    摘要: A method of molding an optical element by pressing glass material uses a cavity composed of a pair of mold members and a side mold member. Either or both of the pair of mold members are rendered slidable along the axial direction of the optical element within the side mold member used during the pressurized molding operation, so that the pair of mold members move in close contact with the contracting glass along the axial direction in the side mold member, during the cooling subsequent to the pressurized molding due to adhesion between the contracting glass and either or both of the pair of mold members. The contraction of the glass during the cooling phase is limited by the adhesive force between the glass and the mold members when at least one of the pair of mold members traverses a gap and reaches a limit of travel; thus tension will be created in the glass.

    摘要: A forming device includes a sleeve member mountable between lower and upper mold units to hold a glass blank and having a stepped sleeve wall that defines first, second and third slot sections, and annular first and second shoulder faces. The second slot section is smaller than the third slot section and larger than the first slot section, and has top and bottom ends connected directly to the third and first slot sections. The first shoulder face extends radially at the junction of the first and second slot section to support the glass blank. A portion of the sleeve wall extends axially and upwardly from the first shoulder face to limit the glass blank from movement. The second shoulder face extends at the junction of the second and third slot sections to hold a lens formed from the glass blank.
