大多數的机械化鑄造車間的實際工作證明,在很多情形中,矽模開箱脱砂的操作地位是最狹窄的;要在有限的地位中做起重和轉運数量很大的、沉重的砂箱和鑄件的工作,而且还要在溫度很高的狀态下进行操作。在鑄造生產操作程序中,開箱脱砂是一道最困難和最勞苦的工作。在最近數年來, The practical work of most mechanized foundries proves that, in many cases, the operational status of unmolded sand removal is the narrowest; to carry out heavy lifting and transfer of heavy, heavy sand boxes in a limited position. Work with castings, but also at high temperatures. In the casting production operation procedure, unpacking and sand removal is the most difficult and laborious work. In recent years,
