Abstract

본 발명은 프롬폼유리면과 상, 하부성형틀의 렌즈성형면 사이에 매우 얇은 가스 갭이 형성되도록 하여 렌즈성형면을 프롬폼유리에 간접 전사시킴으로써, 성형틀의 내구성과 함께 광학렌즈의 표면정도를 향상시키기 위한 것으로, 렌즈성형면이 형성되며 다공질의 분말 소결체로 이루어지는 상, 하부성형틀과, 상기 상, 하부성형틀이 상, 하부고정링에 의하여 각각 부착되며 내부에 상, 하부성형틀에 가압가스가 공급되도록 가스주입구가 형성되는 상, 하부프레스와, 상기 상, 하부프레스가 체결지지되는 상, 하부공정판으로 구성되어, 구형 또는 원판형 프롬폼유리를 다공질의 분말 소결체로 이루어진 성혈틀에 장입하는 단계와, 이후, 프리폼유리를 성형에 적정온도가 되도록 가열하는 단계와, 적정온도로 가열되면 상, 하부프레스에 의해, 상, 하성형틀을 가압하면서 가스주입구에 가압가스를 공급하여 렌즈성형면의가스 갭을 통해 프리폼유리를 간접 전사시켜 성형하는 단계와, 이후 성형된 최종렌즈를 외부로 취출하는 단계를 포함하는 광학유리의 성형장치 및 그 방법이다.According to the present invention, a very thin gas gap is formed between the surface of the formform glass and the lens forming surface of the upper and lower molds, thereby indirectly transferring the lens forming surface to the formform glass, thereby improving the surface accuracy of the optical lens together with the durability of the molding mold. In order to improve, the lens forming surface is formed, the upper and lower molding frame made of a porous powder sintered body, and the image, the lower molding frame is attached by the upper and lower fixing ring, respectively, and press the upper and lower molding frame therein The gas inlet is formed so that the gas inlet is formed, the lower press, the upper, the lower press is fastened and supported, the lower process plate, the spherical or disc-shaped pom-form glass is formed in a blood-forming frame made of a porous powder sintered body Charging step, and then heating the preform glass to a suitable temperature for molding, and when heated to a suitable temperature, by the upper and lower presses, Apparatus for forming an optical glass comprising supplying a pressurized gas to the gas inlet while pressing the indirect transfer of the preform glass through the gas gap of the lens forming surface, and then taking out the molded final lens to the outside; That's how.
