Local flexible structure of thin-wall complex deep drawing stamping part male die

The invention relates to a local flexible structure of a thin-wall complex deep drawing stamping part male die. The die has the functions of locally drawing a stamping material in advance and preventing a deep drawing part from being cracked. The mold is suitable for local structures of thin-wall complex deep-drawing stamping part molds, and is particularly suitable for local structures of shell stamping part molds such as automobile silencing bags and half shells; the specific structure is composed of a local window 18 of a male die 4, a deep drawing movable die block 6, a supporting block 8 and a spring 13. 本发明涉及的是一种薄壁复杂深拉伸冲压件凸模的局部柔性结构，模具具有在局部提前拉伸冲压材料，避免深拉伸部位出现拉裂状况的功能；适合薄壁复杂深拉伸冲压件模具的局部结构，特别适合汽车消声包、半壳等壳体类冲压件模具的局部结构；具体结构是由凸模4的局部窗口18、深拉伸活动模具块6、支撑块8和弹簧13部分组成。
