Installation for producing cores from flowable moulding materials in heated multi-core boxes

摘要

The installation for producing cores from flowable moulding materials in heated multi-core boxes contains a supporting frame (1) on which a transfer means (20) with core boxes (15) mounted on it, each of which has a top part (23) and a bottom part (24) and a main slide (27) and additional slides (33, 34) connected to one another kinematically by means of a connecting rod (35). The latter slides close and open central and peripheral core print holes of the core boxes (15) during interaction with their individual drives (28, 29, 31, 32). During the interaction of the main slide (27) and one of the additional slides (33) with their corresponding individual drives (28, 31), which are supported next to a press mechanism (12) on the supporting frame (1), these slides (27, 33) close the central and peripheral core print holes. During the interaction of the main slide (27) and the other additional slide (34) with their other individual drives (29, 32), which are secured on the supporting frame (1) in front of a dividing mechanism, these slides (27, 34) open the central and peripheral core print holes. <IMAGE>
