Abstract
A mechanism for the program-controllable exchange of injection molding dies in the die closing unit of an injection molding machine, comprising a translation table with two die emplacements which are alternatingly movable into transverse alignment with the die clamping space, for horizontal transfer of a die assembly. The transfer movement is produced by a compact roller chain drive with drive pins engaging recesses in a drive rack. The die assemblies have standardized back plates for positioning and guidance of the die assembly by means of aligned guide faces on the translation table and on a guide shelf of the die closing unit. Each die emplacement has a separate drive rack which entrains a die assembly. The drive racks are restrained against movement, when outside the transfer position.
