Abstract
A metal casting device employs a number of pairs of mold members which can be opened or closed with respect to each other. The mold chamber pairs cooperate, in their closed state, to form a linear mold chamber. In order to compensate for shrinkage as the metal cools, the mold member pairs are movably supported by an endless chain, with the pairs of cooperating mold members being provided with contact faces having the same angle of inclination. Each mold member pair is also equipped with supporting rollers with which the associated mold chamber section can be closed or opened, as required.
