摘要
The invention relates to an injection-molding device for producing multi-component moldings from a thermoplastic molding compound, comprising a mold, forming a first article cavity, comprising means for filling the first article cavity with the thermoplastic molding compound, comprising an injection device for injecting a fluid against a projectile to be driven, wherein the injection device comprises a projectile carrier with at least one injection nozzle and with at least one projectile receptacle for a projectile as a displacer for the molding compound. The injection-molding device also comprises a mold insert, which forms a continuation of the first article cavity and encloses the projectile carrier, wherein the projectile carrier forms with the mold insert a second article cavity that can be filled with the molding compound, wherein the mold insert has a separate sprue and wherein the second article cavity of the mold insert can be sealed off for a time with respect to the first article cavity by means of movable mold parts. The invention also relates to a method for producing multi-component moldings by using the injection-molding device.
