i, the fixed and pouring stage of fan export direction quiet leaf subassembly: under the action of the positioning spring 10 and the positioning long bolt 9, the upper positioning plate 7 is at a proper height, and the fan outlet guide stationary blade assembly 11 is fixedly installed with the upper positioning plate 7 directly through three bolts. And placing the upper cavity middle pressure plate 15 at the inner end of the fan outlet guide stationary blade assembly 11, and screwing the positioning long bolt 9 to enable the fan outlet guide stationary blade assembly 11 and the upper cavity middle pressure plate 15 to descend together. When the upper cavity middle pressing plate 15 contacts the lower cavity base 12, the upper cavity middle pressing plate 15 is fixed on the lower cavity base 12 by using bolts, and at the moment, the upper positioning plate 7 is in seamless fit with the left and right vertical plates 5 and 6. And (3) installing an upper cavity left pressing plate 15, an upper cavity right pressing plate 14, a clamping plate 16 and a clamping block 17 on the module, and completing the installation of the multi-process blade fixing and pouring module 1. Fixing the multi-process blade and adjusting the direction of the pouring module 1 to enable a pouring port to be placed upwards; introducing the model pouring liquid into the cavity through the pouring gate, and discharging air in the cavity from the other pouring gate; when the model pouring liquid flows out of the exhaust pouring port, the model pouring liquid is filled in the cavity, and the injection of the model pouring liquid is stopped; finally, the model meets the requirements through vulcanization treatment.

II, module-integral installation stage: the vulcanized multi-process blade fixing and pouring module 1 is adjusted to be placed in the direction that the platform at the outer end of the fan outlet guide stationary blade assembly 11 is upward, and the lifting connecting slide rail 27 is installed on the upper positioning plate 7. The multi-process blade fixing and casting module 1 is placed on the bottom plate 19, and the left and right side faces of the module bottom plate 4 are respectively contacted with the left positioning plate 21 and the right positioning plate 22. Promote the fixed and pouring module 1 of multiple operation blade, make lift link block 26 pass lift link slide 27 at the promotion in-process, when limiting plate 20 is touched to module bottom plate 4, stop promoting, fix and pour module 1 preliminary location to the multiple operation blade this moment. And (3) penetrating the limiting slide block 23 through slide block positioning holes of the left positioning plate 21 and the right positioning plate 22, respectively connecting the limiting slide block to the left vertical plate 5 and the right vertical plate 6 through bolts, and positioning the multi-process blade fixing and pouring module 1 to complete module-integral installation.

III, demolding of the middle pressing plate of the upper cavity: and starting the lifting cylinder 25, under the guide of the slide block guide holes of the left positioning plate 21 and the right positioning plate 22, the lifting connecting slide block 26 moves in the slide groove of the lifting connecting slide rail 27, and simultaneously, the multi-process blade fixing and pouring module 1 is obliquely lifted upwards. When the upper cavity middle pressure plate 15 and the upper cavity middle pressure plate connecting block 39 are at the same height, the lifting cylinder 25 is closed. The upper cavity middle pressure plate 15 is fixedly connected with the upper cavity middle pressure plate connecting block 39 through bolts, and then the bolts connecting the upper cavity middle pressure plate 15 with the lower cavity base 12 are unscrewed. And starting the lifting cylinder 25, leading the multi-process blade fixing and pouring module 1 to obliquely descend under the guide of the slide block guide holes of the left positioning plate 21 and the right positioning plate 22, and closing the lifting cylinder when the module bottom plate 4 is contacted with the bottom plate 19. The horizontal cylinder 31 is started, and the horizontal connecting slide block 37 is pulled towards the horizontal cylinder 31 under the action of the slide rail formed by the left and right horizontal slide rails 33 and 34. Because the key slot hole of the horizontal connecting sliding block 37 does not limit the transverse movement of the transmission strut 35, the transmission strut 35 and the transmission combination block 36 move along the sliding groove in the bearing platform 28 and the fixed upper cover 40 through the movement of the horizontal connecting sliding block 37, the front half section of the sliding groove is an arc section, and the rear half section of the sliding groove is a straight section. In the first half of the movement of the transmission strut 35, the transmission strut 35 drives the rotation limiting slide block 38 to rotate in the circular chute of the fixed upper cover 40, so that the pressure plate 15 in the upper cavity does rotation, in the second half of the movement of the transmission strut 35, the rotation limiting slide block 38 finishes rotating, and simultaneously starts to linearly move in the linear chute of the fixed upper cover 40, so as to drive the pressure plate 15 in the upper cavity to linearly move, after the pressure plate 15 in the upper cavity is separated from the multi-process blade fixing and pouring module 1, the horizontal cylinder is closed, and under the linear movement path after the pressure plate 15 in the upper cavity rotates firstly, the pressure plate 15 in the upper cavity is successfully dismounted from the module without damaging the surface of the fan outlet guide stationary blade assembly 11.
