Abstract

La presente invención se refiere a un aparato para la manufactura de artículos plásticos moldeados, que consiste de un moldeo de inyección que tiene mitades de molde relativamente móviles que definen una cavidad de molde de la forma o configuración del artículo que se va a moldear, elementos para almacenar una tira de material de película de plástico y alimentar la tira hasta una posición de corte fuera del molde, un elemento de corte en la posición de corte que sirve para cortar un modelo de la tira, un elemento de transferencia al que se aplica succión para recoger y sostener un modelo cortado y alimentarlo al molde abierto y un elemento que opera en las mitades de molde separadas para hacer que el modelo sea empujado lejos del elemento de transferencia y colocado en una superficie adyacente de la cavidad de molde en una mitad de molde para que quede listo para una operación de moldeo; el aparato se caracteriza porque el elemento de corte consiste de una matríz y una almohadilla de presión plana, en donde la matríz tiene un borde o filo cortante que define la forma requerida del modelo que se va a cortar; la almohadilla de presión es de mayor tamaño que el modelo y la matríz y dicha almohadilla se mueven relativamente para quedar situadas en las superficies laterales opuestas de la tira y hacer que la matríz corte un modelo de dicha tira; la matríz esta adaptada para sostener al modelo cortado y se mueve hasta una posición de tranferencia en la que dicho modelo queda separado de la tira; y en que el elemento de transferencia incluye un transportador que tiene una superficie plana mayor que un modelo cortado, al cual se aplica succión para recoger un modelo de la matríz en la posición de transferencia y sostenerlo en contra de dicha superficie, el transportador se mueve desde la posición de transferencia hasta una posición entre las mitades de molde separadas donde se retira la succión aplicada a dicha superficie.
