Injection mould with temperature-control system

An injection mould comprising a cavity for receiving a plastics melt and comprising a temperature-control system,

• the cavity comprising a plate-shaped first part extending in a first and second direction and a plurality of hollow cylindrical second parts which are arranged next to one another perpendicularly to the first part,
• the temperature-control system comprises temperature-control channels divided into channel portions for transporting a temperature-control medium, and a first and a second temperature-control medium connection,
• wherein at least one first channel portion is arranged in parallel with the first part, several second channel portions are connected by a first end to the first channel portion and are connected by a second end in each case to a first end of a third channel portion,
• the third channel portions are connected by a second end to a fourth channel portion, arranged in parallel with the first part, in each case one of the second channel portions and the third channel portion connected thereto are surrounded at least in part by one of the second parts of the cavity, and in the direction of a longitudinal extension of the second channel portions,
• wherein the longitudinal extension of the second channel portions and a longitudinal extension of the third channel portions are both perpendicular to a longitudinal extension of the first channel portion and parallel to a third direction being perpendicular to the first and to the second direction, and
• the first end of the second channel portions being respectively arranged on a first side of the plate-shaped first part with respect to the third direction and the second end of the second channel portions being respectively arranged on a second side, opposite the first side, with respect to the third direction, of the plate-shaped first part,
• wherein a cooling circuit is established comprising the first channel portions, the second channel portions, the third channel portions and the fourth channel portions, wherein the injection mould comprises more than one of said cooling circuit, wherein the cooling circuit are connected in parallel towards each other in respect of the supply of temperature-control medium by means of a distributor plate,
• wherein the at least one fourth channel portion is respectively arranged at a further distance from the centre axis of the second parts associated therewith than the at least one first channel portion.
