Current entire industrial productionThe development characteristicis the product variety many,renews, the market competition quickly is intense. In order to adapt the market the short date of delivery which makes to the mold, highaccuracy, low costThe urgent need, the mold will have the following developmenttendency reached 2-3 mu m, soon 1 precision mold soon molds processing precisionrequest in 1 mu m, this request development superfinishing large-scale, on the other handalso is because the high productivity wants cavities) to be the resultof. The expansion applies the hot flow channel technology. Becauseuses the hot flow channel technology the mold to be possible to enhance the workpiece the production efficiency and the quality, and can large scale save development, manyplastics molds factory production mold above 50% uses domestic has also used into produce, some enterprises utilization ratio achieves 20% ~ 30% 参考资料 . 人民邮电出版社 始——UG中文板基础培训教程. 人民邮出版社 Unigraphics 注塑模具设计. 北京大学出版社 [10] 模具实用技术丛书编委会编. 塑料模具设计制造与应用实例. 机械工业出版社 |
