[0002] Internal combustion engines are the core power units of modern transportation and industrial equipment. The performance and manufacturing process of their components have a crucial impact on the overall performance. The manufacturing of traditional internal combustion engine components mainly relies on metal materials, such as steel, cast iron and non-ferrous metal alloys. However, with the continuous improvement of the performance requirements of internal combustion engines, these traditional materials have gradually exposed their limitations in thermal, mechanical, chemical and physical properties. Therefore, engineering plastics and ceramic materials have gradually become new choices for the manufacture of internal combustion engine components due to their unique performance advantages, such as lightweight, corrosion resistance, and high temperature resistance.

[0003] In the prior art, the manufacturing of internal combustion engine parts mainly relies on traditional machining and injection molding processes. Although these processes are mature, they have many shortcomings when producing plastic and ceramic parts with complex shapes. For example, traditional machining requires multiple processes, the machining accuracy is difficult to guarantee, and the production efficiency is low; injection molding requires complex mold design and manufacturing, which is costly and difficult to achieve multi-material integrated manufacturing.

The driving mechanism controls the movement of the synchronous belt 17 through the driving wheel 18, thereby realizing precise control of the nozzle device 80.

[0041] like Figure 6 , Figure 7 As shown, the nozzle device 80 includes a heat-conducting pipe 806, a spiral extrusion shaft 810, a connecting pipe 807 and a nozzle 808. The heat-conducting pipe 806 is installed on the movable platform 14, and the spiral extrusion shaft 810 is rotatably installed in the heat-conducting pipe 806.

[0043] Three feed ports 309 are evenly arranged around the heat pipe 806, which are connected to the dual material cylinder 310 and the colloid cylinder 702 through the hose 15, respectively, to form a closed material conveying loop, and realize continuous automatic feeding during the working process. During operation, the material enters the heat pipe 806 from the nozzle inlet 805, and the heating rod in the heating rod bayonet 811 is heated to ensure the temperature inside the heat pipe 806, so that the material entering the heat pipe 806 can remain in a molten state. The nozzle motor 801 drives the spiral extrusion shaft 810 to rotate through the nozzle coupling 802, squeezes the material from the heat pipe 806 to the connecting tube 807, and finally squeezes it out from the nozzle 808 onto the hot bed 6, and the printing function begins.

[0044] like Figure 8As shown, the material device 3 includes a material barrel 310 and a material extrusion shaft 307. The material barrel 310 is installed on the body frame through the material support frame 21. The material extrusion shaft 307 is rotatably installed in the material barrel 310. The material extrusion shaft 307 has spiral blades. The material barrel 310 is provided with a discharge port 308 and a feed port 309. The lower end of the discharge port 308 is connected to the nozzle inlet 805 through a hose 15. The hose 15 is installed on the discharge port 308 through a first flange 22. A heating part 311 is also provided on the barrel wall of the material barrel 310.

This hose 15 is connected to the discharge port 308 through a first flange 22 to ensure sealing and transportation stability. In addition, a heating part 311 is provided on the barrel wall of the material barrel 310, and its function is to control the melting state of the material by heating to ensure that the material can pass through the nozzle smoothly.

[0046] A boss 306 is installed at the upper end of the material barrel 310, a deep groove ball bearing 305 is installed between the material extrusion shaft 307 and the boss 306, a material end cover 304 is installed at the upper end of the boss 306, a support barrel 303 is installed on the material end cover 304, a material motor 301 is installed on the support barrel 303, and the material motor 301 is connected to the material extrusion shaft 307 through a material coupling 302.

[0047] A deep groove ball bearing 305 is installed between the material extrusion shaft 307 and the boss 306, which can effectively reduce friction, improve rotation accuracy, and ensure the high efficiency and stability of the material extrusion shaft 307 during operation. The material motor 301 is installed on the support cylinder 303, connected to the material extrusion shaft 307 through the material coupling 302, and drives the material extrusion shaft 307 to rotate, thereby pushing the material to be output through the material cylinder 310.

[0048] The two material barrels 310 are fixed on the first side plate 4. The material enters the material barrel 310 from the feed port 309. The material motor 301 works and drives the material extrusion shaft 307 to rotate through the material coupling 302. The deep groove ball bearing 305 ensures the stability of the extrusion shaft rotation. The boss 306 separates the barrel body from the upper motor support seat 10 to prevent the material from flying out of the upper end of the barrel body. The spiral extrusion shaft 810 can squeeze the material in the material barrel 310 downward. The end of the material barrel 310 is connected to the first flange 22. The material enters the hose 15 through the first flange 22 and finally enters the nozzle device 80, thus completing the material conveying work.

[0051] like Figure 1 As shown, a mounting seat is provided on the top cover 1, and the upper end of the electric telescopic rod 9 is mounted on the mounting seat. The design of the mounting seat enables the electric telescopic rod 9 to stably perform telescopic movement without being interfered by other components, thereby improving the stability and accuracy of the device, thereby ensuring the continuity and accuracy of the colloid delivery process.

[0052] During operation, the colloid used enters the colloid device 70 from the colloid inlet 701. When the electric telescopic rod 9 moves downward, the rubber plug will push the colloid to move downward stably, squeeze the colloid contained in the colloid device 70 into the hose 15, and finally enter the nozzle from the nozzle part feed port 309, thereby completing the work of conveying the colloid.

[0053] In summary, the integrated parts processing equipment based on 3D printing technology provided in this embodiment breaks through the limitations of traditional manufacturing processes and realizes integrated additive manufacturing of multi-material parts. The equipment effectively solves technical problems such as high cost and complex process in the production of composite parts, and significantly improves production efficiency and reduces manufacturing costs through innovative process routes.

[0054] The nozzle device 80 provided in this embodiment adopts an innovative spiral extrusion mechanism design. The spiral push rod rotates precisely in the temperature-controlled heat pipe 806 to ensure uniform transportation and density of the material.

This design significantly improves the process adaptability of the equipment and greatly expands the potential application scenarios.

[0056] The colloid device 70 for storing rubber material provided in this embodiment adopts a precision extrusion solution driven by an electric telescopic rod 9, ensures stable delivery of rubber material through a special rubber plug design, and accurately controls the motion parameters of the electric telescopic rod 9 to realize in-situ forming of rubber seals. This integrated manufacturing process significantly simplifies the manufacturing and assembly process of seals, while improving the overall performance and reliability of the sealing structure, and provides greater freedom for the innovative design of internal combustion engine parts.
