Patent ID: 7985064

Claim:
A lens mold, comprising: a first pressing portion defining an inlet to receive material to make a plurality of lenses; a second pressing portion; a shaping portion disposed between the first pressing portion and the second pressing portion, the shaping portion comprising an upper slide and a lower slide connected to the second pressing portion, the upper and lower slides configured for sliding along each other; a plurality of mold cavities in fluidic communication with a flow path, the flow path having a plurality of branch flow paths extending to the mold cavities, and the flow path being in fluidic communication with the inlet such that the lens material flows from the inlet along the flow path and the branch flow paths to the mold cavities, the mold cavities contoured to define at least one surface of each of the lenses, wherein contours of the mold cavities, the flow path and the branch flow paths are defined when the upper slide and lower slide close; and a recess defined on a surface of the second pressing portion that is adjacent to the shaping portion, the recess in fluidic communication with the flow path when the upper slide and the lower slide close so as to receive a portion of the lens material; wherein the first pressing portion comprises a first base and a first pad disposed on a surface of the first base that is in proximity to the shaping portion, and the second pressing portion includes a second base and a second pad provided on a surface of the second base that is adjacent to the shaping portion, the upper slide and the lower slide being connected to the second pad of the second pressing portion.
