Description

렌즈의 제조방법Manufacturing method of the lens

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 블록렌즈 제조용 금형틀 및 볼록렌즈의 분해사시도,1 is an exploded perspective view of a mold and a convex lens for manufacturing a block lens of the present invention;

제3도는 본 발명을 실시하는 용융된 합성수지의 사출공정을 나타낸 단면도,3 is a cross-sectional view showing the injection process of the molten synthetic resin according to the present invention,

제5도는 금형을 낱개로 분해한 다음 불필요한 부분을 절단하는 공정을 나타낸 사시도.5 is a perspective view showing a process of disassembling a mold individually and then cutting unnecessary portions.

서로 대향하는 한벌의 금형틀이 접합하는 접합면에 성형하려는 볼록렌즈의 양쪽 블록면 형상에 대응한 케비티를 각설하고, 상기 한벌의 금형틀을 각 금형틀간에 각설되어 있는 케비티 중심부에 성형하려는 볼록렌즈 보다 약간 적게 형성한 합성수지제 볼록렌즈 코아를 유지해서 접합함과 동시에 볼록렌즈 코아 양쪽의 케비티 안쪽의 볼록렌즈 코아와 같은 원료인 용융된 합성수지를 사출하여 볼록렌즈를 일체로 성형하는 렌즈의 제조방법.The cavity corresponding to the shape of both block surfaces of the convex lens to be molded is laid out on the joint surface joined by a pair of molds facing each other, and the mold is molded in the center of the cavity placed between the molds. The lens is formed by integrally molding the convex lens by injecting the synthetic resin, which is a raw material such as the convex lens core inside the cavity on both sides of the convex lens core, while maintaining and bonding the convex lens core made of synthetic resin slightly smaller than the convex lens. Manufacturing method. 서로 대향하는 한벌의 금형틀이 접합하는 접합면에, 성형하려는 오목렌즈의 양쪽 오목면 형상에 대응한 케비티를 각설하고, 상기 한벌의 금형틀을, 각 금형틀에 각설되어 있는 케비티 내부에 성형하려는 오목렌즈 양쪽면의 표층 형상에 분할 성형한 합성수지제의 오목형 표층렌즈를 유지해서 접합함과 동시에, 상기 양표층 렌즈의 내부공간에 그 표층렌즈와 같은 원료인 용융된 합성수지를 사출해서 오목렌즈를 일체로 성형하는 렌즈의 제조방법.A cavity corresponding to the shape of both concave surfaces of the concave lens to be molded is laid out at the joint surface to which a pair of mold dies join each other, and the pair of mold dies is placed inside the cavity laid in each mold die. While retaining and bonding the concave surface lens made of synthetic resin separately formed into the surface layer shape on both surfaces of the concave lens to be molded, the molten synthetic resin, which is the same material as the surface layer lens, is injected into the inner space of the two surface layer lens and concave. A method of manufacturing a lens that integrally molds a lens. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
