It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] Example
[0021] Please refer to Figure 1-Figure 3 The casting sand shaking device comprises an inclined sand shaking plate 1 and a base 2 arranged on the top of the inclined sand shaking plate 1, a plurality of leakage holes 10 are opened on the inclined sand shaking plate 1, a first vibration component is arranged between the inclined sand shaking plate 1 and the base 2, and the inclined sand shaking plate 1 can be driven to vibrate in the vertical direction of the base 2 through the first vibration component, a fixed baffle 5 is fixedly connected to one side of the top of the inclined sand shaking plate 1, a plurality of curved vibration plates 6 are arranged on the inner side of the fixed baffle 5, a movable baffle 31 is arranged on the other side of the top of the inclined sand shaking plate 1, straight vibration plates 7 are arranged between the curved vibration plates 6 separated from each other, one end of the straight vibration plate 7 is fixedly connected to the inner side of the movable baffle 31, and a second vibration component for driving the movable baffle 31 to vibrate in the length direction of the inclined sand shaking plate 1 is arranged on the inclined sand shaking plate 1.
[0022] Specifically, when in use, the casting is first introduced into the inclined sand vibration plate 1 through the top oblique upper part of the inclined sand vibration plate 1, and the inclined sand vibration plate 1 is driven by the first vibration component to vibrate up and down repeatedly. The casting will gradually slide from the upper oblique part to the lower oblique part of the inclined sand vibration plate 1 until it is separated from the inclined sand vibration plate 1. In this process, the sand on the casting will be separated and fall from the leakage hole 10 to the bottom of the inclined sand vibration plate 1. At the same time, the second vibration component is started, and the second vibration component drives the straight vibration plate 7 to vibrate repeatedly from the upper oblique part to the lower oblique part of the inclined sand vibration plate 1 (that is, the length direction of the inclined sand vibration plate 1), so that the fallen sand can be bounced between the curved vibration plate 6 and the straight vibration plate 7 for a period of time, so that most of the sand can fall through the leakage hole 10 between the curved vibration plate 6 and the straight vibration plate 7, and the other sand continues to be bounced between the next curved vibration plate 6 and the straight vibration plate 7 and falls from the leakage hole 10 at the same time, so that most of the sand can fall from the leakage hole 10, avoiding the blockage of the leakage hole 10.
[0023] In an optional embodiment, the angle between the inclined sand tremor plate 1 and the base 2 is 30-60 degrees, and the inclined setting therebetween facilitates the casting to slide off the bottom end of the inclined sand tremor plate 1 when the sand tremor is completed.
[0024] In an optional embodiment: one end of the curved vibration plate 6 away from the movable baffle plate 31 is rotatably connected to the fixed baffle plate 5 via a rotating block, and the other end of the curved vibration plate 6 is fixedly connected to a second spring 12 on the side obliquely above the inclined sand vibration plate 1, and the end of the second spring 12 away from the curved vibration plate 6 is fixedly connected to a fixed block 11, and the bottom end of the fixed block 11 is fixedly connected to the top of the inclined sand vibration plate 1. Through the cooperation of the second spring 12 and the fixed block 11, the curved vibration plate 6 can also have a certain elasticity, thereby increasing the amplitude of the elastic vibration of the sand material between the curved vibration plate 6 and the straight vibration plate 7, allowing the sand material to fall from the leak hole 10 more effectively.
[0025] In an optional embodiment: the curved vibration plate 6 is arranged in a wave shape, and the straight vibration plate 7 and the movable baffle 31 are arranged at an inclination, and the inclination angle is between 30 degrees and 60 degrees. The shape setting of the curved vibration plate 6 can allow the sand to be better retained and vibrated between the curved vibration plate 6 and the straight vibration plate 7, and the inclination setting of the straight vibration plate 7 can facilitate the sand to be introduced into between the next curved vibration plate 6 and the straight vibration plate 7.
[0026] In an optional embodiment: a guide plate 61 is fixedly connected to one end of the curved vibration plate 6 located at the most oblique lower part of the inclined sand vibration plate 1 near the movable baffle 31. The guide plate 61 is arranged in an arc shape, and the sand material that falls out last is guided out through the guide plate 61 for easy access.

[0028] In an optional embodiment: the second vibration component includes a driving box 3 fixedly connected to the top of the inclined sand shock plate 1, close to the movable baffle 31, a driving motor 32 is fixedly installed inside the driving box 3, and a cam 33 is fixedly connected to the output end of the driving motor 32, a movable plate 35 is slidably connected to the side of the movable baffle 31 inside the cam 33, and a protrusion 36 matching the cam 33 is fixedly connected to the side of the movable plate 35 close to the driving motor 32, and a plurality of third springs 34 are fixedly connected between the other side of the movable plate and the inner wall of the driving box 3, and one end of the movable baffle 31 is movably penetrated into the interior of the driving box 3 and is fixedly connected to the middle part of the side of the movable plate 35 close to the third spring 34. When the driving motor 32 is started, when the tip of the cam 33 is close to the protrusion 36, it will squeeze the movable plate 35 to make the movable plate 35 approach one direction, and when the tip of the cam 33 is away from the protrusion 36, the third spring 34 will push the movable plate 35 to vibrate in the opposite direction, so that the movable plate 35 can vibrate repeatedly.
[0029] In an optional embodiment: a side of the top of the inclined sand vibration plate 1 away from the fixed baffle 5 is fixedly connected with a limit rod 41 arranged parallel to the movable baffle 31, and a side of the movable baffle 31 close to the limit rod 41 is fixedly connected with a limit block 4, and the limit block 4 is slidably sleeved on the surface of the limit rod 41.
