ABSTRACT:
A core or shell blow (shoot) machine, equipped with a quick core-box change device, makes it possible to carry out a quick core-box change in just a few minutes, thereby reducing down time. For this purpose, the core-box change device consists of a twin carrier which is swung hydraulically in a horizontal plane about a vertical axis. The care-box in the machine, after picking up the cope and the cope ejector plate, is lowered by the lift table into the carrier, after hydraulic clamps between the table and the core-box bolster have been released. The core-box change device is then rotated 180.degree., which swings the old core-box out of the machine and, simultaneously, swings the new core-box stack-up into the machine over the lift table. In the meantime, the old blow-plate is removed from the sand magazine, outside of the machine, using the blow-plate removal device. This layout also allows collection of the remaining sand from the sand magazine in a collecting pan, which is part of the blow-plate removal device, insuring a clean, trouble-free core-box change.
