Abstract

A method and apparatus for improving kinematic characteristics and for obtaining greater variability with respect to the use possibilities when handling core parts for providing a read-to-cast core stack, wherein, following a removal from a core shooting machine, the core parts are assembled at a stacker to form a core stack, introduced into a dipping bath and subsequently supplied in a correct position to a casting machine. The stacker, successively stacks in each case an upper core or an already assembled core part stack, with the upper core part or the already assembled core part stack being exclusively linearly raised and, in each case, a lower core part is held in a floating manner by an air cushion, whereas the raised core part or core part stack is lowered onto the lower core part for assembly.
