[0026] Specifically, in this structure, the left side plate 30 can rotate with the corresponding support plate 12 through the shaft pin 4, and the right side plate 31 can rotate with the corresponding support frame 2 through the rotating rod 5. The two ends of the front side plate 32 and the right side plate 31 are installed between the left side plate 30 and the right side plate 31 by screws, thereby forming an overall angle box structure, and at the same time, it is convenient to achieve the effect of disassembly and assembly;

[0027] The two inner plates 6 are symmetrically connected by screws to form an inverted trapezoidal mold structure between the front side plate 32 and the rear side plate 33, which is convenient for disassembly and assembly;

[0028] In summary, the left side plate 30, the right side plate 31, the front side plate 32, the rear side plate 33 and the two inner plates 6 constitute the upper angle box as a whole, and they can be disassembled and assembled with each other.

[0029] In a specific embodiment, as shown in the attached Figure 2 , 3 As shown in Figure 4, a deflection angle measuring structure is arranged on the outside of the rotating rod 5, and the deflection angle measuring structure includes an angle disk 7, and the angle disk 7 is embedded in the outer wall of the supporting frame 2. A turntable 8 is fixedly installed on the outside of the rotating rod 5, and an indicator needle 9 is fixedly arranged on the surface of the turntable 8, and the indicator needle 9 is attached to the surface of the angle disk 7. One end of the rotating rod 5 is connected to the right side plate 31, and the rotating rod 5 is rotatably connected to the supporting frame 2. A fixed disk 10 is arranged at one end of the rotating rod 5, and a handle 11 is arranged at one end of the fixed disk 10.

[0030] Specifically, in this structure, when the angle adjustment of the angle box is required, the handle 11 first drives the fixed plate 10 to rotate, so that the fixed plate 10 drives the rotating rod 5 to rotate at the support frame 2, and the rotating rod 5 drives the right side plate 31 to rotate, and the right side plate 31 drives the angle box body 3 assembled with each other to rotate at an angle, and the left side plate 30 rotates at the corresponding support frame 2 through the shaft pin 4, so as to achieve the angle adjustment effect of the angle box body 3;

[0031] When the rotating rod 5 rotates, the rotating disk 8 drives the indicator needle 9 to rotate in contact with the angle disk 7. The angle disk 7 is engraved with angles from 0 degrees to 360 degrees. The pointer rotates in contact with the angle disk 7, which can facilitate the operator to more intuitively understand the deflection angle value of the angle box body 3.

[0032] In a specific embodiment, as shown in the attached Figure 4 , 5 As shown, a limiting assembly is provided at the bottom of the fixed disk 10, wherein the limiting assembly includes a support plate 12, the support plate 12 is fixedly mounted on the outer wall of the support frame 2 and is located at the bottom of the fixed disk 10, a plurality of positioning holes 13 are provided in a ring-shaped outer wall of the fixed disk 10, a sleeve 14 is provided on the top of the support plate 12, a positioning rod 15 is slidably provided inside the sleeve 14, the positioning rod 15 is adapted to the structure of the positioning hole 13, and toggle rods 16 are fixedly installed at both ends of the positioning rod 15, a movable block 17 is provided inside the sleeve 14 at the bottom end of the positioning rod 15, a spring 18 is provided at the bottom of the movable block 17, and the top and bottom ends of the spring 18 are respectively connected to the bottom of the movable block 17 and the bottom of the inner cavity of the sleeve 14.

[0033] Specifically, in this structure, the rotating rod 5 will drive the fixed disk 10 to rotate when it rotates. The operator slides the toggle rod 16 downward to make the positioning rod 15 slide inside the sleeve 14 and squeeze the spring 18 through the movable block 17. When it is rotated to a suitable angle, the operator releases the toggle rod 16, and the spring 18 is reset after being squeezed, so that the positioning rod 15 extends to the inside of the positioning hole 13 opened in the fixed disk 10, thereby limiting the fixed disk 10 and preventing the rotating rod 5 from rotating without reason and causing the angle of the angle box body 3 to deflect.

[0034] Working principle of this utility model:

[0035] When the above structure is used, the handle 11 is first rotated to drive the fixed plate 10 to rotate, and the fixed plate 10 drives the rotating rod 5 to rotate at the support frame 2, and the rotating rod 5 drives the right side plate 31 to rotate, and the right side plate 31 drives the angle box body 3 assembled with each other to rotate at an angle, and the left side plate 30 is rotated at the corresponding support frame 2 through the shaft pin 4, so that the angle box body 3 is rotated to a corresponding angle according to production requirements;

[0036] After the mold is placed inside the assembled angle box body 3, pouring begins. After the casting solidifies, take out the casting to complete the pouring;

[0037] When the rotating rod 5 rotates, the rotating disk 8 drives the indicating needle 9 to rotate in contact with the angle disk 7. The indicating needle rotates in contact with the angle disk 7, which can facilitate the operator to more intuitively understand the deflection angle value of the angle box body 3 and improve the accuracy of the angle deflection of the angle box body 3.

[0038] When the rotating rod 5 rotates, the fixed plate 10 is driven to rotate. The operator slides the toggle rod 16 downward to make the positioning rod 15 slide inside the sleeve 14 and squeeze the spring 18 through the movable block 17. When the rotation reaches a suitable angle, the operator releases the toggle rod 16, and the spring 18 is reset after being squeezed, so that the positioning rod 15 extends to the inside of the positioning hole 13 provided in the fixed plate 10, thereby limiting the fixed plate 10, preventing the rotating rod 5 from rotating without reason and causing the angle box body 3 to deflect at an angle, and the operator does not need to constantly support the handle 11 to prevent the angle box body 3 from deflecting without reason;

[0039] The front side plate 32 and the rear side plate 33 in the angle box body 3 can be removed from the left side plate 30 and the right side plate 31 respectively by screws, and the two inner plates 6 can also be removed by screws, thereby realizing the split operation of the angle box body 3, which is convenient for operators to use.
