くとも0.5mm以上の段差を取るのが普通であつた。Conventional technology In the past, decorative parts such as letters and patterns were added to parts of molded products made of synthetic resin, etc., to further increase the durability of the molded products and to improve the appearance by covering weld marks and flow marks. In order to
When making a decorated molded product with paint applied to areas other than the decorative part of the molded product, first plate the entire surface of the molded product, then mask the decorative part and paint the entire surface. was taken. In this case, in order to separate the masked decorative parts such as letters from the painted surface, it was common to have a step difference of at least 0.5 mm between the two.

ツプにつがるという欠陥があつた。 However, in this method, it was necessary to form a step between the decorated part and the painted surface, so the surface of the finished decorated molded product lacked a sense of unity. Also,
This method has the disadvantage that even if only a portion of the decorative molded product is to be formed with a plating-like decorative portion, the entire molded product must be plated, which increases the cost of the product.

形成して加飾体７を形成する。EXAMPLE Hereinafter, an example embodying the present invention will be described with reference to the drawings. First, a decorative body 1 made of synthetic resin or rubber as shown in FIG. Decoration part 2 such as letters and patterns
are formed in a protruding manner, and leg portions 3 are formed in a protruding manner on the lower surface. Next, as shown in FIG. 1b, a masking 4 is formed on the upper part of the decorative portion 2 by nickel electroforming,
As shown in FIG. 1c, a coating film 5 made of acrylic vinyl chloride resin is formed on the surface of the decoration main body 1, and then, as shown in FIG. 1d, the masking 4 is removed, and then as shown in FIG. As shown in e, a plating film 6 made of metal such as chromium is formed on the exposed decorative portion 2 to form a decorative body 7.

体７の加飾面９が露出することになる。 Next, as shown in FIG. 2, this decorative body 7 is set and insert-molded so that the upper surface of the plating film 6, that is, the decorative surface 9, is in contact with the lower surface of the upper die 8 of an injection molding die. When setting the decorative body 7, the decorative body 7 is fixed to the cavity 11 of the lower die 10 with double-sided adhesive tape or positioning pins. When insert molding is performed in this manner, the decorative surface 9 of the decorative body 7 is exposed on the surface of the molded product main body 12, as shown in FIGS. 3 and 4.

の分離が起こりにくくなる。 A decorative molded product is formed as described above,
In the present invention, since the decorative surface 9 of the decorative body 7 and the upper surface of the molded article main body 12 are flush with each other, the sense of unity of the upper surface of the decorated molded article can be improved. In addition, in the present invention, by partially providing the plating film 6 on the decorative portion 2 of the decorative main body 1, the resin Since the boundary between the decorative body 1 made of molded product and the molded product body 12 is similarly coated with a resin coating 5, the adhesion is improved. By repeating the thermishing test, in the case of a fully plated product, separation is likely to occur at the boundary between the top surface of the decorative body 1 and the molded product body 12, but in the case of a partially plated product, the plated part is close to the top surface of the decorative part 2. However, if the depth is 0.5 to 1 mm, separation at the boundary will be less likely to occur.

ができるのである。 Furthermore, a plating film 6 is provided on the back surface of the decorative main body 1 of the present invention.
Since there is no exposure, products such as moldings can be easily adhered with double-sided adhesive tape. On the other hand, in the case of a fully plated product, adhesion between the resin and chrome plating film and the adhesive tape is required, so there is a problem in the performance reliability of the adhesive tape used for both metal and resin. In addition, the partially plated product of the present invention can reduce the amount of the plating film having a large specific gravity, and as a result, the weight of the product can be reduced.

Consisting of a plating film partially applied to the surface of the decorative portion and a molded product body into which the decoration body is insert-molded, the surface of the molded product body and the surface of the plating film are flush with each other. By forming this, it is possible to improve the sense of unity between the decorative surface appearing on the surface of the decorative molded product and other surfaces, and also to increase durability, further reducing weight and cost. This has the effect of making it possible to achieve this goal.
