[0001] This utility model relates to the field of mold technology, specifically to a three-piece mold for easy-to-disassemble filling body specimens. Background Technology

[0002] Tailings cemented backfill technology is currently the mainstream method for underground mine backfilling. Its principle involves mixing tailings, cementing materials, and water in a specific ratio to form a backfill slurry, which is then transported to the goaf. After solidification, it forms a backfill body with a certain strength, thereby maintaining the stability of the stope and surrounding rock. To test the performance of the backfill body, standard-sized test specimens need to be prepared beforehand. Typically, these specimens are made into standard cubes of 70.7mm × 70.7mm × 70.7mm.

[0003] Existing filling specimen fabrication processes generally employ integral steel molds. However, this type of mold has significant drawbacks in demolding: on the one hand, the demolding process is cumbersome and inconvenient to operate; on the other hand, the filling specimens are easily damaged during demolding, thereby reducing the yield of specimens.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 and Figure 2As shown, this utility model includes a base plate 1, with first side plates 2 vertically arranged on the front and rear sides of the base plate 1, and second side plates 3 vertically arranged on the left and right sides of the base plate 1. Two detachable movable partitions 4 are arranged longitudinally at equal intervals on the top of the base plate 1, and the two movable partitions 4 divide the square cavity formed by the base plate 1 and the side plates into three equally sized cavities 5 (cubic cavities with a side length of 70.7 mm).

[0032] like Figure 3 As shown, a first guide plate 14 is provided horizontally at the bottom of the inner wall of the first side plate 2, and two first snap-fit ​​grooves 19 corresponding to the movable partition 4 are also provided longitudinally and equidistantly in the middle of the inner wall of the first side plate 2.

[0033] like Figure 4 As shown, a second guide plate 16 is provided laterally at the bottom of the inner wall of the second side plate 3, and connecting grooves 13 for fixing to the first side plate 2 are provided longitudinally on both sides of the inner wall of the second side plate 3. Combined with... Figure 1 and Figure 2 As shown, each of the second side plates 3 has a fixing bolt 22 on both sides of its top for fixing the second side plate 3 to the first side plate 2 through it. The fixing bolt 22 is located at the top of each connecting groove 13 and is fixed from the outside of the second side plate 3 to the side of the first side plate 2.

[0034] like Figure 5 As shown, the movable partition 4 has first locking blocks 18 on its left and right sides, which are used to slide and insert into the corresponding first locking slots 19. The bottom of the movable partition 4 also has a second locking block 20.

[0035] like Figure 6 As shown, the top surface of the base plate 1 has two second locking grooves 21 corresponding to the movable partition 4 in a transverse direction. First guide grooves 15 are respectively opened on the front and rear sides of the side wall of the base plate 1, and second guide grooves 17 are respectively opened on the left and right sides of the side wall of the base plate 1. Combined with... Figure 1 and Figure 2 As shown, the second locking block 20 is inserted into the corresponding second locking groove 21, the first guide groove 15 is inserted into the first guide plate 14, and the second guide groove 17 is inserted into the second guide plate 16. By setting multiple sets of guide plates and guide grooves to be inserted into each other, the stability of the device after assembly is improved, ensuring that the shape and size of the filling specimens made using the device meet the standards; and it also limits the movement of the side plate, restricting the trajectory of the side plate's linear movement.

[0036] like Figure 7As shown, a bidirectional lead screw 6 is installed through the base plate 1 along the front-back direction, and the bidirectional lead screw 6 is located below the first guide groove 15. Each of the first side plates 2 has a threaded hole in the center of its bottom. The threaded portions at both ends of the bidirectional lead screw 6 are threadedly connected to the threaded holes of the two first side plates 2 and are rotatably connected. The base plate 1 has a mounting cavity 8 in its center for mounting a first bevel gear 9 and two second bevel gears 10. The first bevel gear 9 is annularly positioned around the center of the bidirectional lead screw 6, and a threaded rod 7 is provided on each of its left and right sides. Each threaded rod 7 is located below the second guide groove 17. The inner end of each threaded rod 7 is provided with a second bevel gear 10 for meshing with the first bevel gear 9, and the outer ends of the two threaded rods 7 have opposing threaded portions. Each of the second side plates 3 has a threaded hole in the center of its bottom, and the threaded portions on the two threaded rods 7 are threadedly connected to the threaded holes of the two second side plates 3 and are rotatably connected.

[0037] By setting up a bidirectional lead screw 6 in conjunction with two threaded rods 7, automatic disassembly between the four side plates and the bottom plate 1 is achieved, thereby facilitating the demolding of the filling specimen, enabling operators to efficiently complete the demolding operation, and saving labor costs; moreover, this disassembly method can effectively prevent damage to the filling specimen during the removal process, and improve the yield of the filling specimen.

[0038] Limiting blocks 11 are fixed to both ends of the bidirectional lead screw 6 and the outer ends of each threaded rod 7. The limiting blocks 11 are located on the outer side of each side plate. A turntable 12 is also provided on the limiting block 11 at the front end of the bidirectional lead screw 6. By setting the turntable 12, the convenience of operation for the operator is further improved, and it is convenient to manually rotate the bidirectional lead screw 6, thereby realizing the convenience of side plate movement.

[0039] The method of using the easily detachable and assembleable triple mold for filling body specimens described in this utility model is as follows:

[0040] After assembling the device, slide the two movable partitions 4 downwards and insert them between the two first side plates 2 to divide the device into three equal-sized cavities 5. Add the filling slurry into the three cavities 5. After the slurry has completely solidified, remove the four fixing bolts 22 to unlock the fixed connection between the second side plate 3 and the first side plate 2.

[0041] By holding the turntable 12 and rotating it, the two first side plates 2 move outwards under the rotation of the double-acting screw 6, and the first guide plate 14 gradually withdraws from the first guide groove 15. At the same time, the first bevel gear 9 drives the two second bevel gears 10 to rotate synchronously, which in turn drives the two threaded rods 7 to rotate. The two second side plates 3 also move outwards under the rotation of the threaded rods 7, and the second guide plate 16 gradually withdraws from the second guide groove 17. When each side plate moves outwards to contact the limiting block 11 (before the guide plates are completely withdrawn from the guide grooves), stop rotating the turntable 12 and remove the movable partition 4 upwards. This completes the removal of all templates on the outside of the filling specimen (demolding operation). Afterwards, remove the filling specimens one by one upwards, thus completing the manufacturing process of this filling specimen.

[0042] Before the next filling specimen is made, hold the turntable 12 and rotate it in the opposite direction to drive the double-ended lead screw 6 to rotate. Through the transmission between the bevel gears, the two threaded rods 7 will rotate synchronously, so that the four side plates will move back to the side of the base plate 1. All the guide plates will retract into the guide groove. Then, insert the movable partition 4 one by one between the two first side plates 2 to restore the initial state of making the filling specimen. Repeat the above operation to make the filling specimen repeatedly.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
