摘要
电控永磁系统的基本工作原理就是利用不同永磁材料的不同特性,通过电控系统,对内部磁路的分布进行控制与转换,使永磁磁场在系统内部自身平衡,对外表征为消磁,即模具放松状态;或释放到吸盘工作表面,对外表征为充磁,即模具夹紧状态。为此设计了注塑机专用吸盘及自控系统。通过使用电控永磁快速换模系统,就能在1台注塑机上对各种不同模具进行快速换模,起到投资回报快捷、安装轻松容易的效果。
The basic principle of the permanent magnetic system is to use the different permanent material＇ s character to realize the control and conversion of the internal magnetic circuit distribution through electric control system . The balance of the magnetic system includes two stages , mag and demag. Mag means that the mould will be clamped into the plate and demag means that the mould will be released. Hence, we can easily change the different moulds in the same plastic machine with electric control permanentic quick mould changing system . As a result, the lower cost and easy maintenance are obtained.
