The arrangement of cooling circuits in precision injection molds should follow these core principles:

Firstly, the planning of the cooling system should precede the design of the ejector mechanism;

Secondly, the diameter of the cooling pipes, their center-to-center distance, and the distance from the cavity wall should be scientifically determined;

Furthermore, efforts should be made to minimize the temperature difference between the inlet and outlet of the mold;

Additionally, cooling in the gate area of the mold should be particularly strengthened;

Moreover, the layout of the cooling channels should avoid areas where weld lines are likely to occur on the plastic parts;

Lastly, the arrangement of the cooling channels should facilitate subsequent processing and maintenance cleaning.
