摘要 PAGE IV PAGE III PLC在注塑机控制系统中的应用 摘 要 这次的毕业设计是对注塑机的发展前景，结构组成，工作原理，运行方式，组态设计以及PLC控制技术的介绍。可编程序控制器PLC是微机技术和传统的继电接触控制技术相结合的产物。它的控制系统可靠性高，抗干扰能力强、功耗低、通用性和灵活性强，可编程序控制器以体积小功能强大著称。它不但可以很容易的完成顺序逻辑、运动控制、定时控制、计数控制、数字运算、数据处理等功能，而且可以通过输入输出接口建立与各类生产机械数字量和模拟量的联系，从而实现生产过程的自动控制。本次设计就是通过PLC来实现了对注塑机的运行过程的控制。通过对注塑机各个运行工步的分析，设计出了相应的程序，通过PLC实现了对注塑机各个工作方式的模拟，并对注塑机的整个工作过程进行了组态动画的演示。 关键词：PLC, 注塑机，可编程控制器，组态 Application of the injection molding machine control system of PLC ABSTRACT The machine is introduced ,and the working principle, structure, integrated design of hydraulic system design and PLC control technology.PLC programmable controller is the technology with traditional microcomputer relay contact control technology ,it is the outcome of the combination of the control system has high reliability and anti-interference capability is strong ,low power consumption, high universality and flexibility, programmable controller to small powerful functions, it is not that can easily finish order logic, motion control ,timing, counting control, digital computing and data processing and so on the function, and can be established through input/output interface with various production machinery digital and analog connection ,so as to realize the automatic control of the production process . This design is to achieve control of the injection molding machine is running through the PLC. Through the analysis of the injection molding machine operating step, design the appropriate program, the simulation of injection molding machines work through the PLC, the entire work process of the injection molding machine configuration animation demo.
