A 3D printing extrusion nozzle based on the field of industrial design

Abstract

The present invention provides a 3D printing extrusion nozzle based on the field of industrial design, which relates to the field of printing extrusion nozzles, to solve the problem that when the existing 3D printing extrusion nozzles are in use, residues are likely to appear at the exit position after printing. If it is not cleaned up in time, it will easily cause clogging, including the main body; the main body is the body of the 3D printing extrusion nozzle, and the inside of the main body is a cylindrical structure, and the top of the main body is equipped with a seal. When the material passes through, push the moving head to move downwards. The bottom of the moving head is a conical structure, which can be inserted into the tapered groove of the partition plate, and push the partition plate to move to both sides, so that the bottom of the bottom head can be automatically opened. , so that the moving head can be placed outside the bottom of the bottom head to eject the material. After the printing is completed, the material is no longer discharged, and the shunt is no longer under pressure. The spring pushes the moving head to move upward, and the partition plate receives the power of the spring to reset. Residual material can be cut off.

Description

technical field [0001] The invention belongs to the technical field of printing extrusion nozzles, and more specifically relates to a 3D printing extrusion nozzle based on the field of industrial design. Background technique [0002] When doing industrial design, it is usually necessary to use a 3D printer to print out the model, and the 3D printer needs to use a 3D printing extrusion nozzle to extrude the material into shape. [0003] For example, the application number: CN201910576251.7 relates to an extruded biological 3D printing nozzle, including a motor 12 that can drive the rotary valve to rotate through a coupling. In the installation hole of the rotary valve, when the rotary valve rotates, the inlet of the flow channel can be connected with n outlets in turn, a magnetic plate is arranged on the outside of the connecting plate, and an electromagnet is arranged on the installation surface of the nozzle mounting seat. When the electromagnet When the power is off, the ...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a 3D printing extrusion nozzle based on the field of industrial design to solve the problem that when the existing 3D printing extrusion nozzle is in use, the sealing effect of the connection is poor, and it is easy to appear after a long time of use. The high temperature causes damage to the rubber sealing gasket, and when the existing 3D printing extrusion nozzle is in use, after the printing is completed, residual material is likely to appear at the outlet position. The particles produced by the material not melting completely will easily lead to the failure of the printed model
