Description

Technical Field

[0001] The invention relates to the technical field of sand-falling equipment, in particular to a vibration type sand-falling equipment for processing water pump castings. Background Art

[0002] In sand casting, the molding materials matched in a certain proportion are mixed to meet the requirements of core making, which is called molding sand. Molding sand is usually made by mixing raw sand, binder (commonly used clay or tung oil, etc.) and water in a certain proportion. Sometimes auxiliary materials such as coal powder or sawdust (called additives) are added. At present, the foundry industry is still dominated by ordinary wet sand casting. The quality of molding sand has a direct and important impact on castings. Actual production statistics show that more than 60% of casting scrap is due to problems with molding sand and casting quality. In order to reduce the casting scrap rate and improve economic benefits.

[0003] The prior art sand-falling device separates the molding sand and the casting by allowing the casting and the molding sand to fall freely onto the sand-falling screen. The vibration force caused by the free fall onto the sand-falling screen is used to separate the casting and the molding sand. Insufficient vibration force will result in poor sand-falling effect. Summary of the Invention

[0009] Among them, the vibration component includes a fixed plate, the outer side of the fixed plate is provided with a circular hole, the number of the circular holes is multiple, and the multiple circular holes are evenly distributed on the fixed plate, the bottom middle of the fixed plate is fixedly connected with a fixed block, the inner cavity of the fixed block is fixedly connected with a spring, the casting is placed on the fixed plate, the motor is connected to an external power supply to work, the motor drives the rotating shaft to rotate through the connecting component, the rotating shaft drives the fixed block to rotate through the block located inside the slot, the fixed block drives the fixed plate to rotate, the ball at the bottom of the fixed plate rotates at the top of the cone, the ball contacts and squeezes the convex strip, the ball drives the fixed plate and the fixed block to move in the direction away from the convex strip, the spring is stretched, and when the ball passes through the convex strip, under the action of the elastic force of the spring and the gravity of the fixed plate The fixing plate is reset, and as the rotating shaft rotates, the fixing plate vibrates up and down. Under the action of the vibration force, the bonding force between the casting and the molding sand is destroyed, and the molding sand falls off the casting, and the molding sand escapes from the fixing plate through the circular hole on the fixing plate. By adjusting the speed of the motor, the frequency of the up and down vibration is changed, so that sand falling processing can be performed on different castings. At the same time, the molding sand on the casting and the fixing plate is subjected to centrifugal force and thrown away from the casting, thereby accelerating the separation of the molding sand and the casting. The fixing block is slidably connected to the rotating shaft, and a clamping block is fixedly connected to the side of the fixing block close to the rotating shaft. The fixing block is connected to the rotating shaft through the clamping block. A clamping groove adapted to the clamping block is provided on the outside of the rotating shaft, and the end of the spring away from the fixed block is fixedly connected to the rotating shaft.

[0010] Preferably, a round rod is fixedly connected to the bottom edge of the fixed plate, and there are multiple round rods, which are evenly distributed around the rotating shaft, and a ball is rotatably connected to one end of the round rod away from the fixed plate.

[0011] Preferably, the limiting assembly includes a circular plate, a fixed plate located above the circular plate, the circular plate is fixedly connected to the inner wall of the guide assembly, a groove is provided at the outer edge of the circular plate, and there are multiple grooves, and the multiple grooves are evenly distributed on the circular plate, a fixing rod is fixedly connected to the top of the circular plate, the fixing rod and the groove are staggered, and a circular ring is fixedly connected to the outer side of the fixing rod, and the casting is placed above the fixed plate, the motor is connected to an external power supply to work, the motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed plate and the casting to rotate, and the casting moves toward the edge as the fixed plate rotates under the action of centrifugal force, so that the casting collides with the contact block on the side, and the contact block is driven by force to drive the connecting rod away from the casting. The casting moves in the direction of the part. Under the connection of the connecting rod, the sliding rod moves in the ring groove toward the end away from the fixed rod, and the spring plate is stretched by force. As the fixed plate rotates, the casting continues to collide with the contact block on the side. The impact force generated by the collision helps to break the adhesion between the casting and the molding sand, making it easier for the molding sand to fall off from the surface of the casting, improving the efficiency of sand falling, and making the sand falling process more thorough. At the same time, the collision with the rubber block can generate forces in different directions, so that the molding sand is squeezed out of these dead corners, thereby improving the overall sand falling effect. There are two circular rings, and a ring groove is opened on the outside of the circular ring. There are multiple ring grooves, and the two ring grooves are divided into a group, and the ring groove of a group is centered on the fixed rod. The cam is symmetrically arranged, and the inner sliding connection of the ring groove is provided with a sliding rod. The two rings are symmetrically arranged with the sliding rod as the center. The sliding rod passes through the ring groove. A connecting rod is provided on the side of the ring away from the sliding rod. The connecting rod is rotatably connected to the sliding rod, and the end of the connecting rod away from the sliding rod is rotatably connected to the contact block.

A cone is fixedly connected to the middle of the top of the circular plate, and the rotating shaft passes through the cone. The molding sand is separated from the casting under the action of the vibration force, and part of the molding sand falls into the cone through the circular hole on the fixed plate. On the molding sand, another part of the molding sand is thrown out under the action of centrifugal force and falls on the inner wall of the guide component. Then the molding sand flows downward through the grooves on the circular plate. By arranging a cone at the bottom of the fixed plate, the inclined surface of the cone can provide a guide for the molding sand, so that the molding sand slides along the surface of the cone, reducing the accumulation of molding sand at the bottom of the fixed plate, which is conducive to the rapid discharge of molding sand and prevents the molding sand from clogging the space under the fixed plate, affecting the sand falling effect and the normal operation of the equipment. The cone is located below the fixed plate, and the outer side of the cone is fixedly connected with a convex strip. There are multiple convex strips, and the multiple convex strips are evenly distributed on the outer side of the cone, and the ball contacts the outer side of the cone.

After the molding sand leaves the casting, it falls into the inside of the protective cover under the action of centrifugal force, and then the molding sand flows downward along the guide block on the inner wall of the protective cover and is then discharged through the groove. By providing the guide block, the molding sand that falls off the casting can be guided to flow in a specific direction, avoiding the molding sand from being scattered and accumulated irregularly in the protective cover, making the sand falling process more orderly, which is conducive to improving the sand falling efficiency, and enabling the molding sand to be discharged from the protective cover faster, facilitating subsequent cleaning and recycling. It can also prevent the molding sand from gathering in the corners or narrow parts of the protective cover, reducing the possibility of molding sand blockage, and ensuring the normal operation of the sand falling equipment. There are multiple guide blocks, and the multiple guide blocks are evenly distributed on the inner wall of the protective cover. Notches are provided on the outer side of the guide blocks, and the guide blocks are fixedly connected with an extension rod near the inner wall of the protective cover.

[0013] Preferably, the connecting assembly includes a connecting block, which is fixedly connected to the rotating shaft, and the output end of the motor is fixedly connected to a positioning block, and an extension groove is opened on the side of the positioning block near the connecting block, and the extension groove extends to the connecting block, and a spiral plate is provided on the inner wall of the extension groove, and both ends of the spiral plate are fixedly connected to the connecting block and the positioning block respectively, and the middle block and the middle ring are made of rubber material. Since the vibration assembly will generate strong vibration during operation, by arranging the spiral plate, the middle block and the middle ring, the vibration energy can be absorbed and buffered, and the transmission of vibration between the motor and the vibration assembly can be reduced, and the components of the motor and the vibration assembly can be prevented from being subjected to excessive stress due to vibration, and the motor is protected from damage, thereby extending the service life of the equipment. One end of the connecting block near the positioning block is fixedly connected to the extension block, and the end of the positioning block near the connecting block is fixedly connected to the limiting block.

At the same time, the molding sand on the casting and the fixed plate is subjected to centrifugal force and thrown away from the casting, thereby accelerating the separation of the molding sand and the casting.

[0016] 2. The vibrating sand-falling equipment used in the processing of water pump castings uses continuous collisions between the casting and the contact blocks on the side. The impact force generated by the collision helps to break the adhesion between the casting and the molding sand, making it easier for the molding sand to fall off from the surface of the casting, improving the sand-falling efficiency and making the sand-falling process more thorough. At the same time, the collision with the rubber block can generate forces in different directions, squeezing the molding sand out of these dead corners, thereby improving the overall sand-falling effect.

[0044] The rotating shaft 8 drives the fixed plate 71 and the casting to rotate. Under the action of centrifugal force, the casting moves toward the edge as the fixed plate 71 rotates, causing the casting to collide with the contact block 58 on the side. The contact block 58 is driven by the force to move the connecting rod 57 in the direction away from the casting. Under the connection action of the connecting rod 57, the sliding rod 56 moves in the annular groove 55 toward the end away from the fixed rod 53, and the spring plate 511 is stretched by the force. As the fixed plate 71 rotates, the casting continues to collide with the contact block 58 on the side. The impact force generated by the collision helps to break the bonding force between the casting and the molding sand, making it easier for the molding sand to fall off from the surface of the casting, thereby improving the sand falling efficiency.

[0045] The molding sand is separated from the casting under the action of vibration force, and part of the molding sand falls onto the cone 59 through the circular hole 72 on the fixed plate 71, and the other part of the molding sand is thrown out under the action of centrifugal force and falls on the inner wall of the guide component 9. Then the molding sand flows downward through the groove 52 on the circular plate 51. By arranging the cone 59 at the bottom of the fixed plate 71, the inclined surface of the cone 59 can provide a guiding effect for the molding sand, so that the molding sand slides along the surface of the cone 59, reducing the accumulation of molding sand at the bottom of the fixed plate 71, which is conducive to the rapid discharge of molding sand.
