[0026] As shown in Figure 1 and Figure 2 A resin cup-shaped grinding wheel mold, as shown in the drawings, comprises a mold sleeve 1, which is a hollow cylindrical shell, and a bottom plate 2 mounted at one end of the mold sleeve 1 to block the opening at one end of the mold sleeve 1.

[0027] A bottom edge pressing assembly or an edge pressing assembly is mounted in the mold sleeve 1. The bottom edge pressing assembly comprises a pressing pad 7 and a first pressing plate 8, which cooperate with the mold sleeve 1 and the bottom plate 2 to press the reinforcing layer 91 of the cup-shaped grinding wheel 9. The edge pressing assembly comprises a second pressing plate 4 and a center sleeve 5, which cooperate with the mold sleeve 1 and the bottom plate 2 to press the edge 92 of the cup-shaped grinding wheel 9.

[0028] The bottom plate 2 is provided with a fixing member 21 for fixing an embedded nut 3. The embedded nut 3 and the fixing member 21 are both provided with threads and are screwed together. The embedded nut 3 is embedded in the bottom of the cup-shaped grinding wheel 9 and is used to ensure the stability of the grinding wheel during use when the grinding wheel is mounted on a grinding device.

[0029] The inner nut 3 is provided with a nut positioning member 31, which is integrally connected with the inner nut 3, and is used for axial positioning of the inner nut 3 to prevent the inner nut 3 from falling out of the cup-shaped grinding wheel 9 during long-term use.

[0030] One end of the mandrel 6 is provided with a threaded hole 61, and the other end is provided with a positioning hole 62. The end of the mandrel 6 with the threaded hole 61 is installed on the fixing member 21 and is in screw connection with the fixing member 21, and is located at the upper end of the inner nut 3 and abuts against the upper end surface of the inner nut 3.

[0031] During the manufacturing process of the cup-shaped grinding wheel 9, the reinforcing layer 91 needs to be manufactured first. During the manufacturing of the reinforcing layer 91, the bottom pressing assembly is used. The resin material used for manufacturing the reinforcing layer 91 is poured into the bottom of the mold sleeve 1 to a predetermined height. The first pressing plate 8 is sleeved on the mandrel 6, and the first pressing plate 8 is in sliding connection with the mold sleeve 1 and the mandrel 6. The first pressing plate 8 abuts against the reinforcing layer 91 and presses the reinforcing layer 91. The pressure pad 7 is installed above the first pressing plate 8, and the pressure pad 7 is sleeved on the mandrel 6. The pressure pad 7 is used to apply pressure to the first pressing plate 8 to compact the reinforcing layer 91 and ensure that it is uniformly distributed and closely attached to the wall of the mold sleeve 1.

[0032] After the reinforcing layer 91 is manufactured, the pressure pad 7 and the first pressing plate 8 are removed, and then the edge part 92 is manufactured. The center sleeve 5 is sleeved on the mandrel 6 and located at the upper end of the inner nut 3, and is in sliding connection with the mandrel 6 and abuts against the reinforcing layer 91. Resin material is continuously added to the mold sleeve 1 to a predetermined height. The resin material of the edge part 92 is fully combined with the reinforcing layer 91 to form a whole. The second pressing plate 4 is sleeved on the center sleeve 5 and is in sliding connection with the center sleeve 5 and the mold sleeve 1. The second pressing plate 4 abuts against the edge part 92. Uniform pressure is applied to the top of the second pressing plate 4 to make the resin material of the edge part 92 closely attached to the wall of the mold sleeve 1. Wait for the resin material to completely solidify to finally form the cup-shaped grinding wheel 9.

[0033] The center sleeve 5 is fixed with a dismounting pad 51 provided with threads. The screw rod 10 is in screw connection with the dismounting pad 51. The screw rod 10 abuts against the positioning hole 62 to facilitate positioning of the screw rod 10 and facilitate removal of the center sleeve 5. The screw rod 10 is provided with a handle and is used to remove the center sleeve 5. After the cup-shaped grinding wheel 9 is manufactured, the screw rod 10 with the handle is used to slowly pull out the center sleeve 5 through screwing motion. Then the second pressing plate 4, the mandrel 6 and the bottom plate 2 are removed in sequence, and finally the cup-shaped grinding wheel 9 is removed.

[0034] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
