一九五四年美国 GE 公司用二面顶“年轮”式超高压模具首先研制成功了人造金刚石。我国于一九六三年也获得了成功。迄今,已有廿多年历史了。目前世界上许多国家在生产人造金刚石。关于生产人造金刚石的超高压模具,GE 公司已申请了专利,但是,至今仍严加保密。本文对我国从瑞典引进的1100T“年轮”式模具(据说是 GE 专利)进行了应力分析和计算。 In 1954, GE of the United States successfully developed man-made diamonds by means of the two-face top “annual wheel” UHV mold. Our country also succeeded in 1963. So far, more than 20 years of history. Many countries in the world currently produce synthetic diamond. GE Corp. has applied for a patent on UHMW-injection molds for artificial diamond, but it is still strictly confidential. In this paper, the stress analysis and calculation of 1100T “annual wheel” mold (which is said to be GE patent) imported from Sweden in our country were carried out.
