| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 102 === In Taiwan, the manufacturing industry is energetic and export-oriented mainly. There are many components produced by using die casting in the automotive and motorcycle. The die-casting machine is the one kind of equipments for producing the die-casting components, and its peripherals including ladle, sprayer, and extractor.
This paper studies the die-casting machine equips with a PC-Based computer used for monitoring purposes. PLC controls the die-casting machine and its peripherals’ motions, and PC-Based LabVIEW program controls the injection speed. PC-Based computer measures the servo valve’s response time in the injection hydraulic system, and monitor the displacement, speed, and pressures of the injection system. Comparing the results of the PLC-Based and PC-Based injection speed control shows the PC-Based control can maintain injection speed better. The man-machine interface and the measuring program are written by using LabVIEW Graphic Programming software. The injection mode is set as multi-stage speed.
