In use of the calibration assembly 8, the wax pattern 9 is first sleeved on the mounting shaft 230 of the wax pattern carrier 23 such that the first insert 91 of the wax pattern 9 is positioned slightly to the left of the positioning rib 237 in fig. 13. The method of sleeving the wax pattern 9 on the mounting shaft 230 of the wax pattern carrier 23 is the same as that described above, and will not be repeated here for the sake of brevity. Next, the wax pattern carrier 23 is mounted on the fixing base 81, specifically: the first insertion portion 231 of the mounting shaft 230 of the wax mold carrier 23 is inserted into the slot 811 via the inlet and outlet 812, and the positioning protrusion 237 is located in the inlet and outlet 812, and the second insertion portion 235 of the mounting shaft 230 is supported in the limiting groove 816 on the second base 814. Then, the lifting frame 83 is driven to move downwards by the lifting driving piece 85, so that the plurality of elastic positioning pieces 84 are respectively elastically abutted with the plurality of wax patterns 9 on the wax pattern carrier 23. In the present embodiment, the lifting frame 83 is driven by the lifting driving member 85 to move along the slide bar 825 toward the wax pattern carrier 23 until one ends of the positioning pins 842 of the plurality of elastic positioning members 84 elastically abut against the surfaces of the plurality of wax patterns 9, respectively, and the elastic members 843 of the elastic positioning members 84 are compressed.

Then, the swing driving member 86 drives the turret 82 to swing around the center axis of the wax pattern carrier 23. Referring to fig. 14 and 15, in the present embodiment, in the initial state, the plurality of elastic positioning members 84 and the positioning protrusions 237 are located on the same line; when the motor shaft of the driving motor 861 rotates, the rotating frame 82 and the plurality of elastic positioning pieces 84 connected with the rotating frame 82 can swing left and right by matching the first connecting arm 862, the second connecting arm 863 and the guide rail 865 by taking the central shaft of the wax mold carrier 23 as the rotation center, specifically, the driving motor 861 drives the first connecting arm 862 to rotate clockwise in fig. 15, and the first connecting arm 862 drives the second connecting arm 863 to reciprocate along the guide rail 865: first, the first connecting arm 862 drives the second connecting arm 863 to move along the arc slot 867 to the straight slot 868 located at the uppermost position, in this process, taking the perspective of fig. 13 as an example, the turret 82 swings leftwards with the central axis of the wax pattern carrier 23 as the rotation center, and then, when the first connecting arm 862 drives the second connecting arm 863 to move along the arc slot 867 to the straight slot 868 located at the lowermost position through the straight slot 868, the turret 82 swings rightwards with the central axis of the wax pattern carrier 23 as the rotation center; finally, the first connecting arm 862 drives the second connecting arm 863 to move from the lowest straight slot 868 to the arc-shaped slot 867 for resetting, and the motor shaft of the driving motor 861 completes one rotation. During the swinging process of the elastic positioning piece 84 along with the rotating frame 82, the positioning pin 842 of the elastic positioning piece 84 abuts against the surface of the wax mould 9, the elastic piece 843 is compressed under the pressure of the positioning pin 842, and when the elastic positioning piece 84 contacts with the first rabbet 91, the positioning pin 842 moves towards the first rabbet 91 and is clamped with the first rabbet 91 under the action of the elastic restoring force of the elastic piece 843; after the locating pin 842 is clamped with the first insert hole 91 of the wax pattern 9, the wax pattern 9 can rotate along with the swing of the locating pin 842, when the motor shaft of the driving motor 861 rotates for one circle, the plurality of elastic locating pieces 84 move along with the rotating frame 82 and return to the initial state, at this time, the plurality of elastic locating pieces 84 and the locating convex strips 237 are positioned on the same straight line, and because the elastic locating pieces 84 are clamped with the first insert hole 91, at this time, the first insert holes 91 of the plurality of wax patterns 9 and the locating convex strips 237 are also positioned on the same straight line, thereby realizing the accurate location of the wax pattern 9. Because the first insert 91 is located slightly toward the left side of the positioning protrusion 237 in fig. 13 when the wax pattern 9 is placed on the wax pattern carrier 23, the area of the wax pattern 9 located on the right side of the positioning protrusion 237 has no insert 90, so when the turret 82 swings left about the center axis of the wax pattern carrier 23 as the center of rotation, one end of the elastic positioning member 84, which is close to the wax pattern 9, moves toward the right side of the center axis of the wax pattern 9, and the elastic positioning member 84 elastically abuts against the surface of the wax pattern 9; then, when the turret 82 swings rightward about the central axis of the wax pattern carrier 23 as a rotation center, the end of the elastic positioning member 84, which is close to the wax pattern 9, moves toward the left side of the central axis of the wax pattern 9, and during this process, the elastic positioning member 84 will first encounter the first insert 91 on the wax pattern 9 and be engaged with the first insert 91, so that it can be ensured that the elastic positioning member 84 can only be engaged with the first insert 91 during the reciprocating swing process.

After the positions of the insert openings 90 of the wax patterns 9 are adjusted, the sliding driving piece 879 drives the abutting rod 878 to move towards the wax pattern carrier 23 through the sliding seat 872, and abuts against the positioning ring 238 farthest from the first base 810 through the abutting rod 878, so that a pressure is applied to the positioning ring 238 to further clamp the wax patterns 9, and the wax patterns 9 are prevented from moving accidentally; the second buffer spring 876 is compressed by the pressure of the connection sleeve 875. In this process, the pressure applied to the slider 872 is detected by a pressure sensor on the slider 872, and the pressure is the same as the reaction force of the slider 872 to the positioning ring 238; when the pressure sensor detects that the pressure applied to the slide 872 reaches the preset range, it indicates that the pressure applied to the slide 872 against the positioning ring 238 and the wax pattern 9 has reached the desired pressure value, and at this time, the sliding driving member 879 stops moving after receiving the signal from the pressure sensor. The sliding seat 872 can buffer the movement of the sliding seat 872 by arranging a second buffer spring 876, so that the wax mould 9 is prevented from being damaged; and the pressure sensor is matched, so that the pressure applied to the wax mould 9 by the sliding seat 872 can be controlled, and the damage to the wax mould 9 is further avoided.

After the wax pattern 9 is fixed, the sliding driving piece 879 drives the abutting rod 878 to move away from the wax pattern carrier 23 through the sliding seat 872 so as to separate from the wax pattern carrier 23; the lifting frame 83 is driven to move upwards by the lifting driving piece 85, so that the plurality of elastic positioning pieces 84 are separated from the first insert openings 91 of the plurality of wax patterns 9 on the wax pattern carrier 23, and finally the wax pattern carrier 23 is taken off from the fixing seat 81.

It will be appreciated that in other embodiments, the conveyor track 4 may be fixedly connected to the frame 1, or to both the frame 1 and the directional screening mechanism 3.

The foregoing description is directed to the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the invention, and all equivalent changes or modifications made under the technical spirit of the present invention should be construed to fall within the scope of the present invention.
