Description

Technical Field

[0001] This utility model relates to the field of automotive plastic parts spraying technology, specifically to a spraying support fixture for automotive plastic parts. Background Technology

[0002] Currently, the common method for painting plastic parts in the automotive industry is to classify the plastic parts (for example, bumpers, license plate panels, bumper trim panels, rear panel trim panels, and door handles), and then paint them in batches according to category. This method is suitable for production lines with mature production processes and large production volumes. These production lines are equipped with computer-controlled paint mixing, painting, and drying equipment, and paint the same parts on the car together. Its advantage is that the mixed paint color is consistent and the color is fast, but the investment required is quite huge.

[0003] A search revealed that patent application number 201520972399.X discloses a spraying support fixture for automotive plastic parts, including a support frame. The support frame has a license plate bracket, a front bumper bracket, a door handle and end cover bracket, a rear trim panel bracket, a rear bumper bracket, and a rearview mirror cover bracket distributed on its end face. This fixture can spray all the plastic parts of the car together, and has a simple structure and is easy to manufacture.

[0004] The aforementioned application documents achieve top mounting of various plastic parts on the top side through the setting of various frames on the tooling. However, it is a fixed structure and requires the customization of tooling frames of corresponding specifications. However, it has poor flexibility and cannot support and limit the plastic parts of corresponding specifications according to the requirements.

[0005] Therefore, we propose a spraying support fixture for automotive plastic parts. Utility Model Content
