Description

Technical Field

[0001] This utility model relates to the field of molding device technology, specifically a detachable concrete trial mixing and rapid molding device. Background Technology

[0002] After concrete is processed, its performance often needs to be tested. Testing concrete performance requires molding the concrete, which requires the use of a concrete sample rapid molding device to mold the concrete into blocks for later performance testing. The concrete sample rapid molding device is a device specifically designed to quickly and integrally mold concrete slurry into solid concrete test blocks for testing and evaluation of concrete performance.

[0003] Patent document CN208100669U discloses an electrically powered molding device for permeable concrete specimens. It discloses a device comprising: a concrete mold for holding permeable concrete, a base plate for mounting the concrete mold, a pressure plate for applying pressure to the concrete mold, a pressure rod for driving the pressure plate downwards, and an electric device for driving the pressure rod up and down, as well as a frame. The frame includes multiple columns fixed to the base plate, a support plate above the base plate, and a top plate above the support plate. The columns pass through the support plate from bottom to top and connect to the top plate. The electric device is located between the support plate and the top plate. The pressure rod is a threaded rod, and the support plate has threaded holes for threaded engagement with the pressure rod. The pressure plate is located at the lower end of the pressure rod. This molding device has a simple structure and is easy to use. It can effectively apply static pressure to the permeable concrete in the concrete mold, thereby avoiding problems such as slurry blockage and poor permeability caused by vibration molding of permeable concrete specimens.

[0004] However, the electric permeable concrete specimen molding device in the aforementioned published literature mainly considers avoiding the problems of slurry blockage and poor permeability caused by vibration molding of permeable concrete specimens, and the problem of inconvenience in disassembling the molding mold.

[0005] In view of this, it is necessary to develop a disassembly mechanism so that the molding die can be easily disassembled for material discharge. Utility Model Content

[0006] The purpose of this invention is to provide a detachable concrete trial mixing and rapid prototyping device to solve the technical problem mentioned in the background art of enabling the concrete trial mixing and rapid prototyping device to have a detachable function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable concrete trial mixing and rapid molding device, comprising: a base plate, a top plate and a molding mold, wherein the top of the base plate is provided with a disassembly mechanism, which is used to facilitate the disassembly of the molding mold for easy material discharge;

[0008] The disassembly mechanism includes a first positioning plate and a second movable plate. The first positioning plate is located on top of the base plate. The inner wall of the molding die is provided with an anti-stick coating. The top of the base plate is provided with a sliding groove. A sliding rod is installed on the inner wall of the sliding groove. A slider is installed around the outer wall of the sliding rod. The second movable plate is located on top of the slider. An adsorption magnet is installed on the outer wall of the second movable plate. A locking plate is provided on the outer wall of the second movable plate. A locking screw groove is provided on the top of the sliding rod. A locking screw is installed on the top of the locking plate, and one end of the locking screw extends into the interior of the locking screw groove.

[0009] Preferably, a support rod is installed on the top of the base plate, the top plate is located on top of the support rod, an electric telescopic rod is installed on the top of the top plate, a forming plate is installed at the output end of the electric telescopic rod, and a forming block is installed at the bottom of the forming plate.

[0010] Preferably, the outer wall of the molding block is provided with a drying mechanism, which is used to quickly dry and shape the concrete after pressing.

[0011] Preferably, the drying mechanism includes a drying fan, a sealing plate, and a wear-resistant layer, and the outer wall of the molded block is provided with a drying groove.

[0012] Preferably, the inner wall of the drying trough is equipped with a drying fan, the outer wall of the forming plate is provided with ventilation holes, and one end of the ventilation holes extends into the interior of the drying trough.

[0013] Preferably, the inner wall of the drying trough is equipped with a protective net.

[0014] Preferably, the outer wall of the molded block is provided with a rotating screw groove, the inner wall of the rotating screw groove is provided with a rotating screw, the bottom of the rotating screw is provided with a sealing plate, and the bottom of the sealing plate is provided with a wear-resistant layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a disassembly mechanism that facilitates the disassembly of the molding mold for easy material discharge. Most existing molding molds are fixed, making disassembly difficult. Therefore, a design that allows for easy disassembly of the molding mold and convenient discharge of the molded concrete test blocks is needed. First, during installation, one side of the molding mold is aligned with the outer wall of the first positioning plate. Then, the second moving plate is pushed, causing the slider to move on the sliding rod, attracting the magnet to the other side of the molding mold and initially positioning the second moving plate. Next, the locking screw is fixed into the locking screw groove, thus fixing the position of the locking plate and the second moving plate, thereby securing the molding mold between the first positioning plate and the second moving plate. Disassembly is performed by reversing the process. Furthermore, during disassembly, the anti-stick coating inside the molding mold prevents the concrete from adhering to the inner wall, facilitating disassembly and separation of the molding mold from the internal concrete test blocks for easy material discharge.

[0017] 2. This utility model, by installing a drying mechanism, allows concrete to be quickly dried and molded after pressing. Existing concrete test blocks require natural air to dry and solidify, resulting in low drying efficiency. Therefore, this needs to be improved. When the molded block comes into contact with the concrete, rotating the sealing plate causes the rotating screw to rotate clockwise and be fixed in the rotating screw groove. This seals the drying groove, allowing the wear-resistant layer to directly contact the concrete. When drying is required, the distance between the molded block and the mold is moved so that the molded block is above the mold. Then, the sealing plate is removed, and the drying fan blows air, causing airflow around the mold, thus accelerating the molding rate of the concrete test block in the mold.

[0026] Please see Figure 1 and Figure 2A detachable concrete sample preparation and rapid molding device includes: a base plate 1, a top plate 3, and a molding mold 7. A support rod 2 is installed on the top of the base plate 1, and the top plate 3 is located on top of the support rod 2. An electric telescopic rod 4 is installed on the top of the top plate 3. A molding plate 5 is installed at the output end of the electric telescopic rod 4, and a molding block 6 is installed at the bottom of the molding plate 5. The support rod 2 is provided in four sets. The electric telescopic rod 4 is a DT50 telescopic rod model. The molding block 6 and the molding mold 7 are both made of corrosion-resistant iron material. The molding mold 7 is a rectangular frame with a hollow center. The number of molding blocks 6 matches the number of molding molds 7, and the molding blocks 6 are located above the molding mold 7. The size of the molding blocks 6 matches the size of the hollow opening of the molding mold 7. First, concrete is added to the molding mold 7. Then, the electric telescopic rod 4 works to move the molding blocks 6, squeezing the concrete in the molding mold 7 to eliminate air bubbles. Then, it is left to stand for a period of time to allow the concrete to fully solidify, thereby molding the concrete sample block.

[0027] Please see Figure 2 and Figure 3The top of the base plate 1 is provided with a disassembly mechanism for easy disassembly of the molding mold 7 for material discharge. The disassembly mechanism includes a first positioning plate 9 and a second moving plate 13. The first positioning plate 9 is located on the top of the base plate 1. The inner wall of the molding mold 7 is provided with an anti-stick coating 8. The top of the base plate 1 is provided with a slide groove 10. A slide rod 11 is installed on the inner wall of the slide groove 10. A slider 12 is installed around the outer wall of the slide rod 11. The second moving plate 13 is located on top of the slider 12. An adsorption magnet 14 is installed on the outer wall of the second moving plate 13. The outer wall of the movable plate 13 is provided with a locking plate 15, the top of the slide rod 11 is provided with a locking screw groove 16, the top of the locking plate 15 is equipped with a locking screw 17, and one end of the locking screw 17 extends into the interior of the locking screw groove 16. A set of the first positioning plate 9 and the second movable plate 13 are provided (one set on each side of each molding die 7). The anti-stick coating 8 is a polytetrafluoroethylene coating. The slide groove 10 is located below the second movable plate 13, is provided in one set, and is a rectangular groove. A set of the locking screw groove 16 is provided, and is a circular screw groove. The locking screw 17 matches the locking screw groove 16. Most existing molding molds 7 are fixedly installed, making them difficult to disassemble. Therefore, it is necessary to make the molding mold 7 easy to disassemble and facilitate the discharge of the molded concrete test block. First, when installing the molding mold 7, one side of the molding mold 7 is made to fit against the outer wall of the first positioning plate 9. Then, the second moving plate 13 is pushed, and the slider 12 moves on the sliding rod 11, so that the adsorption magnet 14 is adsorbed to the other side of the molding mold 7, and the second moving plate 13 is initially positioned. Then, the locking screw 17 is fixed into the locking screw groove 16, which fixes the position of the locking plate 15 and the position of the second moving plate 13. The molding mold 7 is then fixed between the first positioning plate 9 and the second moving plate 13. Disassembly is the reverse process. During disassembly, the anti-stick coating 8 inside the molding mold 7 prevents the concrete from adsorbing to the inner wall of the molding mold 7, making it easy to disassemble the molding mold 7 and separate the molding mold 7 from the concrete test block inside, facilitating the discharge of the material.

[0028] Please see Figure 2 and Figure 4The outer wall of the molding block 6 is equipped with a drying mechanism, which is used to quickly dry and shape the concrete after pressing. The drying mechanism includes a drying fan 20, a sealing plate 24, and a wear-resistant layer 25. The outer wall of the molding block 6 is equipped with a drying groove 18, and the inner wall of the drying groove 18 is equipped with a drying fan 20. The outer wall of the molding plate 5 is equipped with a vent hole 19, and one end of the vent hole 19 extends into the interior of the drying groove 18. The inner wall of the drying groove 18 is equipped with a protective net 21. The outer wall of the molding block 6 is equipped with a rotating screw groove 22. A rotating screw 23 is installed on the inner wall of the trough 22. A sealing plate 24 is installed at the bottom of the rotating screw 23. A wear-resistant layer 25 is installed at the bottom of the sealing plate 24. The air-drying trough 18 is a rectangular trough, and the vent holes 19 are circular troughs. Each set of molding blocks 6 is provided with two sets of vent holes 19, and the inner wall of each vent hole 19 is provided with an air filter. The material and pore size of the air filter are selected according to the actual situation. There are three sets of air-drying fans 20 in a single air-drying trough 18, and the air-drying fans 20 are DF1203. The 8-type miniature fan has a stainless steel mesh protective net 21. Rotating screw grooves 22 and rotating screws 23 are matched. Each molding block 6 has one set of rotating screw grooves 22. The wear-resistant layer 25 is attached to the sealing plate 24 using adhesive (easily removable adhesive). The sealing plate 24 is made of stainless steel. Existing concrete test blocks require natural air drying and solidification, resulting in low drying efficiency. Therefore, this needs improvement. When the molding block 6 contacts the concrete, rotating the sealing plate 24 causes the rotating screw 23 to rotate clockwise and fix into the rotating screw groove 22, thus installing the sealing plate 24 and sealing the drying groove 18. The wear-resistant layer 25 can then directly contact the concrete. When drying is required, the distance between the molding block 6 and the molding mold 7 is moved so that the molding block 6 is above the molding mold 7. Then, the sealing plate 24 is removed, and the drying fan 20 blows air, causing airflow near the molding mold 7, thereby accelerating the molding rate of the concrete test block in the molding mold 7.

[0029] The working principle is as follows: First, concrete is added to the molding mold 7. Then, the electric telescopic rod 4 moves the molding block 6, squeezing the concrete in the molding mold 7 to eliminate air bubbles. After a period of stillness, the concrete fully solidifies, thus forming a concrete test block. Most existing molding molds 7 are fixed, making disassembly difficult. Therefore, it is necessary to make the molding mold 7 easy to disassemble and facilitate the discharge of the formed concrete test block. First, when installing the molding mold 7, one side of the molding mold 7 is made to fit against the outer wall of the first positioning plate 9. Then, the second moving plate 13 is pushed, and the slider 12 moves on the sliding rod 11, causing the adsorption magnet 14 to be attracted to the other side of the molding mold 7, initially positioning the second moving plate 13. Then, the locking screw 17 is fixed into the locking screw groove 16, thus fixing the position of the locking plate 15 and the second moving plate 13, thereby securing the molding mold 7 between the first positioning plate 9 and the second moving plate 13. The process can be reversed during disassembly. During disassembly, the anti-stick coating 8 inside the molding mold 7 prevents the concrete from adhering to its inner wall, facilitating mold disassembly and separation of the molding mold 7 from the concrete test block inside, thus allowing for material discharge. Existing concrete test blocks require natural air drying and solidification, resulting in low drying efficiency. Therefore, this needs improvement. When the molding block 6 contacts the concrete, rotating the sealing plate 24 causes the rotating screw 23 to rotate clockwise and be fixed in the rotating screw groove 22, thus installing the sealing plate 24 and sealing the drying groove 18. The wear-resistant layer 25 can then directly contact the concrete. When air drying is required, the distance between the molding block 6 and the molding mold 7 is moved so that the molding block 6 is above the molding mold 7. Then, the sealing plate 24 is disassembled, and the drying fan 20 blows air, causing airflow near the molding mold 7, thereby accelerating the molding rate of the concrete test block in the molding mold 7.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
