[0029] Embodiment

[0030] As Figure 1 、 2 、3, and 4 show, a polishing device for mold production and processing, including a polishing processing execution end 10, the polishing processing execution end 10 includes a fixed horizontal plate 11, a cylindrical connecting block 12 is provided at the bottom of the fixed horizontal plate 11, a linkage component 13 is provided at the bottom inner wall of the cylindrical connecting block 12, the linkage component 13 includes an annular internal gear 131 on the inner wall of the annular groove 121, an inner ring of the annular internal gear 131 is meshed and connected with a driven gear set 132, and the driven gear set 132 is meshed and connected with a driving gear 133; the execution end of the driving motor 16 is connected to the top of the driving gear 133;

[0031] It should be noted that, in this embodiment, when the execution end of the driving motor 16 provided on the inner wall of the fixed horizontal plate 11 works, it drives the driving gear 133 connected to its execution end to rotate. Among them, the driving gear 133 is meshed and connected with the driven gear set 132. When the driving gear 133 rotates, it drives the driven gear set 132 to rotate together,

[0032] Furthermore, the annular internal gear 131 is embedded in the annular groove 121 at the bottom of the cylindrical connecting block 12, and the annular internal gear 131 is meshed and connected with the driven gear set 132. Therefore, the driven gear set 132 realizes continuous circular motion in the inner cavity of the cylindrical connecting block 12, and at the same time, the driven gear set 132 itself also rotates continuously.

[0033] As shown Figure 2 in 3 Figures 4 and 5, an annular groove 121 is embedded at the bottom of the inner wall of the cylindrical connection block 12. The linkage assembly 13 includes an annular internal gear 131 on the inner wall of the annular groove 121. A driven gear set 132 is meshed and connected to the inner ring of the annular internal gear 131. The driven gear set 132 is meshed and connected to a driving gear 133. The driven gear set 132 has at least two gears; the gears in the driven gear set 132 are not meshed with each other, and are simultaneously meshed and connected to the annular internal gear 131 and the driving gear 133; the depth of the annular groove 121 is greater than the radius of the addendum circle of the annular internal gear 131; a polishing tool 134 is provided at the bottom of the driven gear set 132, and the number of the polishing tools 134 is the same as the number of gears provided in the driven gear set 132.

[0034] It should be noted that in this embodiment, the bottom of the driven gear set 132 is connected to the bottom of the gear in the polishing tool 134. In summary, it is realized that while the polishing tool 134 rotates itself, it makes a circular motion centered on the driving gear 133. Through the dual rotation, the polishing efficiency of the polishing tool 134 is faster than the traditional method during the polishing process, and the polishing accuracy is higher within the same time.

[0035] As shown Figure 1 in 5 Figures 6 and 7, a polishing device for mold production and processing includes a polishing processing execution end 10. A limiting ring 14 is provided at the bottom of the cylindrical connection block 12 and at the bottom of the linkage assembly 13. The polishing processing execution end 10 further includes a moving block 15 at one end of a fixed cross plate 11, and a driving motor 16 passing through the top of the fixed cross plate 11 and located in the inner cavity of the cylindrical connection block 12; an annular groove 121 is embedded at the bottom of the inner wall of the cylindrical connection block 12; the moving block 15 is connected to the driving member of the polishing processing execution end 10; the top of the limiting ring 14 is at the bottom of the annular internal gear 131;

[0036] The inner ring radius of the limiting ring 14 is smaller than the inner ring radius of the annular internal gear 131; the top of the limiting ring 14 is slidably connected to the bottom of the driven gear set 132.

[0037] It should be noted that in this embodiment, the moving block 15 at one end of the fixed cross plate 11 is used to be connected to the driving member of the polishing processing execution end 10, driving the polishing processing execution end 10 to move horizontally and vertically, so as to realize the overall polishing processing of the mold;

[0038] In addition, the depth of the annular groove 121 is greater than the radius of the addendum circle of the annular internal gear 131; during the rotation of the driven gear set 132, it plays a role in limiting the position. At the same time, the limiting ring 14 is arranged at the bottom of the linkage assembly 13, that is, it is slidably connected to the bottom of the driven gear set 132 to limit the bottom of the driven gear set 132, effectively ensuring the normal operation of this component.

[0039] The working principle of the present utility model is as follows:

[0040] In this device, the moving block 15 at one end of the fixed cross plate 11 is used to connect with the driving part of the polishing and processing execution end 10, driving the polishing and processing execution end 10 to move horizontally and vertically, so as to realize the overall polishing of the mold.

[0041] During the movement, the working end of the driving motor 16 arranged on the inner wall of the fixed cross plate 11 drives the driving gear 133 connected to its working end to rotate. Among them, the driving gear 133 is meshed with the driven gear set 132. When the driving gear 133 rotates, it drives the driven gear set 132 to rotate together.

[0042] It should be noted that the annular internal gear 131 is embedded in the annular groove 121 at the bottom of the cylindrical connecting block 12, and the annular internal gear 131 is meshed with the driven gear set 132. Therefore, the driven gear set 132 realizes continuous circular motion in the inner cavity of the cylindrical connecting block 12, and at the same time, the driven gear set 132 itself also rotates continuously.

[0043] The bottom of the driven gear set 132 is connected to the bottom of the gear in the polishing tool 134. To sum up, it realizes that the polishing tool 134 rotates around the driving gear 133 while rotating itself. Through double rotation, the polishing efficiency of the polishing tool 134 is faster than that of the traditional method during the polishing process, and the polishing accuracy is higher within the same time.

[0044] In addition, the depth of the annular groove 121 is greater than the radius of the addendum circle of the annular internal gear 131; during the rotation of the driven gear set 132, it plays a role in limiting the position. At the same time, the limiting ring 14 is arranged at the bottom of the linkage assembly 13, that is, it is slidably connected to the bottom of the driven gear set 132 to limit the bottom of the driven gear set 132, effectively ensuring the normal operation of this component.

[0045] The above embodiments are only used to illustrate the technical idea of the present utility model, and the protection scope of the present utility model cannot be limited by this. Any modification made on the basis of the technical solution according to the technical idea proposed by the present utility model falls within the protection scope of the present utility model.
