Z8612B热芯盒射芯机,由一六位手动转阀操作各部动作。由于是手动操纵,人为因素多,致使砂芯质量不稳定,废品率高。应用可编程序控制器(PC)对其进行电气控制技术改造,排除人为操作因素影响,确保工艺纪律的严格执行,砂芯质量稳定提高。
The actions of the parts in Z8612 Bhot box core shooter are operated by a 6-position hand operated revolving valve. Owing to it being operated manually and full of man-made effects, it results in unstable in core quality and high rejects, Technical renovation on the electric control has been carried out with the use of PC and the effects of man-made operation factors have been expelled. It ensures strict implementation of technological regulations and steady improvement of core quality.
