Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a coating device for the production of lost foam cast iron parts. Background Technology

[0002] In the production of lost foam cast iron parts, coating is a key process. By immersing the lost foam cast iron parts in the coating equipment, the quality and strength of the casting surface are improved.

[0003] A search of Chinese patent CN220716454U reveals a coating device for lost foam casting of iron parts. The device includes a housing and a placement tray. A lifting mechanism is fixedly connected to the upper inner wall of the housing. Lifting columns are fixedly connected to the lower surfaces of the lifting mechanism near their edges. The lifting mechanism is also connected to the upper inner surface of the device, and the lifting columns are connected to the placement tray via ropes. When the lifting mechanism is activated, the placement tray is immersed in a liquid pool. Conventional coating devices often fail to coat iron parts of varying shapes comprehensively, frequently leaving small corners uncoated. However, this device allows the operator to simply place the iron part on the placement rack and activate the lifting mechanism, immersing the iron part in the liquid pool for comprehensive coating. This improves the convenience of the coating device and achieves comprehensive coating of iron parts of different shapes, enhancing the device's adaptability.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. After the coating of the lost foam cast iron parts is completed, during the rising process, excess coating remains on the surface of the placement plate used to place the cast iron parts and the surface of the cast iron parts themselves, which is not convenient to deal with the excess coating. In addition, during the coating process, waste particles on the surface of the cast iron parts will be deposited at the bottom of the coating device, which is not convenient to clean. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device for the production of lost foam cast iron parts.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a coating device for the production of lost foam cast iron parts, including a machine body with an inlet and an outlet fixedly installed on the machine body, a placement plate provided on the inner side of the machine body, a hot air dryer provided on the machine body, and a lifting mechanism provided on the machine body. The lifting mechanism includes two electric telescopic rods symmetrically arranged on the machine body, and a bracket is fixedly installed on the telescopic end of each electric telescopic rod. A support component connected to the placement plate is provided on the bracket.

[0008] Two vibration mechanisms are symmetrically arranged on the inner walls of both sides of the placement plate. Each vibration mechanism includes a fixed shell fixedly installed on the placement plate. Two second springs are connected to the inner wall of the fixed shell. The ends of the two second springs are connected to a locking block adapted to the fixed shell. Two inner wall plates are fixedly installed on the inner walls of both sides of the machine body.

[0009] The machine body is equipped with a cleaning mechanism, which includes two guide components fixedly installed on the machine body. Each guide component is equipped with a long frame, and the bottom end of the long frame is connected to a torsion spring. The two torsion springs are connected together to a bucket that is adapted to the inner wall of the machine body.

[0010] Furthermore, the support assembly includes a mounting bolt movably mounted on the bottom end of the bracket, and a side shell is threaded onto the mounting bolt.

[0011] Furthermore, the support assembly also includes two first springs connected to the inner wall of the side shell, and the ends of the two first springs are connected to a side frame that is fixed to the placement plate.

[0012] Furthermore, the inner wall panel is provided with multiple slots that are adapted to the card block.

[0013] Furthermore, the guiding assembly includes a guide rail fixedly mounted on the body, and a movable block is slidably mounted on the inner side of the guide rail.

[0014] Furthermore, the movable block is threaded with a fastening bolt that is movably connected to the top of the long frame.

[0015] Furthermore, a mesh is fixedly installed on the bucket.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] In this invention, after the paint immersion time is completed, the extension end of the electric telescopic rod is extended by controlling the extension of the extension rod, so that the placement plate moves the cast iron part away from the paint. The placement plate is engaged with the slot of the inner wall plate by the fixed shell and the second spring driving the locking block. During the engagement process, the first spring uses its own elasticity to support the placement plate through the side frame. The extension and contraction of the first spring generates vibration of the placement plate, which facilitates the shaking off of excess paint on the placement plate and the cast iron part, and facilitates subsequent drying work.

[0018] In this invention, the placement plate is periodically removed, and the long frame is moved so that the long frame drives the bucket to move against the inner side of the bottom wall of the machine body via the torsion spring. This allows the bucket to collect the waste particles deposited inside the machine body. By unscrewing the fastening bolt from the inside of the moving block, the bucket loaded with waste particles is moved out of the inner side of the machine body via the moving long frame, thus facilitating the cleaning of the waste particles.

[0027] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] like Figures 1 to 6 As shown, an embodiment of this utility model provides a coating device for the production of lost foam cast iron parts, including a body 1, an inlet 2 and an outlet 3 fixedly installed on the body 1, a placement plate 4 provided on the inner side of the body 1, a hot air dryer 5 fixedly installed on the body 1, and a lifting mechanism provided on the body 1. The lifting mechanism includes two electric telescopic rods 6 symmetrically fixedly installed on the body 1, and a bracket 7 fixedly installed on the telescopic end of each electric telescopic rod 6. A support component connected to the placement plate 4 is provided on the bracket 7.

[0029] In this embodiment of the utility model, inlet 2 is connected to an external conveying device, and outlet 3 is connected to an external processing device. The operator controls the external conveying device to transport the coating to the inside of the machine body 1, places the cast iron part on the placement plate 4, controls the extension end of the electric telescopic rod 6 to retract to the fixed end, so that the extension end of the electric telescopic rod 6 drives the placement plate 4 to move downward, so that the placement plate 4 drives the cast iron part to move into the inside of the coating for coating work. After immersion for a suitable time, the extension end of the electric telescopic rod 6 is controlled to extend, so that the placement plate 4 drives the cast iron part out of the inside of the coating, and the hot air dryer 5 is controlled to operate, so that the hot air dryer 5 delivers hot air to the cast iron part for drying work.

[0030] Figures 1 to 6 As shown, two vibration mechanisms are symmetrically arranged on the inner walls of both sides of the placement plate 4. Each vibration mechanism includes a fixed shell 12 fixedly installed on the placement plate 4. Two second springs 13 are connected to the inner wall of the fixed shell 12. The ends of the two second springs 13 are connected to a locking block 14 that is compatible with the fixed shell 12. Two inner wall plates 15 are fixedly installed on the inner walls of both sides of the machine body 1.

[0031] The support assembly includes a mounting bolt 8 movably mounted on the bottom of the bracket 7, with a side shell 9 threaded onto the mounting bolt 8. The support assembly also includes two first springs 10 connected to the inner wall of the side shell 9. The ends of the two first springs 10 are connected to a side frame 11 fixed to the placement plate 4. The inner wall plate 15 has multiple slots 16 that are adapted to the locking block 14.

[0032] In this embodiment of the utility model, after the paint immersion time is completed, the worker controls the extension end of the electric telescopic rod 6 to extend, so that the placement plate 4 moves the cast iron part away from the paint. The placement plate 4 drives the locking block 14 to engage with the locking groove 16 of the inner wall plate 15 through the fixing shell 12 and the second spring 13. The second spring 13 can support the locking block 14 with its own elasticity. During the engagement process, the first spring 10 supports the placement plate 4 through the side frame 11 with its own elasticity. The extension and contraction of the first spring 10 generates vibration of the placement plate 4, which facilitates the shaking off of excess paint on the placement plate 4 and the cast iron part, and facilitates subsequent drying work.

[0033] Workers can disassemble the placement plate 4 by unscrewing the mounting bolt 8 out of the inside of the side shell 9.

[0034] Figures 1 to 6 As shown, a cleaning mechanism is provided on the machine body 1. The cleaning mechanism includes two guide components fixedly installed on the machine body 1. Each guide component is provided with a long frame 20. The bottom end of the long frame 20 is connected to a torsion spring 21. The two torsion springs 21 are connected together to a bucket 22 that is adapted to the inner wall of the machine body 1. The guide component includes a guide rail 17 fixedly installed on the machine body 1. A moving block 18 is slidably installed on the inner side of the guide rail 17. A fastening bolt 19 that is movably connected to the top end of the long frame 20 is threaded on the moving block 18. A mesh 23 is fixedly installed on the bucket 22.

[0035] In this embodiment of the utility model, the staff periodically removes the placement plate 4 and moves the long frame 20. Under the action of external force, the long frame 20 can drive the moving block 18 to move along the inner side of the guide rail 17 through the fastening bolt 19. This allows the long frame 20 to drive the bucket 22 to move against the inner side of the bottom wall of the machine body 1 through the torsion spring 21, so that the bucket 22 can collect the waste particles deposited on the inner side of the machine body 1. By unscrewing the fastening bolt 19 from the inner side of the moving block 18, the bucket 22 loaded with waste particles is moved out of the inner side of the machine body 1 by moving the long frame 20. When the bucket 22 is separated from the machine body 1, the torsion spring 21 can use its own elasticity to drive the bucket 22 to rotate, so that the opening of the bucket 22 faces upward. When the bucket 22 removes the paint, the paint in the bucket 22 can be removed from the bucket 22 through the mesh 23. The mesh 23 intercepts the waste particles, thereby facilitating the cleaning of the waste particles.

[0036] After cleaning the bucket 22, move the bucket 22 back into the inner side of the machine body 1. The bucket 22 is then brought into contact with the inner side of the bottom wall of the machine body 1 by the support of the torsion spring 21. The long frame 20 is fixed by the fastening bolt 19 and the moving block 18. The long frame 20 is then moved so that the bucket 22 moves to the initial position.

[0037] Working principle: The operator controls the external conveying equipment to transport the paint to the inside of the machine body 1, places the cast iron part on the placement plate 4, and controls the extension end of the electric telescopic rod 6 to retract to the fixed end, so that the extension end of the electric telescopic rod 6 drives the placement plate 4 to move downward, so that the placement plate 4 carries the cast iron part into the inside of the paint for paint coating. After immersion for a suitable time, the extension end of the electric telescopic rod 6 is controlled to extend, so that the placement plate 4 carries the cast iron part out of the inside of the paint. The placement plate 4 is engaged with the slot 16 of the inner wall plate 15 by the fixed shell 12 and the second spring 13. During the engagement process, the first spring 10 uses its own elasticity to support the placement plate 4 through the side frame 11. The extension and retraction of the first spring 10 generates vibration of the placement plate 4, so as to shake off the excess paint on the placement plate 4 and the cast iron part. The operator controls the operation of the hot air dryer 5 to deliver hot air to the cast iron part for drying.

[0038] The staff periodically removes the placement plate 4 and moves the long frame 20, so that the long frame 20 drives the bucket 22 to move against the inner side of the bottom wall of the machine body 1 through the torsion spring 21. This allows the bucket 22 to collect the waste particles deposited inside the machine body 1. By unscrewing the fastening bolt 19 from the inside of the moving block 18, the bucket 22 loaded with waste particles is moved out of the inner side of the machine body 1 by moving the long frame 20. The waste particles in the bucket 22 are then cleaned, and the cleaned bucket 22 is reinstalled on the machine body 1.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
