  • Publication number: 20050206019
    Abstract: A mold separation apparatus and method for breaking the cure bond between a female and male mold section of a contact lens mold unit comprises one or more pistons for striking the bottom flange wall of the female mold section with the striking force being sufficient to break the bond between the mold sections yet not so strong as to impart damage to the lens formed within the mold unit. A pick and place mechanism is included for lifting the female mold sections from the associated male mold sections and depositing the female mold sections onto a female mold pallet. Likewise, should the male mold section be used in downstream processes, the pick and place unit is operable to engage and lift the male mold sections and place them in an associated male mold pallet.
