Description
Technical field
A kind of process modifications of auto parts and components are the utility model is related to, double-colored back light lens is specifically related to and adds
A kind of structure that work improves quality is improved.
Background technology
The structure of double-colored back light lens is to open up two pieces of rectangular openings, rectangular opening in the black frame of the nearly flat rectangle of black
The middle red tabular lampshade of insertion, in the plastics of black frame and the outer surface general injection covering layer of transparent of red tabular lampshade
Layer is as protection.It is rear vehicle lamp below red tabular lampshade, when red during brake, prompts, warning front vehicle.
The preparation method of current double-colored back light lens is that first injection makes black frame, then in the square of black frame
Second of shaping red colored lamp cover plate in shape hole.Third time injection is covered in black frame and the Transparent color of red colored lamp cover plate outer surface
Plastic layer, the injection directions of Transparent color plastics are to flow to red colored lamp cover plate direction by black frame, are the defects of prior art, thoroughly
High-temperature fusion when light colour plastic injection is processed, the material of a small amount of melting black framework in meeting part when flowing through black frame, and band
Enter with red colored lamp cover plate border, caused by consequence be that to have part at red colored lamp cover plate and black frame border be in black, produce
Raw to alter color problem, the black area and degree of the different dyes of operating mode are also different, have not only had a strong impact on the outer of double-colored back light lens
See, also need defence to influence red bright degree, influence its illumination and driving safety, it is therefore necessary to have behave change.
Utility model content
The utility model purpose, intend providing a kind of double-colored back light lens in manufacturing process, in injection Transparent color plastics
Process does not mix black frame material in the technical scheme at red colored lamp cover plate border edge.
The purpose of this utility model is realized by following technical scheme：
A kind of double-colored back light lens prevents from altering the structure of color, including the black frame of shaping and embedded black box for the first time
Second of red colored lamp cover plate shaped of frame rectangular opening, it is characterised in that：
Third time injection is covered in the Transparent color plastic layer of black frame and red colored lamp cover plate outer surface, by black frame stream
To red colored lamp cover plate direction, both borders while black frame side open up the rectangular indentation groove parallel with during border；
The depth of the rectangular indentation groove is 0.5-1.2mm, and width is 2-3mm.
Using the technical program, third time injection is covered in the Transparent color plastics of black frame and red colored lamp cover plate outer surface
Layer, when flowing to red colored lamp cover plate direction by black frame, the black frame plastics at border edge, and past red lamp shade are melted
Plate direction is flowed, and still, due to " both borders while black frame side open up the rectangular indentation groove parallel with during border ", melts
The black plastic melting material of change enters rectangular indentation groove, is blocked by the front end face of front side red colored lamp cover plate, it is impossible to flows into red
The upper surface of lampshade plate, no longer alters color, will not produce the defects of contaminating dark red lampshade plate border edge in the prior art.
Further, the depth of the rectangular indentation groove is 1mm, width 2.5mm.
The advantages of the utility model：One simple structural change, the black modeling melted in manufacturing process is thoroughly blocked
Expect that melting material enters the phenomenon of red colored lamp cover plate upper surface, overcome and solve dye dark red lampshade plate border edge in the prior art
Alter color defect.The presentation quality of double-colored back light lens is improved, has also guarded against traveling caused by influenceing red bright degree
Safety problem.

Arrow is covered in the injection flow direction of the Transparent color plastic layer of black frame and red colored lamp cover plate outer surface for third time injection.
In figure, 1 it is black frame, 2 is red colored lamp cover plate, 3 is Transparent color plastic layer, 4 is rectangular indentation groove.
Embodiment
Structure of the present utility model is further described below in conjunction with accompanying drawing.
A kind of double-colored back light lens prevents from altering the structure of color, including the black frame 1 of shaping and embedded black for the first time
Second of red colored lamp cover plate 2 shaped of the rectangular opening of framework 1, third time injection are covered in black frame 1 and the appearance of red colored lamp cover plate 2
The Transparent color plastic layer 3 in face, the direction of red colored lamp cover plate 2 is flowed to by black frame 1, the side of black frame 1 on both border sides opens up
The rectangular indentation groove 4 parallel with border side；
The depth of the rectangular indentation groove 4 is 0.5-1.2mm, and width is 2-3mm.
Third time injection Transparent color plastic layer 3, having melted the plastics of black frame 1 at border edge, to have flowed into rectangular indentation recessed
Groove, it is impossible to flow into the upper surface of red colored lamp cover plate 2, no longer alter color.It is computed and tests, rectangular indentation groove 4 is in as above scope
Desired effect can be obtained.
The depth of the rectangular indentation groove 4 is 1mm, width 2.5mm.
It is computed and tests, rectangular indentation groove 4 can obtains better effects in above-mentioned size.
