A spraying tool for the interior guard plate of the automobile rear door

Abstract

The invention discloses a tool for spraying a car rear door trim protecting plate and belongs to the technical field of spraying tools. When the tool is used to spray paint on the car rear door trim protecting plate, a vertical spraying manner is adopted. When the car rear door trim protecting plate is fed into a drying workshop for high-temperature drying after paint spraying, the plastic plate at the bent part at the upper end of the rear door trim protecting plate is cooled, and the plastic plate is allowed to be less prone to buckling deformation. A left window rack and a right window rack are fixedly connected to the lower end of a lifter, an upper transverse rod tube cavity is formed in the upper transverse rod along the axis of each of the left window rack and the right window rack, and the two tube cavities are communicated. The tool further comprises a drive thrust tube, a driven thrust tube and a cooling water reflux cylinder. A sealed space formed by the upper transverse rod tube cavities, a first communicating tube, a second communicating tube and the drive thrust tube is filled with mercury or ethanol. A sealed space formed by the cooling water reflux cylinder, a hose and the driven thrust tube is filled with cooling water in a sealed manner.

Description

technical field [0001] The invention relates to the technical field of spraying tooling, in particular to a tooling for spraying the trim guard plate of an automobile rear door. Background technique [0002] With the improvement of people's requirements for automobile interior decoration, automobile manufacturers have begun to spray the surface of the rear door interior trim panel of many models. In the spraying production process of the surface of the rear door trim panel, the surface of the rear door trim panel needs to be sprayed first, and then the painted rear door trim panel is sent to the baking workshop for high-temperature baking. Since the rear door interior guard plate is generally made of plastic material, the plastic is prone to warping and deformation during the high-temperature baking process, which affects the product assembly clearance.

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that if the existing spraying device sprays the car rear door trim guard plate, when the rear door trim guard plate is sent to the baking workshop for high-temperature baking, due to the effect of tension, the rear door trim tends to appear. The bending degree of the plastic plate at the upper bending part of the guard plate becomes smaller, which causes warping and deformation of the plastic plate at the upper bending part of the rear door trim guard plate, which affects the lack of product assembly clearance. When painting, use the vertical method of the rear door trim panel to spray paint, and send it to the baking workshop for high-temperature baking after the rear door trim panel is painted, and use the cooling method to cool the plastic of the bent part of the rear door trim panel. The panel is cooled, so that the plastic plate at the upper part of the rear door trim panel is not easy to warp and deform, and the spraying quality is high, and the baking quality is a spraying tool for the automotive rear door trim panel.
