[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] After the molding sand is packed, it needs to be vibrated to ensure its overall strength. A vibration table for loose molding sand in V-process casting, disclosed in CN220120350U, includes four guide columns, each with a longitudinal spring fitted to its outer side. The guide columns are movably connected to circular holes in a support plate, and their tops are disc-shaped and snapped onto the top of the support plate. A cam is attached to the bottom of the support plate, and a support box is positioned above it. Two connecting plates are bolted to both sides of the support box, and the four connecting plates are welded to corresponding transverse moving rods. Transverse springs are fitted to the outer side of each transverse moving rod. The transverse springs and the transverse moving rods are slidably connected to a sliding frame, causing the support box to move laterally back and forth, thus evenly dispersing the loose sand inside and improving the compaction effect. However, this vibration table has a complex structure and relies on cams to achieve the up-and-down vibration of the support box, resulting in poor vibration and unsatisfactory compaction.

[0018] Please refer to Figures 1-5 , Figure 1 A schematic diagram of the overall structure of a buffer vibration table for sand casting is provided for some embodiments of this application; Figure 2 for Figure 1 The front view; Figure 3 for Figure 2 A detailed structural diagram of point A in the middle; Figure 4 A cross-sectional view of a buffer vibration table for sand casting provided for some embodiments of this application; Figure 5 for Figure 4 A schematic diagram of the specific structure at point B.

[0019] See appendix Figure 1-5A buffer vibration table for sand casting includes a support platform 1, cylinders 2, a vibrating box 3, a sand box 4, and a vibrating plate 5. The cylinders 2 are arranged in pairs on both sides of the support platform 1. Each cylinder 2 can move the vibrating box 3 left and right along its output direction. A connecting block 6 is fixed to the output shaft of the cylinder 2, and a mating plate 7 is provided at the end of the connecting block 6. The vibrating box 3 is a hollow cuboid structure with an opening at the top. Ear chambers 8 are provided on both sides of the vibrating box 3, and the mating plate 7 cooperates with the ear chambers 8. A first telescopic spring 9 is provided inside the ear chamber 8, and one side of the first telescopic spring 9 is connected to the vibrating plate 5. The outer wall of the moving box 3 is fixedly connected, and the other side of the first telescopic spring 9 is fixedly connected to the mating plate 7. The first telescopic spring 9 can reduce the impact of the vibration of the moving box 3 on the output shaft of the cylinder 2. The cylinder 2 pulls the first telescopic spring 9 to better realize the movement of the moving box 3 on the vibrating plate 5. The sand box 4 is placed inside the moving box 3. The bottom of the moving box 3 is provided with a protrusion 10. The vibrating plate 5 is fixed above the support platform 1. The vibrating plate 5 is provided with a wave protrusion 11. When the protrusion 10 and the wave protrusion 11 come into contact with each other, they will vibrate, thereby realizing the shaking of the moving box 3.

[0020] The vibrating box 3 has openings 12 on both sides, and the sand box 4 has handles on both sides. The openings 12 are used to cooperate with the handles of the sand box 4, so that the compacted sand box 4 can be easily taken out from the openings 12 later.

[0021] Among them, the mating plate 7 is a rectangular structure. The length of the mating plate 7 is less than the length of the ear chamber 8, and the width of the mating plate 7 is less than the width of the ear chamber 8. The mating plate 7 leaves a certain gap in the ear chamber 8 and has a certain shaking space in the vertical direction, so as to ensure that the shaking box 3 can shake up and down during the movement, thereby improving the compaction effect of the molding sand.

[0022] Specifically, the vibration box 3 is equipped with a second telescopic spring 13 and a lifting plate 14. One side of the second telescopic spring 13 is fixed to the bottom of the vibration box 3, and the other side is fixed to the bottom of the lifting plate 14. The lifting plate 14 can support the sand box 4, so that the sand box 4 is subjected to uniform force and ensures the compaction effect of the sand box 4.

[0023] The sand box 4 is placed above the lifting plate 14. The vibration table also includes an upper cover, which is a hollow cuboid structure with an opening at the bottom. The upper cover is detachably mounted above the vibration box 3. The upper cover is used to fix the sand box 4. The sand box 4 and the vibration box 3 are tightly fitted together, thereby realizing the vibration of the sand box 4.

[0024] Specifically, the bump 10 is a granular protrusion, which is irregularly arranged at the bottom of the shaking box 3. The bump 10 can cooperate with the wave protrusion 11 to realize the vibration of the shaking box 3.

[0025] The cylinder 2 includes two sets, and the shaking box 3 has two ear chambers 8 on one side. Correspondingly, there are two mating plates 7 to cooperate with the ear chambers 8, which can ensure the overall stability of the shaking box 3.

[0026] The vibrating plate 5 and the support platform 1 are fixedly connected by bolts.

[0027] Working principle: The sand box 4 is placed inside the vibrating box 3, and the sand box 4 is fixed with the top cover. The sand box 4 and the vibrating box 3 fit tightly together. The protrusion 10 at the bottom of the vibrating box 3 fits tightly with the vibrating plate 5. The cylinder 2 drives the vibrating box 3 to move back and forth, realizing the rapid shaking of the vibrating box 3, thereby achieving the shaking and compaction of the molding sand in the sand box 4. The protrusion 10 is irregularly arranged at the bottom of the vibrating box 3, which increases the vibration frequency of the vibrating box 3. The cylinder 2 is used to drive the vibrating box 3 to move. The first telescopic spring 9 can prevent the vibrating box 3 from affecting the output shaft of the cylinder 2 when the box moves, thus improving the service life of the cylinder 2. Moreover, the area of ​​the mating plate 7 is smaller than the area of ​​the ear chamber 8, so the vibrating box 3 can bounce up and down during the movement, which improves the compaction effect of the molding sand. After the vibration is complete, the top cover is opened and the sand box 4 can be taken out.

[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art, all of which fall within the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
