The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1 and 2, the present invention provides a mold processing and polishing apparatus, which includes a mounting frame 1, a driving structure 2 disposed on the mounting frame 1, a rotating mounting plate 3 connected to an output end of the driving structure 2, and a polishing assembly 4 detachably disposed on the rotating mounting plate 3; wherein the content of the first and second substances,

the rotary mounting plate 3 comprises an annular mounting part 31 which is arranged in a surrounding way along the circumferential direction, and an inserting part 32 which is coaxially arranged with the annular mounting part 31;

the grinding assembly 4 comprises a peripheral grinding structure 41 detachably connected to the annular mounting portion 31, and a hole grinding structure 42 connected to the insertion portion 32.

According to the invention, the annular mounting part 31 and the inserting part 32 are matched, the periphery polishing structure 41 and the hole body polishing structure 42 are respectively detachably mounted, the periphery of the hole body to be polished is polished by the periphery polishing structure 41, and meanwhile, the inner wall of the hole body is polished in a targeted manner by the hole body polishing structure 42, so that the synchronous polishing operation of the hole body and the peripheral part is completed. Further, can be through the two setting of dismantling, the corresponding subassembly 4 of polishing of changing accomplishes the classification operation of different hole bodies, improves holistic operating efficiency greatly.

In a preferred embodiment of the invention, in order to avoid a stop of the peripheral grinding structure 41 provided on the annular mounting portion 31 against the bore grinding structure 42 provided on the insertion portion 32, an end face of the insertion portion 32 remote from the drive structure 2 projects beyond an end face of the annular mounting portion 31.

Meanwhile, the driving structure 2 can drive the annular mounting portion 31 and the inserting portion 32 to move synchronously, so as to drive the periphery polishing structure 41 and the hole polishing structure 42 to polish synchronously, however, in the actual operation process, the rotation rates of the periphery polishing structure 41 and the hole polishing structure 42 need to be further adjusted according to the difference of requirements such as precision and the like, so that in a more preferable embodiment, the output end of the driving structure 2 is coaxially connected with the inserting portion 32;
