Abstract
(EN)
The present invention relates to a molding device for lens production, comprising: a lower core having, on the upper surface thereof, a plurality of lens processing parts which are recessed by a predetermined depth in a shape corresponding to the curved surface of a lens to be produced; an upper core which is disposed on the upper side of the lower core and provides pressure to the lens by pressing same toward the side of the lens processing parts; a holder of which the center is formed outside the lower core and the upper core; and a stop ring which is disposed outside the holder and has a through hole having an inner diameter larger than the outer diameter of the holder to accommodate the holder, wherein, the holder has, in the central portion thereof, a core hole in which the lower core and the upper core are accommodated, wherein the core hole is formed in a shape corresponding to the lower surface of the upper core contacting the lens processing parts when pressure is applied to the upper surface of the lower core having the plurality of lens processing parts formed therein and the lens processing parts.

La présente invention concerne un dispositif de moulage pour la production de lentilles, comprenant : un moule inférieur comportant, sur sa surface supérieure, une pluralité de parties de traitement de lentille qui sont formées en creux, sur une profondeur prédéterminée et suivant une forme correspondant à la surface incurvée d'une lentille à produire; un moule supérieur qui est disposé sur le côté supérieur du moule inférieur et exerce une pression sur la lentille par pression de celui-ci vers le côté des parties de traitement de lentille; un support dont le centre est formé à l'extérieur du moule inférieur et du moule supérieur; et une bague d'arrêt qui est disposée à l'extérieur du support et comporte un trou traversant ayant un diamètre interne plus grand que le diamètre externe du support, afin de recevoir le support. Le support comporte, dans sa partie centrale, un trou central dans lequel sont logés le moule inférieur et le moule supérieur, le trou central étant formé suivant une forme correspondant à la surface inférieure du moule supérieur en contact avec les parties de traitement de lentille lorsque la pression est appliquée à la surface supérieure du moule inférieur comportant la pluralité de parties de traitement de lentille formées en son sein et les parties de traitement de lentille.
