Description

Technical Field

[0001] The utility model relates to the technical field of detection and analysis, in particular to a chamfer-free silicone cold mounting mold. Background Art

[0002] The use of embedding materials (such as epoxy resin, curing agent, etc.) to prepare powdered or block samples into reflective light sheets of specific specifications for analysis by instruments such as light microscopes and electron microscopes is one of the basic means of studying the basic properties of materials, and is widely used in research fields such as metallurgy and mineralogy. Reflective light sheets are generally ground manually or with a semi-automatic grinder and polisher. During the grinding process, the edges of the samples are relatively sharp, and it is easy to leave irregular scratches of varying depths on sandpaper and polishing cloths, resulting in scratches on the sample observation surface that are difficult to remove, affecting the sample observation effect and image quality. At the same time, it will also lead to an increase in the loss rate of grinding consumables and an accelerated loss rate, resulting in an increase in the cost of sample preparation. To solve this problem, the sample observation surface is generally chamfered before the sample is formally ground, that is, a grinding disc is used to manually grind off part of the edge of the observation surface to make it rounded for subsequent grinding. While manual chamfering can remove sharp edges from samples, it can also introduce other problems. For example, the inability to control chamfer accuracy can lead to over-chamfering of sample edges, compromising sample observation and subsequent positioning of the electron microscope stage. Furthermore, manual chamfering with improper force or positioning can injure the sample preparer and cause unnecessary safety incidents. Therefore, a chamfer-free mold is needed that can safely and effectively address the chamfering issues of reflective light sheets from the source. Utility Model Content
