INJECTION MOLD TEMPERATURE CONTROL METHOD AND DEVICE BASED ON POSITIVE AND NEGATIVE INPUT PREDICTIVE CONTROL

摘要

An injection mold temperature control method and device based on positive and negative input predictive control. In the injection mold temperature control method, by means of an algorithm, a cooling unit of a mold temperature controller stops a temperature output during the temperature rise process of a mold; and a heating unit of the mold temperature controller stops a temperature output during the cooling process of the mold; accordingly, energy consumption is reduced, the temperature control result is stable, and costs are also reduced.
