[0024] Combined with attachment Figure 1 and attached Figure 2 A grinding device for mold production and manufacturing includes a base plate 1, on which a grinding motor 2 that is easy to disassemble and assemble is provided. A fixed plate 3 is provided at the top of the base plate 1, and a rotating shaft 4 that is rotatably connected and driven by the grinding motor 2 is plugged into the fixed plate 3. A grinding disc 5 is provided at one end of the rotating shaft 4.

[0025] Through the above structure, the grinding motor 2 drives the rotating shaft 4 to rotate continuously, and the grinding sheet 5 located on the rotating shaft 4 rotates accordingly, so that the mold can be directly ground.

[0026] Combined with attachment Figure 1 and attached Figure 3 An arc-shaped placement rack 6 is provided on one side of the top of the base plate 1, and an arc-shaped fixing rack 7 is provided on one side of the top of the arc-shaped placement rack 6, which is rotatably connected and used in conjunction with the arc-shaped placement rack 6. The grinding motor 2 is placed in the arc-shaped groove of the arc-shaped placement rack 6 and the arc-shaped fixing rack 7, and a locking structure is provided between the arc-shaped placement rack 6 and the arc-shaped fixing rack 7.

[0027] Through the above structure, the grinding motor 2 is placed in the arc groove of the arc placement frame 6 and the arc fixing frame 7, and the arc placement frame 6 and the arc fixing frame 7 are fixed together through the locking structure, so the overall stability is high.

[0028] Combined with attachment Figure 3 and attached Figure 4The locking structure includes an insertion slot 8 arranged on one side of the arc-shaped placement frame 6 and the arc-shaped fixing frame 7. The top of the base plate 1 is provided with a limiting column 9 passing through the insertion slot 8. The top of the limiting column 9 is provided with a double nut 10 with a threaded connection, and the thread directions of the double nut 10 are opposite.

[0029] Through the above structure, the arc-shaped fixing frame 7 is directly clamped on the arc-shaped placing frame 6. At this time, the arc-shaped placing frame 6 and the arc-shaped fixing frame 7 are fitted together, and the limiting column 9 is located in the insertion groove 8. When the double nut 10 is screwed on, the arc-shaped placing frame 6 and the arc-shaped fixing frame 7 can be locked and fixed together. Moreover, the thread directions of the double nut 10 are opposite, and the overall stability is high.

[0030] Example 2

[0031] Combined with attachment Figure 2 and attached Figure 5 A collection box 11 is provided on one side of the top of the base plate 1, and a groove 12 is provided on one side of the collection box 11. The grinding sheet 5 extends into the groove 12. A slide groove 13 is provided on the top of the base plate 1, and a sliding block 14 is provided in the slide groove 13. A vertical plate 15 is provided on the top of the slider 14 for rotation connection. An arc-shaped plate 16 is provided on one side of the vertical plate 15, and an arc groove 17 is provided on the arc plate 16. A stud 18 passing through the arc groove 17 is provided on one side of the top of the slider 14, and a locking knob 19 is provided on the top of the stud 18.

[0032] Through the above structure, the mold to be polished is placed on the slider 14 so that one side of the mold is close to the vertical plate 15. With the assistance of the slider 14 and the slide groove 13, it can move smoothly horizontally to ensure that the mold is evenly polished with high polishing accuracy. When adjustment is needed, loosen the locking knob 19 and rotate the vertical plate 15. At this time, the stud 18 moves in the arc groove 17. When the vertical plate 15 is to a suitable inclination angle, the locking knob 19 is continuously moved down until it is against the arc plate 16, and the arc plate 16 and the vertical plate 15 are locked and fixed, which is convenient for multi-angle polishing of molds of different shapes, convenient adjustment, and saves time and effort.

[0033] Combined with attachment Figure 1 and attached Figure 5 The arc plate 16 is provided with an angle scale line 20 used in conjunction with the arc groove 17, and one side of the collection box 11 is provided with a box door 21 that is rotatably connected.

[0034] Through the above structure, the angle scale line 20 can be used to check the inclination angle of the vertical plate 15, which is convenient for precise grinding and high grinding quality. In addition, the debris generated by grinding is uniformly collected in the collection box 11. By opening the box door 21, the debris can be uniformly processed and dumped, which is convenient to use.

[0035] When the utility model is implemented:

[0036] First, place the grinding motor 2 directly in the arc groove on the arc placement frame 6, then connect the grinding motor 2 and the rotating shaft 4 together, and then rotate the arc placement frame 6 so that the arc placement frame 6 and the arc fixing frame 7 fit together to clamp the grinding motor 2. The limit column 9 is located in the insertion groove 8, and then the double nut 10 is screwed on to lock the arc placement frame 6 and the arc fixing frame 7 together. The thread directions of the double nuts 10 are opposite, and the overall stability is high. At the same time, it is convenient for disassembly and assembly, and convenient for later maintenance and replacement.

[0037] Then place the mold to be polished directly on the top of the collection box 11, so that one side of the mold fits tightly against the vertical plate 15. With the assistance of the slider 14 and the slide 13, it can move smoothly laterally to ensure that the mold is polished evenly and with high polishing accuracy.

[0038] When multi-angle grinding is required, loosen the locking knob 19 and rotate the vertical plate 15. At this time, the stud 18 moves in the arc groove 17. When the vertical plate 15 is at a suitable inclination angle, the locking knob 19 is continuously moved down until it contacts the arc plate 16, and the arc plate 16 and the vertical plate 15 are locked and fixed, which is convenient for multi-angle grinding of molds of different shapes, easy to adjust, and saves time and effort.
