陶瓷型铸造锻模工艺一般采用水玻璃砂衬石英陶瓷成型法,其铸造锻模精度不高,质量也不易控制。现改用塑料模,金属冷衬芯、金刚砂陶瓷型新工艺,来浇注翻斗车转向节锻模(材质为ZG5CrMnMo,尺寸330×270×150毫米,重约100公斤),造型工艺见图1。实践证明,该工艺成本低、上马快、模件质量好、寿命高。 Ceramic casting forging process generally use water glass sand lining quartz ceramic molding method, the casting forging accuracy is not high, the quality is not easy to control. Now use plastic mold, metal cold lining core, emery ceramic new technology, to pour dumper car steering knuckle die (material for the ZG5CrMnMo, size 330 × 270 × 150 mm, weighing about 100 kg), the molding process shown in Figure 1. Practice has proved that the process of low cost, quick start, good quality of the module, high life expectancy.
