Abstract
La presente invención se refiere a mejoras en método para hacer un cuerpo hueco a partir de resina fundida, en un sistema de moldeo por inyección que incluye un molde que tiene una abertura para inyección y una boquilla e inyección, caracterizada por el método comprenden los pasos de: inyectar una cantidad de resina fundida suficiente para la preparación del cuerpo hueco, desde la boquilla de inyección a través de la abertura para inyección y a lo largo de una trayectoria de flujo de resina en el olde; inyectar un gas a presión en el molde para distribuir la resina fundida sobre la superficies internas del molde, mediante una abertura para que se forma en ellas en comunicación con el interior del cuerpo hueco, enfriar el cuerpo hueco a una temperatura inferior al punto de reblandecimiento de la resina, cortar un agujero en la resina fría en la abertura para gas para descargar la presión del cuerpo hueco, abrir el molde para sacar el cuerpo hueco.The present invention relates to improvements in method for making a hollow body from molten resin, in an injection molding system including a mold having an opening for injection and a nozzle and injection, characterized by the method comprise the steps de: injecting a quantity of molten resin sufficient for the preparation of the hollow body, from the injection nozzle through the injection opening and along a resin flow path in the olde; injecting a gas under pressure into the mold to distribute the molten resin on the internal surfaces of the mold, through an opening so that it forms in them in communication with the interior of the hollow body, cool the hollow body to a temperature below the softening point of the resin, cut a hole in the cold resin in the gas opening to relieve the pressure of the hollow body, open the mold to remove the hollow body.
