Abstract

A mold support assembly (28) includes a support (164) located within a heated chamber (22) and having a construction that reduces thermal expansion. A vertical guide (170) located externally of the heated chamber has a vertically movable connection (172) to the support (164) to permit vertical movement thereof at a horizontally fixed location. A mold support (174) for supporting a mold that provides forming of heated glass sheets is supported on the support (164) by support mounts (176) and is positioned by positioners (178,180) that provide a thermally stable center. The support (164) is constructed as a tubular support having fluid inlet (166) and a fluid outlet (168) through which a liquid coolant flows to reduce thermal expansion.
