Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a temperature-controlled automotive fixture 3D printing uniform discharge nozzle includes a mounting part 1, a connecting rod 2 fixedly mounted on the top of the mounting part 1, a threaded post 3 fixedly mounted on the top of the connecting rod 2, and a fixing plate 8 fixedly mounted on one side of the mounting part 1.

[0028] The bottom of the mounting component 1 is provided with an adjustment mechanism 7, and the top of the fixing plate 8 is provided with a rotation mechanism 9.

[0029] In this embodiment, the ejector nozzle is installed to the 3D printer via the threaded post 3, and the connecting pipe 5 is connected to the material cylinder via the conduit. When the nozzle size needs to be changed, the nozzle size can be quickly adjusted by the cooperation of the rotating mechanism 9 and the adjusting mechanism 7 without disassembling or replacing the ejector nozzle, which greatly improves the efficiency of 3D printing automotive fixtures.

[0030] In one embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the adjusting mechanism 7 includes a first gear 701, which is fitted to the bottom of the mounting part 1. A sealing ring 702 is fixedly mounted annularly at equal intervals on the top of the first gear 701, and a nozzle body 703 corresponding to the sealing ring 702 is fixedly mounted annularly at equal intervals on the bottom of the first gear 701. A bolt 704 passes through the center point of the bottom of the first gear 701, and the bolt 704 is threadedly connected to the mounting part 1. A knob 901 is rotatably mounted on the top of the fixing plate 8. The bottom end of the knob 901 passes through the fixing plate 8 and is connected to a second gear 902. The second gear 902 meshes with the first gear 701. The bottom is provided with equidistant annular sealing grooves 13, which are adapted to the sealing ring 702. When the nozzle size needs to be adjusted, the bolt 704 is loosened with a tool, causing the first gear 701 to move downward and the sealing ring 702 to separate from the sealing groove 13. At this time, the knob 901 is turned to drive the second gear 902 to rotate. The rotation of the second gear 902 drives the nozzle body 703 to rotate. After the nozzle body 703 of the corresponding size is aligned with the discharge groove 12, the bolt 704 is tightened, and the first gear 701 moves upward, so that the sealing ring 702 enters the interior of the sealing groove 13. This structure is simple, can quickly adjust the nozzle size, and improves practicality.

[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the top of the mounting component 1 is provided with a feeding assembly in a ring at equal intervals. The feeding assembly includes a solenoid valve assembly 4, which is fixedly installed in a ring at equal intervals on the top of the mounting component 1. A connecting pipe 5 is fixedly installed on the top of the solenoid valve assembly 4, and the connecting pipe 5 is connected to the material cylinder through a conduit. The solenoid valve assembly 4 can control whether the material can enter the interior of the guide trough 6. The solenoid valve assembly 4 is an existing mature device and does not need to be described in detail. The material cylinder continuously supplies material to the connecting pipe 5.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, the mounting component 1 has a guide groove 6 inside and a discharge groove 12 at the bottom center point. Multiple connecting pipes 5 are connected to material cylinders containing different materials inside. The material is supplied through the material cylinders. When a certain material is needed, the corresponding solenoid valve assembly 4 is opened and the other solenoid valve assemblies 4 are closed. The material enters the interior of the guide groove 6 and is finally discharged through the discharge groove 12.

[0033] In one embodiment, such as Figure 2As shown, the connecting rod 2 is equipped with an extrusion assembly, which includes a motor 10. The motor 10 is fixedly installed inside the connecting rod 2. The output end of the connecting rod 2 is connected to a conveying rod 11, which is located inside the guide trough 6. The vertical center line of the conveying rod 11 coincides with the vertical center line of the discharge trough 12. After the material enters the guide trough 6, the motor 10 drives the conveying rod 11 to rotate. The rotation of the conveying rod 11 effectively conveys the material inside the guide trough 6 to the discharge trough 12. Finally, the material is extruded through the nozzle body 703.

[0034] Working principle: The ejector nozzle is installed on the 3D printer via the threaded post 3. Fixtures are required during the processing of automotive parts. The 3D printer can print automotive fixtures of complex dimensions, improving manufacturing efficiency. During the printing process, different sized nozzles are used depending on the requirements. When the nozzle size needs to be adjusted, the bolt 704 is loosened with a tool, causing the first gear 701 to move downwards, separating the sealing ring 702 from the sealing groove 13. At this time, rotating the knob 901 drives the second gear 902 to rotate, which in turn drives the nozzle body 703 to rotate. After the nozzle body 703 of the corresponding size aligns with the ejector groove 12, Tighten bolt 704, and the first gear 701 moves upward, causing the sealing ring 702 to enter the interior of the sealing groove 13. This structure is simple and allows for quick adjustment of the nozzle size, improving practicality. Multiple connecting pipes 5 are connected to material cylinders containing different materials. Materials are supplied through the material cylinders. When a material is needed, the corresponding solenoid valve assembly 4 opens, while the other solenoid valve assemblies 4 close. The material enters the interior of the guide trough 6. The motor 10 drives the conveying rod 11 to rotate. The rotation of the conveying rod 11 effectively conveys the material inside the guide trough 6 to the discharge trough 12. Finally, the material is extruded through the nozzle body 703, effectively completing the manufacturing of the automotive fixture.

[0035] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
