Component part for an injection molding tool

A component part (1) for an injection molding tool (100),

• a) with a distributor (2) that includes a first distributor plate (10) having a top side (11) and an underside (12),
• b) with at least two material pipes (21, 22, 23, 24, 25, 26, 27, 28, 29) that are aligned crosswise relative to the underside (12) of the first distributor plate (10) and connected on the underside (12) to the first distributor plate (10),
• c) wherein each material pipe (21, 22, 23, 24, 25, 26, 27, 28, 29) has a flow channel (31, 32, 33, 34, 35, 36, 37, 38, 39) configured therein, and
• d) wherein feed channels (41, 42, 43, 44, 45, 46, 47, 48, 49) are configured in the first distributor plate (10) opening on the underside (12) into the flow channels (31, 32, 33, 34, 35, 36, 37, 38, 39) of the material pipes (21, 22, 23, 24, 25, 26, 27, 28, 29),
• e) wherein the feed channels (41, 42, 43, 44, 45, 46, 47, 48, 49) are configured as open on a top side (11) of the first distributor plate (10),
• f) wherein the first distributor plate (10) is configured monolithically with the material pipes (21, 22, 23, 24, 25, 26, 27, 28, 29);
• g) wherein a first heating device (80) is allocated to the material pipes (21, 22, 23, 24, 25, 26, 27, 28, 29);
• f) the first heating device (80) includes at least one cartridge heater (95) that is inserted into a recess (92) in a material pipe (21, 22, 23, 24, 25, 26, 27, 28, 29) that is parallel relative to the flow channel (31, 32, 33, 34, 35, 36, 37, 38, 39) of the material pipe (21, 22, 23, 24, 25, 26, 27, 28, 29);
• and
• h) wherein the recess (92) for the cartridge heater (95) continues through the first distributor plate (10), wherein a connection cable of the cartridge heater (95) is disposed outside of the first distributor plate (10) and outside of the material pipe (21, 22, 23, 24, 25, 26, 27, 28, 29).
