Intelligent Control System Of Wax Injection Machine Based On PLC

Precision casting is a special casting technology, the casting of the surface of the product of good quality and size precision is high.From the present development situation analysis,revestment precision casting technology has a very wide range of application, wants to be a vast developing foreground in the future.More precision casting enterprise products are not limited to the simple components of the production before, but looking for more high-end instrumentation, engines, aviation parts.The process in a wide range of precision casting the Bunsen process, clearly put forward the higher request.This article from the wax injection machine used in the precision casting industry, first of all, according to the working principle of wax injection of wax injection machine temperature control system, hydraulic system for simple design. The predictive control of intelligent control technology to achieve control of the temperature.Are adopted, for example, to control the pressure of traffic flow and pressure setting method of sectional, setting of process parameters through the PLC analog output to control the electro-hydraulic proportional valves to achieve control of the pressure flow.Using the PLC programming software to write the temperature control system, hydraulic system. Finally, using the configuration software software design of the man-machine interface, realize the temperature control system,hydraulic system simulation, real-time monitoring function.By revestment precision precision casting process used in wax injection machine of wax liquid temperature, filling pressure, flow rate of intelligent control, thus improving the quality of wax pattern, increase productivity, wax models for the final product molding wax models of quality assurance.Compared with the traditional wax machine, its performance is stable, theoperation is intelligent.
