Mold for optical component

Abstract

A mold for an optical component is provided which includes a first mold and a second mold which mold the optical component, a cylindrical body whose rotational symmetry axis is identical with a second symmetry axis about which a second mold is rotationally symmetric, a trunk mold whose rotational symmetry axis is identical with a first symmetry axis about which a first mold is rotationally symmetric, a supporting means which supports the first mold in such a way that the first mold moves relatively to the trunk mold in parallel with the first symmetry axis, and a second tapered surface and a first tapered surface which contacts the second tapered surface, which connect the cylindrical body with the trunk mold in such a way that the second symmetry axis is identical with the first symmetry axis.

Claims

1. A mold for an optical component comprising: a first mold and a second mold which mold the optical component;a trunk mold which centers the first mold and the second mold coaxially;a supporting means which supports the first mold and the trunk mold in such a way that the first mold and the trunk mold move against each other; anda holding means which holds the first mold, the trunk mold, and the supporting means in such a way that the first mold, the trunk mold, and the supporting means are not separated from one other.

2. The mold for the optical component as claimed in claim 1, wherein the holding means comprises a linking means which links the first mold with the trunk mold and arbitrarily expands and contracts.

3. The mold for the optical component as claimed in claim 1, wherein the trunk mold causes a first tapered surface on a side of the trunk mold to contact a second tapered surface on a side of the second mold to center the first mold and the second mold coaxially.

4. The mold for the optical component as claimed in claim 3, comprising a centering means which centers the second mold and the second tapered surface coaxially.

5. The mold for the optical component as claimed in claim 1, wherein the trunk mold centers the first mold and the second mold coaxially by means of an outside attachment which circumscribes outer peripheral surfaces of the trunk mold and the second mold.

6. The mold for the optical component as claimed in claim 2, wherein the trunk mold causes a first tapered surface on a side of the trunk mold to contact a second tapered surface on a side of the second mold to center the first mold and the second mold coaxially.

7. The mold for the optical component as claimed in claim 6, comprising a centering means which centers the second mold and the second tapered surface coaxially.

8. The mold for the optical component as claimed in claim 2, wherein the trunk mold centers the first mold and the second mold coaxially by means of an outside attachment which circumscribes outer peripheral surfaces of the trunk mold and the second mold.
