Influence of silicone rubber core mold hole occupancy ratio on dimensional shape force transfer effect and wall panel molding quality for co-curing of hat-shaped reinforced wall panels
摘要
Abstract
To meet the hat-shaped reinforced wall panel co-molding process of curing pressure uniform trans-mission,to achieve good thickness uniformity and cavity height of the parts,the hat-shaped reinforced wall plate molding process auxiliary core mold to improve,put forward a set of trapezoidal prefabricated holes in the silicone rubber thin-walled core mold-vacuum bag combination of new flexible core mold.Using the finite element simula-tion method,the effects of silicone rubber thin-walled core molds with different hole occupancy ratios on the uni-formity of pressure transfer during the co-curing molding process of hat-shaped reinforced wall panels were investi-gated,and the molding accuracy of hat-shaped reinforced wall panels after curing was analyzed.The results show that:when the silicone rubber thin-wall core mold prefabricated holes in the proportion of holes between 0.68～0.84,the silicone rubber thin-wall core mold expansion is moderate and uniform,can realize the uniformity and stability of the pressure transfer,and at the same time to ensure that the hat-shaped reinforced wall plate shape ac-curacy.Finally,the correctness of the finite element simulation of the thermal expansion of the silicone rubber core mold was verified by experimental methods,which created a process window for achieving the uniformity of the thickness of the silicone rubber core mold-assisted hat-shaped reinforced wall plate molding.关键词
