Abstract

1325215 Extracting castings COMBUSTION ENG Inc 31 Aug 1971 [8 Sept 1970] 40546/71 Heading B3F Apparatus for breaking up sand moulds to free the castings therefrom comprises a frame having an opening for receiving the moulds, mould breaking tools 34 carried by said frame on opposite sides thereof, and means 32 for moving the tools into and out of said opening. The tools 34 are cruciform in cross-section and pass through slots (19) in an inner frame (20) defining said opening. A plurality of tools are mounted on plates 26 which are moved towards and away from the inner frame by hydraulic cylinders 32. In an embodiment, Fig. 8 (not shown), the device is movable to enable it to be accurately located with respect to the mould at the end of the conveyer 10. A sensing switch (125) engages with notches (115) moulded into the surfaces of the moulds for this purpose.
