Blow mold cooling system for glass bottle making machine, supplies cooling air to apertures when mold is located at any location between mold closed position and mold open position

摘要

The blow mold cooling system has vertical array of cooling passages in each of the mold halves. Apertures are defined in the outer surface of each of the mold halves (2), and communicate with the vertical array of cooling passages at an intermediate location between the mold top and bottom surfaces. Cooling air is supplied to a selected end of the array of cooling passages when the mold halves are at the closed position, and to the apertures when the mold is located at any location between the mold closed position and the mold open position.
