Abstract

La présente invention concerne un outil à canal froid pour la transformation de matières thermodurcissables. Outil caractérisé en ce que le canal 106 est relié à la cavité de moule 115 par au moins un passage 116 essentiellement situé dans le plan de joint 103 du moule, et présente une embouchure 107 complètement délimitée par des parois 108 du bloc de canal froid 104 qui ont une direction perpendiculaire ou oblique relativement à la direction d'ouverture A du moule. L'invention est plus particulièrement applicable au moulage de matières thermodurcissables.The present invention relates to a cold runner tool for processing thermosetting materials. Tool characterized in that the channel 106 is connected to the mold cavity 115 by at least one passage 116 essentially located in the parting line 103 of the mold, and has a mouth 107 completely delimited by walls 108 of the cold channel block 104 which have a direction perpendicular or oblique relative to the direction of opening A of the mold. The invention is more particularly applicable to the molding of thermosetting materials.
