Abstract
Based on the analysis of lost foam casting mould forming process and discussed the forming process of copolymer beads by pre foaming after the configuration of the hardware components of mold pattern molding machine control system.The system used SIEMENS S7-200PLC as the control core and TD200 text display tools for setting parameters as well as the control system in software design combined the mold cavity injection, steam heating two foam, spray cooling and vacuum drying process engineering together to make lost foam casting molding process automation.At the same time it can be manually operated single procedure.Finally, the low molding density and low strength caused by the mold cavity temperature overheating were analyzed and discussed;the double solenoid valve temperature control loop regulation complementary was put forward.The results show that the molding control system based on PLC is effective in the practice of melt-molding, optimizing the investment casting mold and improving the yield.关键词
