基于PLC的注塑机液压系统的控制设计
Design of Hydraulic Control System for Injection Molding Machine Based on PLC
摘要
Abstract
The working principle about hydraulic system of injection molding machine and the working requirement are introduced,then the electrical control system including hardware and program based on the PLC is designed.The programming way of Start-Retention-Stop Electric Circuit to modular programming is employed.After drawing sequential function chart,modularized programming is achieved by using PLC programming components,therefore the program is concise,simple debugging,easy to modify,and has strong versatility,which is suitable for any type of PLC.The finding shows that：the modified electrical control system can greatly improve the production precision,working performance,maintenance and stability of injection molding machine,improve the quality and production efficiency of the products.关键词
