- 摘要:
- 随着树脂自硬砂的发展,传统组芯造型工艺在大型、复杂铸件生产中得到大量应用。采用三乙胺冷芯盒法的自动化精密组芯造型生产线已成功应用于汽车零件铸造,如整铸式铸铝冷凝换热器,发动机缸体、缸盖等尺寸精度要求高、工艺复杂的中小铸件的批量生产。综述了三乙胺冷芯盒法的精密组芯造型工艺的发展及其应用,该工艺是砂型铸造实现绿色化、智能化生产的重要途径之一。进一步提高原材料和设备的国产化率,强化生产中的环保措施,无机粘结剂及相关设备的研制与工艺开发是今后发展的方向。
With the development of self-hardening resin sand,the traditional core molding process had been widely used in the production of large and complex castings.The automatic precision core molding production line using triethylamine cold core box method had been successfully applied to automobile parts casting,such as the whole casting aluminum condensing heat exchanger,engine cylinder block,cylinder head and other size accuracy requirements,complex process of small and medium-sized casting batch production.The development and application of the precision core molding process of triethylamine cold core box method was reviewed.This process was one of the important ways to realize green and intelligent production of sand mold casting.Further the rate of domestic production of raw materials and equipment is improved,the environmental protection measures in production is strengthened,the development of inorganic binder and related equipment and process development is the future development direction.
