A plastic injection tool for producing a closure cap is divided into first and second mold halves that can be moved relative to one another and an injection nozzle is formed in the first mold half, and sliding jaw tool parts are formed in the second mold half, radially outside a central tool core, which can simultaneously be moved in an ejection direction of the produced closure cap and perpendicular to the ejection direction. A respective partial ejection contour of the cap body is formed in the sliding jaw tool parts. An ejector is also provided for ejecting the produced closure cap. Partial injection contours that are different from one another are formed in sliding jaw tool parts, and a sliding jaw tool part is in contact with the tool core in two regions lying after one another in the ejection direction, before the ejection of the closure cap.

Plastic injection tool for producing a closure cap, and method for producing a closure cap

The invention relates to an injection-molding tool () for plastics having a tool core (), an ejector () and a sliding tool portion () for forming an undercut, each of which is displaceable, the sliding tool portion () being displaceable both in the push-out direction (A) of the plastics molded component () produced in the tool and perpendicular to this direction, while the ejector and the tool core () are displaceable in the ejection direction (A) and both the travel of the tool core () and that of the sliding tool portion are derived from the travel of the ejector ().
