Description

Technical Field

[0001] The present invention relates to the technical field of casting cooling, in particular to a casting mold side mold, a side mold water cooling system and a cooling method. Background Art

[0002] Aluminum alloy wheels are mostly formed by pressure casting. High-temperature aluminum is hydraulically pressed into the mold cavity. After maintaining the pressure for a period of time, the mold is opened to form a wheel blank. Through subsequent cleaning and processing, aluminum alloy wheels that meet dimensional accuracy requirements are obtained. This has the advantages of high production efficiency, good casting quality, and high material utilization.

[0003] In the aluminum alloy pressure casting process, in order to further improve efficiency, water cooling is currently used instead of compressed air cooling (such as publication number CN117548644A). Cooling chambers are set in the upper mold, side mold and lower mold. The cooling chambers are connected to the liquid inlet pipe and the liquid discharge pipe. The cooling medium is used to exchange heat with the corresponding upper mold, side mold and lower mold to reduce the temperature of the mold itself, thereby reducing the temperature of the aluminum alloy wheel hub blank.

[0004] The existing side mold cooling chamber is arranged along the arc direction of the side mold to form an arc-shaped chamber. One end of the arc-shaped chamber is connected to the liquid inlet pipe, and the other end is connected to the liquid discharge pipe. The pressure loss is large, and the cooling medium in the arc-shaped chamber flows unevenly, which is very likely to cause local overheating or overcooling. Moreover, the arc-shaped cooling chamber can only achieve local cooling within the same horizontal plane, and the wheel hub cooling effect is poor. In addition, the existing cooling medium directly enters the side mold cooling chamber, and the cooling medium temperature is too low, which can easily cause thermal shock to the side mold, seriously affecting the service life of the side mold. Summary of the Invention

[0005] In order to solve the technical problems in the above background technology that local overheating or overcooling easily occurs in the water-cooling chamber of the side mold, the cooling effect is poor, and only local cooling can be achieved, the present invention provides a casting mold side mold.

[0006] The technical solutions of the present invention are as follows: The present invention provides a side mold of a casting mold, comprising a side mold main body, on which an inlay is detachably mounted, which facilitates replacement and maintenance of the inlay and reduces the cost of use, and a cooling chamber is provided in the inlay; the cooling chamber comprises a transversely arranged first chamber, which extends along the arc direction of the inlay, at least one end of the two ends of the first chamber is a water outlet, and the first chamber is connected to a plurality of water inlets, which are located below the first chamber and are spaced apart along the length direction of the first chamber. The arrangement of the plurality of water inlets realizes point-in and ring-out of a cooling medium of the side mold, enables the cooling medium to flow evenly in the side mold, effectively avoids local overheating or overcooling, and makes the temperature of various parts of the side mold more uniform, thereby ensuring uniform shrinkage everywhere during the product molding process, improving the dimensional accuracy and surface quality of the product, reducing defects such as deformation and warping caused by uneven cooling, and at the same time helping to reduce the pressure loss of the cooling medium in the flow channel, making the operation of the cooling system more stable and efficient, so as to reduce the power consumption of equipment such as a cooling pump and reduce energy costs while ensuring the cooling effect.

[0007] Preferably, a plurality of second chambers are provided above the first chamber at intervals along its length direction. The second chambers are arranged vertically and communicated with the first chamber. The arrangement of the second chambers further increases the flow space and path of the cooling medium, so that the cooling medium can more fully contact the side mold, thereby improving the cooling effect, helping to quickly take away the heat of the side mold, reducing the cooling time of the casting, and improving production efficiency.

[0008] Preferably, the lower end of the second chamber is connected to the first chamber through a water inlet, and the water inlet is arranged horizontally, so that the second chamber and the first chamber are located in different vertical planes, avoiding local heat exchange in the same plane, effectively improving the heat exchange effect and efficiency, and there is no need to open a large-volume chamber, saving the use of cooling medium.

[0009] Preferably, a sealing piece is detachably installed on the top of the second chamber, and the sealing piece can be used to seal the top of the second chamber to limit the discharge of water vapor. Under the action of water vapor, the height to which the cooling medium rises in the second chamber can be limited, and strong cooling will not be performed on the weak position of the rim (such as the upper edge of the rim); when strong cooling is required on the weak position of the hub, only the sealing piece needs to be removed, which is easy to operate and has strong overall adaptability.

[0010] A side mold water cooling system includes a casting mold side mold, a cooling chamber inside the inlay is connected to a cooling medium supply mechanism via a water outlet pipe and a water inlet pipe, a preheating mechanism is provided on the water inlet pipe, and the cooling chamber is connected to the cooling medium supply mechanism via the water outlet pipe and the water inlet pipe, thereby realizing the circulation of the cooling medium and ensuring the continuous cooling of the side mold. The setting of the preheating mechanism can preheat the cooling medium entering the cooling chamber, thereby avoiding thermal shock to the side mold caused by excessively low cooling medium temperature, and extending the service life of the side mold.

[0011] Preferably, a heat exchange mechanism is provided between the water outlet pipe and the water inlet pipe. The heat exchange mechanism can exchange heat between the high-temperature cooling medium discharged from the water outlet pipe and the low-temperature cooling medium in the water inlet pipe, thereby realizing heat recovery and utilization, assisting the preheating work of the preheating mechanism, effectively improving the heating efficiency of the cooling medium, reducing energy consumption, and improving energy utilization efficiency.

[0012] Preferably, the preheating mechanism includes a shell, a medium heat exchange channel is provided in the shell, a heating layer is provided on the outside of the medium heat exchange channel, and the medium heat exchange channel includes a first spiral channel. The setting of the first spiral channel increases the flow path and residence time of the cooling medium in the preheating mechanism, so that the cooling medium can more fully exchange heat with the heating layer, thereby improving the preheating effect and ensuring that the temperature of the cooling medium entering the cooling chamber meets the requirements.

[0013] Preferably, the medium heat exchange channel includes a second spiral channel, the first spiral channel and the second spiral channel are concentrically arranged, the rotation directions of the first spiral channel and the second spiral channel are opposite, and there is at least one confluence between the first spiral channel and the second spiral channel. The double-helix channel structure, based on the spiral extended flow path, the media in the two spiral channels flow in opposite directions, and strong disturbances and vortices will be formed at the medium confluence, breaking the laminar state of the fluid, making the molecular motion inside the fluid more intense, promoting the diffusion and transfer of heat, and improving temperature uniformity.

[0014] Preferably, the spiral diameter of the water inlet end of the medium heat exchange channel is smaller than that of the water outlet end, so that the fluid encounters greater resistance when entering the channel, thereby reducing the flow rate of the fluid, allowing the fluid to have more time to exchange heat with the channel wall, improving the adequacy of the heat exchange, and avoiding incomplete reaction due to excessive flow rate.

[0015] A cooling method comprises the following steps: assembling a mold and pressing high-temperature molten aluminum into the mold, and starting pressure maintenance after the molten aluminum fills the molding chamber, and water cooling is performed during the pressure maintenance; in the process of a cooling medium supply mechanism supplying cooling medium to the side mold, a preheating mechanism preheats the cooling medium; the cooling medium after heat exchange in the cooling chamber is discharged to the cooling medium supply mechanism through a water outlet pipe, the cooling medium in the water outlet pipe exchanges heat with the heat exchange mechanism for cooling, and the cooling medium in the water inlet pipe exchanges heat with the heat exchange mechanism for heating; water cooling is performed during the pressure maintenance to quickly reduce the temperature of the side mold and the casting, thereby improving the molding quality and production efficiency of the casting; the preheating mechanism preheats the cooling medium, thereby avoiding thermal shock and extending the service life of the side mold; the heat exchange mechanism realizes heat recovery and utilization, and can assist the preheating work of the preheating mechanism, thereby effectively improving the heating efficiency of the cooling medium, reducing energy consumption, and improving energy utilization efficiency.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are: 1. An inlay is detachably mounted on the side mold body, and a cooling chamber is provided in the inlay, which facilitates replacement and maintenance. The cooling chamber is connected to several water inlets, realizing point-in and loop-out of the cooling medium of the side mold, and enabling the cooling medium to flow evenly in the side mold, effectively avoiding local overheating or overcooling, and making the temperature of each part of the side mold more uniform, thereby ensuring uniform shrinkage in all parts during the product molding process, improving the dimensional accuracy and surface quality of the product, and reducing defects such as deformation and warping caused by uneven cooling. At the same time, it helps to reduce the pressure loss of the cooling medium in the flow channel, making the operation of the cooling system more stable and efficient, so as to reduce the power consumption of equipment such as the cooling pump and reduce energy costs while ensuring the cooling effect.

[0017] 2. The first chamber is arranged horizontally, and the second chamber is arranged vertically, and the first chamber and the second chamber are located in different vertical planes, which avoids local heat exchange in the same plane, effectively improves the heat exchange effect and efficiency, and does not require the opening of a large-volume chamber, saving the use of cooling medium.

[0018] 3. A preheating mechanism and a heat exchange mechanism are set on the circulating water circuit of the side mold water cooling system. The setting of the preheating mechanism can preheat the cooling medium entering the cooling chamber to avoid thermal shock to the side mold caused by the cooling medium temperature being too low, thereby extending the service life of the side mold. The heat exchange mechanism can exchange heat between the high-temperature cooling medium discharged from the outlet pipe and the low-temperature cooling medium in the inlet pipe, realizing heat recovery and utilization, assisting the preheating work of the preheating mechanism, effectively improving the heating efficiency of the cooling medium, reducing energy consumption, and improving energy utilization efficiency.

DETAILED DESCRIPTION

[0021] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0022] Example 1 In a typical embodiment of the present invention, a side mold of a casting mold is proposed, comprising: a side mold body 1 and an inlay 2, the inlay 2 being detachably mounted on the side mold body 1, a cooling chamber being provided inside the inlay 2, the cooling chamber being used to be connected to a cooling medium supply mechanism through a circulation pipeline, the cooling medium supply mechanism being used to supply the cooling medium, the cooling medium flowing into the cooling chamber in the inlay 2 through the circulation pipeline to perform water-cooled heat exchange. The combined use of the inlay 2 and the side mold body 1 can concentrate local damage to the cooling chamber on the inlay 2, thereby only requiring replacement of the inlay 2, thereby effectively reducing the cost of using the side mold.

[0023] like Figure 1 and Figure 2 As shown, the cooling chamber includes a first chamber 3 and a second chamber 4. The first chamber 3 is provided with one, the first chamber 3 is arranged horizontally and extends along the arc direction of the inlay 2, and the second chamber 4 is provided with several, the second chamber 4 is arranged vertically, and the several second chambers 4 are arranged at intervals along the length direction of the first chamber 3. The bottom of the second chamber 4 is connected with the first chamber 3, and the second chamber 4 and the first chamber 3 are staggered, that is, the second chamber 4 and the first chamber 3 are located in different vertical planes, avoiding local heat exchange in the same plane, effectively improving the heat exchange effect and efficiency, and there is no need to open a large-volume chamber, saving the use of cooling medium.

[0024] A plurality of water inlets 6 are provided at intervals on the bottom of the inlay 2. Specifically, the water inlet 6 is located below the first chamber 3, and the plurality of water inlets 6 are spaced apart along the length direction of the first chamber 3. The water inlet 6 is used to connect to the circulation pipeline. At least one of the two ends of the first chamber 3 is a water outlet, and the water outlets at both ends of the first chamber 3 are provided with internal threads for connection with the blocking member 7, so that the blocking member 7 can be used to block the water outlets at both ends of the first chamber 3, thereby controlling the discharge path and efficiency of the cooling medium. The plurality of water inlets 6 are spaced apart along the length direction of the first chamber 3 and are all connected to the first chamber 3, realizing the side mold cooling. The cooling medium enters at a point and exits in a ring, that is, water enters from a point (water inlet 6) and exits through a ring path (first chamber 3), which enables the cooling medium to flow evenly in the side mold, effectively avoiding local overheating or overcooling, and making the temperature of each part of the side mold more uniform, thereby ensuring uniform shrinkage in all parts during the product molding process, improving the dimensional accuracy and surface quality of the product, and reducing defects such as deformation and warping caused by uneven cooling. At the same time, it helps to reduce the pressure loss of the cooling medium in the flow channel, making the operation of the cooling system more stable and efficient, so as to reduce the power consumption of equipment such as the cooling pump and reduce energy costs while ensuring the cooling effect.

[0025] It is understandable that the blocking member 7 can be a long strip structure with external threads such as a screw plug, which can be installed by threaded connection. The specific structural form of the blocking member 7 can be determined according to actual design requirements, and no excessive restrictions will be made here.

[0026] In this embodiment, the water inlet 6 is formed by positioning perforation so that the water inlet 6 can be accurately set at the key position that requires cooling. It can perform targeted cooling on the areas with higher temperatures in the mold, improve the cooling efficiency, better control the mold temperature, and help improve production efficiency and shorten the molding cycle. The water inlet 6 is provided with an internal thread for the installation of the sealing part 7, so that the sealing part 7 can be used to seal the designated water inlet 6, and the overall adaptability is strong.

[0027] like Figure 1 and Figure 2As shown, a number of water inlets 5 are also provided in the inlay 2, and the water inlets 5 are arranged horizontally. The number of the water inlets 5 is the same as the number of the second chambers 4 and corresponds one to one. The lower end of the second chamber 4 is connected to the first chamber 3 through the water inlet 5, and the water inlet 5 and the first chamber 3 are in the same horizontal plane, so that the cooling medium can flow into the second chamber 4 through the water inlet 5. The top of the second chamber 4 is provided with an internal thread, and a sealing member 7 is detachably installed on the top of the second chamber 4. The sealing member 7 can be used to seal the top of the second chamber 4 to limit the discharge of water vapor. Under the action of water vapor, the height of the cooling medium rising in the second chamber 4 can be limited, and the weak position of the rim (such as the upper edge of the rim) will not be strongly cooled; when the weak position of the hub needs to be strongly cooled, it is only necessary to remove the sealing member 7.

[0028] Example 2 In another typical embodiment of the present invention, a side mold water cooling system is proposed, including: a side mold body 1, an inlay 2, a circulation pipeline, a preheating mechanism 8 and a cooling medium supply mechanism 14. The inlay 2 can be detachably installed in the side mold body 1. A cooling chamber is provided inside the inlay 2, and the cooling chamber is connected to the cooling medium supply mechanism 14 through a circulation pipeline. The preheating mechanism 8 is arranged on the water inlet pipeline 17 between the cooling medium supply mechanism 14 and the inlay 2. The cooling medium supply mechanism 14 is used to supply the cooling medium. The cooling medium flows into the cooling chamber in the inlay 2 through the circulation pipeline to perform water cooling heat exchange. The preheating mechanism 8 is used to preheat the cooling medium entering the inlay 2 so that the temperature of the cooling medium is the same as the initial working temperature of the side mold (that is, the combination of the side mold body 1 and the inlay 2) to reduce the thermal shock on the mold caused by the low temperature of the cooling medium, thereby effectively improving the overall service life of the side mold. The combined use of the inlay 2 and the side mold body 1 can concentrate local damage to the cooling chamber on the inlay 2, so that the inlay 2 can be replaced, thereby effectively reducing the cost of using the side mold.

[0029] like Figure 3 As shown, the preheating mechanism 8 includes a shell 9, a heating layer 10 and a medium heat exchange channel 11. The heating layer 10 is fixedly arranged in the shell 9 for heating the cooling medium. The medium heat exchange channel 11 is fixedly installed in the shell 9, and the heating layer 10 is sleeved on the circumference of the medium heat exchange channel 11. The medium heat exchange channel 11 is used for the circulation of the cooling medium. The cooling medium is heated by the outer heating layer 10 during the flow process. The shell 9 is a heat insulation layer made of heat insulation material to improve the safety of use and avoid accidents such as scalding. The water inlet end of the medium heat exchange channel 11 is connected to the cooling medium supply mechanism, and the water outlet end of the medium heat exchange channel 11 is connected to the water inlet 6 of the side mold through a pipeline. The cooling medium supplied by the cooling medium supply mechanism 14 flows through the medium heat exchange channel 11 for preheating. After preheating, the cooling medium flows into the first chamber 3 through the water inlet 6 to perform heat exchange cooling.

[0030] The heating layer 10 includes several groups of heating units, which are evenly arranged around the medium heat exchange channel 11, and each group of heating units is independently controlled to achieve zoned heating and improve the heating efficiency and effect of the cooling medium.

[0031] It is understandable that the heating unit can be an electric heating structure such as a heating plate or a heating rod. The specific structural form can be selected according to actual needs and no excessive restrictions are imposed here.

[0032] In this embodiment, the medium heat exchange channel 11 is a single spiral channel, that is, the medium heat exchange channel 11 includes a first spiral channel 12 to extend the residence time of the cooling medium in the channel, increase the contact area with the heating layer 10, and improve the heat exchange efficiency. In order to further improve the heat exchange efficiency, a number of guide vanes are fixedly provided on the inner wall of the medium heat exchange channel 11. The guide vanes are made of a copper alloy material with high thermal conductivity. One end of the guide vane is fixedly connected to the inner wall of the medium heat exchange channel 11, and the other end extends toward the center of the medium heat exchange channel 11 but does not contact it. The guide vane is used to change the flow path of the cooling medium to form turbulence and enhance the convective heat transfer effect; at the same time, the guide vane increases the heat exchange area and accelerates heat transfer.

[0033] In other embodiments, the medium heat exchange channel 11 may also be a double helical channel, specifically as follows Figure 4 As shown, the medium heat exchange channel 11 includes a first spiral channel 12 and a second spiral channel 13. The first spiral channel 12 and the second spiral channel 13 are concentrically arranged. The rotation directions of the first spiral channel 12 and the second spiral channel 13 are opposite. There is at least one point between the first spiral channel 12 and the second spiral channel 13 where they intersect and are connected, that is, there is at least one confluence between the first spiral channel 12 and the second spiral channel 13. The water inlet ends of the first spiral channel 12 and the second spiral channel 13 are both connected to the cooling medium supply mechanism 14, and the water outlet ends of the first spiral channel 12 and the second spiral channel 13 are both connected to the water inlet 6 through pipelines. The double-helix channel structure, based on the spiral extended flow path, the media in the two spiral channels flow in opposite directions, and strong disturbances and vortices will be formed at the medium confluence, breaking the laminar state of the fluid, making the molecular motion inside the fluid more intense, promoting heat diffusion and transfer, and improving temperature uniformity.

[0034] like Figure 4 As shown, the spiral diameter of the water inlet end of the double-helix channel is smaller than that of the water outlet end, which can make the fluid encounter greater resistance when entering the channel, thereby reducing the flow rate of the fluid, allowing the fluid to have more time to exchange heat with the channel wall, improving the adequacy of heat exchange, and avoiding incomplete reaction due to excessive flow rate.

[0035] In this embodiment, a heat exchange plate is arranged between the heating layer 10 and the medium heat exchange channel 11. The heat exchange plate is covered with micron-level heat exchange channels. The heat generated by the heating layer 10 is quickly transferred to the cooling medium through the heat exchange channel, which can further improve the heat transfer efficiency.

[0036] like Figure 5 As shown, a heat exchange mechanism 15 is provided on the circulation pipeline between the preheating mechanism 8, the cooling medium supply mechanism 14 and the side mold. The heat exchange mechanism 15 is located on the water inlet side of the preheating mechanism 8. The heat exchange mechanism 15 is a heat exchanger. The cooling medium discharged from the cooling chamber in the side mold exchanges heat with the heat exchange mechanism 15 when flowing back to the cooling medium supply mechanism 14 to realize heat storage. Before the cooling medium enters the preheating mechanism 8, the cooling medium exchanges heat with the heat exchange mechanism 15 in advance and absorbs the heat stored in the heat exchange mechanism 15 to preheat the cooling medium. This can effectively reduce the energy waste of the preheating mechanism 8 and improve the preheating efficiency of the cooling medium.

[0037] Example 3 In another typical embodiment of the present invention, a cooling method is proposed, which uses the side mold water cooling system in Example 2, specifically as follows: Install the inlay 2 in the side mold body 1, and match the assembled multiple side molds with the upper mold and the lower mold to form a spoke molding cavity and a hub molding cavity that are interconnected; Connect one water outlet of the first chamber 3 in the inlay 2 to the water inlet of the cooling medium supply mechanism 14 through the water outlet pipe 16. At the same time, connect the water inlets 6 at several designated positions to the water outlet of the preheating mechanism 8 through the water inlet pipe 17. The water inlet of the preheating mechanism 8 is connected to the water outlet of the cooling medium supply mechanism 14 through the pipe. A heat exchange mechanism 15 is provided on the water outlet pipe 16 and the water inlet pipe 17. The press presses high-temperature molten aluminum into the spoke forming chamber and the rim forming chamber through the liquid inlet until the high-temperature molten aluminum completely fills the spoke forming chamber and the rim forming chamber, starts to maintain pressure, and performs water cooling.

[0038] The specific process of water cooling is: The cooling medium supply mechanism 14 supplies liquid to the medium heat exchange channel 11 of the preheating mechanism 8, starts the heating layer 10, and uses the heating layer 10 to heat the cooling medium in the medium heat exchange channel 11, and heats the cooling medium to the same initial working temperature as the side mold (i.e., the combination of the side mold body 1 and the inlay 2). After the cooling medium is preheated, it is transported to the designated water inlet 6 through the water inlet pipe 17, and is transported to the first chamber 3 through the water inlet 6. The cooling medium in the first chamber 3 flows into the vertically arranged second chamber 4 through the water inlet 5, avoiding local heat exchange in the same plane, effectively improving the heat exchange effect and Efficiency: water enters from the point (water inlet 6) and exits through the annular path (first chamber 3), which enables the cooling medium to flow evenly within the side mold, effectively avoiding local overheating or overcooling, making the temperature of each part of the side mold more uniform, thereby ensuring uniform shrinkage throughout the product molding process, improving the dimensional accuracy and surface quality of the product, and reducing defects such as deformation and warping caused by uneven cooling. At the same time, it helps to reduce the pressure loss of the cooling medium in the flow channel, making the operation of the cooling system more stable and efficient. Under the premise of ensuring the cooling effect, it can reduce the power consumption of equipment such as the cooling pump and reduce energy costs; The cooling medium after heat exchange in the cooling chamber is discharged to the cooling medium supply mechanism 14 through the water outlet pipe 16 for cooling. During the discharge, the cooling medium exchanges heat with the heat exchange mechanism 15, and the heat exchange mechanism 15 is used to store heat. The heat exchange mechanism 15 exchanges heat with the cooling medium in the water inlet pipe 17 to increase its temperature, so as to assist the preheating work of the preheating mechanism 8 and reduce energy consumption. Specifically, the cooling medium discharged from the cooling medium supply mechanism 14 first passes through the heat exchange mechanism 15 for heat exchange and temperature increase. The cooling medium after heat exchange and temperature increase enters the preheating mechanism 8 for further heating, with high heating efficiency and low heating energy consumption.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
