FIG. 2 is a bottom view of a two-color product provided by an embodiment of the present invention;

in the figure: 1. a shooting piece; 2. a Film sheet; 3. two shooting pieces.

Detailed Description

The utility model is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in fig. 1, an embodiment of the present invention provides an injection molded product, which includes a first injection member 1 and a second injection member 3; one penetrates 1 upper surface and covers a layer Film sheet 2, when two penetrate 3 injection moulding in one and penetrates 1 upper surface, two of molten state penetrate 3 plastic particles and combine together with Film sheet 2, have avoided two of molten state to penetrate 3 plastic particles and directly penetrate 1 surface contact with one to ensure that one penetrates 1 surface and is not polluted, can obtain better product appearance effect, improve product quality.

As an embodiment of the utility model, the first injection piece 1 can adopt a homogeneous light diffusion plastic particle injection molding Lens structure, the second injection piece 3 can adopt a full transparent plastic particle injection molding Lens structure, and the middle part of the first injection piece 1 is provided with a window. To obtain a better light transmission effect, the light transmission of the two-ray element 3 is greater than ninety percent.

As shown in fig. 2, the first emitting member 1 and the second emitting member 3 may be both configured as a rectangular structure, and a rectangular opening, i.e., a window area, is formed in the middle of the first emitting member 1. One penetrates 1 the surface and is equipped with and stings flower or line structure, and it can increase one and penetrate 1 and the adhesion area of relevant structure to sting flower or line structure, increases the adhesive force to reach the environmental test requirement, and it is more pleasing to the eye that the yield that helps injection moulding product promotes and the outward appearance effect to sting flower or line structure.
