A method of loading a moldset having a core plate and a cavity plate into an injection molding machine. The method comprises the steps of latching a cavity plate to a core plate using a removable latch, guiding the core plate into an open mold along a face in the mold while maintaining separation between the face and the core plate and maintaining the cavity plate spaced from hot runner nozzles in a hot runner in the mold, closing the mold to engage the cavity plate with the hot runner nozzles, securing the cavity plate to the hot runner, removing the latch between the cavity plate and the core plate, and opening the mold. The face may be a face of a movable platen or a back surface of a hot runner.

Cette invention concerne un procédé servant à réaliser le chargement d'une carcasse de moule, comprenant une plaque à noyau et une plaque de matrice, dans une machine de moulage par injection. Ce procédé consiste: à verrouiller une plaque de matrice contre une plaque à noyau en utilisant un verrou déverrouillable; à guider la plaque à noyau dans un moule ouvert le long d'une face du moule, tout en maintenant la séparation entre cette face et la plaque à noyau et tout en maintenant la plaque de matrice distante des buses d'un canal chauffant du moule; à fermer le moule la plaque de matrice coopère avec les buses du canal chauffant; assujettir la plaque de matrice contre le canal chauffant; à retirer le verrou entre la plaque de matrice et la plaque à noyau; et à ouvrir le moule. La face mentionnée peut être une face à plateau amovible ou une surface arrière d'un canal chauffant.
