Title
(EN) DEVICE AND METHOD FOR MONITORING ALTERNATE LIQUID AND GAS STREAMS IN A TOOL COOLING MACHINE
(FR) DISPOSITIF ET PROCEDE POUR SURVEILLER DES FLUX ALTERNES DE LIQUIDE ET DE GAZ DANS UNE MACHINE DE REFROIDISSEMENT D'OUTILLAGES
Abstract
(EN)
Cooling system for a casting machine (40), in particular for the directional cooling of permanent molds in an injection molding machine, said system comprising: a plurality of cooling fingers (1) in contact with a mold (42) of said molding machine, a cooling machine (30) capable of alternately injecting into said cooling fingers a heat transfer fluid and a pressurized gas in order to remove said heat transfer fluid from said cooling finger, characterized in that said cooling system comprises a plurality of elements (101-108) referred to as flow measuring elements, each flow measuring element being capable of measuring a parameter representative of the flow rate of heat transfer fluid injected into a respective cooling finger.
(FR)
Système de refroidissement pour machine de coulée (40), notamment pour le refroidissement dirigé de moules permanents dans une machine de moulage par injection, ledit système comprenant : une pluralité de doigts de refroidissement (1) en contact avec un moule (42) de ladite machine de moulage, une machine de refroidissement (30) capable d'injecter dans lesdits doigts de refroidissement alternativement un fluide caloporteur et un gaz sous pression pour éliminer ledit fluide caloporteur dudit doigt de refroidissement, caractérisé en ce que ledit système de refroidissement comprend une pluralité d'éléments (101-108) dits de mesure de débit, chaque élément de mesure de débit étant apte à mesurer un paramètre représentatif du débit de fluide caloporteur injecté dans un doigt de refroidissement respectif.
