[0027] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0028] In the prior art, the cement specimen is usually separated from the mold by turning the mold upside down. During this process, the quality and appearance of the specimen are easily damaged, affecting the user experience, which is not conducive to the promotion and application of the above method in the field of cement production and testing technology.

[0029] In order to solve the above technical problems, Figures 1 to 6As shown, a test piece ejection device is used to eject the test piece in the adhesive film 3 to separate the adhesive film 3 from the test piece, and in this process, the adhesive film 3 does not need to be turned upside down to ensure the integrity of the test piece during the removal process. Specifically, the above-mentioned adhesive film 3 is mainly composed of an adhesive film base 3-1 and an upper mold 3-2. The above-mentioned upper mold 3-2 and the above-mentioned adhesive film base 3-1 can be detachably arranged in a detachable manner such as bolt connection, that is, before the test piece is ejected, the above-mentioned adhesive film base 3-1 is first detached, and then the upper mold 3-2 is placed on the above-mentioned test piece ejection device. Specifically, in order to ensure the use effect, the above-mentioned test piece ejection device in this embodiment includes an upper mold disassembly seat 1 and a test piece ejection mechanism 2. The above-mentioned upper mold disassembly seat 1 includes an upper mold sliding plate 1-1 and a support column 1-3. The upper mold sliding plate 1-1 is arranged in a flat plate shape, and in particular, the upper surface of the upper mold sliding plate 1-1 is arranged in a plane shape, in order to fit with the bottom surface of the upper mold 3-2 to ensure the stability and integrity of the test piece during the removal process. In order to ensure that the upper die sliding plate 1-1 has a certain height, so as to facilitate the installation of the test piece ejection mechanism 2 located below it, the support column 1-3 is installed below the upper die sliding plate 1-1 and used to support the upper die sliding plate 1-1, which can also effectively ensure the stability of the upper die sliding plate 1-1 during use. Specifically, a threaded hole can be started below the upper die sliding plate 1-1, a threaded section can be set at one end of the support column 1-3, and the support column 1-3 and the upper die sliding plate 1-1 can be detachably connected by threading the support column 1-3 and the upper die sliding plate 1-1. The specification model or height of the support column 1-3 can be adjusted according to actual needs, so that the upper die disassembly seat 1 can be used in different occasions, so that it has a wider range of applications. In order to realize the function of ejecting the specimen by the above-mentioned specimen ejection device to realize the separation of the upper mold 3-2 from the specimen, an ejection groove 1-2 is provided on the above-mentioned upper mold sliding plate 1-1. The shape and size of the ejection groove 1-2 can be adapted to the shape and size of the specimen. The main purpose is to realize the separation of the upper mold 3-2 from the specimen and ensure the integrity of the specimen. In this embodiment, the above-mentioned specimen ejection mechanism 2 includes an ejection cylinder 2-2 and an ejection push plate 2-3. The ejection cylinder 2-2 has high stability and strong practicality. By installing the above-mentioned ejection push plate 2-3 at the output end of the above-mentioned ejection cylinder 2-2, that is, by starting the ejection cylinder 2-2, and then pushing the ejection push plate 2-3, the above-mentioned ejection push plate 2-3 is arranged opposite to the ejection groove 1-2 to push out the specimen in the above-mentioned upper mold 3-2. The size and shape of the ejection push plate 2-3 are adapted to the size and shape of the ejection groove 1-2. Similarly. The purpose is to realize the separation of the upper mold 3-2 from the specimen and ensure the integrity of the specimen.

[0030] In order to ensure the stability of the ejection cylinder 2-2 during use and shorten the driving stroke of the ejection cylinder 2-2 to improve the use efficiency of the cylinder, a cylinder mounting seat 2-1 is installed at the bottom of the ejection cylinder 2-2 in this embodiment. The cylinder mounting seat 2-1 has a certain height and must ensure stability during installation and use. The cylinder mounting seat 2-1 in this embodiment is a channel steel structure, which ensures stability while ensuring its own structural strength, while saving manufacturing materials and reducing production costs.

[0031] Furthermore, in order to ensure the stability of the upper mold 3-2 during the process of pushing the test piece and reduce the probability of the upper mold 3-2 moving, in this embodiment, a positioning cylinder 2-4 is installed on the side of the ejection cylinder 2-2, and a positioning push plate 2-5 for positioning the side of the film 3 is installed at the output end of the positioning cylinder 2-4. Similarly, in order to shorten the driving stroke of the positioning cylinder 2-4, the positioning cylinder 2-4 is installed on the cylinder mounting seat 2-1, and the stability of the positioning cylinder 2-4 during installation and use is ensured. In order to facilitate the pushing of the positioning push plate 2-5 and then fix it on the side of the upper mold 3-2, the upper mold sliding plate 1-1 is adapted to have a push groove 1-4 for the pushing of the positioning push plate 2-5, and the size and shape of the push groove 1-4 are adapted to the push groove 1-4. In this embodiment, there is only one positioning cylinder 2-4. In order to ensure the stability of the upper mold 3-2, a positioning pin can be installed on the other side of the upper mold 3-2.

[0032] The ejection cylinder 2-2 and / or the positioning cylinder 2-4 in this embodiment are three-axis cylinders. Compared with multiple single-axis cylinders acting together, the three-axis cylinder can save space, especially in a limited working space, which is very beneficial for compact design. The use of a three-axis cylinder can reduce the complexity of installation and connection because only one component needs to be handled instead of multiple independent cylinders. Considering the versatility and benefits of the three-axis cylinder, it can usually be more cost-competitive, especially in applications that require multiple movements. More importantly, the three-axis cylinder is used in this embodiment, and the multi-point drive method can effectively ensure the stability of the ejection push plate 2-3 and the positioning push plate 2-5 during the driving process, reduce the probability of their tilt, and then the driving force of the cylinder can be evenly applied to the specimen, thereby ensuring the integrity of the specimen.

[0033] The upper mold 3-2 in this embodiment includes a front baffle 3-2-1, a rear baffle 3-2-2 and a side baffle 3-2-3. The two side baffles 3-2-3, the front baffle 3-2-1 and the rear baffle 3-2-2 are combined to form a specimen cavity 3-2-5 for placing the specimen. The specimen cavity 3-2-5 is adapted to the ejection push plate 2-3 so as to realize the ejection action of the ejection push plate 2-3. In order to facilitate the preparation of multiple specimens at one time, a middle partition 3-2-4 is provided in the upper mold 3-2, that is, a middle partition 3-2-4 is provided between the two side baffles 3-2-3. Specifically, a mounting groove can be provided in the front baffle 3-2-1 and the rear baffle 3-2-2 corresponding to the position of the middle partition 2-4, and the middle partition 3-2-4 is embedded in the mounting groove. The plurality of intermediate partitions 3-2-4 can separate the test mold into a plurality of specimen cavities 3-2-5, so that each specimen cavity 3-2-5 can be filled with cement mortar separately, which is convenient for preparing multiple specimens. The intermediate partition 3-2-4 can also effectively prevent the test mold from deforming when filling the cement mortar, ensuring that the size and shape of the prepared specimen are accurate. The setting of the intermediate partition 3-2-4 can also prepare multiple specimens at one time, improve the efficiency of preparing the specimens, and save time and cost. In actual use, the position of the intermediate partition 3-2-4 can be adjusted according to the size and shape of the specimen.

[0034] Due to the viscosity of cement mortar, the adhesive film 3 and the test piece may sometimes stick together, making it difficult to remove the test piece. The adhesive film 3 in this embodiment, i.e., the adhesive film base 3-1 and the upper mold 3-2, are usually made of metal or plastic. The metal test mold is usually made of cast iron or steel, has high wear resistance and stability, and is suitable for long-term use. The plastic test mold is usually made of polymer material, has good anti-sticking and formability, and is suitable for one-time or short-term use. The user can choose a suitable test mold according to the needs.

[0036] A specimen ejection device in the above embodiment has a simple and ingenious structure and high practicality. By setting an upper mold disassembly seat 1 and a specimen ejection mechanism 2, it is applied to the film 3 in which the film base 3-1 and the upper mold 3-2 are detachably arranged. After the upper mold 3-2 is separated from the film base 3-1, the upper mold 3-2 with the specimen is placed on the upper mold disassembly seat 1, and then the ejection cylinder 2-2 in the specimen ejection mechanism 2 drives the ejection push plate 2-3 upward, thereby pushing the specimen in the upper mold 3-2 to achieve separation of the specimen from the upper mold 3-2. Compared with the flipping and tipping in the prior art, it can ensure the integrity of the specimen during the separation process, thereby ensuring the quality of the specimen, and at the same time can improve the separation efficiency and enhance the user experience, which is conducive to the promotion and application of the above-mentioned specimen ejection device in the field of specimen separation technology, and is not only limited to the field of cement production and detection technology.
