[0002] In the production of automotive trim parts, spraying is an essential process. During spraying, areas that need to be precisely masked to preserve their original color, pattern, or material are protected from deformation or damage caused by paint coverage. Chinese Patent Publication No. CN219723323U discloses an automotive parts spraying device that eliminates manual spraying, prevents paint from splattering onto other surfaces of the parts, improves the uniformity of paint application, and further enhances both paint quality and the overall production quality of the parts.

[0003] Although the aforementioned existing technology uses a covering cloth for shielding, it still has the following problems:

[0004] The edges of the masking cloth are prone to burrs, which can cause paint seepage during spraying, making it difficult to guarantee the masking effect. This affects product quality and production efficiency. Furthermore, after a period of use, the masking cloth may experience wear and deformation, requiring regular replacement, which is inconvenient, time-consuming, and labor-intensive.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The present invention will be further described below with reference to specific embodiments:

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment of an automotive trim spraying masking structure includes a masking base 1 and a masking mold 2. The masking base 1 is installed on a spraying device, and the automotive trim is fixed by a trim fixing platform 3 on the surface of the masking base 1. The masking mold 2 is set above the trim fixing platform 3. A transmission screw 11 and a guide rod 12 are diagonally arranged on the masking base 1. The upper ends of the transmission screw 11 and the guide rod 12 are fixedly connected to a limiting ball 13 by bolts. The lower surface of the transmission screw 11 penetrates the surface of the masking base 1 and is rotatably connected to the masking base 1 by a pin. A drive motor 15 is installed inside the masking base 1. The output shaft of the drive motor 15 is fixedly connected to the driving wheel in the transmission gear set 14. A driven wheel that meshes with the driving wheel is installed at the lower end of the transmission screw 11. The drive motor 15 drives the transmission gear set 14 to rotate, thereby rotating the transmission screw 11. With the guidance of the guide rod 12, the masking mold 2 moves up and down.

[0025] When the shielding mold 2 needs to be replaced, the limit ball 13 is removed and the drive motor 15 drives the shielding mold 2 to move upward until the guide sleeve 21 is separated from the transmission screw 11, which is convenient for disassembly;

[0026] The trim fixing platform 3 can be detachably installed on the masking base 1. By replacing the trim fixing platform 3 and the corresponding masking mold 2, it can be adapted to different automotive trim painting processes.

[0027] Example 2

[0028] To better utilize the masking mold 2 and effectively prevent excess spray liquid from dripping and affecting the spraying effect, refer to... Figures 2-3 As shown, based on the above embodiment, guide sleeves 21 are installed around the shielding mold 2. The guide sleeves 21 are respectively sleeved with the transmission screw 11 and the guide rod 12. The inner side of the guide sleeve 21 is provided with an internal thread that is compatible with the transmission screw 11. The guide sleeves 21 at one corner are engaged with the transmission screw 11 through the internal thread, and the guide sleeves 21 at the other corner slide up and down on the guide rod 12. A shielding positioning frame 22 is provided on the lower surface of the shielding mold 2.

[0029] The surface of the masking mold 2 is provided with a spraying groove, the inner wall of the masking positioning frame 22 is consistent with the shape of the spraying groove, and the lower surface of the masking positioning frame 22 is provided with a sealing strip to ensure that the masking mold 2 can effectively cover the non-spraying area of ​​the automotive trim. The upper surface of the masking positioning frame 22 is provided with a positioning pin 23, and the lower surface of the masking mold 2 is provided with a positioning groove corresponding to the positioning pin 23. A first spring 24 is fixedly installed on the upper end of the positioning pin 23, and the first spring 24 is fixedly connected to the positioning groove.

[0030] Through the cooperation of the transmission screw 11 and the guide rod 12, the shielding mold 2 is positioned to the part of the car trim that needs to be shielded. The positioning pin 23 on the shielding positioning frame 22 is inserted into the positioning groove on the lower surface of the shielding mold 2, and the first spring 24 provides pre-tightening force to ensure that the shielding mold 2 and the shielding positioning frame 22 fit tightly together to prevent the spray liquid from leaking.

[0031] The inner wall of the masking positioning frame 22 is set as an inclined slope, and a water collection ditch 25 is set at the lower end of the slope. The water collection ditch 25 is used to collect the spray liquid dripping during the spraying process, and the spray liquid dripping in the water collection ditch 25 is discharged manually to prevent the spray liquid from dripping onto the car trim and affecting the spraying effect.

[0032] Specifically, in this embodiment, by setting a sealing strip, a ramp, and a water collection ditch 5 on the masking positioning frame 22, the problem of spray liquid leakage in traditional spray masking structures is effectively solved, spraying efficiency and quality are improved, and significant beneficial effects are achieved.

[0033] Example 3

[0034] To further improve the accuracy of the spraying area and the spraying effect, please refer to [link / reference needed]. Figures 3-4 This embodiment includes a fixing plate 32 for clamping and fixing automotive trim parts.

[0035] Specifically, the surface of the trim fixing platform 3 is provided with a placement groove 31 adapted to the automotive trim for placing the trim. A fixing clamp 32 is provided in the placement groove 31 to hold the automotive trim. The translation guide 33 is adapted to the translation groove 34 provided on the surface of the placement groove 31 and is fixedly connected to the fixing clamp 32 by a second spring 35. The second spring 35 is used to provide pre-tightening force so that the fixing clamp 32 fits tightly with the automotive trim. One side of the fixing clamp 32 is fixedly connected to the telescopic rod 36 by bolts. Anti-slip protrusions 37 are provided on the other side of the fixing clamp 32 to increase friction and prevent the automotive trim from sliding during the spraying process.

[0036] The second spring 35 provides pre-tension, and the fixing plate 32 can automatically adjust the clamping force according to the shape and size of the automotive trim, ensuring that the trim is stably fixed during the spraying process. The anti-slip protrusion 37 increases friction and prevents the automotive trim from sliding during the spraying process, which can effectively solve the problem of deformation or displacement of automotive trim during the spraying process and improve the spraying quality and efficiency.
