  • the molten metal can be introduced from the storage container via at least one filling bore into the collection chamber. While the piston moves back to its initial position, the molten metal flows through the preferably formed in the piston and particularly preferably the piston penetrating filling bore in the piston simultaneously released from the collection chamber. It has been shown that in this way a refilling of the collection chamber can be achieved very quickly and reliably.

  • the cross section of the valve body is smaller than the cross section of the cylinder bore, so that the molten metal can freely flow around the valve body within the cylinder bore.

Abstract

L'invention concerne un dispositif de transport pour un bain de métal fondu dans une unité d'injection sous pression, par exemple dans une machine de coulée de métal, qui possède un récipient de réserve pour le métal fondu et un canal de transport dans lequel le métal fondu est acheminé à l'empreinte d'un moule. Le canal de transport comprend un alésage cylindrique, dans lequel est disposé un piston de manière mobile axialement. Pour le métal fondu est prévue une chambre collectrice depuis laquelle le métal fondu est introduit dans l'empreinte du moule sous l'effet d'un décalage axial du piston, à travers une conduite de poursuite. Entre la paroi extérieure du piston et la paroi intérieure de l'alésage cylindrique est formé un espace annulaire qui communique avec la chambre collectrice par au moins un alésage de remplissage. L'alésage de remplissage peut être fermé à son extrémité débouchant dans la chambre collectrice au moyen d'un corps de soupape, qui est relié à une queue de soupape réglable, disposée de manière à pouvoir coulisser dans un alésage axial du piston.
