Description

Technical Field

[0001] The invention relates to the technical field of casting manufacturing, in particular to a vibration conveying type sand-falling machine. Background Art

[0002] A vibrating sand-falling machine is a sand-falling machine, which is mainly composed of two parts: a frame and a base. The frame of the vibrating part is supported on the base of the machine by two rows of springs. Two vibration motors are installed horizontally and symmetrically on the side of the sand-falling machine frame. The resultant force of the exciting force is perpendicular to the upper plane of the grid, forming a single-body structure, which promotes the separation of the sand box from the molding sand, the separation of the casting from the molding sand, and the crushing of the sand clumps. The Chinese patent application with application number 202023310445.X discloses "A conveying vibrating sand-falling machine, specifically relating to the technical field of vibrating sand-falling machines, including a chassis, an inclined bottom plate, a sand outlet pipe and a vibration motor, and a sand-falling mechanism is provided inside the chassis; the sand-falling mechanism includes a plurality of first rotating rollers, the A baffle is provided on the top of one side of the first rotating roller, and extension plates are fixedly provided on the front and rear sides of the bottom of the baffle, and a first threaded rod is fixedly provided on the bottom of the extension plate, and a first hollow rod is threadedly connected to the outer end of the first threaded rod, and two connecting plates are provided on one side of the baffle, and a rotating shaft is fixedly provided on the side of the two connecting plates close to the chassis. The utility model uses the first threaded rod to drive the baffle to move up and down, so that the baffle can block the mold from moving downward to extend the processing time, and uses the second threaded rod to lift one end of the connecting plate, so that the multiple second rotating rollers can be in an inclined position to facilitate the transportation of the mold.

[0003] This technical solution only solves the problem that the vibration time of the casting in the sand shakeout machine is too short, resulting in the failure of the molding sand on the casting to fall completely. In the vibrating conveyor type sand shakeout machine, the short vibration time will also cause the molding sand to be transported out of the sand shakeout machine before it falls completely when the casting is vibrated. Moreover, while the casting is being transported, a small amount of molding sand separated by the vibration will also move with the casting due to the vibration, resulting in part of the molding sand being transported out of the sand shakeout machine at the same time as the casting is transported out of the sand shakeout machine. Moreover, when the sand shakeout machine is vibrating at high frequency, the separated molding sand with small volume and light weight is easily lifted up, resulting in a large amount of dust in the production environment, which not only pollutes the production environment but also easily affects the health of the staff.

When the movable sand falling plate 301 descends, the top plate 309 and the movable plate 310 are driven to descend by the lifting rod 308. When the movable sand falling plate 301 descends to the same plane as the fixed sand falling plate 205, the first motor 306 is stopped. At this time, the movable plate 310 is connected to the sand falling machine box 1 by the lock buckle. The side curtain 311 allows the casting to be closed during the descent and vibration process without affecting the lifting and lowering of the movable sand falling plate 301 and the top plate 309.

[0047] When the first motor 306 is started, the second motor 407 is started at the same time, and the second motor 407 drives the second threaded rod 406 to rotate. When the second threaded rod 406 rotates, the retention plate 403 is driven to descend through the lifting block 404, so that the retention plate 403 follows the movable sand falling plate 301 and descends at the same time, so that the casting remains on the movable sand falling plate 301, and the casting is prevented from moving to the fixed sand falling plate 205. When the movable sand falling plate 301 descends to the same plane as the fixed sand falling plate 205, the second motor 407 is turned off, and then the vibration is started. The vibration generating device 204 drives the sand-falling machine box 1 to vibrate through the vibration generating device 204. At this time, the casting is blocked and retained by the retention plate 403 on the movable sand-falling plate 301 to fully vibrate and shake out the sand. Then the second motor 407 is started and the second motor 407 is controlled to reverse, driving the retention plate 403 to rise, so that the casting on the movable sand-falling plate 301 can be transported to the fixed sand-falling plate 205 while vibrating, so that the casting continues to be vibrated and transported on the fixed sand-falling plate 205. By retaining and vibrating the casting, the effect of vibrating and shaking out the sand is improved;

[0048] When the shakeout box 1 vibrates, the vibration generated by the shakeout box 1 drives the reciprocating frame 503 to move up and down, and the reciprocating frame 503 drives the cam 502 to rotate with the transmission rod 501 as the axis, and drives the transmission rod 501 to rotate, so that the shakeout box 1 drives the transmission rod 501 to rotate when vibrating, and when the transmission rod 501 rotates, the first gear 504 rotates with the transmission rod 501 at the same time, and the second gear 506 is driven to rotate by the first gear 504, so that the crankshaft 505 rotates with the second gear 506, and when the second gear 506 rotates, the piston 510 is driven to reciprocate in the air cylinder 509 through the reciprocating rod 507, and the two pistons 510 on both sides move in the opposite direction to the two pistons 510 in the middle, when the piston 510 moves in the direction close to the support column 201, the air cylinder 509 is in the exhaust state, and when the piston 510 moves in the direction away from the support column 201, the air cylinder 509 is in the exhaust state;

[0049] When the air cylinders 509 on both sides are in the exhaust state, the sand and dust raised under the protective cover 602 are sucked into the dust filter bag 606 in the dust cylinder 605 through the first dust suction pipe 603, and the sand and dust are isolated by the dust filter bag 606. Then, the air from which the sand and dust are filtered out is sucked back into the air cylinder 509 through the air inlet pipe 607. During this process, the air outlet one-way valve in the first air outlet pipe 703 blocks the first air outlet pipe 703, while the middle air cylinder 509 is in the exhaust state. The air in the air cylinder 509 is discharged into the dust flushing pipe 701 through the second air outlet pipe 704, and the air inlet one-way valve in the air inlet pipe 607 blocks the second dust suction pipe 604.

[0050] When the air cylinders 509 on both sides are in the exhaust state, air is introduced into the dust flushing pipe 701 through the first air outlet pipe 703, and the first dust suction pipe 603 is blocked due to the air inlet check valve in the air inlet pipe 607. The middle air cylinder 509 is in the exhaust state, and dust is sucked through the second dust suction pipe 604, and the second air outlet pipe 704 is blocked due to the air outlet check valve.

[0051] The air cylinders 509 on both sides and the middle air cylinder 509 are used to alternately evacuate and exhaust air, so that dust is kept under the protective cover 602, and air is continuously introduced into the dust flushing pipe 701, and then sprayed to the right end of the fixed sand falling plate 205 through the air jet pipe 702, so that before the casting is transported out of the sand falling machine, the air sprayed from the air jet pipe 702 causes the molding sand that moves with the casting to be sprayed away from the casting, thereby preventing the molding sand from being transported out together with the casting, and further improving the sand falling effect.
