A plurality of extended cylindrical steps are formed in parallel on the back surface of the second resin plate, and the light shielding layer covers the entire back surface of the second resin plate.

[0013]

【Example】

 Next, an embodiment of the resin molded product of the present invention is applied to a rear finisher for a vehicle and described with reference to the drawings.

FIG. 1 shows a resin molded product of the present invention, (A) is an enlarged perspective view of the main part, and (B) is a plan view of the same.

In FIG. 1, reference numeral 11 denotes a vehicle rear finisher (an overall view is omitted) as a resin molded product. The rear finisher 11 is disposed adjacent to a pair of left and right rear combination lamps (not shown).

Further, the rear finisher 11 is located outside the vehicle body, and the back surface of the first resin plate 12 made of a colored (eg, red) transparent resin and the surface of the second resin plate 13 made of a transparent resin are in close contact with each other. It is formed into a so-called skin-formed product, which is laminated in a thin plate shape in this state.

On the back surface of the first resin plate 12, a plurality of convex cylindrical steps 12a, 12a ... Which extend in the vertical direction are formed in parallel.

On the other hand, on the back surface of the second resin plate 13, a plurality of concave cylindrical steps 13a, 13a, ... Which extend in the lateral direction are formed in parallel. A thin film 14 as a light shielding layer is vapor-deposited on the back surface of the second resin plate 13 so as to cover the entire surface thereof.

By the way, this light-shielding layer is not limited to the thin film 14, and for example, as shown in FIGS. 2A and 2B, an opaque resin is laminated on the back surface of the second resin plate 13. The light blocking plate 24 may be used. In FIGS. 2A and 2B, the same components as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

Next, a method of forming the rear finisher 11 having such a configuration will be described. First, the first resin plate 12 is molded first. At this time, a plurality of convex cylindrical steps 12a, 12a ... That extend in the vertical direction are formed in parallel on the back surface of the first resin plate 12 at the same time.

Then, a molten resin is poured into the back surface of the first resin plate 12, the molten resin is cured, and the front surface of the second resin plate 13 is brought into close contact with the back surface of the first resin plate 12. The second resin plate 13 is laminated on the plate 12. At this time, a plurality of concave cylindrical steps 13a, 13a, ... Extending in the lateral direction are formed on the back surface of the second resin plate 13 in parallel at the same time.

At this time, when the second resin plate 13 is laminated on the first resin plate 12, the first resin plate 12 is attached to the resin molding die so that the extending directions of the steps 12a and 13a intersect each other. Pay attention to the installation direction when installing.

Then, from this state, the thin film 14 is vapor-deposited over the entire back surface of the second resin plate 13.

As described above, the resin molded product of the present invention is provided as a single plate-shaped product in which steps extending in a direction intersecting with each other are integrated while maintaining their shapes. In addition, it is possible to obtain a product that is suitable for products with limited wall thickness.

Accordingly, for example, when the resin molded product of the present invention is applied as a rear finisher arranged adjacent to a rear combination lamp at the rear of a vehicle, the light shielding film 14 serving as a light shielding layer prevents the resin molded product from the outside. Combined with the appearance's weight (depth feeling), it is possible to improve the visual sense of unity between the rear combination lamp and the rear finisher.

By the way, the heat resistance is higher than that of the material of the first resin plate 12 (for example, PET = polyethylene terephthalate) that is molded first, and the material of the second resin plate 13 (for example, PMMA = polymethacrylate / acrylic) that is molded later By using the excellent one, the original shape of the steps 12a, 12a, ... Of the first resin plate 12 previously molded is not destroyed by the heat of the molten resin of the second resin plate, and a stable refracting action is achieved. Can be secured.

In the above embodiment, the step 12a of the first resin plate 12 is formed into a convex cylindrical shape, and the step 13a of the second resin plate 13 is formed into a concave cylindrical shape. The unevenness direction of each step 12a, 13a is not limited.

Although the two-layer structure of the first and second resin plates 12 and 13 and the three-layer structure of the light shielding plate 24 are disclosed, at least two or more resin plates are laminated and any two of them are stacked. It is not applicable to various design changes made within the scope of the present invention, such as forming a plurality of cylindrical steps extending in a direction intersecting the back surface of the transparent resin plate in parallel. Of course.
