Description

Technical Field

[0001] This invention relates to the field of casting equipment, and more specifically, to a coating sand shell casting separation device and method. Background Technology

[0002] Coated sand is molding sand or core sand whose surface is coated with a solid resin film before molding. There are two coating processes: cold and hot. In the cold method, resin is dissolved in ethanol, and hexamethylenetetramine is added during sand mixing to coat the sand grains. The ethanol evaporates to obtain coated sand. In the hot method, the sand is preheated to a certain temperature, resin is added to melt it, and the mixture is stirred to coat the sand grains with resin. Hexamethylenetetramine aqueous solution and lubricant are added, and the mixture is cooled, crushed, and sieved to obtain coated sand. Coated sand is used for casting steel and iron parts. After the casting is treated with coated sand, the coated sand adheres to the surface of the casting and is located inside the casting cavity. Currently, the coated sand inside the casting cavity is manually poured out, and the coated sand adhering to the casting surface is peeled off. This operation is time-consuming and labor-intensive. In addition, manual peeling of the coated sand may not be thorough, and the cleanliness of the casting cannot be guaranteed. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a coating sand shell casting separation device and method, which aims to improve the situation where, after the casting is treated with coating sand, the coating sand adheres to the surface of the casting and is located inside the casting cavity. Currently, the coating sand inside the casting cavity is manually poured out and the coating sand adhering to the surface of the casting is peeled off. This operation is time-consuming and labor-intensive. In addition, there is a problem that the manual peeling of coating sand is incomplete.

[0004] This invention is implemented as follows:

[0005] In a first aspect, the present invention provides a coating sand shell casting separation device, comprising a feeding assembly and a tilting assembly.

[0006] The feeding assembly includes a support part and a positioning part, with the positioning part disposed on the support part.

[0007] The tilting assembly includes a lateral moving part, a longitudinal moving part, an inclined part, and a clamping part. The lateral moving part is disposed on the supporting part, the longitudinal moving part is disposed on the lateral moving part, the inclined part is disposed on the longitudinal moving part, and the clamping part is disposed on the inclined part. The inclined part and the positioning part are disposed correspondingly.

[0008] In one embodiment of the present invention, the support includes a base plate and a frame, the frame being fixed to the upper surface of the base plate.

[0009] In one embodiment of the present invention, the positioning part includes a frame, a drive roller, a plate conveyor belt, and a first motor. The frame is fixed to the upper surface of the base plate. Two drive rollers are provided, one of which is rotatably mounted on the frame. The plate conveyor belt is mounted on the two drive rollers. The first motor is fixed to the outer wall of the frame. One end of the other drive roller is rotatably mounted on the outer wall of the frame, and the other end of the other drive roller is fixed to the output shaft of the first motor.

[0010] In one embodiment of the present invention, the positioning part further includes a positioning box, which is linearly and equidistantly fixed on the plate conveyor belt.

[0011] In one embodiment of the present invention, the transverse movement part includes a second motor, a first lead screw, a first guide rod, and a U-shaped plate. The second motor is fixed on the outer wall of the frame. One end of the first lead screw is rotatably disposed on the frame, and the other end of the first lead screw is fixed together with the output shaft of the second motor. The first guide rod is fixed on the frame. The U-shaped plate is threaded onto the first lead screw and is also slidably disposed on the first guide rod.

[0012] In one embodiment of the present invention, the longitudinal movement part includes a third motor, a second lead screw, a second guide rod, and a support block. The third motor is fixed on the outer wall of the U-shaped plate. One end of the second lead screw is rotatably disposed on the U-shaped plate, and the other end of the second lead screw is fixed together with the output shaft of the third motor. The support block is threaded onto the second lead screw and is also slidably disposed on the second guide rod.

[0013] In one embodiment of the present invention, the inclined portion includes a first cylinder, a first support plate, a spring, a vibrator, a fourth motor, a second support plate, a photoelectric switch, and a third support plate. The first cylinder is fixed on the upper surface of the support block, and the piston rod end of the first cylinder is fixed on the upper surface of the first support plate. The spring is fixed between the lower surface of the first support plate and the upper surface of the third support plate. The vibrator is fixed on the upper surface of the third support plate. The fourth motor is fixed on the lower surface of the third support plate. The output shaft end of the fourth motor is fixed on the upper surface of the second support plate. The photoelectric switch is fixed on the lower surface of the second support plate.

[0014] In one embodiment of the present invention, the inclined portion further includes a circular slide rail and a circular slider. Two circular slide rails are provided, and the two circular slide rails are respectively fixed to the lower surface of the third support plate and the upper surface of the second support plate. The circular slider is rotatably mounted on the two circular slide rails.

[0015] In one embodiment of the present invention, the clamping part includes a vertical plate, a second cylinder, a fifth motor, and a stop plate. The vertical plate is fixed on the lower surface of the second support plate, the second cylinder is fixed on the outer wall of the vertical plate, the piston rod end of the second cylinder is fixed on the outer wall of the fifth motor, the output shaft end of the fifth motor is fixed on the outer wall of the stop plate, and a plurality of vertical plates are axially equidistantly arranged on the second support plate.

[0016] Secondly, the present invention also provides a method for separating coated sand shells in casting, comprising the aforementioned coated sand shell casting separation apparatus, and the following steps:

[0017] S1. Conveying castings: The worker places the casting into the positioning box, the first motor starts working, the rotation of the output shaft of the first motor drives the transmission roller to rotate, and the rotation of the transmission roller drives the plate conveyor belt to rotate, so as to convey the casting forward.

[0018] S2. Grab the casting. As the casting moves forward, when the photoelectric switch detects the presence of the casting, the photoelectric switch transmits a signal to the control terminal. The control terminal controls the first motor to stop working and controls the first and second cylinders to work. The piston rod of the first cylinder extends and retracts, causing the second support plate to move up and down. The piston rods of two of the four second cylinders extend and retract, causing the abutment plate to move. Under the combined action of the first and second cylinders, the abutment plate clamps and fixes the casting.

[0019] S3. Pour out the coated sand. The rotation of the output shaft of the second motor drives the first lead screw to rotate. The U-shaped plate moves laterally under the combined action of the first lead screw and the first guide rod. The rotation of the output shaft of the third motor drives the second lead screw to rotate. The support block moves longitudinally under the combined action of the second lead screw and the second guide rod. Under the combined action of the second motor and the third motor, the casting is separated from the plate conveyor belt. The fifth motor works to drive the casting to rotate, so that the coated sand in the inner cavity of the casting is poured out. The vibrator works, and the casting shakes under the combined action of the vibrator and the spring.

[0020] The beneficial effects of this invention are:

[0021] 1. The worker places the casting into the positioning box. The first motor drives the plate conveyor belt to rotate, thus conveying the casting forward. When the photoelectric switch detects the presence of the casting, it transmits a signal to the control terminal. The control terminal then stops the first motor. Under the combined action of the first and second cylinders, the abutment clamps and fixes the casting. Under the combined action of the second and third motors, the casting is separated from the plate conveyor belt. The fifth motor drives the casting to rotate, causing the coating sand inside the casting cavity to be poured out. The vibrator operates, and the casting shakes under the combined action of the vibrator and springs, making the coating sand inside the casting cavity more thoroughly poured out. The rotation of the output shaft of the fourth motor adjusts the position of the casting, enabling automatic cleaning of the coating sand on the casting, saving labor and time costs.

[0022] 2. Using a solenoid valve, the number of nozzles opened is adjusted. The piston rod of the third cylinder extends and retracts, causing the nozzles to move laterally. The water pump operates, spraying water from the water tank at high speed onto the casting through the first and second water pipes and the nozzles. Under the combined action of the second and third motors, the first and third cylinders, and the water pump, the coating sand inside the casting is cleaned. The coating sand and water fall into the water tank, where a filter screen filters the coating sand, allowing both the coating sand and water to be reused. Then, the nozzles clean the coating sand on the outer surface of the casting. Next, two of the four second cylinders drive the abutment plates to clamp and fix the casting. The above steps are repeated to clean the coating sand on the outer surface of the casting, ensuring the casting is clean. After the casting is cleaned, the control terminal controls the first motor to operate again, following the above steps to clean the next casting. High-speed water is used to rinse and peel off the casting, making the separation of the coating sand from the casting more thorough and ensuring the cleanliness of the casting.

[0039] Specifically, the present invention also provides a method for separating coated sand shells in casting, including the above-mentioned coated sand shell casting separation device, and the following steps:

[0040] S1. Conveying castings: The worker places the casting into the positioning box 124. The first motor 125 starts working. The rotation of the output shaft of the first motor 125 drives the transmission roller 122 to rotate. The rotation of the transmission roller 122 drives the plate conveyor belt 123 to rotate, thus conveying the casting forward.

[0041] S2. Grabbing the casting: During the forward movement of the casting, when the photoelectric switch 239 detects the presence of the casting, the photoelectric switch 239 transmits a signal to the control terminal. The control terminal controls the first motor 125 to stop working and controls the first cylinder 231 and the second cylinder 242 to work. The piston rod of the first cylinder 231 extends and retracts, causing the second support plate 236 to move up and down. The piston rods of two of the four second cylinders 242 extend and retract, causing the abutment plate 244 to move. Under the combined action of the first cylinder 231 and the second cylinder 242, the abutment plate 244 clamps and fixes the casting.

[0042] S3. Pour out the coated sand. The rotation of the output shaft of the second motor 211 drives the first lead screw 212 to rotate. The U-shaped plate 214 moves laterally under the combined action of the first lead screw 212 and the first guide rod 213. The rotation of the output shaft of the third motor 221 drives the second lead screw 222 to rotate. The support block 224 moves longitudinally under the combined action of the second lead screw 222 and the second guide rod 223. Under the combined action of the second motor 211 and the third motor 221, the casting is separated from the plate conveyor belt 123. The fifth motor 243 works to drive the casting to rotate, so that the coated sand in the inner cavity of the casting is poured out. The vibrator 234 works, and the casting shakes under the combined action of the vibrator 234 and the spring 233, so that the coated sand in the inner cavity of the casting is poured out more thoroughly.

[0043] S4. Separate the coated sand adhering to the casting. The rotation of the output shaft of the fourth motor 235 drives the second support plate 236 to rotate, thereby adjusting the orientation of the casting. Under the combined action of the second motor 211, the third motor 221, the first cylinder 231, and the fourth motor 235, the inner cavity of the casting aligns with the nozzle 323. The number of nozzles 323 opening is adjusted using the solenoid valve 324. The piston rod of the third cylinder 321 extends and retracts, causing the nozzle 323 to move laterally. The second motor 211 and the third motor 221 control the forward, backward, left, and right movement of the casting. The first cylinder 231 controls the up and down movement of the casting. The water pump 311 operates, pumping water from the water tank 331. The water is sprayed at high speed onto the casting through the first water pipe 312, the second water pipe 313, and the nozzle 323. Under the combined action of the second motor 211, the third motor 221, the first cylinder 231, the third cylinder 321, and the water pump 311, the coating sand inside the casting is cleaned. The coating sand and water fall into the water tank 331, and the filter screen 332 filters the coating sand, so that both the coating sand and water can be reused. Then the nozzle 323 cleans the coating sand on the outer surface of the casting. Then the other two of the four second cylinders 242 drive the abutment plate 244 to clamp and fix the casting. The above steps are repeated to clean the coating sand on the outer surface of the casting, ensuring that the casting is cleaned thoroughly.

[0044] S5. Process the next casting. After the casting is cleaned, the second motor 211, the third motor 221, the first cylinder 231, the fourth motor 235, the second cylinder 242 and the fifth motor 243 work to move the casting into the positioning box 124. The control terminal controls the first motor 125 to work again. Following the above steps, the next casting is cleaned.

[0045] In summary, the coating sand shell casting separation method is as follows: During use, the worker places the casting into the positioning box 124, the first motor 125 operates, and the rotation of the output shaft of the first motor 125 drives the transmission roller 122 to rotate. The rotation of the transmission roller 122 drives the plate conveyor belt 123 to rotate, thereby conveying the casting forward. During the forward movement of the casting, when the photoelectric switch 239 detects the presence of the casting, the photoelectric switch 239 transmits a signal to the control terminal. The control terminal controls the first motor 125 to stop working, and the first cylinder 231 and the second cylinder 242 operate. The piston rod of the first cylinder 231 extends and retracts, causing the second support plate 236 to move up and down. The piston rods of two of the four second cylinders 242 extend and retract, causing the abutment plate 244 to move.

[0046] Under the combined action of the first cylinder 231 and the second cylinder 242, the abutment 244 clamps and fixes the casting. The rotation of the output shaft of the second motor 211 drives the first lead screw 212 to rotate. The U-shaped plate 214 moves laterally under the combined action of the first lead screw 212 and the first guide rod 213. The rotation of the output shaft of the third motor 221 drives the second lead screw 222 to rotate. The support block 224 moves longitudinally under the combined action of the second lead screw 222 and the second guide rod 223. Under the combined action of the second motor 211 and the third motor 221, the casting is misaligned with the plate conveyor belt 123. The motor 243 drives the casting to rotate, causing the coated sand inside the casting cavity to be poured out. The vibrator 234 operates, and the casting vibrates under the combined action of the vibrator 234 and the spring 233, making the coated sand inside the casting cavity more thoroughly poured out. The rotation of the output shaft of the fourth motor 235 drives the second support plate 236 to rotate, realizing the adjustment of the casting's orientation. Under the combined action of the second motor 211, the third motor 221, the first cylinder 231 and the fourth motor 235, the inner cavity of the casting is aligned with the nozzle 323. The number of nozzles 323 opened is adjusted by using the solenoid valve 324.

[0047] The piston rod of the third cylinder 321 extends and retracts, driving the nozzle 323 to move laterally. The second motor 211 and the third motor 221 control the casting to move forward, backward, left, and right. The first cylinder 231 controls the casting to move up and down. The water pump 311 operates, spraying water from the water tank 331 at high speed onto the casting through the first water pipe 312, the second water pipe 313, and the nozzle 323. Under the combined action of the second motor 211, the third motor 221, the first cylinder 231, the third cylinder 321, and the water pump 311, the coating sand inside the casting is cleaned. The coating sand and water fall into the water tank 331, where the filter screen 332 filters the coating sand, allowing both the coating sand and water to be reused. Then, the nozzle 323 cleans the coating sand on the outer surface of the casting. After that, the four second... The other two cylinders in cylinder 242 drive the abutment plate 244 to clamp and fix the casting. Then, the above steps are performed to clean the coating sand on the outer surface of the casting to ensure the cleanliness of the casting. After the casting is cleaned, the second motor 211, the third motor 221, the first cylinder 231, the fourth motor 235, the second cylinder 242, and the fifth motor 243 work to move the casting into the positioning box 124. The control terminal controls the first motor 125 to work again. Following the above steps, the next casting is cleaned. This coating sand shell casting separation method can automatically clean the coating sand on the casting, saving labor and time costs. In addition, the casting is rinsed and peeled off by high-speed water, so that the coating sand is separated from the casting more thoroughly, which can ensure the cleanliness of the casting.

10. A method for separating coated sand shells in casting, characterized in that, include The coated sand shell casting separation device according to claim 9, and the following steps: S1. Conveying castings: The workers place the castings into the positioning box (124), the first motor (125) starts working, the rotation of the output shaft of the first motor (125) drives the transmission roller (122) to rotate, the rotation of the transmission roller (122) drives the plate conveyor belt (123) to rotate, thus conveying the castings forward. S2. Grab the casting. When the photoelectric switch (239) detects the presence of the casting during the forward movement of the casting, the photoelectric switch (239) transmits the signal to the control terminal. The control terminal controls the first motor (125) to stop working and controls the first cylinder (231) and the second cylinder (242) to work. The piston rod of the first cylinder (231) extends and retracts, causing the second support plate (236) to move up and down. The piston rods of two of the four second cylinders (242) extend and retract, causing the abutment plate (244) to move. Under the combined action of the first cylinder (231) and the second cylinder (242), the abutment plate (244) clamps and fixes the casting. S3. Pour out the coated sand. The rotation of the output shaft of the second motor (211) drives the first lead screw (212) to rotate. The U-shaped plate (214) moves laterally under the combined action of the first lead screw (212) and the first guide rod (213). The rotation of the output shaft of the third motor (221) drives the second lead screw (222) to rotate. The support block (224) moves longitudinally under the combined action of the second lead screw (222) and the second guide rod (223). Under the combined action of the second motor (211) and the third motor (221), the casting is separated from the plate conveyor belt (123). The fifth motor (243) works to drive the casting to rotate, so that the coated sand in the inner cavity of the casting is poured out. The vibrator (234) works, and the casting shakes under the combined action of the vibrator (234) and the spring (233). S4. Separate the coated sand adhering to the casting. The rotation of the output shaft of the fourth motor (235) drives the second support plate (236) to rotate, thereby adjusting the orientation of the casting. Under the combined action of the second motor (211), the third motor (221), the first cylinder (231), and the fourth motor (235), the inner cavity of the casting is aligned with the nozzle (323). The number of nozzles (323) opened is adjusted using the solenoid valve (324). The piston rod of the third cylinder (321) extends and retracts, driving the nozzle (323) to move laterally. The second motor (211) and the third motor (221) control the casting to move forward, backward, left, and right. The first cylinder (231) controls the casting to move up and down. The water pump (311) works, pumping water from the water tank (331). Water is sprayed at high speed onto the casting through the first water pipe (312), the second water pipe (313), and the nozzle (323). Under the combined action of the second motor (211), the third motor (221), the first cylinder (231), the third cylinder (321), and the water pump (311), the coating sand inside the casting is cleaned. The coating sand and water fall into the water tank (331). The filter screen (332) filters the coating sand, so that both the coating sand and water can be reused. Then the nozzle (323) cleans the coating sand on the outer surface of the casting. Then the other two of the four second cylinders (242) drive the abutment plate (244) to clamp and fix the casting. Then the above steps are repeated to clean the coating sand on the outer surface of the casting, ensuring that the casting is cleaned thoroughly. S5. Process the next casting. After the casting is cleaned, the second motor (211), the third motor (221), the first cylinder (231), the fourth motor (235), the second cylinder (242), and the fifth motor (243) work to move the casting into the positioning box (124). The control terminal controls the first motor (125) to work again. Following the above steps, the next casting is cleaned.
