[0002] A precision milling device for molds, as described in Chinese patent document CN207709968U, features a positioning groove on a milling table and a sliding block on the underside of a bolster bar that slides within the positioning groove, allowing the bolster bar to move on the milling table and thus facilitating the fixing of molds of different lengths to be milled. Furthermore, a cross groove is provided on the bolster bar, and a cross slider adapted to it is provided at the lower end of a positioning screw, allowing the positioning screw to move on the bolster bar and facilitating the fixing of molds of different widths to be milled, effectively broadening the applicability of this invention. Simultaneously, due to the multi-segment tight fit between the cross slider and the cross groove, the mold to be milled can be firmly fixed by tightening the pressure plate with a nut, effectively improving the stability of the positioning screw and ensuring stable mold positioning, thereby effectively guaranteeing milling accuracy and improving the surface finish of the mold.

[0003] The aforementioned mold milling device can only process one side of the mold. When it is necessary to process all four sides of the mold, the mold needs to be frequently disassembled and flipped, which increases the processing time. Utility Model Content

There are two sets of sealing plates, and a bidirectional lead screw 7 is rotatably installed on the adjacent side walls of the two sets of sealing plates. A first drive motor 20 is fixedly installed on one side of one set of sealing plates. The shaft of the first drive motor 20 is fixedly installed with one end of the bidirectional lead screw 7. A movable seat 8 is threaded onto the outer wall of the bidirectional lead screw 7. The movable seat 8 is slidably installed with the transmission groove on the transmission base 1.

[0023] Working principle: In use, the mold steel is placed between two sets of clamping plates 16. Then, the first drive motor 20 is started, which drives the bidirectional lead screw 7 to rotate. The rotation of the bidirectional lead screw 7 drives the moving seat 8 and the connecting column 9 to move. The movement of the connecting column 9 drives the strip support seat 10 and the fixed vertical rod 11 to move. The movement of the fixed vertical rod 11 drives the fixed plate 12 to move. When the fixed plate 12 moves, the clamping plate 16 can be moved, thereby clamping the mold steel. Then, the mold steel is processed by the precision milling mechanism 6. After one side of the mold steel is processed, the second drive motor 21 is started. 1. The start-up mechanism drives the rotating rod 13 and the rotating disk 14 to rotate. The rotation of the rotating disk 14 drives the rotating sleeve 15 to rotate. The rotation of the rotating sleeve 15, through the limiting post 19, drives the mounting post 18 and the clamping plate 16 to rotate. The rotation of the clamping plate 16, through the limiting post 17, allows the mold steel to rotate. When the clamping plate 16 needs to be replaced according to different mold steels, the clamping plate 16 is moved to pull the mounting post 18 out of the rotating sleeve 15. Then, the mounting post 18 on the replacement clamping plate 16 is inserted into the rotating sleeve 15, and the limiting post 19 is positioned in the opening on the rotating sleeve 15 to complete the replacement.
