Die, platen and joining means for attaching said die to said platen

Image Number 2 for United States Patent #4552050.

A set of platens locatable as for instance on a die shoe and a slide die each contain a recess sized and shaped so as to partially receive one die of a set of dies. The platens further contain a wall which extends between the outer periphery of the platen and the recess with a hole extending through the wall and opening into the recess. The dies have a corresponding hole positioned in the dies so as to align with the holes in the walls when the dies are appropriately located in the recesses in the respective platens. A fastener has a shank with a handle having cam surfaces thereon located on one end of the shank and a flared head on the other end of the shank. A sleeve having a tapered tip fits on the shank between the cam and the tapered head with an expandable bushing then positioned between the sleeve and the head. Movement of the sleeve toward the head expands the bushing so as to lock the fastener in the aligned holes between the walls and the dies. Preferredly, the bushing would lock in the holes at the interface of the die and the wall.
