Abstract
La presente invención se refiere a el método para formar una parte de plástico que tiene una porción tubular con un reborde radialmente amplificado en el extremo terminal de la misma, caracterizado porque comprende: a) proveer un molde por inyección que tiene una cavidad formada con una porción de superficie cilíndrica que termina en una ranura puesta para formar el mencionado reborde y un miembro de núcleo removible insertado en la porción cilíndrica y configurado para estar en estrecha proximidad con la superficie cilíndrica adyacente a dicho reborde; b) inyectar un material plástico fundido en la mencionada cavidad para que se extienda dentro de la porción cilíndrica y alrededor del miembro de núcleo, c) separar el miembro de núcleo de la porción cilíndrica a lo largo de una línea que se extiende axialmente de la porción cilíndrica después de que el material plástico en la porción cilíndrica se ha solidificado lo suficiente para conservar su forma tubular, pero antes de que se haya enfriado totalmente para permitir con eso que el material plástico se contraiga alejándose internamente, radialmente, de la superficie cilíndrica; y d) posteriormente proveer para el movimiento relativo de la porción de superficie cilíndrica y la forma tubular de material plástico en un sentido axialmente de la forma tubular para separar la forma tubular de la porción cilíndrica, la proximidad estrecha del núcleo con la superficie cilíndrica adyacente al reborde, provee un espesor de pared reducido en la forma tubular adyacente al reborde para permitir la desviación del reborde internamente durante la citada separación.
