影响压铸速度的因素及其理论分析

EFFECTIVE FACTOR OF THE RATE OF DIE CASTING AND THEORETICAL ANALYSIS

本文运用质量连续方程和伯努里方程,从动力特性和负载特性综合分析研究了蓄压器比压、压射活塞直径、冲头速度调节阀、压室直径、内浇口大小对压铸速度的影响,导出了压铸速度的数学表达式。从而得到蓄压器中的比压、压射力、压射冲头速度调节阀门开启程度、压室直径、内浇口大小对压铸速度的影响规律。

In this paper, with the help of the Equation of Continuity and the Bernoulli's Equation, the effect of the pressure in oil pressure accumulators, the diameter of injection piston, the regulating valve of the speed of injection plunger, the diameter of injection chamber and the size of ingate on the rate of die casting have been studied dynamically and systemically. A mathematical expression of the rate of die casting is deduced. Various effects on die casting speed have also been discussed.
