Abstract
A releasable mold is disclosed for forming a ribbed transformer casing. The mold includes a plurality of sections first and second ones of which are endwise joined to form an annular ring. Each section has an inner portion with a concave face for forming an annular rib on a transformer casing formed by the mold with each section having an outwardly extending abutment on one opposite side portion and a recess on the other opposite side portion to receive the abutment on an adjacent section stacked thereagainst with the opposite side portions in engagement with one another to thereby accurately position the sections with respect to one another when so stacked and to thus allow a plurality of spaced annular ribs to be formed on the transformer casing. A plurality of fastening ears also extend from each section with each of the fastening ears being apertured to receive a fastening rod therein to releasably fasten the stacked and joined sections in position for forming the ribbed transformer casing.
