Abstract: An apparatus and method for molding multi-material parts. The mold has a plurality of first mold cavities interspersed alternately among a plurality of second mold cavities. A first molten material is injected into the first mold cavities and solidified. Cores with the first material are moved only one mold pitch to the second mold cavities where a second molten material is injected and solidified with the first material to form the multi-material parts which are ejected from the mold when it is opened. In one embodiment, cavities and cores are arranged in a column, and dummy cores on each end of a column of cores close off the injection nozzle in an end cavity from which a core has been removed for a molding cycle. In another embodiment, cavities and cores are arranged radially, and cores are rotationally moved one mold pitch with each molding cycle.

Abstract: An apparatus and method for folding a hinged molded part in a molding machine. As a part-removal apparatus, preferably a swing arm mechanism, grips one of the lid portion or the base portion of the molded part and moves the molded part out of the mold, a deflector connected to a portion of the mold engages the other portion of the part and initiates folding of the lid portion to the base portion at the hinge. The deflector further folds the part as the mold closes. The portions of the part are pushed together and latched in one embodiment by the swing arm mechanism that grips and moves the molded part against the deflector, and in another embodiment by a closing actuator operated separately from the swing arm mechanism.
