Beschreibung
Zusammenfassung:	The invention relates to a device for the injection moulding of a moulded part (2) comprising a void (1), wherein a projectile (10) can be positioned at a fluid injection nozzle (8) in the region of a fluid aperture (9), which projectile (10) 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 (8) comprises a section (11) entering into a cavity (5) of a mould, which section (11) is free from any undercut in a direction (E) of insertion of the fluid injection nozzle (8) into the cavity (5), wherein an angle (α) is arranged between a longitudinal axis (L) and the direction (E) of insertion.
