Abstract
Description
Technical Field
[0001] The utility model relates to a modeling die for the plasticity of plasticine. Background Art
[0002] The quality and safety issues of student supplies have always attracted the attention of all sectors of society. Plasticine, commonly known as "plasticene", is usually used for children's labor, school teaching, model design, art modeling, etc. Among them, the plasticity index is an important index of plasticine, which directly affects the use effect of plasticine. Therefore, it is particularly important to obtain rapid and accurate test data.
[0003] In the standard QB / T 2960-2008 "Plasticine", the sample preparation for the plasticity of plasticine is involved. It is required that the size of the plasticine plasticity sample is a cylinder with a diameter of φ (28×38) mm. When in use, white oil is applied on the upper and lower pressing plates to make it have good anti-sticking performance. A sample block with a height greater than 40 mm, flat upper and lower surfaces, and a length and width greater than 40 mm, which is kneaded by hand, is placed on a stainless steel plate. The die is pressed vertically with force to make the mud completely fill the die. Then, the excess mud is cut off with a mud cutter, scraped flat with a scraper, and finally, a plastic cylinder with a diameter slightly smaller than the inner diameter of the die is used to gently push the sample out of the die. The size and uniformity of the prepared sample directly affect the accuracy of the plasticity test. Due to the lack of a special plasticity sample preparation device, the conventional demoulding method is to demould by applying oil, and direct hand contact is often used during demoulding. Therefore, problems such as smooth demoulding failure and deformation of the sample cylinder after demoulding often occur, thus affecting the accuracy of the subsequent plasticity test. In addition, since it is inconvenient to clean the die after sample preparation, the plasticine remaining on the die is also likely to cause the failure of the next sample preparation, and the long sample preparation time results in low work efficiency. Therefore, it is of great significance to develop a convenient-to-operate plasticine plasticity sample preparation device. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems existing in the lack of a special sample preparation device for the plasticity test of plasticine under the existing technical conditions, and to provide a new type of convenient-to-operate plasticine plasticity sample preparation die. The utility model designs a plasticine plasticity sample preparation die, including a central main shaft and a push-pull rod. The characteristics are as follows: a semi-cylindrical blade is fixedly connected to the front end of the push-pull rod, and a semi-cylindrical insert is arranged opposite to the semi-cylindrical blade. The cylinder formed by the semi-cylindrical blade and the semi-cylindrical insert at the front part of the push-pull rod is nested in the central main shaft. The semi-cylindrical insert is connected with a protruding tail. The cutting edge of the semi-cylindrical blade is arranged on the two straight edges of the semi-cylinder. The advantages of the utility model are: the push-pull rod is detachable, which is convenient for cleaning; the push-pull rod can rotate, and the front end is connected with a semi-cylindrical blade, so that the semi-cylindrical blade can rotate inside the central main shaft to separate the plasticine from the die, and the semi-cylindrical blade is pushed by the push-pull rod, which is convenient for demoulding, ensuring the uniformity of the test cylinder and thus reducing the influence on the subsequent plasticity test. At the same time, the sample preparation time is also greatly reduced, and the sample preparation efficiency is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The following specific embodiments further illustrate the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
[0010] In the figure, a plasticine plasticity sampling mold includes a central main shaft 1 and a push-pull rod 2. It is characterized in that: a semi-cylindrical blade 3 is fixedly connected to the front end of the push-pull rod, and a semi-cylindrical insert 4 is arranged opposite to the semi-cylindrical blade. The cylinder formed by the semi-cylindrical blade and the semi-cylindrical insert at the front part of the push-pull rod is nested in the central main shaft. The semi-cylindrical insert is connected with a protruding tail 5. The cutting edge 6 of the semi-cylindrical blade is arranged on two straight edges of the semi-cylinder.
[0011] The staff places a sample block manually kneaded to a height greater than 40 mm, with flat upper and lower surfaces and both length and width greater than 40 mm, on a stainless steel plate. Insert the semi-cylindrical insert and the push-pull rod 2 fixedly connected with the semi-cylindrical blade into the central main shaft 1. The protruding tail of the semi-cylindrical insert 4 faces the outside of the central main shaft 1, so that the semi-cylindrical insert 4 adheres to the inner wall of the central main shaft. After the semi-cylindrical insert 4 and the semi-cylindrical blade 3 are combined, they form a cylinder, and its size just fits into the central main shaft without sliding but not being overly tight. Press the assembled mold vertically downwards with force, so that the mud completely fills the cylinder formed by the combination of the semi-cylindrical insert 4 and the semi-cylindrical blade 3. Gently press the top of the cylinder of the push-pull rod 2 to compact the mud, then use a mud cutter to cut off the excess mud and scrape it flat with a scraper. Hold the protruding tail of the semi-cylindrical insert and gently pull out the semi-cylindrical insert 4 to create a gap between the central main shaft 1 and the mud. At this time, gently rotate the top of the cylinder of the push-pull rod 2 to drive the semi-cylindrical blade 3 to rotate in the gap, so that the mud is separated from the inner wall of the central main shaft 1. After complete separation, push the top of the cylinder of the push-pull rod 2 to drive the semi-cylindrical blade 3 to gently push out the loaded sample from the central main shaft 1.
[0012] Ensured the uniformity of the test cylinder, thus reducing the impact on subsequent plasticity tests. At the same time, it also greatly reduced the sample preparation time and increased the sample preparation efficiency.
