【Abstract】 It is difficult to meet the requirement of molding high precision optics plastic lens because the experience play an important role in the traditional plastic mold design and molding process. The dynamic process of injection and holding for optical plastic lenses is simulated by means of CAD/CAE technology. The effect of pressure, temperature and cycle on the surface figure of the lenses during injection and holding process is discussed.更多还原
