1. The layout of the precision injection mold cooling system should be prior to the demoulding mechanism;
2. Reasonably determine the distance between the diameter center of the cooling pipe and the cavity wall;
3. Reduce the temperature difference between the water entering and exiting the mold;
4. Cooling should be strengthened at the gate of the precision injection mold;
5. The layout of the cooling water channel should avoid the parts where the plastic parts are prone to welding marks;
6. The layout of the cooling water channel should be convenient for processing and cleaning.
