Title: INJECTION MOLD TEMPERATURE CONTROL METHOD AND DEVICE BASED ON POSITIVE AND NEGATIVE INPUT PREDICTIVE CONTROL
Abstract:
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.
