Abstract

A device for the program-controllable exchange of injection molding dies and for the continuous preconditioning of an injection molding die, prior to and during its insertion into 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 transfer of a die assembly by means of an endless roller chain with drive pins and a drive rack entraining the die assembly. Each die emplacement has a captive drive rack which carries a coupling head for flexible temperature conditioning supply lines and each die assembly has a matching coupling head with coupling valves and an identification code incorporated in a multi-conductor connection, all connections being established by the mere lowering of the die assembly onto its die emplacement.
