[Abstract]The injection molding industry is in the stage of rapid development, in the actual engineering development, the use of quantitative pump accounts for the vast majority, and its energy consumption is large, which not only increases the operation cost, but also increases the maintenance cost. It is urgent to combine the existing control system, simulate the similar system of quantitative pump and variable displacement pump, and develop a new application mode, so as to achieve the purpose of energy saving and emission reduction, And through program optimization to improve the operation efficiency, to achieve the purpose of improving work efficiency and improving the quality of work results. In this paper, the working principle of injection molding machine, development, the principle of servo machine, transformation direction and application space, the overall technical advantages and characteristics of servo injection molding machine and other multi angle and multi space are discussed effectively, trying to find an effective scheme for energy-saving transformation of servo machine, which can not only promote the healthy development of injection molding industry, but also achieve the purpose of improving the efficiency of factory work.

注塑机是进行塑料加工的最主要设备,其用电量占到塑料加工企业整体用电量的3/4,在部分企业中其比重甚至可以超过4/5,既是企业运营成本中的大部分开支,也会对所处城市、区域的用电量和用电承载负荷造成困扰,在用电和生产时产生的废物还会对周边环境和大气状态构成一定威胁;而伺服机系统是指以物体的位置、角度、移动速度为基本控制要素,可以实现根据对应物体任意的位置变化,进行自动化的控制,由伺服驱动器和伺服电机共同组成,是在原有的变频技术基础上进行技术的优化、更新和延伸,既可以实现根据速度进行加工物的有效跟踪和控制,还可以提高加工生产的精确度、产出效率,保证较稳定的产出质量。……
