Abstract

本实用新型涉及一种汽车悬架后副车架外板成型模具,包括上模、下模和顶料器,且在顶料器两端的突前支脚处设有凹槽,在模具的上模上设有与凹槽相对应的凸台。在成型模具上对应部位增设凸台和凹槽,增加的凸台和凹槽所吸收的一部分材料,而在成型过程中,在后序拉延时能补充到因为延伸率不够而导致的局部开裂的区域,从而解决了汽车悬架后副车架外板在拉延时局部开裂的问题。

Description

汽车悬架后副车架外板成型模具 
技术领域
本实用新型涉及一种汽车悬架后副车架外板成型模具。 
背景技术
汽车悬架是汽车上的重要部件,而后副车架则是连接左右纵臂的横梁,是整个扭转梁拖拽臂后悬架的主体。目前的后副车架外板在成型的后序拉延的过程中会由于延伸率不够而导致发生局部开裂的现象。 
发明内容
本实用新型针对后副车架外板在成型后序拉延的过程中局部开裂处,设计了一种能有效解决局部开裂的问题的汽车悬架后副车架外板成型模具。 
本实用新型的汽车悬架后副车架外板成型模具,包括上模、下模和顶料器,且在顶料器两端的突前支脚处设有凹槽,在模具的上模上设有与凹槽相对应的凸台。 
在拉延工序遇到类似局部开裂的情况时,根据拉延开裂的部位和开裂程度,在成型模具上对应部位增设凸台和凹槽,增加的凸台和凹槽所吸收的一部分材料,而在成型过程中,在后序拉延时能补充到因为延伸率不够而导致的局部开裂的区域,从而解决了局部开裂的问题。 
附图说明
图1为本实用新型的分散结构示意图; 
图2为图1脱除上模后的俯视结构示意图; 
图3为图2中A-A剖视图; 
图4为图2中B-B剖视图。 
具体实施方式
如图1-4所示,本实用新型的汽车悬架后副车架外板成型模具,包括上模1、下模2和顶料器3,且在顶料器3两端的突前支脚处设有凹槽4,在模具的上模1上设有与凹槽4相对应的凸台5。 
图2中a、b、c、d四个突前支脚为后序拉延的过程中容易开裂区域,针对a、b、c、d四处易开裂情况,在模具的顶料器3上开设凹槽4,在模具的上模1对应位置增设凸台5,增加的凸台和凹槽比较容易吸收一部分材料,在成型过程中,在后序拉延时补充到因为延伸率不够而导致局部开裂的区域,从而解决局部开裂问题。
