Design on controller of plastic injection-molding machine based on multi-CPU

Abstract

With the development of electronic technology, the plastic injection molding machine controller which applied a single CPU core in the low-end plastic injection molding machines cannot meet the need. In order to resolve the problems of the current plastic injection molding machine controller, which include big volume, low integration, complexity hardware, low reliability, low price-performance ratio, and unsatisfactory control effect, a high level of integrated fully automatic plastic injection molding machine controller which based on multi-CPU will be researched. Multi-CPU is used for hardware design. The adaptive intelligent control algorithm is applied on software design in order to achieve accurate temperature control. At the same time, the output circuit detection technology is used to make the perfect combination on hardware and software. Practice has proved that the new utility model have improved the reliability and the accuracy of the injection molding machine controller, and the controller have the benefits of high integrated of hardware system, simple structure, high performance-to-price ratio and so on.
