Abstract

1,034,617. Making cores; core boxes. FORD MOTOR CO. Ltd. March 13, 1965, No. 10753/65. Heading B3F. An undercut re-entrant portion of a sandcore 1, Fig. 6 (not shown), is formed by heating the core to destroy a complementarily-shaped insert 10, Figs. 5, 6 (not shown), e.g. of expanded polystyrene, which was impaled on a spike 9 projecting from the surface of the corebox 5 before the box was filled with oil- or resin-bonded sand 7 to form the core. The heating may cure the resin binder at the same time.
