A latching device (20) for a mold assembly (10) uses a cam action to hold the "A" side plate against the hot runner system/nozzle plate (18) during operation. Preferably, a latch (20) is provided on each side of the mold to effectively hold the "A" side plate against the nozzle plate (18) during the high pressure injection of plastic melt. For purposes of a mold insert change, each latch (20) is rotated to release the "A" side plate from the nozzle plate (18), and hold the "A" side plate against the "B" side plate. This enables the "A" (12) and "B" (14) portions of the mold assembly to be moved away from the nozzle plate (18), thereby avoiding interference of the hot runner nozzles and "A" side insert and enabling quick mold insert change.

L'invention concerne un dispositif de verrouillage (20) pour un ensemble moule à injection (10) utilisant l'action d'une came pour maintenir la plaque côté "A" contre le système à canaux chauffés (plaque de buses) (18) pendant le fonctionnement. De préférence, un verrou (20) disposé sur chaque côté du moule permet de maintenir efficacement la plaque de buses du plaque côté "A" contre la plaque de buses (18) pendant l'injection sous haute pression du plastique fondu. Afin de changer les éléments du moule, chaque verrou (20) est tourné de façon à libérer la plaque côté "A" de la plaque de buses (18) et de maintenir la plaque côté "A" contre la plaque côté "B". Les parties "A" (12) et "B" (14) de l'ensemble moule peuvent ainsi être éloignées de la plaque de buses (18), ce qui permet d'éviter tout interférence des buses à canaux chauffés et l'élément côté "A" et de changer rapidement les éléments de moulage.
