Abstract:
1. An optical lens mold, comprising: a mold body defining a plurality of injection chambers therein and a cooling channel surrounding the plurality of injection chambers; a magnetic fluid containing magnetic particles and flowing in the cooling channel; a plurality of thermocouples capable of sensing temperatures of the plurality of injection chambers correspondingly; a plurality of electromagnets positioned on the mold body above the cooling channel and corresponding to the plurality of thermocouples; a controlling unit having a predetermined temperature value; and a power source connected to the plurality of electromagnets, wherein the controlling unit is connected to the plurality of thermocouples and the power source, the controlling unit is capable of comparing the predetermined temperature value with temperature values sensed by the plurality of thermocouples to produce temperature deviations, and controlling the power source to supply current to the electromagnets according to the temperature deviations.
