Patent attributes
Alignment bars are mounted to a core or cavity insert block and a portion of one end of the alignment bar projects above the plane of a molding face surface and engages with a corresponding respective mating alignment channel in the other of the core or cavity insert block when the blocks are moved into a closed operative position. A portion of the other end of the alignment bar projects below the plane of a mold base plate facing surface defining keys for insertion into pockets formed in the mold base plate of a mold base for precise fixed positioning of the insert block on the mold base plate. The other insert block is carried by a co-operating mold base and the position of the insert block is moved into alignment with the insert block mounted on the other mold base.
