Abstract
An injection-moulding tool (2) for producing an in particular thin-walled plastics component, comprising: —at least two tool elements (1, 1′, 1″), wherein the at least two tool elements (1, 1′, 1″), in a closed position of the injection-moulding tool (2), are moved against one another at least in sections so as to form at least a subregion of a shape-imparting tool cavity (3) of the injection-moulding tool (2), wherein—the at least two tool elements (1, 1′, 1″) each have at least one shape-imparting contouring structure (4, 4′, 4″) which delimits the tool cavity (3) at least in sections, wherein—on at least one tool element (1, 1′, 1″), adjacent to the contouring structure (4, 4′, 4″), there is formed at least one ventilation structure (5) for ventilating the tool cavity (3) in the closed position of the injection-moulding tool (2).
