摘要： A method for producing injection-molded parts by a two-component injection-molding technique in which a first material component is injected into a mold cavity and is displaced into peripheral regions of the mold cavity by injecting a second material component. The first material component is injected into a partial region of the mold cavity at a first gating point and the second material component is injected into the mold cavity at a second gating point and, as a result, the first material component is acted upon by the second material component and displaced in the direction of the regions of the mold to be filled with the first material component. The first material component is thereby displaced into regions of the mold at the wall, and the second material component is introduced in those regions of the mold as a core material and completely into other regions of the mold.

摘要： An injection-molding machine having a stack mold for producing injection-molded parts, has first and second external mold parts and a rotatably mounted central block, the external mold parts each having a distribution plate having a hot runner for the injection material, and mold cavities being formed between molding regions on inner sides of the mold plates of the external mold parts and molding regions being formed on mold plates on opposite outer sides of the central block. At least one gripper is provided. The mold plates of the external mold parts and the central block are held detachably in place. The mold plates of the external mold parts are positionable on the distribution plates to correspond to respective feed channels, and the mold plates of the central block are positionable on the central block to correspond to respective positions of the mold plates of the external mold parts.

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.
