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. 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; 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.

[0003] Chinese Patent (Publication No. CN115647336A), which discloses a casting method and casting device for automotive castings, solves the problem of easy offset of the casting position. It 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 a base, a first connecting block is provided at the bottom of the device body, a first through hole is opened at the top of the casting seat, the first connecting block passes through the first through hole, and the bottom end of the first connecting block is fixedly connected to a 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 clamping plate is provided at the bottom of the shaking block, and first toothed plates are fixedly connected to both sides of the lower clamping plate respectively. Gears are provided on the sides of the two first toothed plates away from each other, and a second toothed plate is provided on the side of the gear away from the first toothed plate; to prevent the position of the device body from shifting and facilitate the external demoulding mechanism to take out the casting.

[0004] According to the above solution, when the above solution is used, the clamping plate moves towards the shaking block and cooperates with the lower clamping plate to clamp the shaking block. At the same time, the limiting cone is inserted into the positioning groove to make the shaking block stable between the two clamping plates, which can prevent the body from shifting. However, the flow rate of the casting alloy liquid injection cannot be controlled, which has limitations. For this reason, we propose a casting device for automotive body panels made of new materials. Summary of the Invention

[0008] As a further improvement of this solution, a servo motor capable of driving the casting punch to move downward is fixedly installed on the outer wall of the installation chassis.

[0009] As a further improvement of this solution, the input mechanism includes a liquid storage pipe filled with liquid water inside.

A liquid passing port is opened at one end of the liquid storage pipe close to the casting die, and the liquid passing port is communicated with the first liquid injection port. An elastic shrinkage plate is slidably connected to the inner wall of the liquid storage pipe.

[0010] As a further improvement of this solution, the top section of the elastic shrinkage plate is fixedly connected with a bent arc arm.

The space between the bottom of the second moving plate and the liquid storage pipe, the inside of the communicating circular pipe and the rubber spiral pipe are all filled with high-pressure gas. A first moving plate is fixedly connected between the two communicating circular pipes. A reset shrinkage pipe is fixedly connected between the first moving plate and the inner wall of the installation chassis. The first moving plate and the casting punch are fixedly connected by two third steel ropes. A first abutting block with a reset function is slidably connected inside the first moving plate.

[0012] As a further improvement of this solution, the adjusting mechanism includes a speed regulating pipe fixedly connected to the outer wall of the liquid storage pipe. A piston block with a reset function is slidably connected to the inner wall of the speed regulating pipe. The piston block is fixedly connected to the bent arc arm through a pushing arm.

Utilizing the liquid damping effect, the alloy liquid fills the mold cavity at a stable and slow speed, effectively avoiding defects such as splashing, turbulence, and bubbles caused by too fast injection speed, and significantly improving the quality and forming accuracy of the casting. 2. When the present invention is used, the elastic shrinkage plate realizes the automatic filling of the casting alloy liquid without manual intervention. This not only reduces the labor input and operation errors, greatly improves the production efficiency, but also avoids the introduction of impurities, bubbles, and alloy liquid splashing by manual operation, ensuring the purity and surface quality of the casting. At the same time, the elastic shrinkage plate can adaptively adjust the filling force and speed to ensure that the alloy liquid flows into the cavity evenly and stably. Description of the Drawings

The rubber ring can enhance the sealing performance between the piston block 48 and the speed control tube 33. A through port 42 is formed in the outer wall of the piston block 48. A first elastic contraction rod 41 is fixedly connected to the inner wall of the through port 42. The output end of the first elastic contraction rod 41 is fixedly connected to a first plugging plate 39. The outer wall of the first plugging plate 39 abuts against the outer wall of the through port 42; A plurality of connecting tubes 46 are fixedly connected to the outer wall of the piston block 48. The plurality of connecting tubes 46 are circumferentially distributed inside the piston block 48. A plurality of water permeable holes are formed at one end of each connecting tube 46 close to the first plugging plate 39. A second contraction rod 45 is fixedly connected to the inner wall of each connecting tube 46. The output end of the second contraction rod 45 is fixedly connected to a third plugging plate 44. The outer wall of the third plugging plate 44 abuts against the outer wall of the connecting tube 46; The bottom of the second moving plate 24 is rotatably connected to a threaded tube 25 through a rotating shaft. The outer wall of the threaded tube 25 is threadedly connected to the interior of the liquid storage tube 17. The bottom of the threaded tube 25 is fixedly connected to a turntable 26. A plurality of weight reduction holes are formed in the outer wall of the turntable 26. The plurality of weight reduction holes are circumferentially distributed on the outer wall of the turntable 26. The bottom of the second moving plate 24 is fixedly connected to a telescopic arm 27 through a connecting plate. One end of the telescopic arm 27 away from the second moving plate 24 is fixedly connected to the bottom of the push arm 29 through a mating telescopic tube 50. When the telescopic arm 27 moves upward, the mating telescopic tube 50 will contract. A connecting rod 31 is rotatably connected to the interior of the piston block 48 through a rotating shaft. A mating torsion spring 43 is clamped between the connecting rod 31 and the piston block 48. The mating torsion spring 43 is in a state of storing energy; The outer wall of the connecting rod 31 is slidably inserted into the interiors of the first elastic contraction rod 41 and the first plug plate 39. A plurality of second plug plates 40 are fixedly connected to the outer wall of the connecting rod 31. The outer wall of each second plug plate 40 is in mutual abutment with the outer wall of the piston block 48. The plurality of second plug plates 40 are circumferentially distributed on the outer wall of the connecting rod 31. The outer wall of the push arm 29 is rotatably connected to a second recovery wire reel 32 through a rotating shaft. A pull rope 28 is wound around the outer wall of the second recovery wire reel 32. The free end of the pull rope 28 is fixedly connected to the telescopic arm 27. One end of the second recovery wire reel 32 close to the speed regulation tube 33 is fixedly connected to a first mating contraction tube 30. The first mating contraction tube 30 is rotatably connected to the speed regulation tube 33. The left end of the connecting rod 31 is fixedly connected to the left end inner wall of the first mating contraction tube 30; Specifically, the casting punch 6 moves closer to and abuts against the casting die 9. The casting punch 6 will pull the first moving plate 18 through the third steel wire rope 14. The first moving plate 18 drives the elastic contraction plate 22 to move through the arc-shaped arm 23. When the elastic contraction plate 22 moves to the right side of the second liquid injection port 36, the casting alloy liquid can be poured into the interior of 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 abutting block 35 will disengage from the outer wall abutment of the first abutting block 34. When replacing the mold, the required capacity of the casting alloy liquid inside the replaced mold is less than that of the original one. Then rotate the turntable 26. The turntable 26 drives the threaded tube 25 to rotate. The threaded tube 25 drives the second moving plate 24 to move upward. When the second moving plate 24 moves upward, it will also drive the elastic contraction plate 22 to contract. When the second moving plate 24 moves upward, the compressed gas between the second moving plate 24 and the liquid storage tube 17 will have a larger space. The molecules of the compressed gas become smaller. At this time, the pressure of the compressed gas becomes smaller. At this time, the gas pressure inside the communicating circular tube 19 and the rubber spiral tube 20 becomes smaller. 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 interior of the liquid storage tube 17 through the second liquid injection port 36, due to the reduction of the pressure inside the rubber spiral tube 20 at this time, the liquid storage tube 17 will pull and extend the rubber spiral tube 20 due to gravity, so that the second abutting block 35 disengages from the abutment with the first abutting block 34, and the amount of the casting alloy liquid poured each time can be reasonably controlled by the action of gravity, avoiding waste of resources caused by pouring too much casting alloy liquid; Moreover, when the second moving plate 24 moves upward, the telescopic arm 27 will release the tension on the pulling rope 28. Note that when the pulling rope 28 moves, it will drive the telescopic arm 27 to extend through the cooperation with the telescopic tube 50, so that the output end of the telescopic arm 27 is always directly below the second recovery wire wheel 32. The connecting rod 31 will rotate back under the action of the cooperating torsion spring 43. The connecting rod 31 drives the first cooperating shrinkage tube 30 and the second recovery wire wheel 32 to rotate back. When the connecting rod 31 rotates, it will also drive the second blocking plate 40 to rotate. When the second blocking plate 40 rotates, it will correspondingly close and block the corresponding water permeable holes. And it should be noted to avoid the second blocking plate 40 closing and blocking all the water permeable holes. Since the second blocking plate 40 will block some of the water permeable holes, when the piston block 48 moves inside the speed regulating tube 33, the speed of the piston block 48 moving inside the speed regulating tube 33 will be reduced. The piston block 48 will drive the curved arc 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 moving plate 24, and effectively control the speed of the casting alloy liquid being pushed out, avoiding the situation that when the casting alloy liquid is less, the pushing speed is too fast, resulting in the generation of bubbles and affecting the casting.

[0033] The working principle of the present invention is as follows: When the present invention is in use, the servo motor 12 is started. The servo motor 12 will drive the two first recovery wire wheels 13 to rotate. When the first recovery wire wheels 13 rotate, they will recover and pull the second steel rope 11. The second steel rope 11 will pull the mounting plate 5 downward. The mounting plate 5 will drive the casting punch 6 and the casting die 9 to merge. At this time, during the downward movement of the mounting plate 5, it will pull the first moving plate 18 through the third steel rope 14. The first moving plate 18 will drive the first abutting block 34 to abut against the outer wall of the second abutting block 35. The second abutting block 35 will drive the elastic shrinkage plate 22 to move through the curved arc arm 23. The elastic shrinkage plate 22 will move upward on the upper ends of the liquid storage tube 17 and the second moving plate 24. When the elastic shrinkage plate 22 moves to the right end of the inner wall of the liquid storage tube 17, at this time the casting punch 6 and the casting die 9 just merge. At this time, the elastic shrinkage plate 22 is on the right side of the second cooperating 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; When the bending arc arm 23 moves, the bending arc arm 23 also pushes the pushing arm 29, and the pushing arm 29 drives the piston block 48 to move. When the piston block 48 moves inside the inner wall of the speed regulating tube 33, at this time, the third plug plate 44 is in contact and closed with the outer wall of the connecting tube 46, while the first plug plate 39 will disengage from the contact with the outer wall of the through port 42. Since the diameter of the through port 42 is large, the liquid water will freely pass through the inside of the through port 42 and will not affect the moving speed of the piston block 48. When the piston block 48 moves, it will also squeeze and store energy in the second spring. When the casting punch 6 and the casting die 9 are combined, at this time, the casting alloy liquid is injected into the inside of the liquid storage tube 17 through the second liquid injection port 36. When the liquid level reaches the inside of the second liquid injection port 36, the electronic valve is closed at this time, effectively preventing the excess casting alloy liquid inside the second liquid injection port 36 from falling into the inner wall of the liquid storage tube 17. At this time, due to gravity, the liquid storage tube 17 will stretch the rubber spiral tube 20. When the first abutting block 34 disengages from the contact with the outer wall of the second abutting block 35, the second spring will drive the piston block 48 to move back. When the piston block 48 moves back, the first plug plate 39 will abut against the inner wall of the through port 42, and the third plug plate 44 will disengage from the contact with the inner wall of the connecting tube 46. Since the water permeable holes are small, the water passing through the water permeable holes affects the moving speed of the piston block 48, and the moving speed of the piston block 48 decreases; The piston block 48 will push the bending arc arm 23 through the pushing arm 29, and the bending arc arm 23 drives the elastic contraction plate 22 to move back. The elastic contraction plate 22 will discharge the internal casting alloy liquid through the liquid storage tube 17 into the first liquid injection port 15. The casting alloy liquid then enters the casting groove 8 through the first liquid injection port 15. At this time, when the casting alloy liquid enters the casting groove 8, the gas will be discharged through the exhaust port 21. When the casting alloy liquid is drained, the cooling water enters the cavity through the drain pipe. The cooling water will cool the casting alloy liquid. When the casting alloy liquid solidifies, at this time, the servo motor 12 drives the two first recovery wire wheels 13 to rotate back. The first recovery wire wheels 13 will release the second steel rope 11. 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. The reset shrinkage tube 49 loses the tension of the third steel rope 14. The reset shrinkage tube 49 drives the first moving plate 18 to reset. The reset of the first moving plate 18 drives the first abutting block 34 to move. When the bottom of the first abutting block 34 abuts against the upper end of the second abutting block 35, the first abutting block 34 will contract into the first moving plate 18. When the first abutting block 34 disengages from the contact with the second abutting block 35, the plane between the first abutting block 34 and the second abutting block 35 will abut against each other; Note that when the liquid storage tube 17 is under the action of gravity, it will move downward. Even if the liquid storage tube 17 moves downward, the liquid passing port 16 and the first liquid injection port 15 are still connected because the diameters of the first liquid injection port 15 and the liquid passing port 16 are large enough. When the liquid storage tube 17 moves, the first liquid injection port 15 and the liquid passing port 16 are still connected. When the liquid storage tube 17 moves downward under the action of gravity, all the forces are supported by the reset contraction tube 49 through the first moving plate 18 and the rubber spiral tube 20; After the casting alloy liquid cools and solidifies, the servo motor 12 drives the two first recovery wire wheels 13 to rotate in the opposite direction, and the second steel rope 11 will be released. At this time, the third spring 4 releases its stored energy 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, restart the servo motor 12 to drive the two first recovery wire wheels 13 to rotate. According to the above working principle, repeating the above operation can perform the second round of casting.
