Locking and holding device, principally for holding and handling of pattern plates, core masks, and the like

摘要

A locking and holding device holding and handling pattern plates, core masks and similar at molding machines in foundries. The device comprises a base plate (5) with a number of open grooves (6), which have parallel symmetry axes and are adapted to receive complementarily shaped locking studs (13), for example on a pattern plate (9). The base plate (5) is adapted to turn around a central, stationary bushing (8) projecting from the base plate, in which an upwards open recess has been made. The vertical symmetry axis of the recess is parallel to the vertical symmetry axes of the grooves in one turning position of the base plate (5). When the base plate (5) is turned away from this position, the pattern plate (9) cannot be removed from the base plate, because the wall of the recess secures the central stud (14) from the pattern plate.
