Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, the elliptical blade ring mold includes a mold sleeve 1. A stamping cavity 2 is provided inside the mold sleeve 1. A lower punch 3 is installed below the interior of the stamping cavity 2, and the lower punch 3 can be fixed inside the mold sleeve 1. An upper punch 4 is installed above the interior of the stamping cavity 2, and mold cavities 5 are symmetrically provided in the middle of both the lower punch 3 and the upper punch 4. A mold core 6 is installed inside the mold cavities 5 on both the lower punch 3 and the upper punch 4. An elliptical blade ring finished product 20 is stamped between the lower punch 3 and the upper punch 4. The lower punch 3 is placed inside the mold sleeve 1, and then the mold core 6 is slidably inserted into the lower punch 3. Inside the cavity 5 of the die 3, ceramic powder is injected into the gap between the die sleeve 1 and the die core 6. Then, the upper die 4 is slid on the outside of the die core 6. The upper die 4 is driven to descend by the hydraulic component, which will squeeze the ceramic powder between the die sleeve 1 and the die core 6 above the lower die 3. This is used to form the elliptical blade ring die casting. At this time, the elliptical blade ring has the blank outline of the elliptical blade ring. The lower die 3, the upper die 4, the die core 6 and the formed elliptical blade ring die casting will be taken out from inside the die sleeve 1. Then, the elliptical blade ring die casting is processed into the finished elliptical blade ring 20 by grinding and other operations, which greatly improves the processing efficiency.

[0022] like Figures 1 to 4 As shown, the mold sleeve 1 has symmetrical sliding holes 7 on both sides, and the insert rod 8 is slidably installed inside the sliding hole 7. The lower punch 3 has symmetrical insertion holes 9 in the middle, and the insert rod 8 is slidably connected to the insertion hole 9.

[0023] The lower punch 3 is placed inside the die sleeve 1, and the insert rod 8 is driven to slide inside the sliding hole 7, so that the insert rod 8 is inserted into the insertion hole 9 in the middle of the lower punch 3 to fix the position of the lower punch 3.

[0024] like Figures 1 to 4 As shown, the end of the insertion rod 8 is provided with a first chamfer 10.

[0025] This makes it easy to insert the plug 8 into the socket 9.

[0026] like Figures 1 to 4 As shown, fixing blocks 11 are symmetrically fixed on both sides of one end of the mold sleeve 1. A limiting hole 12 is opened in the middle of the fixing block 11. A limiting rod 13 is slidably installed inside the limiting hole 12. A connecting rod 14 is fixedly installed between one end of the two limiting rods 13. A guide frame 15 is fixedly installed at the end of the limiting rod 13 away from the connecting rod 14. A guide groove 16 is opened in the middle of the guide frame 15. The guide groove 16 is inclined. A guide rod 17 is fixedly installed on the outside of the insertion rod 8. The guide rod 17 and the guide groove 16 are pressed and slidably arranged.

[0027] Pushing the connecting rod 14 to move causes the limiting rod 13 to slide inside the limiting hole 12, which in turn causes the guide frame 15 to move. The guide groove 16 on the guide frame 15 presses against the guide rod 17 on the outside of the insertion rod 8, causing the insertion rod 8 to slide inside the sliding hole 7, which facilitates the movement of the insertion rod 8.

[0028] like Figures 1 to 4 As shown, the mold core 6 has a second chamfer 18 at both ends.

[0029] This facilitates the insertion of the mold core 6 into the cavity 5 of the lower punch 3 and the sliding of the upper punch 4 onto the outside of the mold core 6.

[0030] like Figures 1 to 4 As shown, the height of the mold core 6 is equal to the combined height of the lower punch 3 and the upper punch 4.

[0031] When the upper punch 4 is extruded by the hydraulic components, the ceramic powder will be in a compressed state to prevent the ceramic powder from being extruded and damaged by the upper punch 4.

[0032] like Figures 1 to 4 As shown, the top of the die sleeve 1 corresponding to the stamping cavity 2 has a third chamfer 19.

[0033] This facilitates the installation of the lower die 3 and the upper die 4 inside the stamping cavity 2.

[0034] This utility model provides an elliptical blade ring mold, the specific working principle of which is as follows:

[0035] When using the device, the lower punch 3 is placed inside the mold sleeve 1, and the connecting rod 14 is pushed to move, causing the limiting rod 13 to slide inside the limiting hole 12, which in turn moves the guide frame 15. The guide groove 16 on the guide frame 15 presses against the guide rod 17 on the outside of the insert rod 8, causing the insert rod 8 to slide inside the sliding hole 7, thus inserting the insert rod 8 into the insertion hole 9 in the middle of the lower punch 3 to fix the position of the lower punch 3. At this time, the bottom end of the lower punch 3 and the bottom end of the mold sleeve 1 are on the same plane. Then, the mold core 6 is slid into the mold cavity 5 of the lower punch 3. Then, ceramic powder is injected into the gap between the mold sleeve 1 and the mold core 6. Then, the upper punch 4 is slid outside the mold core 6, and the upper punch 4 is driven down by the hydraulic components, which causes the upper punch 4 to press. The ceramic powder between the mold sleeve 1 and the mold core 6 above the lower punch 3 is used to form the elliptical blade ring die casting. At this time, the elliptical blade ring already has the blank outline of the elliptical blade ring. Then, the connecting rod 14 is pushed in the opposite direction to move, which will drive the guide frame 15 to move in the opposite direction. Through the pressure of the guide groove 16 on the guide frame 15, the guide rod 17 outside the insertion rod 8 will be pushed to slide in the opposite direction inside the sliding hole 7, which will drive the insertion rod 8 to slide out of the insertion hole 9. Then, by keeping the position of the mold sleeve 1 fixed, the upper punch 4 and the mold core 6 are pressed, which will drive the lower punch 3, the upper punch 4, the mold core 6 and the formed elliptical blade ring die casting to be taken out from the mold sleeve 1. Then, the elliptical blade ring die casting is processed into the elliptical blade ring finished product 20 by grinding and other operations, which greatly improves the processing efficiency.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
