落砂机 利用振动和冲击(见机械振动)使铸型中的型砂和铸件分离的铸造设备。落砂机的振动源分为机械、电磁和气动3类,以机械的惯性落砂机应用较为广泛(见图)。惯性落砂机的结构特点是:落砂栅床装有带偏重的旋转轴,当轴旋转时偏重产生离心力(激振力),使安装在支撑弹簧上的落砂栅床振动,这种振动是由自由振动和强迫振动叠加起来的运动,载荷大小能使振幅发生变化。载荷过大,振幅急剧减小,落砂效率降低;载荷过小,振动太大,损坏砂箱和设备。为此在这类落砂机上面要加装固定支架,构成惯性冲击式落砂机。落砂时,铸型放在支架上,铸型底面和落砂栅床留有间隙,通过栅床振动撞击铸型底面,使铸件和型砂分离。由于铸型不是直接放在落砂栅床上,铸型重量的变化对落砂机振幅的影响相对地减小了。对于无箱铸型的中小型铸件,还可采用滚筒式落砂机,一般都安装在中小型铸件无箱造型生产线上,除落砂外,兼有热砂冷却、旧砂筛分、隔声隔热和除尘等作用。
