A method for forming a tool such as a mold includes the steps of initially selecting a cooling channel configuration for the mold. The initial selected cooling channel is evaluated utilizing a computer program. The program analyzes whether there would be local hot or cool spots in the mold with the initially selected channel. The channel is then modified based upon this evaluation. The modified channel is again subjected to the evaluation. This iterative process continues until an acceptable cooling channel configuration is achieved. The invention utilizes a generally helical cooling channel.
L'invention concerne un procédé de formage d'un outil tel qu'un moule. On sélectionne d'abord une configuration de canal de refroidissement du moule. On calcule ensuite ce canal de refroidissement au moyen d'un programme informatique devant déterminer les éventuels points chauds ou froids localisés du moule pourvu du canal considéré. On modifie alors le canal en fonction de ce calcul et on soumet le canal modifié à une nouvelle évaluation. On procède ainsi par itération jusqu'à obtention d'une configuration acceptable du canal de refroidissement. L'invention utilise un canal de refroidissement sensiblement hélicoïdal.
