CA 2428738

A valve gate is provided for an injection molding manifold having at least one drop defining at least one channel for transporting a flow of plasticized melt therethrough. The valve gate has a pin mounted in the manifold to extend across the channel in a sliding relation. The pin has a transversely extending aperture that aligns with the channel opening the flow. Reciprocating movement of the pin in a direction transverse to the flow of the plasticized melt opens and closes flow thereof.

L'invention concerne un robinet de collecteur de moulage par injection ayant au moins une ouverture définissant au moins un canal pour le transport d'un flux de matière plastique fondue. L'obturateur est muni d'une goupille coulissante montée dans le collecteur, laquelle comporte une ouverture transversale qui s'aligne avec le canal pour laisser passer le flux. Un mouvement de va- et-vient de la goupille dans une direction transversale au flux de matière plastique fondue permet d'ouvrir ou de fermer le débit.
