ABSTRACT:
A mold for casting bullets comprising a plurality of adjacent mold blocks having paired opposing cavity portions within opposing lateral surfaces of adjacent blocks for forming casting cavities when the mold is closed and the opposing lateral surfaces are in contact has interlocking means at least partially integral of the adjacent blocks for providing a sliding surface contact for the block during pivotal movement thereof and for limiting relative movement between the blocks to arcuate separation and closure of the adjacent blocks in a plane which is perpendicular to the opposing lateral surfaces of the blocks. Means integral of the opposing lateral surfaces of adjacent blocks provide at least one pivot center of arcuate separation and closure between the adjacent blocks and means are provided for retaining at least a portion of the opposing lateral surfaces of adjacent blocks in contact during the arcuate separation and closure of the blocks.
