摘要

根据摩托车钳体零件的结构特点

在用AutoCAD软件设计出模具的二维平面图的基础上

以Pro/E所建立的三维实体模型为平台

用3D-MAX动画软件对模具进行了运动仿真

同时用铸造模拟软件JSCast对钳体成形过程中的流场和温度场进行了模拟。仿真和模拟与实际情况相符

在零件的圆转角厚大部位处出现缩孔。在对模拟结果进行比较后

通过在铸件厚大部位增设型芯的办法

实现了铸件壁厚的均匀分布

铸件的凝固过程得到了改善

消除了厚大部位的热节

提高了铸件的品质。

Abstract

Aiming at structural features of motorcycle brake clamp body

based on 2D model designed by the Auto CAD

visualization of the model was developed with the help of 3D-MAX software on established 3D model platform by Pro/E software

and flow field and temperature field in the parts during filling process were simulated by the JSCast software.The simulated results are well in agreement with the experimental ones

so potential defects and their position in the parts were predicted by the model

and processing design was examined by the JSCast software with the completion of optimized design.Solidification process was obviously improved as a result of uniform distribution of temperature field in wall thickness by setting core at thick position of the parts

eliminating the hot spot in thick position and improving the quality of the parts.
