手工活脱砂箱造型通常采用埋箱法,也就是砂型造好后放在砂地平面上,取去砂箱,在砂型四周埋砂,以增加砂型的强度,使它能够承受铁水的压力,如图1。这种方法最大的缺点是单位造型面积利用率低。针对这个情况,我们车间的工人同志们经过一番研究,在铸造小型铸件时,成功地应用了堆箱脱箱造型,使单位造型面积的利用率提高了1～1.5倍。这种方法的主要特点是:造好了的砂型被推到互相
Manual live sand box modeling commonly used in-box method, that is, after the sand made good sand on the plane, remove the sand box, burial sand around the sand to increase the strength of the sand to make it able to withstand the pressure of molten iron, as shown in Figure 1. The biggest drawback of this method is the unit shape area utilization is low. In response to this situation, our workshop workers comrades after some research, in the casting of small castings, the successful application of the stacker box shape, so that unit shape area utilization increased by 1 to 1.5 times. The main features of this method are: The well-made sand is pushed to each other
