前 言 P—Q~2图表预测某些模具在某压铸机上生产时,可能获得的结果(即工作点的确定),事前采取必要措施,有的放矢,使模具的修改工作减少到最低限度,防止盲目性和少走弯路。通过该图表的推广应用,作者热切期望压铸机制造行业,当机床出厂时应向用户同时提供经过测试的P—Q~2图表,使用户有据可查。它将对我国压铸工业的技术水平起到积极的推动作用,这就是撰写本文的基本出发点。
Foreword The P-Q ~ 2 chart predicts the possible results (that is, the determination of the working point) of certain molds when they are produced on a die-casting machine and takes the necessary measures in advance to reduce the modification work of the molds to a minimum and prevent blindness And less detours. Through the popularization and application of the chart, the author is eagerly looking forward to the die-casting machine manufacturing industry. When the machine tool is shipped from the factory, the tested P-Q ~ 2 chart should be provided to the user at the same time so that the user is well documented. It will play a positive role in promoting the technical level of China’s die-casting industry, which is the basic starting point for writing this article.
