ABSTRACT:
The invention concerns the technical problem of providing a simple and reliable apparatus for separating castings from moulds of sand or similar material at the end of a guiding track, on which the moulds with the enclosed castings are advanced step by step towards a knocking-out station. With a view hereto the apparatus comprises a number of possibly interchangeable claws equipped with vibrators which, when moved into the row of moulds, can penetrate the mould sand and be caused to enclose and pinch the outermost casting, whereafter the claws are shifted back to the initial position in which the pair of tongs formed by the claws can open in order to deliver the casting for further treatment. The claws can be specially formed so as to retain possible core sand in the castings.
