METHOD AND MOULD SHOOTER FOR PRODUCING MOULD PARTS, SUCH AS CASTING CORES, FOR CASTING MOULDS USED TO CAST METAL MELTS

摘要

The invention relates to a method for producing mould parts, especially casting cores, for casting moulds which are used to cast metal melts. A moulding material (F) containing an inorganic binder is loaded into a cavity (12) of a form tool (10) in a mould shooter (1) by means of filling elements such as shot nozzles (8) and shot hoods (6), said cavity defining the shape of the mould part (K) to be produced. Heat is supplied to the moulding material (F) loaded into the form tool (10) over a hardening period, in order to strengthen the moulding material (F) by dehumidifying the same. During the hardening period, at least the filling elements (6,8) of the mould shooter ( 1) which contain the moulding material (F), which are in a waiting position during said hardening period, and which are simultaneously heated by the radiant heat (W) emitted by the form tool (10), are maintained at a humidity level preventing the strengthening of the moulding material (F). In this way , mould parts for casting moulds can be reliably produced from a moulding material containing an inorganic binder, with reduced fault liability.
