Abstract
Kühlkörper, der sich an den Gießausgang zweier Nutzformhohlräume bildender Formhälften einer Druckgussvorrichtung anschließt, aus zwei Kühlkörperhälften (1, 2) besteht und an der Trennlinie der Kühlkörperhälften einen Kühlkanal (6) aufweist, der die Form eines sogenannten Waschbretts (3) hat, dadurch gekennzeichnet, dass die Breite (B) des Kühlkanals (6) von seinem Eingang (7) zu seinem Ausgang (8) derart zunimmt und die Stärke (S) des Kühlkanals (6) von seinem Eingang (7) zu seinem Ausgang (8) derart abnimmt, dass der Querschnitt des Kühlkanals (6) im Wesentlichen konstant ist.Heatsink, which adjoins the casting outlet of two mold cavities forming mold halves of a die casting device, consists of two heat sink halves (1, 2) and at the dividing line of the heat sink halves a cooling channel (6), which has the shape of a so-called washboard (3), characterized in that the width (B) of the cooling channel (6) increases from its inlet (7) to its outlet (8) and the thickness (S) of the cooling channel (6) increases from its inlet (7) to its outlet (8) decreases, that the cross section of the cooling channel (6) is substantially constant.
Description
Die Erfindung betrifft einen Kühlkörper gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a heat sink according to the preamble of claim 1.
Ein
derartiger Kühlkörper ist
durch die
Die Aufgabe der Erfindung besteht daher darin, einen Kühlkörper der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei dem die Absaugvorrichtung der Druckgussvorrichtung optimal arbeitet und gleichzeitig Gießmaterial im Kühlkörper eingespart werden kann.The The object of the invention is to provide a heat sink of to create in the preamble of claim 1 mentioned type, in which the suction device of the die-casting device works optimally and at the same time casting material Saved in the heat sink can be.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved with the features of claim 1.
Ein solcher Kühlkörper ermöglicht gleiche Anschnittsgrößen und eine gleiche Querschnittsgröße beim Auslauf.One Such heat sink allows the same gate sizes and a same cross-sectional size in Outlet.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung verlaufen die Zunahme der Kühlkanalbreite und die Abnahme der Kühlkanalstärke stetig.According to one simple, further embodiment of the invention are the increase the cooling channel width and the decrease of the cooling channel thickness steadily.
Die Erfindung wird nun anhand eines Ausführungsbeispiels näher erläutert. Es zeigen:The Invention will now be explained in more detail with reference to an embodiment. It demonstrate:
In
Gemäß der Erfindung
nimmt nun die Breite B jedes Waschbretts
Ein
so gestalteter Kühlkörper kann
universell eingesetzt werden und erfordert keine Einstellungsänderungen
