Abstract:
1. An injection-molding tool with a baseplate arrangement, which has a runner configured for connection to an injection-molding machine, a central plate, which—in the closed state of the injection-molding tool—lies against the baseplate arrangement in a first separating area and together with said baseplate arrangement forms a skin cavity connected to the runner, and a blank plate arrangement, which—in the closed state of the injection-molding tool—lies against the central plate in a second separating area, with said central plate delimits a number of blank cavities and is configured to be arranged on the movable part of the injection-molding machine, the blank cavities being connected to the skin cavity by way of a respective inflow mouth formed on the central plate for filling with molding material, and being delimited by a respective supporting area, which is formed on the central plate and runs in a continuous annular manner around the inflow mouth, and the supporting areas supporting the created blanks in such a way that, during the opening of the injection-molding tool, in the first separating area the blanks become separated from the skin created in the skin cavity, wherein, for each blank cavity a pin-shaped core having a circular cross-section is fixed in the baseplate arrangement in a freely projecting manner and protruding into the relevant blank cavity through the inflow mouth and wherein an annular inflow cross section, which is positioned coaxially in relation to the core, is formed between the core and the inflow mouth.
