Injection mold, for very small molded components, has slides flanking the longitudinal axis to form the molding cavity between them, to be opened and closed in a radial movement by operating cams

摘要

Injection mold has at least two slides flanking a longitudinal axis, and with relative movement between them, to form the molding cavity for at least one molding. The slides carry one or more axial and/or radial pins, to form passage channels in the molding, together with the mold opening mechanism. The slides are moved by two opening/closing cams. The injection mold has at least two slides (5A,5B) flanking a longitudinal axis (X,X'), and with relative movement between them, to form the molding cavity for at least one molding (1). The slides carry one or more axial (2) and/or radial (3,4) pins, to form passage channels in the molding, together with the mold opening mechanism. The slides are moved by two opening/closing cams (I,II), operated by shafts (10,11) moving axially in one direction or the other. The cams act on structured sections (15,23) of the slides, to give them a simultaneous radial movement in a mold opening or closing action.
