Abstract:
1. A method of dislodging a mold from a casting formed therein, comprising: moving the mold along a processing path with the casting therein; directing a recurring or intermittent pulsed wave at an exterior wall of the mold, the pulsed wave comprising at least one of a compressed air pulse, a fuel fired gas and air mix, or a mechanically generated gaseous pulse, the pulsed wave generated by a wave source; orienting the mold in a first known, indexed position relative to the wave source; orienting the mold in a second known, indexed position relative to the wave source by means of a transfer mechanism, applying mechanical force directly to the mold by means of the transfer mechanism to assist in separating sand from the casting; and dislodging the mold from the casting.
