Technical Field

[0001] This utility model belongs to the field of spray painting masking tooling technology, specifically a spray painting masking tooling. Background Technology

[0002] In modern industrial production, spray painting is widely used in automobile manufacturing, home appliance production, and machining. Spray painting masking fixtures are important tools for protecting non-painted areas of workpieces, and their performance directly affects the quality of spray painting and production efficiency. However, in the actual spraying process, a large amount of paint will inevitably adhere to the surface of the fixture.

[0003] After the paint cures, it will change the original size and shape of the tooling, resulting in a decrease in masking accuracy, which in turn will produce quality defects such as blurred spraying boundaries and missed spraying, increasing product rework rate and production costs. At present, the main way to remove paint from the tooling surface is manual operation, which is relatively inefficient. In many cases, it is not cleaned in time, which makes subsequent cleaning difficult due to the curing of the paint.

[0004] Therefore, a paint masking fixture is proposed to address the above problems. Utility Model Content

[0032] Specifically, an upper top plate 10 is provided in the groove of the positioning mold 2, and spring telescopic rods 11 are connected to the four corners of the bottom of the upper top plate 10. The spring telescopic rods 11 are provided on the positioning mold 2.

[0033] Furthermore, the spring telescopic rod 11 includes a cylindrical body 111 fixedly connected to the positioning mold 2. A movable plate 112 is provided inside the cylindrical body 111. A spring 113 is connected to the bottom of the movable plate 112. A movable rod 114 is connected to the top of the movable plate 112. The top end of the movable rod 114 passes through the cylindrical body 111 and is fixedly connected to the upper top plate 10. The spring telescopic rod 11 is used to lift the upper top plate 10 so that the workpiece to be painted can be tightly attached to the masking mold cover 5.

[0034] Furthermore, the rotary drive assembly 3 includes a rotating column 31 fixedly connected to the positioning mold 2. The end of the rotating column 31 is fixedly connected to the center position on the right side of the positioning mold 2. The end of the rotating column 31 away from the positioning mold 2 passes through the support frame 1 and is fixedly connected to a driven gear 32. The driven gear 32 is meshed with a driving gear 33. The driving gear 33 is connected to a first motor 34 through a motor shaft. The first motor 34 is mounted on the support frame 1, which allows the workpiece to be painted to rotate to any angle to cooperate with manual painting or equipment painting, making the painting operation more convenient and also convenient to use with the cleaning assembly.

[0035] It is worth noting that the left center position of the positioning mold 2 is connected to the support frame 1 through the support bearing, and a sealing strip 12 is provided on the inner wall of the shielding mold cover 5 near the paint spraying groove 6 to increase the fit between the mold and the workpiece to be painted and prevent paint from adhering to the unpainted area along the gap.

[0036] It is worth noting that the opening and closing drive assembly 7 includes an extension plate 71 disposed on the masking mold cover 5. A first rotating shaft 72 is disposed on the extension plate 71. An electric telescopic rod 73 is connected to the first rotating shaft 72. One end of the electric telescopic rod 73 is connected to a second rotating shaft 74. The second rotating shaft 74 is disposed on the positioning mold 2 and controls the masking mold cover 5 to press on the workpiece that needs to be painted.

[0037] It is worth mentioning that the cleaning component 8 includes a second motor 81 mounted on the support frame 1. The output end of the second motor 81 is connected to a lead screw 82, and the lead screw 82 is threadedly connected to a threaded sleeve 83. The rear side of the threaded sleeve 83 is slidably connected to the rear inner wall of the support frame 1 via a slide rail. The threaded sleeve 83 is fixedly connected to a connecting rod 84, and the connecting rod 84 is fixedly connected to a vertical rod 85. The top of the vertical rod 85 is fixedly connected to a scraper 86. The scraper 86 slides against the masking mold cover 5. By using the structure of the motor driving the lead screw 82, the scraper 86 slides against the masking mold cover 5, which can scrape off the paint adhering to the masking mold cover 5. This allows for timely and rapid cleaning of the paint after painting, reducing the problem of difficult cleaning caused by paint curing.

[0038] The first motor 34, the electric telescopic rod 73, and the second motor 81 are existing technologies and will not be described in detail. In addition, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0039] Working principle and process: Place the workpiece to be painted into the groove on the positioning mold 2, with the side to be painted facing upwards. Activate the electric telescopic rod 73 of the opening and closing drive assembly 7 to extend it, causing the masking mold cover 5 to rotate around the connecting shaft 4 until the masking mold cover 5 presses onto the workpiece. The position of the workpiece to be painted is completely matched with the painting channel 6. The spring 113 of the spring telescopic rod 11 will apply an upward force, causing the upper top plate 10 to move the workpiece upwards, so that the upper surface of the workpiece is tightly against the sealing strip 12. Activate the first motor 34 of the rotation drive assembly 3, which in turn drives the driven gear 32 to rotate. The rotating column 31 drives the positioning mold 2 and the masking mold cover 5 to rotate to a suitable angle to facilitate manual or equipment painting. After painting, the workpiece is quickly removed. Then, the rotating drive assembly 3 makes the masking mold cover 5 vertical. The second motor of the cleaning assembly 8 is started, and the lead screw 82 rotates. The threaded sleeve 83 slides along the slide rail on the inner side of the rear side of the support frame 1. Then, the connecting rod 84 drives the vertical rod 85 and the scraper 86 to move. The scraper 86 can scrape off the paint on the masking mold cover 5, realizing timely and rapid paint cleaning and reducing the problem of difficult cleaning caused by paint curing.
