A structure for releasably securing a plurality of mold inserts to a mold plate attached to a power press machine is disclosed. The mold plate has a plurality of apertures formed therethrough. Within each aperture, a plurality of inwardly extending spaced apart protrusions are formed. The mold inserts include end portions having a plurality of tabs formed thereon. A mold insert is inserted within an aperture by aligning the tabs with the spaces between the protrusions and moving the mold insert axially therein. Then, by rotating the mold insert relative to the mold plate, the tabs are moved over the protrusions. As a result, the mold insert is retained within the aperture. Locking bars prevent rotation of the mold inserts at undesired times to prevent them from being removed from the mold plate. A locking mechanism may be used to secure the locking bars, and therefore the mold inserts, in their locked positions during use.
