[0002] Precision molds are tools with high tolerance levels and low surface roughness, used to form precision parts, and are widely used in electronics, medical, aerospace and other fields.

[0003] In the production process of precision molds, grinding machines are often used to polish the molds. In traditional grinding machines, the grinding disk is usually fixedly mounted on the saddle, and the position of the grinding wheel can be adjusted up and down. Because some workpieces require a deep grinding depth, but the grinding wheel needs to grind from the surface of the workpiece, the position of the grinding wheel can only be adjusted during the workpiece grinding process. However, the height control mechanism of the grinding wheel is often installed at the top, which makes it impossible for the operator to effectively observe the positional relationship between the grinding wheel and the workpiece during the adjustment process. This can lead to problems such as excessive grinding depth, and the operation is also quite cumbersome.

[0004] Therefore, we provide a grinding device for precision mold production. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A grinding device for precision mold production, such as Figures 1-4 As shown, it includes a grinding machine base 1, a saddle 2 slidably connected to the upper end of the grinding machine base 1, a height adjustment component 4 is provided inside the saddle 2, and a disk 3 is connected to the height adjustment component 4.

[0025] The height adjustment assembly 4 includes a rotating connecting rod 401 rotatably disposed inside the height adjustment assembly 4. One end of the rotating connecting rod 401 is inserted into a screw 402. A screw cylinder 403 is sleeved on the outside of the screw 402. Two trapezoidal sliders 404 are symmetrically mounted on the outer surface of the screw cylinder 403. A height adjustment block 405 is slidably connected to the inclined end surface of the trapezoidal slider 404. A rotating support block 406 is disposed on the outside of the height adjustment block 405.

[0026] The disk 3 is positioned above the saddle 2, with a gap between the disk 3 and the saddle 2. The disk 3 has a component storage slot 301 inside, and both ends of the screw 402 are rotatably connected to the inner wall of the component storage slot 301. One end of the rotating connecting rod 401 extends out of the outer surface of the disk 3.

[0027] A movable block is slidably connected to one side surface of the grinding machine base 1. The outer end of the rotating connecting rod 401 is rotatably connected to the movable block, and a handle is connected to the outer end of the rotating connecting rod 401.

[0028] The screw 402 and the screw barrel 403 are screwed together, and the lower end of the trapezoidal slider 404 is slidably connected to the inner wall of the lower end of the component storage groove 301.

[0029] The upper end of the trapezoidal slider 404 is inserted into the inner wall of the upper end of the component storage slot 301, and the upper ends of the two trapezoidal sliders 404 are simultaneously fixedly connected to the lower end of the disk 3.

[0030] The lower end of the rotating support block 406 is rotatably connected to the lower surface of the component storage slot 301, and the upper end of the rotating support block 406 is slidably connected to the lower end of the disk 3.

[0031] When the disk 3 is not gripping the workpiece, the height adjustment block 405 is at the lowest point of the inclined end of the trapezoidal slider 404, and the upper end of the rotating support block 406 is tilted outward. When grinding the workpiece, place the workpiece above the disk 3, and firmly install the workpiece on the upper end of the disk 3 by adjusting the suction force of the disk 3. Then adjust the position of the upper grinding wheel. When the grinding wheel is adjusted to the appropriate position, shake the control handle of the saddle 2 to make the saddle 2 drive the disk 3 to move back and forth, so that the grinding wheel can completely grind the surface of the workpiece. At the same time, the moving block and the height adjustment component 4 move back and forth with the saddle 2. If the workpiece needs to be ground to a greater depth during the grinding process, it is not necessary to adjust the position of the upper grinding wheel. Just turn the handle to drive the rotating connecting rod 401 and the screw 402 to rotate simultaneously. Based on the threaded connection between the screw 402 and the screw barrel 403... The screw cylinder 403 and the trapezoidal sliders 404 on both sides move inward simultaneously. Since the height adjustment block 405 cannot move back and forth, during the movement of the trapezoidal slider 404, the lower end of the height adjustment block 405 gradually moves upward from the bottom of the inclined end of the trapezoidal slider 404, causing the disk 3 and the workpiece to move upward simultaneously. At the same time, during the upward movement of the disk 3, the rotating support block 406 will rotate inward in an arc shape, and the rotating support block 406 will gradually become vertical, providing support for the disk 3. During the upward movement of the disk 3, the grinding depth of the workpiece will gradually increase. Under the action of the height adjustment component 4, the grinding depth of the workpiece can be adjusted by adjusting the height position of the disk 3. During the grinding process, the grinding depth of the workpiece can be carefully observed. Compared with the traditional method of adjusting the grinding depth by adjusting the position of the grinding wheel, the operation is simpler and more convenient.

[0032] like Figures 1-4 As shown, a number of connecting blocks 408 are evenly arranged on the outer surface of the rotating connecting rod 401, and a number of connecting grooves 407 are evenly opened on the inner wall of the screw 402, with the connecting blocks 408 inserted into the connecting grooves 407.

[0033] When the connecting rod 401 is rotated by the handle, the connecting rod 401 will drive the screw 402 to rotate due to the engagement of the connecting groove 407 and the connecting block 408. When the saddle 2 drives the disk 3 to move back and forth, the connecting groove 407 moves back and forth simultaneously with the screw 402. The position of the inner end of the connecting block 408 inside the connecting groove 407 changes. Under the action of the connecting groove 407 and the connecting block 408, firstly, the synchronicity of the rotation of the connecting rod 401 and the screw 402 can be ensured, and secondly, the problem of affecting the back and forth movement of the disk 3 can be avoided, thus ensuring the stability of the disk 3 during operation.

[0034] Working principle: When grinding a workpiece, the workpiece is placed above the disk 3. By adjusting the suction force of the disk 3, the workpiece is firmly installed on the upper end of the disk 3. Then, the position of the upper grinding wheel is adjusted. When the grinding wheel is adjusted to the appropriate position, by turning the control handle of the saddle 2, the saddle 2 drives the disk 3 to move back and forth, so that the grinding wheel can completely grind the surface of the workpiece. If the workpiece needs to be ground to a greater depth during the grinding process, it is not necessary to adjust the position of the upper grinding wheel. Simply turn the handle to drive the rotating connecting rod 401. Based on the engagement of the connecting groove 407 and the connecting block 408, rotating the connecting rod 401 will drive the screw 402 to rotate. The screw 402 is threadedly connected to the screw barrel 403, causing the screw barrel 403 and the trapezoidal sliders 404 on both sides to move inward simultaneously. Since the height adjustment block 405 cannot move back and forth, during the movement of the trapezoidal slider 404, the lower end of the height adjustment block 405 gradually moves upward from the bottom of the inclined end of the trapezoidal slider 404, causing the disk 3 and the workpiece to move upward simultaneously. At the same time, during the upward movement of the disk 3, the rotating support block 406 will rotate inward in an arc shape, and the rotating support block 406 will gradually become vertical, providing support for the disk 3. During the upward movement of the disk 3, the grinding depth of the workpiece will gradually increase, achieving the effect of deep grinding.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
