Abstract
An apparatus for cooling tools of glass-forming machines, especially plungers and molds, in which the tool surface to be cooled is substantially covered by cover means in contact with the tool surface and in which a cooling liquid is applied to the cover means so that the liquid will evaporate and cool the cover means, as well as the tool surface in contact therewith.
Claims18
Apparatus for cooling tools of glass-forming machines by evaporation of a cooling liquid, comprising cover means substantially covering the tool surface to be cooled, said cover means having a surface in contact with said tool surface and being constructed and connected to said tool surface to vary the heat transfer between said surfaces to thus avoid film evaporation of a cooling liquid applied to that surface of said cover means which is opposite the surface in contact with said tool surface;
- and means for applying cooling liquid to said opposite surface of said cover means.
