Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a colored molding in which a pattern such as three colored characters and nine figures is formed, and a method for manufacturing the same.

[Prior art]

BACKGROUND ART Moldings are attached to the side surfaces of automobiles for decoration and protection.

In order to further improve the decorativeness of the molding.

In recent years, colored moldings with patterns such as one colored letter and one figure have been used.

As shown in FIG. 16, the conventional colored molding 9 has a p! ! It was manufactured by forming a pattern 92 such as a 0 character with a cover. The coloring state of this colored mall 9 is 1
For example, the molding body 91 is painted black, and the pattern 92 is painted red, white, or the like.

[Problem to be solved]

However, in the conventional colored molding, when forming the pattern, a mask having holes formed in the same shape as the pattern is used, and paint is applied from above the mask.

Therefore, it is necessary to fix the mask so that it does not move during painting. In addition, especially when forming a linear pattern, if the mask is not properly positioned properly, deformed lines such as three curves or uneven lines may be formed. Furthermore, if characters, etc. are to be formed in a straight line on the molding body, the inclinations, etc. of the eight characters may not match.

As described above, it has been difficult to form patterns using conventional manufacturing methods.

Also, the pattern is formed on a part of the molding,
When painting, it is necessary to completely mask the non-pattern forming areas.

The cost will be high.

Further, the painting requires heating, but when the molding body is made of a soft synthetic resin, this heating causes the molding to be deformed or warped.

Furthermore, there is a risk that the painted pattern may peel off at its periphery during car washing or the like.

In addition, as another method of manufacturing the two-colored molding, there is also a method of pasting a colored tape on the molding body. However, in this case, considerable skill is required to adhere, for example, a linear colored tape in a straight line or to adhere a pattern such as a single letter in a straight line. Also.

There is also a risk that the colored tape 7 may peel off during long-term use or during cleaning.

In view of these conventional problems, the present invention allows the same pattern to be easily formed without causing peeling of the pattern portion and without causing deformation or warping of the molding body during pattern formation.

It is an object of the present invention to provide a colored molding and a method for manufacturing the same.

Coated with various coating methods such as dip coating. The periphery of the patterned portion is covered with a decorative material.

Further, as the colored member, 1, for example, oil-based paint powder paint,
Various types of water-resistant paints are used, such as adhesive paints, UV-cured paints, and electron beam-cured paints. In addition, its coloring is white, yellow,
Red, blue, green, gold, etc. can be any color.

In addition, the thickness of the above-mentioned colored paint is preferably 0.01 to 0.5 m from the viewpoint of durability and strength during use.

Further, the pattern portion may be any combination of letters and figures, and one or more colors may be used. When using multiple types of colors, for example, multiple colored members are used.

Further, a pattern such as nine characters is formed by covering the periphery of the pattern portion in a predetermined shape with a design material.

Further, the pattern is provided at an arbitrary height, such as on the same plane at a location lower than the surface of the design material, or at a location higher than the surface of the design material (see FIGS. 3 to 5).

In addition, the method for manufacturing the above-mentioned colored molding is as follows: coat the front side of a core plate made of metal 2 synthetic resin with a colored member to create a decorative plate, then place the decorative plate in a mold, and place the decorative plate inside the mold. A method of supplying a decorative material to a surface of the decorative board other than the pattern-forming portion on the surface of the colored member, and coating the decorative board with the decorative material on the patterned portion of the colored member. There is a method for manufacturing a colored molding characterized by having a patterned surface that does not cause coloring.

What is most noteworthy about this method is that the mold is provided with a bottomed pattern surface to prevent the design material from adhering to the pattern-forming portion of the surface of the pattern, and the decorative plate is placed inside the mold. It is to supply the design material into the mold.

The above-mentioned patterned surface has a structure that prevents the design material from penetrating into the inside of the pattern.1 For example, the patterned surface is in full contact (zero contact) with the surface of the colored member on the patterned part (Fig. 13). be. Alternatively, a convex adhesion surface (weir) is formed in a portion corresponding to the outer periphery of the pattern! There is Mr. a (Figure 14).
