Description

Technical Field

[0001] The present application relates to the technical field of metal casting, and in particular to a casting system and a casting process for aluminum alloy castings. Background Art

[0002] Aluminum alloy castings refer to equipment and devices made of pure aluminum or aluminum alloys by casting. Generally, a sand mold or a metal mold is used to pour the heated liquid aluminum or aluminum alloy into the mold cavity, and the aluminum parts or aluminum alloy parts of various shapes and sizes obtained are usually called aluminum die castings.

[0003] During the production and processing of aluminum alloy castings, it is usually necessary to use a casting system to cast the aluminum alloy casting liquid into the mold for molding processing to ensure the production speed of the aluminum alloy castings. At the same time, in order to ensure the casting quality of the aluminum alloy casting liquid, it is usually necessary to add a defoaming agent and a thickener to the casting liquid to avoid a large amount of foam in the casting liquid, which causes defects on the casting surface. At the same time, it can ensure the stability, fluidity and viscosity of the casting liquid, reduce the liquid reflux and shrinkage cavities of the casting liquid, so as to ensure the casting effect of the casting liquid.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: when the current casting system adds defoamers and thickeners to the aluminum alloy casting liquid, it is not convenient to automatically adjust the amount and speed of the defoamers and thickeners according to the viscosity and temperature of the aluminum alloy casting liquid, so that the arbitrary addition of defoamers and thickeners during the casting of the aluminum alloy casting liquid will cause a series of problems: When the viscosity of aluminum alloy casting liquid is relatively high, if too much thickener is poured, the fluidity of the casting liquid will be significantly reduced, making it difficult for the casting liquid to flow smoothly during the casting process, which may cause the casting liquid to be unable to fully fill the mold and cause casting defects. If too much defoaming agent is poured, certain components in the casting liquid will react to form precipitates or colloids, which may increase the viscosity of the casting liquid and reduce the fluidity of the casting liquid. When the temperature of the aluminum alloy casting liquid is high, if the thickener is poured too quickly, the thickener will lose its thickening effect or undergo irreversible viscosity changes under high temperature conditions, resulting in performance degradation. If the defoamer is poured too quickly, the defoamer will become ineffective and decompose or lose its activity at high temperatures, resulting in a weakened defoaming effect. The improvement effect of the defoamer and thickener on the aluminum alloy casting liquid cannot be guaranteed. Summary of the invention

[0005] In order to solve the problem that the current casting system is not convenient for automatically adjusting the addition amount and addition speed of defoaming agent and thickener according to the viscosity and temperature of the aluminum alloy casting liquid when adding defoaming agent and thickener during casting aluminum alloy casting liquid, the present application provides a casting system and casting process for aluminum alloy castings.

[0007] By adopting the above technical scheme, the casting liquid in the casting tank can be stirred by the processing mechanism, and the processed casting liquid can be molded at the same time. The temperature and viscosity of the overall casting liquid in the casting tank can be detected by the overall detection mechanism in combination with the stirring member. The adding speed and amount of the defoamer and the thickener can be controlled according to the temperature and viscosity of the overall casting liquid in the casting tank by the control component in combination with the stirring member. The temperature and viscosity of the casting liquid at different heights in the casting tank can be detected by the local detection mechanism in combination with the stirring member. The adding speed and amount of the defoamer and the thickener can be controlled according to the temperature and viscosity of the casting liquid at different heights in the casting tank by the feeding mechanism in combination with the stirring member. The viscosity and temperature of the casting liquid at different heights in the casting tank are different. Therefore, it is necessary to control the amount and speed of adding the defoamer and thickener according to the viscosity and temperature of the casting liquid at different heights in the casting tank. However, the defoamer and thickener are usually added from the top of the casting tank, so that the defoamer and thickener will preferentially defoam and improve the casting liquid above the casting tank. If the defoamer and thickener are not evenly mixed with the casting liquid, the defoaming effect and viscosity improvement effect of the casting liquid at different heights in the casting tank will be different, resulting in the problems of unstable casting quality, uneven fluidity, poor defoaming effect and reduced casting dimensional accuracy. The adjusting part cooperates with the adjusting part and the stirring part to detect the viscosity of the overall casting liquid in the casting tank. When the viscosity of the overall casting liquid in the casting tank is large, the total amount of thickener and defoamer added can be reduced. When the viscosity of the overall casting liquid in the casting tank is small, the total amount of thickener and defoamer added can be increased. The total amount of thickener and defoamer added can be automatically controlled according to the viscosity of the overall casting liquid in the casting tank. The connecting piece cooperates with the amount control piece and the stirring piece to detect the viscosity of the casting liquid at different heights in the casting tank. When the viscosity of the local casting liquid in the casting tank is large, the total amount of thickener and defoamer added can be reduced. When the viscosity of the local casting liquid in the casting tank is small, the total amount of thickener and defoamer added can be increased. The total amount of thickener and defoamer added can be automatically controlled according to the viscosity of the overall casting liquid in the casting tank. The thickener and defoamer can be added at different heights in the casting tank, so that the defoamer and thickener can defoam and improve the viscosity of the casting liquid at different heights in the casting tank. The viscosity of the aluminum alloy casting liquid is large. It is best to avoid excessive casting of thickener, which will significantly reduce the fluidity of the casting liquid, prevent the casting liquid from flowing smoothly during casting, and avoid casting defects caused by the inability of the casting liquid to fully fill the mold. It is also best to avoid excessive casting of defoamer, which will cause certain components in the casting liquid to react to form precipitation or colloidal substances, thereby reducing the fluidity of the casting liquid. The limiter, speed regulating part and stirring part can detect the temperature of the overall casting liquid in the casting tank. When the temperature of the overall casting liquid in the casting tank is high, the overall addition speed of the thickener and defoamer can be reduced. When the temperature of the overall casting liquid in the casting tank is low, the overall addition speed of the thickener and defoamer can be increased. The overall addition speed of the thickener and defoamer can be automatically controlled according to the temperature of the overall casting liquid in the casting tank. The movable parts cooperate with the speed control parts and the stirring parts to detect the temperature of the casting liquid at different heights in the casting tank. When the temperature of the local casting liquid in the casting tank is high, the local adding speed of the thickener and the defoamer can be reduced. When the temperature of the local casting liquid in the casting tank is low, the overall adding speed of the thickener and the defoamer can be increased. The overall adding speed of the thickener and the defoamer can be automatically controlled according to the height of the temperature of the local casting liquid in the casting tank. When the temperature of the aluminum alloy casting liquid is high, try to avoid the thickener casting speed being too fast, so that the thickener loses the thickening effect or irreversible viscosity changes under high temperature conditions. Try to avoid the defoamer casting speed being too fast, so that the defoamer is easy to fail and decompose or lose activity at high temperature, which can ensure the effect of the defoamer and thickener on improving the aluminum alloy casting liquid; When the stirring piece is driven, it can drive the connecting piece and the control piece. When the stirring rod rotates, it will also drive the two groups of second blades and the two groups of detection rods to rotate in turn, so as to detect the viscosity of the casting liquid at different heights in the casting tank. When the viscosity of the casting liquid at a local height in the casting tank is large, the resistance encountered by the two detection rods at the corresponding height will be greater. Through the connection and cooperation between the two second blades, the two detection rods, the two connecting blocks, the two telescopic springs and the two supporting rods, the angles of the two detection rods can be adjusted, so that the angles of the two detection rods can be adjusted when affected by the viscosity of the casting liquid. When the two detection rods rotate, they will contact the two feeding blocks. When the swing angle of the detection rod is different, the position of the contact with the fifth wedge block will also be different when it rotates. By specifying the height, the two detection rods rotate and contact the two fifth wedge blocks, so that the two fifth wedge blocks and the two feeding blocks at the specified height can be pushed and translated in turn, and the specified heights can be controlled respectively. The size of the discharge gap between the two feeding blocks at the same height and the two feeding tubes, the more the detection rod pushes the fifth wedge block, and the more the two feeding tubes at the specified height feed the defoamer and the thickener respectively, and the less the two feeding tubes feed the defoamer and the thickener respectively. When the viscosity of the local height of the casting liquid in the casting tank is greater, the less the defoamer and the thickener added to the local height of the casting liquid will be, and when the viscosity of the local height of the casting liquid in the casting tank is smaller, the more the defoamer and the thickener added to the local height of the casting liquid will be. Then, through the cooperation between the two groups of feeding tubes, the two groups of second blades, the two groups of detection rods, the two groups of connecting blocks, the two groups of telescopic springs and the two groups of support rods, the feeding amount of the defoamer and the thickener at the local height can be controlled according to the viscosity of the casting liquid at different heights in the casting tank, and the fluidity and viscosity of the casting liquid at different heights in the casting tank can be avoided as much as possible to ensure the uniform fluidity of the casting liquid in the casting tank.

[0008] Optionally, the stirring member includes a support frame fixed between the tops of the two storage cylinders and a motor fixed on the support frame, and the stirring rod is fixedly connected to the output shaft of the motor.

[0009] By adopting the above technical scheme, the motor can be driven by the stirring member, and then the stirring rod can be driven to rotate by the motor, and then the limit member, the speed regulating member, the movable member and the connecting member can be driven to rotate, so that the defoaming agent and the thickener in the two storage cylinders can be transferred and loaded, and the casting liquid in the casting tank can be stirred, so as to facilitate the uniform mixing of the defoaming agent and the thickener with the casting liquid, thereby ensuring the effect of the defoaming agent and the thickener on the casting liquid and improving the viscosity.

[0010] Optionally, the adjusting member includes a movable push plate fixed on the adjusting plate, and the two adjusting rods are fixedly connected to the movable push plate. The adjusting plate will expand at high temperatures and contract at low temperatures. The adjusting plate can drive the movable push plate to translate due to changes in temperature to control the moving range of the two adjusting rods.

[0011] By adopting the above technical scheme, the temperature of the overall casting liquid in the casting tank can be detected through the adjusting part. When the casting tank is processing the casting liquid, the temperature will be transmitted to the adjusting plate, and then the adjusting plate will expand due to the influence of temperature, so the overall temperature of the casting liquid can be detected. When the adjusting plate expands, it will drive the movable push plate and the two adjusting rods to move in turn. The speed of the speed regulating part can be controlled according to the temperature of the casting liquid in the casting tank. The overall adding speed of the defoaming agent and the thickener can be controlled according to the overall temperature of the casting liquid, thereby ensuring the defoaming and improvement effect of the defoaming agent and the thickener on the casting liquid.

[0012] The transmission gear of the first embodiment is a gearbox, and the transmission gear of the second embodiment is a gearbox, and the gearbox is connected with the transmission gear of the first embodiment to drive the transmission gear of the second embodiment. The two springs are fixedly connected to the stirring rod, and the two first main wheel pieces are slidably connected to the outside of the stirring rod, the two second springs are fixedly connected to the two first main wheel pieces, the two second slave wheel pieces, the two first bevel gears and the two first springs are fixedly connected to the two rotating rods, the two first springs are fixedly connected to the two fixed cone blocks, the two first slave wheel pieces are fixedly connected to the two fixed cone blocks, the two fixed cone blocks are slidably connected to the outsides of the two rotating rods, the two first bevel gears are meshed with the two second bevel gears, and the two second bevel gears are fixed to the outsides of the two feeding spirals, and the two storage barrels are provided with discharge pipes, and the two adjusting rods are movably fitted with the two fixed cone blocks.

[0013] By adopting the above technical solution, the adjusting member can adjust the speed of the speed regulating member, and the two adjusting rods can push the two fixed cone blocks respectively when they move, and cooperate with the elastic force of the two first springs to drive the two fixed cone blocks and the two first slave wheels to move on the two rotating rods respectively, so that the positions of the two conveyor belts between the two first slave wheels and the two second slave wheels can be adjusted respectively. At the same time, when the two conveyor belts are adjusted, the elastic force of the two second springs can also be used to adjust the positions of the two second main wheels respectively, and the positions of the two conveyor belts between the two first main wheels and the two second main wheels can also be adjusted respectively. , the rotation speed of the two rotating rods and the two feeding screws can be adjusted. The greater the expansion of the adjusting plate, the smaller the resistance of the two adjusting rods to the two fixed cone blocks will be. The rotation speed of the two rotating rods and the two feeding screws can be slowed down, and the speed at which the two feeding screws feed the defoamer and the thickener can be slowed down. The smaller the expansion of the adjusting plate, the greater the resistance of the two adjusting rods to the two fixed cone blocks will be. The rotation speed of the two rotating rods and the two feeding screws can be accelerated, and the speed at which the two feeding screws feed the defoamer and the thickener can be accelerated. The overall feeding speed of the defoamer and the thickener can be controlled according to the overall temperature of the casting liquid in the casting tank.

[0014] Optionally, the limiter comprises a stirring blade fixed on the stirring rod, a fixed block hinged on the stirring blade, a compression spring fixed on the fixed block, and a connecting rod fixed on the compression spring, the number of the detection plates is two, the number of the stirring blades, the fixed block, the compression spring and the connecting rod is two groups, the two groups of stirring blades are respectively hinged to the two detection plates, and the two groups of fixed blocks are respectively movably hinged to the two detection plates; The adjusting member includes a connecting spring fixed on the loading plate and a first wedge-shaped block fixed on the loading plate. A loading gap is arranged between the loading plate and the discharge pipe. The discharge pipe, the first wedge-shaped block, the connecting spring and the loading plate are each two in number. Both of the detection plates are movably fitted with the first wedge-shaped block.

[0015] By adopting the above technical scheme, when the stirring piece is driven, it can drive the limit piece and the amount adjusting piece to be driven, and when the stirring rod rotates, it will also drive the two groups of stirring blades and the two detection plates to rotate in turn, so that the overall viscosity of the casting liquid in the casting tank can be detected. When the overall viscosity of the casting liquid in the casting tank is larger, the resistance encountered by the two detection plates will be greater. Through the connection and cooperation between the two groups of stirring blades, the two groups of fixing blocks, the two groups of compression springs, the two groups of connecting rods and the two detection plates, the angles of the two detection plates can be adjusted, and the angles of the two detection plates can be adjusted when affected by the viscosity of the casting liquid. When the two detection plates rotate, they will contact with the two first wedge-shaped blocks, and the swing angles of the detection plates are different when they rotate with the first wedge-shaped blocks. The contact position of a wedge block will also be different, and then the two detection plates will contact the two first wedge blocks when they rotate, and the two first wedge blocks and the two feeding plates can be pushed and translated in turn, and the size of the feeding gap between the two feeding plates and the two discharge pipes can be controlled respectively. The more the detection plate pushes the first wedge block, the more the defoamer and thickener are fed to the two discharge pipes respectively; the less the detection plate pushes the first wedge block, the less the defoamer and thickener are fed to the two discharge pipes respectively; and thus, the greater the overall viscosity of the casting liquid, the less the overall amount of defoamer and thickener added, and the smaller the overall viscosity of the casting liquid in the casting tank, the more the overall amount of defoamer and thickener added.

[0016] Optionally, the speed controlling component includes a third wedge block movably arranged on the casting tank, a third spring fixed on the third wedge block, a fourth wedge block fixed on the third wedge block, a second wedge block fixed on the speed regulating block, an annular spring fixed on the upper agent tube, a limit block fixed on the upper agent tube, a lifting block slidably arranged in the limit block, a first one-way valve fixed on the upper agent tube and a feed pipe fixed on the upper agent tube, the second wedge block and the fourth wedge block are both movably fitted with the lifting block, the annular spring is fixedly connected to the upper agent tube, the third spring is fixedly connected to the casting tank, the feed pipe, the upper agent tube, the speed regulating block, the annular spring, the second wedge block, the third wedge block, the third spring, the fourth wedge block, the lifting block, the limit block and the first one-way valve are all in two groups, and the two groups of feed pipes are respectively connected to the two discharge pipes.

[0017] By adopting the above technical scheme, the adjusting part can adjust the moving speed of the speed control part, and when the two movable rods rotate, they will contact with the two third wedge blocks. The positions of the movable rods moving are different, and the positions of contact with the third wedge blocks when rotating will also be different. Then, by specifying the height, when the two movable rods rotate and contact with the two third wedge blocks, the two fourth wedge blocks can be driven to move, and the two lifting blocks can be driven to slide, and the two second wedge blocks and the two speed regulating blocks can be driven to move, and the defoaming agent and thickener in the two upper agent tubes at the specified height can be pushed respectively, and the feeding speed of the defoaming agent and thickener in the two upper agent tubes at the specified height can be controlled. The more the movable rod pushes the third wedge block, the faster the speed regulating block moves, and the faster the two upper agent tubes at the specified height feed the defoaming agent and the thickener respectively. The fewer positions the wedge block pushes, the slower the speed regulating block moves, and the slower the feeding speed of the two feeding pipes at the specified height for the defoamer and the thickener respectively. As a result, when the temperature of the local height of the casting liquid in the casting tank is higher, the slower the speed of adding the defoamer and the thickener to the local height of the casting liquid; when the temperature of the local height of the casting liquid in the casting tank is lower, the amount of the defoamer and the thickener added to the local height of the casting liquid is faster. Through the cooperation between two groups of heated tubes, two groups of adjusting blocks, two groups of movable blocks, two groups of movable rods, two groups of feeding pipes, two groups of speed regulating blocks, two groups of annular springs, two groups of second wedge blocks, two groups of third wedge blocks, two groups of third springs, two groups of fourth wedge blocks, two groups of lifting blocks and two groups of limit blocks, the feeding speed of the local height of the defoamer and the thickener can be controlled according to the temperature of the casting liquid at different heights in the casting tank.

[0018] Optionally, the movable part includes a heat-receiving tube fixed on the second blade, an adjusting block fixed on the heat-receiving tube, a movable block fixed on the adjusting block, and a movable rod fixed on the movable block. The heat-receiving tube, the adjusting block, the movable block and the movable rod are each in two groups. The two groups of movable rods are movably fitted with two groups of third wedge blocks. The adjusting block will expand at high temperatures and contract at low temperatures. The adjusting block can drive the movable rod to translate due to changes in temperature to control the moving range of the movable rod.

[0019] By adopting the above technical scheme, the movable part can detect the temperature of the local casting liquid in the casting tank. When the casting tank processes the casting liquid, the temperature will be transmitted to the two groups of heat-receiving tubes, and then the adjusting blocks in the two groups of heat-receiving tubes can be expanded respectively due to the influence of temperature. The two groups of adjusting blocks can detect the temperature of the casting liquid at different heights in the casting tank. When the two adjusting blocks at the corresponding heights expand, they will drive the two movable blocks and the two movable rods to move in turn, and the positions of the two movable rods can be adjusted. When the temperature of the casting liquid at a local height in the casting tank is relatively high, the two adjusting blocks at the corresponding heights will respectively drive the two movable rods at the corresponding heights to move into the casting tank. The moving speed of the movable part can be controlled according to the temperature of the specified local casting liquid in the casting tank, and the local addition speed of the defoaming agent and the thickener can be controlled according to the local temperature of the casting liquid, so as to ensure the defoaming and improvement effect of the defoaming agent and the thickener on the casting liquid.

[0020] The second aspect of the present application provides a casting process for aluminum alloy castings using the following technical solution: The present application also discloses a casting process for aluminum alloy castings, based on the above-mentioned casting system for aluminum alloy castings, comprising the following steps: S1. The stirring element can drive the speed regulating element and two feeding screws to rotate, and can deliver the defoamer and thickener in the two storage barrels. The defoamer and thickener in the two storage barrels will be delivered to two groups of feeding pipes and two groups of feeding pipes through two discharge pipes respectively. The two groups of feeding pipes will deliver the defoamer and thickener to different positions in the casting tank respectively, and defoam the casting liquid at different heights in the casting tank and improve the viscosity; S2. The stirring member can drive the limiter, two detection plates, the speed regulating member, the movable member, the connecting member and two sets of detection rods to stir the casting liquid in the casting tank so as to evenly mix the defoamer and the thickener with the casting liquid; S3. When the two detection plates rotate, the overall viscosity of the casting liquid in the casting tank can be detected. The limiter cooperates with the adjusting member and the stirring member. When the overall viscosity of the casting liquid in the casting tank is greater, the overall amount of the defoamer and thickener added is less. When the overall viscosity of the casting liquid in the casting tank is smaller, the overall amount of the defoamer and thickener added is more. The overall amount of the defoamer and thickener added can be controlled according to the overall viscosity of the casting liquid in the casting tank. S4. When the casting tank processes the casting liquid, the temperature will be transmitted to the regulating plate to drive the regulating part and the speed regulating part to adjust the rotation speed of the two feeding screws. When the overall temperature of the casting liquid in the casting tank is higher, the overall adding speed of the defoamer and thickener will be slower. When the overall temperature of the casting liquid in the casting tank is lower, the overall adding speed of the defoamer and thickener will be faster. The overall feeding speed of the defoamer and thickener can be controlled according to the overall temperature of the casting liquid in the casting tank. S5. When the two sets of detection rods rotate, the viscosity of the casting liquid at different heights in the casting tank can be detected. When the viscosity of the casting liquid at a local height in the casting tank is large, the resistance of the two detection rods at the corresponding height will be greater. With the control piece and the connecting piece, the feeding amount of the defoamer and the thickener at the local height can be controlled according to the viscosity of the casting liquid at different heights in the casting tank; S6. When the casting tank processes the casting liquid, the temperature will be transmitted to the two sets of regulating blocks, movable parts and speed control parts, which can push the defoamer and thickener in the two upper agent pipes at the specified height respectively, and can control the feeding speed of the defoamer and thickener in the two upper agent pipes at the specified height. When the temperature of the local height of the casting liquid in the casting tank is higher, the adding speed of the defoamer and thickener to the local height of the casting liquid is slower. When the temperature of the local height of the casting liquid in the casting tank is lower, the adding amount of the defoamer and thickener to the local height of the casting liquid is faster. The feeding speed of the defoamer and thickener at the local height can be controlled according to the temperature of the casting liquid at different heights in the casting tank; S7. After the casting liquid is processed, the casting liquid in the casting tank can be placed into the mold part for shaping processing.

[0021] By adopting the above technical scheme, the addition amount and addition speed of the defoamer and thickener can be controlled according to the viscosity and temperature of the casting liquid in different height directions of the casting tank. There is no need to add the defoamer and thickener from the top of the casting tank. The defoamer and thickener can be added to different height positions of the casting tank to ensure the defoaming and improvement effect of the casting liquid in the casting tank, avoid uneven mixing of the defoamer and thickener with the casting liquid, and prevent the casting liquid at different heights in the casting tank from having different defoaming effects and viscosity improvement effects. The casting quality of the castings is stable, the fluidity is uniform, the defoaming effect is improved, and the dimensional accuracy of the castings is guaranteed.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The connecting pipe can pour the cast aluminum alloy casting liquid into the casting tank, and at the same time, the defoamer and thickener can be poured into the two storage barrels through the two feed pipes. The stirring piece can drive the speed regulating piece and the two feeding screws to rotate, and the defoamer and thickener in the two storage barrels can be transferred. Then, the defoamer and thickener in the two storage barrels will be transferred to the two groups of feed pipes and the two groups of feeding pipes through the two discharge pipes respectively. The two groups of feeding pipes will transfer the defoamer and thickener to different positions inside the casting tank, so that the defoamer and thickener can defoam the casting liquid at different heights in the casting tank. The defoaming agent and thickener are used to remove bubbles and improve viscosity, and try to avoid different defoaming effects and fluidity of the casting liquid at different heights, prevent the casting liquid from having unstable quality, uneven fluidity and poor defoaming effect, so as to ensure the casting quality of the casting liquid. At the same time, the stirring member can drive the limit member, two detection plates, speed regulating member, movable member, connecting member and two groups of detection rods to rotate, and can stir the casting liquid in the casting tank, so as to facilitate the defoaming agent and thickener to be evenly mixed with the casting liquid, so as to ensure the defoaming effect of the defoaming agent and thickener on the casting liquid and improve the viscosity, so as to enhance the defoaming effect of the defoaming agent and thickener on the casting liquid and improve the fluidity; 2. When the two detection plates rotate, the overall viscosity of the casting liquid in the casting tank can be detected. When the overall viscosity of the casting liquid in the casting tank is large, the resistance encountered by the two detection plates is also large. The angles of the two detection plates can be adjusted by the limiter, so that the two detection plates can be adjusted in angle when affected by the viscosity of the casting liquid. Then the limiter cooperates with the adjusting member and the stirring member. When the overall viscosity of the casting liquid in the casting tank is large, the overall amount of the defoamer and thickener added is small. When the overall viscosity of the casting liquid in the casting tank is small, the overall amount of the defoamer and thickener added is large. The overall amount of the defoamer and thickener added can be controlled according to the overall viscosity of the casting liquid in the casting tank. When the viscosity of the aluminum alloy casting liquid is large, the casting of too much thickener causes the fluidity of the casting liquid to be significantly reduced, making it difficult for the casting liquid to flow smoothly during the casting process. Excessive casting of the defoamer causes certain components in the casting liquid to react to form precipitation or colloidal substances. 3. When the casting tank processes the casting liquid, the temperature will be transmitted to the regulating plate, and then the regulating plate will expand due to the influence of temperature, and then the overall temperature of the casting liquid can be detected. When the regulating plate expands, it will drive the regulating part and the speed regulating part to adjust the speed of the two feeding screws. When the overall temperature of the casting liquid in the casting tank is higher, the overall addition speed of the defoamer and the thickener will be slower. When the overall temperature of the casting liquid in the casting tank is lower, the overall addition speed of the defoamer and the thickener will be faster. The overall feeding speed of the defoamer and the thickener can be controlled according to the overall temperature of the casting liquid in the casting tank to avoid the thickener casting speed being too fast when the temperature of the aluminum alloy casting liquid is high, so that the thickener loses its thickening effect under high temperature conditions or undergoes irreversible viscosity changes, resulting in performance degradation. The defoamer casting speed is too fast, so that the defoamer is easy to fail at high temperature, decompose or lose its activity, resulting in its defoaming effect weakened, which can ensure the effect of the defoamer and the thickener on improving the aluminum alloy casting liquid; 4. When the two sets of detection rods rotate, the viscosity of the casting liquid at different heights in the casting tank can be detected. When the viscosity of the casting liquid at a local height in the casting tank is large, the resistance of the two detection rods at the corresponding height will be greater. Then, in combination with the control component and the connecting component, the feeding amount of the defoamer and the thickener at the local height can be controlled according to the viscosity of the casting liquid at different heights in the casting tank, so as to avoid the different fluidity and viscosity of the casting liquid at different heights in the casting tank, so as to ensure the uniform fluidity of the casting liquid in the casting tank; 5. When the casting tank processes the casting liquid, the temperature will be transmitted to the two sets of heating tubes, and then the regulating blocks in the two sets of heating tubes can expand due to the influence of temperature. Then the two sets of regulating blocks can detect the temperature of the casting liquid at different heights in the casting tank. When the two regulating blocks at the corresponding heights expand, they can cooperate with the movable parts and the speed control parts to push the defoaming agent and thickener in the two upper agent tubes at the specified height respectively, and control the feeding speed of the defoaming agent and thickener in the two upper agent tubes at the specified height. When the temperature of the local height of the casting liquid in the casting tank is The higher the temperature, the slower the speed of adding defoamer and thickener to the local height of the casting liquid. When the temperature of the local height of the casting liquid in the casting tank is lower, the faster the defoamer and thickener are added to the local height of the casting liquid. The feeding speed of the defoamer and thickener at the local height can be controlled according to the temperature of the casting liquid at different heights in the casting tank. Try to avoid high casting liquid temperature in the casting tank, which will cause the thickener and defoamer to become ineffective due to too fast adding speed. After the casting liquid is processed, the casting liquid in the casting tank can be placed in the mold for finalizing processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The implementation principle of a casting system for aluminum alloy castings in the embodiment of the present application is as follows: (1) The aluminum alloy casting liquid to be cast can be poured into the inner side of the casting tank 2 through the connecting pipe 56, and the defoaming agent and the thickener can be poured into the two storage cylinders 3 through the two feeding pipes. The motor 5 can sequentially drive the stirring rod 6, the two first main wheel pieces 7, the two second main wheel pieces 8, the two second springs 14, the two conveyor belts 9, the two first slave wheel pieces 10, the two rotating rods 15, the two second slave wheel pieces 11, the two fixed cone blocks 12, the two first springs 13, the two first bevel gears 16, the two second bevel gears 17 and the two feeding screws 37 to rotate. When the two feeding screws 37 rotate, The defoamer and thickener in the two storage barrels 3 are transferred, and then the defoamer and thickener in the two storage barrels 3 are respectively transferred to the two groups of feed pipes 26 and the two groups of upper agent pipes 27 through the two discharge pipes 22. The two groups of upper agent pipes 27 will respectively transfer the defoamer and thickener to different positions inside the casting tank 2, so that the defoamer and thickener can defoam and improve the viscosity of the casting liquid at different heights in the casting tank 2, and try to avoid different defoaming effects and fluidity at different heights of the casting liquid, prevent the casting liquid from having unstable quality, uneven fluidity and poor defoaming effect, so as to ensure the casting quality of the casting liquid; (2) When the stirring rod 6 rotates, it will also drive the two groups of stirring blades 45, the two detection plates 46, the two groups of second blades 50, the two groups of detection rods 51, the two groups of heat receiving tubes 41, the two groups of adjustment blocks 42, the two groups of movable blocks 43 and the two groups of movable rods 44 to rotate in sequence, thereby stirring the casting liquid in the casting tank 2 to ensure the effect of mixing the defoaming agent and the thickener with the casting liquid, so as to enhance the effect of the defoaming agent and the thickener on defoaming and improving the fluidity of the casting liquid; (3) When the two detection plates 46 rotate, the overall viscosity of the casting liquid in the casting tank 2 can be detected. When the overall viscosity of the casting liquid in the casting tank 2 is large, the resistance encountered by the two detection plates 46 is also large, and then the two detection plates 46 will respectively apply pressure to the two groups of connecting rods 49, and then squeeze the two groups of compression springs 48. Then, through the connection and cooperation between the two groups of stirring blades 45, the two groups of fixing blocks 47, the two groups of compression springs 48, the two groups of connecting rods 49 and the two detection plates 46, the angles of the two detection plates 46 can be adjusted. When the two detection plates 46 are affected by the viscosity of the casting liquid, the angles of the two detection plates 46 can be adjusted. When the angle is larger, the pressure on the compression spring 48 is also greater, and then the angle between the detection plate 46 and the stirring blade 45 is also greater, and then the two detection plates 46 will contact the two first wedge blocks 23 when they rotate. The detection plates 46 swing at different angles, and the positions in contact with the first wedge blocks 23 when they rotate will also be different. The larger the angle between the detection plate 46 and the stirring blade 45, the fewer positions the detection plate 46 will contact with the first wedge blocks 23 when it rotates, and the smaller the angle between the detection plate 46 and the stirring blade 45, the more positions the detection plate 46 will contact with the first wedge blocks 23 when it rotates, and then the two detection plates 46 will contact the two first wedge blocks 23 when they rotate. The first wedge blocks 23 are in contact with each other, and then the two first wedge blocks 23 and the two loading plates 25 can be pushed and translated in turn to compress the two connecting springs 24. When the two loading plates 25 are translated, the size of the loading gap between the two loading plates 25 and the two discharge pipes 22 can be controlled respectively. The more the detection plate 46 pushes the first wedge blocks 23, the larger the loading gap between the loading plates 25 and the discharge pipes 22 will be, and then the two discharge pipes 22 will respectively load more defoaming agent and thickener, and the less the detection plate 46 pushes the first wedge blocks 23, the smaller the loading gap between the loading plates 25 and the discharge pipes 22 will be, and then the two discharge pipes 22 will load more defoaming agent and thickener. The feeding amount of the defoamer and thickener respectively to the material pipe 22 is less, and then when the overall viscosity of the casting liquid in the casting tank 2 is greater, the overall amount of the defoamer and thickener added is less, and when the overall viscosity of the casting liquid in the casting tank 2 is smaller, the overall amount of the defoamer and thickener added is more. The overall feeding amount of the defoamer and thickener can be controlled according to the overall viscosity of the casting liquid in the casting tank 2 to avoid excessive thickener casting when the viscosity of the aluminum alloy casting liquid is large, resulting in a significant reduction in the fluidity of the casting liquid, making it difficult for the casting liquid to flow smoothly during the casting process, and excessive defoamer casting causes certain components in the casting liquid to react to form precipitation or colloidal substances; (4) When the casting tank 2 processes the casting liquid, the temperature will be transmitted to the regulating plate 19, and then the regulating plate 19 will expand due to the influence of temperature, and then the overall temperature of the casting liquid can be detected. When the regulating plate 19 expands, it will drive the movable push plate 20 and the two regulating rods 21 to move in turn. When the two regulating rods 21 move, they can push the two fixed cone blocks 12 respectively, and then cooperate with the elastic force of the two first springs 13 to drive the two fixed cone blocks 12 and the two first slave wheels 10 to move on the two rotating rods 15 respectively. When the two first slave wheels 10 move, the positions of the two conveyor belts 9 between the two first slave wheels 10 and the two second slave wheels 11 can be adjusted respectively. At the same time, when the two conveyor belts 9 are adjusted, the elastic force of the two second springs 14 can also be used to adjust the positions of the two second main wheels 8 respectively, and the positions of the two conveyor belts 9 between the two first main wheels 7 and the two second main wheels 8 can also be adjusted respectively. Then, by this method, the rotation speed of the two rotating rods 15 and the two feeding screws 37 can be adjusted; (5) The greater the expansion of the adjustment plate 19, the smaller the resistance of the two adjustment rods 21 to the two fixed cone blocks 12, and the two first springs 13 will gradually move the two fixed cone blocks 12 and the two first follower wheels 10 downward to increase the diameter of the two conveyor belts 9 between the two first follower wheels 10 and the two second follower wheels 11, which can slow down the rotation speed of the two rotating rods 15 and the two feeding screws 37, and slow down the speed of the two feeding screws 37 to feed the defoaming agent and the thickener. The smaller the expansion of the adjustment plate 19, the greater the resistance of the two adjustment rods 21 to the two fixed cone blocks 12, and the two first springs 13 will gradually compress the two fixed cone blocks 12 and the two first follower wheels 10 upward to reduce the diameter of the conveyor belt 9 between the first follower wheels 10 and the second follower wheels 11, which can speed up the two rotating rods 15 and the rotation speed of the two feeding screws 37, the feeding speed of the two feeding screws 37 for the defoamer and the thickener can be accelerated, and then when the overall temperature of the casting liquid in the casting tank 2 is higher, the overall adding speed of the defoamer and the thickener is slower, and when the overall temperature of the casting liquid in the casting tank 2 is lower, the overall adding speed of the defoamer and the thickener is faster. The overall feeding speed of the defoamer and the thickener can be controlled according to the overall temperature of the casting liquid in the casting tank 2, so as to avoid that when the temperature of the aluminum alloy casting liquid is high, the thickener casting speed is too fast, so that the thickener loses its thickening effect under high temperature conditions or undergoes irreversible viscosity changes, resulting in performance degradation, and the defoamer casting speed is too fast, so that the defoamer is easy to fail at high temperature, decompose or lose its activity, resulting in its defoaming effect weakened, so as to ensure the effect of the defoamer and the thickener on improving the aluminum alloy casting liquid; (6) When the two sets of detection rods 51 rotate, the viscosity of the casting liquid at different heights in the casting tank 2 can be detected. When the viscosity of the casting liquid at a local height in the casting tank 2 is relatively large, the resistance encountered by the two detection rods 51 at the corresponding height will be relatively large. The two detection rods 51 will respectively apply pressure to the corresponding two support rods 54, thereby squeezing the two telescopic springs 53. The angles of the two detection rods 51 can be adjusted through the connection and cooperation between the two second blades 50, the two detection rods 51, the two connecting blocks 52, the two telescopic springs 53 and the two support rods 54. The two detection rods 51 can be adjusted in angle when affected by the viscosity of the casting liquid. The greater the angle, the greater the pressure on the telescopic spring 53, and thus the greater the angle between the detection rod 51 and the second blade 50, and thus the greater the angle between the detection rod 51 and the second blade 50, and thus the two detection rods 51 will contact the two loading blocks 38 when they rotate. The detection rod 51 swings at different angles, and the positions in contact with the fifth wedge block 39 when it rotates will also be different. The greater the angle between the detection rod 51 and the second blade 50, the fewer positions in contact with the fifth wedge block 39 when the detection rod 51 rotates, and the smaller the angle between the detection rod 51 and the second blade 50, the more positions in contact with the fifth wedge block 39 when the detection rod 51 rotates. Then, by specifying the height, the two detection rods 51 rotate and contact with the two fifth wedge blocks 39, and the indicated height can be adjusted in sequence. The two fifth wedge blocks 39 and the two loading blocks 38 of a certain height are pushed and translated to compress the two fourth springs 40. When the two loading blocks 38 translate, the size of the discharge gap between the two loading blocks 38 and the two upper agent tubes 27 of the specified height can be respectively controlled. The more the detection rod 51 pushes the fifth wedge block 39, the larger the discharge gap between the loading block 38 and the upper agent tube 27 is, and thus the two upper agent tubes 27 of the specified height respectively feed more defoaming agent and thickener. The less the detection rod 51 pushes the fifth wedge block 39, the smaller the discharge gap between the loading block 38 and the upper agent tube 27 is, and thus the two upper agent tubes 27 respectively feed less defoaming agent and thickener. When the viscosity of the local height of the casting liquid in the casting pot 2 is greater, the amount of the defoamer and thickener added to the local height of the casting liquid is less, and when the viscosity of the local height of the casting liquid in the casting pot 2 is smaller, the amount of the defoamer and thickener added to the local height of the casting liquid is more, and then through the cooperation between the two groups of agent feeding pipes 27, the two groups of second blades 50, the two groups of detection rods 51, the two groups of connecting blocks 52, the two groups of telescopic springs 53 and the two groups of support rods 54, the amount of the defoamer and thickener added to the local height can be controlled according to the viscosity of the casting liquid at different heights in the casting pot 2, and the fluidity and viscosity of the casting liquid at different heights in the casting pot 2 are different as much as possible, so as to ensure the uniform fluidity of the casting liquid in the casting pot 2; (7) When the casting tank 2 processes the casting liquid, the temperature will be transmitted to the two groups of heat-receiving tubes 41, and the regulating blocks 42 in the two groups of heat-receiving tubes 41 will expand due to the influence of the temperature. Then, the two groups of regulating blocks 42 can detect the temperature of the casting liquid at different heights in the casting tank 2. When the two regulating blocks 42 at the corresponding heights expand, they will drive the two movable blocks 43 and the two movable rods 44 to move in turn, and the positions of the two movable rods 44 can be adjusted. When the temperature of the casting liquid at a local height in the casting tank 2 is relatively high, the two regulating blocks 42 at the corresponding heights will drive the two movable rods 44 at the corresponding heights to move into the casting tank 2, and the two movable rods 44 can move when affected by the casting liquid temperature. When the movable rod 44 rotates, it will contact the two third wedge blocks 31. The positions of the movable rod 44 moving are different, and the positions of the movable rod 44 contacting the third wedge block 31 will be different when it rotates. The more the movable rod 44 moves into the casting pot 2, the fewer positions it contacts and pushes with the third wedge block 31. The more the movable rod 44 moves out of the casting pot 2, the more positions it contacts and pushes with the third wedge block 31. Then, by specifying the height, when the two movable rods 44 rotate and contact the two third wedge blocks 31, the two third springs 32 can be compressed, and then the two fourth wedge blocks 33 can be driven to move. When the two fourth wedge blocks 33 move, the two lifting blocks 34 can be driven to slide, and then the two second wedge blocks 30 and the two speed regulating blocks 28 can be driven to move. The two annular springs 29 are squeezed, and when the two speed regulating blocks 28 move, the defoaming agent and the thickener in the two upper agent tubes 27 at the specified height can be pushed respectively, and the feeding speed of the defoaming agent and the thickener in the two upper agent tubes 27 at the specified height can be controlled. The more the movable rod 44 pushes the third wedge block 31, the faster the speed regulating block 28 moves, and the faster the two upper agent tubes 27 at the specified height respectively feed the defoaming agent and the thickener. The fewer the movable rod 44 pushes the third wedge block 31, the slower the speed regulating block 28 moves, and the slower the two upper agent tubes 27 at the specified height respectively feed the defoaming agent and the thickener. When the temperature of the local height of the casting liquid in the casting tank 2 is higher, the defoaming agent and the thickener are fed to the casting tank 2. The lower the temperature of the local height of the casting liquid in the casting tank 2, the faster the defoaming agent and the thickener are added to the local height of the casting liquid. Then, through the cooperation between the two groups of heat pipes 41, the two groups of adjusting blocks 42, the two groups of movable blocks 43, the two groups of movable rods 44, the two groups of agent feeding pipes 27, the two groups of speed regulating blocks 28, the two groups of annular springs 29, the two groups of second wedge blocks 30, the two groups of third wedge blocks 31, the two groups of third springs 32, the two groups of fourth wedge blocks 33, the two groups of lifting blocks 34 and the two groups of limit blocks 35, the feeding speed of the local height of the defoaming agent and the thickener can be controlled according to the temperature of the casting liquid at different height positions in the casting tank 2, so as to avoid the casting liquid temperature in the casting tank 2 being too high.Thickeners and defoamers become ineffective due to too fast addition speed; (8) After the casting liquid is processed, the casting liquid in the casting tank 2 can be placed in the mold part 57 for shaping.

[0040] Embodiment 2:

[0041] The present application also discloses a casting process for aluminum alloy castings, based on the casting system for aluminum alloy castings of the first embodiment, comprising the following steps: S1. The stirring member can drive the speed regulating member and the two feeding screws 37 to rotate, and can deliver the defoamer and thickener in the two storage barrels 3. The defoamer and thickener in the two storage barrels 3 will be delivered to the two groups of feeding pipes 26 and the two groups of feeding pipes 27 through the two discharge pipes 22 respectively. The two groups of feeding pipes 27 will deliver the defoamer and thickener to different positions in the casting tank 2 respectively, and defoam the casting liquid at different heights in the casting tank 2 and improve the viscosity; S2. The stirring member can drive the limit member, two detection plates 46, the speed regulating member, the movable member, the connecting member and two sets of detection rods 51, and the casting liquid in the casting tank 2 can be stirred to facilitate the uniform mixing of the defoaming agent and the thickener with the casting liquid; S3. When the two detection plates 46 rotate, the overall viscosity of the casting liquid in the casting tank 2 can be detected. The limiter cooperates with the adjusting member and the stirring member. When the overall viscosity of the casting liquid in the casting tank 2 is greater, the overall amount of the defoamer and thickener added is less. When the overall viscosity of the casting liquid in the casting tank 2 is smaller, the overall amount of the defoamer and thickener added is more. The overall amount of the defoamer and thickener added can be controlled according to the overall viscosity of the casting liquid in the casting tank 2. S4. When the casting tank 2 processes the casting liquid, the temperature will be transmitted to the regulating plate 19, which will drive the regulating member and the speed regulating member to adjust the rotation speed of the two feeding screws 37. When the overall temperature of the casting liquid in the casting tank 2 is higher, the overall adding speed of the defoamer and the thickener will be slower. When the overall temperature of the casting liquid in the casting tank 2 is lower, the overall adding speed of the defoamer and the thickener will be faster. The overall feeding speed of the defoamer and the thickener can be controlled according to the overall temperature of the casting liquid in the casting tank 2. S5. When the two sets of detection rods 51 rotate, the viscosity of the casting liquid at different heights in the casting tank 2 can be detected. When the viscosity of the casting liquid at a local height in the casting tank 2 is greater, the resistance of the two detection rods 51 at the corresponding height will be greater. With the control part and the connecting part, the feeding amount of the defoamer and the thickener at the local height can be controlled according to the viscosity of the casting liquid at different heights in the casting tank 2; S6. When the casting tank 2 processes the casting liquid, the temperature will be transmitted to the two groups of adjusting blocks 42, which will be movable parts and speed control parts, and the defoaming agent and thickener in the two upper agent tubes 27 at the specified height can be pushed respectively, and the feeding speed of the defoaming agent and thickener in the two upper agent tubes 27 at the specified height can be controlled. When the temperature of the local height of the casting liquid in the casting tank 2 is higher, the adding speed of the defoaming agent and thickener to the local height of the casting liquid is slower. When the temperature of the local height of the casting liquid in the casting tank 2 is lower, the adding amount of the defoaming agent and thickener to the local height of the casting liquid is faster. The feeding speed of the defoaming agent and thickener at the local height can be controlled according to the temperature of the casting liquid at different heights in the casting tank 2; S7. After the casting liquid is processed, the casting liquid in the casting tank 2 can be placed in the mold part 57 for shaping.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
