ABSTRACT:
A basin former on a squeeze plate coacts with a sprue former on a pattern plate to form a pouring basin and a sprue in a sand mold. Sand which enters the basin former during formation of the pouring basin is ejected upwardly therefrom by pressurized air which is introduced into the basin former through an opening in the side of a plastic liner located in the basin former. The squeeze plate is modular in nature in that the basin former may be attached to the squeeze plate at any selected one of several locations without need of disconnecting and re-connecting the source of pressurized air when the position of the basin former is changed.
