Description

Technical Field

[0001] This application relates to the technical field of casting apparatus, and in particular to a casting apparatus for a lightweight suspension bracket. Background Technology

[0002] The suspension bracket is mainly made of materials such as aluminum-silicon alloy, aluminum-magnesium alloy and aluminum-copper alloy. When the molten metal of the suspension bracket is cast, micro bubbles are easily formed, which weakens the fatigue strength and reliability of the casting. At the same time, in order to obtain a fine internal grain structure, the casting process strictly follows the core principles of "high temperature tapping" to ensure fluidity and "low temperature casting" to suppress crystal coarsening.

[0003] Existing technologies require drastically different casting equipment for supports made of different materials due to their varying alloy properties and application scenarios. In the defoaming process, specialized defoamers are needed for different alloy molten metals: organosilicon defoamers are added for aluminum-silicon alloys, alcohol-based defoamers for aluminum-magnesium alloys, and polyether defoamers for aluminum-copper alloys. Regarding low-temperature casting control, the cooling time must be controlled according to the difficulty of cooling different alloy molten metals: aluminum-silicon molten metals require slow cooling, aluminum-magnesium molten metals require stable cooling, and aluminum-copper molten metals require faster cooling.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Firstly, configuring independent dedicated casting devices for different alloy supports such as aluminum-silicon, aluminum-magnesium, and aluminum-copper will lead to a significant increase in equipment investment and floor space, and the production line switching efficiency will be low. In actual production, the market demand for different alloy products fluctuates, and independent dedicated lines will inevitably result in some production lines operating at full capacity while others are idle, causing huge fixed asset idleness and capacity waste. When orders involve small batches and multiple varieties of various alloys, it is impossible to flexibly schedule equipment according to demand priority, resulting in extended delivery time and loss of market competitiveness. Therefore, improvements are proposed to address these issues. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a casting device for a lightweight suspension bracket.

[0006] The casting device for a lightweight suspension bracket provided in this application adopts the following technical solution: A casting device for a lightweight suspension bracket includes a casting frame, a temperature control box fixed on the casting frame, a video sensor for detecting molten metal, and a defoaming component, a cooling component, and a mold component for defoaming, cooling, and casting the molten metal. The cooling assembly includes a casting pipe fixed in a temperature control box, a first connecting pipe, a second connecting pipe and a three-way connecting pipe, a cooling component for cooling the molten metal, a switching component for switching the molten metal transport route, and a regulating component for adjusting the flow rate of the molten metal. The defoaming assembly includes a defoaming tank rotatably mounted on a temperature control box, three defoaming chambers disposed within the defoaming tank, defoaming pipes respectively connected to the three defoaming chambers, a feed pipe connected to a casting pipe, a driving component for driving the three defoaming pipes to connect to the feed pipe one by one, a control component for controlling the amount of defoamer added in the feed pipe, an opening and closing component for automatically opening and closing the three defoaming pipes, and a synchronizing component for synchronously adjusting the switching component, the adjusting component, the driving component, and the opening and closing component. The three defoaming chambers are a polyether defoaming chamber, an alcohol defoaming chamber, and an organosilicon defoaming chamber.

[0007] By adopting the above technical solution, the molten metal is tapped at high temperature and then cast at low temperature, which can avoid thermal cracking and cold cracking caused by improper pouring. In the existing technology, after the molten metal is tapped at high temperature, natural cooling or a single refrigeration method is usually used to cool the molten metal to the required temperature to achieve the purpose of low-temperature casting. This method is not only time-consuming and labor-intensive, but also affects the efficiency of casting. Moreover, the contact time between the molten metal and air during cooling is prolonged, which intensifies the oxidation reaction and affects the quality of casting. In addition, the cooling rate of different molten metals is different. While existing casting molds also employ defoamers to defoam the molten metal, most methods involve adding the defoamer inside the mold or in the smelting furnace. While this method achieves defoaming, it has several drawbacks. Adding the defoamer inside the mold makes it difficult to ensure uniform dispersion and mixing in the molten metal, leading to poor localized defoaming. Shaking the mold is still necessary to achieve even mixing. Adding the defoamer in the smelting furnace presents challenges in controlling the dosage due to the furnace's large volume and the inability to precisely control the molten metal volume. Too much or too little defoamer can negatively impact the defoaming effect or the metal's performance. Excessive defoamer suppression can affect other physical and chemical properties of the molten metal, impacting its performance. Insufficient defoamer fails to effectively suppress bubbles, causing them to persist during processing, thus affecting the stability and quality of the molten metal. By setting up polyether defoaming chambers, alcohol defoaming chambers, and silicone defoaming agent chambers within the defoaming tank, polyether defoamers, alcohol defoamers, and silicone defoamers can be stored separately. The defoamers can be added to the casting pipe through the defoaming pipe and feed pipe to mix with the molten metal, thus optimizing the molten metal, reducing porosity and inclusions, improving the fluidity of the molten metal, and thereby improving the surface quality of the support. This process eliminates air bubbles in the molten metal. A cooling component can cool the molten metal in the casting pipe, achieving the goal of high-temperature furnace exit and low-temperature casting. Furthermore, the cooling of different molten metals can be controlled according to their material type. The time required allows different molten metals to be cast into the mold assembly at the optimal temperature. The defoaming component can defoam the molten metal in the casting pipe to ensure the quality of the molten metal and reduce the probability of bubbles and pores in the molten metal. At the same time, different defoaming agents can be used to defoam different molten metals according to different molten metal materials, so as to facilitate defoaming treatment of different molten metals. It can also ensure that the switching and adjustment of defoaming, the adjustment of molten metal cooling temperature, and the adjustment of molten metal flow rate are kept synchronized, so as to ensure the defoaming and cooling effect of different molten metals and reduce the complexity of operation.

[0008] Optionally, the driving component includes a support frame fixed on the temperature control box, a power gear and a transmission gear rotatably mounted on the support frame, the power gear and the transmission gear meshing with each other, the defoaming tank being fixedly connected to the transmission gear, and all three defoaming pipes being movably connected to the feed pipe.

[0009] By adopting the above technical solution, the driving component can facilitate the addition of a specified type of defoamer to defoam the corresponding metal liquid according to its type. When driven by the synchronizing component, the power gear, transmission gear, defoaming tank and three defoaming pipes can be rotated in sequence. When the three defoaming pipes rotate, they can be connected to the feed pipe in sequence, allowing the specified defoaming pipe to be connected to the feed pipe. The opening and closing component can open the specified defoaming pipe, allowing the defoamer to defoam the metal liquid.

[0010] Optionally, the opening and closing component includes telescopic springs fixed to the three defoaming tubes, connecting rods fixed to the three telescopic springs, adjusting blocks fixed to the three connecting rods, an electric push rod fixed to the temperature control box, and a wedge block fixed to the output shaft of the electric push rod. The three wedge blocks are movably fitted with the connecting rods. The inner side of each of the three defoaming tubes is provided with a storage groove. The three adjusting blocks are slidably connected to the three storage grooves respectively. The heights of the three connecting rods are different.

[0011] By adopting the above technical solution, the opening and closing of a designated defoaming tube can be controlled by the opening and closing components and the driving components. The electric push rod drives the wedge block to move up and down. The position of the wedge block can be adjusted according to the connecting rods of different heights. When the height of the wedge block is adjusted, the driving component drives the rotation of the three connecting rods, so that the corresponding connecting rods are in contact with the wedge block. Through the inclined surface characteristics of the wedge block, the connecting rods and the adjusting block can be squeezed in sequence, so that the telescopic spring is in a compressed state, and the adjusting block is pushed into the receiving groove in the defoaming tube, which can open the defoaming tube. The opening of a designated defoaming tube can be controlled by the contact and abutment of the wedge block with the connecting rods of different heights.

[0012] Optionally, the adjusting component includes an adjusting frame movably mounted on the casting pipe, a movable rod fixed on the adjusting frame, an annular spring fixed on the movable rod, and three arc-shaped wedges rotatably mounted on the temperature control box. The three arc-shaped wedges are all movably fitted with the movable rod, and the three arc-shaped wedges are respectively located below the three defoaming chambers. The slope height of the three arc-shaped wedges is different. The annular spring is fixedly connected to the temperature control box, and a liquid gap is provided between the bottom of the adjusting frame and the interior of the casting pipe.

[0013] By adopting the above technical solution, the flow rate of the molten metal can be adjusted by the adjusting component to control the casting speed of different molten metals. When the synchronizing component is driven, it can drive the three arc-shaped wedges to rotate. Due to the inclined surface characteristics of the arc-shaped wedges, when the arc-shaped wedges abut against the movable rod, the ring spring can be compressed. This can sequentially drive the movable rod and the adjusting frame to move up and down, thereby adjusting the size of the liquid gap in the casting pipe. Depending on the contact between the movable rod and the arc-shaped wedges at different heights, the size of the liquid gap between the adjusting frame and the casting pipe can be controlled, so as to adjust the flow rate of different molten metals according to the type of molten metal.

[0014] Optionally, the switching component includes a three-way valve and a three-way valve fixed to the three-way connector, a first gear fixed to the three-way valve, a second gear fixed to the three-way valve, a threaded rod rotatably mounted on the temperature control box, a threaded block movably mounted inside the temperature control box, and a fixed rack fixed to the threaded block. The first gear and the second gear are both movably meshed with the fixed rack. The threaded rod is threadedly connected to the threaded block. The outlet of the casting pipe, the inlet of the first connector, and the top interface of the three-way connector are respectively connected to the three interfaces of the three-way valve. The outlet of the first connector, the inlet of the second connector, and the middle interface of the three-way connector are respectively connected to the three interfaces of the three-way valve.

[0015] By adopting the above technical solution, the switching component can adjust the flow path of the molten metal according to its type. Combined with the cooling component, the cooling time of different molten metals can be controlled. When the synchronizing component drives the threaded rod to rotate, it sequentially drives the threaded block and the fixed rack to move up and down, meshing with the first gear and the second gear to rotate. The opening and closing of the three-way valve and the three-way valve interface can be adjusted. When the fixed rack meshes with the first gear, the three-way valve can be adjusted to close the connection between the casting pipe and the first connecting pipe, and open the connection between the casting pipe and the three-way connecting pipe. When the fixed rack disengages from the first gear, the three-way valve can be adjusted to open the connection between the casting pipe and the first connecting pipe, and open the connection between the casting pipe and the three-way connecting pipe. When the connection between the pipes is closed, and the fixed rack meshes with the second gear, the adjustable three-way valve closes the connection between the first and second pipes and opens the connection between the first and three-way pipes. When the fixed rack separates from the second gear, the adjustable three-way valve opens the connection between the first and second pipes and closes the connection between the first and three-way pipes. This allows molten aluminum and copper to flow sequentially through the casting pipe, the three-way pipe, and the tail of the second pipe into the mold assembly. It also allows molten aluminum and magnesium to flow sequentially through the casting pipe, the first pipe, the three-way pipe, and the tail of the second pipe into the mold assembly. Finally, it allows molten aluminum and silicon to flow sequentially through the casting pipe, the first pipe, and the second pipe into the mold assembly.

[0016] Optionally, the synchronizing element includes a motor fixed to the support frame, the threaded rod fixedly connected to the output end of the motor, the power gear fixedly connected to the threaded rod, and the three arc-shaped wedges fixedly connected to the transmission gear.

[0017] By adopting the above technical solution, the synchronous start-up of the switching component, adjusting component, driving component and opening and closing component can be ensured by the synchronization component. When the molten metal is casting, the adjustment of the defoamer switching, the molten metal cooling time and the molten metal flow rate can be controlled by only one drive source, the electric motor. The electric motor can sequentially drive the threaded rod, the power gear, the transmission gear, the defoamer tank, the three defoamer pipes, the three adjusting blocks, the three connecting rods, the three telescopic springs and the three arc-shaped wedges to rotate, which can ensure the synchronicity of various adjustments.

[0018] Optionally, the control component includes a one-way solenoid valve fixed to the feed pipe. The one-way solenoid valve, the motor, and the electric push rod are all electrically connected to the video sensor. The video sensor is fixedly connected to the support frame and is located at the inlet of the casting pipe.

[0019] By adopting the above technical solution, the amount of defoamer added can be adjusted by the control component, and the flow rate of the molten metal can be detected by the video sensor. The video sensor can transmit the signal to the one-way solenoid valve, thereby controlling the opening size of the one-way solenoid valve to the feed pipe. The flow rate of the defoamer can be controlled according to the flow rate of the molten metal to ensure the defoaming effect of the defoamer on the molten metal.

[0020] Optionally, the cooling component includes an air inlet pipe fixed to the temperature control box, multiple air outlets connected to the air inlet pipe, and a refrigeration unit connected to the air inlet pipe.

[0021] By adopting the above technical solution, the cooling component can cool the molten metal, which facilitates high-temperature unloading and low-temperature casting of the molten metal. During casting, the chiller can blow cold air into the temperature control box through the air inlet pipe and multiple air outlets in sequence. Through the circulation of the cold air in the temperature control box, the molten metal in the casting pipe, the first connecting pipe, the second connecting pipe and the three-way connecting pipe can be cooled. According to the cooling time of different molten metals, the casting temperature of different molten metals can be precisely controlled.

[0022] Optionally, the mold assembly includes four electric telescopic rods fixed to the casting frame, an upper mold, and a lower mold fixed to the output shafts of the four electric telescopic rods. The upper mold and the lower mold are movably fitted together, and the second connecting pipe is connected to the upper mold.

[0023] By adopting the above technical solution, the molten metal can be cast using the mold assembly. The lower mold can be moved up and down by four electric telescopic rods, thereby controlling the closing and opening of the lower and upper molds. When the mold is closed, the suspension bracket can be manufactured, and when the mold is opened, the cast suspension bracket can be easily removed.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Pour the refined molten metal into the casting pipe. The video sensor can monitor the molten metal, detect its type (aluminum-silicon, aluminum-magnesium, or aluminum-copper alloy), and detect its flow rate. By detecting the type and flow rate of the molten metal, the type and speed of the defoamer, as well as the flow rate and cooling time of the molten metal can be quickly adjusted. The control component can control the flow rate of the defoamer according to the flow rate of the molten metal to ensure the defoaming effect of the defoamer on the molten metal. This avoids insufficient mixing of the defoamer due to excessive flow of the molten metal, ensuring the defoaming effect of the molten metal. At the same time, it also avoids excessive mixing of the defoamer due to excessive flow of the molten metal, ensuring the quality of the molten metal and ensuring that the defoamer is mixed with the molten metal at the optimal dosage for defoaming. 2. The synchronizing component, in conjunction with the driving component and the opening and closing component, allows the defoamer in the designated defoaming chamber to flow through the defoaming pipe and the feed pipe into the casting pipe to mix with the molten metal. Depending on the type of molten metal, a specific type of defoamer can be used to defoam the corresponding molten metal. The synchronizing component, in conjunction with the adjusting component, can adjust the flow rate of the molten metal according to its type, thereby controlling the filling speed of different molten metals entering the upper and lower molds. It can also control the cooling time of different molten metals in the temperature control chamber. Furthermore, the synchronizing component, in conjunction with the switching component and the cooling component, can adjust the flow path of the molten metal according to its type, and precisely control the casting temperature of different molten metals based on their cooling time. 3. When the molten metal is an aluminum-copper alloy, polyether defoamers can be mixed with the molten aluminum-copper metal for defoaming treatment, minimizing the cooling time of the molten aluminum-copper metal in the pipeline and appropriately accelerating the flow rate of the molten aluminum-copper metal in the pipeline. When the molten metal is an aluminum-magnesium alloy, alcohol defoamers can be mixed with the molten aluminum-magnesium metal for defoaming treatment, ensuring a moderate cooling time of the molten aluminum-magnesium metal in the pipeline and maintaining a moderate flow rate of the molten aluminum-magnesium metal in the pipeline. When the molten metal is an aluminum-silicon alloy, organosilicon defoamers can be mixed with the molten aluminum-silicon metal for defoaming treatment, maximizing the cooling time of the molten aluminum-silicon metal in the pipeline and appropriately reducing the flow rate of the molten aluminum-silicon metal in the pipeline. Furthermore, it is possible to quickly switch defoamers according to different casting materials of the suspension bracket and control the optimal casting temperature of different molten metals, improving the processing efficiency of different suspension brackets. It can ensure that different molten metals are discharged at high temperatures and cast at low temperatures, allowing different molten metals to be cast into the mold at the optimal casting temperature. It can enable the casting equipment to process a variety of different molten metal alloys and ensure the casting quality of different types of bracket castings. Attached Figure Description

[0038] The most common types of suspension brackets are aluminum-silicon, aluminum-magnesium, and aluminum-copper alloy brackets. During the casting process of aluminum-silicon alloy brackets, an organosilicon defoamer (mainly composed of polysiloxane and silicon dioxide) needs to be added to the molten aluminum-silicon metal. During the smelting and casting process, aluminum-silicon alloys are prone to producing fine, stable foam due to the decomposition of grease or coatings introduced from the raw materials, or the reaction between the melt and moisture in the mold. Organosilicon has extremely low surface tension and can quickly spread on the bubble film, destroying the surface elasticity of the film and causing the bubbles to merge and rupture. During the casting process of aluminum-magnesium alloy brackets, an alcohol-based defoamer (mainly composed of n-butanol, isopropanol, and emulsifiers) needs to be added to the molten aluminum-magnesium metal. The extremely high reactivity of magnesium in aluminum-magnesium alloys means that during smelting, magnesium readily reacts with moisture to generate hydrogen gas and form porous, loose magnesium oxide scum. Alcohols (such as n-butanol and isopropanol) can decompose and consume moisture on the surface of the melt and in the furnace atmosphere at high temperatures, fundamentally reducing the amount of hydrogen scum. Sources of defoaming: During the casting process of aluminum-copper alloy brackets, polyether defoamers (mainly composed of polyether compounds and emulsifiers) need to be added to the molten aluminum-copper metal. Aluminum-copper alloys have poor casting performance, a high tendency to hot cracking, and a wide solidification range. The bubbles in their melt are often small, dispersed, and stable. Polyether defoamers (such as polyoxypropylene glycerol ether) have good dispersibility in high-temperature aluminum melts, are less likely to produce fisheyes or surface defects, and have the least impact on the purity of the final casting. Therefore, during the casting process of different materials, in order to ensure the quality of different castings, it is necessary to use a specific type of defoamer to defoam the specific molten metal. If other defoamers are used incorrectly during casting, the surface of the suspension bracket will become cloudy, discolored, or layered. This is because if other types of defoamers have poor compatibility with the molten metal, they will not be able to disperse evenly, resulting in impurities remaining, making the casting prone to cracking and shrinkage, leading to the scrapping of the suspension bracket and reducing its service life.

[0039] The aluminum-silicon, aluminum-magnesium, and aluminum-copper alloy supports are all lightweight materials. To ensure that the molten metal is poured into the mold at the optimal temperature, the casting pipe 3, the first connecting pipe 4, and the second connecting pipe 5 are bent and assembled in the temperature control box 2 to ensure that the casting pipe 3 has sufficient length. The casting pipe 3, the first connecting pipe 4, the second connecting pipe 5, and the three-way connecting pipe 6 are all made of materials that are resistant to high temperatures and corrosion and do not easily react chemically with the molten metal, such as ceramics, graphite, or special alloys, to avoid the residue and adhesion of molten metal on the inner wall of the casting pipe 3. By optimizing the fluidity and solidification characteristics of aluminum-silicon alloy, aluminum-magnesium alloy, and aluminum-copper molten metal, the risk of residue is reduced from the source. Moreover, the chemical interaction is weak, the impact on production is extremely low, and there is no significant impact on product performance and production efficiency. Under the conditions of reasonable alloy composition design, optimized process parameters, and selection of appropriate mold materials, the three alloys can share the same casting system, and the residual impact can be completely ignored. This allows for the use of the same equipment to produce multiple alloys under the market demand of multiple varieties and small batches, which can improve economic efficiency.

[0040] The optimal tapping temperature for aluminum-silicon alloys, aluminum-magnesium alloys, and aluminum-copper molten metal is typically between 760-780℃. This is because all three alloys require high temperatures to fully dissolve alloying elements (such as silicon, magnesium, and copper). 760-780℃ ensures uniform distribution of all elements, preventing segregation. High temperatures also reduce melt viscosity and improve degassing and slag removal efficiency. During the casting stage, the optimal tapping temperature for these alloys is typically between 690-740℃. Excessively high casting temperatures (>740℃) increase the gas absorption of the molten aluminum, making the casting prone to porosity. Conversely, excessively low temperatures (<690℃) result in insufficient fluidity, easily leading to cold shuts. The 690-740℃ range balances these risks, reducing hot cracking. All three alloys can achieve grain refinement and defect control within this range, ultimately achieving unified process parameters. If the cooling temperature cannot meet the individual requirements of different metal materials, casting defects will surge, easily leading to casting scrap and failing to guarantee the quality of different castings.

[0041] Although the tapping and casting temperatures of aluminum-silicon alloys, aluminum-magnesium alloys, and aluminum-copper molten metals are roughly in the same range, under the same cooling conditions, aluminum-copper alloys cool down the fastest, aluminum-silicon alloys cool down the slowest, and aluminum-magnesium alloys fall in between. This is because the three alloys have significant differences in their specific heat capacity and latent heat of solidification. Specific heat capacity determines how much heat a molten metal needs to lose to cool down by 1°C in its liquid state; the higher the specific heat capacity, the slower the cooling. Latent heat of solidification determines the additional heat a molten metal needs to release to solidify at its freezing point; the higher the latent heat, the more heat is released during solidification. The longer the solidification point is maintained, the slower the overall cooling rate. The aluminum-silicon alloy cools the slowest because it has the largest specific heat capacity and the largest latent heat of solidification. The aluminum-copper alloy cools the fastest because its specific heat capacity and latent heat of solidification are the smallest among the three. The various thermophysical parameters of the aluminum-magnesium alloy are between the two, so its cooling rate is also at an intermediate level. Therefore, in order to ensure that the aluminum-silicon alloy, aluminum-magnesium alloy and aluminum-copper molten metal are poured into the lower mold 35 and upper mold 36 at the optimal casting temperature and to ensure the efficiency of different casting processing, the cooling time of the aluminum-silicon molten metal needs to be slow, the cooling time of the aluminum-magnesium molten metal needs to be stable, and the cooling time of the aluminum-copper molten metal needs to be accelerated.

[0042] Under the same temperature, superheat, and casting pressure, aluminum-silicon molten metal has the fastest flow rate, aluminum-magnesium alloy has a medium flow rate, and aluminum-copper alloy has the slowest flow rate. This is because aluminum-silicon alloy has a narrow crystallization temperature range, making it less prone to forming dendritic skeletons during cooling, thus maintaining rapid flow over long distances. Although aluminum-magnesium alloy also has a narrow solidification range, its surface easily forms a thick and loose oxide film, generating significant viscous resistance and reducing the flow rate. Aluminum-copper alloy has a wide crystallization range, and its flow front cools rapidly, quickly precipitating dendrites and forming a network structure, resulting in a sharp increase in viscosity and premature cessation of flow. Therefore, this application aims to avoid the difference in flow rate affecting the cooling efficiency of aluminum-silicon alloy, aluminum-magnesium alloy, and aluminum-copper molten metal. Consequently, aluminum-copper molten metal needs to have a faster flow rate, aluminum-silicon molten metal needs to have a slower flow rate, and aluminum-magnesium molten metal needs to maintain a medium flow rate.

[0043] The implementation principle of the casting device for a lightweight suspension bracket in this application embodiment is as follows: (1) When it is necessary to cast the suspension bracket, the material for casting the suspension bracket is first refined, and then the refined molten metal is poured into the casting pipe 3. During the process of pouring the molten metal into the casting pipe 3, the molten metal can be monitored by the video sensor 33, the type of molten metal can be detected, and the molten metal can be quickly detected as aluminum-silicon, aluminum-magnesium or aluminum-copper. At the same time, during the process of monitoring the molten metal by the video sensor 33, the flow rate of the molten metal can be determined. By detecting the type of molten metal and the flow rate, it is convenient to quickly adjust the type and speed of defoamer, as well as the flow rate and cooling time of the molten metal. (2) The motor 10 can drive the threaded rod 11, the power gear 12, the transmission gear 13, the defoaming tank 8, the three defoaming pipes 9, the three adjusting blocks 28, the three connecting rods 29, the three telescopic springs 30 and the three arc wedges 25 to rotate in sequence. When the three defoaming pipes 9 rotate, they can be connected to the feed pipe 7 in sequence, so that the specified defoaming pipes 9 can be connected to the feed pipe 7, so that the specified type of defoaming agent can be added to defoam the corresponding metal liquid according to the different types of metal liquid. When the three arc wedges 25 rotate, they can abut against the movable rod 23 in sequence, so that the specified arc wedges 25 can abut against the movable rod 23, so that the flow rate of the metal liquid can be adjusted according to the different types of metal liquid, and the cooling time of the metal liquid is not affected by the difference in flow rate. (3) When the threaded rod 11 rotates, it can sequentially drive the threaded block 14 and the fixed rack 15 to move up and down. The fixed rack 15 can sequentially mesh with the first gear 17 and the second gear 19 to make it rotate. The opening and closing of the three-way valve 16 and the three-way valve 18 can be adjusted. When the fixed rack 15 meshes with the first gear 17, the three-way valve 16 can be adjusted to close the connection between the casting pipe 3 and the first connecting pipe 4 and open the connection between the casting pipe 3 and the three-way connecting pipe 6. When the fixed rack 15 separates from the first gear 17, the three-way valve 16 can be adjusted to close the connection between the casting pipe 3 and the first connecting pipe 4. The connection between pipes 4 is open, and the connection between casting pipe 3 and three-way connector 6 is closed. When the fixed rack 15 meshes with the second gear 19, the adjustable three-way valve 18 can close the connection between the first connector 4 and the second connector 5 and open the connection between the first connector 4 and the three-way connector 6. When the fixed rack 15 and the second gear 19 are separated, the adjustable three-way valve 18 can open the connection between the first connector 4 and the second connector 5 and close the connection between the first connector 4 and the three-way connector 6, so as to adjust the flow path of the molten metal according to the type of molten metal. (4) The electric push rod 31 can drive the wedge block 32 to move up and down, and the height of the wedge block 32 can be adjusted. The position of the wedge block 32 can be adjusted according to the connecting rod 29 of different heights. When the height of the wedge block 32 is adjusted, the rotation of the three connecting rods 29 causes the corresponding connecting rod 29 to be in contact with the wedge block 32. Through the inclined surface characteristics of the wedge block 32, the connecting rod 29 and the adjusting block 28 can be squeezed in sequence, so that the telescopic spring 30 is in a compressed state, and the adjusting block 28 is pushed into the storage groove in the defoaming tube 9, so that the defoaming tube 9 is opened. Furthermore, based on the contact and abutment between the wedge block 32 and the connecting rod 29 at different heights, the opening of the designated defoaming pipe 9 can be controlled, allowing the defoaming agent in the designated defoaming chamber to flow through the defoaming pipe 9 and the feed pipe 7 into the casting pipe 3 to mix with the molten metal, thus optimizing the defoaming treatment of the molten metal. At the same time, when the molten metal stops casting, the electric push rod 31 can drive the wedge block 32 to move and separate from the connecting rod 29. Through the elastic force of the telescopic spring 30, the connecting rod 29 and the adjusting block 28 are moved, causing the adjusting block 28 to move out of the receiving groove, which can automatically close the defoaming pipe 9 and stop the delivery of the defoaming agent. (5) When the three arc wedges 25 rotate, the inclined surface characteristics of the arc wedges 25 allow the ring spring 24 to be compressed when the arc wedges 25 abut against the movable rod 23. This can sequentially drive the movable rod 23 and the adjusting frame 22 to move up and down. The size of the liquid gap in the casting pipe 3 can be adjusted by the up and down movement of the adjusting frame 22. The size of the liquid gap between the adjusting frame 22 and the casting pipe 3 can be controlled according to the contact between the movable rod 23 and the arc wedges 25 at different heights. The flow rate of the molten metal can be adjusted to control the filling speed of different molten metals entering the upper mold 36 and the lower mold 35. The cooling time of different molten metals in the temperature control box 2 can also be controlled. (6) The flow rate of the molten metal detected by the video sensor 33 can be transmitted to the one-way solenoid valve 21, so that the one-way solenoid valve 21 can adjust the opening size of the feed pipe 7, so as to adjust the amount of defoamer added. When the flow rate of the molten metal is too fast, the feed pipe 7 can be opened larger to increase the addition speed of the defoamer. When the flow rate of the molten metal is too slow, the feed pipe 7 can be opened smaller to reduce the addition speed of the defoamer. The flow rate of the defoamer can be controlled according to the flow rate of the molten metal to ensure the defoaming effect of the defoamer on the molten metal, and avoid the defoamer not being fully mixed due to the molten metal flowing too fast, thus ensuring the defoaming effect of the molten metal. At the same time, it can also avoid the defoamer being mixed in large quantities due to the molten metal flowing too slowly, thus ensuring the quality of the molten metal and allowing the defoamer to be mixed with the molten metal at the optimal dosage for defoaming. (7) When the molten metal flows in the casting pipe 3, the first connecting pipe 4, the second connecting pipe 5 and the three-way connecting pipe 6, the chiller can blow cold air into the temperature control box 2 through the air inlet pipe 26 and multiple air outlets 27 in sequence. By circulating the cold air in the temperature control box 2, the molten metal in the casting pipe 3, the first connecting pipe 4, the second connecting pipe 5 and the three-way connecting pipe 6 can be cooled down. According to the cooling time of different molten metals, the casting temperature of different molten metals can be precisely controlled. (8) When the molten metal is an aluminum-copper alloy, the defoaming pipe 9 located on the polyether defoaming chamber will be in contact with the feed pipe 7, so that the fixed rack 15 meshes with the first gear 17, the arc-shaped wedge 25 located below the polyether defoaming chamber will be in contact with the movable rod 23, and the connecting rod 29 located below the polyether defoaming chamber will abut against the wedge 32. Thus, when the aluminum-copper molten metal flows in the casting pipe 3, the polyether defoaming agent in the polyether defoaming chamber can flow through the corresponding defoaming pipe 9 and feed pipe 7 into the casting pipe 3 to mix and defoam with the aluminum-copper molten metal. The bracket 22 can minimize the liquid gap in the casting pipe 3, which can appropriately accelerate the flow speed of the aluminum and copper molten metal in the pipe. The aluminum and copper molten metal mixed with polyether defoamer flows sequentially through the casting pipe 3, the three-way connector 6, and the tail of the second connector 5 into the upper mold 36 and the lower mold 35. This allows the aluminum and copper molten metal to flow quickly into the upper mold 36 and the lower mold 35 for casting. It also shortens the cooling time of the aluminum and copper molten metal in the temperature control box 2, allowing the aluminum and copper molten metal to enter the upper mold 36 and the lower mold 35 at the optimal casting temperature for molding and casting. (9) When the molten metal is an aluminum-magnesium alloy, the defoaming pipe 9 located on the alcohol defoaming chamber will be in contact with the feed pipe 7, so that the fixed rack 15 meshes with the second gear 19, the arc-shaped wedge 25 located below the alcohol defoaming chamber will be in contact with the movable rod 23, and the connecting rod 29 located below the alcohol defoaming chamber will abut against the wedge 32. Thus, when the aluminum-magnesium molten metal flows in the casting pipe 3, the alcohol defoaming agent in the alcohol defoaming chamber can flow through the corresponding defoaming pipe 9 and feed pipe 7 into the casting pipe 3 to mix and defoam with the aluminum-magnesium molten metal. Adjusting frame 22 The liquid gap in the casting pipe 3 can be adjusted to a suitable level, so that the flow speed of the aluminum-magnesium molten metal in the pipe can be kept at a suitable level. The magnesium molten metal mixed with alcohol defoamer can flow sequentially through the casting pipe 3, the first connecting pipe 4, the three-way connecting pipe 6 and the tail of the second connecting pipe 5 into the upper mold 36 and the lower mold 35. The aluminum-magnesium molten metal can flow into the upper mold 36 and the lower mold 35 at a medium speed for casting. The cooling time of the aluminum-magnesium molten metal in the temperature control box 2 can be moderate, so that the aluminum-magnesium molten metal enters the upper mold 36 and the lower mold 35 at the optimal casting temperature for forming and casting. (10) When the molten metal is an aluminum-silicon alloy, the defoaming pipe 9 located on the silicone defoaming chamber will be in contact with the feed pipe 7, causing the fixed rack 15 to separate from the first gear 17 and the second gear 19. The arc-shaped wedge 25 located below the silicone defoaming chamber will be in contact with the movable rod 23, and the connecting rod 29 located below the silicone defoaming chamber will abut against the wedge 32. Thus, when the aluminum-silicon molten metal flows in the casting pipe 3, the silicone defoamer in the silicone defoaming chamber can flow through the corresponding defoaming pipe 9 and feed pipe 7 into the casting pipe 3 to mix with the aluminum-silicon molten metal. The defoaming process involves adjusting the liquid gap in the casting pipe 3 to its maximum using the adjusting frame 22. This can appropriately reduce the flow rate of the aluminum-magnesium molten metal in the pipe, allowing the aluminum-silicon molten metal mixed with the organosilicon defoamer to flow sequentially through the casting pipe 3, the first connecting pipe 4, and the second connecting pipe 5 into the upper mold 36 and the lower mold 35. This allows the aluminum-silicon molten metal to flow slowly into the upper mold 36 and the lower mold 35 for casting, and allows the aluminum-silicon molten metal to cool for a longer time in the temperature control box 2. This ensures that the aluminum-silicon molten metal enters the upper mold 36 and the lower mold 35 at the optimal casting temperature for molding and casting. (11) Based on the above principle, the defoamer can be quickly switched according to the different casting materials of the suspension bracket and the temperature of the molten metal during casting can be controlled, which improves the processing efficiency of the suspension bracket. It can ensure that the molten metal is discharged at high temperature and cast at low temperature, so that different molten metals are cast in the mold at the best casting temperature. When casting molten metal, the adjustment of the defoamer switching, the molten metal cooling time and the molten metal flow rate can be controlled by only one drive source of the motor 10, so that the various synchronous adjustments of the defoamer switching, the molten metal cooling time and the molten metal flow rate can be realized. It can avoid the situation of adjustment error, and at the same time save energy consumption. It is not necessary to use multiple drive sources to adjust the defoamer switching, the molten metal cooling time and the molten metal flow rate. If a drive source is adjusted incorrectly, the quality of the bracket casting cannot be guaranteed. It reduces the complexity of the operator's operation and the possibility of error. It can enable the casting device to process a variety of different molten metal alloys and ensure the casting quality of different types of bracket castings. (12) The lower mold 35 can be moved up and down by four electric telescopic rods 34, thereby controlling the closing and opening of the lower mold 35 and the upper mold 36. When the mold is closed, the suspension bracket can be manufactured, and when the mold is opened, the cast suspension bracket can be taken out.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
