Description

Technical Field

[0001] The utility model relates to the technical field of 3D forming, in particular to an insulating material extrusion device for 3D forming. Background Art

[0002] 3D forming, also known as additive manufacturing, is a technology that forms three-dimensional entities by layer-by-layer stacking of materials. It is very different from traditional subtractive manufacturing technologies, which form the required shape by cutting or grinding materials. 3D printing technology can produce objects with complex shapes and internal structures, which are often difficult to achieve by traditional manufacturing methods.

[0003] When the existing 3D forming and printing device extrudes materials, it usually pre-heats and softens the materials in advance to make them flow. However, during the material transportation process, the heat is quickly consumed, which may cause the materials to solidify when they are transported to the extrusion head, seriously affecting the subsequent extrusion forming process. And when the materials solidify inside the extrusion head, it will be relatively difficult to clean. Summary of the Utility Model

[0025] Please refer to Figures 1-4 , a kind of insulating material extrusion device for 3D forming of the present invention includes an extrusion tube 1. The extrusion tube 1 is the main extrusion structure of the device and is used for extruding insulating materials. An extrusion head 2 is arranged below the extrusion tube 1, that is, extrusion is carried out at the extrusion head 2. A threaded port 21 is arranged at the top of the extrusion head 2, and a threaded groove 12 is arranged at the bottom of the extrusion tube 1. The threaded port 21 and the threaded groove 12 are in threaded connection. A sealing ring 23 is arranged at the top of the threaded port 21. That is, the extrusion head 2 is installed by connecting the threaded port 21 to the threaded groove 12, and the sealing ring 23 is attached to the top of the threaded groove 12, so as to achieve a good installation effect. Conversely, for disassembly, it is convenient to clean the extrusion head 2 and effectively avoid blockage. On the other side of the extrusion tube 1, there is a mounting part 22. Connecting ports 24 are arranged on both sides of the mounting part 22. The mounting part 22 is a mounting structure, and the extrusion tube 1 is fixedly installed on the mounting part 22, that is, the whole device is installed through the connecting ports 24.

[0026] On one side of the extrusion tube 1, there is a pusher tube 3. At the top of the pusher tube 3, there is a feed tube 32. Above the feed tube 32, there is a connecting tube 33, and the connecting tube 33 is used to connect the feeding pipeline of the insulating material, so that the insulating material enters the pusher tube 3 through the feed tube 32. On one side of the feed tube 32, there is an electric valve 34, that is, the electric valve 34 is used to open and close the feed tube 32. Inside the pusher tube 3, there is a pushing member 4. Outside the pusher tube 3, there is an electric push rod 43, and the electric push rod 43 is connected to the rear side of the pushing member 4. When there is insulating material in the pusher tube 3, the electric push rod 43 is used to push the pushing member 4, so as to push the insulating material into the extrusion tube 1. Since the surface of the pushing member 4 is inclined, it can prevent the insulating material from falling behind the pushing member 4. On both sides of the pushing member 4, there are limiting grooves 41, and on both sides inside the pusher tube 3, there are limiting strips 42. The limiting grooves 41 and the limiting strips 42 are in sliding connection, and the limiting strips 42 are used to limit the limiting grooves 41, so that the pushing member 4 can maintain stability when sliding.

[0027] Inside the extrusion tube 1, there is a rotating shaft 13. Outside the rotating shaft 13, there are spiral blades 14. At the top inside the extrusion tube 1, there is an installation opening 15. At the top of the rotating shaft 13, there is a mounting bolt 11, and the mounting bolt 11 is movably connected to the installation opening 15, that is, the mounting bolt 11 is stuck in the installation opening 15 and rotates. At the top of the installation opening 15, there is a motor 31, and the motor 31 is connected to the mounting bolt 11, that is, the motor 31 drives the mounting bolt 11 to rotate, so that the rotating shaft 13 drives the spiral blades 14 to rotate, thereby extruding the insulating material. Inside the pushing member 4, there is a heating block 45. At the bottom of the pusher tube 3, there is a heating plate 5. At the rear side of the heating block 45, there is a first electric wire connection 52, and at the bottom of the heating plate 5, there is a second electric wire connection 51, that is, the heating block 45 and the heating plate 5 are powered on through the first electric wire connection 52 and the second electric wire connection 51, so as to generate heat, prevent the insulating material inside from solidifying, and ensure the extrusion efficiency. Below the rear side of the pushing member 4, there is a wire passing opening 44, and the first electric wire connection 52 passes through the wire passing opening 44.

[0028] The working principle of the present utility model is as follows: The extrusion head 2 is installed by connecting the threaded port 21 to the threaded groove 12, and the sealing ring 23 is attached to the top of the threaded groove 12 to achieve a good installation effect. Conversely, for disassembly, it is convenient to clean the extrusion head 2. The feeding pipeline of the insulating material is connected through the connecting pipe 33, so that the insulating material enters the pushing pipe 3 through the feeding pipe 32. The feeding pipe 32 is opened and closed by the electric valve 34. When there is insulating material in the pushing pipe 3, the pushing member 4 is pushed by the electric push rod 43, so as to push the insulating material into the extrusion pipe 1. Since the surface of the pushing member 4 is inclined, it is avoided that the insulating material falls behind the pushing member 4. The limiting strip 42 limits the limiting groove 41, so that the pushing member 4 remains stable during sliding. By energizing the heating block 45 and the heating plate 5, heat is generated to prevent the internal insulating material from solidifying, thus ensuring the extrusion efficiency. The motor 31 drives the mounting bolt 11 to rotate, so that the rotating shaft 13 drives the spiral blade 14 to rotate, and the insulating material is extruded, that is, extrusion is carried out at the extrusion head 2.
