型板造型是一种比較先进的造型方法。最近我們学习了苏联先进經驗,利用一块型板,分別做出上下箱砂型来,在上下箱砂型之間放一片泥心,將砂型分隔为兩层,鑄出双层鑄件。这种造型方法既节省作业面积,又能提高生产效率。我們將这种造型方法叫做双层多模造型法。这种型板和普通的單面型板相同,只不过在型板上多做出泥心头部分。型板的形狀如图1,型板上有泥心头部分,横澆口模,鑄件模
Stencil shape is a more advanced modeling methods. Recently, we learned the advanced experience of the Soviet Union, using a plate, respectively, to make sand boxes up and down, put a mud heart between the sand box, the sand is divided into two layers, cast double casting. This modeling method not only saves the work area, but also improves the production efficiency. We call this modeling method double-layer multi-mode modeling. This type of plate and the same single-sided plate the same, but more in the template made muddy heart. Form the shape of the board in Figure 1, the template has muddy heart part, horizontal gate mold, casting mold
