Abstract

Die Erfindung bezieht sich auf eine Vorrichtung (10) zum Entlüften einer Giessform, insbesondere in Form eines Chill-Vents, mit zwei einander gegenüberliegenden und zueinander form- und funktionskomplementären Formhälften (12, 14), die in ihren zueinander weisenden Flächen (16) jeweils eine Mehrzahl von zueinander im Wesentlichen parallel und zur Strömungsrichtung im Wesentlichen quer verlaufenden Erhebungen (18) und/oder Vertiefungen (20) aufweisen, dergestalt, dass sich bei aufeinander gesetzten Formhälften (12, 14) zwischen den Formhälften (12, 14) zumindest teilweise ein Spalt (22) mit einem Einlass (24) und einem Auslass (26) ausbildet, der insbesondere waschbrett-, labyrinth- und/oder mäanderförmig ist, und durch den beim Füllen der Giessform aus der Giessform verdrängte Luft und überschüssiges schmelzflüssiges Material strömen kann, dadurch gekennzeichnet,dass zumindest eine oder vorzugsweise jede Formhälfte (12, 14) durch mehrere, in Längsrichtung der Formhälfte (12, 14) nebeneinander angeordnete und lösbar befestigte, vorzugsweise miteinander verbundene Segmente (12a, 12b, 12c, 14a, 14b, 14c) gebildet ist.

The invention relates to a device (10) for venting a casting mold, in particular in the form of a chill vents, with two mold halves (12, 14) which are opposite each other and complementary in terms of shape and function and in their mutually facing surfaces (16) in each case a plurality of elevations (18) and / or depressions (20) that are substantially parallel to one another and essentially transverse to the flow direction, such that, when the mold halves (12, 14) are placed on one another, at least partially between the mold halves (12, 14) forming a gap (22) having an inlet (24) and an outlet (26) which is particularly washboard, labyrinth and / or meandering, and through which air and excess molten material displaced during filling of the mold from the mold can flow , characterized in that at least one or preferably each mold half (12, 14) by a plurality, in the longitudinal direction of the Formhäl (12, 14) arranged side by side and releasably secured, preferably interconnected segments (12a, 12b, 12c, 14a, 14b, 14c) is formed.
