一种用于低压铸造铝合金车轮时减少缺陷的模具
摘要：
本发明提供一种用于低压铸造铝合金车轮时减少缺陷的模具，所述的模具包括顶模、边模和底模，所述的顶模设置在上方并且设置为完成车轮的背腔，底模设置在顶模的下方并且设置为完成车轮的正面轮盘造型，边模设置在顶模和底模的侧面，顶模、边模和底模共同围绕出铝合金车轮的铸造型腔；所述的底模的上表面包括用于形成轮辐的凹陷部分和用于形成窗口的凸台部分；所述的用于形成窗口的的凸台部分中包括冷却管道。本发明的模具使车轮铸件的热节缩松缺陷减少了40％，轮缘气孔问题降低了30％，大大的提高了成品率，降低了生产成本，保证了车轮的高质量生产。
摘要（英）：

A mold for reducing defects in low pressure casting of an aluminum alloy wheel includes a top mold, a side mold and a bottom mold, wherein the top mold is arranged above the bottom mold to mold a back cavity of a wheel, the bottom mold is arranged below the top mold to mold a front wheel disc of the wheel, the side mold is arranged on the side of the top mold and the bottom mold, and the top mold, the side mold and the bottom mold collectively surround a casting cavity of the aluminum alloy wheel, wherein the upper surface of the bottom mold includes a recessed portion configured to form a spoke and a boss portion configured to form a window and wherein the boss portion configured to form the window includes cooling ducts.
