Description
Technical Field
The invention relates to an improvement of a processing method of automobile parts, in particular to a structural improvement for improving the processing quality of a bicolor rear lamp lens.
Background
The structure of the double-color rear lamp lens is that two rectangular holes are formed in a black frame which is black and is approximately flat and rectangular, a red platy lampshade is embedded in the rectangular holes, and a transparent plastic layer is integrally injected and covered on the outer surfaces of the black frame and the red platy lampshade to serve as protection. The rear car lamp is arranged below the red platy lamp shade, and the red lamp is lightened during braking to prompt and warn the rear car.
The current manufacturing method of the double-color rear lamp lens is to firstly manufacture a black frame by injection, and then to form a red lamp cover plate for the second time in a rectangular hole of the black frame. The third injection covers the transparent plastic layer on the outer surface of the black frame and the red lampshade plate, the injection direction of the transparent plastic is from the black frame to the red lampshade plate, the defect in the prior art is that the transparent plastic is melted at high temperature when flowing through the black frame, and the transparent plastic can partially melt the material of the black frame when flowing through the black frame, but is brought into the junction with the red lampshade plate, the result is that the junction of the red lampshade plate and the black frame is partially black, the color channeling problem is generated, the areas and the degrees of the black dyed under different working conditions are different, the appearance of the double-color rear lamp lens is seriously influenced, the red brightness is also required to be prevented, the illumination and the driving safety are influenced, and therefore, the measures are required to be changed.
Disclosure of Invention
The invention aims to provide a technical scheme that black frame materials are not mixed at the junction edge of a red lampshade plate in the process of injecting transparent plastics in the manufacturing process of a bicolor rear lamp lens.
The aim of the invention is realized by the following technical scheme:
the utility model provides a double-colored rear lamp lens prevents structure of scurrying colour, includes black frame and the red lamp shade board of embedding black frame rectangular hole second time shaping of first time, its characterized in that:
injecting a transparent plastic layer covering the outer surfaces of the black frame and the red lampshade plate for the third time, and flowing the black frame to the direction of the red lampshade plate, wherein rectangular notch grooves parallel to the junction edges are formed in the black frame side of the junction edges;
the depth of the rectangular notch groove is 0.5-1.2 mm, and the width is 2-3 mm.
By adopting the technical scheme, the third injection covers the transparent plastic layer on the outer surfaces of the black frame and the red lampshade plate, when the black frame flows to the direction of the red lampshade plate, the black frame plastic at the junction edge is melted and flows to the direction of the red lampshade plate, but because the rectangular notch groove parallel to the junction edge is formed on the black frame side of the junction edge of the black frame and the red lampshade plate, the melted black plastic melt enters the rectangular notch groove and is blocked by the front end surface of the front side red lampshade plate, and cannot flow into the upper surface of the red lampshade plate, color channeling is avoided, and the defect of dyeing the junction edge of the black lampshade plate in the prior art is avoided.
Further, the depth of the rectangular notch groove is 1mm, and the width of the rectangular notch groove is 2.5mm.
The invention has the advantages that: a simple structure is changed, the phenomenon that melted black plastic melt material enters the upper surface of the red lamp housing plate in the manufacturing process is thoroughly blocked, and the color shifting defect of the junction edge of the black-dyed red lamp housing plate in the prior art is overcome and solved. The appearance quality of the double-color rear lamp lens is improved, and the running safety problem caused by the influence on the red light transmittance is also solved.

Detailed Description
The structure of the present invention is further described in detail below with reference to the accompanying drawings.
The structure for preventing color channeling of the bicolor rear lamp lens comprises a black frame 1 formed for the first time and a red lampshade plate 2 embedded in a rectangular hole of the black frame 1 and formed for the second time, wherein a transparent plastic layer 3 covering the outer surfaces of the black frame 1 and the red lampshade plate 2 is injected for the third time, the transparent plastic layer flows from the black frame 1 to the red lampshade plate 2, and rectangular notch grooves 4 parallel to the junction edges are formed on the sides of the black frame 1 at the junction edges of the black frame 1 and the red lampshade plate 2;
the depth of the rectangular notch groove 4 is 0.5-1.2 mm, and the width is 2-3 mm.
And the transparent plastic layer 3 is injected for the third time, the plastic of the black frame 1 which melts the border edge flows into the rectangular notch groove, cannot flow into the upper surface of the red lamp housing plate 2, and does not cross color. The rectangular notch groove 4 can achieve the expected effect in the above range through calculation and test.
The depth of the rectangular notch groove 4 is 1mm, and the width is 2.5mm.
Through calculation and test, the rectangular notch groove 4 can achieve good effect in the above dimension.
