Transmission electron microscope sample preparation die and transmission electron microscope sample preparation sheet-punching machine

The invention provides a transmission electron microscope sample preparation die. The transmission electron microscope sample preparation die comprises an upper die assembly and a lower die assembly.The upper die assembly comprises a connecting seat and an upper die seat fixed to the lower part of the connecting seat. A punch needle is fixed to the lower part of the upper die seat. The lower dieassembly comprises a fixed table and a lower die seat fixed to the fixed table. A punching hole matched with the punch needle is formed in the lower die seat. An unloading rod structure capable of stretching up and down is arranged in the punching hole. The sample preparation die and the sheet-punching machine not only are simple in structure, but also can achieve automatic unloading, and are highin work efficiency. 本发明提供一种透射电镜制样模具，包括上模组件和下模组件，所述上模组件包括连接座和固定于连接座下部的上模座，所述上模座下部固定有冲针，所述下模组件包括固定台和固定于固定台上的下模座，所述下模座上设置有与所述冲针配合设置的冲料孔，所述冲料孔内设置有可上下伸缩的卸料杆结构。本发明提供的制样模具及冲片机不仅结构简单，且可以实现自动卸料，工作效率高。
