Abstract
A molding apparatus includes a first mold, a second mold, and a body mold into which the first mold and the second mold are fittingly inserted. The body mold includes a corner section on a fitting surface with the first mold, the first mold includes an inclined surface in contact with the corner section, when the first mold is moved in a first direction and a molding material is sandwiched between the first mold and the second mold to mold a molded body, a center axis of the first mold and a center axis of the body mold are aligned by the first mold moving in a state in which the corner section and the inclined surface are in contact, and a contact section of the corner section of the body mold with the first mold viewed in the first direction is a circular or an arcuate shape.

A molding apparatus comprising:
- a first mold;
- a second mold;
- and
- a body mold into which the first mold and the second mold are fit and inserted, wherein
- the body mold includes a corner section on a fitting surface with the first mold,
- the first mold includes an inclined surface that is in contact with the corner section,
- when the first mold is moved in a first direction and a molding material is sandwiched between the first mold and the second mold to mold a molded body, a center axis of the first mold and a center axis of the body mold are aligned by the first mold moving in a state in which the corner section of the body mold and the inclined surface of the first mold are in contact, and
- a contact section of the corner section of the body mold with the first mold viewed in the first direction is provided in one of a circular shape and an arcuate shape.
A molding apparatus comprising:
- a first mold;
- a second mold;
- and
- a body mold into which the first mold and the second mold are fit and inserted,
- the molding apparatus molding an optical member by moving the first mold in a first direction and sandwiching an optical material between the first mold and the second mold fit and inserted into the body mold, wherein
- the first mold includes an inclined surface, a distance of which from a center axis decreases toward a direction closer to the body mold in the first direction, and
- the body mold includes a corner section formed by two surfaces extending respectively at different angles in the body mold with respect to the inclined surface and intersecting, the corner section facing the inclined surface in the first direction,
- the corner section being configured to come into contact with the inclined surface when the optical material is sandwiched between the first mold and the second mold.
A molding method of sandwiching and pressing a molding material between a first mold and a second mold to manufacture a molded body, the molding method comprising:
- disposing the molding material, which is heated and softened, between the first mold and the second mold fit and inserted into a cylindrical body mold;
- and
- moving the first mold in the first direction with respect to the disposed molding material to fit and insert the first mold into the body mold and sandwiching and pressing the molding material with the first mold and the second mold, wherein
- the body mold includes a corner section on a fitting surface with the first mold,
- the first mold includes an inclined surface that is in contact with the corner section,
- in the pressing, a center axis of the first mold and a center axis of the body mold are aligned by the first mold moving in a state in which the corner section of the body mold and the inclined surface of the first mold are in contact, and
- a contact section of the corner section of the body mold with the first mold viewed in the first direction is provided in one of a circular shape and an arcuate shape.
