江苏省镇江远东耐酸泵厂是生产化工耐酸泵专业厂，需用大量的法兰盘式空心圆饼铸件。以前采用合金钢板，用气割办法下料，既浪费材料，生产效率又很低。如果采用砂箱造型铸造，工装、材料等生产条件又不具备。因此，采用木模制型芯片（图１），垂直组型（图２），实行顶浇。为 Zhenjiang, Jiangsu Province, Far East acid pump plant is the production of chemical acid-resistant pump professional factory, the need to use a large number of flange-shaped hollow pie casting. In the past the use of alloy steel, gas cut cutting method, not only waste materials, production efficiency is very low. If the use of sand box casting, tooling, materials and other production conditions do not have. Therefore, the use of wood mold chip (Figure 1), vertical type (Figure 2), the implementation of top pouring. for
