摘　　要：对纸浆模塑吸滤成型模具的吸浆孔结构进行了优化,以提高产品吸滤成型效率及均匀性。建立了纸浆模塑吸滤成型模具吸浆过程阻力的数学模型,通过分析该模型得出吸浆孔的孔径大小及入出口截面突变是影响吸浆过程压力损失的主要因素。利用ANSYS/FLOTRAN仿真分析软件,分别对不同孔径、不同锥度、不同倒角半径的模具吸浆孔模型进行了模拟分析,并通过对比分析得到了最优吸浆孔结构参数;最后进行了对比验证实验,确定了纸浆模塑模具吸浆孔结构的优化参数:孔径为3 mm,锥形吸浆孔的入口口径为3 mm,出口口径为5 mm,吸浆孔倒角半径为1.5 mm。The optimization research of suction filtration mold＇s midge pore structure of the pulp model was made to improve product suction filtration efficiency and uniformity. The resistance mathematical model of the process of suction filtration mold of pulp molding was established. Through the analysis of the model, it was concluded that the pore size of the slurry and the mutation of the inlet and outlet section were the main factors influencing the pressure loss in the slurry process. Then the simulation software ANSYS/FLOTRAN were applied to simulate and analyze grout hole models with different diameters, tapers and chamfer radius. At last, the experiment was carried out. The optimization parameters of pulp mold suction hole structure were determined as the pore size being 3 mm, tapered bore grout inlet diameter being 3 mm, outlet diameter being 5 mm, grout hole chamfer radius being 1.5 mm respectively.
