Abstract

La presente invención se refiere a un molde de inyección de plástico, que tiene una mitad de molde externa y un núcleo de molde, que definen entre ellos una cavidad de molde, dicha mitad de molde y núcleo de molde siendo móviles entre una posición moldeadora y una posición abierta, para permitir la remoción de los objetos ahí moldeados, y un elemento de bebedero para permitir llenar la cavidad de molde con un compuesto moldeador mientras está en posición cerrada, la mejora que comprende, en combinación: dicho molde define, como parte de la cavidad de molde, una porción de cámara anular, para recibir el compuesto moldeador para formar una sección anular, relativamente gruesa, que se proyecta al exterior, en el objeto moldeado; un elemento separador para empujar los objetos moldeados, recién formados, fuera del contacto íntimo con el núcleo de molde, el diámetro de una porción del núcleo de molde, a través de la cual se empuja la sección anular por el elemento separador, siendo menor que el diámetro de la porción de núcleo de molde contra la cual se forma la sección anular, por lo cual al enfriar, la sección anular, recién moldeada, puede encogerse al interior y retirarse de la porción de la cámara anular para la remoción del molde sin la necesidad de una acción lateral.
