[0002] As is well known, in the painting of car door handles, certain areas of the handle need to be masked to prevent them from being painted, thus achieving a layered effect of different colors. Traditional masking methods, such as using tape or manual masking tools, are cumbersome, difficult to apply precisely, and can easily damage the surface of the door handle. Furthermore, they cannot effectively cover recessed areas, leading to inconsistent painting quality. Utility Model Content

[0027] Reference Figure 1A paint masking device includes: a housing 100, a receiving groove 500, and a sealing platform 300. The receiving groove 500 is disposed within the housing 100 and can cover a workpiece. The housing 100 can only cover the workpiece within the receiving groove 500. The sealing platform 300 is disposed at the edge of the receiving groove 500 and protrudes outward relative to the bottom of the receiving groove 500. The sealing platform 300 can extend into a groove 900 of the workpiece to seal and mask it. The housing 100 can precisely mask specific parts of a car door handle through the receiving groove 500, thereby achieving a multi-layer, multi-color painting effect. By providing the sealing platform 300 that can extend into the groove 900 of the door handle, the masking device can closely fit the complex shape of the door handle, thereby effectively preventing paint leakage and ensuring a clear color boundary between the uncovered and masked parts, meeting the high requirements for painting effects in automobile manufacturing and repair. Compared to traditional masking tape or manual masking tools, this masker allows for quick start-up of the spraying process simply by installing it in place. This effectively reduces preparation time for masking and spraying, significantly improving spraying efficiency and lowering labor costs. Furthermore, this masker is reusable, thus offering additional cost savings.

[0028] In some embodiments, reference is made to Figure 2 The sealing platform 300 is located at the edge of the housing 100, and both the sealing platform 300 and the receiving groove 500 are located on the back of the housing 100. The sealing platform 300 located at the edge of the housing 100 can effectively block the paint spraying, thereby preventing the paint spraying from entering the receiving groove 500, and thus ensuring that the workpieces inside and outside the receiving groove 500 can form different colors and different layers of paint spraying effect.

[0029] Specifically, the sealing platform 300 is located on the bottom side edge of the back of the housing 100. Of course, the position of the sealing platform 300 can be adjusted according to the requirements of the spraying effect. The specific implementation method is not unique, but can be adjusted accordingly according to the actual situation, and no limitation is made here.

[0030] In some embodiments, reference is made to Figure 4 An inclined surface 700 is provided on the outer side of the housing 100, extending from the front of the housing 100 to the sealing platform 300; the inclined surface 700 is inclined away from the receiving groove 500 in a direction close to the sealing platform 300. The inclined effect of the inclined surface 700 can effectively prevent the housing 100 from obstructing the painting operation on its exterior, thus effectively ensuring that the uncovered part and the covered part form a clear color boundary, so as to meet the high requirements for painting effect in automobile manufacturing and repair.

[0031] In some embodiments, reference is made to Figure 3A shielding wall 600 is provided on the side of the housing 100 away from the sealing platform 300, extending towards the bottom of the receiving groove 500. The shielding wall 600 can effectively shield the workpiece in the receiving groove 500 from the side away from the sealing platform 300, thus effectively preventing paint from entering the receiving groove 500 from the other side, thereby ensuring a clear color boundary between the uncovered and covered parts, meeting the high requirements for painting effect in automobile manufacturing and repair.

[0032] In some embodiments, reference is made to Figure 2 The housing 100 has enclosure walls 150 at both ends, and the enclosure walls 150, shielding walls 600, and sealing platforms 300 cooperate to surround the sides of the receiving groove 500. With the cooperation of the enclosure walls 150, shielding walls 600, and sealing platforms 300, the workpiece in the receiving groove 500 will be fully shielded, thus effectively preventing paint from seeping into the receiving groove 500.

[0033] In some embodiments, reference is made to Figure 4 A transition step 550 is provided between the sealing platform 300 and the bottom of the receiving groove 500. The transition step 550 can lift the workpiece and create a gap between the workpiece and the bottom of the receiving groove 500. After the transition step 550 lifts the workpiece, the workpiece will be relatively far away from the bottom wall of the receiving groove 500, thus effectively avoiding the bottom wall of the receiving groove 500 from scratching the workpiece, thereby effectively improving the appearance integrity of the workpiece.

[0034] It is conceivable that the surface of the transition step 550 can be coated with materials such as wear-resistant paint to prevent the transition step 550 itself from scratching the surface of the workpiece. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0035] In some embodiments, reference is made to Figure 4 The transitions between the sealing platform 300 and the transition step 550, and between the transition step 550 and the bottom of the receiving groove 500, are all rounded. The rounded transition structure can effectively reduce the sharp parts in the receiving groove 500, thereby effectively mitigating or avoiding the scratching of the workpiece by the internal structure of the receiving groove 500, so as to ensure that the workpiece has a more complete appearance.

[0036] In some embodiments, reference is made to Figure 3The housing 100 is provided with a positioning groove 400, which is used to accommodate and position the fixture 800. In use, this cover can support the bottom of the workpiece using a fixture, and the housing 100 can cover the top of the workpiece. The sealing platform 300, the shielding wall 600, and the enclosure wall 150 shield the sides of the workpiece, thus achieving a complete closure of the workpiece. To maintain the stability of the covering effect, the fixture 800 can be used to clamp the fixture, workpiece, and housing 100, preventing the housing 100 from falling off. The positioning groove 400 provides a positioning point for the fixture 800, allowing it to stably clamp the housing 100, thereby effectively improving the stability of the cover.

[0037] In some embodiments, reference is made to Figure 3 The positioning groove 400 and the receiving groove 500 are located on both sides of the housing 100. The positional relationship between the positioning groove 400 and the receiving groove 500 means that when the fixture 800 is installed in the positioning groove 400, the fixture 800 and the receiving groove 500 will be separated by the housing 100. Therefore, the fixture 800 can be effectively prevented from affecting the workpiece in the receiving groove 500, thereby avoiding damage to the workpiece.

[0038] In some embodiments, reference is made to Figure 3 There are multiple positioning grooves 400, and each positioning groove 400 is distributed along the length of the housing 100. The multiple positioning grooves 400 allow multiple clamps 800 to be installed on the housing 100, thus effectively clamping various parts of the housing 100 as a whole and preventing the housing 100 from tilting up in some areas.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
