It is composed of a first injection product 10 made of material, a second injection product 20 made of urethane material, a concave indentation portion 30 of a concave shape, and a metal ink layer 40 coated with ink.

즉, 상기 제1사출물(10)은 상측에 문양과 문자가 표시되는 음각천공부(11)가 천공되고, 상면에는 하도와 상도로 코팅되는 코팅층(12)이 형성되어 상기 제1사출물(10)을 보호하게 된다.That is, the first injection (10) is perforated intaglio perforated portion 11 is displayed on the upper side and the pattern and letters, the upper surface is formed with a coating layer 12 is coated with a channel and the upper surface of the first injection (10) To protect.

그리고, 상기 제2사출물(20)은 상기 제1사출물(10)의 하면과 일체로 결합되도록 우레탄재질로 형성되며, 상기 음각천공부(11)의 하측이 폐쇄되도록 일체로 사출 결합되고, 상기 제2사출물의 상면에는 상기 제1사출물(10)과 밀착되도록 접착재(21)가 도포된다.And, the second injection 20 is formed of a urethane material so as to be integrally coupled with the lower surface of the first injection 10, injection molded integrally so that the lower side of the negative hole (11) is closed, The adhesive 21 is coated on the upper surface of the second injection molding to be in close contact with the first injection molding 10.

도 2 및 도 3에서, 상기 제1사출물(10)과 제2사출물(20)을 결합시 상기 음각천공부(11)의 하측이 폐쇄되어 요입형상의 음각요입부(30)가 형성된다.In FIGS. 2 and 3, when the first injection 10 and the second injection 20 are combined, a lower side of the intaglio perforation 11 is closed to form a recess indentation 30.

또한, 상기 메탈잉크층(40)은 상기 음각요입부(30)의 내부에 메탈감이 나타나도록 외장용 잉크로 도포된다.In addition, the metal ink layer 40 is coated with an exterior ink so that a metallic feeling appears inside the engraved portion 30.

한편, 휴대폰 외장품의 음각구조의 제조방법은 문양이 천공된 음각천공부(11)가 형성된 PC재질의 제1사출물(10)을 성형하는 제1사출물성형공정(S1)과, 상기 제1사출물(10)의 하측과 결합되는 제2사출물(20)을 성형하는 제2사출물성형공정(S2)과, 상기 제1사출물(10)과 제2사출물(20)을 일체로 결합시켜 이중사출물을 성형하는 결합사출공정(S3)과, 상기 이중사출물의 표면에 상도와 하도를 코팅하는 코팅공정(S4)과, 상기 음각요입부(30)의 내부에 메탈감이 형성되도록 잉크로 도포되는 잉크도포공정(S5)으로 구성된다.On the other hand, the manufacturing method of the intaglio structure of the mobile phone exterior article is a first injection molding process (S1) for molding the first injection molding material 10 of the PC material formed with the negative hole punched portion 11 is patterned and the first injection ( The second injection molding process (S2) for molding the second injection 20 to be combined with the lower side of 10), and the first injection 10 and the second injection 20 are integrally combined to form a double injection Combined injection step (S3), the coating step (S4) for coating the top and bottom coating on the surface of the double injection, and the ink coating step that is applied with ink to form a metal feeling inside the intaglio (30) S5).

또한, 제1사출물(10)을 성형하는 제1사출물성형공정(S1)과, 상기 제1사출물(10)의 하측과 결합되는 제2사출물(20)을 성형하는 제2사출물성형공정(S2)과, 상기 제1사출물(10)과 제2사출물(20)을 일체로 결합시켜 이중사출물을 성형하는 결합사출공정(S3)은 하나의 공정에서 제1사출물(10)과 제2사출물(20)을 결합하여 이중사출물을 성형하는 것도 바람직하다.
In addition, the first injection molding process (S1) for molding the first injection 10, and the second injection molding process (S2) for molding the second injection 20 to be coupled to the lower side of the first injection (10). And, the combined injection process (S3) for forming a double injection by combining the first injection 10 and the second injection 20 integrally, the first injection 10 and the second injection 20 in one process It is also preferable to form a double injection by combining.

다음은 상기와 같은 구성을 가지는 본 발명인 휴대폰 외장품 음각구조의 작용에 대하여 기술한다.The following describes the operation of the intaglio structure of the present invention mobile phone having the configuration as described above.

본 발명에 의한 휴대폰 외장품의 음각구조는, 도 2 및 도 3에 도시된 바와 같이, 휴대폰의 사이드키나 커버외장에 음각으로 문양과 문자를 구현하는 외장품음각구조에 사용된다.The intaglio structure of the cellular phone exterior article according to the present invention, as shown in Figs. 2 and 3, is used in the exterior article intaglio structure that embodies the patterns and characters in the intaglio on the side key or the cover of the mobile phone.

즉, 제1사출물(10)의 상면에 문양과 문자가 표시되는 음각천공부(11)가 음각으로 천공되고, 상기 제1사출물(10)과 우레탄 재질의 제2사출물(20)을 일체로 결합하면 음각천공부(11)의 하측이 폐쇄되어 요입형상의 음각요입부(30)가 형성된다. 이때, 상기 음각요입부(30)에 외장용 잉크로 도포되는 메탈잉크층(40)이 형성됨으로써 잉크의 다양한 색상이 음각으로 구현되어 휴대폰의 외관미를 더욱 향상시킬 수 있는 된다. That is, the intaglio perforated part 11, which has a pattern and a letter on the upper surface of the first injection product 10, is intaglio perforated, and the first injection product 10 and the second injection product 20 made of urethane are integrally combined. The lower side of the intaglio perforated part 11 is closed to form a concave indentation portion 30 having a concave shape. In this case, since the metal ink layer 40 coated with the external ink is formed on the intaglio injecting part 30, various colors of the ink may be embossed to further improve the appearance of the mobile phone.

그리고, 상기 제1사출물(10)은 PC재질로 형성되고, 상기 제2사출물(20)은 우레탄재질로 형성되어 일체로 결합하면 요입형상의 음각요입부(30)가 형성됨으로써 종래에 다수개의 사출물을 결합하여 음각천공부를 형성하던 구조가 콤팩트되어 공정을 간소화하여 생산성을 대폭 증가시킬 수 있으며, 종래에 음각을 형성하기 위하여 사용되던 도금공정이 불필요하게 되어 친환경적인 제품을 생산할 수 있게 된다.In addition, the first injection 10 is formed of a PC material, the second injection 20 is formed of a urethane material is formed by the urethane material is formed in the concave indentation portion 30 of the concave shape in the prior art by a plurality of injection molding Combining the structure to form the intaglio perforation can be compact to greatly increase the productivity by simplifying the process, and the plating process used to form the intaglio conventionally becomes unnecessary to produce an environment-friendly product.

또한, 상기 제1사출물(10)의 상면에는 하도와 상도로 코팅되는 코팅층(12)이 형성됨으로써 제1사출물(10)의 표면이 코팅되어 휴대폰의 외장의 표면이 광택을 발휘할 수 있으며 충격으로부터 보호할 수 있게 된다.In addition, the upper surface of the first injection 10 is formed with a coating layer 12 is coated with a channel and a top, so that the surface of the first injection 10 can be coated to exhibit a glossy surface and protect from impact You can do it.

그리고, 제1사출물(10)을 성형하는 제1사출물성형공정(S1)과, 상기 제1사출물(10)의 하측과 결합되는 제2사출물(20)을 성형하는 제2사출물성형공정(S2)과, 상기 제1사출물(10)과 제2사출물(20)을 일체로 결합시켜 이중사출물을 성형하는 결합사출공정(S3)을 단일공정으로 구현함으로써, 공정이동이 불필요하며 작업손실이 최소화되어 생산성을 대폭 향상시킬 수 있다.
In addition, a first injection molding process (S1) for molding the first injection product (10) and a second injection molding process (S2) for molding a second injection product (20) to be coupled to the lower side of the first injection product (10). And, by implementing the combined injection process (S3) to form a double injection by combining the first injection 10 and the second injection 20 integrally in a single process, process movement is unnecessary and work loss is minimized and productivity Can be greatly improved.
