Shoe molds, blade molds, bottle molds and other molds, as well as general metal parts, generally have the same requirements for technical indicators such as size, tolerance, and surface roughness during the production process. In the process of mass production, if traditional processing methods are used, they need to be processed and produced one by one on a machine tool. The parts processed and produced per unit time are limited by the number of machine tools and the number of operators. In addition, the proficiency of operators varies greatly, and productivity is inevitably greatly limited within the relatively limited time required by the production cycle. In addition, in the processing and production process of some parts or molds, they are required to be paired in pairs, and it is difficult to guarantee the requirements with traditional processing methods.

[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0017] Embodiment 1, as Figure 1~2As shown, a double-station shoe mold engraving and milling machine with a tool magazine includes a frame 1, on which two movable workbenches are arranged, above which a crossbeam 3 mounted on the frame 1 is arranged, on which a spindle device corresponding to the two movable workbenches is arranged one by one, on which a column 4 is arranged on both sides of the crossbeam 3, a fixed bracket 5 is arranged on the side of the column 4, and a rotating tool magazine device is installed on the fixed bracket 5.

[0018] In this embodiment, the spindle device includes a transverse moving mechanism 6 arranged on the crossbeam 3, and a lifting mechanism 7 is arranged on the transverse moving mechanism 6, and a spindle box 8 is arranged on the lifting mechanism 7. The transverse moving mechanism 6 controls the lifting mechanism 7 to move transversely on the crossbeam 3, and the lifting mechanism 7 is used to control the lifting and lowering movement of the spindle box 8. The transverse moving mechanism 6 and the lifting mechanism 7 are both drive motors, screw nut mechanisms, and slide rail components, etc., which are all existing technologies and will not be described in detail here.

[0019] The frame 1 is provided with inclined slopes on both sides of the movable workbench, and a material clearing port 20 is opened on one side of the frame 1. The material clearing port 20 is located at the lower part of the inclined slope.

[0020] In this embodiment, the movable workbench includes a longitudinal moving mechanism arranged on a frame 1 , a working base 9 is arranged on the longitudinal moving mechanism, and a rotating base 10 is installed on the working base 9 .

[0021] In this embodiment, the longitudinal movement mechanism includes a longitudinal movement box 11 and a longitudinal movement assembly installed in the longitudinal movement box 11. The top of the longitudinal movement box 11 is provided with a conical cover 12, and the bottom of the working base 9 is provided with a slide plate 13 slidably arranged on the conical cover 12. The two side walls of the longitudinal movement box 11 are respectively provided with openings, and the two sides of the working base 9 are respectively connected to the longitudinal movement assembly through the corresponding openings.
