3D printing extrusion nozzle based on industrial design field

Abstract

The invention provides a 3D printing extrusion nozzle based on the industrial design field, relates to the field of printing extrusion nozzles, and aims to solve the problems that when an existing 3D printing extrusion nozzle is used, after printing is completed, residual materials are likely to appear at an outlet position, and if cleaning is not conducted in time, blockage is likely to be caused. The 3D printing extrusion nozzle comprises a body. The body is a 3D printing extrusion nozzle body, the interior of the body is of a cylindrical structure, and a sealing piece is installed at the top end of the body. When materials pass through, a moving head is pushed to move downwards, the bottom of the moving head is of a conical structure and can be inserted into a conical groove of a partition plate, the partition plate is pushed to move towards the two sides, the bottom of a bottom head can be automatically opened, the moving head can be located on the outer side of the bottom of the bottom head to spray out the materials, after printing is completed, the materials are not discharged any more, a flow dividing piece is not pressed any more, a spring pushes a moving head to move upwards, meanwhile, the partition plate receives power of the spring to reset, and the residual materials 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
