METHOD OF AND MOLDING SAND CORE SHOOTER FOR MANUFACTURE OF MOLDINGS, SUCH AS CORES, FOR MOULDS AT TEEMING METAL MELT

摘要

FIELD: foundry. ^ SUBSTANCE: space of mould of sand core shooter is filled up with molding sand mixture contains inorganic binder through intake nozzles and intake head. Heat is supplied to molding sand mixture during time of solidification. Solidification of molding sand mixture takes place owing to removal of moisture. During mixture solidification process filling elements of molding sand core shooter are in waiting. Moisture content in molding mixture in filing elements is kept at level preventing its solidification. Filling elements heated by radiation heat during solidification process are periodically exposed to action of humid medium. ^ EFFECT: improved reliability of process of manufacture of moldings. ^ 18 cl, 2 dwg
