Abstract

Moule pour la réalisation d’une pièce en matériau de moulage La présente invention concerne un moule (6) de réalisation d’une pièce en matériau de moulage comprenant un premier élément (10) comprenant une première surface de moulage (20). Le premier élément (10) comprend des première et deuxième portions (10A, 10B), la première portion (10A) définissant une première partie (20A) de la première surface de moulage et présentant un logement (30) présentant, dans un plan de coupe transversal, un premier rayon de courbure minimal, et la deuxième portion (10B) définissant une deuxième partie (20B) de ladite première surface et étant agencée dans le logement. La première surface de moulage comprend une zone de moulage (26) présentant, dans ledit plan de coupe, un deuxième rayon de courbure minimal et étant formée au moins en partie par la deuxième partie de ladite première surface, la valeur du deuxième rayon de courbure minimal étant strictement inférieure à la valeur du premier rayon de courbure minimal. Figure pour l'abrégé : figure 1Mold for producing a part in molding material The present invention relates to a mold (6) for producing a part in molding material comprising a first element (10) comprising a first molding surface (20). The first element (10) comprises first and second portions (10A, 10B), the first portion (10A) defining a first part (20A) of the first molding surface and presenting a housing (30) presenting, in a plane of transverse section, a first minimum radius of curvature, and the second portion (10B) defining a second part (20B) of said first surface and being arranged in the housing. The first molding surface comprises a molding zone (26) having, in said cutting plane, a second minimum radius of curvature and being formed at least in part by the second part of said first surface, the value of the second radius of curvature minimum being strictly less than the value of the first minimum radius of curvature.
