Abstract

Perfeccionamientos en sistemas de moldeo a presión en troquel, del tipo que comprende, en combinación: a) una máquina de moldear que tiene un bastidor con dos pares de conjuntos de cilindros paralelas separados montados en los mismos, sosteniendo cada par de conjuntos una mitad de molde y oponiéndose al otro par de conjuntos portadores de la otra mitad de mol molde, comprendiendo cada conjunto de cilindro de cada par: (i) un pistón estacionario sujeto al bastidor (ii) un vástago de pistón sujeto al pistón coaxial con el mismo, cuyo vástago se extienden a través de una conexión con un pistón opuestos del otro par (iii) un cilindro montado en el pistón y el vástago para efectuar un movimiento alternativo en respuesta a la acción de un fluido incomprimible inyectado en el mismo a cada lado del pistón, (iV) medios que conectan el cilindro de la mitad del molde, por lo que la inyección del fluido en los cilindros en los extremos de las culatas de los pistones fuerza los cilindros y las mitades del molde a unirse y la inyección del fluido en los extremos de las faldillas de los pistones obliga a los cilindros y las mitades de molde a separarse siendo absorbida la fuerza terminal de la apertura de los cilindros por el vástago de los pistones y (v) medios para decelerar los cilindros y eliminar el choque de cierre, caracterizados porque se dota de b) un dispositivo de control térmico evaporativo para los moldes c) un sistema de inyección de metal que comprende medios para inyectar metal en la línea divisoria de los moldes, medios para el desagüe ulterior del metal sin solidificar del bebedero y d) medios directos y rotatorios para retirar el macho antes de abrir el molde.
