[0017] The present invention provides a vibrating compaction device with uniform density for casting molding, which has the following beneficial effects: 1. The casting molding uses a vibrating compaction device with uniform density. The strip striking piece and the toggle tooth rotate together with the rotating shaft, so that the rotating strip striking piece can be used to contact the flat elastic sheet, so that the flat elastic sheet is struck and vibrates, and a closed space is formed between the rectangular cavity and the flat elastic sheet, so that the air in the rectangular cavity will be impacted and vibrate.

[0020] Fourth, the casting mold uses a vibrating compaction device with uniform density. As the movable module moves downward, the movable module will drive the connecting guide bar to move downward together. The connecting guide bar can be inserted into the inside of the bar groove to limit the connecting guide bar. With the support of the connecting guide bar on the movable module, the movable module moves more smoothly and is less likely to shake.
[0021] 5. The casting mold uses a vibrating compaction device with uniform density. When the bottom end of the connecting guide bar moves downward along the bar-shaped groove, the bottom end of the connecting guide bar contacts the bottom of the inner side surface of the hook-shaped tooth. As the connecting guide bar continues to move downward, the bottom of the inner side surface of the hook-shaped tooth is subjected to pressing pressure, which can make the hook-shaped tooth rotate clockwise, so that the engaging groove is stuck on the outside of the connecting guide bar, so that the connecting guide bar can be positioned, making it difficult for the connecting guide bar to deviate.
[0022] 6. The casting mold uses a vibration compaction device with uniform density. When the movable module and the fixed module are molded together, the telescopic end of the hydraulic cylinder is used to apply pressing pressure to the movable module, so that the movable module and the fixed module can be compacted, and the bottom end of the connecting guide bar is moved to the bottom, and the bottom of the inner side of the hook-shaped tooth is pressed through the bottom end of the connecting guide bar, so that the card groove is in a vertical state, so that self-locking can be formed between the structures.
[0023] 7. The casting mold uses a vibrating and compacting device with uniform density. The end of the toggle tooth is in contact with the pressure plate. As the toggle tooth rotates, the pressure plate can be pressed by the end of the toggle tooth, so that the arc support tube drives the knocking link to rotate clockwise, and the ball is away from the bottom of the fixed module. The reset spring bar is squeezed and deformed, and the end of the toggle tooth is separated from the pressure plate, so that the pressing force on the pressure plate disappears, and under the elastic force provided by the reset spring bar, the arc support tube drives the knocking link to rotate counterclockwise for reset, so that the ball can knock and vibrate the side of the bottom of the fixed module.

The telescopic end of the hydraulic cylinder 61 passes through the top of the connecting plate 3 and extends to its bottom. A movable module 62 is fixedly installed at the telescopic end of the hydraulic cylinder 61 and close to the fixed module 41. A gate sleeve 63 is installed in the middle of the top of the movable module 62. A connecting guide strip 64 is fixedly installed on the side of the outer side of the movable module 62, and the connecting guide strip 64 is installed close to the bar groove 43. The staff turns on the hydraulic cylinder 61 to work. The movable module 62 can be driven to move downward and upward by the extension and contraction of the telescopic end of the hydraulic cylinder 61, thereby adjusting the position of the movable module 62 to facilitate the closing and opening of the mold between the movable module 62 and the fixed module 41.

With the support of the connecting guide bar 64 on the movable module 62, the movable module 62 can move more smoothly and is less likely to shake.
[0030] The position of the moving module 62 corresponds to the position of the fixed module 41 , and the connecting guide bar 64 is installed just above the strip groove 43 .

A clamping groove 447 is provided at the position of the pressure plate 446 and the hook-shaped tooth 441 and near the strip groove 43. A compression spring 448 is fixedly installed between the bottom of the inner cavity of the arc-shaped support tube 442 and the bottom end of the knocking connecting rod 444. When the bottom end of the connecting guide bar 64 moves downward along the strip groove 43, the bottom end of the connecting guide bar 64 contacts the bottom of the inner side surface of the hook-shaped tooth 441. As the connecting guide bar 64 continues to move downward, the bottom of the inner side surface of the hook-shaped tooth 441 is subjected to pressing pressure, which can make the hook-shaped tooth 441 rotate clockwise, so that the clamping groove 447 is stuck on the outer side of the connecting guide bar 64, so that the connecting guide bar 64 can be positioned, making it less likely for the connecting guide bar 64 to be offset.
[0033] The hook-shaped teeth 441 are installed at an angle, the position of the engaging groove 447 corresponds to the position of the strip-shaped groove 43 , and the reset spring bar 443 is semicircular.
[0034] The sphere 445 is installed directly below the fixed module 41, the pressure plate 446 is installed at an angle, and the pressure plate 446 is installed directly below the toggle tooth 55, the pressure spring 448 and the knock link 444 pass through the inside of the arc-shaped support tube 442, when the moving module 62 and the fixed module 41 are molded together, and the telescopic end of the hydraulic cylinder 61 is used to apply pressing pressure to the moving module 62, the moving module 62 and the fixed module 41 can be compacted, and the bottom end of the connecting guide bar 64 is moved to the bottom, and the bottom of the inner side of the hook-shaped tooth 441 is pressed through the bottom end of the connecting guide bar 64, so that the card slot 447 is in a vertical state, so that self-locking can be formed between the structures.
[0035] The third embodiment is based on the first and second embodiments. Figures 1 to 8 As shown: A vibration mechanism 5, which is used to knock the bottom of the fixed module 41, and the vibration mechanism 5 is installed at the bottom of the fixed module 41; The vibration mechanism 5 includes a base 51 and a transmission 52. The base 51 is installed at the side of the bottom of the fixed module 41. The transmission 52 is installed at the bottom of the fixed module 41 and away from the side of the base 51. A rotating shaft 53 is rotatably installed between the base 51 and the transmission 52. A strip-shaped striking piece 54 is fixedly installed on the outer cylindrical surface of the rotating shaft 53 and close to the flat elastic sheet 46. A shifting tooth 55 is fixedly installed at one end of the rotating shaft 53 away from the transmission 52. A servo motor 56 is installed in the middle of the outer side of the transmission 52. The output end of the servo motor 56 is installed with the rotating shaft 53 through the transmission 52. The staff turns on the servo motor 56 to work, and uses the rotation of the output end of the servo motor 56 to Under the transmission connection of the transmission 52, the rotating shaft 53 can be driven to rotate, so that the strip striking piece 54 and the driving tooth 55 rotate together with the rotating shaft 53, and the rotating strip striking piece 54 can be utilized to contact the flat elastic sheet 46, so that the flat elastic sheet 46 is struck and vibrates, and a closed space is formed between the rectangular cavity 45 and the flat elastic sheet 46, so that the air in the rectangular cavity 45 will be impacted and vibrate, and the air column in the hollow part is equivalent to a resonance chamber, which can increase the vibration frequency, promote the bottom vibration of the fixed module 41, and help to evenly distribute the liquid material in the cavity 42. Under the action of vibration, the air in the liquid material is helped to be discharged, and air holes are not easy to appear.
[0036] The strip striking piece 54 is made of rubber. When the strip striking piece 54 strikes the bottom of the flat elastic sheet 46, the strip striking piece 54 will be deformed, so that the rotating shaft 53 can drive the strip striking piece 54 to rotate continuously. The strip striking piece 54 rotates smoothly as a whole, and the mechanism is not prone to getting stuck. In addition, there is a flexible contact between the strip striking piece 54 and the flat elastic sheet 46 to avoid rigid contact, so the bottom of the flat elastic sheet 46 can be protected and is not prone to damage.
[0037] The rotating shaft 53 is installed directly below the fixed module 41, and the toggle tooth 55 is installed on the side close to the strip groove 43. There are two rotating shafts 53, and the two rotating shafts 53 are symmetrically installed along the rectangular cavity 45. When the rotating shaft 53 drives the toggle tooth 55 to rotate in a circle, the end of the toggle tooth 55 is used to contact the pressure plate 446. As the toggle tooth 55 rotates, the end of the toggle tooth 55 can press the pressure plate 446, so that the arc support tube 442 is brought into contact with the pressure plate 446. The movable knocking link 444 rotates clockwise, the ball 445 moves away from the bottom of the fixed module 41, and the reset spring bar 443 is squeezed and deformed, and the end of the toggle tooth 55 is separated from the pressure plate 446, so that the pressing force on the pressure plate 446 disappears, and under the elastic force provided by the reset spring bar 443, the arc support tube 442 drives the knocking link 444 to rotate counterclockwise for reset, so that the ball 445 can knock and vibrate the side of the bottom of the fixed module 41.
[0038] When in use, the staff first turns on the hydraulic cylinder 61 to work, and the movable module 62 can be driven to move downward by the extension of the telescopic end of the hydraulic cylinder 61; As the moving module 62 moves downward, the moving module 62 drives the connecting guide bar 64 to move downward together, and the connecting guide bar 64 can be inserted into the inner part of the bar-shaped groove 43 to limit the connecting guide bar 64. With the support of the connecting guide bar 64 on the moving module 62, the moving module 62 moves more smoothly and is not prone to shaking. By continuously moving the movable module 62 downward, the position of the movable module 62 is adjusted, so that the movable module 62 and the fixed module 41 can be molded together; At the same time, the telescopic end of the hydraulic cylinder 61 is used to apply a pressing force to the movable module 62, so that the movable module 62 and the fixed module 41 can be compacted, and the bottom end of the connecting guide bar 64 is moved to the bottom, and the bottom of the inner side of the hook-shaped tooth 441 is pressed by the bottom end of the connecting guide bar 64, so that the clamping groove 447 is in a vertical state, so that the structures can be self-locking; At this time, the staff pours the liquid material from the sprue sleeve 63 into the cavity 42, and starts the servo motor 56 to work. By using the rotation of the output end of the servo motor 56 and the transmission connection of the transmission 52, the rotating shaft 53 can be driven to rotate, so that the strip-shaped striking member 54 and the shifting tooth 55 rotate together with the rotating shaft 53, and the rotating strip-shaped striking member 54 can be used to contact the plane elastic sheet 46, so that the plane elastic sheet 46 is struck and vibrates, and the rectangular cavity 45 and the plane elastic sheet 46 form a closed space, so that the air in the rectangular cavity 45 will be impacted and vibrate, and the air column in the hollow part is equivalent to a resonance chamber, which can increase the vibration frequency, promote the bottom vibration of the fixed module 41, and help the liquid material in the cavity 42 to be evenly distributed. Under the action of vibration, it helps to discharge the air in the liquid material, and it is not easy to have air holes; The strip-shaped striking member 54 is made of rubber. When the strip-shaped striking member 54 strikes the bottom of the planar elastic sheet 46, the strip-shaped striking member 54 will be deformed, so that the rotating shaft 53 can drive the strip-shaped striking member 54 to rotate continuously. The strip-shaped striking member 54 rotates smoothly as a whole, and the mechanism is not likely to get stuck. Moreover, the strip-shaped striking member 54 and the planar elastic sheet 46 are in flexible contact, avoiding rigid contact, and the bottom of the planar elastic sheet 46 can be protected and is not likely to be damaged. When the rotating shaft 53 drives the toggle tooth 55 to rotate in a circle, the end of the toggle tooth 55 contacts the pressure plate 446. As the toggle tooth 55 rotates, the pressure plate 446 can be pressed by the end of the toggle tooth 55, so that the arc support tube 442 drives the knocking link 444 to rotate clockwise, and the ball 445 is away from the bottom of the fixed module 41. The reset spring bar 443 is squeezed and deformed, and the end of the toggle tooth 55 is separated from the pressure plate 446, so that the pressing force on the pressure plate 446 disappears, and under the elastic force provided by the reset spring bar 443, the arc support tube 442 drives the knocking link 444 to rotate counterclockwise for reset, so that the ball 445 can knock and compact the side of the bottom of the fixed module 41. When the liquid material is poured into the cavity 42, the movable module 62 and the fixed module 41 can be pressurized and cooled until the casting of the parts is completed, and the hydraulic cylinder 61 is started again to work. By utilizing the contraction of the telescopic end of the hydraulic cylinder 61, an upward pulling force can be applied to the movable module 62, so that the mold can be opened and the parts can be taken out.
