A molded article transfer device (150, 250) is described herein that is associated, in use, with an injection mold (100, 200). The molded article transfer device (150, 250) includes a transfer structure (151, 251) that defines, amongst other things, a first aperture (154A) that is structured to receive a first molded article (102A) from a first mold stack (106A, 206A) of the injection mold (100). The transfer structure (151, 251) also defines a first branch channel (156A) and a first trunk channel (158A) through which the first molded article (102A) is passable. The first branch channel (156A) connects the first aperture (154A) with the first trunk channel (158A) for passing, in use, the first molded article (102A) thereto, whereafter it passes through the first trunk channel (158A) towards an exit (164A) thereof.
