ABSTRACT:
A device for injection moulding plastic articles by the fusible-core technique includes a unit (1) for moulding fusible cores, a unit (2) for injection moulding, a unit (3) for melting and for recovering the fusible cores and a unit (4) for washing the moulded parts. The first two units are served by a mobile transfer robot (5) equipped with a rotatable arm having a ripper adapted to catch a fusible core and a gripper adapted to catch a moulded part. The two latter units are served by a stationary robot for melting (8) which interacts with the transfer robot (5). By programming the various functions performed by the robots, it is possible to carry out in parallel the moulding cycles of fusible cores and of injection moulding of the desired parts with a minimum of non-productive time and hence to obtain an automatic production with a high yield.
