Study On Injection Energy Consumption In The Injection Molding Machine Experimental System

Injection molding, a preferred method to produce the plastic products in batches, has become an important molding method in plastic processing. It has been experiencing a rapidly developing period, whereas the problem of energy consumption of injection molding machine are presented more and more obviously. Solving of this problem is related to the development of the whole plastic processing industry.This thesis is mainly about the effect of injection parameters on the injection energy comsumption.The injection molding machine experimental system including the injection molding machine, sensors system and data recording system is established with teachers, which settles the bedrock of the following researching work. Injection Energy Comsumption per Yield is considered as the evaluating standard of energy comsumption. Meanwhile, Taguchi orthogonal experiment is designed to study the effect of injection parameters on energy consumption. According to the analysis of its result, the ranking about the influences of various process parameters to energy consumption is reached and the optimized parameter combination is obtained to minimize theenergy consumption. The effect of various process parameters--nozzletemperature, ram velocity and packing pressure, which influence most on the energy comsumption in injection process, are discussed by single factor experiments. According to the analysis of the results, the relationships between each parameter and injection power cost as well as product mass are investigated so as to inquire the effects of various parameters on Injection Energy Comsumption per Yield.Non-linear relationship between the injection process parameters and Injection Energy Comsumption per Yield is established through the artificial neural network which is trained by the training samples from Taguchi experiment and testified by the test samples from single factor experiments. The optimization of injection parameters is performed through the ANN Model and tiny increment scouting method. The secondary orthogonal experiment is arranged and its result is simulated by the ANN Model. According to the analysis of the result, the further-optimized parameter combination is obtained to further minimize the energy consumption.In conclusion, here some elementary studies of the relationship between injection parameters and injection energy consumption of injection molding machine are proposed. It will make a good basis for further study in the future.
