  • Patent number: 12138835
    Abstract: A method for creating optical articles includes moving first and second mold portions relative to one another. This disclosure includes injection molds for reducing cycle times and related methods. Some molds include first and second mold portions movable relative to one another from open to closed positions in which each recess of the first mold portion cooperates with a respective recess of the second mold portion to define a chamber. Each chambers includes a first cooling body coupled to the first mold portion, a second cooling body coupled to the second mold portion, and first and second inserts removably coupled, respectively, to the first and second cooling bodies. The inserts cooperate to define a mold cavity within the chamber configured to receive a thermoplastic material. Each of the cooling bodies has an inlet, an outlet, and a fluid cavity in fluid communication with the inlet and the outlet.
