Abstract
This paper introduced application of PLC in inject plastics machine.By analyzing the process of SZ—250g inject plastics machine and the hydraulic system,PLC control system design is accomplished.PLCis used in the control of inject plastics machine,we can make the program to control the process.Not only induce the reliability of electrical control and the operating efficency,but also modify data easily、induce the flexibility of the system、lift the quality of injecting.
The principle of mold—adjustment was analyzed and the hardware demand and software realization of automaticmold—adjustment based on PLC control in toggle clamping system of injection machine were studied.It characterizes simplemethod and high performance-price ratio with the satisfied practice applications.
