Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3, An injection molding part shaping jig in this embodiment includes a base 1. A motor 2 is fixedly connected to the right side surface of the base 1. An output shaft 3 is rotatably connected inside the motor 2. The outer circumferential surface of the output shaft 3 is rotatably connected to the inside of the base 1. Two threaded tubes 4 are threadedly connected to the outer circumferential surface of the output shaft 3. A connecting plate 5 is fixedly connected to the outer circumferential surface of each threaded tube 4. A positioning plate 6 is fixedly connected to the upper surface of the connecting plate 5. Two columns 9 are fixedly connected to the upper surface of the base 1. A cross plate 10 is slidably connected to the outer circumferential surfaces of the two columns 9. A sliding plate 11 is slidably connected to the cross plate 10 through a groove opened on the upper surface. A blade 12 is provided on the upper surface of the sliding plate 11.

[0031] Please refer to Figure 1 and Figure 3 , Anti-slip sheets 7 are fixedly connected to the closer sides of the two positioning plates 6. Anti-slip grooves arranged at equal intervals are opened inside the anti-slip sheets 7, which can prevent the parts to be shaped from sliding and shifting easily after being positioned, increase the stability during part shaping, and ensure the shaping quality.

[0032] Please refer to Figure 1 and Figure 3 , A limiting groove 8 is opened inside the base 1. The outer surface of the connecting plate 5 is slidably connected to the base 1 through the limiting groove 8, which restricts the threaded tube 4 and prevents the threaded tube 4 from rotating with the output shaft 3, so that the threaded tube 4 always moves horizontally.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4 , An electric push rod 13 is fixedly connected to the bottom surface of the cross plate 10. A fixing plate 14 is fixedly connected to the front end of the electric push rod 13. The upper surface of the fixing plate 14 is fixedly connected to the bottom surface of the sliding plate 11. The electric push rod 13 drives the sliding plate 11 to move, and then drives the blade 12 to move to complete the shaping operation of the part.

[0034] Please refer to Figure 1 and Figure 4 , Two bolts 15 are threadedly connected inside the blade 12. The outer circumferential surface of each bolt 15 is threadedly connected to the inside of the sliding plate 11. The blade 12 and the sliding plate 11 are fixedly connected through the bolts 15, which is convenient for the installation and disassembly of the blade 12.

[0035] Please refer to Figure 1 , Figure 2 and Figure 4 , A control rod 16 is rotatably inserted into the inside of the base 1. The outer circumferential surface of the control rod 16 is threadedly connected to the inside of the cross plate 10. When the control rod 16 rotates, it drives the cross plate 10 to rise and fall, and then adjusts the trimming height of the part as needed, improving the flexibility and practicality of the jig.

[0036] Please refer toFigure 4 On the outer circumferential surface of the control rod 16, a limit ring 17 is fixedly sleeved. The outer circumferential surface of the limit ring 17 is rotatably connected to the inside of the base 1 to restrict the control rod 16 and prevent the control rod 16 from sliding and shifting, thereby increasing the stability of the movement of the control rod 16.

[0037] Please refer to Figure 3 On the outer circumferential surface of the output shaft 3, there are two threaded structures. The threaded track directions of the two threaded structures on the outer circumferential surface of the output shaft 3 are opposite, which causes the threaded tube 4 to move in opposite directions, and then the positioning plate 6 moves in and out, completing the positioning of the part.

[0038] An injection molded part shaping fixture in this embodiment drives the threaded tube 4 to move in opposite directions during the rotation of the output shaft 3, causing the positioning plate 6 to move in and out. By setting the electric push rod 13 and the blade 12, the part can automatically complete the shaping operation after being positioned. When the control rod 16 rotates, it drives the cross plate 10 to rise and fall, enabling the trimming height of the part to be adjusted. It achieves the effect of automatically positioning and shaping the part, saving labor, and improving the flexibility and practicality of the fixture, and solves the problem that it is laborious to manually shape injection molded parts and the shaping quality cannot be guaranteed.

[0039] It should be noted that a handwheel is provided at the top of the control rod 16, and the control rod 16 can be manipulated through the handwheel.

[0040] The working principle of the above embodiment is as follows:

[0041] When an injection molded part needs to be shaped, the part is placed closely against the cross plate 10 on the base 1. Then, the motor 2 is started as the power to drive the output shaft 3 to rotate. The output shaft 3 drives the connecting plate 5 to move inward through the threaded tube 4. The connecting plate 5 drives the positioning plate 6 and the anti-slip sheet 7 to move inward. Immediately, the positioning plate 6 and the anti-slip sheet 7 clamp the part to position the part. Then, the electric push rod 13 is started to drive the sliding plate 11 to move through the fixing plate 14. The sliding plate 11 drives the blade 12 to move through the bolt 15. The blade 12 then cuts off the part that is higher than the cross plate 10 during the movement, completing the shaping operation of the part. The control rod 16 can be rotated to drive the cross plate 10 to rise and fall, and the trimming height of different injection molded parts to be shaped can be adjusted as needed.
