Description

Technical Field

[0001] The utility model relates to the field of electronic adhesive configuration and testing, in particular to a mold for making a high-elasticity, low-strength TMA sample block. Background Art

[0002] In industry, some parts need to be bonded with adhesives. In order to test and evaluate the performance of these adhesives, laboratories need to make specific test specimens. The Tg value of the adhesive is a very important indicator. The laboratory can use the TMA test method to test the Tg value of the adhesive. When the laboratory makes TMA specimens, it needs to ensure the flatness of the surface of the specimen to ensure the accuracy and repeatability of the test data. When the laboratory prepares TMA specimens of adhesives, it is generally operated manually, and the specimen is hit with a hammer to make the specimen fall off the specimen plate to complete the sampling process. Because many specimens have a low glass transition temperature and have the characteristics of high elasticity and low strength at room temperature, the overall strength of their TMA specimens is low, the surface hardness is low, and they are easy to scratch and cannot withstand impact. At the same time, the adhesive has a strong adhesion to the specimen plate, and sampling from the specimen plate faces difficulties. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a mold which is reasonably designed, convenient and quick and is used for making high-elasticity and low-strength TMA sample blocks in view of the deficiencies of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A mold for making a high-elasticity, low-strength TMA sample block, characterized in that the mold includes a sample block plate and a sampling plate, the sample block plate is provided with a plurality of sampling holes, the sampling plate is provided with sampling columns that cooperate with the sampling holes to eject the sample block from the sampling holes, and a pressure mechanism that provides continuous pressure to the sampling plate is provided in the middle position between the sample block plate and the sampling plate.

[0006] The technical problem to be solved by the utility model can also be achieved through the following technical scheme. The pressure mechanism includes a pressure screw and corresponding threaded holes arranged on the sample plate and the sampling block. The pressure screw cooperates with the threaded hole, and a gasket is installed at the threaded hole.

[0007] The technical problem to be solved by the utility model can also be achieved through the following technical solution: the sample preparation holes are arranged in two rows, and the pressure mechanism is arranged between the two rows of sample preparation holes.

[0008] The technical problem to be solved by the utility model can also be achieved through the following technical solution: two pressure mechanisms are provided, which are arranged side by side with the sample preparation holes.

[0009] The technical problem to be solved by the utility model can also be achieved through the following technical solution: the height of the sampling column is greater than or equal to the depth of the sample preparation hole.

[0010] Compared with the prior art, the utility model provides two parts, namely, a sample plate and a sampling plate. With the cooperation of a sampling column and a sample preparation hole, the impact force is converted into a continuous pressure. The contact part between the mold and the sample block remains fixed relative to the sample block, thereby preventing the surface of the sample block from being scratched or damaged. By designing threads at the corresponding positions of the sampling plate and the sample plate, and tightening the pressure screws on both sides in sequence, the sampling column in direct contact with the TMA sample block forms a continuous pressure on the sample block to be sampled, and finally the sampling column pushes the sample block out of the sample plate.
