摘　　要：连杆作为空压机能量转换的主要运动部件,浇注温度对其成型质量有着重要影响。本文采用Anycasting软件数值模拟ZL114合金连杆充型凝固过程,研究了640℃、660℃、680℃、700℃、720℃浇注条件下,合金连杆的成型质量,结果表明,当浇注温度为640℃时,ZL114合金连杆的部分区域会形成缩孔缩松。而随着浇注温度的升高,连杆上的缺陷逐渐减少。当浇注温度为680℃时,连杆上的缺陷消失。而浇注温度从680℃~720℃,连杆上仍没有缺陷形成。ZL114合金连杆的浇注温度:680℃~720℃。As the main moving part of the energy conversion of the air compressor, the casting temperature has an important influence on the molding quality. This paper has studied the influence of casing temperature on the forming quality of the ZL114 alloy connecting rod by the Anycasting numerical simulation software during the filling solidification process;the results show that when the pouring temperature is 640?C, ZL114 alloy connecting rod parts of formation porosity shrink. With the increase of casting temperature, the defect on the connecting rod gradually decreases. When the pouring temperature is 680?C, the flaws of the connecting rod disappear. And while the pouring temperature ranges from 680?C to 720?C, there is still no defect on the connecting rod. The ZL114 alloy connecting rod pouring temperature ranges from 680?C to 720?C.
