[0027] Figure 1-Figure 3 The structure diagram of one embodiment of a mold fine grinding device of the present invention is shown. Figure 1-Figure 3 The present embodiment is a mold fine grinding device, the main body of which includes a top plate 100, a lifting and rotating assembly 200 and a grinding assembly 300.

[0028] Top plate 100. Preferably, in this embodiment, a mounting plate 101 is vertically fixed to the side wall of the top plate 100, and mounting bolts 102 are provided on the mounting plate 101. The mounting bolts 102 penetrate the mounting plate 101, and the top plate 100 is installed at a designated position by the mounting bolts 102 under the action of the mounting plate 101, thereby ensuring the stable placement of the top plate 100.

[0029] The lifting and rotating assembly 200 includes a hydraulic push rod 210 vertically fixed to the middle of the lower end of the top plate 100, a driving motor 220 arranged at the lower end of the hydraulic push rod 210, and a cross plate 230 fixed to the output end of the driving motor 220. Preferably, in the present embodiment, a first connecting portion 221 is fixed to the middle of the upper end of the driving motor 220, and a first bolt 222 is arranged on the outer wall of the first connecting portion 221. The first bolt 222 penetrates the first connecting portion 221 to the hydraulic push rod 210. The driving motor 220 is installed at the lower end of the hydraulic push rod 210 through the first bolt 222 under the action of the first connecting portion 221. The operator can remove the driving motor 220 from the lower end of the hydraulic push rod 210 by removing the first bolt 222 at a later stage, so as to disassemble and overhaul it. A fixing plate 223 is fixed to the outer wall of the driving motor 220. The fixing plate 223 is arranged on the outer wall of the middle of the lower end of the fixing plate 223. A limiting groove 224 is provided on the side, and a limiting rod 231 is vertically fixed on the upper end of the cross plate 230. The outer wall of the limiting rod 231 fits with the inner wall of the limiting groove 224. When the driving motor 220 drives the cross plate 230 to rotate, the limiting rod 231 at the upper end of the cross plate 230 moves synchronously therewith. During the movement, the limiting rod 231 generates a certain friction force with the limiting groove 224 at the lower end of the fixed plate 223, thereby ensuring the stability of the cross plate 230 during the rotation process. Four limiting rods 231 are provided, and the four limiting rods 231 are symmetrically arranged in pairs. The four limiting rods 231 further ensure the stability of the cross plate 230 during the rotation process.

[0030] The grinding assembly 300 includes a plurality of grinding motors 310 arranged outside the middle of the lower end of the cross plate 230 and a grinding head 320 arranged at the output end of the grinding motor 310. Preferably, in this embodiment, a second connecting portion 321 is fixed to the middle of the upper end of the grinding head 320, and a second bolt 322 is arranged on the outer wall of the second connecting portion 321. The second bolt 322 penetrates the second connecting portion 321 to the output end of the grinding motor 310. The grinding head 320 is installed on the output end of the grinding motor 310 by the second bolt 322 under the action of the second connecting portion 321. The operator can remove the grinding head 320 from the lower end of the grinding motor 310 by removing the second bolt 322, so as to facilitate the disassembly and replacement of the grinding head 320.

[0031] Combination Figure 1-Figure 3, a mold fine grinding device of the present embodiment is specifically used as follows: the operator installs the top plate 100 at the specified position by installing the bolts 102. When the mold needs to be finely ground, the operator selects a suitable grinding assembly 300 and a grinding head 320 according to actual usage conditions, and starts the drive motor 220. The drive motor 220 drives the cross plate 230 to rotate. The cross plate 230 drives the lower end of the grinding assembly 300 to move during the rotation, so that the position of the grinding assembly 300 can be adjusted. After adjusting the suitable grinding assembly 300 and the grinding head 320 to the specified position, the grinding motor 310 is started. The grinding motor 310 controls the rotation of the grinding head 320, and then the grinding assembly 300 is pushed downward by the hydraulic push rod 210, so as to finely grind the mold. The entire device does not need to replace the grinding device or the grinding head 320 during the grinding process, which saves time and improves the grinding efficiency of the device.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
