Abstract
Apparatus ( ) and a method for forming heated glass sheets in a heated chamber ( ) of a housing ( ) includes an upper mold support assembly ( ) for supporting an upper mold ( ) within the heated chamber for cyclical vertical movement between upper and lower positions. A lower mold shuttle ( ) supports a lower mold ( ) for movement between an idle position horizontally spaced from the upper mold and a use position below the lower mold. The apparatus also includes a lower mold support assembly ( ) to which the lower mold is transferred from the lower mold shuttle ( ) to provide support thereof while permitting horizontal alignment with the upper mold upon each cycle of downward movement to form a heated glass sheet between the molds. The lower mold shuttle ( ) is supported by vertically movable rollers ( ) to provide the transfer between the lower mold shuttle and the lower mold support assembly ( ). A quench station ( ) includes a quench shuttle ( ) that moves a quench ring ( ) to receive the formed glass sheet from the upper mold ( ) and to then move the formed glass sheet between lower and upper quench modules ( ) of the quench station for quenching.
