ABSTRACT:
A method for electrohydroblasting of castings in a liquid medium with a view to removing core and molding sand, according to which castings are subjected to a series of electrohydraulic shocks and at the same time set in reciprocating motion. The reciprocating frequency of the castings and the length of their stroke are sufficient to produce a flow of liquid in the internal channels of the castings and thus remove core and molding sand therefrom. The method is carried out with the aid of an apparatus which comprises a casting-reciprocating mechanism interacting with an electrode-positioning mechanism so that the movement of the castings is synchronized with that of the electrode.
