ABSTRACT:
An apparatus and method for holding a mold assembly and molding an optical lens using the same. In one aspect, the present invention provides an apparatus for holding a mold assembly, wherein the mold assembly includes a front mold, a back mold and a strip wrapping around the edges of the front mold and back mold to form a sleeve. In one embodiment, the apparatus includes a first portion and a second portion. The first portion has a top part, a bottom part, and a middle part connecting the top part and the bottom part, the middle part including a base and a holder coupled to the base. The second portion has a top part, a bottom part, and a middle part connecting the top part and the bottom part, the middle part including a base and a holder coupled to the base. The first portion and the second portion are pivotally coupled together at the bottom parts so that the top part of the first portion and the top part of the second portion can be closed to define a housing for receiving the mold assembly therein, wherein the top part of the first portion and the top part of the second portion can also be opened for receiving the mold assembly in the housing.
