Technical Field

[0001] The utility model relates to the technical field of coating spraying, in particular to a coating spraying device for lost foam casting coating. Background Art

[0002] Lost foam casting is a new casting method in which paraffin or foam models similar in size and shape to the casting are bonded and combined into a model cluster. After brushing refractory coating and drying, it is vibrated and shaped in dry quartz sand, poured under negative pressure, the model is vaporized, and the liquid metal occupies the position of the model, and the casting is formed after solidification and cooling. In the lost foam process, a coating prepared from refractory materials needs to be applied to the mold.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 2, the present utility model provides a technical solution: a lost foam coating spraying device, including a plurality of support legs 1, a placement rack 8, a mounting rack 9 and a partition plate 6. The upper ends of the plurality of support legs 1 are respectively fixedly installed with a U-shaped frame one 2 and a U-shaped frame two 3. Stepping motors 4 are fixedly installed on both sides of the U-shaped frame one 2. A driving pulley 401 is fixedly installed on the output shaft of the stepping motor 4. Connecting rotating shafts 301 are rotatably installed on both sides of the U-shaped frame two 3. The U-shaped frame one 2 and the U-shaped frame two 3 are of the same size and shape. The stepping motor 4 is installed on the outside of the U-shaped frame one 2. The output shaft of the stepping motor 4 penetrates through the U-shaped frame one 2. The driving pulley 401 is arranged inside the U-shaped frame one 2. The connecting rotating shaft 301 is arranged inside the U-shaped frame two 3. A driven pulley 302 is fixedly installed on the connecting rotating shaft 301. A belt 5 is installed between the driving pulley 401 and the driven pulley 302. The driving pulley 401 is in transmission connection with the driven pulley 302 through the belt 5. A plurality of support columns 701 are fixedly installed inside both the U-shaped frame one 2 and the U-shaped frame two 3. The upper ends of the support columns 701 are fixedly installed with a sliding bracket 7. One end of the sliding bracket 7 is fixedly installed with an inclined plate 703. A limiting rib 704 is arranged in the middle of the inclined plate 703. Outer extension columns 801 are arranged at both ends of the placement rack 8. A clamping groove 804 is formed on the lower surface of the placement rack 8. A connecting plate 12 is fixedly installed at the end of the output shaft of the stepping motor 4. The connecting rotating shaft 301 is installed inside the U-shaped frame two 3. A connecting plate 12 is fixedly installed at the end of the connecting rotating shaft 301 far away from the U-shaped frame two 3. The partition plate 6 is rotatably connected to both of the above-mentioned connecting plates 12. A plurality of limiting teeth 601 are equidistantly distributed at the upper end of the partition plate 6. The partition plate 6 is located below the outer extension columns 801. The clamping groove 804 is adapted to the limiting rib 704.

[0029] During use, the two stepping motors 4 are synchronously controlled by a single-chip microcomputer; first, place the placement rack 8 with the parts to be processed on the inclined plate 703. It should be noted that at this time, the limiting rib 704 should be located in the clamping groove 804 of the placement rack 8. The placement rack 8 slides from the inclined plate 703 to the sliding bracket 7. At this time, the output shaft of the stepping motor 4 rotates to drive the driving pulley 401 to rotate. The driving pulley 401 drives the driven pulley 302 to rotate through the belt 5. The driven pulley 302 drives the connecting rotating shaft 301 to rotate. Therefore, at this time, the connecting plates 12 fixedly installed on the output shaft of the stepping motor 4 and the connecting rotating shaft 301 start to rotate synchronously, driving the partition plate 6 to rotate in the vertical direction. When the partition plate 6 rises, it jacks up the placement rack 8, and the movement of the placement rack 8 is realized through the action of the limiting teeth 601 and the outer extension columns 801. At this time, the placement rack 8 located on the inclined plate 703 slides down to the sliding bracket 7 under the action of gravity, realizing a reciprocating cycle; after setting the program of the stepping motor 4, placing the placement rack 8 on the inclined plate 703 is one of the few steps that need to be repeated manually in this process, greatly increasing the automation degree during the spraying process.

[0030] Embodiment 2

[0031] See also Figure 1 , Figures 3 to 5 The utility model provides a technical solution: a lost foam coating paint spraying device, the upper surface of the placement frame 8 is respectively provided with two slots 802 and a mounting slot 803, a steel plate mesh 805 is fixedly installed inside the mounting slot 803, the two slots 802 are respectively provided on both sides of the mounting slot 803, the steel plate mesh 805 divides the mounting slot 803 into two upper and lower parts, the distance between two adjacent limiting teeth 601 is greater than the width of the placement frame 8, a groove 702 is provided in the middle of the sliding bracket 7, a cylinder 10 is fixedly installed on the lower surface of the mounting frame 9, the mounting frame 9 is located just above the groove 702, the cylinder 10 adopts an stm32 single-chip microcomputer to control the cylinder, a cover body 11 is fixedly installed on the telescopic end of the cylinder 10, and two inserts 1101 are fixedly connected to the lower surface of the cover body 11, and the inserts 1101 are adapted to the slots 802.

[0032] When in use, the utility model does not involve innovation in spraying, so the spraying device is omitted, and its structure can adopt the existing structure; in the existing spraying process, the paint will remain on the conveyor belt of the conveyor, causing pollution and inconvenience in cleaning. In order to solve this problem, the parts to be processed are placed on the steel plate mesh 805 of the placement rack 8. When the partition plate 6 moves the placement rack 8 to the bottom of the mounting rack 9, the outrigger 801 slides into the groove 702 of the sliding bracket 7 (in order to ensure that the placement rack 8 can reach the bottom of the mounting rack 9, it is necessary to coordinate the position of the mounting rack 9 and the position of the groove 702). When assembling the device, first determine the stroke of the partition plate 6, then open the groove 702, and finally determine the installation position of the mounting bracket 9. The arc-shaped boundary of the groove 702 is convenient for the sliding of the outrigger 801). At this time, the cylinder 10 is controlled to fall, so that the insert 1101 enters the slot 802 to close the spraying space, avoiding the interference of external airflow on the spraying, and avoiding the pollution of the conveyor belt by the remaining sprayed paint. After use, the placement rack 8 can be rinsed; it should be noted that the time interval for the stepper motor 4 to move the adjacent placement rack 8 to the bottom of the mounting rack 9 should be greater than the sum of the spraying process and the time of the cylinder 10 moving up and down.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
