[0022] Therefore, for the installation and use of the plaster mold 3, firstly, the limiting groove body 32 at the bottom end center position of the mold base 31 is inserted into the limiting boss body 13 at the top center position of the rotating disc 11, which provides a limiting function for the butt joint of the rotating disc 11 and the mold base 31 in the horizontal direction, i.e., makes the center lines of the plaster mold 3 and the rotating disc 11 lie on the same straight line; during the insertion process of the limiting boss body 13 and the limiting groove body 32, the outer side walls of the rotating disc 11 and the mold base 31 are wrapped and limited by the stable wrapping ring 404 arranged thereon, so as to avoid the problem of positional deviation during the rotation operation of the two; then the butt joint of the rotating disc 11 and the mold base 31 is fastened and connected by the fastening assembly arranged thereon, which can provide a fastening effect in both the horizontal and vertical directions, and ensure the stability of the connection of the two, which has a positive effect on the processing of the base body.

[0023] The specific steps for installing and using plaster mold 3 are as follows: First, refer to the attached... Figures 2-6 As shown, the limiting groove 32 at the bottom of the mold base 31 and the limiting boss 13 at the top of the rotating disk 11 are inserted together to provide calibration positioning. Furthermore, an auxiliary calibration component is provided to assist in calibration, specifically by wrapping the outer surfaces of both the mold base 31 and the rotating disk 11 with a stabilizing wrapping ring 404. This auxiliary calibration component includes calibration slots 401 equidistantly arranged on the top of the rotating disk 11 and first stabilizing side grooves 402 equidistantly arranged on the outer wall of the rotating disk 11. The auxiliary calibration component also includes a second stabilizing side groove 403 on the outer wall of the mold base 31. The number of sets of the second stabilizing side groove 403 and the first stabilizing side groove 402 are the same, and their positions correspond. When the limiting groove 32 at the bottom of the mold base 31 and the limiting boss 13 at the top of the rotating disk 11 are inserted, the second stabilizing side groove 403 on the outer wall of the mold base 31 and the first stabilizing side groove 402 on the outer wall of the rotating disk 11 are joined to form a stabilizing limiting groove.

[0024] The specific operation is as follows: before placing the mold base 31 on the rotating disk 11, the stabilizing wrapping ring 404 needs to be installed first. That is, the stabilizing wrapping ring 404 is put on the rotating disk 11, and the positioning protrusion 405 on the inner side wall of the stabilizing wrapping ring 404 is aligned with the first stabilizing side groove 402 on the outer side wall of the rotating disk 11. At the same time as the stabilizing wrapping ring 404 is put on the outer side of the rotating disk 11, the positioning protrusion 405 slides into the first stabilizing side groove 402 until the bottom end of the stabilizing wrapping ring 404 contacts the protruding side body 12 on the bottom side of the rotating disk 11.

[0025] Next, the plaster mold 3 is installed and placed. While aligning the mold base 31 at the bottom of the plaster mold 3 with the rotating disk 11, it is also necessary to align the second stabilizing groove 403 on the outer ring surface of the mold base 31 with the positioning protrusion 405 on the inner side of the stabilizing wrapping ring 404.

[0028] Then the connection of the mold base 31 and the rotating disc 11 is provided with a fastening effect by the cooperation of the connecting column body 505 and the fastening stud 511; the top gland 506 is fixedly provided at the top end of the connecting column body 505, and the elastic pad body 507 is fixedly provided at the bottom side of the top gland 506; the top gland 506 is matched and clamped with the clamping cavity 504 at the top of the butt joint through groove 503, and the top end surface of the top gland 506 is flush with the cavity opening of the clamping cavity 504; that is, the connecting column body 505 needs to be inserted into the butt joint through groove 503 on the mold base 31, and then the connecting column body 505 will enter the calibration slot 401 on the rotating disc 11, until the top gland 506 at the top of the connecting column body 505 is clamped in the clamping cavity 504; it needs to be noted that when the top gland 506 is clamped in the clamping cavity 504, the top end surface of the top gland 506 will protrude from the cavity opening of the clamping cavity 504.

[0029] Again from the attached Figure 7 and the attached Figure 8The content of the display can be known that after the connecting column body 505 is inserted into the calibration slot 401, in order to better cooperate with the fastening stud 511 to provide a fastening effect, the scheme also provides a fastening card slot 508 on one side of the connecting column body 505, an auxiliary slope body 509 is provided on the inner side bottom of the fastening card slot 508; Anti-skid convex bodies 510 are provided on the inner side wall of the fastening card slot 508 and the auxiliary slope body 509; That is, after the connecting column body 505 is inserted into the calibration slot 401, the auxiliary slope body 509 in the fastening card slot 508 on one side of the connecting column body 505 is aligned with the through screw groove 501 on the rotating disc 11, and then the fastening stud 511 is used to cooperate with it to realize fastening connection.

[0030] The specific operation in this process is that the fastening stud 511 is threadedly connected with the through screw groove 501 through the round hole body 502 in the stable wrapping ring 404, an auxiliary rubber cylinder 512 is further sleeved on the fastening stud 511, the auxiliary rubber cylinder 512 is used to improve the stability of the thread connection of the fastening stud 511 with the through screw groove 501; A spherical surface is provided on the front end of the fastening stud 511; That is, after the connecting column body 505 is inserted into the calibration slot 401, the fastening stud 511 is installed, and the auxiliary rubber cylinder 512 is first sleeved on the fastening stud 511, and then the front end of the fastening stud 511 is inserted into the round hole body 502 outside the stable wrapping ring 404, when the fastening stud 511 reaches the through screw groove 501, the fastening stud 511 is threadedly connected with the through screw groove 501, until the front end of the fastening stud 511 reaches the position of the auxiliary slope body 509 at the bottom side of the through screw groove 501, and then the fastening stud 511 is continuously rotated, while the front end of the fastening stud 511 is extruded against the auxiliary slope body 509, which drives the connecting column body 505 to move downward, thereby driving the top gland 506 at the top of the connecting column body 505 to press downward, on the one hand, the top gland 506 is pressed against the elastic pad 507, and on the other hand, a downward pressure is provided to the mold base 31, which has a positive effect on improving the stability of the butt joint of the mold base 31 and the rotating disc 11; Finally, the fastening stud 511 is tightened; After the fastening stud 511 is tightened, the front end of the fastening stud 511 is in the fastening card slot 508, and the anti-skid convex body 510 in the inner side of the fastening card slot 508 is in contact with the fastening stud 511; The top gland 506 provided at the top of the connecting column body 505 is completely inserted into the clamping cavity 504, that is, the top end face of the top gland 506 is flush with the cavity opening of the clamping cavity 504; On the other hand, the screw head at the tail end of the fastening stud 511 extrudes the auxiliary rubber cylinder 512, which provides a stable effect for the connection of the fastening stud 511.

[0031] That is, through the cooperation of the connecting column 505 and the fastening stud 511, the stable effect can be provided in the horizontal and vertical directions at the same time, and the connection stability is better.

[0032] On this basis, combined with the attached Figure 5 As shown, in the subsequent use process, if the connection of the fastening stud 511 is loose, that is, the fastening stud 511 will move outward along the axial direction, at this time, the extrusion of the fastening stud 511 to the bottom side auxiliary slope body 509 in the fastening slot 508 will be reduced or even eliminated, at the same time, the elastic pad body 507 arranged at the bottom end of the top gland 506 will press upward on the top gland 506, the top end face of the top gland 506 will exceed the cavity opening of the clamping cavity body 504, that is, it is obviously exposed, which is convenient for the staff to confirm whether the connection is loose, and then timely maintenance and recovery can be carried out, and the stable processing in the subsequent process is ensured.
