基于Moldex3D碳罐本体优化分析及模具设计

Optimization analysis of carbon canister based on Moldex3D and the mould design

新开发的ORVR活性碳罐本体由于结构特殊、尺寸较大,具有深腔结构,成型时易出现翘曲变形,影响塑件成型质量及实际使用功能,模具设计过程中存在一定的技术难点。运用Moldex3D模流分析软件对注射成型冷却系统及浇注系统进行优化分析,仿真结果显示X、Y、Z方向的翘曲变形量都有所减小,翘曲变形总量由4.762 mm减小到3.484 mm,再通过模具预变形设计达到装配要求。根据Moldex3D的优化分析结果,最终完成碳罐本体注射模设计。

In view of the special structure, large size and deep cavity structure of the newly developed ORVR charcoal canister, it was hard to design the injection mould. And the warpage and deformation of it were easily occurred which reduced the quality of the plas- tics and the practical use function of the carbon canister. So the Moldex3D moldflow analy- sis software was used to optimize and analyze the cooling and filling system of the mould. The results showed that the total warpage deformation in the X, Y and Z directions was re- duced from 4.762 mm to 3.484 mm, which was met the assembly requirements of the plas- tics by the pre-deformation for the mould. Finally the injection mould design of the car- bon canister was achieved according to the Moldex3D optimization analysis.
