Abstract: A device for reworking an injection-molded component that features a support component, on which an injection-molded component is supported for the reworking operation in the region of a supporting surface and a separating tool for separating one or more sprue sections on the injection-molded component positioned on the support component, wherein the separating tool is realized with a cutting tool, in which one cutting edge is arranged on the support component and an additional cutting edge assigned to said cutting edge is arranged on a displaceable component that can be displaced relative to the support component and the cutting edge arranged thereon together with the additional cutting edge, namely in such a way that one or more sprue sections can be separated by means of the cutting edge and the additional cutting edge is provided. In addition, an arrangement with multiple devices for reworking an injection-molded component is proposed.
