DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-8 , further details of this application are given.

[0028] Example:

[0029] The present application embodiment discloses a vibrating table for lost foam casting. Figure 1 A vibrating table for lost foam casting comprises a vibrating table body 1, a limiting mechanism 2 for limiting the position of a sand box is arranged on the vibrating table body 1, and side impact mechanisms 3 for impacting the two sides of the sand box are arranged on both sides of the vibrating table body 1.

[0030] Reference Figure 1-2The limiting mechanism 2 includes a vertical limiting assembly 21 for pressing the sand box and a horizontal limiting assembly 22 for limiting the bottom of the sand box in the horizontal direction. The horizontal limiting assembly 22 includes four limiting corner blocks 221 adapted to the corner ends of the sand box, and the limiting corner blocks 221 are slidably connected to the vibration table body 1. The vibration table body 1 is provided with a second driving mechanism 23 for driving the four limiting corner blocks 221 to simultaneously retract or expand. When the sand box to be compacted moves toward the compaction table body 1, the four limiting corner blocks 221 are in a scattered state, and the distance between two adjacent limiting corner blocks 221 is large, so that the sand box to be compacted can pass between the two limiting corner blocks 221; when the sand box moves to the center of the compaction table body 1, the second driving mechanism 23 is started, driving the four limiting corner blocks 221 to move inward at the same time, until the limiting corner blocks 221 abut against the bottom corner ends of the adjacent corresponding sand boxes, so as to limit the horizontal direction of the sand box, and further reduce the possibility of relative displacement between the sand box and the compaction table body 1 during vibration. After compaction is completed, the second driving mechanism 23 is started, driving the four limiting corner blocks 221 to disperse outward at the same time, so as to facilitate the sand box to move out of the compaction table body 1.

[0031] Reference Figure 2-3 The second driving mechanism 23 includes two symmetrically arranged driving plates 231, which are arranged along the width direction of the vibration table body 1. The driving plates 231 are slidably arranged inside the vibration table body 1 along the length direction of the vibration table body 1, and a receiving space 11 for accommodating the driving plates 231 is provided in the vibration table body 1. A diagonal guide groove 12 corresponding to the limiting angle block 221 is provided on the table surface of the vibration table body 1, and the diagonal guide groove 12 is connected with the receiving space 11. A moving rod 222 is penetrated in the diagonal guide groove 12, and the bottom end of the moving rod 222 is slidably connected with the corresponding driving plate 231 along the length direction of the driving plate 231, and the top end of the moving rod 222 is fixed to the bottom center of the corresponding limiting angle block 221. The length direction of the diagonal guide groove 12 is the same as the diagonal connecting direction of the four limiting angle blocks 221, and a driving component 4 for driving the driving plates 231 to move toward each other or away from each other is provided in the receiving space 11. When the driving assembly 4 drives the driving plate 231 to approach each other, the driving plate 231 drives the moving rods 222 on both sides of the driving assembly 4 to approach each other, and through the guiding effect of the diagonal guide groove 12, the moving rods 222 gradually move closer and shrink along the length direction of the diagonal guide groove 12; when the driving assembly 4 drives the driving plate 231 to move away from each other, the driving plate 231 drives the moving rods 222 on both sides of the driving assembly 4 to move away from each other, and through the guiding effect of the diagonal guide groove 12, the moving rods 222 gradually expand outwards and move away from each other along the length direction of the diagonal guide groove 12, thereby achieving the purpose of driving the four limiting corner blocks 221 to shrink inwards or expand outwards at the same time.

[0032] Reference Figure 2-4The driving assembly 4 includes a driving motor 41 and a driving bevel gear 42 disposed in the accommodating space 11. The driving bevel gear 42 and the output end of the driving motor 41 are coaxially fixed, and the driving bevel gear 42 is simultaneously meshed with two oppositely disposed driven bevel gears 43. A stud 44 is coaxially fixed to the large end of the driven bevel gear 43. The stud 44 is rotatably disposed in the accommodating space 11 along the length direction of the vibration table body 1, and a threaded sleeve 45 is threadedly connected to one end of the stud 44 away from the driven bevel gear 43. A slider 451 is fixed to the upper end of the threaded sleeve 45, and the slider 451 is slidably connected to the inner wall of the accommodating space 11. The end of the threaded sleeve 45 away from the stud 44 is connected to the center of one side of the adjacent driving plate 231. When the driving motor 41 rotates, it drives the active bevel gear 42 to rotate, and the rotation of the active bevel gear 42 drives the two driven bevel gears 43 to rotate, and the rotation of the two driven bevel gears 43 respectively drives the corresponding studs 44 to rotate, and the rotation of the studs 44 drives the threaded sleeve 45 to move along the length direction of the compaction table body 1, so that the purpose of driving the driving plates 231 to move toward each other or away from each other is achieved through one driving source, and then the purpose of driving the four limiting angle blocks 221 to complete the inward contraction and outward expansion is achieved through one driving source, which saves the number of driving sources installed, improves energy efficiency, and ensures the synchronization rate of the movement of the four limiting angle blocks 221, so that the four limiting angle blocks 221 are clamped in place at the same time.

[0033] Reference Figure 3-4 In order to reduce the possibility of dust on the drive assembly 4 and extend the service life of the drive assembly 4, a dust cover 111 is installed in the accommodating space 11. The drive motor 41, the active bevel gear 42 and the driven bevel gear 43 are all located in the dust cover 111. The dust cover 111 is provided with an escape hole 1111 for the threaded sleeve 45 to pass through, and a part of the threaded sleeve 45 is always located in the dust cover 111 during the movement process.

[0034] Reference Figure 2 , the bottom wall of the accommodating space 11 is inclined, a certain distance is left between the bottom wall of the driving plate 231 and the bottom wall of the accommodating space 11, and a cleaning port 13 connected to the accommodating space 11 is provided on one side of the vibration table body 1, and the cleaning port 13 is arranged at the inclined lower end of the bottom wall of the accommodating space 11, and the lower end of the cleaning port 13 is not higher than the inclined lower end of the bottom wall of the accommodating space 11. In this way, the dust generated in the production workshop enters the accommodating space 11 through the diagonal guide groove 12, slides down along the bottom wall of the accommodating space 11, and is finally discharged from the cleaning port 13, reducing the possibility of dust accumulation in the accommodating space 11 and ensuring that the driving plate 231 can move smoothly.

[0035] Reference Figure 1The vertical limit assembly 21 includes a plurality of fixed frames 211 welded on the side wall of the vibration table body 1 and a connecting rod 212 rotatably connected to the fixed frame 211. The lower fixed rod of the end of the connecting rod 212 close to the vibration table body 1 has a clamping block 213, and the lower end of the connecting rod 212 away from the clamping block 213 is fixed with a lifting rod 214. A lifting driving member 215 for driving the lifting rod 214 to rise and fall is installed on the fixed frame 211. In this embodiment, the lifting driving member 215 is a cylinder. When the lifting driving member 215 starts to drive the lifting rod 214 to rise, the connecting rod 212 rotates, driving the clamping block 213 to move downward until the clamping block 213 is pressed against the top of the sand box, thereby pressing the sand box to achieve the limiting effect in the vertical direction, thereby ensuring the vibration effect of the molding sand.

[0036] Reference Figure 1 and Figure 5 The side-impact mechanism 3 includes a vertically arranged main rod 31 and a plurality of side-impacting members 32 arranged on the side of the main rod 31 close to the table surface of the vibration table body 1. The vibration table body 1 is provided with a driving module 5 for driving the main rod 31 to move back and forth toward or away from the sand box. When in use, the sand box is fixed on the table surface of the vibration table body 1 through the limiting mechanism 2, and the table surface of the vibration table body 1 vibrates, thereby vibrating the molding sand in the sand box; at the same time, the driving module 5 drives the main rod 31 to move back and forth toward or away from the sand box, and the movement of the main rod 31 drives the side-impacting members 32 to move, so that the side-impacting members 32 hit the side wall of the sand box back and forth, so that the sand box further vibrates in the lateral direction, and then the molding sand in the sand box is further vibrated and compacted, which is conducive to improving the vibration effect.

[0037] Reference Figure 5 The side-strike member 32 includes a telescopic rod 321 and a side-strike ball 322. One end of the telescopic rod 321 is fixed to the outer wall of the main rod 31, and the other end is fixed to the outer surface of the side-strike ball 322. The telescopic rod 321 is threadedly connected with a first locking member 3211 for locking its length. In this embodiment, the first locking member 3211 is a locking bolt. In this way, the length of the telescopic rod 321 can be adjusted according to the size of the sand box, so that the main rod 31 can strike the side wall of the sand box of different sizes when performing the predetermined movement, thereby improving the applicability of the side-strike mechanism 3 to sand boxes of different sizes.

[0038] Reference Figure 5-6The side-strike ball 322 has a certain elasticity and has an injection cavity 3221 formed therein. An injection hole 3222 is formed on the outer surface of the side-strike ball 322. The injection hole 3222 is connected to the injection cavity 3221. The injection cavity 3221 is filled with a non-Newtonian fluid 3223. An adhesive surface 3212 is provided at one end of the telescopic rod 321 close to the side-strike ball 322. The adhesive surface 3212 is bonded and fixed to the spherical surface of the side-strike ball 322 and the adhesive surface 3212 closes the injection hole 3222. In this way, the non-Newtonian fluid 3223 can be injected into the injection cavity 3221 of the side-strike ball 322 through the injection hole 3222, which is convenient for the production of the side-strike ball 322; when impacting the side wall of the sand box, the non-Newtonian fluid 3223 can become relatively hard, making the side-strike ball 322 hard inside and soft outside, ensuring a certain impact force to facilitate stable vibration of the side wall of the sand box, while reducing the possibility of impact deformation of the sand box, and also reducing the noise generated during the impact.

[0039] Reference Figure 5 and Figure 7 The driving module 5 includes an upper guide plate 51, a lower guide plate 52 and a first driving mechanism 53 fixed on the fixing frame 211. The upper guide plate 51 and the lower guide plate 52 are provided with guide arc grooves 511 with the same trajectory, and the main rod 31 passes through the guide arc grooves 511 on the upper guide plate 51 and the lower guide plate 52 at the same time. The first driving mechanism 53 is connected to the main rod 31 to drive the main rod 31 to move along the guide arc groove 511.

[0040] Reference Figure 1 , Figure 5 and Figure 7 The first driving mechanism 53 includes a first driving member 531, a transverse displacement seat 532 and a longitudinal displacement block 533. The first driving member 531 is mounted on the fixed frame 211. The transverse displacement seat 532 is slidably arranged on the side wall of the vibration table body 1 along the length direction of the vibration table body 1. The first driving member 531 is arranged along the length direction of the vibration table body 1. The driving end of the first driving member 531 is connected to the transverse displacement seat 532. The longitudinal displacement block 533 is fixed to the bottom end of the main rod 31, and the longitudinal displacement block 533 is slidably connected to the transverse displacement seat 532 along the width direction of the vibration table body 1. In this embodiment, the first driving member 531 is a pneumatic push rod. When the first driving member 531 drives the transverse seat 532 to slide along the length direction of the compaction table body 1, the transverse seat 532 drives the longitudinal block 533 to move, and the movement of the longitudinal block 533 drives the main rod 31 to move, and the main rod 31 is guided by the guide arc groove 511, thereby achieving the purpose of driving the main rod 31 to move along the guide arc groove 511.

[0041] Reference Figure 5 and Figure 7-8In order to improve the stability of the main rod 31 when it moves and to prevent the main rod 31 from being deflected in the vertical direction when it moves, which may cause the main rod 31 to get stuck when it moves in the guide arc groove 511, an upper limit block 54 is provided on the upper side of the upper guide plate 51. The upper limit block 54 is slidably sleeved on the main rod 31. A second locking member 541 for locking it on the main rod 31 is threadedly connected on the upper limit block 54. In this embodiment, the second locking member 541 is a locking bolt. In order to reduce the sliding friction between the upper limit block 54 and the upper guide plate 51, thereby reducing the wear of the two, a ball 542 is installed at the bottom of the upper limit block 54, and the ball 542 abuts against the upper guide plate 51.
