Abstract
In a method of extracting castings (1, 2, 3) from moulds in a mould-string plant, the downstream-most mould (1) is gripped by a robot gripper (9) and made to cooperate with an engagement member (14), the latter first penetrating into the mould adjacent the casting (4) 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.
Claims18
Method of extracting castings from casting cavities in moulds being advanced in a string of moulds, in which the casting cavities are defined by surfaces in each mould and oppositely facing surfaces in preceding and succeeding moulds, respectively, characterized by the following steps a-d inclusive:
- a) the downstream-most mould is gripped by a robot gripper engaging at least its lateral faces extending in the direction of advancement of said string of moulds,
- b) said downstream-most mould is moved using said robot to an extraction station comprising at least one engagement member,
- c) said engagement member or members is/are brought into engagement with said casting, all by suitable relative movement of said downstream-most mould and said engagement member or members, and
- d) said engagement member or members and said downstream-most mould are moved relative to each other in a manner to disengage said casting from said mould.
