Description

플라스틱 렌즈 제조용 유리몰드{Mold for plastic lens}Glass Mold for Plastic Lens Production {Mold for plastic lens}

본 고안은 시력보정용 플라스틱 렌즈를 제조하는데 사용되는 유리몰드에 관한 것으로, 유리몰드의 표면에 경화코팅을 하여 유리몰드를 열처리하지 않아도 충분한 경도를 지닐 수 있도록 한 것이다.The present invention relates to a glass mold used to manufacture a plastic lens for vision correction, and to have a sufficient hardness without the heat treatment of the glass mold by a hard coating on the surface of the glass mold.

시력보정용 플라스틱 렌즈를 제조하기 위해서는 도 1 내지 도 3 에 도시된 바와 같이 렌즈형상을 갖는 유리몰드(1)(2)와, 상기 유리몰드(1)(2)가 양측으로 끼워지는 가스켓(3)과, 가스켓(3)에 끼워진 유리몰드(1)(2)를 고정시키기 위한 클립(7)을 구비시키게 된다.In order to manufacture a plastic lens for vision correction, as shown in FIGS. 1 to 3, a glass mold 1 and 2 having a lens shape and a gasket 3 into which the glass mold 1 and 2 are fitted to both sides. And a clip 7 for fixing the glass molds 1 and 2 fitted into the gasket 3.

유리몰드(1)(2)는 가스켓(3)내측에 형성된 단턱(4)의 양측에 끼워진 상태로 클립(7)에 의해 고정되게 된다.The glass molds 1 and 2 are fixed by the clip 7 while being fitted to both sides of the step 4 formed in the gasket 3.

그리고 주입구(5)로 플라스틱 모노머를 주입하여 배출구(6)로 공기가 배출되며 모노머가 유리몰드(1)(2)사이에 채워지게 되면 주입구(5)와 배출구(6)를 마개로 막고 18시간 정도 열중합과정을 거치도록 한다.Then, the plastic monomer is injected into the inlet (5) and the air is discharged to the outlet (6). When the monomer is filled between the glass molds (1) and (2), the inlet (5) and the outlet (6) are closed with a stopper for 18 hours. The degree of thermal polymerization process.

열중합과정이 끝나면 클립(7)을 빼내고 가스켓(3)을 절단한 후 플라스틱렌즈(10)를 유리몰드(1)(2)와 분리시켜야 한다.After the thermal polymerization process, the clip 7 is removed, the gasket 3 is cut off, and the plastic lens 10 is separated from the glass mold 1, 2.

그러나 유리몰드(1)(2)사이에 고온의 플라스틱 모노머가 채워져 18시간 열중합과정을 거치게되므로 완성된 플라스틱렌즈(10)가 유리몰드(1)(2)와 접착되어 쉽게 떨어지지 않게되며 유리몰드(1)(2)와 플라스틱렌즈(10)분리시 플라스틱렌즈(10)가 깨어지거나 유리몰드(1)(2)가 파손되어지는 문제점이 따르게 된다.However, since the high temperature plastic monomer is filled between the glass molds (1) and (2) and undergoes thermal polymerization for 18 hours, the finished plastic lens 10 is adhered to the glass molds (1) and (2) so that the glass mold does not easily fall off. When the (1) (2) and the plastic lens 10 is separated, there is a problem that the plastic lens 10 is broken or the glass mold (1) (2) is broken.

그리고 유리몰드(1)(2)는 일반유리가 아닌 강화유리를 만들어 사용하게되며 이를 위하여 유리몰드(1)(2)의 온도를 높인 후 강화액에서 400℃로 열처리과정을 거쳐야 한다.And the glass mold (1) (2) is to use the tempered glass to make a non-general glass and to this end, after the temperature of the glass mold (1) (2) to increase the heat treatment to 400 ℃ in the reinforcement liquid.

이렇게 강화처리된 유리몰드(1)(2)를 사용하더라도 매번 사용시마다 초음파세척을 해주어야 하므로 초음파에 의한 강화유리몰드(1)(2)의 손상이 많아 유리몰드(1)(2)를 조기에 교체 하여야 하는 불편이 따르게 된다.Even though the glass molds (1) and (2) treated in this way are used, ultrasonic cleaning should be performed every time they are used. Therefore, the glass molds (1) and (2) are prematurely damaged due to the high damage of the glass molds (1) and (2). It will be inconvenient to replace.

본 고안은 상기와 같은 결점을 해소시키기 위하여 플라스틱 안경렌즈 제조용 유리몰드의 표면에 경화코팅을 시킴으로써 유리몰드의 파손을 방지하는 한편 유리몰드를 경화시키는 번거러움을 없애도록 한 것이다.The present invention is to prevent the breakage of the glass mold and to eliminate the hassle of curing the glass mold by applying a curing coating on the surface of the glass mold for manufacturing a plastic spectacle lens in order to solve the above drawbacks.

이같이 플라스틱 안경렌즈 제조시 유리몰드의 일측표면에만 플라스틱 모노머가 접촉되어지므로 유리몰드를 경화시키는 번거러움 대신 유리몰드의 표면에 경화코팅을 하여 유리몰드의 경화성을 확보토록 한 것이다.In this way, since the plastic monomer is in contact with only one surface of the glass mold during the manufacture of the plastic eyeglass lens, instead of the hassle of curing the glass mold, a curing coating is applied to the surface of the glass mold to ensure the curability of the glass mold.

본 고안은 플라스틱 안경렌즈 제조용 유리몰드에 있어서, 유리몰드의 표면에 세라믹 계열의 물질로 코팅하거나, 다이아몬드화 결정구조를 가진 코팅을 실시하므로써 이루어진다.The present invention is made in the glass mold for producing a plastic spectacle lens by coating with a ceramic-based material on the surface of the glass mold, or by coating with a diamond crystal structure.

본 고안은 도 4 에 도시된 바와 같이 플라스틱 안경렌즈용 유리몰드(1)(2)의 표면에 세라믹 계열의 물질을 진공증착시킴으로써 유리몰드(1)(2)의 표면에 경화코팅층(1')(2')을 형성시킴으로써 이루어진다.The present invention is a hardened coating layer (1 ') on the surface of the glass mold (1) (2) by vacuum depositing a ceramic-based material on the surface of the glass mold (1) (2) for plastic eyeglass lenses as shown in FIG. By forming (2 ').

이때 세라믹계열의 물질을 사용하여 진공증착시키거나, 유리몰드(1)(2)의 표면에 다이아몬드화 결정구조를 가진 코팅을 실시하여도 효과는 동일하다.In this case, the effect is the same even if vacuum deposition using a ceramic-based material or coating having a diamond crystal structure on the surface of the glass mold (1) (2).

이같이 유리몰드(1)(2)의 표면에 경화코팅층(1')(2')을 형성시킬 경우 플라스틱 안경렌즈(10)제조시 플라스틱 모노머가 유리몰드(1)(2)의 경화코팅층(1')(2')에만 접촉되게되므로 유리몰드(1)(2)를 기존과 같이 경화처리시키지 않아도 된다.As such, when the curing coating layers 1 'and 2' are formed on the surfaces of the glass molds 1 and 2, the plastic monomers during the manufacture of the plastic eyeglass lens 10 are coated with the curing coating layer 1 of the glass molds 1 and 2. Since only the '2' is in contact, the glass molds 1 and 2 do not have to be cured as before.

그리고 경화코팅층(1')(2')은 유리몰드(1)(2)를 경화시킨 경우보다 강도가 높아 쉽게 흠집이 나거나 깨어질 우려가 적어진다.In addition, the curing coating layer (1 ') (2') has a higher strength than the case of curing the glass mold (1) (2) is less likely to be easily scratched or broken.

본 고안은 플라스틱 안경렌즈 제조용 유리몰드의 표면에 경도가 높게 경화코팅층을 형성시킨 것으로, 유리몰드의 열처리 과정이 불필요하여 유리몰드의 생산기간을 단축할 수 있으며 유리몰드에서 플라스틱렌즈를 분리 시킨후 초음파 세척시 경화코팅층에 의해 유리몰드의 손상을 방지하게 되므로 유리몰드의 재사용기간을 늘릴 수 있다.The present invention is to form a curing coating layer with a high hardness on the surface of the glass mold for manufacturing plastic glasses lenses, the heat treatment process of the glass mold is unnecessary, the production period of the glass mold can be shortened, and the ultrasonic glass after separating the plastic lens from the glass mold Since the glass coating prevents the glass mold from being damaged by the curing coating layer, the reuse period of the glass mold may be increased.
