[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-5 As shown, a high-precision mold processing fixing device includes a base 1, on which a first lead screw 2 with positive and negative teeth is mounted. A motor 3 for driving the first lead screw 2 to rotate is mounted on one side of the base 1. Two sets of clamping assemblies are mounted on the upper surface of the base 1. The clamping assemblies include a frame 4, which is threadedly connected to the first lead screw 2. A slider 5 is mounted on the lower surface of the frame 4. A groove 6 that mates with the slider 5 is opened on the upper surface of the base 1. A second lead screw 7 with positive and negative teeth is mounted inside the frame 4. A handle 8 is mounted on one end of the second lead screw 7. Two mounting blocks 9 are mounted on the second lead screw 7 and are threadedly connected to the second lead screw 7. The mounting blocks 9 have two mounting surfaces with an obtuse angle between them. A contact plate 10 is mounted on each of the two mounting surfaces of the mounting blocks 9.

[0020] The base 1 has connecting lugs on its side, which are used to fix the base 1 to the operating table by means of bolts.

[0021] Of the two mounting surfaces on the mounting block 9, one mounting surface is parallel to the side of the frame 4, and the other mounting surface can intersect the side of the frame 4. The former mounting surface is used to fix the rectangular mold, and the latter mounting surface is used to fix the circular mold.

[0022] When the fixed mold is rectangular, the handle 8 is rotated according to the side length of the rectangular mold. The handle 8 drives the second lead screw 7 to rotate, which in turn drives the two mounting blocks 9 on the same lead screw to move simultaneously. The two mounting blocks 9 can move away from each other or closer to each other under the action of the second lead screw 7, so as to make it easy to adjust to a suitable distance for clamping the rectangular mold. After the distance of the mounting blocks 9 is adjusted, the second lead screw 7 stops rotating. Then the rectangular mold is placed in the middle position of the base 1. Then the motor 3 is started, which drives the first lead screw 2 to rotate. The first lead screw 2 is connected to the frame 4 by a thread, and the two frames 4 are moved simultaneously towards the rectangular mold by the cooperation of the slider 5 and the slide groove 6. Then the rectangular mold on the base 1 is fixed by the pressure between the contact plate 10 on one of the mounting surfaces of the mounting block 9 and the rectangular mold.

[0023] When the fixed mold is circular, the handle 8 is rotated according to the diameter of the circular mold. The handle 8 drives the second lead screw 7 to rotate, which in turn drives the two mounting blocks 9 located on the same lead screw to move simultaneously. The two mounting blocks 9 can move away from or towards each other under the action of the second lead screw 7, so as to make it easy to adjust to a suitable distance for clamping the circular mold. After the distance of the mounting blocks 9 is adjusted, the second lead screw 7 stops rotating. Then the circular mold is placed in the middle position of the base 1. Next, the motor 3 is started, which drives the first lead screw 2 to rotate. The first lead screw 2 is threadedly connected to the frame 4, and the two frames 4 are moved simultaneously towards the circular mold through the cooperation of the slider 5 and the slide groove 6. Then, the circular mold on the base 1 is fixed by the pressure between the contact plate 10 on the other mounting surface of the mounting block 9 and the circular mold.

[0024] Furthermore, a groove 11 is provided on the upper surface of the mounting block 9. The groove 11 is used to reduce the mass of the mounting block 9, so as to facilitate the movement of the mounting block 9 by the second lead screw 7, and at the same time reduce the material used in the mounting block 9.

[0025] Furthermore, the upper surface of the base 1 is provided with at least one set of mounting grooves, each set of mounting grooves including four recesses 12, and each mounting block 9 has four recesses 11. The recesses 11 within the same mounting block 9 have the same depth, while the recesses 11 within the four mounting blocks 9 have different depths. Each recess 11 on the mounting block 9 contains a column 13. The column 13 within the same recess 11 on the same mounting block 9 has the same height, while the column 13 within the recesses 11 of the four mounting blocks 9 have different heights. All columns 13 can be inserted into the recesses 12. When it is necessary to raise the upper end of the mold to be fixed above the mounting block 9... When the height of the mold is lower than that of the mounting block 9, a column 13 of appropriate length can be selected according to the thickness of the mold. Then, the column 13 placed in the mounting block 9 is inserted into the sink 12. The outer diameter of the sink 12 is slightly larger than the outer diameter of the column 13 to avoid the column 13 from shaking in the sink 12 and affecting the placement of the mold. At the same time, the inner diameter of the groove 11 is larger than the inner diameter of the sink 12 to facilitate the placement of the column 13. After the column 13 is placed in the sink 12, the mold is placed on the four columns 13. Then, the motor 3 drives the first lead screw 2 to rotate, which drives the mounting block 9 to move, thereby fixing the mold.

[0026] Furthermore, the upper surface of the frame 4 has graduations, which facilitates the quick movement of the mounting block 9 to the appropriate position.

[0027] Furthermore, the included angle between the two mounting surfaces on mounting block 9 is 135°.
