[0031] The embodiment of the present application discloses a motor housing forming die, such as Figure 1 As shown, it includes a working frame 1, an upper mold 2, and a lower mold 3. The lower mold 2 is fixedly connected to the working frame 1, the upper mold 2 is located above the lower mold 3 and moves relative to the working frame 1, a guide component 7 is provided between the upper mold 2 and the lower mold 3 to guide the moving path of the upper mold 2, and a driving component 8 is provided on the working frame 1 to drive the upper mold 2 to move and open and close with the lower mold 3, an upper mold core 4 is installed in the upper mold 2, and a lower mold core 5 is installed in the lower mold 3, a seal is provided between the upper mold core 4 and the lower mold core 5, and the seal is a rubber pad 6, which is fixedly connected to the upper mold core 4 and abuts against the lower mold core 5. When the mold is closed, the lower mold core 5 is pressed against the rubber pad 6, and the rubber pad 6 is elastic. The lower mold core 5 can push the rubber pad 6 to extrude inward at the abutment point, abut the boundary and wrap outward, thereby improving the airtightness effect between the upper mold core 4 and the lower mold core 5.

[0032] like Figure 2 and Figure 3 As shown, the drive assembly 8 includes a rotating column 9, a rotating plate 10, a connecting plate 11, a screw 12 and a motor 13. A groove 30 is provided on the work frame 1 in the vertical direction. The rotating column 9 is cylindrical and its axis is arranged in the vertical direction. The two ends of the rotating column 9 are respectively rotatably connected to the upper and lower opposite inner walls of the groove 30 on the work frame 1. The rotating plate 10 is fixedly sleeved on the rotating column 9. A slide groove 14 is provided on the side of the rotating plate 10 away from the rotating column 9 in the vertical direction. The axis of the screw 12 is arranged in the vertical direction and the two ends of the screw 12 are respectively rotatably connected to the upper and lower ends of the slide groove 14. The motor 13 is fixedly installed on the top of the rotating plate 10 and the rotating shaft of the motor 13 is fixedly welded to the screw 12. The connecting plate 11 is threadedly connected to the screw 12. The connecting plate 11 is rectangular and fixedly connected to the side wall of the upper mold 2.

[0033] like Figure 3 and Figure 4 As shown, the guide assembly 7 includes a fixed block 15, a fixed block 16 and a guide rod 17. The fixed block 15 is fixedly welded to the side wall of the upper mold 2, and the fixed block 16 is fixedly welded to the side wall of the lower mold 3. The fixed block 15 and the fixed block 16 are correspondingly arranged. The guide rod 17 is fixedly welded to the lower end surface of the fixed block 15. The fixed block 16 is provided with a guide groove 31 in the vertical direction for the guide rod 17 to be inserted. The guide rod 17 is retractable and includes a main rod and a telescopic rod 19. The top of the main rod is fixedly welded to the lower end surface of the fixed block 15, and the bottom end of the main rod is provided with a telescopic groove 20 in the vertical direction. The telescopic rod 19 slides in the telescopic groove 20 in the vertical direction. A limiting block 22 is fixedly welded to the top of the telescopic rod 19, and a limiting groove 21 is provided on the inner wall of the telescopic groove 20. The limiting block 22 is slidably connected to the inner wall of the limiting groove 21. The telescopic rod 19 is inserted into the guide groove 31, and two groups of limiting components 23 for limiting the position of the telescopic rod 19 are provided in the limiting groove 21.

[0034] like Figure 4 As shown, the limiting assembly 23 includes a limiting block 24, a spring 27, and a limiting rod 25. The limiting block 24 is horizontally penetrated through the inner wall of the main rod and is provided with a slope 26 at one end close to the limiting block 22. The limiting block 22 abuts against the slope 26. The limiting rod 25 is horizontally set and penetrates the outer wall of the main rod and is fixedly welded to the end of the limiting block 24 away from the slope 26. The end of the limiting rod 25 away from the limiting block 24 is fixedly welded with a pulling block 28. The spring 27 is horizontally set and sleeved on the limiting rod 25. The two ends of the spring 27 are respectively fixedly welded to the pulling block 28 and the outer wall of the main rod; the working frame 1 is located near the lower mold 3 and is hinged with a detection rod 29. When the detection rod 29 is rotated to a vertical state, the detection rod 29 abuts against the fixed block 2 16 and the fixed block 1 15.

[0035] like Figure 1 andFigure 3 As shown, when the staff performs the reverse mold, the staff first rotates the rotating plate 10 to drive the upper mold 2 to rotate, so that the upper mold 2 is rotated above the lower mold 3. At this time, the staff can determine according to the guide rod 17. When the staff rotates the upper mold 2 close to the lower mold 3, the staff pulls the limiting rod 25 to drive the limiting block 24 to move away from the limiting block 22, thereby releasing the limiting of the telescopic rod 19. At this time, the telescopic rod 19 moves downward under its own gravity, and the bottom end abuts the upper end surface of the fixed block two 16. Then, the staff slowly rotates the upper mold 2 to drive the telescopic rod 19 to slowly move on the surface of the fixed block two 16 until the telescopic rod 19 is just inserted into the guide groove 31, thereby reducing the possibility of deviation when the upper mold 2 and the lower mold 3 are closed. Then, the staff drives the screw rod 12 to rotate through the motor 13, and the screw rod 12 rotates to drive the connecting plate 11 to move, thereby driving the upper mold 2 and the lower mold 3 to abut and close. Since the screw rod 12 has a self-locking function, the screw rod 12 can drive the upper mold 2 to abut against the lower mold 3 and remain stable, and is not easy to move.

[0036] As shown in Figure 1 When the upper mold 2 and the lower mold 3 are closed, the staff rotates the detection rod 29 to the vertical state, and the detection rod 29 is perpendicular to the fixed block two 16 and just does not rub against the fixed block two 16. Then, the position between the upper end side wall of the detection rod 29 and the fixed block one 15 is observed, so as to determine whether the fixed block one 15 and the fixed block two 16 are aligned, thereby reducing the possibility of unknown inclination bending or inclination of the guide rod 17.

[0037] As shown in Figure 1 and Figure 4 When the staff needs to open the upper mold 2 to take out the model after the pouring mold is solidified, the staff first pushes the telescopic rod 19 to move into the telescopic slot 20, and the limiting block 22 moves upward and abuts against the inclined surface 26 on the limiting block 24. The limiting block 22 pushes the limiting block 24 through the inclined surface 26 to drive the limiting rod 25 to move outwardly to stretch the spring 27. When the limiting block 22 passes the limiting block 24, the limiting rod 25 pushes the limiting block 22 to move under the pulling of the spring 27. The upper end surface of the limiting block 24 abuts against the lower end surface of the limiting block 22, thereby limiting the telescopic property of the telescopic rod 19, shortening the length of the guide rod 17, and avoiding the staff from affecting the rotation of the upper mold 2 when opening the mold.

[0038] As shown in Figure 1As shown, the worker drives the screw rod 12 to rotate through the motor 13, the screw rod 12 drives the connecting plate 11 to move the upper mold 2 away from the lower mold 3, so as to open the mold, then the worker drives the rotating plate 10 to rotate, so as to drive the upper mold 2 to rotate, and the position of the upper mold 2 is offset relative to the lower mold 3, so as to facilitate the worker to take out the model, reduce the influence of the upper mold 2 on the worker's vision, or avoid the possibility that the worker is easily bumped into the upper mold 2 and is injured.

[0039] The implementation principle of the embodiment of the application is that the worker drives the upper mold 2 to move through the driving assembly 8, and under the action of the guiding assembly 7, the upper mold 2 and the lower mold 3 abut and close, and under the action of the sealing element, the sealing property between the upper mold 2 and the lower mold 3 is enhanced, the possibility of leakage of the pouring liquid is reduced, so as to improve the mold closing precision and the molding efficiency.

[0040] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
