  • Patent number: 8469696
    Abstract: The invention relates to a slide mechanism comprising an ejector shaft (2) with a first end portion (2c) attached to a mobile ejector plate (3), a second conical end portion (2a) which ends in a protrusion (2b) coupled to a cam (6), the protrusion (2b) acting as a rotation shaft on which the cam (6) can oscillate; a wedge-shaped slide (5) with a molding portion (5d), an inclined segment (5a) between a push surface (5b) which is in contact with the part to be obtained (10) and a base segment (5c) and a sliding passage (14) which extends through the slide (5) in which at least one portion of the cam (6) slides in parallel with the negative (11a); a fixed sliding support (4) with an axial passage (4a) through which the ejector shaft (2) axially slides, and a slope (4c) on which the inclined segment (5a) of the slide (5) shifts, with a complementary inclination to that of the inclined segment (5a) of the slide.
