Patent ID: 8469696

Claim:
A slide mechanism for the molding and ejection of parts molded with negatives for an injection mold, the slide mechanism comprising at least one ejector shaft with a first end portion attached to a mobile ejector plate which shifts in an axial plane, and a second end portion coupled by means of a coupling element to a slide comprising a molding portion provided with a geometry of at least one negative of a molded part which extends through the slide, a base segment and a push surface which are in contact with the molded part during molding, as well as a radially inclined segment with respect to said axial plane; a fixed sliding support with a slope with a complementary inclination with respect to the inclination of the inclined segment of the slide and on which the inclined segment of the slide shifts, and with a base provided with an axial guiding passage through which the ejector shaft axially slides; wherein the slide comprises a sliding passage which extends through the slide at least partially and in parallel with the negative; wherein the coupling element is attached to the second end portion of the ejector shaft and fits at least partially in a sliding manner in the sliding passage; and wherein the coupling element is a cam, and the second end portion of the ejector shaft ends in a protrusion coupled to the cam, the protrusion acting as a rotation shaft on which the cam can oscillate.
