MOLDS AND APPARATUS FOR MOLDING OPTICAL COMPONENTS

1 . A mold assembly, comprising:

a first mold;

a second mold; and

a lock mounted on one of the first mold or the second mold and releasably coupled with the other of the first mold or the second mold for maintaining a position of the other of the first mold or the second mold relative to the one of the first mold or the second mold while the lock is in a closed position.

2 . The mold assembly of claim 1 , wherein:

the lock is mounted on the first mold and releasably coupled with the second mold for maintaining the position of the second mold relative to the first mold while the lock is in the closed position.

3 . The mold assembly of claim 1 , wherein:

the lock is mounted on the second mold and releasably coupled with the first mold for maintaining the position of the first mold relative to the second mold while the lock is in the closed position.

4 . The mold assembly of claim 1 , wherein:

the lock is rotatably mounted on the one of the first mold or the second mold.

5 . The mold assembly of claim 1 , wherein:

the second mold is rotatably coupled to the first mold.

6 . The mold assembly of claim 1 , further comprising:

a hinge for rotatably coupling the second mold to the first mold.

7 . The mold assembly of claim 1 , further comprising:

a handle coupled to the second mold for at least partially separating the second mold from the first mold.

8 . The mold assembly of claim 1 , further comprising:

a position indicator.

9 . An apparatus for molding, comprising:

a first platen;

a second platen; and

one or more actuators coupled with at least one of the first platen or the second platen for:

changing a distance between the first platen and the second platen; and

changing a position of a mold assembly on the second platen relative to the first platen.

10 . The apparatus of claim 9 , wherein:

the one or more actuators include a first actuator coupled with the first platen for moving the first platen relative to the second platen.

11 . The apparatus of claim 10 , wherein:

the first actuator is configured to change the distance between the first platen and the second platen.

12 . The apparatus of claim 9 , wherein:

the one or more actuators include a second actuator coupled with the second platen for moving the second platen relative to the first platen.

13 . The apparatus of claim 12 , wherein:

the second actuator is configured to rotate the second platen relative to the first platen.

14 . The apparatus of claim 9 , further comprising:

an actuator positioned to disengage a lock of the mold assembly.

15 . The apparatus of claim 9 , further comprising:

an actuator positioned to open a second mold of the mold assembly.

16 . The apparatus of claim 9 , wherein:

the mold assembly on the second platen is the mold assembly of claim 1 .

17 . The apparatus of claim 9 , wherein:

a second mold assembly is located on the second platen.

18 . A method, comprising:

maintaining the first platen of the apparatus of claim 9 in contact with a second mold of the mold assembly located at a first position while molten material is in the mold assembly;

releasing the first platen from the second mold of the mold assembly; and

subsequent to releasing the first platen from the second mold of the mold assembly, moving the mold assembly from the first position to a second position distinct from the first position.

19 . The method of claim 18 , including:

moving a second mold assembly to the first position concurrently with moving the mold assembly from the first position to the second position.

20 . The method of claim 19 , further comprising:

maintaining the first platen in contact with a second mold of the second mold assembly located at the first position; and

cooling the mold assembly at least while the first platen is in contact with the second mold of the second mold assembly.
