The invention provides an optimization design method for a casting process of a flame stabilizer. The optimization design method comprises the steps: obtaining thermophysical parameters of a flame stabilizer material through thermodynamic calculation; establishing a finite element calculation model of the flame stabilizer, wherein the thermophysical parameters serve as boundary conditions of the finite element calculation model; establishing a response surface model of the casting process parameters of the flame stabilizer; and performing process optimization on the established response surface model by adopting a genetic algorithm. A final performance test shows that through optimal design of process parameters, the final part is uniform in wall thickness, the shrinkage porosity of a shrinkage cavity is obviously improved, the grain size is uniform, the grain size of each section is moderate, and the performance index is greatly improved compared with that of the same model. 本发明提供一种火焰稳定器铸造工艺优化设计方法，包括：通过热力学计算
