Multi-Channel Temperature Control Research Of Die Casting Mould Based On Fuzzy Algorithm

In recent years,the areas of industry including automobile,shipbuilding,electrical machine,instrumentation and aviation technology are developing rapidly,which makes our country's manufacturing technology,manufacturing process and manufacturing equipment level get great developments.At the same time,the level of pressure casting technology also has been greatly improved.Die-casting mould is accounted for a big category of mould.The working condition of die-casting mould is relatively harsh.Temperature control technology of die casting mould is afrecting the mold service life,inner quality and parts of molding as an important factor.Whether the temperature can be successfully controlled within the required range relates to the success or failure of the whole production process.The temperature control of the mold is essential for efficient and economical production of high quality die casting.Usually die casting mold temperature control includes two aspects of heating and cooling.The die-casting mould multichannel intelligent temperature control method is studied by cooling water circulation,which uses fuzzy control to realize,aiming at solving the shortcomings of slow speed and big energy consumption during the cooling process of current die-casting mould.Die temperature control requirements for pressure casting are introduced in the first.Then the overall plan for die temperature control is designed according to the control demand of pressure casting.At last,simulate and analyze the output.The fuzzy controller design is improved for defects exiting in the mould temperature control by a simple two-dimensional fuzzy control and traditional PID control method.For more accurate and better control effect,a fuzzy parameter adjuster is added,which can adapt to changing circumstances and enable temperature to keep within a reasonable range in each period of time,realizing the precise control of mold temperature.Simulation results show that die-casting mold temperature control based on fuzzy control method is completely feasible which has higher control precision.
