Abstract

L'invention concerne un moule métallique de grande dimension, en particulier moule d'injection, du type constitué d'au moins deux parties de moule aptes à être rapprochées et écartées l'une de l'autre, généralement par l'intermédiaire d'une presse pour former, en position fermée du moule, une cavité de moulage, chaque partie (1) de moule, étant une pièce de fonderie affectant la forme d'un bloc, comportant une face (2) de moulage et une face (3) opposée, dite face d'appui de la presse, et étant munie de canaux (4) servant, pour au moins une partie d'entre eux, à la circulation d'un fluide caloporteur, lesdits canaux (4) internes étant venus de moulage avec ledit bloc.The invention relates to a large-sized metal mold, in particular an injection mold, of the type consisting of at least two mold parts able to be brought together and spaced from one another, generally via a press for forming, in the closed position of the mold, a mold cavity, each mold portion (1) being a block-like casting having a molding face (2) and a face (3) ) opposite, said support face of the press, and being provided with channels (4) serving, for at least a portion of them, to the circulation of a coolant, said internal channels (4) being from molding with said block.

Ce moule est caractérisé en ce que lesdits canaux (4) venus de moulage avec ledit bloc sont orientés dans le sens (S) d'ouverture/fermeture de moule et forment un réseau de canaux, parallèles à l'axe d'ouverture/fermeture du moule pour permettre aux parois de canaux (4) d'encaisser les efforts résultant des opérations de moulage.

Figure imgaf001
This mold is characterized in that said channels (4) integrally molded with said block are oriented in the direction (S) of opening / closing mold and form a network of channels, parallel to the axis of opening / closing of the mold to allow the channel walls (4) to absorb the forces resulting from the molding operations.
