The feeding mechanism includes a conveying frame 9 and a running motor 29. The holder of the conveying frame 9 is fixedly connected to the outer wall of one side of the support plate 8, a plurality of rubber partition plates 10 are fixedly connected to the outer wall of the conveyor belt of the conveying frame 9, the conveying frame 9 is loaded with a plurality of processing inserts 11 separated by the rubber partition plates 10, the outer wall of one side of the running motor 29 is fixedly connected to the holder of the conveying frame 9, and the axial center of the running motor 29 is fixedly connected to the running shaft rod of the conveying frame 9.

[0023] In the present utility model, a plurality of processing inserts 11 are separated by a rubber partition plate 10, and the processing inserts 11 are sent one by one to the front of the limiting push plate 6. At this time, the vertical motor 3 is started to clamp the processing insert 11 through the limiting push plate 6 and push it above the communication hole 2. At this time, the processing insert 11 is fixed by the magnetic adsorption of the positioning magnetic plate 12.

[0024] Embodiment 2: On the basis of Embodiment 1, an adjusting convex block 18 is fixedly connected to the outer wall of the bottom of the connecting frame 13, a resisting block 19 is movably connected to the inner wall of the positioning bayonet 28, a limiting spring 23 is fixedly connected to the outer wall of one side of the resisting block 19, one end of the limiting spring 23 is fixedly connected to the inner wall of the support plate 8, an extension rod 26 is fixedly connected to the outer wall of one end of the shaft rod 4, an adjusting magnetic plate one 24 is fixedly connected to the outer wall of one end of the extension rod 26, and an adjusting magnetic plate two 25 is fixedly installed on the outer wall of one side of the resisting block 19. The adjusting magnetic plate one 24 is magnetically connected to the adjusting magnetic plate two 25.

[0025] In the present utility model, after the limiting push plate 6 places the processing insert 11, when the limiting push plate 6 withdraws, the adjusting magnetic plate one 24 connected to the shaft rod 4 will magnetically adsorb the adjusting magnetic plate two 25, thereby driving the resisting block 19 to move on the inner wall of the positioning bayonet 28. The adjusting convex block 18 loses the pressure of the resisting block 19 and drives the lower part of the processing insert 11. When the adjusting magnetic plate one 24 drags the resisting block 19 to move a certain distance, the compression intensity of the limiting spring 23 is higher than the magnetic attraction between the adjusting magnetic plate one 24 and the adjusting magnetic plate two 25. At this time, the adjusting magnetic plate two 25 disengages from the adjusting magnetic plate one 24, and the resisting block 19 uses the limiting spring 23 to rebound and return to place, moving the processing insert 11 upward and back into the injection mold sleeve 1.

[0026] Embodiment 3. On the basis of Embodiment 2, an installation groove 20 is formed in the outer wall of the top of the resisting block 19. A spring shock absorber 21 is fixedly installed on the inner wall of the bottom of the installation groove 20. The outer wall of the top of the spring shock absorber 21 is fixedly connected to a pulley assembly 22. The outer wall of the top of the pulley assembly 22 is movably connected to the outer wall of one side of the adjusting convex block 18. The adjusting convex block 18 is in the shape of an inverted triangular right angle.

[0027] The friction with the adjusting convex block 18 is reduced through the pulley assembly 22. When the processing insert 11 moves upward, the impact vibration is reduced through the spring shock absorber 21. With the magnetic adsorption of the positioning magnetic plate 12, the processing insert 11 can be kept stable better.

[0028] The working principle and usage process of the present utility model: In the present utility model, multiple processing inserts 11 are separated by the rubber partition plate 10, and the processing inserts 11 are sent one by one to the front of the limiting push plate 6. At this time, the vertical motor 3 is started to clamp the processing insert 11 through the limiting push plate 6 and push it to above the communication hole 2. At this time, the processing insert 11 is fixed through the magnetic adsorption of the positioning magnetic plate 12. Subsequently, the limiting push plate 6 withdraws and disengages from the processing insert 11. After the disengagement is completed, the connecting frame 13 moves downward, bringing the processing insert 11 into the communication hole 2. And with the downward movement of the connecting frame 13, the calibration plates 15 hinged on both sides of the connecting frame 13 will rotate around the hinge 14 and slide into the inner wall of the positioning bayonet 28 against the outer wall of the positioning bayonet 28. Through the angle change of the calibration plates 15, one ends of the two calibration plates 15 are simultaneously clamped against the processing insert 11, adjusting the processing insert 11 to complete the orientation calibration of the processing insert 11. Subsequently, the connecting frame 13 rises and the calibration plates 15 disengage from the positioning bayonet 28 groove. At this time, due to the magnetic repulsion between the magnet one 16 and the magnet two 17, the calibration plates 15 bounce off the outer wall of the processing insert 11, and the processing insert 11 moves upward and returns to the injection mold sleeve 1. In the present utility model, after the limiting push plate 6 places the processing insert 11, when the limiting push plate 6 withdraws, the adjusting magnetic plate one 24 connected to the shaft rod 4 magnetically adsorbs the adjusting magnetic plate two 25, thereby driving the resisting block 19 to move on the inner wall of the positioning bayonet 28. The adjusting convex block 18 loses the pressure of the resisting block 19 and drives the lower part of the processing insert 11. When the adjusting magnetic plate one 24 drags the resisting block 19 to move a certain distance, the compression intensity of the limiting spring 23 is higher than the magnetic attraction between the adjusting magnetic plate one 24 and the adjusting magnetic plate two 25. At this time, the adjusting magnetic plate two 25 disengages from the adjusting magnetic plate one 24, and the resisting block 19 rebounds and returns to its position by using the limiting spring 23, moving the processing insert 11 upward and back into the injection mold sleeve 1. The friction with the adjusting convex block 18 is reduced through the pulley assembly 22. When the processing insert 11 moves upward, the impact vibration is reduced through the spring shock absorber 21. With the magnetic adsorption of the positioning magnetic plate 12, the processing insert 11 can be kept stable better.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
