The end of the connecting pipe 16 away from the small water pump 15 is located inside the liquid storage tank. A support frame 20 is provided on the inner wall of the mold base 1.

[0027] To enable the grinding wheel forming machine's forming mold to easily adjust the grinding wheel's processing thickness and to provide rapid cooling and convenient demolding of the grinding wheel, as shown in the attached... Figure 1-5 As shown, this application adopts the following structure: through the coordinated arrangement of a first servo motor 2, an adjusting screw 3, an adjusting frame 4, a guide slide rod 8, a supporting base plate 5, a cavity 7, a drive motor 10, a rotating shaft 11, a connecting spring 13, an impact ball 14, a connecting conduit 16, and a small cooler 17, during use, by controlling the rotation of the first servo motor 2, the adjusting screw 3 is driven to rotate, thereby causing the adjusting frame 4 and the supporting base plate 5 to slide along the guide slide rod 8, adjusting the position of the supporting base plate 5 inside the cavity 7 (the outer surface of the guide slide rod 8 has scale lines), thereby changing the machining thickness of the grinding wheel, adjusting... After the section is completed, the corresponding raw material is added into the cavity 7. Then, the second servo motor 28 rotates, driving the transmission screw 29 to rotate, thereby causing the connecting plate 21, pressure plate 23, and center push rod 26 to move downwards. This allows the center push rod 26 to insert into the center position of the raw material, creating a fixed hole for the grinding wheel, until the center push rod contacts the support base plate 5. As the connecting plate 21 continues to slide down, the center push rod 26 slides relative to the connecting plate 21, stretching the second spring 27. When the pressure plate 23 contacts the raw material, the connecting plate 21 continues to slide down, and the connecting slide rod 22 slides relative to the connecting plate 21, stretching the first spring 24. Under the elastic force of the first spring 24, the pressure plate 23 presses the raw material. When the pressure sensor 25 contacts the connecting plate 21, it sends a pressure signal, stopping the second servo motor 28 from rotating, thus completing the molding process. Next, after the raw material inside the cavity 7 is heated and molded, the small cooler 17 is controlled to work to cool the internal cooling liquid in the storage tank. Subsequently, the small water pump 15 is controlled to operate, delivering the coolant through the connecting pipe 16 to the inside of the cooling tank, and finally returning it to the inside of the storage tank to rapidly cool the cavity 7 and the forming grinding wheel. After the cooling is completed, the drive motor 10 is controlled to rotate. The rotating shaft 11 is driven to rotate, causing the impact ball 14 to intermittently impact the support base plate 5, causing the support base plate 5 to vibrate, thereby causing the forming grinding wheel to vibrate and demold. After completion, the second servo motor 28 is reversed to disengage the connecting plate 21 and the pressure plate 23 from the cavity 7. Then, the first servo motor 2 is rotated to push the support base plate 5 out of the cavity 7, thereby pushing the processed grinding wheel out of the cavity 7 and completing the demolding. This gives the grinding wheel forming machine mold the effect of conveniently adjusting the grinding wheel processing thickness and the effect of rapid cooling and convenient demolding of the grinding wheel.
