Abstract
A mold stack for forming 3D glass-based articles includes a plenum and a cooling structure integrated with the plenum. The mold stack includes a mold with a flange that can be used to mount the mold on the plenum. The mold stack includes features to reduce mold warp without significantly increasing thermal mass.
Claims21
A mold stack for forming 3D glass-based articles, comprising:
- a mold having a flange at a periphery thereof;
- and
- a vacuum plenum having a plenum base joined to a plenum enclosure wall, the mold mounted on the vacuum plenum such that the mold, the plenum base, and the plenum enclosure wall define a plenum chamber therein, and the plenum chamber comprising:
- a cooling chamber arranged between a diffuser plate, a cooling structure wall on which the diffuser plate is mounted, and the plenum base, wherein the cooling structure wall is joined to the plenum base such that a portion of the plenum base forms a cooling structure base, wherein the cooling chamber, the diffuser plate, the cooling structure wall, and the cooling structure base form a cooling structure within the vacuum plenum;
- and
- a process chamber arranged between the mold, the cooling structure wall, the plenum base, and the plenum enclosure wall;
- and
- an inlet hole and an exit hole formed in the cooling structure base, the inlet hole and exit hole being in communication with the cooling chamber;
- and
- wherein the flange of the mold is removably attached to a top surface of the plenum enclosure wall and the vacuum plenum is made in one piece.
