Description

Technical Field

[0001] The utility model relates to the technical field of sand falling devices, in particular to a sand falling device for a casting sand box. Background Art

[0002] A sand dropper, also known as a sand drop machine, is a common foundry equipment used to remove molding sand from castings. It plays an important role in the foundry industry.

[0003] According to the existing technology, when the sand dropper is working, the cam is driven by the motor to rotate, thereby generating centrifugal force to make the sand dropper slide up and down, and the molding sand on the casting can be fallen off when shaking. However, the power of the motor is constant during the rotation process, which will result in a single working mode and thus cannot meet the needs of castings of various weights. The efficiency of the molding sand falling off of castings of different weights when shaking is different, which will reduce the efficiency of production and processing. Utility Model Content

[0024] One end of the sliding shaft 6 is fixedly connected to the third spring 24, one end of the third spring 24 is fixedly connected to the partition 21, both ends of the partition 21 are fixedly connected to the inner wall of the rotating sleeve 5, one end of the connecting rod 11 is fixedly connected to the second spring 23, the second spring 23 is fixedly connected to the inner wall of the fixed block 22, there are two sliding plates 13, one side of the sliding plate 13 is fitted and slidably connected to the inner wall of the box body 18, both sides of the box body 18 are fixedly connected to the connecting blocks 19, the bottom of the connecting block 19 is fixedly connected to the first spring 20, one end of the first spring 20 is fixedly connected to the top of the base 1, the total number of connecting blocks 19 is ten, and the number of first springs 20 corresponds to the number of connecting blocks 19.

[0025] In the first embodiment, by placing the casting on the mesh plate 17, the weight of the casting will drive the mesh plate 17 to sink. During the sinking process, the mesh plate 17 will drive the sliding plate 13 to move. The sliding plate 13 drives the connecting rod 11 to move through the fixed plate 12. When the connecting rod 11 moves, it can drive the connecting plate 9 on the sliding rod 10 to move. The connecting plate 9 controls the position of the rotating wheel 8 from the protrusion 7. When the protrusion 7 moves, it can push the rotating wheel 8 to rise, and form an up and down reciprocating motion effect in sequence. In this way, the amplitude of vibration can be controlled according to the weight of the casting. The heavier the weight, the smaller the amplitude of vibration, and the less damage to the equipment during vibration. Moreover, the small and tight vibration method can also be used for rapid sand dropping work for heavier castings.

[0028] The working principle and usage process of the present invention are as follows: the casting is placed in the box 18, and the weight of the casting will drive the mesh plate 17 to move. When moving, it can drive the sliding plate 13 to move, and the sliding plate 13 drives the connecting rod 11 on the fixed plate 12 to move. When the connecting rod 11 moves, it can drive the sliding rod 10 to move, and the sliding rod 10 drives the rotating wheel 8 to move through the connecting plate 9, and then drives the rotating wheel 4 to rotate by starting the motor 3. When the rotating wheel 4 rotates, it can drive the rotating sleeve 5 to rotate. When the rotating sleeve 5 rotates, it can drive the protrusion 7 on the sliding shaft 6 to push the rotating wheel 8, and then drive the mesh plate 17 to vibrate. When the mesh plate 17 vibrates, it can drive the box 18 to vibrate, so that the vibration of the box 18 can drive the slider 15 in the track 14 to slide, thereby driving the elastic rope 16 on the slider 15 to swing, and it can hit the casting when swinging.
