Abstract

Mecanismo de corredera que comprende un eje expulsor (2) con una primera parte extrema (2c) unida a una placa expulsora móvil (3), una segunda parte extrema (2a) cónica que finaliza en una protuberancia (2b) acoplada a una leva (6), actuando la protuberancia (2b) de eje de rotación en el que la leva (6) es susceptible de oscilar; una corredera (5) en forma de cuña, con una parte de moldeo (5d), un tramo inclinado (5a) entre una superficie de empuje (5b) que está en contacto con la pieza a obtener (10) y un tramo base (5c) y un paso de deslizamiento (14) que atraviesa la corredera (5) en la que se desliza al menos una parte de la leva (6) paralelamente al negativo (1 1 a); un soporte de deslizamiento (4) fijo con un paso (4a) axial por el que se desliza axialmente el eje expulsor (2), y una rampa (4c) sobre la que se desplaza el tramo inclinado (5a) de la corredera (5) con una inclinación complementaria a la del tramo inclinado (5a) de la corredera.
