以注塑机机筒加热和机筒内物料的塑化过程为研究对象,通过理论分析和实验,分析感应加热温升过程和特点,研究螺杆转速变化对感应加热和电阻加热下注塑机产量和比能耗的影响。结果表明:在一定转速(71、109和144 r/min)下,加热方式对塑化产量影响不大,但感应加热比电阻加热节能(分别为25.04%、19.23%和12.76%)。 Taking the cylinder heating of the injection molding machine and the plasticization process of the material in the barrel as the research object, through theoretical analysis and experiment, the process and characteristics of the temperature rise of the induction heating were analyzed. The effects of the variation of the screw speed on the output and ratio of the injection molding machine under induction heating and resistance heating The impact of energy consumption. The results showed that the heating method had little effect on plasticizing yield at a certain rotational speed (71, 109 and 144 r / min), but the induction heating was more energy saving than resistance heating (25.04%, 19.23% and 12.76% respectively).
