混合造型是以泥型为主,适当配合湿砂、水玻璃砂、干砂芯、以及水泥型、铁板、地坑等,综合了各种造型材料及工艺方法的优点,作成一个完整的铸型招来铸造大件及复杂件,以达到提高产量,保证质量的目的。是目前大型铸件和产量翻番一种有效的技术措施,是今后造型工艺的一个重要发展方向。 Mixed modeling is mainly mud-type, with the appropriate wet sand, sodium silicate sand, dry sand core, and cement type, iron, pit and so on, a variety of modeling materials and the advantages of the process, to create a complete cast Type cast casting large and complex parts, in order to achieve the purpose of improving production, quality assurance. It is an effective technical measure to double large castings and output at present and is an important development direction of modeling technology in the future.
