이와 같이 구성된 본 발명의 실시예에 따른 다색 간이 렌즈의 제조과정을 상세히 살펴보면 다음과 같다.Looking at the manufacturing process of the multi-color simple lens according to an embodiment of the present invention configured as described above are as follows.
우선, 실리콘을 이용하여 렌즈의 표면측 주형과 어안측 주형을 각각 형성하게 된다. 이때, 표면측 주형과 어안측 주형은 서로 형합되었을 때에는 렌즈의 외형과 동일한 캐비티를 형성하게 된다(P101).First, silicon is used to form the surface-side mold and the fish-eye mold, respectively. At this time, when the surface-side mold and the fish-eye mold are matched with each other, they form the same cavity as the outer shape of the lens (P101).
그리고, 서로 분리된 상태의 실리콘 주형을 소정 시간동안 각각 가온시킨 다음, 캐비티를 형성하는 표면에 이형제를 도포시키게 된다(P102)(P103). 그 후, 실리콘 주형을 서로 형합하여 중심부에 렌즈의 표면측과 어안측을 형성하는 캐비티를 형성하게 된다(P104). 이때, 실리콘 주형은 테이핑에 의해 서로 고정될 수 있도록 한다.Then, the silicon molds separated from each other are warmed up for a predetermined time, and then a release agent is applied to the surface forming the cavity (P102) (P103). Thereafter, the silicon molds are joined to each other to form a cavity in the central portion which forms the surface side and the fisheye side of the lens (P104). At this time, the silicon molds can be fixed to each other by taping.
그 다음, 투명한 단색 렌즈의 재료가 되는 수지를 용융시킨 상태에서 진공을 이용하여 그 용융수지의 기포를 제거시킨 후, 그 탈포된 용융수지를 형합된 실리콘 주형의 캐비티에 주입시켜 그 주입된 용융수지가 경화되도록 소정시간 동안 냉각시키게 된다(P105)(P106)(P107).Then, bubbles of the molten resin are removed using a vacuum while melting the resin, which is a material of the transparent monochromatic lens, and then the degassed molten resin is injected into the cavity of the molded silicon mold, thereby injecting the molten resin. Is cooled for a predetermined time to harden (P105) (P106) (P107).
이렇게 하여 용융수지의 경화가 완료되면 실리콘 주형을 서로 분리한 다음, 그 경화로 인해 형성된 단색의 렌즈를 실리콘 주형으로부터 탈형하고, 그 렌즈에 묻은 이형제를 세척을 통해 제거하게 된다(P108)(P109).In this way, when the curing of the molten resin is completed, the silicon molds are separated from each other, and then the monochromatic lens formed by the curing is demolded from the silicone mold, and the release agent on the lens is removed by washing (P108) (P109). .
그 후, 이형제가 제거된 단색 렌즈를 수가공을 통해 보수작업한 다음, 다듬질가공 및 연마가공을 통해 단색 렌즈의 가공을 마무리하게 되며, 그 단색의 렌즈 표면에 소정의 색체를 페인팅하게 되면, 다색의 간이 렌즈제조가 완료된다(P110)(P111)(P112).After that, the monochromatic lens from which the release agent has been removed is repaired by hand, and then the monochromatic lens is finished through finishing and polishing, and when a predetermined color is painted on the monochromatic lens surface, The manufacturing of the simple lens is completed (P110) (P111) (P112).
이상에서 살펴본 바와 같이, 본 발명은 다색사출공법이나 다색주형공법을 이용하지 않고 간이 실리콘 주형으로 성형된 실리콘 주형품의 렌즈 표면에 다색 페인팅 조색작업으로 간이 다색렌즈를 간편하게 제조할 수 있게 된다.As described above, the present invention enables a simple multicolor lens to be easily manufactured by multicolor painting tinting on the surface of a lens of a silicon mold molded into a simple silicon mold without using the multicolor injection method or the multicolor molding method.
따라서, 본 발명은 정규공법인 다색사출공법에서 제조되는 양산 다색렌즈와 거의 유사한 미감을 얻을 수 있게 되면서도 짧은 시간내에 간편하게 제조할 수 있게 되므로, 모델 자동차의 개발시간과 개발비용을 절감할 수 있게 된다.Therefore, the present invention can be easily manufactured in a short time while obtaining a similar aesthetics to the mass-produced multicolor lens manufactured by the multicolor injection method, which is a regular method, it is possible to reduce the development time and development cost of the model car.
본 발명은 특정의 실시예와 관련하여 도시 및 설명하였지만, 첨부 특허청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 당업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described with respect to particular embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the appended claims. Anyone can easily know.
