Description
Technical Field
[0001] The invention relates to the technical field of automobile casting, in particular to a casting device for manufacturing automobile covering parts using new materials. Background Art
[0002] In the automotive manufacturing industry, automotive panels are key components that shape the vehicle's exterior and ensure structural performance. Their quality directly affects the vehicle's aesthetics, safety, and market competitiveness. With the rapid development of new materials technology, new materials such as high-strength lightweight alloys and composite materials have gradually become the mainstream choice for automotive panel manufacturing due to their excellent mechanical properties and lightweight advantages, providing technical support for achieving energy conservation, emission reduction, and performance improvement of automobiles.
[0003] However, the application of new materials has put forward higher requirements on the casting process. In the casting process, the injection speed of the casting alloy liquid is one of the key factors affecting the quality of the casting. The traditional automobile cover casting device generally has the problem of insufficient control accuracy in the alloy liquid injection link. When the alloy liquid is injected too fast, the liquid flows at high speed inside the mold, which is very likely to cause violent splashing and turbulence. A large amount of gas is drawn into the alloy liquid to form bubbles, which leave defects such as pores and shrinkage holes inside the casting after solidification, seriously weakening the mechanical properties of the casting; at the same time, the high-speed flowing alloy liquid will also wash the inner wall of the mold, causing increased mold wear, shortening the mold service life, and increasing production costs. In addition, the splashing alloy liquid may also form metal splashes on the mold surface, affecting the surface quality and appearance accuracy of the casting;
[0004] Although some existing technologies attempt to improve the above problems by adjusting the pouring system structure or adding buffer devices, they are still unable to achieve accurate and dynamic control of the alloy liquid injection speed, and it is difficult to meet the demand for high-quality casting of new material automobile covers. Therefore, the development of a new casting device that can effectively limit the injection speed of casting alloy liquid and reduce casting defects such as bubbles is of great significance to improving the manufacturing quality and production efficiency of automobile covers and promoting technological upgrading of the automobile manufacturing industry.
[0005] Chinese patent (publication number CN115647336A), which discloses a casting method and casting device for automobile castings, solves the problem that the position of the casting is easily offset. The patent includes a device body, a casting seat is provided below the device body, a control chamber is opened in the casting seat, the bottom of the casting seat is fixedly connected to the base, the bottom of the device body is provided with a first connecting block, the top of the casting seat is provided with a first through hole, the first connecting block passes through the first through hole, the bottom end of the first connecting block is fixedly connected to the shaking block located in the casting seat, a shaking mechanism for driving the shaking block to shake is provided on the casting seat, a lower splint is provided at the bottom of the shaking block, and first tooth plates are fixedly connected on both sides of the lower splint, gears are respectively provided on the side away from the two first tooth plates, and a second tooth plate is provided on the side of the gear away from the first tooth plate; the position of the device body is avoided from being offset, and the external demolding mechanism is convenient for removing the casting.
[0006] According to the above scheme, when the above scheme is used, the clamping plate is moved toward the shaking block, and the shaking block is clamped in cooperation with the lower clamping plate. At the same time, the limiting cone is inserted into the positioning groove to make the shaking block firmly between the two clamping plates, which can prevent the main body from shifting. However, it is impossible to control the flow rate of the casting alloy liquid injection, which has limitations.

The rubber ring can enhance the sealing between the piston block 48 and the speed regulating tube 33. The outer wall of the piston block 48 is formed with a through hole 42, and the inner wall of the through hole 42 is fixedly connected to a first elastic contraction rod 41. The output end of the first elastic contraction rod 41 is fixedly connected to a first blocking plate 39, and the outer wall of the first blocking plate 39 abuts against the outer wall of the through hole 42.
[0045] The outer wall of the piston block 48 is fixedly connected to a plurality of connecting tubes 46. The plurality of connecting tubes 46 are distributed circumferentially inside the piston block 48. The connecting tubes 46 have a plurality of water-permeable holes formed at one end thereof close to the first blocking plate 39.

The bottom of the threaded tube 25 is fixedly connected to a turntable 26, and a plurality of weight-reducing holes are provided on the outer wall of the turntable 26. The plurality of weight-reducing holes are circumferentially distributed on the outer wall of the turntable 26. The bottom of the second movable plate 24 is fixedly connected to a telescopic arm 27 via a connecting plate, and one end of the telescopic arm 27 away from the second movable plate 24 is fixedly connected to the bottom of the pushing arm 29 via a matching telescopic tube 50. When the telescopic arm 27 moves upward, the matching telescopic tube 50 will contract. The interior of the piston block 48 is rotatably connected to a connecting rod 31 via a rotating shaft, and a matching torsion spring 43 is clamped between the connecting rod 31 and the piston block 48, and the matching torsion spring 43 is in a state of storing force.
[0047] The outer wall of the connecting rod 31 is slidably penetrated by the first elastic contraction rod 41 and the first blocking plate 39, and the outer wall of the connecting rod 31 is fixedly connected to a plurality of second blocking plates 40, and the outer wall of each second blocking plate 40 abuts against the outer wall of the piston block 48, and the plurality of second blocking plates 40 are circumferentially distributed on the outer wall of the connecting rod 31. The outer wall of the pushing arm 29 is rotatably connected to the second recovery pulley 32 through a rotating shaft, and the outer wall of the second recovery pulley 32 is wound with a pull rope 28, and the free end of the pull rope 28 is fixedly connected to the telescopic arm 27, and the end of the second recovery pulley 32 close to the speed regulating tube 33 is fixedly connected to the first matching shrinkage tube 30, and the first matching shrinkage tube 30 is rotatably connected to the speed regulating tube 33, and the left end of the connecting rod 31 is fixedly connected to the left end of the inner wall of the first matching shrinkage tube 30;
[0048] Specifically, the casting punch 6 moves closer to and abuts against the casting die 9, and the casting punch 6 will pull the first movable plate 18 through the third steel rope 14. The first movable plate 18 drives the elastic shrinkage plate 22 to move through the curved arm 23. When the elastic shrinkage plate 22 moves to the right side of the second liquid injection port 36, the casting alloy liquid can be poured into the liquid storage tube 17 through the second liquid injection port 36. Due to the weight, the rubber spiral tube 20 will be pulled by the moving block 38. When the elastic coefficient of the rubber spiral tube 20 is less than the overall weight of the liquid storage tube 17, the second abutment block 35 will break away from the outer wall of the first abutment block 34 and abut. When the mold is replaced, the casting alloy liquid capacity required inside the replaced mold is less than the original one. Then rotate the turntable 26, the turntable 26 drives the threaded tube 25 to rotate, and the threaded tube 25 drives the second movable plate 24 to move upward. When the second movable plate 24 moves upward, it will also bring When the dynamic elastic contraction plate 22 contracts and the second movable plate 24 moves upward, the compressed gas between the second movable plate 24 and the liquid storage tube 17 will get a larger space, the molecules of the compressed gas become smaller, and the pressure of the compressed gas at this time becomes smaller. At this time, the gas pressure inside the connecting tube 19 and the rubber spiral tube 20 becomes smaller, and the gas pressure inside the rubber spiral tube 20 becomes smaller, which means that the elasticity of the rubber spiral tube 20 becomes smaller. At this time, when the required casting alloy liquid enters the liquid storage tube 17 through the second liquid injection port 36, at this time, due to the reduced pressure inside the rubber spiral tube 20, the liquid storage tube 17 will pull the rubber spiral tube 20 to extend due to gravity, so that the second abutment block 35 is separated from the abutment with the first abutment block 34. The amount of casting alloy liquid poured each time can be reasonably controlled by the action of gravity to avoid wasting resources on the casting alloy liquid caused by pouring too much;
[0049] And when the second movable plate 24 moves upward, the telescopic arm 27 releases the pulling force on the pull rope 28. Note that when the pull rope 28 moves, it will drive the telescopic arm 27 to extend through the cooperating telescopic tube 50, so that the output end of the telescopic arm 27 is always located directly below the second recovery pulley 32, and the connecting rod 31 will reset and rotate under the action of the cooperating torsion spring 43. The connecting rod 31 drives the first cooperating shrink tube 30 and the second recovery pulley 32 to reset and rotate. When the connecting rod 31 rotates, it also drives the second blocking plate 40 to rotate. When the second blocking plate 40 rotates, it will close and block the corresponding water permeable holes, and Care should be taken to prevent the second blocking plate 40 from closing and blocking all the water holes, and since the second blocking plate 40 will block some of the water holes, when the piston block 48 moves inside the speed regulating tube 33, the speed of the piston block 48 when moving inside the speed regulating tube 33 will be reduced, and the piston block 48 will drive the curved arm 23 to push the elastic shrinkage plate 22, and the elastic shrinkage plate 22 will push out the casting alloy liquid inside the second movable plate 24, and effectively control the speed at which the casting alloy liquid is pushed out, to avoid the casting alloy liquid being pushed too fast when the casting alloy liquid is small, causing the generation of bubbles and affecting the casting.
[0050] The working principle of the present invention is:
[0051] When the present invention is used, the servo motor 12 is started, and the servo motor 12 drives the two first recovery pulleys 13 to rotate. When the first recovery pulley 13 rotates, it will recycle and pull the second steel rope 11, and the second steel rope 11 will pull the mounting plate 5 downward, and the mounting plate 5 will drive the casting punch 6 to merge with the casting die 9. At this time, the mounting plate 5 will pull the first movable plate 18 through the third steel rope 14 during the process of descending, and the first movable plate 18 will drive the first abutting block 34 and the outer wall of the second abutting block 35 to abut against each other, and the second abutting block 35 will drive the elastic shrinkage plate 22 to move through the curved arm 23, and the elastic shrinkage plate 22 will move on the upper end of the liquid storage tube 17 and the second movable plate 24. When the elastic shrinkage plate 22 moves to the right end of the inner wall of the liquid storage tube 17, the casting punch 6 and the casting die 9 are just merged. At this time, the elastic shrinkage plate 22 is on the right side of the second matching shrinkage tube 37. At this time, the casting alloy liquid can be poured into the liquid storage tube 17 through the second liquid injection port 36.
[0052] When the bending arm 23 moves, the bending arm 23 will also push the pushing arm 29, and the pushing arm 29 drives the piston block 48 to move. When the piston block 48 moves in the inner wall of the speed regulating tube 33, the third blocking plate 44 is closed against the outer wall of the connecting tube 46, and the first blocking plate 39 will be separated from the contact with the outer wall of the through-port 42. Due to the large diameter of the through-port 42, liquid water will freely pass through the inside of the through-port 42 without affecting the moving speed of the piston block 48. When the piston block 48 moves, it will also squeeze and store force on the second spring. When the casting punch 6 and the casting die 9 are merged, the casting alloy liquid is injected into the liquid storage tube 17 through the second liquid injection port 36. When the liquid level reaches When the second liquid injection port 36 is filled, the electronic valve is closed, effectively preventing the excess casting alloy liquid in the second liquid injection port 36 from falling into the inner wall of the liquid storage tube 17 at the second liquid injection port 36. At this time, the liquid storage tube 17 will stretch the rubber spiral tube 20 due to gravity. When the first abutting block 34 is separated from the outer wall of the second abutting block 35, the second spring will drive the piston block 48 to return to its original position. When the piston block 48 is returned to its original position, the first blocking plate 39 will abut against the inner wall of the through port 42, while the third blocking plate 44 will be separated from the inner wall of the connecting tube 46. Since the water permeable hole is small, the speed of the piston block 48 will be affected when water passes through the water permeable hole, and the speed of the piston block 48 will be reduced.
[0053] The piston block 48 will push the bending arm 23 through the pushing arm 29, and the bending arm 23 will drive the elastic shrinkage plate 22 to reset and move. The elastic shrinkage plate 22 will discharge the internal casting alloy liquid through the liquid storage pipe 17 to the first liquid injection port 15. The casting alloy liquid then enters the casting tank 8 through the first liquid injection port 15. At this time, when the casting alloy liquid enters the casting tank 8, the gas will be discharged through the exhaust port 21. After the casting alloy liquid is discharged, cooling water enters the cavity through the drain pipe. The cooling water will cool the casting alloy liquid. When the casting alloy liquid solidifies, the servo motor 12 drives the two first recovery pulleys 13 to reset and rotate. The first recovery pulley The take-up wheel 13 will release the second steel rope 11, and the third spring 4 will drive the mounting plate 5 and the casting punch 6 to reset. The mounting plate 5 will release the third steel rope 14, and the reset shrink tube 49 will lose the tension of the third steel rope 14. The reset shrink tube 49 will drive the first movable plate 18 to reset, and the reset of the first movable plate 18 will drive the first abutment block 34 to move. When the bottom of the first abutment block 34 abuts the upper end of the second abutment block 35, the first abutment block 34 will shrink toward the inside of the first movable plate 18. When the first abutment block 34 is separated from the abutment with the second abutment block 35, the planes between the first abutment block 34 and the second abutment block 35 will abut each other.
[0054] Note that when the liquid storage tube 17 is affected by gravity, it will move downward. Even if the liquid storage tube 17 moves downward, the liquid passage 16 and the first liquid injection port 15 are still connected because the diameters of the first liquid injection port 15 and the liquid passage 16 are sufficient for the liquid storage tube 17 to move. When the liquid storage tube 17 moves downward under the action of gravity, all the force is supported by the reset shrink tube 49 connected to the rubber spiral tube 20 through the first movable plate 18;
[0055] When the casting alloy liquid cools and solidifies, the servo motor 12 drives the two first recovery pulleys 13 to rotate in the opposite direction, which will release the second steel rope 11. At this time, the third spring 4 releases the stored force to drive the mounting plate 5 and the casting punch 6 to reset upward, and the solidified model can be taken out. At this time, the servo motor 12 is restarted to drive the two first recovery pulleys 13 to rotate. According to the above working principle, it can be seen that the above operation can be repeated to carry out the second round of casting.
