Abstract
A mold cooling system for an I.S. machine wherein cooling air is supplied to vertical cooling holes defined in the molds either at their ends or midway along their length.
Claims13
An I.S. glass bottle making machine comprising
- a blow station including a blow mold having a pair of opposed mold halves each having an engagement surface, an outer surface, and top and bottom surfaces,
- said mold halves moveable in a machine cycle between a closed position, in which the engagement surfaces engage to provide a mold cavity in which a parison can be blown into a bottle, and an open position,
- a vertical array of cooling passages in each of said mold halves, said cooling passages having a top end at the top surface of the mold and a bottom end at the bottom surface of the mold,
- aperture means defined in the outer surface of each of said mold halves, said aperture means communicating with said vertical array of cooling passages at an intermediate location between said top end and bottom end of the cooling passages,
- means for supplying cooling air to a selected end of said array of cooling passages when said mold halves are at the closed position, and
- means for supplying cooling air to said aperture means when the mold is located at any location between the mold closed position and the mold open position.

A system for cooling a blow mold in an I.S. glass bottle making machine, the blow mold including two mold halves and the bottle making machine including a mechanism for manipulating the blow mold, the system comprising:
- a vertical array of cooling passages defined in each mold half, the cooling passages having a top end at a top surface of each mold half and a bottom end at a bottom surface of each mold half;
- each mold half defines an aperture, with the aperture in fluid communication with at least one of the vertical cooling passages at an intermediate location between the top end and bottom end of the cooling passages;
- an air chamber configured to couple with the aperture and selectively provide air to the cooling passages;
- and
- an air supply source coupled to the air chamber.
