[0002] In the production process of die-casting pots, surface spraying is a crucial process. It can not only provide a beautiful appearance for die-casting pots, but also enhance their rust prevention, wear resistance and other properties, and extend their service life. With the progress of technology, semi-automatic spraying devices have gradually emerged and replaced traditional manual spraying. These devices are usually equipped with adjustable spray guns and simple conveying systems, which can improve the spraying efficiency and uniformity to a certain extent.

[0003] When spraying a die-casting pot, the die-casting pot needs to be placed on a clamping device. Three or four groups of clamping blocks arranged on the clamping device are attached to the outer wall of the die-casting pot to fix the die-casting pot. However, due to the different size specifications and diameters of die-casting pots, in some existing technologies, when adjusting the position of the clamping blocks to fit the outer walls of die-casting pots with different diameters, it is necessary to release the fixation of the clamping blocks by turning bolts, and then move the clamping blocks one by one for adjustment. After the adjustment is completed, it is necessary to turn the bolts again to fix the position of the clamping blocks. This operation is relatively cumbersome, time-consuming and laborious, reducing the work efficiency. Therefore, a spraying device for die-casting pot production is proposed to solve the above problems. Content of the Utility Model

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 4 shown, the present invention provides a spraying device for die-casting pot production, including a workbench 1. The outer wall of the top end of the workbench 1 is fixedly connected with a negative pressure box 5. The outer wall of the top end of the negative pressure box 5 is fixedly connected with a discharge pipe 6. The outer wall of the top end of the workbench 1 is fixedly connected with a fixing plate 9. An installation mechanism 7 is arranged on the outer wall of the fixing plate 9. The inner wall of the bottom end of the workbench 1 is fixedly connected with a motor 2. The output shaft of the motor 2 is fixedly connected with a rotating plate 3. A clamping mechanism 4 is arranged on the outer wall of the top end of the rotating plate 3. The clamping mechanism 4 includes a partition board 401. A clamping block 402 is slidably connected to the inner wall of the partition board 401. The outer wall of the bottom end of the clamping block 402 is hinged with a moving block 407 through a connecting rod 403. The outer wall of the bottom end of the partition board 401 is fixedly connected with a fixed rod 404. A card slot 405 is opened on the outer wall of the fixed rod 404. An inserting block 406 is elastically connected to the inner wall of the moving block 407 through a telescopic spring 408. The die-casting pot body 8 is in contact with the outer wall of the top end of the partition board 401.

[0022] Adopting the above solution: The workbench 1 can be placed on the ground, and the die-casting pot body 8 to be sprayed is placed on the partition plate 401. The outer wall of the die-casting pot body 8 is clamped and fixed by three groups of clamping blocks 402, and the fixing operation can be completed. During spraying, the motor 2 can be started, and its output shaft drives the rotating plate 3 to rotate. The rotating plate 3 drives the clamping mechanism 4 to rotate synchronously with the die-casting pot body 8. The feeding pipe on the right side of the negative pressure box 5 is connected to an external device. Through the negative pressure box 5, the paint in the external device can be sucked into the discharge pipe 6 through the feeding pipe and sprayed onto the surface of the die-casting pot body 8 through the spray head 706. And because the die-casting pot body 8 rotates continuously during the spraying process, the spraying can be made more uniform. There are three groups of clamping blocks 402, which are evenly distributed at an equal angle in the inner wall of the partition plate 401. A connecting rod 403 is hinged below each group of clamping blocks 402, and the three connecting rods 403 are hinged on the outer wall of a moving block 407. By moving the moving block 407 up and down, the three connecting rods 403 can be driven to turn over, and the connecting rods 403 drive the clamping blocks 402 to move. Since the clamping blocks 402 are slidably connected to the inner wall of the partition plate 401 and are guided by the inner wall of the partition plate 401, they can move outward or inward simultaneously, so that die-casting pot bodies 8 of different sizes and specifications can be clamped.

[0023] As Figure 2 and Figure 3 shown, the fixing rod 404 is fixedly connected to the outer wall of the top end of the rotating plate 3, and the moving block 407 is slidably connected to the outer wall of the fixing rod 404; one end of the connecting rod 403 is hinged to the outer wall of the bottom end of the clamping block 402, and the other end of the connecting rod 403 is hinged to the outer wall of the moving block 407; one end of the telescopic spring 408 is fixedly connected to the outer wall of the plug 406, and the other end of the telescopic spring 408 is fixedly connected to the inner wall of the moving block 407. The outer wall of the plug 406 is slidably connected to the inner wall of the moving block 407, and the plug 406 is engaged with the card slot 405.

[0024] By adopting the above scheme, when not affected by external forces, the telescopic spring 408 drives the plug block 406 to maintain the state of being engaged with a group of slots 405 due to its own elastic force, and limits the moving block 407, so that the positions of the three groups of clamping blocks 402 can be fixed; there are multiple groups of slots 405, which are vertically distributed on the outer wall of the fixing rod 404. The multiple groups of slots 405 can enable the moving block 407 to be moved to multiple positions for fixing, thereby fixing the three groups of clamping blocks 402 at multiple positions, so as to clamp and fix the die-casting pot body 8 of various sizes; when needed When moving block 407 is to be moved up and down, the plug block 406 can be pulled outward to make it disengage from a group of slots 405, so that the limit of moving block 407 can be released to move it up and down. When it moves to a suitable position and the outer walls of the three groups of clamping blocks 402 are all in contact with the outer wall of the die-casting pot body 8, the plug block 406 can be loosened, and it can be clamped with a group of slots 405 under the elastic force of the telescopic spring 408 to complete the clamping of the die-casting pot body 8. There is no need to turn the bolts multiple times and then adjust the position of the clamping blocks 402 one by one. It is more convenient and quick, and improves work efficiency.

[0025] like Figure 4 As shown, the mounting mechanism 7 includes a connecting block 701, the inner wall of the connecting block 701 is elastically connected to a stopper 703 through a connecting spring 702, the outer wall of the connecting block 701 is clamped with a mounting block 704, the bottom outer wall of the mounting block 704 is fixedly connected to a nozzle 706, and the outer wall of the mounting block 704 is provided with a through groove 705; the connecting block 701 is fixedly connected to the bottom outer wall of the fixing plate 9, one end of the connecting spring 702 is fixedly connected to the outer wall of the stopper 703, and the other end of the connecting spring 702 is fixedly connected to the inner wall of the connecting block 701; the outer wall of the stopper 703 is slidably connected to the inner wall of the connecting block 701, and the stopper 703 is clamped with the through groove 705.

[0026] Adopting the above solution: After the nozzle 706 is installed below the connecting block 701, the discharge pipe 6 is in communication with the mounting block 704 and the nozzle 706. The coating in the external device can be sucked into the discharge pipe 6 through the negative pressure box 5 and sprayed out through the nozzle 706. When the nozzle 706 is blocked after long-term use and needs to be removed for cleaning, the two groups of stoppers 703 can be pressed to disengage them from the through slots 705, thus releasing the limit of the mounting block 704. Then, the mounting block 704 and the nozzle 706 can be removed for cleaning. After cleaning, the opening above the mounting block 704 can be aligned with the position of the connecting block 701. The mounting block 704 is moved upward until it contacts the connecting block 701. The arc surface of the stopper 703 moves into the inner wall of the connecting block 701 under the force of being squeezed by the outer wall of the mounting block 704, and the connecting spring 702 is compressed. When the mounting block 704 moves to a position where the through slot 705 corresponds to the stopper 703, the stopper 703 pops out due to the elastic force of the connecting spring 702 itself, and its top straight surface contacts the top inner wall of the through slot 705, thus fixing the mounting block 704 and completing the installation of the nozzle 706, which is relatively convenient.

[0027] The working principle and usage process of the present utility model:

[0028] Place the die-casting pot body 8 to be sprayed on the partition plate 401. By pulling out the plug 406 outward, the telescopic spring 408 is compressed, and the moving block 407 is moved up and down, driving the three groups of connecting rods 403 hinged thereto to flip, thereby causing the three groups of clamping blocks 402 slidably connected to the inner wall of the partition plate 401 to move outward or inward simultaneously. When the three groups of clamping blocks 402 move to fit the outer wall of the die-casting pot body 8, the plug 406 can be released. The telescopic spring 408 drives the plug 406 to be clamped with a group of card slots 405 on the fixed rod 404 to limit the moving block 407, thereby fixing the position of the clamping block 402. And through the setting of multiple groups of card slots 405, clamping of die-casting pot bodies 8 with different sizes and specifications can be achieved, without the need to rotate the bolts multiple times and move the position of each clamping block 402 one by one to make it fit the outer wall of the die-casting pot body 8, which is convenient and fast and improves work efficiency.

[0029] After the die-casting pot body 8 is clamped, the motor 2 can be started. Its output shaft drives the rotating plate 3 to rotate, and the clamping mechanism 4 on the rotating plate 3 and the clamped die-casting pot body 8 rotate synchronously. The feed pipe on the right side of the negative pressure box 5 is connected to an external device. The negative pressure box 5 generates negative pressure to suck the coating in the external device into the discharge pipe 6 through the feed pipe. The coating reaches the nozzle 706 installed below the connecting block 701 from the discharge pipe 6 and is sprayed onto the surface of the rotating die-casting pot body 8. Since the die-casting pot body 8 rotates continuously during the spraying process, the coating can cover its surface more evenly.

[0030] When the nozzle 706 becomes blocked due to long-term use and needs to be cleaned, the two groups of stoppers 703 can be pressed to disengage them from the through slots 705, releasing the limit on the mounting block 704, and then the nozzle 706 can be removed for cleaning. After cleaning, align the opening above the mounting block 704 with the connecting block 701, move the mounting block 704 upward, and the stoppers 703 will move under extrusion. After the mounting block 704 is in place, the stoppers 703 will pop out under the action of the connecting spring 702 and engage with the through slots 705 to complete the installation of the nozzle 706.
