. Each spray hole group includes multiple spray holes 31, and the diameter of the spray holes 31 in each spray hole group is the same.

[0033] Each spray pipe 30 has multiple spray holes 31, which can be divided into multiple spray hole groups according to their orifice diameter. Each spray hole group includes multiple spray holes 31, and the orifice diameters of the multiple spray holes 31 in each spray hole group are the same. Each spray hole group can cool a corresponding part of the casting machine. By setting multiple spray holes 31 in each spray hole group, it is beneficial to increase the cooling range of the spray hole group and improve the cooling efficiency of the casting machine. At least two spray hole groups have different orifice diameters, so that multiple spray hole groups can be used to cool different positions on the casting machine, and the temperature at different positions on the casting machine can be different. Multiple sets of spray nozzles can be arranged sequentially along the length of the corresponding spray pipe 30. Multiple sets of spray nozzles can be set to correspond to different parts of the casting machine along the height of the casting machine. The specific arrangement of multiple sets of spray nozzles can be set according to the temperature of the corresponding position of the casting machine. Spray nozzles 31 with larger diameters can be set to correspond to the parts of the casting machine with higher temperatures, and spray nozzles 31 with smaller diameters can be set to correspond to the parts of the casting machine with lower temperatures.

[0034] In some embodiments of this utility model, the multiple sets of spray holes include: a first spray hole group, a second spray hole group and a third spray hole group. The second spray hole group is located between the first spray hole group and the third spray hole group. The diameter of the spray holes in the second spray hole group is larger than that in the first spray hole group, and the diameter of the spray holes in the second spray hole group is larger than that in the third spray hole group.

[0035] In each spray pipe 30, at least two of the multiple spray hole groups have different orifice diameters, and each spray pipe 30 may include three spray hole groups. Along the second direction, the second spray hole group may be located between the first and third spray hole groups, and may be located at the middle position of the corresponding spray pipe 30. The second spray hole group can be used to cool the middle position of the casting machine along the second direction. The orifice diameter of the second spray hole group may be larger than that of the first spray hole group, and the orifice diameter of the second spray hole group may be larger than that of the third spray hole group. The orifice diameters of the first and third spray hole groups may be the same, or they may be different.

[0036] The larger diameter spray nozzle 31 can spray more coolant, resulting in better cooling. This means the second spray nozzle group can spray more coolant into the casting machine, providing a greater cooling effect and lowering the temperature of corresponding parts of the casting machine. The temperature reduction achieved by the first and third spray nozzle groups is less than that achieved by the second spray nozzle group. Along the second direction, the temperature in the middle of the casting machine can be higher than that near the ends. The second spray nozzle group can cool the hotter parts of the casting machine, while the first and third spray nozzle groups can cool the cooler parts, thus ensuring uniform temperature distribution and improving the casting machine's efficiency.

[0037] In some embodiments of this utility model, the nozzle diameters of the first nozzle group and the third nozzle group are different.

[0038] The cooling effect of the first group of spray nozzles on the corresponding parts of the casting machine differs from that of the third group of spray nozzles. Along the height of the casting machine, the smaller-diameter nozzle in the first and third groups can be positioned near the end of the casting machine with a lower temperature along the second direction, while the larger-diameter nozzle in the first and third groups can be positioned near the end of the casting machine with a higher temperature along the second direction, thus ensuring uniform cooling of the casting machine.

[0039] In some embodiments of this utility model, all of the multiple spray holes 31 are circular holes; the diameter of the spray holes in the first spray hole group is D1, satisfying the relationship: 3mm≤D1≤5mm; and / or the diameter of the spray holes in the second spray hole group is D2, satisfying the relationship: 5mm≤D2≤7mm; and / or the diameter of the spray holes in the third spray hole group is D3, satisfying the relationship: 4mm≤D3≤6mm.

[0040] Multiple injection holes 31 can all be constructed as circular holes, thereby reducing the influence of the shape of the injection holes 31 on the flow rate of the coolant ejected from the corresponding injection holes 31. The multiple injection holes 31 of each injection pipe 30 form multiple groups of injection holes, and the injection hole diameters of the first group of injection holes, the second group of injection holes, and the third group of injection holes are all different.

[0041] For example, the nozzle diameter of the first spray hole group can be 3mm, 3.6mm, 4mm, 4.3mm, 5mm, etc. Any nozzle diameter within the range of 3mm to 5mm, including endpoint values, is a selectable nozzle diameter for the first spray hole group in this invention. If the nozzle diameter of the first spray hole group is less than 3mm, the flow rate of coolant sprayed from the nozzle 31 of the first spray hole group will be too low, affecting the cooling effect of the cooling device 1 on the casting machine. If the nozzle diameter of the first spray hole group is greater than 5mm, the flow rate of coolant sprayed from the nozzle 31 of the first spray hole group will be large, resulting in excessive temperature drop at the corresponding part of the casting machine and the first spray hole group. This can easily lead to uneven temperature distribution in the casting machine, affecting its working efficiency and service life.

[0042] For example, the nozzle diameter of the third spray hole group can be 4mm, 4.6mm, 5mm, 5.3mm, 6mm, etc. The nozzle diameter of the third spray hole group can be within the range of 4mm to 6mm, including any value including the endpoint values. The nozzle diameter of the third spray hole group can be the same as that of the first spray hole group, or it can be different from that of the first spray hole group. If the nozzle diameter of the third spray hole group is less than 4mm, the flow rate of coolant sprayed from the nozzle 31 of the third spray hole group is low, affecting the cooling effect of the cooling device 1 on the casting machine. If the nozzle diameter of the third spray hole group is greater than 6mm, the flow rate of coolant sprayed from the nozzle 31 of the third spray hole group is high, resulting in excessive temperature drop at the corresponding part of the casting machine and the third spray hole group. This can easily lead to uneven temperature distribution in the casting machine, affecting its working efficiency and service life.

[0043] For example, the nozzle diameter of the second spray hole group can be 5mm, 5.6mm, 6mm, 6.3mm, 7mm, etc. Any nozzle diameter within the range of 5mm to 7mm, including endpoint values, is a selectable nozzle diameter for the second spray hole group in this invention. If the nozzle diameter of the second spray hole group is less than 5mm, the flow rate of coolant sprayed from the nozzle 31 of the second spray hole group is low, affecting the cooling effect of the cooling device 1 on the casting machine. If the nozzle diameter of the second spray hole group is greater than 7mm, the flow rate of coolant sprayed from the nozzle 31 of the second spray hole group is high, resulting in excessive temperature drop at the corresponding part of the casting machine and the second spray hole group. This can easily lead to uneven temperature distribution in the casting machine, affecting its working efficiency and service life.

[0044] The nozzle diameter of the second spray hole group is larger than that of the first spray hole group, and the nozzle diameter of the second spray hole group is larger than that of the third spray hole group. The nozzle diameters of the first and third spray hole groups can be the same, or they can be different. This application uses an embodiment where the nozzle diameter of the first spray hole group is smaller than that of the third spray hole group, and the nozzle diameter of the third spray hole group is smaller than that of the second spray hole group, as an example for illustration.

[0045] In some embodiments of this utility model, the number of spray holes 31 formed in each spray pipe 30 is N, which satisfies the relationship: 8≤N≤12, where N is a positive integer.

[0046] Each spray pipe 30 has a plurality of spray holes 31, which are arranged sequentially along a second direction on the corresponding spray pipe 30. For example, the number of spray holes 31 formed in each spray pipe 30 can be 8, 9, 10, 11, or 12. The number of spray holes 31 formed in each spray pipe 30 can be within the range of 8 to 12, including any value including endpoint values. If the number of spray holes 31 in each spray pipe 30 is less than 8, the small number of spray holes 31 in each spray pipe 30 will affect the cooling range of the cooling device 1 on the casting machine, potentially causing some parts of the casting machine to remain uncooled, thus affecting the cooling effect of the cooling device 1 on the casting machine. If the number of spray holes 31 in each spray pipe 30 is greater than 12, the excessive number of spray holes 31 in each spray pipe 30 will affect the internal pressure of the cooling device 1, which may lead to insufficient internal pressure of the cooling device 1 and the inability of the coolant to be sprayed onto the surface of the casting machine, thus affecting the cooling of the casting machine by the cooling device 1.

[0047] In some embodiments of this utility model, at least one end of the liquid outlet pipe 20 is provided with a drain port 21, and the drain port 21 is provided with a drain valve, which selectively opens the drain port 21.

[0048] One end of the liquid outlet pipe 20 may have a drain port 21, or both ends of the liquid outlet pipe 20 may have drain ports 21. This embodiment uses the example of one end of the liquid outlet pipe 20 having a drain port 21. The drain port 21 may be equipped with a drain valve, which can selectively open or close the drain port 21, thereby allowing the liquid outlet pipe 20 to be selectively opened or closed. The drain valve may be a solenoid valve, which can be electrically controlled to open or close the drain port 21. Alternatively, the drain valve may be a mechanical valve structure, which can be manually controlled to open or close the drain port 21.

[0049] When the cooling device 1 is used to cool the casting machine, the outlet pipe 20 can be closed, allowing the cooling device 1 to be filled with coolant, which can then be sprayed out from multiple spray holes 31. When the cooling device 1 needs to be cleaned, the outlet pipe 20 can be opened, allowing cleaning water to enter the cooling device 1 from the inlet pipe 10. The cleaning water can flow through multiple spray pipes 30, carrying away impurities in the pipes and being discharged through the outlet pipe 20. The cleaning of the cooling device 1 can be achieved simply by controlling the opening and closing of the drain valve. This simple operation increases the cleaning speed of the cooling device 1, ensuring its cleanliness and thus guaranteeing its cooling effect on the casting machine.

[0050] As an example, the drain outlet 21 can be open to the ground. When the cleaning water flows out of the drain outlet 21, the cleaning water containing impurities can flow to the collection device under the action of gravity, which is convenient for collecting the cleaning water containing impurities and is easy to operate.

[0051] In some embodiments of this utility model, the inlet pipe 10 and the outlet pipe 20 are opposite to each other and spaced apart. The inlet pipe 10 and the outlet pipe 20 both extend in the same direction. A plurality of spray pipes 30 are arranged sequentially along the extension direction of the inlet pipe 10. Each spray pipe 30 extends along the arrangement direction of the inlet pipe 10 and the outlet pipe 20 and is connected between the inlet pipe 10 and the outlet pipe 20.

[0052] The inlet pipe 10 and outlet pipe 20 can be arranged opposite to each other and spaced apart along a second direction, or they can be arranged parallel to each other. Both the inlet pipe 10 and outlet pipe 20 can extend along a first direction. Multiple spray pipes 30 are arranged sequentially along the extension direction of the inlet pipe 10 (i.e., the first direction), thereby increasing the heat exchange area between the cooling device 1 and the casting machine, which is beneficial for improving the heat dissipation effect of the casting machine. Each spray pipe 30 is located between the inlet pipe 10 and the outlet pipe 20, and each spray pipe 30 can extend along the second direction. Multiple spray pipes 30 are connected between the inlet pipe 10 and the outlet pipe 20, and are in communication with both the inlet pipe 10 and the outlet pipe 20. The coolant can flow within the cooling device 1, and the coolant can fill the cooling device 1, thereby achieving the effect of the coolant being sprayed out through the spray hole 31 and cooling the casting machine.

[0053] In some embodiments of this utility model, the interval between any two adjacent spray pipes 30 is the same.

[0054] Multiple spray pipes 30 are spaced apart, and the distance between any two adjacent spray pipes 30 is the same, so that the cooling device 1 can cool the casting machine evenly, which is beneficial to improving the cooling effect on the casting machine.

[0055] The casting machine according to a second aspect of the present invention includes the cooling device 1 for the casting machine described in the above embodiments.

[0056] According to the embodiments of this application, the casting machine using the cooling device 1 for the casting machine in the above embodiments can improve the cooling effect of the casting machine, improve the working efficiency of the casting machine, ensure the quality of the products produced by the casting machine, and help extend the service life of the casting machine.

[0057] The other components and operation of the cooling device 1 and the casting machine according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
