Abstract

Moitié de moule, en particulier pour la fabrication de disques, comportant, pour des fluides de chauffage et/ou de refroidissement, un système de canaux aménagé en-dessous de la surface de pression, régulièrement réparti sur cette surface et muni d'enceintes collectrices d'amenée et d'évacuation. Le système de canaux 4 est formé par des canaux 8, allant de l'enceinte collectrice d'amenée 6 à l'enceinte collectrice d'évacuation 7 et dont la section transversale globale directement en amont de leur embouchure dans l'enceinte collectrice d'évacuation 7 est réduite par rapport à la section transversale globale la plus petite des canaux lors de leur trajet entre les enceintes collectrices d'amenée 6 et d'évacuation 7.
