Abstract

A tool for the multicomponent injection molding of brush bodies and more particularly of toothbrush bodies, including two tool parts able to be moved towards and away from each other and which between them jointly define a plurality of mold cavities. In accordance with the invention at least two of the mold cavities are permanently associated with different components. The at least one mold cavity, which is permanently associated with the first component to be injected, has a recess in the shaping surface of the one tool part, such recess being able to be shut off by an insert element, which is able to be moved in relation to this tool part and on which a head is formed, which, when the mold cavity is shut off by the insert element, extends into the cavity. The insert element is mounted on a carrier such that a premolding molded in this mold cavity, which is associated with this component to be injected firstly, may be moved into another mold cavity associated with another component. A tool of this type may be produced in a comparatively simple manner and more particularly does not need any rotatable tool halves or any exact symmetry of the mold cavity part in a rotatable tool half.
