摘要

与手工模具相比

采用三维CAD/CAM技术

缩短了模具制造周期

泡沫模样更符合设计意图

不规则曲面、圆角处均能保证壁厚均匀

从而减少泡沫模样在后续浇注中产生的变形

铸件力学性能得到成功提高。完成18686-C型变速箱发泡模具的设计制造

模具达到设计要求

实现铸件批量生产。

Abstract

Compared with hand-made mould

using three dimensional CAD/CAM software

not only the manufacturing period of mould can be shortened but also the foamed pattern can fully meet the design ideal

in which the irregular curve face and fillet as well as uniform walled-thickness can be assured so that the pattern deformation can be restricted in subsequently pouring process to improve the mechanical properties of the components.The design and manufacturing of foamed pattern for 18686-C type gear box in lost foam casting were completed.It was verified that the pattern can fully meet the design requirement

realizing the batches of production.
