ある。The molding die of the present invention is obtained by polishing the surface of the metal and/or ceramic sprayed coating layer thus formed. In general, the surface of the coating obtained by thermal spraying metals and/or ceramics becomes the mold base.In unfired IJ+, the surface of the sprayed coating layer on the mold base is polished to make the surface rough. It is preferable to set the center line roughness (Ra value) to 1.0 to 3.6, particularly 2.0 to 3.6 islands.

は、成形品の表面に空気溜が多発するのて好ましくない
．また過度に粗い場合には，研摩の効果か少なく、光沢
肌か得られない。If the surface roughness of the mold surface after polishing is too fine, this is undesirable because air pockets will occur frequently on the surface of the molded product. Also, if the surface is too rough, the polishing effect will be low and a glossy surface will not be obtained.

なお、成形用金型における溶射皮膜層の形成位置として
は、金型成形面の少なくとも一部の耐摩耗性か必要とさ
れる部分が含まれていればよく。The sprayed coating layer may be formed at a position in the molding die as long as it includes at least a part of the molding surface where wear resistance is required.
具体的には金型のはぶち部分等が例示される。A specific example is the edge of a mold.

い型子地肌の成形品が得られるにすぎなかった。[Function] Conventional molding molds with a metal and/or ceramic sprayed coating layer on the L& shape surface have excellent abrasion resistance on the molding surface, but when molded with rubber or plastic, the mold becomes dull. Only a bare molded product was obtained.
これに対し１本発明においては金型の成形面に形成され

沢を有する。In contrast, in the present invention, the surface of the sprayed coating layer formed on the molding surface of the mold is polished, thereby providing a surface with a plurality of small protrusions each having a flat tip. Therefore, unlike the surface of the mold, where light is diffusely reflected, the flat parts reflect light in a certain direction, giving it a glossy appearance.
従って、本発明の金型によりゴムやプラスチックスな成
形すると１表面に光沢を有するゴムやプラスチックスの
成形品か得られる。Therefore, when rubber or plastic is molded using the mold of the present invention, a molded product of rubber or plastic that has gloss on one surface can be obtained.
