Abstract
A one-piece water jacket core for an internal combustion engine is formed by providing a first core box portion and a second core box portion adapted for assembly and formation of the one-piece water jacket core. The first core box portion includes a first cavity adapted to form a lower portion of the one-piece water jacket core and the second core box portion includes a second cavity adapted to form an upper portion of the one-piece water jacket core. A plurality of movable members are pivotally carried adjacent to, and preferably by, one of the core box portions. Each of the pivotal movable members includes a portion adapted to form a water jacket port and to be pivoted, after assembly of the first and second core box portions, to a position forming one of the water jacket ports in the one-piece water jacket core. The invention is particularly adapted for the formation of one-piece water jacket cores with a cold-cure process.
