Abstract
A ring mold unit for shaping and tempering a glass sheet includes a shaping ring mold for bending a glass sheet heated to a temperature close to the softening point of glass, in association with upper and lower mold members, and a cooling ring mold for supporting the bent glass sheet while the glass sheet is being quenched and tempered by a cooling medium. The shaping ring mold has a thermally insulating member on its upper surface for supporting thereon, in surface-to-surface contact, the glass sheet inwardly of a peripheral edge thereof. The cooling ring mold is disposed outwardly of the shaping ring mold and having a shape complementary to the shape of the peripheral edge of the glass sheet for supporting the peripheral edge of the glass sheet. The cooling ring mold has recesses defined in the upper surface thereof, and is covered with a punched metal.
