Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3A vibrating material densifying device for putting molding sand into a mold comprises a sand box 1. An auxiliary vibrating member is arranged at the lower end of the sand box 1. The auxiliary vibrating member comprises a base 2. A vibrating member is fixedly connected to the inside of the base 2. A fixing table 9 is arranged at the upper end of the base 2. A placement groove 10 is opened in the fixing table 9. A fixing member is arranged in the placement groove 10. The vibrating member is matched with the inner wall of the lower end of the fixing table 9, and the fixing member is matched with the sand box 1.

[0021] Specific working principle and implementation method: Place the sand box 1 on the fixed table 9, and place the sand box 1 on one side of the fixed table 9 according to the size of the sand box 1. Fix the sand box 1 on the fixed table 9 by the fixing member against the sand box 1, and then start the vibrating member arranged in the base 2. The vibrating member and the inner wall of the lower end of the fixed table 9 are movable against each other. As the vibrating member hits the fixed table 9, the fixed table 9 moves rapidly left and right at the upper end of the base 2. The sand box 1 fixed on the fixed table 9 moves rapidly left and right with the fixed table 9. At this time, the molding sand can be quickly filled and compacted by injecting molding sand into the sand box 1. The advantage of such a design is that the sand boxes 1 of different sizes can be fixed on the fixed table 9 by fixing members, and the molding sand can be injected and the vibrating member can be turned on after the sand box 1 is fixed. The lower end of the fixed table 9 is hit by the vibrating member so that the sand box 1 can be quickly moved left and right, so that the molding sand in the sand box 1 can be tightly filled with the mold without manual compaction, so that the molding sand can be gradually filled in the sand box 1 when the molding sand is injected.

A threaded rod 13 is rotatably connected to the middle of the fixing plate 12. The threaded rod 13 passes through the fixing platform 9, and a rotating wheel 14 is fixedly connected to the outer end of the threaded rod 13. Rotating the rotating wheel 14 can drive the threaded rod 13 to rotate, and the threadedly connected threaded rod 13 pushes the fixing plate 12 and the sand box 1 closer. Under the limit of the sliding rods 11 on both sides, the fixing plate 12 can be stably pushed in, and the rotating wheel 14 is continuously rotated to fix the fixing plate 12 against the sand box 1.

The fixed platform 9 moves rapidly left and right with the impact of the vertical plate 6. The convex ring 15 fixed at the lower end of the outer side of the fixed platform 9 can prevent the molding sand from entering between the fixed platform 9 and the base 2, thereby preventing the molding sand from affecting the movement between the fixed platform 9 and the base 2.

[0026] like Figure 3 As shown, both ends of the vertical plate 6 are fixedly connected with gaskets, the gaskets are elastically arranged, and the gaskets are fixed at both ends of the vertical plate 6. The gaskets are in contact with both sides of the inner wall of the fixing platform 9, so that the impact noise can be reduced during the impact.
