Abstract

A casting mold having a ventilation duct, a ventilation valve in the duct, a recess in communication with the mold cavity, a pressuresensitive membrane forming part of the wall of the recess, and actuating means responsive to flexion of the membrane, under the influence of the pressure of casting material entering the recess, to initiate closure of the valve.
