摘　　要：温度的准确控制是保证注塑产品质量的重要因素.针对传统注塑机温度控制系统温控波动范围大、超调量大等缺点,提出了基于模糊控制的注塑机温控系统,发挥了PLC控制灵活、编程方便、适应性强的优点,提高了注塑机料筒温度控制精度.The accurate control of the temperature is a key factor for ensuring the quality of the plastic products. Aiming at the shortcomings of the conventional temperature control system of the injection molding machine, such as largish fluctuation range of temperature control and great overshoot, and so on. A temperature control system based on fuzzy control is put forward. It makes full use of the advantages of PLC such as flexible control, convenient programming and stronger adaptability,thus improving the accuracy of the temperature control of charging barrel of the injection molding machine.
