Abstract

본 발명은 광학소자 성형용 금형의 광학소자 부착 방지장치에 관한 것으로, 제 3 도 내지 제 6도와 같이, 상형(11)과 하형(12) 및 이송 금형(30)으로 이루어지는 성형 캐비티에 광학유리를 넣고 가압성형하여 광학소자를 제조하는 광학소자 성형용 금형의 이송 금형(30)이 상부링(1'')과 하부링(2)으로 구성됨과 아울러 상기 상부링(1)과 하부링(2)은 내주면(1')(1''), 내주면(2')(2 )이 단차지게 형성되고, 하부링(2)의 상단부가 상부링(1)의 내주면(1'')에 끼워져 부착방지홈(3)이 형성되게 구성되어 있으며, 상기 상부링(1)와 하부링(2)은 상부링(1)의 열팽창계수가 하부링(2)의 열팽창계수 크게 되는 재질로 각각 형성된 구성으로 되어 있다. 이러한 본 발명은 광학 유리 가압성형 과정에서 가압후 압력 제거시 성형된 광학소자가 상형에 부착되어 올라감으로써 발생되는 불량을 방지할 수 있고 이에 따른 작업시간의 지연을 방지할 수 있으며, 광학소자가 상형에 부착됨을 방지하기 위하여 이형재를 도포하여야 하는 복잡한 공정이 추가되고 이형재 도포시 행하여야 하는 성형면의 초정밀 연마 공정 등을 실시하지 않게 됨으로써 작업시간의 단축, 불량율 감소 및 원가절감 등의 효과를 얻을 수 있다.The present invention relates to a device for preventing the attachment of an optical element of a mold for forming an optical element, and as shown in FIGS. 3 to 6, an optical glass is formed in a molding cavity including an upper mold 11, a lower mold 12, and a transfer mold 30. The transfer mold 30 of the mold for optical element forming, which is formed by pressing and forming an optical element, is composed of an upper ring 1 ″ and a lower ring 2, and the upper ring 1 and the lower ring 2. The inner circumferential surface 1 ', 1' ', the inner circumferential surface 2', 2 are formed stepped, and the upper end of the lower ring 2 is fitted to the inner circumferential surface 1 '' of the upper ring 1 to prevent adhesion. The groove 3 is formed, and the upper ring 1 and the lower ring 2 are each formed of a material in which the thermal expansion coefficient of the upper ring 1 is large. have. The present invention can prevent the defect caused by the optical element is attached to the upper mold when the pressure is removed after the pressure in the optical glass pressing process, thereby preventing the delay of working time, the optical element is the upper mold In order to prevent it from being adhered to, the complicated process to apply the release material is added, and the ultra-precise polishing process of the molding surface to be performed when the release material is applied is not performed, thereby reducing the work time, reducing the defective rate, and reducing the cost. have.
