CONFORMING COOLING METHOD AND MOLD

摘要

A method for forming a conformal fluid circulating passage in a mold includes providing a mold including a molding surface with an open passage thereon, the depth of the passage substantially conforming to the contour of the molding surface, the passage defining a plurality of open fluid channels including a first channel, a second channel downstream of the first channel and a third channel downstream of the second channel; and wherein each fluid channel defines a centerline that extends from the bottom of the open passage to the molding surface and a channel longitudinal centerline, and the method includes maintaining a common distance between the longitudinal centerlines and the molding surface and between the centerlines of adjacent channels.

主权项

1. A part producing mold having a cooling fluid passage defined therein, comprising:
a channel defined in a mold surface of the mold by spaced apart lateral walls depending from the mold surface of the mold toward a closed bottom of the channel; a nonconsumable steel weld support received in the channel and positioned adjacent the closed bottom; and a bridge welded across the channel onto and above the weld support and directly to the lateral walls for closing the channel and defining the fluid passage.
