    摘要: An exemplary molding apparatus (100) includes a first mold core (110), a second mold core (120), a lens holder (130), an elastic member (140) and a mold frame (150). The first mold core is substantially cylindrical and has a first molding surface for press molding a top surface of a lens. The second mold core is substantially cylindrical and has a second molding surface for press molding a bottom surface of the lens. The lens holder has a cavity for fitting the lens. The elastic member is a spring. The elastic member is placed between the lens holder and the second mold core. The first mold core, the second mold core, the lens holder and the elastic member are disposed in the mold frame.
