Description

Technical Field

[0001] This utility model relates to the field of casting auxiliary equipment technology, specifically a casting sand blowing device. Background Technology

[0002] Sand blowing in casting is a crucial step in the casting process for cleaning loose sand and residual sand from sand cores or casting surfaces. Its core function is to precisely remove molding sand using high-pressure airflow or industrial gas, thereby improving casting quality. Functionally, high-pressure airflow can remove oxides and impurities from the casting surface, protect the molten metal, and improve surface finish. It can also control the casting temperature by adjusting the air pressure and blowing time, adapting to sand cores of different specifications. It has a wide range of applications, such as when removing loose sand from sand cores, the rotating nozzle forms an air ring for efficient sand removal; when cleaning the socket of casting pipes, the exhaust pipe can simultaneously blow axially and radially, achieving dust-free operation in conjunction with a sand collection system. However, at present, sand blowing operations in castings still rely heavily on manual labor in some industries, which can easily lead to dead corners or uneven sand blowing. Existing technologies may already have solutions to these problems, but this project aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] The high / low adjustment motor is installed inside the high / low power housing, the high / low adjustment screw is installed inside the device housing and connected to the high / low adjustment motor, the auxiliary slide is installed inside the device housing, a pair of support lugs are respectively fitted on the auxiliary slide and the high / low adjustment screw, the symmetrical semi-convex filter is installed inside the device housing and connected to a pair of negative pressure suction pumps, the device housing has a sand storage chamber connected to the symmetrical semi-convex filter, the pair of negative pressure suction pumps are respectively installed on a pair of suction pump bases, a pair of auxiliary sliding bearings are respectively installed on the support lugs and fitted on the auxiliary slide, and the pair of support lugs are respectively connected to the displacement sand blowing assembly;

[0005] It should be noted that, as described above, the casting to be sand-blown is placed inside the device housing. The electric telescopic push rod is extended to fully fix the casting, driving the height adjustment motor inside the height and low power housing, thereby rotating the height adjustment screw and causing the support lugs to move downward or upward. At the same time, the support lugs on the opposite side slide on the auxiliary sliding column based on a pair of auxiliary sliding bearings, causing the displacement sand-blowing assembly to move up and down repeatedly to perform sand-blowing operations on the casting. Simultaneously, a pair of negative pressure air pumps on a pair of suction pump bases operate, drawing air out of the device housing, so that the sand is filtered by the symmetrical semi-convex filter and blown to the outside. Because the screens on both sides of the symmetrical semi-convex filter are denser than the screen at the bottom, the sand particles fall into the sand storage chamber and are collected uniformly. After sand-blowing is completed, the sand is uniformly cleaned and sorted. The protective pressure-reducing pads set on the symmetrical semi-convex filter can fully protect the casting and prevent the symmetrical semi-convex filter from causing wear on the bottom of the casting.

[0006] Preferably, the displacement sand blowing assembly includes: an electric telescopic push rod, a rotary power motor, a drive gear disk, a cooperating gear ring, a bearing ring plate, a bearing inner ring, a plurality of compressed air pumps, and a plurality of sand blowing air guns;

[0008] It should be noted that, as described above, the drive rotary motor causes the drive gear disk to rotate, and because the drive gear disk meshes with the cooperating gear ring, the drive gear disk will drive the cooperating gear ring to rotate when it rotates, thereby causing the inner bearing ring to rotate and displace within the bearing ring plate. At the same time, multiple compressed air pumps operate, compressing the outside air and transmitting it to multiple sand blowing guns, which are then discharged from the sand blowing guns and blown onto the surface of the casting, thus completing the sand blowing operation.

[0009] Preferably, the high and low power housings are provided with maintenance and inspection ports;

[0010] Preferably, the electric telescopic push rod is provided with an anti-slip rubber pad;

[0011] Preferably, a protective pressure-reducing pad is provided on the symmetrical semi-convex filter screen;

It offers the following advantages compared to existing technologies: This device utilizes a lifting and displacement structure with a blowing ring. This ingenious design allows multiple sand blowing guns to continuously rotate and shift positions. Furthermore, the structure supports flexible adjustment of the longitudinal height.

[0022] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-3 As shown, a casting sand blowing device includes: a device housing 1, a high / low power housing 2, and a pair of suction pump bases 3. The pair of suction pump bases 3 are respectively mounted on the device housing 1. The high / low power housing 2 is mounted on the device housing 1. A blowing ring lifting and displacement structure is installed inside the device housing 1. The blowing ring lifting and displacement structure includes: a high / low adjustment motor 4, a high / low adjustment screw 5, an auxiliary sliding column 6, a pair of supporting lugs 7, a symmetrical semi-convex filter screen 8, a sand storage chamber 9, a pair of negative pressure suction pumps 10, and a pair of auxiliary sliding bearings 12. The high / low adjustment motor 4 is mounted on... Inside the high / low power housing 2, the high / low adjustment screw 5 is installed inside the device housing 1 and is connected to the high / low adjustment motor 4. The auxiliary slide 6 is installed inside the device housing 1. A pair of supporting lugs 7 are respectively fitted onto the auxiliary slide 6 and the high / low adjustment screw 5. The symmetrical semi-convex filter 8 is installed inside the device housing 1 and is connected to a pair of negative pressure air pumps 10. The device housing 1 has a sand storage chamber 9, which is connected to the symmetrical semi-convex filter 8. Connected to each other, a pair of negative pressure air pumps 10 are respectively mounted on a pair of suction pump bases 3, a pair of auxiliary sliding bearings 12 are respectively mounted on the support lugs 7, and the pair of auxiliary sliding bearings 12 are respectively fitted on the auxiliary sliding columns 6, and the pair of support lugs 7 are respectively connected to the displacement sand blowing assembly; the displacement sand blowing assembly includes: an electric telescopic push rod 11, a rotary power motor 13, a drive gear disk 14, a cooperating gear ring 15, a bearing ring plate 16, a bearing inner ring 17, a plurality of compressed air pumps 18, and a plurality of sand blowing air guns 19; the electric telescopic push rod 11 is mounted on Inside the housing 1 of the device, the rotary power motor 13 is mounted on the bearing ring plate 16, the bearing ring plate 16 is connected to a pair of supporting lugs 7, the drive gear disk 14 is connected to the rotary power motor 13, and the drive gear disk 14 meshes with the cooperating gear ring 15, the cooperating gear ring 15 is mounted on the bearing ring plate 16, the bearing inner ring 17 is connected to the cooperating gear ring 15, a plurality of compressed air pumps 18 are respectively mounted on the bearing inner ring 17, and a plurality of sand blowing air guns 19 are respectively mounted on the bearing inner ring 17.

[0023] According to the appendix Figure 1-3The process involves placing the casting to be sandblasted inside the device housing 1, extending the electric telescopic push rod 11 to secure the casting, and driving the height adjustment motor 4 inside the height adjustment housing 2. This causes the height adjustment screw 5 to rotate, which in turn moves the support lug 7 downwards or upwards. Simultaneously, the opposite support lug 7 slides on the auxiliary sliding column 6 using a pair of auxiliary sliding bearings 12. This causes the displacement sandblasting assembly to continuously reciprocate up and down, performing sandblasting on the casting. At the same time, a pair of negative pressure air pumps 10 on a pair of suction pump bases 3 operate, drawing air out of the device housing 1. This allows the sand to be filtered by the symmetrical semi-convex filter screen 8 and blown to the outside. Because the screens on both sides of the symmetrical semi-convex filter screen 8 are denser than the screen at the bottom, the sandblasting process is more efficient. Sand particles fall into the sand storage chamber 9 and are collected uniformly. After sand blowing is completed, the sand is cleaned and sorted uniformly. The protective pressure relief pad set on the symmetrical semi-convex filter screen 8 can fully protect the casting and prevent the symmetrical semi-convex filter screen 8 from causing wear on the bottom of the casting. The drive rotary power motor 13 drives the drive gear disk 14 to rotate. Since the drive gear disk 14 and the cooperating gear ring 15 mesh with each other, the drive gear disk 14 will drive the cooperating gear ring 15 to rotate when it rotates, thereby causing the inner bearing ring 17 to rotate and displace within the bearing ring plate 16. At the same time, multiple compressed air pumps 18 operate, compressing the outside air and transmitting it to multiple sand blowing air guns 19. Finally, the air is discharged from the sand blowing air guns 19 and blown onto the surface of the casting, thus completing the sand blowing operation.
