摘要： A brush manufacturing machine having an injection mold is used to manufacture multi-component brush elements made of plastic, in particular for toothbrushes. The injection mold has a nozzle-side mold plate and an ejector-side mold plate, in which mutually allocated mold cavities (8) are provided, the injection mold being formed as a turning tool, having a turning part (index plate) that can be rotated about an axis of rotation and that is allocated to the ejector-side mold plate (3), said turning part having partial cavities (8b) of the mold cavities of the ejector-side mold plate (3). The turning part, formed as an index plate (4), has at least three carrier arms (11) that have the partial cavities (8b) and that are situated approximately radially in relation to the axis of rotation (14) of the rotatable turning part. The mold cavities (8) are situated with their longitudinal extension approximately tangential to the axis of rotation (14). This arrangement of the mold cavities results in a small space requirement, even given a large number of mold cavities, so that despite a high number of mold cavities, comparatively small injection-molding machines can be used, with a corresponding cost advantage. A brush element delivery station (7) is accessible when the mold is closed for a removal of brush elements (9). In this way, the time required for the injection process or processes is simultaneously also exploited in order to cool and to remove the brush elements.
