[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-4 As shown, this utility model provides a grinding device for injection mold processing, including a grinding table 1. An L-shaped frame 11 is fixedly installed on the upper surface of the grinding table 1. An equipment plate 12 is fixedly installed at one end of the L-shaped frame 11. Two cylinders 13 are fixedly installed on the upper surface of the grinding table 1. A clamping block 14 is fixedly installed on the piston end of each of the two cylinders 13. By setting the cylinders 13 and clamping blocks 14, when the injection mold 10 to be ground is placed between the two clamping blocks 14, the piston of the cylinder 13 can push the clamping block 14 to move horizontally. The injection mold 10 is clamped by the clamping block 14. The equipment plate 12 is equipped with a grinding component 2. The grinding component 2 is equipped with a horizontal adjustment component 3 and an angle adjustment component 4. By setting the grinding component 2, the horizontal adjustment component 3 and the angle adjustment component 4, the grinding component 2 can grind the protruding part of the injection mold 10, the horizontal adjustment component 3 can adjust the horizontal position of the grinding machine 22, and the angle adjustment component 4 can adjust the angle of the grinding machine 22 so that the grinding roller of the grinding machine 22 grinds the edge of the protruding part of the injection mold 10.

[0026] The grinding assembly 2 includes a U-shaped base 21, within which a grinding machine 22 is housed. A rotating rod 23 is rotatably mounted at the axis of the equipment disc 12. A connecting handle 24 is fixedly mounted at one end of the rotating rod 23, and a connecting rod 25 is fixedly mounted at one end of the connecting handle 24. A fixing frame 26 is fixedly mounted at one end of the connecting rod 25, and a fixing plate 27 is fixedly mounted on the lower surface of the fixing frame 26. The U-shaped base 21 and the grinding machine 22 are slidably disposed on the lower surface of the fixing plate 27. By driving the rotating rod 23 to rotate, the rotating rod 23 can pass through the connecting handle 24, the connecting rod 25, and the fixing plate 26. The fixed frame 26 and the fixed plate 27 cause the U-shaped seat 21 and the grinder 22 to revolve in a circle. During the revolve, the grinder 22 grinds the edge of the protruding part of the injection mold 10. The upper surface of the equipment plate 12 is fixedly equipped with a motor 28. The end of the rotating rod 23 away from the connecting handle 24 is fixedly connected to the drive output end of the motor 28. By turning on the motor 28, the drive shaft of the motor 28 can make the rotating rod 23 rotate. The fixed end of the motor 28 is fixedly installed with an L-shaped mounting bracket 29. One end of the L-shaped mounting bracket 29 is fixedly connected to the upper surface of the equipment plate 12.

[0027] The horizontal adjustment assembly 3 includes a drive plate 31, one end of which is fixedly connected to the upper surface of the U-shaped seat 21. A lead screw 32 is rotatably mounted on the lower surface of the fixed plate 27. The lead screw 32 passes through the drive plate 31 and is threadedly connected to the drive plate 31. By rotating the lead screw 32, the drive plate 31 can be moved horizontally, and the drive plate 31 can move the U-shaped seat 21 and the grinder 22 horizontally. Two support plates 33 are fixedly mounted on the lower surface of the fixed plate 27. The end of the lead screw 32 is rotatably connected to the two support plates 33. A first rotating wheel 34 is fixedly mounted on one end of the lead screw 32. By setting the first rotating wheel 34, it is convenient for the operator to rotate the lead screw 32.

[0028] A guide groove 35 is provided on the fixed plate 27. A guide block 36 is slidably installed in the middle of the guide groove 35. The other end of the drive plate 31 is fixedly connected to the lower surface of the guide block 36. By setting the guide groove 35 and the guide block 36, the guide block 36 can slide horizontally in the guide groove 35, thereby guiding the drive plate 31 in the horizontal direction and keeping the drive plate 31 moving in the horizontal direction.

[0029] The angle adjustment assembly 4 includes a rotating shaft 41, which is rotatably connected to a U-shaped seat 21. The grinder 22 is fixedly mounted on the rotating shaft 41. A U-shaped sleeve 42 is fixedly mounted on one side of the U-shaped seat 21. A worm gear 43 is rotatably mounted on the U-shaped sleeve 42. A worm wheel 44 is fixedly mounted on one end of the rotating shaft 41. The worm gear 43 and the worm wheel 44 are meshed together. By rotating the worm gear 43, the worm gear 43 can cause the worm wheel 44 to rotate, which in turn causes the rotating shaft 41 to rotate. The rotating shaft 41 can cause the grinder 22 to rotate around the axis of the rotating shaft 41, so that the grinding roller of the grinder 22 is in contact with the edge of the protruding part of the injection mold 10. A second rotating wheel 45 is fixedly mounted on one end of the worm gear 43. By setting the second rotating wheel 45, it is convenient for the operator to rotate the worm gear 43.

[0030] Working principle: When it is necessary to grind the edge of the protruding part of the injection mold 10, the operator first places the injection mold 10 between two clamping blocks 14, and then simultaneously opens two cylinders 13. The piston ends of the two cylinders 13 bring the two clamping blocks 14 closer to each other, and clamp the injection mold 10 through the two clamping blocks 14.

[0031] Subsequently, the operator manually rotates the first rotating wheel 34, which causes the lead screw 32 to rotate. The lead screw 32 causes the drive plate 31 to move horizontally. The drive plate 31 causes the U-shaped seat 21 and the grinding machine 22 to move horizontally synchronously. At the same time, the operator manually rotates the second rotating wheel 45, which causes the worm gear 43 to rotate. The worm gear 43 causes the worm wheel 44 to rotate. The worm wheel 44 causes the rotating shaft 41 to rotate. The rotating shaft 41 causes the grinding machine 22 to rotate around the axis of the rotating shaft 41, so that the grinding roller of the grinding machine 22 contacts the edge of the protruding part of the injection mold 10.

[0032] Finally, the operator simultaneously turns on the motor 28 and the grinder 22. The drive shaft of the motor 28 causes the rotating rod 23 to rotate. The rotating rod 23, through the connecting handle 24, connecting rod 25, fixing frame 26 and fixing plate 27, causes the U-shaped seat 21 and the grinder 22 to revolve in a circle. During the revolve, the grinding roller at the end of the grinder 22 grinds the edge of the protruding part of the injection mold 10, thus conveniently realizing the grinding of the edge of the protruding part of the injection mold 10, thereby effectively improving the convenience and efficiency of grinding the protruding part of the injection mold 10.
