Abstract

本实用新型公开了一种铸造模具锁紧装置,包括凸起(1)、凹槽(2)、圆环(3),模具边模设置凸起(1),顶模设置凹槽(2),边模凸起(1)和顶模凹槽(2)相配合,边模外轮廓设置为圆形,边模外设置圆环(3)。与模具配合的动模板设置下推缸,所述下推气缸设置3台。本实用新型具有成本低,锁紧可靠,不能发生锁紧失效的优点。

Description

铸造模具锁紧装置
技术领域
本实用新型涉及模具,具体地说涉及中高压铸造模具。 
背景技术
铸造过程中提高保压压力会提高铸件的内在质量,但是存在“增大保温炉的耐压又增大主机的刚度及液压缸的锁紧力”难题,现有技术缺乏对该问题的解决方案。本实用新型是提供了一种适用中压铸造保压压力大大提高而又不改变低压铸造机的刚度及液压系统的一种锁紧装置。 
发明内容
本实用新型的技术方案为:本实用新型包括凸起、凹槽、圆环。铸造模具边模设置凸起,顶模设置凹槽,边模凸起和顶模凹槽相配合。边模外轮廓设置为圆形,边模外设置圆环。 
与模具配合的动模板设置下推气缸,下推气缸将所述圆环推至边模中部。所述下推气缸设置3台。 
本实用新型具有成本低,锁紧可靠,不能发生锁紧失效的优点。 
附图说明
图1是本实用新型铸造模具锁紧装置的结构示意图。 
图2是本实用新型铸造模具锁紧装置的结构示意图。 
图中:1-凸起,2-凹槽,3-圆环。 
具体实施方法
  如图1所示,本实用新型铸造模具锁紧装置包括凸起1、凹槽2、圆环3。模具边模设置凸起1,顶模设置凹槽2,边模凸起1和顶模凹槽2相配合。边模外轮廓设置为圆形,边模外设置圆环3。
与模具配合的动模板设置下推缸,下推缸将所述圆环3推至边模中部。所述下推气缸设置3台。 

Claims (2)
