摘要： An automated demolding apparatus for mechanically separating contact lens mold portions of a mold assembly. The mold assembly includes a first front mold portion having a central mold section with a surrounding flange, and a corresponding second back mold portion also having a central mold section with a surrounding flange, with a molded contact lens being formed between the front and back mold portions. The demolding apparatus includes restraining fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the first mold portion. A separating fixture includes separating fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the second mold portion. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the heated second mold portion relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the mold portions, while leaving the lens in the first mold portion. During demolding, the separating fixture is subjected to a substantially vertical prying motion relative to the restraining fingers to separate the second mold portion from the first mold portion.
摘要翻译：一种自动脱模装置，用于机械分离模具组件的隐形眼镜模具部分。该模具组件包括具有带周围凸缘的中央模具部分的第一前模具部分以及也具有带周围凸缘的中央模具部分的相应的第二后模具部分，在前后模具之间形成模制隐形眼镜部分。脱模装置包括限制指状件，所述指状件位于第一模具部分和第二模具部分的间隔开的凸缘的相对侧之间并且抵靠第一模具部分的凸缘。分离夹具包括分离指状物，所述分离指状物位于第一和第二模具部分的间隔开的凸缘的相对侧之间并且抵靠着第二模具部分的凸缘。在脱模之前，第二模具部分被激光束照射，由此被吸收，从而导致第二模具部分与隐形眼镜之间的显着温度梯度被脱模。温度梯度引起加热的第二模具部分的表面相对于透镜表面的不同膨胀和偏移，以减小它们之间的粘附性，以帮助模具部分分离，同时将透镜留在第一模具部分中。在脱模期间，分离夹具相对于约束指状件经受基本垂直的撬动运动以将第二模具部分与第一模具部分分离。
