Description

Technical Field

[0001] The present invention relates to the technical field of automotive aluminum alloy wheel manufacturing, and particularly to a casting device for manufacturing automotive aluminum alloy wheels. Background Art

[0002] An aluminum alloy wheel refers to an automotive wheel made of aluminum alloy material. It is the central part that supports the tire inside the automotive tire and is also an important component connecting the tire and the vehicle. During the production and manufacturing process of aluminum alloy wheels, they are usually formed by casting. The casting devices used in the manufacturing of automotive aluminum alloy wheels mainly include: gravity casting devices, low-pressure casting devices, and squeeze casting devices, among which the low-pressure casting device is the most widely used.

[0003] During the manufacturing process of automotive aluminum alloy wheels using a low-pressure casting device, the transfer furnace storing the molten metal is connected to the wheel mold through a riser tube. After multiple castings, alloy residues solidified due to temperature drop will exist in the riser tube, so it needs to be cleaned regularly. Generally, it is necessary to wait for the transfer furnace to cool down and then clean it together with the transfer furnace. The operation is relatively cumbersome. Moreover, the riser tube after long-term use is easily eroded by the molten metal and scrapped, which not only increases the cost but may also cause the molten metal to increase in iron and deteriorate in performance, and needs to be replaced regularly. In the prior art, the furnace cover and the riser tube are first removed from the transfer furnace and then disassembled and replaced. The entire replacement step of the riser tube is also relatively cumbersome. Therefore, the present application provides a casting device for manufacturing automotive aluminum alloy wheels to meet the demand. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a casting device for manufacturing automotive aluminum alloy wheels to solve the problems of cumbersome cleaning of the riser tube of the existing casting device and cumbersome disassembly and replacement after scrapping.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A casting device for manufacturing automotive aluminum alloy wheels, including a support frame, on the top of the support frame is assembled a wheel mold, and symmetrically installed on the inner side of the support frame are first servo motors. A threaded rod is fixedly connected to the drive shaft of the first servo motor. An elevating platform is sleeved outside the two threaded rods. A transfer furnace is placed on the elevating platform. The top of the transfer furnace is closed by a furnace cover. A lifting pipe is sleeved in the middle of the furnace cover. A second servo motor is fixedly installed on the top of the support frame. The drive shaft of the second servo motor extends to the inner side of the support frame and is fixedly connected to a movable plate; a cleaning component for the regular cleaning of the lifting pipe, and the cleaning component is connected to the movable plate; a connecting component for the assembly connection between the lifting pipe and the furnace cover, and the connecting component is respectively connected to the furnace cover and the lifting pipe; a disassembly component for the disassembly after the lifting pipe is scrapped, and the disassembly component is connected to the cleaning component.

[0007] Optionally, a casting port adapted to the top end of the lifting pipe is opened at the bottom of the wheel mold. Two groups of limiting plates are fixedly connected below the top plate of the support frame. The two groups of limiting plates are distributed on both sides of the movable plate.

[0008] Optionally, the cleaning component includes a connecting rod fixedly connected below the end of the movable plate. The bottom end of the connecting rod is fixedly connected with a cleaning disc, and the length value of the connecting rod is greater than the length value of the lifting pipe. The shape of the cleaning disc is adapted to the inner wall shape of the lifting pipe.

[0009] Optionally, the connecting component includes a connecting seat fixedly connected to the furnace cover and a positioning block fixedly connected to the outside of the lifting pipe. Connecting blocks are symmetrically installed in the connecting seat. A connecting groove adapted to the shape of the connecting block is opened on the outside of the positioning block.

[0010] Optionally, a sliding cavity adapted to the shape of the connecting block is opened in the connecting seat. Elastic sheets are symmetrically connected to the outside of the connecting block. The end of the elastic sheet is fixedly connected with a fixing plate, and the middle of the elastic sheet is bent in a wavy shape and provided with a first weakened groove.

[0011] Optionally, a first buffer sheet is fixedly connected to the surface of the connecting block close to the elastic sheet. A second buffer sheet corresponding to the position of the first buffer sheet is fixedly connected to the outside of the fixing plate. Rubber strips are fixedly connected evenly below the first buffer sheet and above the second buffer sheet. Second weakened grooves are opened on the outside of the first buffer sheet and the second buffer sheet.

[0012] Optionally, the disassembly component includes telescopic blocks sleeved in the cleaning tray and evenly distributed. Assembly grooves adapted to the shapes of the telescopic blocks are formed in the cleaning tray, and the telescopic blocks and the connecting rod are fixedly connected by springs.

[0013] Optionally, baffles are arranged on both sides of the telescopic block. Activity grooves adapted to the shapes of the baffles are formed in the assembly grooves, and a clamping groove adapted to the shape of the bottom end of the liquid lifting pipe is formed at the end of the telescopic block.

[0014] Optionally, docking plates adapted to the sizes of the connection seats are symmetrically connected to the bottom of the movable plate. A first channel communicating with the inside of the docking plate is formed in the movable plate. First docking holes are formed on the outside of the docking plate, and an air pump communicating with the first channel is fixedly connected to the bottom of the movable plate.

[0015] Optionally, a second channel communicating with the first channel is formed in the middle of the connecting rod. Third docking holes adapted to the sizes of the first docking holes are formed on the outside of the connection seat. Second docking holes adapted to the sizes of the third docking holes are formed on the outside of the positioning block. A third channel communicating with the second docking hole is formed in the positioning block, and a communication port communicating with the third channel is formed in the connection groove.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up the cleaning component, after the position of the cleaning component is adjusted by the second servo motor, during the rising process of the lifting platform, the transfer furnace and the furnace cover can be driven to move upward, and then the cleaning tray at the bottom end of the connecting rod can enter the inside of the liquid lifting pipe to scrape and clean the inner wall of the liquid lifting pipe, scrape off the residual residues inside the liquid lifting pipe, and achieve the cleaning effect of the liquid lifting pipe. The existing equipment in the original casting device is reasonably utilized to efficiently and automatically realize the mechanical cleaning operation, reducing the labor intensity of the staff.

[0018] By setting up the connection component, the air pump and the first channel, the connection relationship between the liquid lifting pipe and the furnace cover is stable and reliable, and the method of releasing the fixed state is simple and convenient. As long as the air pump works and inflates into the third channel, the connecting block can be pushed away from the connection groove by air pressure, and the connection and fixation state between the connection seat and the liquid lifting pipe can be released, and correspondingly, the connection relationship between the furnace cover and the liquid lifting pipe can be disconnected, so that the liquid lifting pipe can be removed from the outside of the furnace cover, facilitating the subsequent disassembly work.

[0019] By setting up a disassembly component, after the cleaning disk penetrates through the bottom of the riser pipe, the air pump can operate and drive the disassembly component to work, causing the telescopic block to extend from the outside of the cleaning disk. After the connection component disconnects the connection and fixation state between the riser pipe and the connection seat, during the process of the furnace cover and the transfer furnace descending, the telescopic block can lift the bottom end of the riser pipe, and then the riser pipe is separated from the furnace cover, realizing the disassembly of the riser pipe, making the disassembly operation of the riser pipe simple and convenient. The structure of the entire disassembly component is ingenious and forms a cooperation with the structure of the connection component, making ingenious use of the air inflation operation of the air pump to simultaneously disconnect the connection component and start the disassembly component.

[0020] By setting up the telescopic block and the card slot in the disassembly component, when the telescopic block extends from the cleaning disk and assists in the disassembly process of the riser pipe, the bottom end of the riser pipe is clamped in the card slot on the telescopic block. Then, as a displacement occurs between the riser pipe and the connection seat, the first docking hole, the third docking hole, and the second docking hole are also misaligned. At this time, the air pump stops working, and the telescopic block is no longer affected by the air pressure. It relies on the clamping between the card slot and the bottom of the riser pipe to maintain the relative position between the telescopic block and the riser pipe fixed, so as to ensure the stability of the telescopic block during the entire disassembly process of the riser pipe, reduce the working time of the air pump, and lower the energy consumption of the entire device during the disassembly of the riser pipe.

[0021] By setting up the elastic sheet, the first buffer sheet, the second buffer sheet, and the rubber strip in the connection component, when the connection block withdraws from the connection slot, it will cause the elastic sheet to deform at the first weakening slot and drive the first buffer sheet and the second buffer sheet to approach each other. Then, contact occurs between the rubber strips on the first buffer sheet and the second buffer sheet. After the connection block and the connection slot are misaligned, during the process of the elastic sheet resetting, it is subject to the resistance of the rubber strip and there is a certain delay, thereby reducing the resistance received during the disassembly of the riser pipe, facilitating the disassembly operation of the riser pipe, and further improving the function of the disassembly component.

[0041] As Figures 1 to 10As shown, an embodiment of the present invention provides a casting device for manufacturing automobile aluminum alloy wheels, including a support frame 1, a wheel hub mold 2 is assembled on the top of the support frame 1, and a first servo motor 4 is symmetrically installed on the inner side of the support frame 1, a threaded rod 5 is fixedly connected to the driving shaft of the first servo motor 4, and a lifting platform 6 is sleeved on the outer side of the two threaded rods 5, and a transfer furnace 3 is placed on the lifting platform 6. The support frame 1 is the supporting structure of the entire device, providing a stable working environment and installation position for other equipment and structures. When the first servo motor 4 is working, it can drive the threaded rod 5 to rotate through its driving shaft, and then push the lifting platform 6 to move up and down in the support frame 1 through the threaded connection relationship between the threaded rod 5 and the lifting platform 6, and then drive the transfer furnace 3 to move up and down. The top of the transfer furnace 3 is closed by a furnace cover 18, and a liquid riser 14 is sleeved in the middle of the furnace cover 18.

[0042] A second servo motor 7 is fixedly installed on the top of the support frame 1. The drive shaft of the second servo motor 7 extends to the inner side of the support frame 1 and is fixedly connected to a movable plate 8. A casting port that is compatible with the top of the riser pipe 14 is provided at the bottom of the hub mold 2. When the transfer furnace 3 follows the lifting platform 6 to move to the highest point in the support frame 1, the riser pipe 14 in the middle of the furnace cover 18 is docked with the casting port at the bottom of the hub mold 2. Two air inlet valves are also provided on the furnace cover 18. After being connected to the air pressure equipment, they can pressurize the interior of the transfer furnace 3, and then use the air pressure to push the molten metal in the hub mold 2 through the riser pipe 14 for casting into the hub mold 2. The principles and usage methods of the transfer furnace 3 and the furnace cover 18 are the same as those in the prior art and will not be described in detail here. Two groups of limit plates 11 are connected, and the two groups of limit plates 11 are distributed on both sides of the movable plate 8. When the second servo motor 7 is working, it can drive the movable plate 8 to deflect through its drive shaft, and drive the structure associated with the movable plate 8 to produce corresponding displacement. The limit plates 11 are used to limit the range of movement of the movable plate 8. The two limit plates 11 are distributed near the middle and edge positions of the top plate of the support frame 1. When the movable plate 8 deflects and contacts with the limit plate 11 near the middle of the support frame 1, the end position of the movable plate 8 corresponds to the casting port position of the hub mold 2, and when the movable plate 8 deflects and contacts with the limit plate 11 at the edge position of the support frame 1, the movable plate 8 and the related structures outside the movable plate 8 are all stored at the edge position of the support frame 1, so as to avoid obstruction to the lifting and lowering of the transfer furnace 3 in the support frame 1.

[0043] The cleaning component is used for regular cleaning of the riser pipe 14. The cleaning component is connected to the movable plate 8. The cleaning component can use the lifting platform 6 to drive the transfer furnace 3 to rise, so that the cleaning component can enter the interior of the riser pipe 14 and scrape and clean the inner wall of the riser pipe 14; the connecting component is used for the assembly connection between the riser pipe 14 and the furnace cover 18. The connecting component is connected to the furnace cover 18 and the riser pipe 14 respectively. The connecting component is used to maintain the connection relationship between the furnace cover 18 and the riser pipe 14, ensuring that the riser pipe 14 can stably transfer the metal stored in the transfer furnace 3 The liquid is input into the wheel hub mold 2 to form the wheel hub; a disassembly component is used for disassembling the riser pipe 14 after it is scrapped. The disassembly component is connected to the cleaning component. The disassembly component is used to assist in the separation and disassembly between the riser pipe 14 and the furnace cover 18. After the connection component is disconnected, the bottom of the riser pipe 14 is limited, and the transfer furnace 3 follows the descending action of the lifting platform 6 to remove the riser pipe 14 from the furnace cover 18, thereby completing the disassembly operation of the riser pipe 14 directly without disassembling the furnace cover 18, and no manual operation is required by the staff, which is simple, efficient, stable and reliable.

[0044] In this embodiment, if Figures 1 to 3 As shown, the cleaning assembly includes a connecting rod 10 fixedly connected to the bottom end of the movable plate 8, and the bottom end of the connecting rod 10 is fixedly connected to a cleaning plate 13, and the length of the connecting rod 10 is greater than the length of the rising pipe 14. The shape of the cleaning plate 13 is adapted to the shape of the inner wall of the rising pipe 14. When it is not necessary to clean the rising pipe 14, the cleaning assembly as a whole follows the movable plate 8 and is stored at the edge position of the support frame 1 to avoid the existence of the cleaning assembly hindering the up and down movement of the transfer furnace 3 in the support frame 1. When it is necessary to clean the inside of the rising pipe 14 regularly, the second servo motor 7 works and drives the movable plate 8 to deflect through its drive shaft until The movable plate 8 drives the entire cleaning assembly to a position corresponding to the riser pipe 14. Thereafter, the transfer furnace 3 follows the lifting platform 6 to rise in the support frame 1, and then drives the riser pipe 14 upward through the furnace cover 18, so that the cleaning disc 13 is inserted from the top of the riser pipe 14. After the cleaning disc 13 enters the interior of the riser pipe 14, it contacts the inner wall of the riser pipe 14. As the transfer furnace 3 and the lifting platform 6 rise, the outer side of the cleaning disc 13 and the inner wall of the riser pipe 14 are scraped against each other, scraping off the metal residue on the inner wall of the riser pipe 14 until the cleaning disc 13 passes through the bottom of the riser pipe 14, completing the cleaning of the riser pipe 14.

[0045] In this embodiment, if Figure 5 、 Figure 8 、 Figure 9 and Figure 10As shown, the connection component includes a connection seat 19 fixedly connected to the furnace cover 18 and a positioning block 15 fixedly connected to the outside of the liquid-riser pipe 14. Connection blocks 30 are symmetrically installed in the connection seat 19. A connection groove 37 adapted to the shape of the connection block 30 is formed on the outside of the positioning block 15. The positioning block 15 is arranged outside the liquid-riser pipe 14, avoiding affecting the structure of the inner wall of the liquid-riser pipe 14 and ensuring the conveying effect of the liquid-riser pipe 14 on the molten metal. When the liquid-riser pipe 14 is sleeved in the middle of the furnace cover 18, the position of the positioning block 15 on the liquid-riser pipe 14 corresponds to the position of the connection seat 19 on the furnace cover 18. The connection block 30 in the connection seat 19 can be embedded into the connection groove 37 on the positioning block 15, forming a relative fixed relationship between the furnace cover 18 and the liquid-riser pipe 14. At the same time, no structure capable of pulling the connection block 30 is provided outside the connection seat 19, avoiding the possible mis-touch from affecting the clamping relationship between the connection block 30 and the connection groove 37, and then ensuring the stability of the entire connection component in the connected state. A sliding cavity adapted to the shape of the connection block 30 is formed in the connection seat 19. Elastic pieces 31 are symmetrically connected to the outside of the connection block 30. The end of the elastic piece 31 is fixedly connected to a fixing plate 32. After the fixing plate 32 is in close contact with the inner wall of the sliding cavity, it is fixedly connected to the connection seat 19 by bolts, forming a limit fixation for the connection block 30 and the elastic piece 31, maintaining the connection relationship between the connection block 30 and the elastic piece 31 and the connection seat 19. The middle part of the elastic piece 31 is bent in a wavy shape and provided with a first weakened groove 24. The formation of the sliding cavity allows the connection block 30 to have a space for movement. Then, when the connection block 30 is subjected to an external force, it can slide in the sliding cavity. The connection block 30 not subjected to an external force only maintains its docking relationship with the connection groove 37 under the elastic force of the elastic piece 31. When the connection block 30 is subjected to a force towards the inside of the sliding cavity, the connection block 30 will squeeze the elastic piece 31. The first weakened groove 24 formed on the elastic piece 31 makes the thickness value of the elastic piece 31 thinner and the strength weaker at the first weakened groove 24, making it easier to deform. Then, after being squeezed by the connection block 30, the elastic piece 31 can undergo corresponding deformation at the first weakened groove 24, cooperate with the displacement of the connection block 30, and store elastic potential energy. After the external force is removed, the elastic potential energy stored by the elastic piece 31 is relied on to drive the connection block 30 to reset.

[0046] On one side of the connecting block 30 close to the elastic sheet 31, a first buffer sheet 33 is fixedly connected. Outside the fixing plate 32, a second buffer sheet 34 corresponding to the position of the first buffer sheet 33 is fixedly connected. Uniformly distributed rubber strips 35 are fixedly connected below the first buffer sheet 33 and above the second buffer sheet 34. Second weakening grooves 36 are formed outside the first buffer sheet 33 and the second buffer sheet 34. The formation of the second weakening grooves 36 makes the thickness values of the first buffer sheet 33 and the second buffer sheet 34 thinner and the strength weaker at the second weakening grooves 36, making it easier to deform under the action of an external force. During the process of the connecting block 30 withdrawing from the connecting groove 37, it will drive the elastic sheet 31 to deform at the first weakening groove 24. At the same time, the first buffer sheet 33 on the connecting block 30 will also approach the second buffer sheet 34 on the fixing plate 32, and then contact will be generated between the rubber strips 35 on the first buffer sheet 33 and the second buffer sheet 34. There is a certain height difference between the first buffer sheet 33 and the second buffer sheet 34, and the rubber strips 35 on the first buffer sheet 33 and the second buffer sheet 34 are arranged on the mutually approaching sides of the first buffer sheet 33 and the second buffer sheet 34. After the connecting block 30 and the connecting groove 37 are misaligned, the rubber strip 35 on the first buffer sheet 33 can contact the rubber strip 35 on the second buffer sheet 34, and cause the first buffer sheet 33 and the second buffer sheet 34 to bend at the second weakening groove 36. Through the mutual contact between the rubber strips 35, auxiliary limiting of the first buffer sheet 33 and the second buffer sheet 34 is formed, so that during the reset process of the elastic sheet 31, the first buffer sheet 33 and the second buffer sheet 34 will be subjected to the resistance of the rubber strips 35, causing a certain delay in the reset process of the elastic sheet 31, preventing the connecting block 30 from quickly resetting under the action of the elastic sheet 31, and after withdrawing from the connecting groove 37, it will not immediately reset and clamp the outside of the liquid-elevating pipe 14, thereby reducing the resistance received during the disassembly process of the liquid-elevating pipe 14 and facilitating the disassembly operation of the liquid-elevating pipe 14.

[0047] In this embodiment, as Figures 3 to 7As shown, the disassembly component includes telescopic blocks 22 sleeved in the cleaning disc 13 and evenly distributed. Assembly grooves 21 adapted to the shape of the telescopic blocks 22 are provided in the cleaning disc 13. The telescopic blocks 22 are fixedly connected to the connecting rod 10 through springs 23. Flaps are provided on both sides of the telescopic blocks 22, and movable grooves adapted to the shape of the flaps are provided in the assembly grooves 21. The design of the flaps and the movable grooves can limit the relative movement range between the telescopic blocks 22 and the cleaning disc 13. When the telescopic blocks 22 are completely retracted into the cleaning disc 13, the ends of the telescopic blocks 22 are flush with the outside of the springs 23, forming a disc-shaped structure in cooperation with the cleaning disc 13, enabling the cleaning disc 13 to normally scrape and clean the inner wall of the liquid-rising pipe 14. A clamping groove 25 adapted to the shape of the bottom end of the liquid-rising pipe 14 is provided at the end of the telescopic block 22. When the liquid-rising pipe 14 needs to be disassembled, after the cleaning disc 13 penetrates from the bottom of the liquid-rising pipe 14, the telescopic blocks 22 in the cleaning disc 13 are pushed out. After the connecting component disconnects the connection and fixation state between the liquid-rising pipe 14 and the connecting seat 19, during the process of the furnace cover 18 and the transfer furnace 3 descending, the clamping groove 25 on the telescopic block 22 can contact the bottom of the liquid-rising pipe 14, and then the telescopic block 22 can lift the bottom end of the liquid-rising pipe 14, separating the liquid-rising pipe 14 from the furnace cover 18.

[0048] In this embodiment, as Figures 3 to 9As shown, docking plates 12 that are symmetrically connected to the bottom of the movable plate 8 and are adapted to the size of the connection seats 19 are provided. A first channel 16 that is connected to the inside of the docking plates 12 is provided in the movable plate 8. A first docking hole 17 is provided on the outside of the docking plates 12. An air pump 9 that is connected to the first channel 16 is fixedly connected to the bottom of the movable plate 8.A second channel 20 communicating with the first channel 16 is provided in the middle of the connecting rod 10. A third docking hole 29 adapted to the size of the first docking hole 17 is provided on the outer side of the connecting seat 19. A second docking hole 26 adapted to the size of the third docking hole 29 is provided on the outer side of the positioning block 15. A third channel 28 communicating with the second docking hole 26 is provided in the positioning block 15. A communication port 27 communicating with the third channel 28 is provided in the connecting groove 37. When the cleaning disk 13 passes through the bottom end of the liquid-elevating pipe 14, the docking plate 12 on the movable plate 8 is located outside the connecting seat 19. The first docking hole 17 on the docking plate 12 is docked with the third docking hole 29 on the outer side of the connecting seat 19. At this time, the furnace cover 18 and the liquid-elevating pipe 14 are in a connected and fixed state. One end of the third docking hole 29 far from the first docking hole 17 is docked with the second docking hole 26 on the positioning block 15. The first channel 16, the second channel 20 and the third channel 28 are interconnected. Then, the air filled by the air pump 9 can enter the positioning block 15 through the channel formed by the first channel 16, the first docking hole 17, the third docking hole 29 and the second docking hole 26. The air filled by the air pump 9 can also enter the cleaning disk 13 through the channel formed by the first channel 16, the second channel 20 and the assembly groove 21. Thus, the air filled by the air pump 9 can act on the inside of the cleaning disk 13 and the positioning block 15 simultaneously. The air entering the cleaning disk 13 can push the telescopic block 22 to extend out of the cleaning disk 13, while the air entering the positioning block 15 is ejected through the communication port 27 and acts on the connecting block 30, pushing the connecting block 30 to leave the connecting groove 37 and disconnecting the fixed connection between the liquid-elevating pipe 14 and the connecting seat 19. Then, after the telescopic block 22 extends out of the cleaning disk 13, it can contact the bottom end of the liquid-elevating pipe 14 as the transfer furnace 3 and the furnace cover 18 descend, blocking the liquid-elevating pipe 14 and completing the disassembly of the liquid-elevating pipe 14 during the descent of the transfer furnace 3 and the furnace cover 18. The disassembly operation of the liquid-elevating pipe 14 by the entire device can be automatically completed through the cooperation of the structure, simplifying the disassembly steps of the liquid-elevating pipe 14 and greatly reducing the labor intensity of the staff. Secondly, during the process of assisting the disassembly of the liquid-elevating pipe 14 after the telescopic block 22 extends out of the cleaning disk 13, the bottom end of the liquid-elevating pipe 14 is clamped in the clamping groove 25 on the telescopic block 22. Then, as a displacement occurs between the liquid-elevating pipe 14 and the connecting seat 19 and the first docking hole 17, the third docking hole 29 and the second docking hole 26 are misaligned and cannot form a channel, the air pump 9 also stops working. The telescopic block 22 is no longer affected by the air pressure and relies on the clamping connection between the clamping groove 25 and the bottom of the liquid-elevating pipe 14 to maintain the relative position between the telescopic block 22 and the liquid-elevating pipe 14 fixed, so as to ensure the stability of the telescopic block 22 during the entire disassembly process of the liquid-elevating pipe 14, reduce the working time of the air pump 9, lower the energy consumption of the entire device during the disassembly of the liquid-elevating pipe 14, and control the usage cost of the device.
