Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grinding wheel production technology, and in particular relates to a mold for grinding wheel production. Background Technology
[0002] A grinding wheel is a tool made of abrasive and bonding agent through a specific process for grinding, lapping and polishing. In the machinery manufacturing industry, it is used to grind various metal parts, such as shafts, gears, threads, etc., to improve the dimensional accuracy and surface quality of the parts. It can also be used to sharpen various cutting tools, such as lathe tools, milling cutters, drill bits, etc., to keep them sharp cutting edges.
[0003] In the production of common grinding wheels, the raw material is typically extruded into shape using a mold. However, after extrusion, conventional molds make it difficult for personnel to remove the formed grinding wheels, and the wheels are easily damaged during removal. Furthermore, common molds can only extrude grinding wheels of the same size; when different sizes need to be produced, the entire mold must be replaced, which is cumbersome. Therefore, we propose a new type of mold for grinding wheel production. Utility Model Content
[0004] The purpose of this utility model is to provide a mold for grinding wheel production to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a mold for producing grinding wheels, comprising:
[0006] The outer shell has an extrusion groove on its top, and several limiting rings are provided in the extrusion groove. The top of each of the limiting rings is engraved with scale lines. Rotating rods are rotatably installed on the top of the outer shell and on both sides of the limiting rings. A threaded rod is threaded onto the rotating rod. The bottom end of the threaded rod passes through the top of the rotating rod and is rotatably installed with an extrusion plate. A rubber pad is fixedly installed at the bottom of the extrusion plate. A knob is fixedly installed at the top of the threaded rod.
[0007] A sliding groove is formed inside the outer shell and located below the extrusion groove. A movable frame is slidably installed inside the sliding groove. Several sliding rods are fixedly installed on the top of the movable frame and inside the sliding groove. The top ends of the several sliding rods all penetrate the top of the sliding groove and extend into the extrusion groove.
[0008] A drive assembly, located inside the housing, is used to drive the moving frame to move up and down.
[0009] In this technical solution, during use, the operator can first put the raw material of the grinding wheel into the extrusion groove, and then extrude the raw material through a press. At this time, under the limiting action of the limiting ring, the raw material can be extruded into shape. After extrusion, the operator can drive the moving frame and one of the sliding rods to move upward through the drive component. At the same time, the upward movement of the moving frame will also drive the remaining sliding rods to move upward. The upward movement of several sliding rods will extrude the formed grinding wheel and squeeze it out of the extrusion groove. Since the several sliding rods are evenly distributed, it is ensured that the grinding wheel is not deformed by extrusion, and it is easy for the operator to take out the formed grinding wheel from the extrusion groove without damaging the newly formed grinding wheel.
[0010] When producing grinding wheels with larger diameters, the operator first rotates both knobs. Rotating knob one rotates the threaded rod one, which in turn moves the extrusion plate upwards until the rubber pad at the bottom of the extrusion plate moves out from the top of the retaining rings. Then, the operator rotates the rotating rod to move the extrusion plate to the periphery of the retaining rings. At this point, the two extrusion plates can release their restraints from several graduation lines. The operator can observe these graduation lines and remove an appropriate number of retaining rings sequentially from the inside out until the inner diameter of the innermost retaining ring reaches the desired size. Then, the two rotating rods are rotated again, moving the extrusion plate to the top of the remaining retaining rings. Rotating knob one again rotates the threaded rod one, which in turn moves the extrusion plate downwards until the rubber pad at the bottom of the extrusion plate presses against the top of the remaining retaining rings. At this point, the two extrusion plates restrain the remaining retaining rings, ensuring that the operator can easily change the inner diameter of the extrusion groove, thus producing grinding wheels of different sizes.
[0011] In the above technical solution, the driving component further includes:
[0012] A rotating groove is formed inside the outer casing and located below the sliding groove. A bevel gear one is rotatably mounted on the top of the rotating groove. The top end of the bevel gear one extends through the top of the rotating groove into the sliding groove and is fixedly mounted with a threaded rod two. The top end of the threaded rod two extends through the movable frame and into one of the sliding rods. A bevel gear two is meshed on one side of the bevel gear one and located in the rotating groove. One end of the bevel gear two extends through one side of the rotating groove to the outside and is fixedly mounted with a knob two.
[0013] In this technical solution, rotating knob two causes bevel gear two to rotate. Under the action of meshing, the rotation of bevel gear two causes bevel gear one to rotate. The rotation of bevel gear one causes threaded rod two to rotate. Under the action of the thread, the rotation of threaded rod two causes the moving frame and one of the sliding rods to move upward. At the same time, the upward movement of the moving frame also causes the remaining sliding rods to move upward. The upward movement of several sliding rods will compress the formed grinding wheel, which can squeeze the grinding wheel out of the extrusion groove. Since the several sliding rods are evenly distributed, it is ensured that the grinding wheel is not deformed by extrusion, so that it is easy for personnel to remove the formed grinding wheel from the extrusion groove without damaging the newly formed grinding wheel.
[0014] In the above technical solution, the threaded rod two is rotatably connected to the sliding groove, the threaded rod two is threadedly connected to the moving frame and one of the sliding rods, and the bevel gear two is rotatably connected to the rotating groove.
[0015] In this technical solution, it is ensured that the second threaded rod can rotate normally in the sliding groove, that the rotation of the second threaded rod can drive the moving frame and one of the sliding rods to move up and down, and that the second bevel gear can rotate normally in the rotating groove.
[0016] Furthermore, the above technical solution also includes:
[0017] Two handles are symmetrically fixedly installed on the periphery of the housing.
[0018] In this technical solution, it is ensured that personnel can move the entire device by holding two handles.
[0019] In the above technical solution, further, the diameter of the plurality of limiting rings increases sequentially from the inside to the outside, and the top of the plurality of limiting rings is located on the same horizontal plane as the top of the outer shell.
[0020] In this technical solution, it is ensured that grinding wheels of different sizes can be produced, and the structural stability of several limit rings and the outer shell is guaranteed.
[0021] In the above technical solution, furthermore, the top ends of several sliding rods and the bottom of the extrusion groove are located on the same horizontal plane, and the cross-section of the rotating rod is L-shaped.
[0022] In this technical solution, the structural stability of several sliding rods is ensured, and the structural stability of the rotating rod is guaranteed.
[0023] In the above technical solution, the sliding rod is further slidably connected to the sliding groove.
[0024] In this technical solution, it is ensured that the sliding rod can slide normally within the sliding groove.
[0025] The beneficial effects of this utility model are:
[0026] 1. The mold for producing grinding wheels, through the setting of the extrusion groove, and with the cooperation of the extrusion groove, several limit rings, drive components, moving frame and several sliding rods, ensures that the grinding wheel is not deformed by extrusion, and that it is easy for personnel to take out the formed grinding wheel from the extrusion groove without damaging the newly formed grinding wheel.
[0027] 2. The mold for producing grinding wheels, through the combination of two knobs, two threaded rods, two extrusion plates, two rubber pads, several scale lines, and several limit rings, ensures that personnel can easily change the inner diameter of the extrusion groove, thereby producing grinding wheels of different sizes.

[0041] Please see Figure 1 - Figure 6 As shown, this embodiment provides a mold for producing grinding wheels, including:
[0042] The outer shell 1 has an extrusion groove 2 on its top. Several limiting rings 3 are provided in the extrusion groove 2. The top of each of the limiting rings 3 is engraved with scale lines 4. Rotating rods 5 are rotatably installed on the top of the outer shell 1 and on both sides of the limiting rings 3. A threaded rod 6 is threaded on the rotating rod 5. The bottom end of the threaded rod 6 passes through the top of the rotating rod 5 and is rotatably installed with an extrusion plate 8. A rubber pad 9 is fixedly installed at the bottom of the extrusion plate 8. A knob 7 is fixedly installed at the top of the threaded rod 6.
[0043] The sliding groove 10 is opened inside the outer shell 1 and located below the extrusion groove 2. A movable frame 11 is slidably installed inside the sliding groove 10. Several sliding rods 12 are fixedly installed on the top of the movable frame 11 and inside the sliding groove 10. The top ends of the several sliding rods 12 all pass through the top of the sliding groove 10 and extend into the extrusion groove 2.
[0044] The drive assembly is located inside the housing 1 and is used to drive the moving frame 11 to move up and down.
[0045] In use, the operator can first put the raw material of the grinding wheel into the extrusion groove 2, and then extrude the raw material by the press. At this time, under the limiting action of the limiting ring 3, the raw material can be extruded into shape. After extrusion, the operator can drive the moving frame 11 and one of the sliding rods 12 to move upward by the drive component. At the same time, the upward movement of the moving frame 11 will also drive the remaining sliding rods 12 to move upward. The upward movement of several sliding rods 12 will extrude the formed grinding wheel and squeeze it out of the extrusion groove 2. Since the several sliding rods 12 are distributed relatively evenly, it is ensured that the grinding wheel is not deformed by extrusion, and it is easy for the operator to take out the formed grinding wheel from the extrusion groove 2 without damaging the newly formed grinding wheel.
[0046] When producing grinding wheels with larger diameters, the operator can first rotate both knobs 7. Rotating knobs 7 will cause the threaded rod 6 to rotate. Under the action of the thread, the rotation of the threaded rod 6 will move the extrusion plate 8 upwards until the rubber pad 9 at the bottom of the extrusion plate 8 moves out from the top of the retaining rings 3. Then, the operator can rotate the rotating rod 5 to move the extrusion plate 8 to the periphery of the retaining rings 3. At this point, the two extrusion plates 8 can release their restraints from the graduation lines 4. The operator can then observe the graduation lines 4 and remove an appropriate number of retaining rings 3 sequentially from the inside out until... Once the inner diameter of the innermost limiting ring 3 reaches the appropriate size, rotate the two rotating rods 5. Rotating the rotating rods 5 will move the extrusion plate 8 to the top of the remaining limiting ring 3. Then rotate the knob 7 again. Rotating the knob 7 will drive the threaded rod 6 to rotate. Under the action of the thread, the rotation of the threaded rod 6 will drive the extrusion plate 8 to move downward until the rubber pad 9 at the bottom of the extrusion plate 8 is pressed against the top of the remaining limiting ring 3. At this time, the two extrusion plates 8 can limit the remaining limiting ring 3, ensuring that it is easy for personnel to change the inner diameter of the extrusion groove 2, thereby producing grinding wheels of different sizes. Example
[0047] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a driving component:
[0048] A rotating groove 13 is formed inside the outer casing 1 and located below the sliding groove 10. A bevel gear 15 is rotatably mounted on the top of the rotating groove 13. The top end of the bevel gear 15 extends through the top of the rotating groove 13 into the sliding groove 10 and is fixedly mounted with a threaded rod 14. The top end of the threaded rod 14 extends through the movable frame 11 and into one of the sliding rods 12. A bevel gear 16 is meshed with one side of the bevel gear 15 and located in the rotating groove 13. One end of the bevel gear 16 extends through one side of the rotating groove 13 to the outside and is fixedly mounted with a knob 17.
[0049] Rotating knob 17 causes bevel gear 16 to rotate. Under meshing action, bevel gear 16 rotates bevel gear 15, which in turn rotates threaded rod 14. The threaded rod 14 rotates, causing the moving frame 11 and one of the sliding rods 12 to move upwards. Simultaneously, the upward movement of the moving frame 11 also causes the remaining sliding rods 12 to move upwards. The upward movement of the sliding rods 12 compresses the formed grinding wheel, extruding it from the extrusion groove 2. Because the sliding rods 12 are evenly distributed, deformation of the grinding wheel is avoided, ensuring easy removal of the formed grinding wheel from the extrusion groove 2 without damage. Example
[0050] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threaded rod 14 is rotatably connected to the sliding groove 10, the threaded rod 14 is threadedly connected to the moving frame 11 and one of the sliding rods 12, and the bevel gear 16 is rotatably connected to the rotating groove 13.
[0051] Specifically, it ensures that the threaded rod 14 can rotate normally in the sliding groove 10, that the rotation of the threaded rod 14 can drive the moving frame 11 and one of the sliding rods 12 to move up and down, and that the bevel gear 16 can rotate normally in the rotating groove 13. Example
[0052] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features, and further includes:

[0054] This ensures that personnel can move the entire device by holding two handles (18). Example
[0055] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features: the diameter of a plurality of limiting rings 3 increases sequentially from the inside to the outside, and the top of the plurality of limiting rings 3 is located on the same horizontal plane as the top of the outer shell 1.
[0056] This ensures that grinding wheels of different sizes can be produced, and guarantees the structural stability of several limit rings 3 and the outer shell 1. Example
[0057] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features: the tops of several sliding rods 12 are located on the same horizontal plane as the bottom of the extrusion groove 2, and the cross-section of the rotating rod 5 is L-shaped.
[0058] This ensures the structural stability of several sliding rods 12 and guarantees the structural stability of the rotating rod 5. Example
[0059] This embodiment provides a mold for producing grinding wheels. In addition to the technical solutions of the above embodiments, it also has the following technical features: the sliding rod 12 is slidably connected to the sliding groove 10.
[0060] This ensures that the sliding rod 12 can slide normally within the sliding groove 10.
[0061] Working principle: In use, the operator can first put the raw material of the grinding wheel into the extrusion groove 2, and then extrude the raw material through the press. At this time, under the limiting action of the limiting ring 3, the raw material can be extruded into shape. After extrusion, the operator can turn the knob 17. The rotation of the knob 17 will drive the bevel gear 16 to rotate. Under the meshing action, the rotation of the bevel gear 16 will drive the rotation of the bevel gear 15. The rotation of the bevel gear 15 will drive the threaded rod 14 to rotate. Under the action of the thread, the rotation of the threaded rod 14 will drive the moving frame 11 and one of the sliding rods 12 to move upward. At the same time, the upward movement of the moving frame 11 will also drive the remaining sliding rods 12 to move upward. The upward movement of several sliding rods 12 will extrude the formed grinding wheel and squeeze it out of the extrusion groove 2. Since the several sliding rods 12 are evenly distributed, it is ensured that the grinding wheel is not deformed by extrusion, and it is easy for the operator to take out the formed grinding wheel from the extrusion groove 2 without damaging the newly formed grinding wheel.
[0062] When producing grinding wheels with larger diameters, the operator can first rotate both knobs 7. Rotating knobs 7 will cause the threaded rod 6 to rotate. Under the action of the thread, the rotation of the threaded rod 6 will move the extrusion plate 8 upwards until the rubber pad 9 at the bottom of the extrusion plate 8 moves out from the top of the retaining rings 3. Then, the operator can rotate the rotating rod 5 to move the extrusion plate 8 to the periphery of the retaining rings 3. At this point, the two extrusion plates 8 can release their restraints from the graduation lines 4. The operator can then observe the graduation lines 4 and remove an appropriate number of retaining rings 3 sequentially from the inside out until... Once the inner diameter of the innermost limiting ring 3 reaches the appropriate size, rotate the two rotating rods 5. Rotating the rotating rods 5 will move the extrusion plate 8 to the top of the remaining limiting ring 3. Then rotate the knob 7 again. Rotating the knob 7 will drive the threaded rod 6 to rotate. Under the action of the thread, the rotation of the threaded rod 6 will drive the extrusion plate 8 to move downward until the rubber pad 9 at the bottom of the extrusion plate 8 is pressed against the top of the remaining limiting ring 3. At this time, the two extrusion plates 8 can limit the remaining limiting ring 3, ensuring that it is easy for personnel to change the inner diameter of the extrusion groove 2, thereby producing grinding wheels of different sizes.
