ABSTRACT:
A die closing unit for injection molding machines producing articles with embedded insert parts, where the injection molding die includes several identical transfer sections which are movable between a closing station in alignment with the other die sections and a loading station in which the insert parts are placed into the transfer section of the die. A vertically movable die carrier, positioned just below the closing station, receives a transfer section of the die from a transfer station, as the transfer section is shifted horizontally into the closing station in a first embodiment, or lifted vertically into the closing station in a second embodiment. In each case, the transfer section thereby becomes independent of the transfer platen which moves the transfer sections between the transfer and loading stations.
