유리판의 두께는 0.2 ~ 3mm이다.The thickness of the glass plate is 0.2 to 3 mm.

본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention is described in detail by the accompanying drawings as follows.

도 1은 본발명 비구면유리를 제조하는 방법을 나타낸 블록도, 도 2는 본발명 하부금형이 다른 비구면유리를 제조하는 방법을 나타낸 블록도이다.1 is a block diagram showing a method for producing the aspherical glass of the present invention, Figure 2 is a block diagram showing a method for producing aspherical glass different from the lower mold of the present invention.

본발명은 비구면유리형상으로 홈이 형성되는 하부금형위에 유리판을 안치한다. 유리판의 두께는 0.2 ~ 3mm이고, 상기 금형은 금속재질이며, 상기 홈의 깊이는 0.5 ~ 60mm, 홈의 크기는 가로 40 ~ 400mm, 세로 35 ~ 350mm이다. 이때 후공정인 진공시 유리판이 상부로 움직이지 않게 고정구를 상기 유리판 상면 테두리를 따라서 설치하고 고정구의 하부는 하부금형에 고정한다.According to the present invention, a glass plate is placed on a lower mold in which grooves are formed in an aspherical glass shape. The thickness of the glass plate is 0.2 ~ 3mm, the mold is a metal material, the groove depth is 0.5 ~ 60mm, the groove size is 40 ~ 400mm horizontal, 35 ~ 350mm vertical. At this time, during the vacuum process, the glass plate is installed along the upper edge of the glass plate so that the glass plate does not move upward, and the lower part of the fixture is fixed to the lower mold.

이후 상기 하부금형과 유리판을 챔버 내부에 장입한다. Thereafter, the lower mold and the glass plate are charged into the chamber.

이후 챔버 내부를 진공으로 만든다.The chamber interior is then evacuated.

진공압력은 100Torr ~ 10-3Torr이다.Vacuum pressure ranges from 100 Torr to 10 -3 Torr.

이후 챔버 내부를 가열한다. 상기 챔버는 전기히터에 의해 가열하되, 가열온도는 350 ~ 800℃로 가열한다.The chamber interior is then heated. The chamber is heated by an electric heater, the heating temperature is heated to 350 ~ 800 ℃.

이후 챔버 내부에 불활성 가스를 불어넣고 압력을 가하게 된다. 챔버 내부에 아르곤 같은 불활성 가스를 불어넣고 압력을 가하는 시간은 25 ~ 35분이며, 적정시간은 30분이며, 압력은 0.5 ~ 3kg/㎠이다.Thereafter, an inert gas is blown into the chamber and pressure is applied. Injecting an inert gas such as argon into the chamber and applying pressure was 25 to 35 minutes, an appropriate time was 30 minutes, and a pressure was 0.5 to 3 kg / cm 2.

상기 챔버 내부에 불활성 가스는 천천히 불어넣되 불어넣기 시작하는 시간은 유리판이 고온에 의해 물렁해져 하부금형 홈에 주저앉기 시작되는 시간으로서 가열후 8 ~ 15분 정도이다.The inert gas is slowly blown into the chamber, but the time for starting the blowing is about 8 to 15 minutes after heating as the glass plate becomes soft due to the high temperature and starts to sit in the lower mold groove.

한편, 본 발명의 다른 실시 예로서, 상기 하부금형은 표면에 상부로 볼록한 비구면유리형상인 돌출부(120)가 형성된다.On the other hand, as another embodiment of the present invention, the lower mold is formed with a protrusion 120 having an aspherical glass shape convex upward on the surface.

그리고 상기 돌출부가 형성된 하부금형 위에 유리판을 안치하고, 유리판이 움직이지 않게 고정구를 상기 유리판 상면 테두리를 따라서 설치하며, 고정구의 하부는 하부금형에 고정한다.Then, the glass plate is placed on the lower mold on which the protrusion is formed, and a fixture is installed along the upper edge of the glass plate so that the glass plate does not move, and the lower part of the fixture is fixed to the lower mold.

이후 하부금형과 유리판을 챔버내부에 장입한다.After that, the lower mold and the glass plate are charged into the chamber.

이후 챔버 내부를 진공으로 만든다.The chamber interior is then evacuated.

이후 챔버 내부를 가열한다.The chamber interior is then heated.

이후 챔버 내부에 불활성 가스를 불어넣고 압력을 가하게 된다.Thereafter, an inert gas is blown into the chamber and pressure is applied.

이에, 상부로 볼록한 비구면 유리를 제조하게 되는 것이다.Thus, it is to produce an aspherical glass convex upward.

따라서 본발명은 작업이 간단하며, 하부금형만을 사용함으로 비구면 유리 제품에 기포나 스크래치 등의 결함이 없고, 금형이 산화되지 않고 형상 및 치수가 정확하다는 현저한 효과가 있다.Therefore, the present invention is simple in operation, and by using only the lower mold, there is a remarkable effect that the aspherical glass products are free from defects such as bubbles or scratches, and the mold is not oxidized and the shape and dimensions are accurate.
