Abstract

La présente invention concerne un dispositif de chauffage d'un outil de presse (4), qui est monté dans une presse (3) de fabrication de produits entièrement ou partiellement faits de matière plastique ou d'un matériau composite. Ce dispositif est constitué par un noyau (1) en tôle d'acier électrique, un système de bobines (9, 10, 11) placé autour du noyau (1) et une source de tension (12). La source de tension (12) est reliée au système de bobines (9, 10, 11) pour produire un champ magnétique dans le noyau (1) et autour de lui. Le noyau (1) a deux pôles (8a, 8b) entre lesquels on place l'outil de presse (4), et qui sont mobiles l'un par rapport à l'autre pour appliquer une force de presse à l'outil de presse (4) et conduire dans ce dernier (4) le champ magnétique produit. L'invention concerne aussi une presse (3) équipée de ce dispositif de chauffage, et qui est utilisée avec un procédé de fabrication selon lequel l'outil de presse (4) est chauffé par le champ magnétique qui lui est fourni.
