Description

Technical Field

[0001] The utility model relates to a metallographic embedding machine capable of avoiding sample splashing. Background Art

[0002] Hot embedding is a widely used metallographic sample preparation technology at present, which is convenient for preparing samples of irregular and small specimens. The embedding cavities of the prior art are all of an integral structure. During the embedding process, the embedding powder heated to the molten state is solidified under the action of the upper pressing die device. After the embedding is completed, the embedded sample is ejected by the lower die lifting device. Since the sample is tightly combined with the inner wall of the cavity, during the ejection process, affected by the demolding inertia force, the high-temperature sample will fly out quickly, which is likely to cause splashing injury and high-temperature scalding, presenting a huge potential safety hazard. If the sample is taken out after cooling, not only will the embedding efficiency be severely reduced, resulting in waste of waste heat, but also splashing injury will be caused. Therefore, it is urgent to change the sampling method of the embedding machine to make the embedded sample safer and more efficient. Summary of the Invention
