Title: METHOD AND APPARATUS FOR HOLDING A MOLD ASSEMBLY AND MOLDING AN OPTICAL LENS USING THE SAME
Abstract:
An apparatus and method for holding a mold assembly (11) and molding an optical lens using the same. In one aspect, the present invention provides an apparatus for holding a mold assembly (11), wherein the mold assembly (11) includes a front mold (12), a back mold (14) and a strip (20) wrapping around the edges (13, 15) of the front mold (12) and back mold (14), respectively, to form a sleeve. In one embodiment, the apparatus includes a first portion (102) and a second portion (152). The first portion (102) has a top part (104), a bottom part (108) and a middle part (106) connecting the top part (104) and the bottom part (108), the middle part (106) including a base (116) and a holder (118) coupled to the base (116). The second portion (152) has a top part (154), a bottom part (158), and a middle part (156) connecting the top part (154) and the bottom part (158), the middle part (156) including a base (166) and a holder (168) coupled to the base (166). The first portion (102) and the second portion (152) are pivotally coupled together at the bottom parts (108, 158) so that the top part (104) of the first portion (102) and the top part (154) of the second portion (152) can be closed to define a housing (120) for receiving the mold assembly (11) therein, wherein the top part (104) of the first portion (102) and the top part (154) of the second portion (152) can also be opened for receiving the mold assembly (11) in the housing (120).
