Abstract
ESTA INVENCION EXPONE UN ANILLO DE COMPUERTA MEJORADO PARA UN SISTEMA DE MOLDEO POR INYECCION DE MULTI-CAVIDAD. EL ANILLO DE COMPUERTA TIENEN UN HUECO CENTRAL A TRAVES DEL CUAL SE EXTIENDE LA COMPUERTA. EL CONDUCTO DE FUSION SE EXTIENDE A TRAVES DEL ANILLO PARA UNIR UNA PORCION ALARGADO DEL HUECO CENTRAL ALREDEDOR DE LA COMPUERTA. EN EL ANILLO DE ACUERDO CON LA INVENCION EL CONDUCTO DE FUSION SE RAMIFICA EN DOS BRAZOS CON PLIEGUES CURVADOS SUAVEMENTE LOS CUALES SE DIRIGEN A LOS LADOS OPUESTOS DE LA COMPUERTA. ESTO ELUDE EL PROBLEMA DE RAYAR Y BAJAR EL FLUJO DE FUSION SOBRE EL LADO OPUESTO DE LA COMPUERTA.
