Description
Technical field
The present invention relates to automobile lamp multi-color injection molded part injection molding technology fields, in particular to a kind of by rationally dividing
Layer solves the method for multi-color injection molded part colour mixture defect, a kind of multi-color injection molded part, a kind of automobile lamp.Pass through more particularly to one kind excellent
Change the layered structure of multi-layer injection molding part, improves the method for colour mixture defect and a kind of multi-color injection molded part in polychrome part injection moulding process
And the automobile lamp using it.
Background technique
With the factor of the various aspects such as the continuous development of novel injection molding technology and customer demand, moulding, luminous intensity distribution performance,
The multi-color injection molded use in car light industry is increasingly extensive.In general, color is known as polychrome more than two or more mouldings
Moulding.The problem of moulding monochromatic for routine, injection raw material only has one kind, is not present with other color colour contamination, colour mixture.
But present inventor has found, for multi-color injection molded molding, especially injection molding (dispensable mould) for the first time be light color not
Hyaline layer, it is the multi-color injection molded of fully transparent layer that second, which is molded (quadratic form), after dispensable mould molding, quadratic form injection molding material meeting
It is flowed in an injection molded layers, the temperature flowing melt of quadratic form by the first color remelting and can be rushed out its original position (such as
Shown in Fig. 1), lead to the open defect that colour mixture is formed at product layering, it is final to influence product appearance and light distributing function.
Therefore, how to provide a kind of by being rationally layered the method for solving multi-color injection molded part colour mixture defect, a kind of polychrome note
Plastic, a kind of automobile lamp can improve and eliminate the colour mixture defect of multi-color injection molded part, it has also become those skilled in the art are urgently
Technical problem to be solved.
Summary of the invention
It is an object of the present invention to provide a kind of by being rationally layered the method for solving multi-color injection molded part colour mixture defect,
It is easy there is technical issues that colour mixture to solve existing multi-color injection molded part.
The present invention provides a kind of by being rationally layered the method for solving multi-color injection molded part colour mixture defect, includes the following steps：
One layer of isolation hyaline layer is added between dispensable mould layer and quadratic form layer；It is first molded the isolation hyaline layer, then is molded described one
Secondary type layer is finally molded the quadratic form layer.
It is of the present invention by being rationally layered in the method for solving multi-color injection molded part colour mixture defect when practical application, institute
Stating dispensable mould layer is in light opaque layer；The transparent layer of quadratic form layer.
Wherein, of the present invention by being rationally layered in the method for solving multi-color injection molded part colour mixture defect, the light color
Opaque layer uses non-black material.
Specifically, of the present invention by being rationally layered in the method for solving multi-color injection molded part colour mixture defect, it is described to be in
When the quadratic form layer of hyaline layer impacts the isolation hyaline layer, the appearance of the multi-color injection molded part is still transparent.
