Description

Technical Field

[0001] The invention relates to the technical field of artificial silica sand shaping, in particular to an artificial silica sand shaping device and shaping process for casting. Background Art

[0002] Artificial silica sand is the raw sand used in 3D printing. As the key raw material in 3D printing technology, the performance and use effect of 3D printing raw sand directly affect the quality and efficiency of the final printed product. Among them, stable performance is an important characteristic that high-quality 3D printing raw sand must possess, which is mainly reflected in its key characteristics such as particle size distribution, shape, hardness and wear resistance. The stability of these properties can effectively ensure the uniform flow and stacking of materials during the printing process, and then ensure that the final printed product has excellent qualities such as uniform structure and precise size. In order to make artificial silica sand meet the needs of use, it is necessary to shape and cast artificial silica sand to make its quality stable, gradation adjustable, and rounded grains, which fully meet the requirements of the coated sand process standards. In the subsequent use process, it can effectively solve casting defects such as sand sticking and sintering of castings, reduce the scrap rate of castings, and produce sand cores with good surface quality and high surface finish of castings. In addition, it has good disintegration and the castings are easier to clean.

[0003] At present, during the shaping process of artificial silica sand in the shaping equipment, the degree of grinding of each artificial silica sand is not exactly the same. Some artificial silica sand that has been ground in advance cannot be screened out from other silica sands in time and can only be mixed with many silica sands to continue to be ground, causing the pre-ground silica sand to gradually become smaller or broken, and then cannot meet the needs and become waste. A certain amount of silica sand waste will be generated in the entire shaping process, which will in turn cause some cost waste.

Four synchronous wheels 13 are respectively fixedly mounted on the output rods of the two driving motors 12 and the two adapter shafts 9. The four synchronous wheels 13 are linearly distributed, and two synchronous belts 14 are respectively sleeved on the four synchronous wheels 13. An exhaust pipe 15 is fixedly mounted on the top of the tank body 2, and the exhaust pipe 15 is composed of a The tank body 2 is composed of a curved pipe, a straight pipe, a sleeve and a transverse pipe. The curved pipe and the straight pipe are both fixedly mounted on the top of the tank body 2. The sleeve is fixedly sleeved on the curved pipe.

Circular holes are opened on the two sliding blocks 24, and the two threaded rods 25 pass through the two circular holes.

[0043] In this embodiment, a process for shaping artificial silica sand for casting is also provided, which is as follows:

[0044] When it is necessary to shape the artificial silica sand, start the drive motor 1 4 and the two drive motors 2 12. The drive motor 1 4 drives the connecting rod 5 fixedly connected thereto. The rotation speed of the connecting rod 5 is slowed down by the reducer 6. Driven by the connecting rod 5, the adapter shaft 1 3 will drive the grinding roller 1 7 to rotate. After the two drive motors 2 12 are started, they will drive the two synchronous wheels 13 fixedly connected thereto. Under the cooperation of the four synchronous wheels 13 and the two synchronous belts 14, the two adapter shafts 2 9 will drive the two grinding rollers 2 10 to rotate simultaneously.

[0045] After that, the silica sand that needs to be shaped is poured into the upper hopper 17, and the silica sand in the upper hopper 17 will gradually slide into the tank body 2 along the connecting pipe 18. As the grinding roller 1 7 and the two grinding rollers 2 10 rotate, the silica sand will roll and rub in the tank body 2, and the silica sand will be polished and impacted, so as to complete the grinding of the silica sand. The shape of the silica sand will become more rounded, and some silica sand that has been ground in advance and has reached the standard shape will gradually pass through the through hole 30 and fall to the bottom of the tank body 2, while the silica sand that has not been ground well and has a larger shape will continue to stay on the top of the circular plate 1 29 for further shaping.

[0046] The shaped silica sand will be accumulated at the bottom of the tank body 2. The baffle plate will be rotated subsequently to clean the silica sand out of the tank body 2 through the discharge port 19. The dust generated by the shaping in the tank body 2 will be discharged outward through the exhaust pipe 15. After a period of use, the electric push rod 32 can be started. The output rod of the electric push rod 32 will gradually output outward to push the circular plate 2 33 to move upward. While the circular plate 2 33 moves, it drives multiple dredging rods 34. The multiple dredging rods 34 will gradually penetrate the multiple through holes 30, squeeze out the silica sand stuck in the multiple through holes 30, and realize the dredging of the multiple through holes 30, so that the multiple through holes 30 remain unobstructed and the screening of the silica sand is not affected.

[0047] When the circular plate 29 needs to be cleaned or replaced later, it is only necessary to rotate the two threaded rods 25 in succession, and the two threaded rods 25 will gradually slide out of the two sliding blocks 24 until the two annular blocks contact the inner walls of the two sides of the two inner cavities 22. At this time, the positions of the two threaded rods 25 are restricted, and then the control of the two threaded rods 25 can be stopped, and the two sliding blocks 24 are driven by the arc plate 26 to slide the sliding blocks 24 out of the two inner cavities 22. During the movement of the arc plate 26, the circular plate 1 29 and the circular plate 2 33 can be taken out of the tank body 2, which is more convenient and quick to operate.

[0048] Compared with the related art, the artificial silica sand shaping device and shaping process for casting provided by the present invention have the following beneficial effects:

[0049] In this method, by utilizing the cooperation of the rotating grinding roller 1 7 and two grinding rollers 2 10 and a plurality of strip grinding blocks 11, the artificial silica sand entering the tank body 2 can be ground and shaped, and the shape of the artificial silica sand can be shaped. When the silica sand is shaped in the tank body 2, it is intercepted by the circular plate 1 29. The silica sand will undergo a series of operations above the circular plate 1 29. The silica sand that has been shaped in advance will pass through the through hole 30 and fall to the bottom of the tank body 2, and will be distinguished from the silica sand that has not been shaped. This can avoid excessive processing of the silica sand that has been shaped, thereby avoiding the generation of waste and reducing a certain amount of waste. In addition, after being distinguished, the remaining silica sand will be used for more activity space, which is convenient for the silica sand to undergo shaping.

A rectangular block 55 is fixedly installed on the hopper 53. 5. A rotating plate 56 is rotatably mounted on the rectangular block 55. The rotating plate 56 contacts the bottom of the hopper 53.

[0056] In this embodiment

[0057] In the prior art, the loading hopper 17 is located at a relatively high position, and it is very laborious to rely on manual climbing to a high place to complete the loading operation. In order to save time and energy, auxiliary equipment can be used. In the initial state, the left side of the moving block 45 is in contact with the welding block 2 42, and the pulling line 1 49 is in the unwinding state, the four supporting wheels 62 at the bottom of the hopper 53 are all in contact with the ground, the output rod of the electric push rod 2 58 is in a retracted state, and the rotating plate 56 maintains contact with the bottom of the hopper 53.

[0058] Pour an appropriate amount of silica sand that needs to be shaped into the hopper 53, and then start the driving motor four 47. The driving motor four 47 will drive the rotating rod 46 fixedly connected thereto to rotate, and the rotating rod 46 drives the winding wheel 48 fixedly connected thereto. During the rotation of the winding wheel 48, the pulling line 49 will be gradually wound around the winding wheel 48. Through the traction of the pulling line 49, the hopper 53 will gradually move upward until the hopper 53 is lifted to a predetermined height, and the driving motor four 47 will automatically close. At this time, the discharge port 54 at the bottom of the hopper 53 will be very close to the upper hopper 17.

[0059] Then start the driving motor three 44, and the output shaft of the driving motor three 44 will drive the threaded rod two 43 fixedly connected thereto. Restricted by the cooperation of the two docking rods, the moving block 45 will gradually move to the right on the threaded rod two 43. While moving, the moving block 45 will drive the material hopper 53, thereby moving the material hopper 53 in the direction of the upper hopper 17 until the material hopper 53 is located directly above the upper hopper 17, and then the driving motor three 44 will automatically turn off.

[0060] Finally, start the electric push rod 2 58, and the output rod of the electric push rod 2 58 will gradually output outwards, driving the square block 59 to move downward. During the downward movement of the square block 59, the originally tight pulling wire 2 60 will gradually relax, and the rotating plate 56, which is kept in place by the pulling force of the pulling wire 2 60, will gradually rotate clockwise on the rectangular block 55. As the rotating plate 56 continues to move downward, the originally blocked discharge port 54 will gradually be opened, and the silica sand in the hopper 53 will slowly pour down and fall into the upper hopper 17. The control of completing the loading can control the opening degree of the rotating plate 56 through the electric push rod 2 58, and then adjust the discharge speed of the hopper 53 to avoid spilling of silica sand, making the loading process more time-saving and labor-saving.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
