Description
Technical field
The utility model relates to 3D printing technique field, in particular to the 3D printer nozzle that a kind of homogeneous heating is stable.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
Generally have the heat block for heater strip material in the nozzle structure of 3D printer, but in heat block, temperature distributing disproportionation is even, causes the silk material in shower nozzle to melt also unshapeliness, occurs block, impact effect.
Utility model content
The purpose of this utility model is the 3D printer nozzle providing a kind of homogeneous heating stable, to solve the problem.
For realizing the utility model object, the technical scheme of employing is: the 3D printer nozzle that a kind of homogeneous heating is stable, and comprise the vertical nozzle body, the heating jacket be set in outside nozzle body that arrange, the lower end of nozzle body stretches out in heating jacket; The outer surface of nozzle body and the inner surface of heating jacket are provided with the screw thread of coupling mutually; The end face of heating jacket offers the uniform heating blind hole of circumference, is provided with heating element heater in heating blind hole; Nozzle body offers material hole, and material hole is made up of the positive round taper hole of the rounding taper hole on top, the cylindrical hole at middle part and bottom; Nozzle body lower end offers the extrusion cavities communicated with positive round taper hole; Nozzle body is also arranged with instlated tubular and radiating tube outward, and instlated tubular is between radiating tube and heating jacket, and instlated tubular and radiating tube are threaded, and radiating tube outer surface cloth is provided with fin.
Further, the top inner wall of described heating blind hole is provided with non-return projection.
Further, described heating blind hole is four.
The beneficial effects of the utility model are, the heating element heater uniform by heating jacket heats, and heating jacket and nozzle body are threaded connection, more be beneficial to and transfer heat to nozzle body, heat transmission is even, thermal-stable, and it is attractive in appearance, and material hole defines the material extrusion passage that can accelerate raw material flow rate, avoid material Kong Shanghui retained material maybe the situation extruding channel blockage to be occurred, improve operating efficiency, the setting of radiating tube and instlated tubular, can prevent the upper end consumptive material in nozzle body from softening too early, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the sectional view of the 3D printer nozzle that homogeneous heating that the utility model provides is stable;
Fig. 2 is the top view of the heating jacket that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the stable 3D printer nozzle of homogeneous heating that the utility model provides, and comprise the vertical nozzle body 1, the heating jacket 2 be set in outside nozzle body 1 that arrange, nozzle body 1 stretches out in heating jacket 2; The outer surface of nozzle body 1 and the inner surface of heating jacket 2 are provided with the screw thread of coupling mutually; The end face of heating jacket 2 offers the uniform heating blind hole 21 of circumference, is provided with heating element heater in heating blind hole 21; Nozzle body 1 offers material hole, and material hole is made up of the positive round taper hole 13 of the rounding taper hole 11 on top, the cylindrical hole 12 at middle part and bottom; Nozzle body 1 lower end offers the extrusion cavities 14 communicated with positive round taper hole 13; Nozzle body 1 is outer is also arranged with instlated tubular 3 and radiating tube 4, instlated tubular 3 is between radiating tube 4 and heating jacket 2, instlated tubular 3 and radiating tube 4 are threaded, and radiating tube 4 outer surface cloth is provided with fin, and fin also can be arranged in the periphery of radiating tube 4 in spline-like.
Heating blind hole 21 is four, can meet conventional demand, ensures the uniformity of heating.The top inner wall of heating blind hole 21 is provided with non-return projection, fixing after heating element heater is installed, and prevents from dropping out, installs and also facilitate.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
