Abstract

1. Cierre de aguja para toberas de inyección, en moldes para inyección gobernado por fuerza, en el que el extremo de la aguja de cierre dirigido en sentido contrario al de la tobera de inyección, entra en un taladro de un émbolo dotado de salientes de vástago de émbolo en ambos lados, de un cilindro de accionamiento que se puede poner bajo la acción de un medio de presión por ambos lados, y está fijado es este taladro, caracterizado porque en el taladro del émbolo (34) se ha previsto un tope (36) que actúa en sentido de cierre, para el extremo exterior de la aguja de cierre (40), y porque por el extremo exterior del saliente de vástago de émbolo (18) exterior se puede atornillar un tornillo (48) en un taladro roscado (50) que hay en el extremo de la aguja de cierre, que tiene contacto con un tope (44) que hay en el saliente de vástago de émbolo exterior y que actúa en sentido de apertura. 2. Cierre de aguja para toberas de inyección, según la reivindicación 1, caracterizado porque en el taladro (32, 42, 46) axial que hay en el émbolo (14), se han previsto dos frentes de tope (36,44) opuestos. 3. Cierre de aguja para toberas de inyección, según la reivindicación 1, caracterizado porque se ha previsto un taladro avellanado (42) que parte del extremo del saliente de vástago de émbolo (18) exterior, cuyo fondo (44) constituye el tope que actúa en el sentido de apertura de la aguja de cierre (40). 4. Cierre de aguja para toberas de inyección.
