The utility model belongs to the technical field of vacuum mechanisms, and particularly relates to a die vacuumizing mechanism which is characterized in that a display panel is embedded in the top of the side wall of a shell, a turning cover is embedded in the bottom of the side wall of the shell, and the top of the shell is fixedly connected with a main mounting bottom plate through screws; the top of the main mounting bottom plate is fixedly connected with an oil-free rotary-vane vacuum pump and an auxiliary mounting bottom plate through bolts, and the output end of the oil-free rotary-vane vacuum pump is in threaded connection with an external flange. And the oil-free rotary-vane vacuum pump is connected with the vacuum valve assembly to form a combined vacuum mechanism, so that the stability is high, and modular vacuum treatment can be effectively realized. 本实用新型公开的属于真空机构技术领域，具体为一种模具抽真空机构，所述外壳的侧壁顶部镶嵌有显示板，所述外壳的侧壁底部镶嵌有翻盖,所述外壳的顶部通过螺丝固定连接所述主安装底板，所述主安装底板的顶部通过螺栓固定连接有无油旋片式真空泵和副安装底板，所述无油旋片式真空泵的输出端螺纹连接有外接法兰，该种模具抽真
