Abstract

EL PRESENTE INVENTO SE RELACIONA CON UN DISPOSITIVO PARA PRODUCIR ARTICULOS PLASTICOS DE FORMA HUECA POR MOLDEO DE INYECCION INCLUYENDO EL DISPOSITIVO UNA TOBERA (10) PROVISTA DE UNA PRIMERA ABERTURA DE ENTRADA PARA EL PLASTICO FUNDIDO PROVENIENTE DE LA MAQUINA DE MOLDEO POR INYECCION Y UNA SEGUNDA ABERTURA DE ENTRADA PARA UN GAS, MEDIOS PARA DIRIGIR GAS HACIA EL PLASTICO FUNDIDO Y UNA ABERTURA DE SALIDA A TRAVES DE UNA PUERTA QUE SE PUEDE CONECTAR CON UN ESPACIO DE MOLDEO. LA SEGUNDA ABERTURA DE ENTRADA SE COMUNICA A TRAVES DEL CONDUCTO (28) CON UN ACUMULADOR DE GAS (29) QUE TIENE UN VOLUMEN CONSTANTE Y EN EL QUE EL GAS TIENE UNA PRESION SUBSTANCIALMENTE CONSTANTE. DICHA CONEXION TAMBIEN TIENE UNA MARIPOSA VARIABLE (32) POR MEDIO DE LA CUAL PUEDE AJUSTARSE EL FLUJO DE GAS A TRAVES DEL CONDUCTO.
