- ProCAST software is used as sand mold casting simulation software to solve the interface heat transfer coefficient, but there are still some deviations in the setting of many physical parameters, which also has a certain impact on the simulation results. For example, the permeability of sand box and the influence of sand mold coating on the surface of sand mold castings in practical application are not considered. This requires continuous improvement of material physical parameters and boundary conditions, so as to obtain accurate solution results.
- Due to the influence of time and computer performance, only the temperature field of sand castings in the process of mold filling and solidification is simulated, and the stress analysis of sand castings is not carried out. In the follow-up, the mold design can be optimized through stress analysis.
- The mold structure is mostly designed according to traditional experience. For rapid sand casting, SLA is used to replace wood mold. Some structural designs do not consider the difficulty of workers’ operation and the actual production capacity of the factory. Later, it is necessary to modify the cooperation of some mold modules to achieve convenient and reliable operation.
