一个合适的绿色砂型需要砂系统进行适当的管理。模拟是砂型造型设计和控制的有力工具，因此对造型模拟的需求也越来越大。在本研究中，挤压成型模拟进行考虑颗粒尺寸分布。结果，很明显，在挤压成型过程中的空隙率和压实压力之间的关系是明确的。还阐明了粒度分布对型砂层紧实行为的影响。此外，在本研究中显示了绿色砂造型的三维可视化。
A suitable green sand mold requires the sand system to be managed appropriately. Simulation is a useful tool for designing and controlling for the sand molding, so the demand for molding simulation is increasing. In the present study, the squeeze molding simulation is carried out considering the particle size distribution. As a result, it was clear that the relationship between the void fraction and the compacting pressure during squeeze molding was clarified. The influence of the particle size distribution on the compacting behavior of the molding sand layers was also clarified. Further, the three-dimensional visualization of the green sand molding was shown in the present study.
