Abstract
An optical element molding mold set includes a first mold and a second mold that are opposite to each other, and a third mold that is located on an outer periphery of a cavity between the first mold and the second mold, and an inner peripheral surface of the third mold has different friction coefficients between one side and another side in an opposite direction of the first mold and the second mold.
Claims14
An optical element molding mold set comprising:
- a first mold and a second mold that are opposite to each other;
- and
- a third mold that is located on an outer periphery of a cavity between the first mold and the second mold, wherein
- an inner peripheral surface of the third mold has different friction coefficients between one side and another side in an opposite direction of the first mold and the second mold.

An optical element manufacturing method comprising:
- heating, pressing, and cooling down a molding material by using an optical element molding mold set, the optical element molding mold set including a first mold and a second mold opposite to each other so as to sandwich the molding material, and a third mold that is located on an outer periphery of a cavity between the first mold and the second mold;
- and
- molding an outer peripheral surface of an optical element by using the third mold that has different friction coefficients between one side and another side in an opposite direction of the first mold and the second mold such that speeds are adjusted at which the molding material that has been pressurized in the cavity flows toward one end and another end of an outer periphery of the cavity in the opposite direction.
