Description

Technical Field

[0001] The present invention relates to the technical field of shakeout equipment, and particularly to a vibratory shakeout equipment for processing water pump castings. Background Art

[0002] In sand casting, the molding materials mixed in a certain proportion are called molding sand after being mixed and meeting the requirements of core making. Molding sand is usually made by mixing silica sand, binders (commonly clay or tung oil, etc.) and water in a certain proportion. Sometimes, auxiliary materials such as pulverized coal or wood chips (called additives) are added. Currently, the casting industry still mainly uses ordinary green sand casting. The quality of molding sand has a direct and important impact on castings. Practical production statistics show that more than 60% of the casting rejects are due to the quality problems of molding sand and molds. In order to reduce the casting reject rate and improve economic benefits.

[0003] When the shakeout device in the prior art separates the molding sand and the casting, the casting and the molding sand fall freely onto the shakeout screen plate, and the vibration force when falling freely onto the shakeout screen plate is used to separate the casting and the molding sand. Insufficient vibration force will result in poor shakeout effect. Summary of the Invention

[0004] To achieve the above object, the present invention is realized through the following technical solutions: A vibratory shakeout equipment for processing water pump castings, including a platform, a fixed cylinder is fixedly connected to the middle of the top of the platform, and a motor is fixedly connected to the middle of the inside of the platform, and the motor is located below the fixed cylinder;

[0005] A connection component, the connection component is fixedly connected to the output end of the motor, and the end of the connection component away from the motor is fixedly connected to a rotating shaft;

[0006] A diversion component, the diversion component is arranged inside the fixed cylinder;

[0007] A vibration component, the vibration component is fixedly connected to the rotating shaft;

[0008] A limiting component, the limiting component is fixedly installed inside the diversion component, the vibration component is located inside the limiting component, the rotating shaft passes through the limiting component and is connected to the vibration component, and a trapezoidal cylinder is fixedly connected to the side of the limiting component close to the motor;

[0009] Among them, the vibration assembly includes a fixing plate. Circular holes are provided on the outer side of the fixing plate, and the number of circular holes is multiple. The multiple circular holes are evenly distributed on the fixing plate. A fixing block is fixedly connected to the middle of the bottom of the fixing plate. A spring is fixedly connected to the inner cavity of the fixing block. Place the casting on the fixing plate. The motor is externally powered and operates. The motor drives the rotating shaft to rotate through the connecting component. The rotating shaft drives the fixing block to rotate through the clamping block located inside the clamping groove. The fixing block drives the fixing plate to rotate. The ball at the bottom of the fixing plate rotates on the top of the cone. Contact and extrusion occur between the ball and the rib. The ball drives the fixing plate and the fixing block to move away from the rib. The spring is stretched under force. When the ball passes through the rib, under the action of the elastic force of the spring and the gravity of the fixing plate, the fixing plate resets. 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 from the casting. The molding sand detaches from the fixing plate through the circular holes on the fixing plate. By adjusting the rotation speed of the motor, the frequency of the up and down vibration changes, so as to perform knock-out treatment on different castings. At the same time, the casting and the molding sand on the fixing plate are subjected to centrifugal force and are thrown out in the direction away from the casting, thereby accelerating the separation progress of the molding sand and the casting. The fixing block is slidably connected to the rotating shaft. A clamping block is fixedly connected to the side of the fixing block close to the rotating shaft. The fixing block is rotationally connected to the rotating shaft through the clamping block. A clamping groove adapted to the clamping block is provided on the outer side of the rotating shaft. One end of the spring away from the fixing block is fixedly connected to the rotating shaft.

[0010] Preferably, a plurality of round rods are fixedly connected to the bottom edge of the fixing plate. The plurality of round rods are evenly distributed around the rotating shaft. One end of the round rod away from the fixing plate is rotatably connected to a ball.

[0011] Preferably, the limiting component includes a circular plate. The fixing plate is located above the circular plate. The circular plate is fixedly connected to the inner wall of the guiding component. A groove is formed at the outer edge of the circular plate. The number of grooves is multiple, 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 is arranged in a dislocation manner with the groove. A circular ring is fixedly connected to the outer side of the fixing rod. The casting is placed above the fixing plate. The motor is externally powered to work. The motor drives the rotating shaft to rotate. The rotating shaft drives the fixing plate and the casting to rotate. Under the action of centrifugal force, the casting moves towards the edge as the fixing plate rotates, so that the casting collides with the contact block on the side. The contact block is stressed to drive the connecting rod to move away from the casting. Under the connecting action of the connecting rod, the sliding rod moves towards one end away from the fixing rod in the annular groove, and the elastic plate is stressed and stretched. As the fixing plate rotates, the casting continuously collides with the contact block on the side. The impact force generated by the collision helps to break the adhesive force between the casting and the molding sand, making it easier for the molding sand to fall off 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, so that the molding sand is squeezed out of these dead corners, enhancing the overall sand falling effect. The number of circular rings is two. An annular groove is formed on the outer side of the circular ring. The number of annular grooves is multiple. The two annular grooves are divided into a group. The annular grooves of a group are symmetrically arranged with the fixing rod as the center. A sliding rod is slidably connected to the inside of the annular groove. The two circular rings are symmetrically arranged with the sliding rod as the center. The sliding rod passes through the circular ring through the annular groove. A connecting rod is arranged on the side of the circular ring away from the sliding rod. The connecting rod is rotatably connected to the sliding rod. One end of the connecting rod away from the sliding rod is rotatably connected to a contact block. The contact block is made of an elastic material. The two ends of the contact block are respectively rotatably connected to the two connecting rods on both sides of the fixing rod. An elastic plate is fixedly connected to the outer side of the sliding rod. The two ends of the elastic plate are respectively fixedly connected to the two sliding rods on both sides of the fixing rod. A cone is fixedly connected to the middle of the top of the circular plate. The rotating shaft passes through the cone. The molding sand is separated from the casting under the action of the vibration force. Part of the molding sand falls onto the cone through the round hole on the fixing plate, and the other part of the molding sand is thrown out under the action of centrifugal force and falls onto the inner wall of the guiding component. Then the molding sand flows downward through the groove on the circular plate. By arranging a cone at the bottom of the fixing plate, the inclined surface of the cone can provide a guiding effect for the molding sand, so that the molding sand slides down along the surface of the cone, reducing the accumulation of the molding sand at the bottom of the fixing plate, facilitating the rapid discharge of the molding sand, preventing the molding sand from blocking the space below the fixing plate and affecting the sand falling effect and the normal operation of the equipment. The cone is located below the fixing plate. A plurality of convex strips are fixedly connected to the outer side of the cone. The plurality of convex strips are evenly distributed on the outer side of the cone. The ball contacts the outer side of the cone.

[0012] Preferably, the diversion assembly includes a protective cover which is fixedly installed inside the fixed cylinder. The inner wall of the protective cover close to the platform is fixedly connected to the circular plate. The inner wall of the protective cover is fixedly connected with diversion blocks. After the molding sand detaches from the casting, under the action of centrifugal force, it falls into the interior of the protective cover. Subsequently, the molding sand flows downward along the diversion blocks on the inner wall of the protective cover and then is discharged through the grooves. By providing the diversion blocks, the molding sand detached from the casting can be guided to flow in a specific direction, preventing the molding sand from scattering and accumulating randomly inside the protective cover, making the sand falling process more orderly, facilitating improving the sand falling efficiency, enabling the molding sand to be discharged from the protective cover more quickly, being conducive to subsequent cleaning and recycling, and also preventing the molding sand from gathering at the corners or narrow parts of the protective cover, reducing the possibility of molding sand blockage, ensuring the normal operation of the sand falling equipment. There are multiple diversion blocks, and the multiple diversion blocks are evenly distributed on the inner wall of the protective cover. The outer side of the diversion block is provided with a notch, and the extension rod is fixedly connected to the inner wall of the protective cover close to the diversion block.

[0013] Preferably, the connection assembly includes a connection block which is fixedly connected to the rotating shaft. The output end of the motor is fixedly connected with a positioning block. An extension groove is provided on the side of the positioning block close to the connection block, and the extension groove extends to the connection block. The inner wall of the extension groove is provided with a spiral plate, and the two ends of the spiral plate are respectively fixedly connected to the connection block and the positioning block. The intermediate block and the intermediate ring are made of rubber. Since the vibration assembly will generate strong vibrations during the working process, by providing the spiral plate, the intermediate block and the intermediate ring, these vibration energies can be absorbed and buffered, reducing the transmission of vibrations between the motor and the vibration assembly, preventing the components of the motor and the vibration assembly from being subjected to excessive stress due to vibrations, protecting the motor from damage, and thus extending the service life of the equipment. One end of the connection block close to the positioning block is fixedly connected with an extension block, and one end of the positioning block close to the connection block is fixedly connected with a limiting block. The extension block and the limiting block are arranged in a staggered manner. One end of the positioning block close to the connection block is fixedly connected with an intermediate ring, and an intermediate block is fixedly connected to the outer side of the intermediate ring. The intermediate block is located at the interval between the limiting block and the extension block.

[0014] The present invention provides a vibrating sand falling device for processing water pump castings, having the following beneficial effects:

[0015] First, for the vibrating sand falling device for processing water pump castings, by adjusting the rotation speed of the motor, the frequency of the up-and-down vibration changes, thereby performing sand falling treatment on different castings. At the same time, the molding sand on the casting and the fixing plate is subjected to centrifugal force and is thrown out in a direction away from the casting, thereby accelerating the separation progress of the molding sand and the casting.

[0016] II. The vibrating shakeout equipment for processing the water pump casting parts can continuously collide the casting with 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 the surface of the casting, improving the shakeout efficiency and making the shakeout process more thorough. At the same time, the collision with the rubber blocks can generate forces in different directions, squeezing the molding sand out of these dead corners and enhancing the overall shakeout effect.

[0017] III. The vibrating shakeout equipment for processing the water pump casting parts can provide a guiding effect for the molding sand through the inclined surface of the cone, enabling the molding sand to slide down along the surface of the cone, reducing the accumulation of the molding sand at the bottom of the fixed plate, facilitating the rapid discharge of the molding sand, preventing the molding sand from blocking the space below the fixed plate and affecting the shakeout effect and the normal operation of the equipment.

[0018] IV. The vibrating shakeout equipment for processing the water pump casting parts can absorb and buffer the vibration energy through the spiral plate, the intermediate block and the intermediate ring, reducing the transmission of vibration between the motor and the vibration components, avoiding excessive stress on the components of the motor and the vibration components due to vibration, protecting the motor from damage, and thus extending the service life of the equipment.

[0038] Among them, the vibration assembly 7 includes a fixing plate 71. A circular hole 72 is formed on the outer side of the fixing plate 71. The number of the circular holes 72 is multiple, and the multiple circular holes 72 are evenly distributed on the fixing plate 71. A fixing block 73 is fixedly connected to the middle of the bottom of the fixing plate 71. A spring 74 is fixedly connected to the inner cavity of the fixing block 73. Place the casting on the fixing plate 71. The motor 4 is powered on to work. The motor 4 drives the rotating shaft 8 to rotate through the connecting assembly 6. The rotating shaft 8 drives the fixing block 73 to rotate through the clamping block 75 located inside the card slot. The fixing block 73 drives the fixing plate 71 to rotate. The ball 77 at the bottom of the fixing plate 71 rotates on the top of the cone 59. Contact and extrusion occur between the ball 77 and the rib 510. The ball 77 drives the fixing plate 71 and the fixing block 73 to move away from the rib 510. The spring 74 is stretched under force. When the ball 77 passes through the rib 510, under the elastic force of the spring 74 and the gravity of the fixing plate 71, the fixing plate 71 resets. As the rotating shaft 8 rotates, the fixing plate 71 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 from the casting. The molding sand detaches from the fixing plate 71 through the circular holes 72 on the fixing plate 71. By adjusting the rotation speed of the motor 4, the frequency of the up and down vibration changes, so as to perform shakeout treatment on different castings. At the same time, the molding sand on the casting and the fixing plate 71 is subjected to centrifugal force and is thrown out in the direction away from the casting, thereby accelerating the separation progress of the molding sand and the casting. The fixing block 73 is slidably connected to the rotating shaft 8. A clamping block 75 is fixedly connected to the side of the fixing block 73 close to the rotating shaft 8.

The number of the round rods 76 is multiple, and the multiple round rods 76 are evenly distributed around the rotating shaft 8. One end of the round rod 76 away from the fixing plate 71 is rotatably connected to a ball 77.

[0040] The second embodiment, on the basis of the first embodiment, please refer to Figures 7 to 8As shown, the limit component 5 includes a circular plate 51. The fixing plate 71 is located above the circular plate 51. The circular plate 51 is fixedly connected to the inner wall of the diversion component 9. A groove 52 is formed at the outer edge of the circular plate 51. The number of the grooves 52 is multiple, and the multiple grooves 52 are evenly distributed on the circular plate 51. A fixing rod 53 is fixedly connected to the top of the circular plate 51. The fixing rod 53 is arranged in a staggered manner with the groove 52. A ring 54 is fixedly connected to the outer side of the fixing rod 53. Place the casting above the fixing plate 71. The motor 4 is externally powered to work. The motor 4 drives the rotating shaft 8 to rotate when it works. The rotating shaft 8 drives the fixing plate 71 and the casting to rotate. Under the action of centrifugal force, the casting moves towards the edge as the fixing plate 71 rotates, causing the casting to collide with the contact block 58 on the side. The contact block 58 is stressed and drives the connecting rod 57 to move away from the casting. Under the connection action of the connecting rod 57, the sliding rod 56 moves towards one end away from the fixing rod 53 in the annular groove 55, and the elastic plate 511 is stressed and stretched. As the fixing plate 71 rotates, the casting continuously collides with the contact block 58 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 shakeout efficiency and making the shakeout 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 extruded from these dead corners, enhancing the overall shakeout effect. The number of the rings 54 is two. An annular groove 55 is formed on the outer side of the ring 54. The number of the annular grooves 55 is multiple. Two annular grooves 55 are grouped together. The group of annular grooves 55 is symmetrically arranged with the fixing rod 53 as the center. A sliding rod 56 is slidably connected inside the annular groove 55. The two rings 54 are symmetrically arranged with the sliding rod 56 as the center. The sliding rod 56 passes through the ring 54 through the annular groove 55. A connecting rod 57 is arranged on the side of the ring 54 away from the sliding rod 56. The connecting rod 57 is rotatably connected to the sliding rod 56. One end of the connecting rod 57 away from the sliding rod 56 is rotatably connected to a contact block 58. The contact block 58 is made of elastic material. The two ends of the contact block 58 are respectively rotatably connected to the two connecting rods 57 on both sides of the fixing rod 53. An elastic plate 511 is fixedly connected to the outer side of the sliding rod 56. The two ends of the elastic plate 511 are respectively fixedly connected to the two sliding rods 56 on both sides of the fixing rod 53. A cone 59 is fixedly connected to the middle of the top of the circular plate 51. The rotating shaft 8 passes through the cone 59. The molding sand detaches from the casting under the action of the vibration force. Part of the molding sand falls onto the cone 59 through the round hole 72 on the fixing plate 71, and the other part of the molding sand is thrown out under the action of centrifugal force and falls onto the inner wall of the diversion component 9. Subsequently, the molding sand flows downward through the groove 52 on the circular plate 51. By arranging the cone 59 at the bottom of the fixing plate 71, the inclined surface of the cone 59 can provide a guiding effect for the molding sand, enabling the molding sand to slide down along the surface of the cone 59, reducing the accumulation of the molding sand at the bottom of the fixing plate 71, facilitating the rapid discharge of the molding sand, preventing the molding sand from blocking the space below the fixing plate 71 and affecting the shakeout effect and the normal operation of the equipment. The cone 59 is located below the fixing plate 71.

[0041] Third Embodiment. On the basis of the first and second embodiments, please refer to Figures 9 to 12 As shown, the flow guiding assembly 9 includes a protective cover 91. The protective cover 91 is fixedly installed inside the fixed cylinder 2. The inner wall of the protective cover 91 close to the platform 1 is fixedly connected to the circular plate 51. A flow guiding block 92 is fixedly connected to the inner wall of the protective cover 91. After the molding sand detaches from the casting, under the action of centrifugal force, it falls into the inside of the protective cover 91. Subsequently, the molding sand flows downward along the flow guiding block 92 on the inner wall of the protective cover 91, and then is discharged through the groove 52. By providing the flow guiding block 92, the molding sand detached from the casting can be guided to flow in a specific direction, avoiding the random scattering and accumulation of the molding sand in the protective cover 91, making the sand falling process more orderly, facilitating improving the sand falling efficiency, enabling the molding sand to be discharged from the protective cover 91 more quickly, being convenient for subsequent cleaning and recycling, and also preventing the molding sand from gathering in the corners or narrow parts of the protective cover 91, reducing the possibility of molding sand blockage, ensuring the normal operation of the sand falling equipment. The number of the flow guiding blocks 92 is multiple, and the multiple flow guiding blocks 92 are evenly distributed on the inner wall of the protective cover 91. A notch 93 is formed on the outer side of the flow guiding block 92, and an extension rod 94 is fixedly connected to the flow guiding block 92 close to the inner wall of the protective cover 91.

[0042] The connection assembly 6 includes a connection block 61. The connection block 61 is fixedly connected to the rotating shaft 8. The output end of the motor 4 is fixedly connected to a positioning block 62. An extension groove 63 is formed on one side of the positioning block 62 close to the connection block 61, and the extension groove 63 extends to the connection block 61. A spiral plate 64 is provided on the inner wall of the extension groove 63. The two ends of the spiral plate 64 are respectively fixedly connected to the connection block 61 and the positioning block 62. The intermediate block 65 and the intermediate ring 66 are made of rubber. Since the vibration assembly 7 will generate strong vibrations during the working process, by providing the spiral plate 64, the intermediate block 65 and the intermediate ring 66, the vibration energy can be absorbed and buffered, reducing the transmission of vibrations between the motor and the vibration assembly, avoiding excessive stress on the components of the motor 4 and the vibration assembly 7 due to vibrations, protecting the motor 4 from damage, and thus extending the service life of the equipment. One end of the connection block 61 close to the positioning block 62 is fixedly connected to an extension block 68, and one end of the positioning block 62 close to the connection block 61 is fixedly connected to a limiting block 67. The extension block 68 and the limiting block 67 are arranged in a staggered manner. One end of the positioning block 62 close to the connection block 61 is fixedly connected to an intermediate ring 66, and an intermediate block 65 is fixedly connected to the outer side of the intermediate ring 66. The intermediate block 65 is located at the interval between the limiting block 67 and the extension block 68.

[0043] During use, place the casting above the fixed plate 71. Connect the motor 4 to an external power supply to operate. When the motor 4 operates, it drives the rotation of the rotating shaft 8. The rotating shaft 8 drives the fixed block 73 to rotate through the clamping block 75 located inside the card slot. The fixed block 73 drives the fixed plate 71 to rotate. The ball 77 at the bottom of the fixed plate 71 rotates on the top of the conical body 59. Contact and extrusion occur between the ball 77 and the rib 510. The ball 77 drives the fixed plate 71 and the fixed block 73 to move away from the rib 510, and the spring 74 is stretched under force. When the ball 77 passes through the rib 510, under the elastic force of the spring 74 and the gravity of the fixed plate 71, the fixed plate 71 resets. As the rotating shaft 8 rotates, the fixed plate 71 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 from the casting. The molding sand detaches from the fixed plate 71 through the round hole 72 on the fixed plate 71.

[0044] The rotating shaft 8 drives the fixed plate 71 and the casting to rotate. Under the action of centrifugal force, the casting moves towards 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 stressed and drives the connecting rod 57 to move away from the casting. Under the connection of the connecting rod 57, the sliding rod 56 moves towards one end away from the fixed rod 53 in the annular groove 55, and the elastic plate 511 is stretched under force. As the fixed plate 71 rotates, the casting continuously collides 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 and improving the sand removal efficiency.

[0045] Under the action of the vibration force, the molding sand detaches from the casting. Part of the molding sand falls onto the conical body 59 through the round hole 72 on the fixed plate 71, and another part of the molding sand is thrown out under the action of centrifugal force and falls onto the inner wall of the diversion component 9. Subsequently, the molding sand flows downward through the groove 52 on the round plate 51. By arranging the conical body 59 at the bottom of the fixed plate 71, the inclined surface of the conical body 59 can provide a guiding effect for the molding sand, enabling the molding sand to slide down along the surface of the conical body 59, reducing the accumulation of the molding sand at the bottom of the fixed plate 71 and facilitating the rapid discharge of the molding sand.
