Abstract

LA INVENCION SE REFIERE A UN METODO DE MOLDEO DE POLIMEROS POR INYECCION DINAMICA ELECTROMAGNETICA, Y AL APARATO PARA EL MISMO. EL CILINDRO DE CARGA (7) Y EL TORNILLO (9) ASI COMO SUS COMPONENTES ASOCIADOS PARA LLEVAR A CABO EL PROCESO DE PLASTIFICACION, INYECCION Y MANTENIMIENTO DE LA PRESION DEL POLIMERO, SE DISPONEN TODOS EN LA CAVIDAD INTERNA DE UN CUERPO METALICO MOVIL (2) ACCIONADO PARA GIRAR DE FORMA PULSATORIA MEDIANTE UN DEVANADO ELECTROMAGNETICO (1). MIENTRAS EL TORNILLO Y EL CUERPO MOVIL METALICO ESTAN GIRANDO SIMULTANEAMENTE DE FORMA PULSATORIA, EL TORNILLO ESTA EFECTUANDO AL MISMO TIEMPO DESPLAZAMIENTO AXIALES PULSATORIOS, POR LO QUE LOS PROCESOS DE PLASTIFICACION, INYECCION Y MANTENIMIENTO DE LA PRESION, SE LLEVAN A CABO EN UN ESTADO DE OSCILACION PERIODICA. ESTE METODO Y ESTE APARATO DE MOLDEO POR INYECCION TIENEN LA VENTAJA DE UN PEQUEÑO VOLUMEN, REDUCIDO PESO, BAJO COSTE DE FABRICACION, BAJO CONSUMO DE ENERGIA, BAJA PRODUCCION DE RUIDO, AMPLIA ADAPTABILIDAD A LOS MATERIALESY EXCELENTE CALIDAD DE LOS PRODUCTOS MOLDEADOS.
