Abstract
An injection mold includes a mold insert frame having several openings extending in an axial direction (z). Each opening accommodates a mold insert encompassing a cavity, suitable to receive during operation melted plastic to form a plastic part. The several openings with the mold inserts are distributed around a center opening of the mold insert frame. A nozzle head is arranged in the center opening of the mold insert frame. A primary melt channel, extending in the axial direction (z), and per cavity a secondary melt channel are each interconnected at a dorsal end to the primary melt channel and at a distal end to a cavity by a nozzle tip attached to the nozzle head. Each mold insert includes a first cooling channel surrounding the cavity and being in fluid communication with a first cooling circuit across the mold insert frame.
