The apparatus for injection molding a plastics component with a threading, and especially an inner threading, has a threaded core (8) which rotates round its longitudinal axis, so that it can be unscrewed from the molded threading of the molding. The threaded core (8) has a concentric cogwheel (5) which meshes with a sliding rack (6) as its drive. During the rotation the core (8), it is held firmly axially while the molding is moved axially, or vice versa. The threaded core (8) slides on a fixed c (4). A holding and ejection unit is at the molding. The apparatus has a rotating component between the two half-molds, for multi-component material injection and especially a twin-component material injection molding action. The threaded core (8) and rack (6) are at the rotating component. The rack (6) has a sliding unit with a carrier, and has a counter unit at both ends to b coupled to the sliding system carrier. The sliding mechanism has a piston/cylinder unit, with the carrier at the piston, fitted one of the half-molds. |
