Abstract

(57) [Summary] [Purpose] To improve the aesthetics while omitting the conventional black coating process. [Structure] A pattern 3 is engraved on the black molding layer 2 on the back surface of the transparent molding layer 1 by laser cutting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multicolor translucent synthetic resin molded product such as a lighting button for audio equipment.

[0002]

[Prior art]

 With respect to such a molded article, the present application discloses a transparent molding layer 10 and a notch 12 formed by two-color molding as shown in FIGS. 3 and 4 in Japanese Patent Application Nos. 4-80462 and 4-81133. A black coating layer 13 is formed in the notch 12 of the black molding layer 11 on which the pattern is formed, and a pattern (for example, the letter A) 14 is engraved on the black coating layer 13 by laser cutting. A technique is proposed in which the pattern 14 can be visually recognized from the transparent molding layer 10 side by irradiation.

[0003]

[Problems to be solved by the device]

 The proposal itself is effective, but it requires a black coating step, and the boundary line 15 between the black coating layer 13 and the black molding layer 11 is visible from the surface, which is not aesthetically pleasing.

It is an object of the present invention to provide a multi-color translucent synthetic resin molded article that improves the aesthetics while omitting the conventional black coating process.

[0005]

[Means for Solving the Problems]

 According to the present invention, it is composed of a transparent molding layer and a black molding layer formed by molding two colors of a synthetic resin material, and a pattern engraved on the black molding layer by laser cutting.

The thickness of the black molding layer is preferably thin (for example, 0.2 to 0.3 mm).

[0007]

[Action]

 In the multicolor translucent synthetic resin molded product configured as described above, by engraving a pattern directly on the black molding layer by laser cutting, the conventional black coating layer coating process can be omitted, and It is possible to eliminate the boundary line between the conventional black coating layer and the black molding layer.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a black molding layer 2 having a thickness of, for example, 0.2 to 0.3 mm is provided on the back surface of the transparent molding layer 1, and the black molding layer 2 is patterned 3 (by laser cutting). The reference numeral 14 in FIG. 4) is engraved.

In manufacturing, as shown in FIG. 2, a transparent synthetic resin material and a black synthetic resin material are molded into two colors to form a transparent molding layer 1 on the front side and a black molding layer 2 on the back side. Then, the pattern 3 is engraved on the black molding layer 2 by laser cutting.

Therefore, the conventional coating process of the black coating layer 13 is unnecessary, and the conventional boundary line 15 is eliminated.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it is possible to reduce the cost by omitting the conventional black painting process and improve the aesthetic appearance by eliminating the conventional border line.
