Abstract

La presente invención se refiere a un dispositivo aseguardor de molde, caracterizado porque comprende: un cilindro asegurador, ajustado deslizablemente con un ariete asegurador cuyo extremo frontal está conectado a un tablero movible, y un pistón de alta velocidad que está ajustado deslizablemente en el ariete asegurador desde su parte posterior; un cilindro soportador que está provisto en paralelo con el cilindro asegurador y un extremo frontal de una barra de un pistón soportador, ajustada allí, está conectado al tablero movible, una trayectoria de aceite que conecta una cámara frontal y una cámara trasera del cilindro asegurador, que está dividido por una sección de pistón del ariete asegurador y una cámara frontal del cilindro soportador, y medios para abrir y cerrar la trayectoria de aceite a la cámara trasera del cilindro asegurador; en donde la suma del área receptora de presión efectiva de la cámara frontal del cilindro asegurador y la cámara frontal del cilindro soportador, es sustancialmente igual al área receptora de presión efectiva de la cámara trasera del cilindro asegurador.The present invention relates to a mold guard device, characterized in that it comprises: a lock cylinder, slidably adjusted with a lock ram whose front end is connected to a movable board, and a high speed piston that is slidably fitted on the lock ram. from its back; a supporting cylinder that is provided in parallel with the securing cylinder and a front end of a supporting piston rod, fitted therein, is connected to the movable dash, an oil path connecting a front chamber and a rear chamber of the securing cylinder, which is divided by a piston section of the securing ram and a front chamber of the supporting cylinder, and means for opening and closing the oil path to the rear chamber of the securing cylinder; wherein the sum of the effective pressure receiving area of the front chamber of the securing cylinder and the front chamber of the supporting cylinder is substantially equal to the effective pressure receiving area of the rear chamber of the securing cylinder.
