成形品の表面を確実に艶消しすることができる。(Effects of the Invention) As described above, according to the surface matte molding method for a synthetic resin molded product according to the present invention, a molded product model is coated with a substance such as a paint containing a large number of fine particles and then electroformed. To do. And
The above-mentioned molded product model is used as a master mold, and the master mold is molded by this master mold. Since the surface of the molded product model is rough, the entire inner surface of the molding die is also rough. Therefore, it is possible to surely deluster the surface of the molded product molded using the molding main mold.
また、上記成形法によれば成形品の一部を艶消しするこ
ともできるほか、成形が容易で、且つ経済的でもある。Further, according to the above-mentioned molding method, a part of the molded product can be delustered, and the molding is easy and economical.
（実施例） 以下、図面によって本発明に係る合成樹脂製成形品の表
面艶消し成形法の一例について説明する。(Example) Hereinafter, an example of a surface matt molding method for a synthetic resin molded article according to the present invention will be described with reference to the drawings.

が形成される。That is, as shown in FIG. 1 (a), a large number of fine particles 2a are formed on the surface of a molded article model 1 formed by imitating the doll's arm.
A coating 2 containing 2a ... Is applied and then electroformed to form a master mold A. The molded product model 1 is not limited to synthetic resin, and may be made of metal, glass, wood, or the like. Alternatively, an adhesive may be applied to the surface of the molded product model 1, and a large number of fine particles may be sprinkled on the surface of the adhesive to adhere them, followed by electroforming. Next, as shown in FIG. 1B, the master mold A is formed by a predetermined means using the master mold A, and then the master mold A is removed from the mold main mold 3. As a result, the surface 3 of the main molding die 3 is finally roughened 3a, and the completed main molding die 3 is finished.
Is formed.
