The invention discloses a manufacturing method of an aluminum alloy casting and an automobile anti-collision beam applying the aluminum alloy casting. The manufacturing method comprises the followingsteps of S1, preparing special-shaped closed-cell foamed aluminum, specifically, tackifying and stirring an aluminum melt, adding a foaming agent and stirring, injecting a foam body into a foam investment, preserving heat and foaming, and cooling the foam body to obtain the special-shaped closed-cell foamed aluminum; S2, pretreatment of the special-shaped closed-cell foamed aluminum, specifically,soaking the special-shaped closed-cell foamed aluminum with a NaOH solution, washing with clear water, drying and heating; S3, preparing an aluminum alloy melt; S4, treatment of a casting mold, specifically, heating the casting mold, removing dust, uniformly spraying a coating on the inner surface of the mold, heating and preserving heat; and S5, casting forming, specifically, putting the special-shaped closed-cell foamed aluminum obtained after the step S2 is completed into a preheated casting mold, mold assembly in place, setting preset casting technological parameters, casting, and finallyobtaining a needed casting.

    本发明公开了一种铝合金铸件的制造方法及应用该铝合金铸件的汽车防撞梁,包括以下步骤:S1.异形闭孔泡沫铝制备,工艺流程顺序包括:铝熔体增黏搅拌,添加发泡剂搅拌,将泡沫体注入泡沫熔模,保温发泡,泡沫体的冷却,异形闭孔泡沫铝;S2.异形闭孔泡沫铝预处理,包括:用NaOH溶液浸泡异形泡沫铝,之后用清水冲洗后将其烘干,加热;S3.铝合金熔体制备;S4.铸造模具处理:包括铸造模具加热,除尘,最后在模具内表面均匀喷涂料,加热保温;S5.铸造成形:将S2完成后的异形闭孔泡沫铝放入预热好的铸造模具中,模具合型到位,设定好预定铸造工艺参数,进行铸造,最后得到所需铸件。
