[0024] Refer to Figures 1-4 , a multi-angle cutting and positioning mold for asphalt mixture, comprising a mold body 10, an adjusting disk 20 and a cutting assembly 30. Uniformly distributed limiting rods 11 are provided above the mold body 10. The limiting rods 11 are fixedly connected to the mold body 10. The limiting rods 11 penetrate and are movably connected to the linkage plate 12. An adjusting disk 20 connected movably is provided above the linkage plate 12. Cutting assemblies 30 are provided on both sides of the adjusting disk 20. The cutting assemblies 30 are slidably connected to the lower part of the adjusting disk 20. Symmetrical limiting grooves 21 are opened above the adjusting disk 20. An output rod 33 and a connecting piece 31 are provided inside the limiting grooves 21; the adjusting disk 20 penetrates and is movably connected to the linkage plate 12, and combined with the adjusting disk 20 itself being in the shape of a handwheel, so that rotating the adjusting disk 20 can drive the cutting assembly 30 at the bottom to rotate together, thereby adjusting its cutting angle; the limiting rods 11 are uniformly distributed at the four top corners of the mold body 10; the cutting assemblies 30 are slidably connected to the lower part of the adjusting disk 20 through the connecting pieces 31.

[0025] Further, a threaded rod 22 is provided on one side of the adjusting disk 20. The threaded rod 22 penetrates and is movably connected to the adjusting disk 20. The threaded rod 22 penetrates and is threadedly connected to the connecting piece 31; the threaded rod 22 is a double-threaded rod, and the directions of its thread structures are completely opposite, so that when the threaded rod 22 rotates, the connecting piece 31 can drive the cutting assemblies 30 to approach or move away from each other.

[0026] Further, the connecting member 31 is fixedly connected above the cutting assembly 30, and cutting members 32 are provided on both sides of the cutting assembly 30; the positions where the connecting member 31 is penetrated by the threaded rod 22 and the positions where the connecting member 31 is penetrated by the output rod 33 are staggered with each other.

[0027] Further, the cutting members 32 are embedded and slidably connected to the cutting assembly 30. A linkage lead screw 35 is provided inside the cutting assembly 30, and the linkage lead screw 35 is movably connected to the cutting assembly 30; limiting members are fixedly connected to both sides of the cutting members 32, so that the cutting members 32 can be slidably connected to the cutting assembly 30. The bottom of the cutting assembly 30 is edge-ground, and the end of the cutting member 32 away from the cutting assembly 30 is also an edge-ground part, so as to cut the asphalt mixture.

[0028] Further, both ends of the linkage lead screw 35 are penetrated and threadedly connected to the cutting members 32, and the linkage lead screw 35 is fixedly connected to the linkage bevel gear 36 through penetration; the linkage lead screw 35 is also a double-threaded rod like the threaded rod 22, so when the linkage lead screw 35 rotates, the cutting members 32 can be made to approach or move away from each other.

[0029] Further, the linkage bevel gear 36 is meshed and connected to the output bevel gear 34. The output bevel gear 34 is fixedly connected to the bottom of the output rod 33. The output rod 33 is penetrated and movably connected to the connecting member 31 and the cutting assembly 30; when the output rod 33 rotates, the linkage bevel gear 36 will drive the linkage lead screw 35 to rotate through the output bevel gear 34. Then, after the cutting assembly 30 is inserted into the asphalt mixture, the cutting members 32 move outwards on both sides to complete the cutting of the asphalt mixture.

[0030] Working principle: When using this device, through the set die body 10, adjusting disk 20 and cutting assembly 30, when the asphalt mixture is poured into the die body 10 and semi-cooled, by pressing the linkage plate 12, the adjusting disk 20 and the cutting assembly 30 are driven to perform preliminary cutting on the semi-cooled asphalt mixture plate under the guidance of the limiting rod 11. Then, by rotating the output rod 33, the output bevel gear 34 drives the linkage bevel gear 36 to drive the linkage lead screw 35 to rotate, so that the cutting members 32 on both sides of the cutting assembly 30 move outwards, and finally the asphalt mixture is cut. Finally, the asphalt mixture can be cut and divided into blocks simply and quickly for convenient detection. Compared with manually taking out and cutting, it is more convenient, thus improving the work efficiency; through the set adjusting disk 20 and cutting assembly 30, by rotating the adjusting disk 20, the two cutting assemblies 30 at the bottom are driven to rotate, so as to adjust the cutting angle. Then, by rotating the threaded rod 22, the two cutting assemblies 30 are made to approach or move away from each other, so as to adjust the cutting size. Finally, when cutting the asphalt mixture inside the die, the cutting angle can be adjusted, and the cutting size can also be adjusted, so that different areas can be detected according to needs during detection.

[0031] The above are only the preferred embodiments of the present utility model, and do not thus limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the solutions obtained by equivalent substitutions and obvious changes made by using the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
