Injection mold with a side gate nozzle

An injection mold (1) comprising

• a. a mold insert frame (2) having several openings (3) extending in an axial direction (z) accommodating in each opening (3) a mold insert (4) encompassing a cavity (5), suitable to receive during operation melted plastic to form a plastic part, wherein
• b. the several openings (3) with the mold inserts (4) are distributed around a center opening (6) of the mold insert frame (2);
• C. a nozzle head (7) arranged in the center opening (6) of the mold insert frame (2) comprising a primary melt channel (8), extending in the axial direction (z), and per cavity (5) a secondary melt channel (9) each interconnected at a dorsal end to the primary melt channel (8) and at a distal end to a cavity (5) by a nozzle tip (10) attached to the nozzle head (7), wherein
• d. each mold insert (4) comprises a first cooling channel (11) surrounding the cavity (5) and being in fluid communication with a first cooling circuit (12) across the mold insert frame (2), and
• e. a second cooling channel (13), wherein the first cooling channel (11) encompasses the cavity (5) distal from the nozzle tip (10) and the second cooling channel (13) encompasses the cavity (5) adjacent to the nozzle tip (10) and wherein the second cooling channel (13) is:
• f. in fluid communication with a second cooling circuit (14) across the mold insert frame (2) and/or
• g. the first and the second cooling channel (11, 13) are interconnected to the first cooling circuit (12).
