Technical Field
[0001] This utility model relates to the field of mold grinding machine technology, specifically a mold grinding machine that is easy to adjust. Background Technology
[0002] A grinding machine is a machine tool that uses abrasives to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives and free abrasives such as oilstones, belt abrasives, honing machines, ultra-precision machining tools, belt grinders, grinding machines, and polishing machines. Grinding machines are needed in the production and processing of molds. However, when grinding molds with ordinary grinding machines, the position of the mold needs to be adjusted manually, which wastes a lot of time and affects the production and grinding efficiency of molds. Therefore, it is necessary to design a mold grinding machine that can be automatically adjusted to improve the production and grinding efficiency of molds.
[0003] A search revealed a mold processing grinding machine disclosed in patent CN219359014U, which includes an operating table. A column is mounted on the top end of the operating table, and a linear motor for vertical movement is mounted on the outer side of the column. A support plate is mounted on the outer side of the linear motor, and a drive motor is mounted on the top end of the support plate. By designing the machine to be placed in a loading hood for clamping and grinding, two first electric push rods can drive the loading hood to move back and forth and left and right. Furthermore, the rotation of the motor shaft can drive the loading hood to rotate. Therefore, when grinding the mold, there is no need for manual adjustment of the mold's position, thereby improving the grinding efficiency and effectively solving the problem of constantly adjusting the mold's position when using a grinding machine.
[0004] However, the mold grinding machine adjustment device in the above technology still has the following problems:
[0005] Although the above technology can move the mold fixed inside the loading hood back and forth and left and right through two electric push rods, and drive the entire loading hood to rotate through the motor shaft, thereby polishing the surface of the mold inside, it can only polish the entire surface of the mold by rotating the loading hood. If the mold has unevenness, it cannot polish the uneven parts, and cannot achieve point-to-point polishing of a certain position of the mold, so its applicability is poor. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an easily adjustable mold grinding machine. For example, the position of the mold to be ground can be moved directly below the grinding mechanism, facilitating targeted grinding of the mold and improving the applicability of the grinding operation.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable mold grinding machine, comprising an operating table and a height-adjustable grinding block mounted on the operating table. Two symmetrically arranged first movable slide grooves are provided on the side of the operating table near the grinding block. The two first movable slide grooves are located on opposite sides of the operating table. A first movable slider is slidably connected within each of the two first movable slide grooves. A support plate is connected to the side of each of the two first movable sliders away from the first movable slide grooves. A support rod is fixedly connected to the side of each support plate away from the operating table. A second movable slide groove is provided on the side of the support rod near the grinding block. A second movable slider is slidably connected within the second movable slide groove. A clamping assembly is connected to the side of the second movable slider away from the second movable slide groove. A first movable assembly is connected to each of the two first movable sliders, and a second movable assembly is connected to the second movable slider.
[0008] Furthermore, the first moving component includes a first lead screw, one end of which is rotatably connected to the inner wall of one end of the first moving groove, and the other end of which passes through the first moving slider and the other end of the first moving groove in sequence, and is threadedly connected to the first moving slider.
[0009] Furthermore, each of the two first lead screws has a transmission gear fixedly connected to one end of the first movable slide groove. A toothed belt is connected between the two transmission gears, and two transmission gears are respectively fitted at both ends of the toothed belt. The toothed belt meshes with the two transmission gears. One of the transmission gears is connected to a first power motor at the end away from the first lead screw. A mounting block is fixedly connected to the housing of the first power motor. The mounting block is fixedly connected to the operating table. The output shaft of the first power motor is fixedly connected to the transmission gear.
[0010] Furthermore, the clamping assembly includes a U-shaped shelf and a threaded rod. The U-shaped shelf is fixedly connected to the side of the second movable slider away from the second movable groove. The opening of the U-shaped shelf faces the side of the grinding block. One end of the threaded rod passes through one side of the U-shaped shelf and is threadedly connected to the U-shaped shelf. A hand-tightening cap is fixedly connected to the end of the threaded rod away from the U-shaped shelf.
[0011] Furthermore, a compression block is fixedly connected to the end of the threaded rod away from the hand-tightening cap.
[0012] Furthermore, the second moving component includes two symmetrically arranged second lead screws. The cross-sections of the second moving slide and the second moving slider are both cross-shaped, and the bottom of the second moving slide is through the slide. The same end of the two second lead screws is rotatably connected to both sides of one end of the second moving slide. The other ends of the two second lead screws pass through both ends of the second moving slider and through the other end of the second moving slide, and are simultaneously connected to the second power component. Both second lead screws are threadedly connected to the second moving slider.
[0013] Furthermore, the second power assembly includes a second power motor, a main gear, and two symmetrically arranged auxiliary gears. The two auxiliary gears are respectively fixedly connected to one end of the two second lead screws that pass through the second moving slide. The main gear meshes with the two auxiliary gears simultaneously. The second power motor is located on the side of the same support plate near the other support plate and is fixedly connected to the support plate. The output shaft of the second power motor passes through the support plate and is fixedly connected to the main gear.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This type of easily adjustable mold grinding machine can move the upper support rod back and forth through two first movable sliders, and can move the clamped mold laterally on the support rod through the second movable slider. The two sliders work together to move any fixed position of the mold to the ground block directly below, which facilitates grinding any fixed position of the mold and improves the operability of mold grinding.

[0021] 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.
[0022] Please see Figure 1 - Figure 4An easily adjustable mold grinding machine includes an operating table 1 and a height-adjustable grinding block 2 mounted on the operating table 1. Two symmetrically arranged first sliding grooves 101 are provided on the side of the operating table 1 closest to the grinding block 2. The two first sliding grooves 101 are located on opposite sides of the operating table 1. First sliding sliders 3 are slidably connected within each of the two first sliding grooves 101. Support plates 4 are connected to the sides of the two first sliding sliders 3 furthest from the first sliding grooves 101. Support rods 5 are fixedly connected to the sides of the two support plates 4 furthest from the operating table 1. A second sliding groove 501 is provided on the side of the support rod 5 closest to the grinding block 2. A second sliding slider 6 is slidably connected within the second sliding groove 501. A clamping assembly is connected to the side of the second sliding slider 6 furthest from the second sliding groove 501. First sliding assemblies are connected to both first sliding sliders 3, and second sliding sliders 6 are connected to the second sliding assembly.
[0023] like Figure 1 - Figure 4 As shown, the adjustable mold grinding machine of this utility model is similar in structure to existing adjustable mold grinding machines, such as the mold processing grinding machine disclosed in patent publication number CN219359014U. The main improvement of this utility model is that the user can move any position of the mold directly under the grinding block 2, facilitating targeted grinding operations on the mold. Figures 1 to 4 As shown, the easily adjustable mold grinding machine of this utility model, when in use, first installs the mold to be ground in the clamping assembly. Then, the second movable slider 6 can slide left and right in the second movable slide groove 501, thereby moving the clamped mold laterally along the second movable slide groove 501 on the support rod 5. When it is necessary to move the clamped mold longitudinally, the first movable slider 3 at the bottom of both ends of the support rod 5 can slide back and forth in the first movable slide groove 101, thereby moving the entire upper support rod 5 back and forth on the operating table 1. In conjunction with the lateral movement of the second movable slider 6, the mold clamped above can be moved to any point on the horizontal plane, so that the upper grinding block 2 can perform grinding operations on any point of the mold. Even if the mold surface is uneven, fixed-point grinding can be performed, improving the applicability of mold grinding operations.
[0024] like Figure 1 and Figure 2As shown, the first moving assembly includes a first lead screw 7. One end of the first lead screw 7 is rotatably connected to the inner wall of one end of the first moving groove 101, and the other end passes through the first moving slider 3 and the other end of the first moving groove 101 in sequence, and is threadedly connected to the first moving slider 3. When the entire support rod 5 moves back and forth, by rotating the two first lead screws 7, the two first moving sliders 3 threadedly connected to them are driven to move back and forth in the two first moving grooves 101, thereby driving the support rod 5 above to move back and forth through the support plate 4. When the two first lead screws 7 drive the two first moving sliders 3 to move, the movement of the two first moving sliders 3 needs to be kept relatively synchronous.
[0025] like Figure 1 and Figure 2 As shown, each of the two first lead screws 7 has a transmission gear 9 fixedly connected to one end of the first movable slide groove 101. A toothed belt 8 is connected between the two transmission gears 9. Two transmission gears 9 are respectively sleeved on both ends of the toothed belt 8. The toothed belt 8 meshes with the two transmission gears 9. One of the transmission gears 9 is connected to a first power motor 10 at the end away from the first lead screw 7. The housing of the first power motor 10 is fixedly connected to a mounting block 11. The mounting block 11 is fixedly connected to the operating table 1. The output shaft of the first power motor 10 is fixedly connected to the transmission gear 9. By starting the first power motor 10, the transmission gear 9 fixed to it is driven to rotate. Then, while driving the first lead screw 7 to rotate, the meshing toothed belt 8 synchronously drives another transmission gear 9 and another first lead screw 7 to rotate, thereby keeping the two first lead screws 7 rotating synchronously and ensuring that the two first moving sliders 3 move synchronously, making the forward and backward movement of the multi-mold more stable. It should be noted that the synchronous rotation between the two first lead screws 7 can be achieved not only through the meshing of the toothed belt 8 and the two transmission gears 9, but also through the chain and chain disc, to ensure that the two first lead screws 7 rotate synchronously.
[0026] like Figure 1 and Figure 2 As shown, the clamping assembly includes a U-shaped plate 12 and a threaded rod 13. The U-shaped plate 12 is fixedly connected to the side of the second movable slider 6 away from the second movable slide groove 501. The opening of the U-shaped plate 12 faces the grinding block 2. One end of the threaded rod 13 passes through one side of the U-shaped plate 12 and is threadedly connected to the U-shaped plate 12. A hand-tightening cap 14 is fixedly connected to the end of the threaded rod 13 away from the U-shaped plate 12. When using the clamping assembly to clamp and fix the mold to be processed, first, the threaded rod 13 is turned outwards through the hand-tightening cap 14. Then, the mold is placed inside the U-shaped plate 12. At this time, the threaded rod 13 can be turned again through the hand-tightening cap 14, so that the threaded rod 13 gradually moves into the U-shaped plate 12 and finally clamps and fixes the mold. The operation and installation method is simple and quick.
[0027] like Figure 1 and Figure 2 As shown, a pressing block 15 is fixedly connected to the end of the threaded rod 13 away from the hand-tightening cap 14. When the threaded rod 13 is tightened and clamped to the mold by the hand-tightening cap 14, the design of the pressing block 15 can prevent the threaded rod 13 from directly pressing the mold surface, reducing the extrusion wear on the mold clamping and fixing. The pressing block 15 can be a rubber block, which can reduce the possible extrusion damage to the mold when it comes into contact with the mold. At the same time, the rubber block can increase the friction when it comes into contact with the mold, further improving the firmness of the clamping and fixing of the mold.
[0028] like Figure 1 - Figure 4 As shown, the second moving component includes two symmetrically arranged second lead screws 16. The cross-sections of the second moving groove 501 and the second moving slider 6 are both cross-shaped, and the bottom of the second moving groove (501) is through-hole. The same end of the two second lead screws 16 is rotatably connected to both sides of one end of the second moving groove 501, and the other end of the two second lead screws 16 passes through both ends of the second moving slider 6 and through the other end of the second moving groove 501, and is simultaneously connected to a second power component. Both second lead screws 16 are threadedly connected to the second moving slider 6. When the clamped mold is moved laterally left and right, the rotation of the two second lead screws 16 drives the second moving slider 6, which is threadedly connected to them, to slide left and right in the second moving groove 501, thereby causing the mold clamped in the U-shaped shelf 12 above to move laterally left and right. When the two second lead screws 16 rotate, the transmission direction of the second moving slider 6 needs to be consistent to ensure that the second moving slider 6 can be smoothly moved when the two second lead screws 16 rotate.
[0029] like Figure 1 - Figure 4 As shown, the second power assembly includes a second power motor 17, a main gear 18, and two symmetrically arranged auxiliary gears 19. The two auxiliary gears 19 are fixedly connected to one end of each of the two second lead screws 16, which pass through the second moving slide groove 501. The main gear 18 meshes with both auxiliary gears 19 simultaneously. The second power motor 17 is located on the side of the same support plate 4 near the other support plate 4 and is fixedly connected to the support plate 4. The output shaft of the second power motor 17 passes through the support plate 4 and is fixedly connected to the main gear 18. When the second moving slider 6 is moved, the second power motor 17 is activated, passing through the support plate 4 and driving the main gear 18 to rotate. When the main gear 18 rotates, it simultaneously drives the two meshing auxiliary gears 19 to rotate, causing the two auxiliary gears 19 to rotate simultaneously either counterclockwise or clockwise, thus ensuring that the two second lead screws 16 rotate synchronously. The two auxiliary gears 19 must be of the same size, and the main gear 18 is located at the center line of the two auxiliary gears 19.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
