Device and method for the injection molding of a molded part comprising at least one void

The invention relates to a device for the injection moulding of a moulded part comprising a void, wherein a projectile can be positioned at a fluid injection nozzle in the region of a fluid aperture, which projectile can be caused to flow in the direction of the longitudinal axis (L). To allow the production of moulded parts with enclosed voids in a better way the invention is characterized in that the fluid injection nozzle comprises a section entering into a cavity of a mould, which section is free from any undercut in a direction (E) of insertion of the fluid injection nozzle into the cavity, wherein an angle (α) is arranged between a longitudinal axis (L) and the direction (E) of insertion.
