When extracting the castings ( ) produced in a mould foundry plant, comprising an extraction station receiving the moulds ( ) with solidified castings ( ) positioned in the mould cavities at the mould-parting surface between mould parts a part of the casting ( ) to be extracted is gripped in a fixed position and orientation before opening the mould cavity containing said casting, said gripping providing a positive, fixed engagement between the gripping tool ( ) and the casting ( ), the mould cavity containing the gripped casting ( ) is opened by removing a first mould part ( ), the gripped casting ( ) is extracted from the mould cavity, and the casting ( ) is moved to a delivery position for further processing thereof. This provides a possibility of delivery of the extracted casting ( ) in a well-defined position and orientation for the further processing thereof.

Method and apparatus for extracting castings produced in a mould foundry plant

In a method of extracting castings ( ) from moulds in a mould-string plant, the downstream-most mould ( ) is gripped by a robot gripper ( ) and made to cooperate with an engagement member ( ), the latter first penetrating into the mould adjacent the casting ( ) and then pulling the latter away from the mould. By proceeding in this manner it is possible to achieve a reliable extraction using relatively simple equipment and procedures. Other types of engagement members could be suctions cups or electromagnets.
