Abstract

Un mecanismo regulador de presión de fusión para un aparato de moldeo por inyección que tiene una tobera de fusión para presurizar plástico tundido antes de inyectarlo a un molde, el plástico tundido tiene una presión de fusión y un elemento inyector para ingresar el plástico tundido del portador de fusión en el molde, el mecanismo regulador de presión de fusión comprende: un dispositivo regulador de presión dispuesto entre el portador de fusión y el molde, el dispositivo regulador de presión mantiene una presión de fusión prácticamente constante en una cavidad de molde, el dispositivo regulador de presión comprende una válvula reguladora de presión de fluido y una válvula disipadora de presión. La máquina de moldeo por inyección forma partes moldeadas mediante la inyección de material termoplástico tundido en una cavidad de molde a presiones bajas constantes de 41.4 MPa (6000 psi) y menores.
