The invention concerns a method for making a material-shaping tool, in particular by hot pressing or injection moulding. The tool (2) consists of an integral assembly of sections (35, 36, 37, 38, 39, 40) mutually adjacent along junction surfaces (41, 42, 43, 44, 45, 46, 47, 48, 49, 50). Grooves (51, 52, 55, 56, 58, 59) provided in said junction surfaces (41, 42, 43, 44, 45, 46, 47, 48, 49, 50) and passages (53, 54, 57, 30, 62, 63, 64, 65, 66, 67) provided through said sections (36, 37, 38, 39) define a circuit (13) for circulating a heating medium. Each section (36, 37, 38, 39, 40) can be designed and produced, for example by moulding or machining in a bloc of heat-conducting material, so as to ensure an optimal configuration of the heating medium circuit (13) in the tool (2).
La présente invention concerne la réalisation d'un outil destiné au formage d'une matière, en particulier par emboutissage à chaud ou injection-moulage. L'outil (2) est constitué d'un assemblage solidaire de tranches (35, 36, 37, 38, 39, 40) mutuellement jointives le long de faces de jonction (41, 42, 43, 44, 45, 46, 47, 48, 49, 50). Des gorges (51, 52, 55, 56, 58, 59) aménagées dans ces faces de jonction (41, 42, 47, 48, 49, 50) et des passages (53, 54, 57, 30, 62, 63, 64, 65, 66, 67) aménagés à travers les tranches (36, 37, 38, 39) définissent un circuit (13) de circulation d'un fluide caloporteur. Chaque tranche (35, 36, 37, 38, 39, 40) peut être projetée et réalisée, par exemple par moulage ou par usinage dans un bloc de matière thermoconductrice, de façon à respecter une conformation optimale du circuit (13) de fluide caloporteur dans l'outil (2).
