Technical field
The utility model is related to 3D printer technical field, specially a kind of new FDM formulas 3D printer material leak-proof nozzle.
Background technology
3D printer is also known as three-dimensional printer, is a kind of machine of a kind of accumulation manufacturing technology, i.e. RP technique, it
Based on being a kind of mathematical model file, with special wax material, powdery metal or plastics etc. can jointing material, pass through printing one
Jointing material layer by layer come manufacture three-dimensional object.Three-dimensional printer is used to manufacture product at this stage.The mode successively printed
Carry out the technology of constructed object.The principle of 3D printer is that data and raw material are put into 3D printer, and machine can be according to program handle
Product is created from level to level.3D printing brings worldwide manufacturing industry revolution, is that part design places one's entire reliance upon production work in the past
Artistic skill is no to be realized, and the appearance of 3D printer, it will overturn this production thinking.
Heating extruding part used in current FDM formula 3D printers is largely divided into 3 part compositions：Nozzle, instlated tubular,
Heating module, these three parts coordinate to be coordinated using screw thread, i.e., heating module part is internal thread, and nozzle and instlated tubular are outer
Screw thread, common process can not be too high to sealing grade or cost up to screw thread, and step is complex when assembling, and frequently results in
The material that printer work a period of time has molten condition is leaked out, and prevents printing from being normally carried out.
Utility model content
The purpose of this utility model is to provide a kind of new FDM formulas 3D printer material leak-proof nozzle, to solve the above-mentioned back of the body
The common process proposed in scape technology can not be too high to sealing grade or cost up to screw thread, and step is more multiple when assembling
Miscellaneous, frequently resulting in printer work a period of time has the material of molten condition and leaks out, and prevents printing from being normally carried out.
To achieve the above object, the utility model provides following technical scheme：A kind of new FDM formulas 3D printer material leak-proof
It is provided with sealing threaded body above nozzle, including heating module, the heating module, the sealing threaded body is internally embedded
Instlated tubular is installed, the instlated tubular is internally provided with catheter hub, and the inside penetrability of the heating module is provided with spiral shell
Pit, and the inside of heating module is provided with nozzle, the inner hub location of the nozzle is provided with melting leakproof pipeline.
It is preferred that, the inside of the screwed hole is provided with secret screw, and the secret screw connects with screwed hole threaded engagement
Connect.
It is preferred that, the nozzle is connected with heating module by gap screens.
It is preferred that, the nozzle is connected with sealing threaded body by interference interface.
It is preferred that, the outer surface of the sealing threaded body is helicitic texture.
Compared with prior art, the beneficial effects of the utility model are：The utility model scientific structure design is rationally assembled
It is convenient, the problem of the utility model is for current FDM formulas 3D printer heating extrusion module material leakage, by processing and assembling
Further analysis, makes nozzle be engaged with instlated tubular, nozzle is used hole axle with heating module using interference fit interface
Gap be connected, and nozzle is fixed with heating module using machine-processed rice screw, efficiently solves material leakage problem, reduce work
Skill manufacture difficulty, reduces production cost and period, and practical performance is strong, is easy to marketing.
