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.
Claims6
An apparatus for separating castings from flaskless moulds of sand or similar material located at the end of a guide track which is used for guiding the intermittent advance of said flaskless moulds with its enclosed castings to a knocking-out station, comprising a number of extractors located at the vicinity of said guide track which are movable from a position of rest to a grasping position relative to the outermost casting in the row of said flaskless moulds and are thereafter retractable to the position of rest taking with them the casting mainly without adherent mould sand, wherein the extractors form a tool having at least two sets of claws equipped with vibrators and having such length and positions that on penetration into the mould sand surrounding the casting they can be caused to enclose the casting, wherein at least one of said claws is movable relative to the other for grasping contact with the casting.
