1. A stack mold carrier for supporting a center mold section of an injection mold including a platen assembly of an injection molding machine, the stack mold carrier comprising:
a carrier base for releasably coupling with the center mold section, wherein the carrier base is configured for displacement, relative to the platen assembly, along a machine axis;
a linkage assembly pivotally connected to the carrier base and configured for pivotally connecting to a first platen and to a second platen of the platen assembly;
a first restraint system for releasably retaining the linkage assembly in a fixed position relative to the carrier base, the first restraint system defining:
a first condition, wherein the linkage assembly is fixed relative to the carrier base such that pivotal movement of the linkage assembly relative to the carrier base is prevented; and
a second condition wherein the linkage assembly is disposed for pivotal movement relative to the carrier base and is operably coupled to the first and second platens and disposed for pivotal movement relative to the first and second platens; and
a lift support body for releasably coupling with a lifting mechanism, the lift support body supporting the stack mold carrier when subjected to a lifting force via the lifting mechanism;
wherein:
while the first restraint system is disposed in the first condition, the stack mold carrier is disposed for installation on the platen assembly as an assembled unit.
