Abstract

L'invention concerne une plaque de chauffage rapide pour un dispositif de formage à chaud et de durcissement à froid, se présentant sous la forme d'une plaque de formage à chaud et de durcissement à froid disposée entre un dispositif de formage à chaud et un moule. De l'énergie thermique externe, de la vapeur ou de l'huile chaude entre dans une cavité de travail d'une base du dispositif par l'intermédiaire d'un tuyau, l'énergie thermique s'écoule dans la cavité de transport de l'énergie thermique, l'énergie thermique est rapidement absorbée par des pièces à haute densité à l'intérieur de la cavité de la base, l'eau condensée formée après l'absorption d'énergie ou l'huile chaude refroidie est évacuée rapidement de la cavité d'absorption de chaleur par l'intermédiaire de pièces de dissipation de chaleur et de tuyaux d'écoulement, la chaleur est rapidement transférée au moule pour chauffer et former une pièce de travail, un grand nombre de trous d'entrée/sortie d'eau de refroidissement sont formés sur les surfaces latérales gauche et droite, et la pièce à travailler est rapidement refroidie et durcie. La plaque peut être montée sur un dispositif de production pour augmenter la vitesse de production d'un matériau moussant qui nécessite un formage à chaud et un durcissement à froid.
