Description

Technical Field

[0001] The present application relates to the technical field of casting devices, and in particular to a casting device for a lightweight suspension bracket of a component. Background Art

[0002] The lightweight suspension bracket of automobile parts is a general term for the elastic connection device between the frame and the axle. Its function is to connect the axle and the frame, keep the wheels bouncing relative to the body according to a certain movement trajectory, keep the car in a stable posture while driving, and improve handling stability.

[0003] When processing lightweight suspension brackets for automotive parts, a casting device is usually required to cast the bracket. However, bubbles and pores will be generated in the bracket metal liquid during casting. Therefore, a defoaming mechanism is required to defoam the bracket metal liquid. For example, a Chinese patent with publication number CN111745145A in the related art proposes a metal casting device with a defoaming function, which has the function of realizing the linkage of a rotating component and a moving component through a driving source, realizing the rotation of the mold and the movement of the ultrasonic transmitter at the same time, achieving a better defoaming effect. Compared with the existing rotating component, the rotating component can better control the rotation amplitude, avoid the mold rotation amplitude being too large to cause the molten metal to be thrown out, and realize the advantage of protecting the operator.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the current method for defoaming in casting devices is usually to use a rotating mold to achieve the purpose of defoaming the molten metal in the mold. Although this defoaming method is good, it will affect the fluidity and solidification process of the molten metal. The rotating mold will change the flow state of the molten metal in the mold, causing uneven flow of the molten metal and affecting the molding quality of the bracket. At the same time, the centrifugal force generated during the rotation process will also affect the solidification process of the molten metal, resulting in uneven internal structure or defects in the bracket. At the same time, the mold will be subjected to continuous mechanical stress during the rotation process, which will cause the mold to wear more severely and shorten the service life of the mold. Summary of the invention

[0005] In order to solve the problem that the mold will affect the fluidity and solidification process of the molten metal during rotation, the rotating mold will change the flow state of the molten metal in the mold, causing uneven flow of the molten metal and affecting the molding quality of the bracket, the present application provides a casting device for a lightweight suspension bracket for components.

[0006] The present application provides a casting device for a lightweight suspension bracket of a component, which adopts the following technical solution: A casting device for a lightweight suspension bracket of a component, comprising a support frame, a casting mold and a casting box arranged on the support frame, a casting pipe arranged on the casting box, and a decompression box and a medicine feeding pipe arranged on the casting pipe; The pouring box is used for pre-storing the molten metal, and the decompression box is used for storing the decompression agent; The pouring pipe is provided with a control component for controlling the input amount of the molten metal, a decompression component for decompressing the molten metal, and a stirring member for stirring the molten metal; A pushing component for pushing the decompression agent is arranged on the inner side of the decompression box, and an output component for controlling the release amount of the decompression agent is arranged on the inner side of the medicine inlet pipe; The pouring pipe is provided with a detection member for detecting the flow rate of the molten metal; The control assembly includes an adjustment plate movably arranged inside the casting pipe and an adjustment member for adjusting the adjustment plate, the pushing assembly includes a feeding plate movably arranged inside the decompression box and a pushing member for pushing the feeding plate, and a power member for synchronously driving the pushing member and the stirring member is arranged inside the casting pipe; The output component includes a discharge plate movably arranged on the inner side of the medicine feed pipe and a lifting member for lifting the discharge plate; the pressure reducing component includes a pressure reducing plate rotatably arranged on the inner side of the casting pipe and a rotating member for driving the pressure reducing plate to rotate; a driving member for synchronously driving the rotating member and the lifting member is arranged on the inner side of the casting pipe.

[0007] By adopting the above technical scheme, the molten metal that needs to be cast can be stored in the pouring box first, so that the molten metal can be naturally cooled to between one thousand three hundred and sixty and one thousand three hundred and eighty degrees, so as to achieve the purpose of high-temperature molten metal out of the furnace and low-temperature pouring. Because the temperature of the molten metal out of the furnace is usually one thousand five hundred and twenty degrees, the principle of high-temperature out of the furnace and low-temperature pouring can avoid hot cracking and cold cracking of the molten metal due to improper pouring. The molten metal in the pouring box can be placed into the inner side of the casting mold through the pouring pipe, so as to cast the molten metal. The decompression agent can be stored in the decompression box, and the decompression agent can be placed into the inner side of the pouring pipe through the medicine inlet pipe to mix with the molten metal. The molten metal can be optimized, the pores and inclusions can be reduced, the surface tension of the molten metal can be reduced, the fluidity of the molten metal can be improved, and the surface quality of the bracket can be improved, so that the bubbles in the molten metal can be eliminated.

[0008] In the prior art, the method of defoaming the molten metal in the casting mold usually adopts the method of vibrating the mold and knocking the mold to achieve the purpose of eliminating bubbles in the molten metal. Although this defoaming method is convenient, it will damage the mold. When the mold is vibrated, the mold will be subjected to continuous mechanical stress, which will cause fatigue damage to the mold and shorten the service life of the mold. At the same time, it will cause the fasteners inside the mold to loosen, affecting the sealing and precision of the mold. In addition, strong vibration may also cause turbulence in the molten metal, increase the risk of gas entrapment, and aggravate the bubble problem. When the mold is knocked, the mold will be subjected to instantaneous impact force, which will cause local deformation or damage to the mold. Frequent knocking may also cause cracks or fractures in the mold, seriously affecting the service life of the mold and the molding quality of the bracket. The knocking may also disperse the bubbles in the molten metal into smaller bubbles, which are more difficult to completely eliminate, thereby affecting the final quality of the bracket. In addition, the noise and vibration generated during the knocking process may also have an adverse effect on the health of the operator. At the same time, although the optimized casting mold also achieves the purpose of defoaming the molten metal by adding a decompressor or a defoaming agent to the molten metal, most of them achieve the purpose of defoaming the molten metal by adding a decompressor in the mold or the smelting furnace. Although this method can achieve the purpose of defoaming the molten metal, it has certain defects. Adding a decompressor in the mold is not convenient to ensure the uniformity of dispersion and mixing of the decompressor in the molten metal, which will lead to poor local defoaming effect of the molten metal. It is still necessary to shake the mold to achieve uniform mixing of the decompressor and the molten metal. Adding a decompressor in the smelting furnace is not convenient to ensure the amount of the decompressor added, because the volume of the smelting furnace is very large, the amount of molten metal cannot be accurately guaranteed, and the amount of decompressor added needs to be precisely controlled. Too much or too little may affect the defoaming effect or performance of the molten metal. Too much decompressor addition will cause the bubbles in the molten metal to be over-suppressed. Although the bubbles are reduced, it may also affect other physical and chemical properties of the molten metal and affect the performance of the molten metal. Too little decompressor addition cannot effectively suppress the bubbles in the molten metal, resulting in the continued existence of bubbles during the processing, thereby affecting the stability and processing quality of the molten metal.

[0009] The flow rate of the molten metal in the casting pipe can be controlled by the control component. The flow of the molten metal can be controlled according to the type and size of the bracket to be cast in the casting mold to prevent the molten metal from affecting the casting effect of the bracket inside the casting mold due to excessive flow rate. The molten metal in the casting pipe can be decompressed by the decompression component to prevent the molten metal from causing impact damage to the casting mold due to excessive flow rate. At the same time, the molten metal can be prevented from splashing randomly in the casting mold due to the impact force of falling, so as to ensure the casting effect of the casting mold on the molten metal. The molten metal and the decompression agent in the casting pipe can be stirred by the stirring piece to ensure that the molten metal and the decompression agent are fully mixed and the decompression agent can be effective in eliminating bubbles in the molten metal. The decompression agent in the casting box can be pushed by the pushing component to increase the flow rate of the decompression agent inside the casting box. The power piece can pass the molten metal in the casting The flow inside the tube is automatically driven, and the rotation speed of the pushing member and the stirring member can be controlled. When the molten metal flows too fast, the pushing component will push the pressure reducing agent faster. The flow speed of the pressure reducing agent can be controlled according to the flow speed of the molten metal to ensure the effect of the pressure reducing agent on eliminating bubbles in the molten metal. The amount of pressure reducing agent entering the casting tube in the casting box can be controlled by the output component, and the amount of pressure reducing agent fed can be controlled according to the amount of molten metal. The driving member can be automatically driven by the amount pressure of the molten metal on the inside of the casting tube, and then the lifting member and the rotating member can be controlled to drive. When the pressure of the molten metal is too large, the pressure reducing component can decompress the molten metal. At the same time, the pushing component can increase the speed of the pressure reducing agent release. The amount of pressure reducing agent released can be accurately controlled according to the amount of molten metal to ensure the effect of the pressure reducing agent on eliminating bubbles in the molten metal.

[0011] By adopting the above technical solution, the threaded rod can be driven to rotate by the motor, and then the adjusting plate can be driven to move left and right on the inner side of the casting pipe. The distance between the adjusting plate and the casting pipe can be adjusted, and then the flow rate of the molten metal in the casting pipe can be controlled. The flow of the molten metal can be controlled according to the type and size of the bracket to be cast in the casting mold, so as to avoid the molten metal flowing too fast and affecting the casting effect of the bracket inside the casting mold.

[0012] Optionally, the pushing member includes four adjusting rods fixed on the feeding plate, a spiral push plate fixed on the four adjusting rods, a spiral rod rotatably arranged on the decompression box, and a partition plate fixed on the inner side of the decompression box, the spiral push plate is threadedly connected to the spiral rod, and the decompression box is fixedly connected to the casting pipe.

[0013] By adopting the above technical solution, the power part can drive the spiral rod to rotate, which in turn drives the spiral push plate, four adjusting rods and the feeding plate to translate. The feeding plate translates on the inner side of the pressure reducing box, so that the pressure reducing agent in the pressure reducing box can be pushed, so that the pressure reducing agent can quickly enter the inner side of the casting pipe through the medicine feed pipe and mix with the molten metal to achieve the purpose of defoaming the molten metal.

[0014] Optionally, the stirring member includes a stirring rod rotatably disposed in the casting pipe, and movable blade rods are disposed on the outer side of the stirring rod, and the movable blade rods are evenly distributed on the outer side of the stirring rod.

[0015] By adopting the above technical solution, the power component can drive the stirring rod and multiple movable blade rods to rotate in turn, so that the molten metal can be stirred during the falling process, so as to fully mix the molten metal and the pressure reducing agent, thereby enhancing the defoaming effect of the pressure reducing agent on the molten metal.

[0016] Optionally, the power component includes a power rod, a water blade, a manual turning handle, a first gear, a second gear, a driving wheel, a transmission belt and a driven wheel rotatably arranged on the casting pipe, and a movable rod, a first bevel gear and a second bevel gear rotatably arranged on the pressure reducing box, the first bevel gear is meshed with the second bevel gear, the first gear is meshed with the second gear, the water blades are evenly distributed on the outside of the power rod, a plurality of the water blades, the first gear, the driving wheel and the manual turning handle are all arranged on the outside of the power rod, the second bevel gear is fixedly connected to the spiral rod, the first bevel gear and the driven wheel are both provided with the outside of the movable rod, the driven wheel and the driving wheel are both connected to the transmission belt, and the second gear is fixedly connected to the stirring rod.

[0017] By adopting the above technical scheme, the molten metal will flow onto the water blades. Through the weight of the falling molten metal, it will sequentially drive multiple water blades, the power rod, the manual handle, the first gear, the driving wheel, the transmission belt, the driven wheel, the movable rod, the first bevel gear, the second bevel gear, the screw rod and the second gear to rotate, thereby driving the screw rod and the stirring rod to rotate synchronously, thereby achieving the purpose of synchronously driving the pusher and the stirring member. At the same time, the pusher and the stirring member can also be driven by rotating the manual handle.

[0018] Optionally, the lifting member includes a movable cone block fixed on a discharge plate, four telescopic springs fixed on the movable cone block, and a movable push block rotatably arranged on the casting pipe. The bottom of the movable cone block is an inclined surface, and the movable push block is movably fitted with the inclined surface of the movable cone block. The four telescopic springs are fixedly connected to the medicine feed pipe. A connecting square hole is provided at the bottom of the medicine feed pipe. The discharge plate is slidably connected to the connecting square hole, and the casting pipe and the pressure reducing box are both connected to the medicine feed pipe.

[0019] By adopting the above technical scheme, the driving member can push the movable cone block to move horizontally, which will gradually relax the four telescopic springs, and then drive the discharge plate and the movable cone block to move downward in turn, so that the distance between the movable cone block and the medicine feed pipe becomes larger, thereby increasing the release amount of the decompression agent. At the same time, when the pressure of the molten metal is too low, the molten metal cannot push the movable push block to move significantly through the pressure of the annular spring, and then the elastic force of the four telescopic springs can reduce the distance between the movable cone block and the medicine feed pipe. Therefore, when the amount of molten metal is too small, the opening of the medicine feed pipe can be narrowed to reduce the release amount of the decompression agent. The amount of decompression agent released can be controlled according to the amount of molten metal flowing to enhance the effect of the decompression agent on eliminating bubbles in the molten metal and prevent the decompression agent from being added too much or too little to affect the defoaming effect of the molten metal or the performance of the molten metal.

[0020] Optionally, the rotating member includes a support rod rotatably arranged on the casting pipe, and the number of the pressure relief plates is two, and the two pressure relief plates are symmetrically arranged on the outside of the support rod, and the two pressure relief plates are both arranged on the outside of the support rod.

[0021] By adopting the above technical scheme, the driving member can drive the support rod and the two pressure relief plates to rotate in turn, and the molten metal can be decompressed during the rotation of the two pressure relief plates, which can have a certain buffering effect when the molten metal falls, thereby preventing the casting mold from being damaged by stamping due to excessive pressure during the falling process of the molten metal. At the same time, it can prevent the molten metal from splashing randomly in the casting mold due to the impact force of the fall, so as to ensure the casting effect of the casting mold on the molten metal.

[0022] Optionally, the driving member includes a connecting rod, a power plate, a trapezoidal cone block, an annular spring, a third gear and a fourth gear rotatably arranged on the casting pipe, the third gear is movably engaged with the fourth gear, the power plate is evenly distributed on the outside of the connecting rod, a plurality of the power plates, movable push blocks, third gears, annular springs and trapezoidal cone blocks are all arranged on the outside of the connecting rod, the fourth gear is arranged on the outside of the support rod, a circular groove is opened on the outside of the casting pipe, and one end of the annular spring is slidably connected to the inner side of the circular groove.

[0023] By adopting the above technical scheme, the molten metal will flow onto the power plate when it flows downward, and the weight of the falling molten metal will drive multiple power plates, connecting rods, trapezoidal cone blocks, annular springs, movable push blocks and the third gear to rotate in turn. When the amount of molten metal falling is too much and the pressure is too great, the pressure of the falling molten metal will push the trapezoidal cone block, connecting rod, multiple power plates, movable push blocks and the third gear to rotate and move in turn. At this time, the annular spring is in a compressed state, so that the third gear is meshed with the fourth gear, so that when the third gear rotates, it will drive the fourth gear and the support rod in turn. At the same time, the movable push block will also drive the movable cone block to translate upward when pushing, and then drive the support rod and the movable cone block to drive synchronously, so as to achieve the purpose of synchronous driving of the rotating part and the lifting part.

[0024] Optionally, the detection component includes a movable block and a rubber block rotatably set on the casting pipe, a counter fixed on the casting pipe, a scale fixed on the fixed frame, and a pointer fixed on the adjustment plate, the pointer is slidingly connected to the scale, the rubber block is movably fitted with the counter, and the rubber block and the power rod are fixedly connected to the movable block.

[0025] By adopting the above technical scheme, the power rod will also drive the movable block and the rubber block to rotate in turn during its rotation. The rubber block will hit the counter during its rotation, and then the counter can count. The counter counts once every time the rubber block rotates one circle. Therefore, the rotation speed of the power rod and the water blade can be inferred by the count of the counter. The adjustment plate will also drive the pointer to move on the scale during its movement. When the pointer points to the scale of the specified scale, the rotation of the power rod and the water blade can be roughly inferred by the distance between the adjustment plate and the casting pipe. The counter can be used for reminder. When the count per minute of the counter does not match the scale on the scale, it may indicate that the distance between the adjustment plate and the casting pipe is reduced due to the adhesion of dirt due to the addition of the pressure reducing agent. Then, the distance between the adjustment plate and the casting pipe can be temporarily expanded by the motor, so that the distance between the adjustment plate and the casting pipe is maintained at the optimal distance according to the type and size of the bracket to be cast, so as to ensure that the flow of the molten metal is equal to the outflow of the pressure reducing agent, thereby enhancing the defoaming effect of the pressure reducing agent on the molten metal.

[0026] Optionally, the casting mold includes an upper mold and a lower mold, the upper mold is movably fitted with the lower mold, and the casting mold is provided with a clamping member for fixing the lower mold and the upper mold, the clamping member includes two movable screws rotatably arranged on the casting mold, two movable turning handles and two positioning blocks, and two fixed screw racks fixed on the lower mold, two positioning grooves are provided on the outer side of the upper mold, the two positioning blocks are movably engaged with the two positioning grooves, the two movable screws are respectively threadedly connected with the two fixed screw racks, and the two movable turning handles and the two positioning blocks are respectively fixedly connected with the two movable screws.

[0027] By adopting the above technical scheme, the two movable rotating handles can respectively drive the two movable screws and the two positioning blocks to rotate and move, so that the two positioning blocks are respectively separated from the two positioning grooves on the upper mold, so that the upper mold loses its limit, so that the upper mold can be moved, and the cast bracket can be taken out. At the same time, through the cooperation between the two fixed screw frames, the two movable screws, the two movable rotating handles, the two positioning blocks and the two positioning grooves, the upper mold and the lower mold can be stably connected together, avoiding the phenomenon of the upper mold and the lower mold being offset during the pouring of the molten metal, so as to ensure the casting effect of the bracket.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The pouring box can store the molten metal for natural cooling, so that the molten metal can be discharged from the furnace at high temperature and poured at low temperature, which can avoid hot cracking and cold cracking of the molten metal due to improper pouring. The decompression agent is poured into the inner side of the decompression box, and then the decompression agent enters the inner side of the pouring pipe through the drug inlet pipe and mixes with the molten metal, which can optimize the molten metal, reduce pores and inclusions, reduce the surface tension of the molten metal, improve the fluidity of the molten metal, and thus improve the surface quality of the bracket, and then eliminate the bubbles in the molten metal; 2. The motor can drive the threaded rod to rotate, which in turn drives the adjustment plate to move left and right inside the casting pipe. The distance between the adjustment plate and the casting pipe can be adjusted to control the flow rate of the molten metal in the casting pipe. The flow of the molten metal can be controlled according to the type and size of the bracket to be cast in the casting mold to avoid the molten metal from affecting the casting effect of the bracket inside the casting mold due to excessive flow rate; 3. The molten metal mixed with the pressure reducing agent will flow downward through the gap between the adjusting plate and the casting pipe, and the molten metal will flow onto the water blades. The weight of the molten metal as it falls will drive multiple water blades, power rods, manual handles, the first gear, the driving wheel, the transmission belt, the driven wheel, the movable rod, the first bevel gear, the second bevel gear and the spiral rod to rotate in sequence, and then drive the spiral push plate, the four adjusting rods and the feeding plate to translate in sequence, which can push the pressure reducing agent in the pressure reducing box so that the pressure reducing agent can quickly enter the inner side of the casting pipe through the medicine feeding pipe to mix with the molten metal. When the molten metal falls very fast, due to the flow rate The reason is that multiple water blades will rotate very fast, which will drive the feeding plate to move quickly inside the pressure reducing box, speeding up the feeding plate to push the pressure reducing agent. When the metal liquid falls too fast, the speed of the pressure reducing agent discharging will also increase. When the metal liquid falls too slowly, the speed of the pressure reducing agent discharging will also slow down. The flow speed of the pressure reducing agent can be controlled according to the flow speed of the metal liquid to ensure the effect of the pressure reducing agent on eliminating bubbles in the metal liquid, to avoid the metal liquid flowing too fast and causing the pressure reducing agent to be fully mixed, and to avoid the metal liquid flowing too slowly and causing a large amount of pressure reducing agent to be mixed, so as to ensure the effect of the pressure reducing agent addition; 4. The first gear is meshed with the second gear, so the first gear rotates, which in turn drives the second gear, the stirring rod and the multiple movable blade rods to rotate, so that the molten metal can be stirred in the process of falling, so as to fully mix the molten metal with the decompressor, thereby enhancing the defoaming effect of the decompressor on the molten metal; 5. When the molten metal flows downward through the gap between the adjusting plate and the pouring pipe, the molten metal will also flow onto the power sheet. The weight of the molten metal when it falls will drive multiple power sheets, connecting rods, trapezoidal cone blocks, annular springs, movable push blocks and the third gear to rotate in turn. When the amount of molten metal falling is too much and the pressure is too high, the pressure of the molten metal when it falls will push the trapezoidal cone block, connecting rods, multiple power sheets, movable push blocks and the third gear to rotate and move in turn. At this time, the annular spring is in a compressed state, so that the third gear is meshed with the fourth gear. Therefore, when the third gear rotates, it will drive the fourth gear, the support rod and the two pressure relief plates to rotate in turn. Then, the molten metal can be decompressed during the rotation of the two pressure relief plates, which can have a certain buffering effect when the molten metal falls, so as to avoid the casting mold being damaged by stamping due to excessive pressure during the falling process of the molten metal. At the same time, it can prevent the molten metal from splashing randomly in the casting mold due to the impact force of the fall, so as to ensure the casting effect of the casting mold on the molten metal. 6. At the same time, when the movable push block gradually translates on the movable cone block due to pressure, the four telescopic springs will gradually relax, and then the discharge plate and the movable cone block will be driven downward in turn, so that the distance between the movable cone block and the medicine feed pipe becomes larger, thereby increasing the release of the pressure reducing agent. Therefore, when the amount of molten metal is too much, the opening of the medicine feed pipe can be increased to speed up the release of the pressure reducing agent. At the same time, when the pressure of the molten metal is too low, the molten metal cannot push the movable push block to move significantly through the pressure of the annular spring, and then the elastic force of the four telescopic springs can make the distance between the movable cone block and the medicine feed pipe The spacing between the two becomes smaller, thereby reducing the amount of pressure reducing agent released. Therefore, when the amount of molten metal is too small, the opening of the medicine inlet pipe can be reduced to reduce the amount of pressure reducing agent released. The amount of pressure reducing agent released can be controlled according to the amount of molten metal flowing to enhance the effect of the pressure reducing agent on eliminating bubbles in the molten metal, and avoid the situation where the bubbles in the molten metal are not completely eliminated due to the large amount of molten metal and the small amount of pressure reducing agent. At the same time, it can also avoid the situation where the performance of the molten metal is affected due to the small amount of molten metal and the large amount of pressure reducing agent. The amount of pressure reducing agent flowing can be controlled according to the amount of molten metal flowing, which can further enhance the effect of the pressure reducing agent on eliminating bubbles in the molten metal. The decompression agent has an effect on eliminating bubbles in the molten metal, and the effect of adding the decompression agent is enhanced to prevent the decompression agent from being added too much or too little to affect the defoaming effect of the molten metal or the performance of the molten metal. The defoamed molten metal in the pouring pipe will be placed into the inner side of the casting mold through the telescopic pipe to complete the pouring of the molten metal and achieve the purpose of bracket casting. The overall structure is simple and easy to use, and the purpose of good defoaming effect of the molten metal is achieved. There is no need to add a decompression agent in the mold or the smelting furnace to achieve the purpose of defoaming the molten metal. The dispersion and mixing uniformity of the decompression agent in the molten metal can be guaranteed, and the local defoaming of the molten metal is enhanced. The effect is that there is no need to shake the mold to achieve uniform mixing of the pressure reducing agent and the molten metal, the amount of pressure reducing agent added can be guaranteed, the amount of molten metal can be accurately guaranteed, and the amount of pressure reducing agent added can be accurately controlled to ensure the defoaming effect of the molten metal and the performance of the molten metal, avoid excessive suppression of bubbles in the molten metal due to excessive addition of pressure reducing agent, avoid affecting other physical and chemical properties of the molten metal and affecting the performance of the molten metal, prevent too little pressure reducing agent from being added to effectively suppress bubbles in the molten metal, prevent bubbles from continuing to exist during the processing, and ensure the stability of the molten metal and the processing quality.

[0043] A temperature display 50 is fixedly connected to the outside of the pouring box 4, and a temperature sensor is arranged on the temperature display 50. The temperature sensor is located on the inside of the pouring box 4. A liquid inlet pipe is fixedly connected to the top of the pouring box 4, and a movable cover is movably connected to the top of the liquid inlet pipe. By arranging the temperature display 50 and the temperature sensor, the temperature of the molten metal inside the pouring box 4 can be detected, and by arranging the solenoid valve 51, the timing opening or closing of the bottom of the pouring box 4 can be controlled.

[0044] The implementation principle of a casting device for a lightweight suspension bracket of a component in the embodiment of the present application is as follows: (1) The movable cover can be opened to pour the molten metal of the bracket to be cast into the inner side of the casting box 4. The casting box 4 can store the molten metal first so that the molten metal can be naturally cooled to between 1,360 and 1,380 degrees, so as to achieve the purpose of high-temperature furnace discharge and low-temperature casting of the molten metal. The principle of high-temperature furnace discharge and low-temperature casting can avoid hot cracking and cold cracking of the molten metal due to improper casting. The temperature of the molten metal can be monitored by the temperature display 50 and the temperature sensor. When the temperature of the molten metal drops to a specified range, the casting pipe 3 can be opened by the solenoid valve 51 to achieve the purpose of molten metal casting; (2) The sealing cover can be opened to pour the pressure reducing agent into the inner side of the pressure reducing box 5 and then the sealing cover can be closed. Then, the pressure reducing agent will enter the inner side of the casting tube 3 through the drug inlet pipe 6 and mix with the molten metal, which can optimize the molten metal, reduce pores and inclusions, reduce the surface tension of the molten metal, improve the fluidity of the molten metal, and thus improve the surface quality of the bracket, thereby eliminating bubbles in the molten metal; (3) The threaded rod 9 can be driven to rotate by the motor 8. Since the threaded rod 9 is threadedly connected to the adjusting plate 10, the adjusting plate 10 can be driven to move left and right inside the casting tube 3 during the rotation of the threaded rod 9. During the movement of the adjusting plate 10 left and right, the distance between the adjusting plate 10 and the casting tube 3 can be adjusted, thereby controlling the flow rate of the molten metal in the casting tube 3. The flow of the molten metal can be controlled according to the type and size of the bracket to be cast in the casting mold 2, thereby preventing the molten metal from affecting the casting effect of the bracket inside the casting mold 2 due to excessive flow rate; (4) Then, the molten metal mixed with the pressure reducing agent will flow downward through the gap between the adjusting plate 10 and the pouring pipe 3, and the molten metal will fall on the water blades 12. The weight of the molten metal when falling will drive the multiple water blades 12, the power rod 11, the manual handle 40, the first gear 13 and the driving wheel 14 to rotate in sequence. Because the driving wheel 14 and the driven wheel 16 are both connected to the transmission belt 15, the driving wheel 14 will drive the transmission belt 15, the driven wheel 16, the movable rod 17 and the first bevel gear 18 to rotate in sequence during the rotation of the driving wheel 14. The first bevel gear 18 is meshed with the second bevel gear 19, so the first bevel gear 18 rotates, which in turn drives the second bevel gear 19 and the screw rod 20 to rotate. Since the screw rod 20 is threadedly connected with the screw push plate 21, the screw push plate 21, the four adjustment rods 22 and the feed plate 24 are translated in turn during the rotation of the screw rod 20. The decompression agent in the decompression box 5 can be pushed by the translation of the feed plate 24 inside the decompression box 5, so that the decompression agent can quickly enter the inner side of the casting tube 3 through the drug inlet pipe 6 to mix with the molten metal. (5) When the molten metal falls very fast, the multiple water blades 12 will also rotate very fast due to the flow rate. Then, due to the connection and transmission effect of the structure between the power parts, the feed plate 24 will be driven to move quickly inside the pressure reducing box 5, thereby accelerating the speed of the feed plate 24 pushing the pressure reducing agent. When the molten metal falls too fast, the speed of the pressure reducing agent discharging will also increase. When the molten metal falls too slowly, the speed of the pressure reducing agent discharging will also slow down. The flow rate of the pressure reducing agent can be controlled according to the flow rate of the molten metal to ensure the effect of the pressure reducing agent on eliminating bubbles in the molten metal, to avoid the molten metal flowing too fast and causing the pressure reducing agent to be insufficiently mixed, and to avoid the molten metal flowing too slowly and causing the pressure reducing agent to be mixed in large quantities, thereby ensuring the effect of the pressure reducing agent addition. (6) Because the first gear 13 is meshed with the second gear 25, the first gear 13 rotates, which in turn drives the second gear 25, the stirring rod 26 and the plurality of movable leaf rods 27 to rotate. The plurality of movable leaf rods 27 rotate, which can stir the molten metal in the process of falling, so as to fully mix the molten metal with the decompressing agent, thereby enhancing the defoaming effect of the decompressing agent on the molten metal. (7) When the molten metal flows downward through the gap between the adjusting plate 10 and the pouring pipe 3, the molten metal will also flow onto the power sheet 29. The weight of the molten metal when it falls will also drive the multiple power sheets 29, the connecting rod 28, the trapezoidal cone block 30, the annular spring 31, the movable push block 32 and the third gear 33 to rotate in sequence. When the amount of molten metal falling is too much and the pressure is too large, the pressure of the molten metal when it falls will push the trapezoidal cone block 30, the connecting rod 28, the multiple power sheets 29, the movable push block 32 and the third gear 33 to rotate and move in sequence. At this time, the annular spring 31 is in a compressed state, so that the third gear 33 is meshed with the fourth gear 34, so that when the third gear 33 rotates, it will drive the fourth gear 34, the support rod 35 and the two pressure relief plates 36 to rotate in sequence, and then the two pressure relief plates 36 can reduce the pressure on the molten metal during the rotation process, which can have a certain buffering effect when the molten metal falls, so as to prevent the casting mold 2 from being damaged by the stamping due to the excessive pressure of the falling molten metal during the falling process, and at the same time, it can prevent the molten metal from randomly splashing in the casting mold 2 due to the impact force of the falling, so as to ensure the casting effect of the casting mold 2 on the molten metal; (8) At the same time, when the movable push block 32 gradually translates on the movable cone block 39 due to pressure, the four telescopic springs 38 are gradually in a relaxed state, and then the discharge plate 37 and the movable cone block 39 are driven to move downward in turn, so that the distance between the movable cone block 39 and the medicine feed pipe 6 becomes larger, thereby increasing the release amount of the decompressing agent. Therefore, when the amount of molten metal is too much, the opening of the medicine feed pipe 6 can be increased through the connecting transmission effect of the structure between the driving parts to accelerate the release amount of the decompressing agent. At the same time, when the pressure of the molten metal is too low, the molten metal cannot push the movable push block 32 to move significantly through the pressure of the annular spring 31, and then the elastic force of the four telescopic springs 38 can reduce the distance between the movable cone block 39 and the medicine feed pipe 6, thereby increasing the release amount of the decompressing agent. The amount of pressure reducing agent released can be reduced. Therefore, when the amount of molten metal is too small, the opening of the medicine inlet pipe 6 can be reduced to reduce the amount of pressure reducing agent released. The amount of pressure reducing agent released can be controlled according to the amount of molten metal flowing to enhance the effect of the pressure reducing agent on eliminating bubbles in the molten metal, and avoid the situation that the bubbles in the molten metal are not completely eliminated due to the excessive amount of molten metal and the insufficient amount of pressure reducing agent. At the same time, it can also avoid the situation that the performance of the molten metal is affected due to the excessive amount of molten metal and the excessive amount of pressure reducing agent. The amount of pressure reducing agent flowing can be controlled according to the amount of molten metal flowing, and the effect of the pressure reducing agent on eliminating bubbles in the molten metal can be further enhanced, and the effect of the pressure reducing agent addition can be enhanced to prevent the defoaming effect or the performance of the molten metal from being affected by excessive or insufficient addition of the pressure reducing agent. (9) The defoamed molten metal in the pouring tube 3 is placed into the inner side of the casting mold 2 through the telescopic tube 52 to complete the pouring of the molten metal and achieve the purpose of bracket casting; (10) After the bracket is cast, the two movable handles 43 are rotated to drive the two movable screws 42 and the two positioning blocks 44 to rotate. Because the two movable screws 42 are respectively threadedly connected to the two fixed screw frames 41, the two movable screws 42 are rotated to drive the two positioning blocks 44 to rotate and move, so that the two positioning blocks 44 are separated from the two positioning grooves on the upper mold, so that the upper mold loses its limit position. The upper mold can be moved by grabbing the two fixed handles, so that the cast bracket can be taken out. (11) At the same time, through the above principle, the upper mold and the lower mold can be stably connected together through the cooperation between the two fixed screw frames 41, the two movable screw rods 42, the two movable handles 43, the two positioning blocks 44 and the two positioning grooves, so as to avoid the deviation of the upper mold and the lower mold during the pouring of the molten metal, so as to ensure the casting effect of the bracket; (12) During the rotation of the power rod 11, the movable block 45 and the rubber block 46 are driven to rotate in turn. During the rotation of the rubber block 46, the counter 47 is hit, and the counter 47 can count. Each time the rubber block 46 rotates one circle, the counter 47 counts once. Therefore, the rotation speed of the power rod 11 and the water blade 12 can be inferred through the count of the counter 47. During the movement of the adjustment plate 10, the pointer 49 is also driven to move on the scale 48. When the pointer 49 points to the designated scale of the scale 48, the rotation of the power rod 11 and the water blade 12 can be roughly inferred through the distance between the adjustment plate 10 and the casting pipe 3. The counter 47 can be used to remind. When the counts per minute of the counter 47 do not match the scale on the scale 48, it may indicate that the distance between the adjustment plate 10 and the pouring pipe 3 is reduced due to dirt adhesion caused by the addition of the pressure reducing agent, and then the distance between the adjustment plate 10 and the pouring pipe 3 can be temporarily expanded by the motor 8, so that the distance between the adjustment plate 10 and the pouring pipe 3 is maintained at the optimal distance according to the type and size of the bracket to be cast, so as to ensure that the flow of the molten metal is kept equal to the outflow of the pressure reducing agent, and enhance the defoaming effect of the pressure reducing agent on the molten metal. After the molten metal is poured, the dirt adhered to the inside of the pouring pipe 3 and the medicine feeding pipe 6 can be cleaned by removing the two sealing plates to ensure the effect of the subsequent addition of the pressure reducing agent; (13) When the bracket is cast, by rotating the manual handle 40, the power rod 11, the driving wheel 14, the transmission belt 15, the driven wheel 16, the movable rod 17, the first bevel gear 18, the second bevel gear 19 and the screw rod 20 can be rotated in sequence, and then the screw push plate 21, the four adjustment rods 22 and the feed plate 24 can be translated in sequence, and the feed plate 24 can be moved to the bottom position where it fits with the partition plate 23, so that the decompression agent can be continued to be added to the inner side of the decompression box 5, so as to facilitate the casting process of the next bracket.

[0045] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of good metal liquid defoaming effect is achieved. There is no need to use the method of vibrating the mold, knocking the mold and rotating the mold to achieve the purpose of eliminating bubbles in the metal liquid, avoiding fatigue damage to the mold, and improving the service life of the mold. It avoids loosening of fasteners inside the mold, ensures the sealing and precision of the mold, and prevents the mold from causing turbulence in the metal liquid due to strong vibration, so as to reduce the risk of gas entrapment, reduce the probability of bubble aggravation, avoid local deformation or damage to the mold due to impact force, prevent frequent knocking from causing cracks or fractures in the mold, and enhance the service life of the mold and the molding quality of the bracket. Small bubbles can be completely eliminated to ensure the final quality of the bracket, avoid adverse effects of noise and vibration on the health of operators, and ensure the fluidity and solidification process of the metal liquid; There is no need to add a pressure reducing agent in the mold or the smelting furnace to achieve the purpose of defoaming the molten metal. The dispersion and mixing uniformity of the pressure reducing agent in the molten metal can be guaranteed, and the local defoaming effect of the molten metal can be enhanced. There is no need to shake the mold to achieve uniform mixing of the pressure reducing agent and the molten metal. The amount of the pressure reducing agent added can be guaranteed, and the amount of the molten metal can be accurately guaranteed. The amount of the pressure reducing agent added can be accurately controlled to ensure the defoaming effect of the molten metal and the performance of the molten metal, avoid excessive suppression of bubbles in the molten metal due to excessive addition of the pressure reducing agent, avoid affecting other physical and chemical properties of the molten metal, affect the performance of the molten metal, prevent the pressure reducing agent from being added too little to effectively suppress the bubbles in the molten metal, prevent the bubbles from continuing to exist during the processing, and ensure the stability of the molten metal and the processing quality.
