DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an aluminum alloy safety buckle vacuum casting device.

[0021] See also Figure 1-Figure 10 A vacuum casting device for an aluminum alloy safety buckle includes a device body 1, a vacuum chamber 2, a feeding mechanism 3 and a collecting chamber 7. The vacuum chamber 2 is fixedly installed inside the device body 1, the feeding mechanism 3 is arranged on the vacuum chamber 2, the collecting chamber 7 is fixedly connected to the bottom of the vacuum chamber 2, a fixed module 6 is fixedly installed on one side of the vacuum chamber 2, and a pushing mechanism 4 and a movable module 5 are arranged on the other side of the vacuum chamber 2. The pushing mechanism 4 is used to drive the movable module 5 to move so as to realize the closing and opening of the movable module 5 and the fixed module 6; The movable module 5 includes a suction mechanism 53, and the fixed module 6 includes a casting groove 62. The feeding mechanism 3 is used to inject aluminum alloy solution into the movable module 5 and the fixed module 6 when the mold is closed. During the process of injecting the aluminum alloy solution, the pushing mechanism 4 can also drive the suction mechanism 53 to move to assist the aluminum alloy solution to fill the inside of the casting groove 62. After solidification, the aluminum alloy solution inside the movable module 5 and the fixed module 6 forms an aluminum alloy safety buckle with uniform texture. After the mold is opened, the formed aluminum alloy safety buckle enters the collection bin 7.

[0022] During operation, the interior of the vacuum chamber 2 is first evacuated, and the push mechanism 4 drives the movable module 5 to move. After the movable module 5 moves, it can be molded with the fixed module 6. After the movable module 5 and the fixed module 6 are molded, the feeding mechanism 3 injects aluminum alloy solution into the movable module 5 and the fixed module 6, and the push mechanism 4 continues to extend during the injection of the aluminum alloy solution. The push mechanism 4 continues to extend and drives the suction mechanism 53 to move. The suction mechanism 53 can actively suck the aluminum alloy solution between the movable module 5 and the fixed module 6 during the movement, and then wait for the movable module 5 and the fixed module 6 to move. The aluminum alloy solution inside the module 6 solidifies. After the aluminum alloy solution solidifies, the pushing mechanism 4 shortens. The shortening of the pushing mechanism 4 drives the movable module 5 and the fixed module 6 to separate and drives the suction mechanism 53 to move inward. After the movable module 5 and the fixed module 6 are separated, the formed aluminum alloy safety buckle enters the collecting bin 7. During the casting process, the aluminum alloy solution is actively sucked into the movable module 5 and the fixed module 6 through the movement of the suction mechanism 53, so that the aluminum alloy solution can fully enter the movable module 5 and the fixed module 6, thereby effectively preventing casting quality problems caused by insufficient injection of the aluminum alloy solution.

[0023] The difference from the above embodiment is that, please refer to Figure 3-Figure 9The feeding mechanism 3 includes a storage bin 31 and a feeding cylinder 34. The storage bin 31 is fixedly installed on the top of the vacuum bin 2. A feeding pipe 32 is fixedly connected to the bottom of the storage bin 31. A feeding port 33 is provided on the outside of the feeding pipe 32. The cylinder body of the feeding cylinder 34 is located at the top of the outside of the storage bin 31 (not shown in the drawings). The movable end of the feeding cylinder 34 slides through the top wall of the storage bin 31 and extends to the inside of the feeding pipe 32. A partition block 35 is fixedly installed on the movable end of the feeding cylinder 34. The outside of the feeding pipe 32 is fixedly connected to one side of the fixed module 6 , and a plurality of feeding ports 33 are equidistantly arranged on both sides of the feeding pipe 32 .

[0024] The bottom of the storage bin 31 is connected to the interior of the vacuum chamber 2 through the feeding pipe 32. The aluminum alloy solution inside the storage bin 31 can be injected into the movable module 5 and the fixed module 6 through the feeding pipe 32. The outside of the partition block 35 fits with the inside of the feeding pipe 32. The extension and contraction of the feeding cylinder 34 can drive the partition block 35 to slide in the feeding pipe 32. The partition block 35 is driven by the feeding cylinder 34 to slide in the feeding pipe 32. When the partition block 35 slides to the connection between the storage bin 31 and the feeding pipe 32, the storage bin 31 and the feeding pipe 32 can be separated. When the partition block 35 slides to the bottom of the feeding pipe 32, the storage bin 31 and the feeding pipe 21 remain connected. The aluminum alloy solution inside the storage bin 31 can enter the feeding pipe 32 and enter between the movable module 5 and the fixed module 6 from each feeding port 33.

[0025] When the feeding cylinder 34 is extended during the casting process, the dividing block 35 slides to the bottom of the feeding pipe 32, so that the aluminum alloy solution can flow from the upper storage bin 31 into the lower feeding pipe 32. After the aluminum alloy solution enters the feeding pipe 32, it can enter the movable module 5 and the fixed module 6 from the feeding port 33. After the injection is completed, the feeding cylinder 34 is shortened, and the dividing block 35 is driven by the feeding cylinder 34 to move upward. When the dividing block 35 moves to the connection between the storage bin 31 and the feeding pipe 32, the storage bin 31 and the feeding pipe 32 can be separated. In addition, during the movement of the dividing block 35, the excess aluminum alloy solution can be recovered into the storage bin 31. The dividing block 35 is driven to move inside the feeding pipe 32 by the extension and contraction of the feeding cylinder 34, thereby separating and connecting the feeding pipe 32 and the storage bin 31.

[0026] The difference from the above embodiment is that, please refer to Figure 4-Figure 6The pushing mechanism 4 includes a pushing turntable 41 and a pushing base 47. The pushing turntable 41 is rotatably mounted on the side of the movable module 5. The pushing base 47 is fixedly mounted on the inner wall of the vacuum chamber 2. A pushing cylinder 42 is arranged on one side of the pushing turntable 41. A buffer spring 46 is fixedly connected between the cylinder body of the pushing cylinder 42 and the pushing base 47. The movable end of the pushing cylinder 42 is rotatably matched with the surface of the pushing turntable 41. A pushing transmission rod 45 is fixedly connected to one side of the pushing turntable 41. A connecting tube 43 is fixedly connected to the outside of the cylinder body of the pushing cylinder 42. A steering groove 44 is provided on the outside of the connecting tube 43. A turntable fixing block 48 is fixedly mounted on one side of the pushing turntable 41. One side of the push turntable 41 is rotatably connected to the movable module 5 , and the other side of the push turntable 41 is installed with a push cylinder 42 , a push transmission rod 45 and a turntable fixing block 48 .

[0027] One end of the push transmission rod 45 is fixedly connected to the push turntable 41, and the other end of the push transmission rod 45 is slidably assembled inside the steering groove 44. Two turntable fixing blocks 48 are installed on the push turntable 41, and the two turntable fixing blocks 48 are installed at the edge of the side of the push turntable 41; When the movable end of the pushing cylinder 42 is extended or retracted, one end of the pushing transmission rod 45 can move along the steering groove 44. The steering groove 44 is divided into a horizontal section and an arc section. When one end of the pushing transmission rod 45 is located in the horizontal section of the steering groove 44, the extension and retraction of the movable end of the pushing cylinder 42 can drive the pushing turntable 41 and the movable module 5 to move in the horizontal direction to approach or move away from the fixed module 6 to achieve mold closing or mold opening; when one end of the pushing transmission rod 45 is located in the arc section of the steering groove 44, the movable module 5 and the fixed module 6 are in a mold closing state, and the extension and retraction of the movable end of the pushing cylinder 42 can no longer drive the pushing turntable 41 and the movable module 5 to move in the horizontal direction, but drives the pushing turntable 41 to rotate on the movable module 5, and adapts to the horizontal movement distance of the movable end of the pushing cylinder 42 through the elastic deformation of the buffer spring 46.

[0028] During operation, the push cylinder 42 is extended to drive the movable module 5 and the fixed module 6 to close the mold. At this time, the push transmission rod 45 moves along the horizontal section of the steering groove 44. After the movable module 5 and the fixed module 6 are closed, the push cylinder 42 continues to extend. When the push cylinder 42 continues to extend, the buffer spring 46 shortens, and the connecting tube 43 moves toward the push base 47. During the continuous extension of the push cylinder 42, the push transmission rod 45 moves along the arc section of the steering groove 44. During the movement of the push transmission rod 45, the push turntable 41 can also be driven to rotate on the movable module 5. When the push turntable 41 rotates, the turntable fixing block 48 can be driven to rotate clockwise. When the turntable fixing block 48 rotates, the suction mechanism 53 can be driven to move outward to assist in the injection of the aluminum alloy solution. When the push cylinder 42 is put into operation, the push cylinder 42 is shortened after the casting is completed. During the shortening process of the push cylinder 42, the buffer spring 46 rebounds, the movable module 5 and the fixed module 6 are separated, and the push transmission rod 45 continues to move along the steering groove 44 when the push transmission rod 45 moves along the arc section of the steering groove 44, and can drive the push turntable 41 to rotate counterclockwise, and when the push turntable 41 rotates counterclockwise, it can drive the partition block 35 to move inward, and the movable module 5 and the partition block 35 are driven to assist in casting by the extension and shortening of the push cylinder 42, and the buffering between the push cylinder 42 and the push base 47 through the buffer spring 46 can make the connection between the movable module 5 and the fixed module 6 tighter, thereby significantly improving the casting quality.

[0029] The difference from the above embodiment is that, please refer to Figure 5-Figure 8 The movable module 5 also includes a movable mold body 51, a suction mechanism 53 is arranged on one side of the movable mold body 51, one side of the movable mold body 51 is rotatably connected to the push turntable 41, and a feeding pipe groove 52 is opened on the other side of the movable mold body 51. When the movable module 5 moves to close the mold with the fixed module 6, the inner wall of the feeding pipe groove 52 can fit the outer wall of the feeding pipe 32, and a suction integration plate 54 is arranged on one side of the suction mechanism 53. The other end of the suction integration plate 54 is fixedly installed with an integration plate moving circle 55, and the integration plate moving circle 55 is sleeved on the outside of the turntable fixed block 48; When the push turntable 41 drives the turntable fixing block 48 to rotate, it can drive the suction integration plate 54 to move through the integration plate moving circle 55. When the suction integration plate 54 moves horizontally, it can drive the suction mechanism 53 to move synchronously.

[0030] The material suction mechanism 53 includes a material suction block body 531, the outside of the material suction block body 531 is fixedly connected to the material suction integration plate 54, the top of the material suction block body 531 is in contact with the movable mold body 51, a sleeve fixing block 532 is fixedly installed on the bottom of the material suction block body 531, both sides of the sleeve fixing block 532 are fixedly connected to a material suction spring cylinder 533, the ends of the material suction spring cylinder 533 are fixedly connected to a material suction block spring 534, the movable ends of the material suction block spring 534 are fixedly connected to a material suction block connecting rod 535, and the ends of the material suction block connecting rod 535 are fixedly connected to a material suction telescopic block 536; The suction telescopic blocks 536 are located on both sides of the suction block body 531 when the suction block spring 534 is in a natural state. The suction telescopic blocks 536 can be retracted into the suction block body 531 when squeezed.

[0031] When working, the pushing mechanism 4 can drive the movable mold body 51 to move and close the mold with the fixed mold group 6, and when the pushing turntable 41 drives the turntable fixed block 48 to rotate, it can drive the suction integration plate 54 to move through the integration plate moving circle 55, and when the suction integration plate 54 moves horizontally, it can drive the suction mechanism 53 to move synchronously. After the mold is closed, the suction mechanism 53 fits the inside of the casting groove 62, and the suction mechanism 53 moves horizontally during the casting process. When the suction mechanism 53 moves horizontally, the aluminum alloy solution is sucked into the inside of the casting groove 62, and when the suction mechanism 53 continues to move outward, it is squeezed by the inner wall of the casting groove 62, and the suction mechanism 53 is sucked. The telescopic block 536 is retracted into the interior of the suction block body 531, so that the aluminum alloy solution can completely fill the interior of the casting groove 62. After the casting is completed, the movable module 5 and the fixed module 6 are separated. After the movable module 5 and the fixed module 6 are separated, the suction telescopic block 536 is driven by the suction block spring 534 to pop out from the interior of the suction block body 531. When the pushing mechanism 4 drives the movable module 5 to perform mold casting, it can also drive the suction mechanism 53 to suck the aluminum alloy solution, which can better fill the interior of the casting groove 62 during the pouring of the aluminum alloy solution, thereby preventing uneven product texture during the casting process.

[0032] The difference from the above embodiment is that, please refer to Figure 9-10 The fixed mold assembly 6 also includes a fixed mold body 61, a casting groove 62 is provided inside the fixed mold body 61, a telescopic groove 63 is provided inside the casting groove 62, the bottom of the telescopic groove 63 is fixedly connected to one end of a telescopic block spring 64, and the other end of the telescopic block spring 64 is fixedly connected to a casting telescopic block 65; Multiple groups of casting grooves 62 are evenly arranged on both sides of the interior of the fixed mold body 61. Each group of casting grooves 62 is provided with a telescopic groove 63. The casting groove 62 is wider at one end close to the feeding pipe 32 and is a narrower rectangular groove at the other end away from the feeding pipe 32.

[0033] The casting telescopic block 65 is movably installed inside the telescopic slot 63 through the telescopic block spring 64, and the position of the casting slot 62 corresponds to the position of the suction mechanism 53; When the movable module 5 and the fixed module 6 are closed, the suction mechanism 53 is embedded in the interior of the casting groove 62, and the casting telescopic block 65 is retracted into the interior of the telescopic groove 63 under the extrusion of the suction mechanism 53. When the suction mechanism 53 moves, the molten aluminum alloy solution can be drawn into the interior of the casting groove 62. When the suction mechanism 53 moves to the outermost side, the casting telescopic block 65 moves upward driven by the telescopic block spring 64 and then squeezes the excess aluminum alloy solution into the interior of the feeding pipe 32.

[0034] When the movable module 5 and the fixed module 6 are in the mold opening state, the suction block spring 534 is in a natural state, the suction telescopic blocks 536 are located on both sides of the suction body 531, and the positions of each suction mechanism 53 correspond to 65. When the push cylinder 42 is extended, the movable module 5 can be pushed to approach the fixed module 6 for mold closing. At this time, each casting telescopic block 65 is retracted into the inside of the telescopic groove 63 under the extrusion of the suction mechanism 53, and the suction connecting block 536 is adapted and attached to the outer shape of the wider end of the casting groove 62. After mold closing, the push cylinder 42 continues to extend, and the push turntable 41 rotates. When the push turntable 41 rotates, the suction integration plate 54 can be driven to move through the turntable fixed block 48. When the suction integration plate 54 moves, it can drive the suction mechanism 53 to move in the direction away from 32, so that the movable module 5 and the fixed module 6 are spaced apart. The formed mold cavity is gradually emptied, and when the suction mechanism 53 moves, the molten aluminum alloy solution flows from the inside of the feed pipe 32 into the internal mold cavity of the casting trough 62. During the movement of the suction mechanism 53, the end of the suction connecting block 536 maintains a sliding fit with the side wall of the casting trough 62. When the suction mechanism 53 moves to a narrower part of the casting trough 62, the suction connecting block 536 shrinks into the inside of the suction body 531, and then the suction mechanism 53 continues to move outward for a distance, and the casting telescopic block 65 no longer contacts the suction mechanism 53. At this time, the shape of the mold cavity is complete, and the casting telescopic block 65 moves upward under the drive of the telescopic block spring 64 and then squeezes the excess aluminum alloy solution into the inside of the feed pipe 32. By filling the casting trough 62 with aluminum alloy solution and then raising the casting telescopic block 65, uneven casting at the corners of the safety buckle can be effectively prevented.

[0035] While embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
