DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Reference Figure 1-Figure 5The utility model discloses a vibrating sand-falling machine and an automatic casting line, comprising a stable base 1, wherein two rectangular frames 2 are arranged on the upper end of the stable base 1, vibration springs 3 are arranged at the four corners of the top of the stable base 1, a vibration frame 4 is arranged on the top of the vibration spring 3, a vibration motor is arranged on the bottom end of the vibration frame 4, a plurality of linearly uniformly distributed first screen bars 5 are fixedly arranged inside the vibration frame 4, a second screen bar 6 is arranged on the low side between two adjacent first screen bars 5, a plurality of transverse sliding bars 7 are connected to the bottom end of each of the second screen bars 6, both ends of the transverse sliding bars 7 pass through the frame wall of the vibration frame 4, and a positioning frame 8 is arranged on both ends of the plurality of transverse sliding bars 7.

[0026] In this embodiment, when in use, the demoulded casting is placed inside the vibration frame 4, and the casting is placed away from the opening of the vibration frame 4, and the opening of the vibration frame 4 is located on the side wall, such as Figure 1 and Figure 3 ;

[0027] After the casting is placed, the vibration frame 4 is vibrated by the setting of the vibration motor, and because the vibration motor is located at the bottom side of the vibration frame 4 close to the opening of the vibration frame 4, the gravity of the vibration motor will make the opening of the vibration frame 4 slightly tilted downward, so that during the vibration of the vibration frame 4, the casting can gradually move closer to the opening under the action of inertia;

[0028] During the vibration of the vibration frame 4, the sand blocks on the surface and inside of the casting will be separated from the casting, and the sand blocks will fall on the upper ends of the first sieve bar 5 and the second sieve bar 6. When the volume of the sand blocks is smaller than the maximum gap between the first sieve bar 5 and the second sieve bar 6, they will fall into the interior of the vibration frame 4 and be discharged, while the sand blocks with a volume larger than the maximum gap of the first sieve bar 5 will stay on the upper ends of the first sieve bar 5 and the second sieve bar 6. Since a transverse sliding bar 7 is provided at the bottom end of the second sieve bar 6, and the two ends of the transverse sliding bar 7 are connected to the rectangular frame 2 through a positioning frame 8, when the vibration frame 4 vibrates and shakes, the second sieve bar 6 will not vibrate with the vibration frame 4, and then the sand blocks staying on the upper ends of the first sieve bar 5 and the second sieve bar 6 will be gradually crushed by the first sieve bar 5 and the second sieve bar 6 when the movement states of the first sieve bar 5 and the second sieve bar 6 are different, thereby effectively preventing the problem of sand blocks being discharged with the casting.

[0029] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the positioning frame 8 includes a connecting rod 81, which is fixedly connected to one side of the transverse sliding rod 7, and both ends of the connecting rod 81 are sleeved with a spring sleeve 82, and one end of the spring sleeve 82 is provided with a sliding groove 83 that slides with the rectangular frame 2.

[0030] In this embodiment, the two ends of the connecting rod 81 are clamped inside the rectangular frame 2 through the setting of the spring sleeve 82, and since the spring sleeve 82 is slidably connected to the side wall of the rectangular frame 2 through the sliding groove 83, and the spring sleeve 82 is a component that provides support in the form of buffering by deformation of the spring or compression of the gas, the connecting rod 81 and the transverse sliding rod 7 can move up and down and forward and backward with the vibration of the vibration frame 4. When the vibration frame 4 vibrates left and right, the first sieve rod 5 and the second sieve rod 6 will move relative to each other, and the sand blocks falling on the upper ends of the first sieve rod 5 and the second sieve rod 6 can be easily crushed by the first sieve rod 5 and the second sieve rod 6, thereby preventing large pieces of sand from being unable to pass through the first sieve rod 5 and the second sieve rod 6.

[0031] In a further preferred embodiment of the present invention, Figure 1-5 As shown, an inclined plate 9 is provided at the inner bottom end of the vibration frame 4 , and one end of the inclined plate 9 passes through the vibration frame 4 .

[0032] In this embodiment, when the sand blocks pass through the gap between the first screen bar 5 and the second screen bar 6, they will fall into the interior of the inclined disk 9, and the inclination angle of the inclined disk 9 is greater than the inclination angle of the vibration frame 4. Therefore, the casting sand falling into the interior of the inclined disk 9 will move to one side under the action of gravity, thereby achieving the purpose of facilitating the collection of the casting sand.

[0033] In a further preferred embodiment of the present invention, Figure 1-5 As shown, elastic rings 10 are provided at the top ends of both sides of the vibration frame 4 , and one side of the elastic ring 10 is connected to the side wall of the rectangular frame 2 .

[0034] In this embodiment, the elastic ring 10 is provided to improve the stability of the connection between the vibration frame 4 and the rectangular frame 2, thereby preventing the vibration frame 4 from colliding with the rectangular frame 2.

[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, when the elastic ring 10 is fully compressed, there is a gap between the second sieve bar 6 and the first sieve bar 5 .

[0036] In this embodiment, by setting the elastic ring 10, the amplitude of the vibration frame 4 is limited during the vibration of the vibration frame 4, so that a gap is always maintained between the first sieve bar 5 and the second sieve bar 6 to prevent the first sieve bar 5 and the second sieve bar 6 from colliding with each other and causing damage to the mold or the device.

[0037] Embodiment 2:

[0038] The utility model discloses an automatic casting line, comprising a mold preparation area, a sand core preparation area, a smelting spraying area, a pouring area, a cooling area and a cleaning area which are connected in sequence. The cleaning area comprises a demoulding machine and a vibrating sand-falling machine, and the vibrating sand-falling machine comprises the vibrating sand-falling machine.

[0039] In this embodiment, the vibrating sand-falling machine is arranged at the discharge port of the demoulding machine, and the demoulded mold is placed inside the vibration frame 4 through a conveyor belt.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
