Description

Technical Field

[0001] This utility model mainly relates to the field of liquid metal printing technology, specifically a liquid metal printing nozzle. Background Technology

[0002] Existing nozzles are mostly single funnel-shaped machining parts and long strip-shaped boat-shaped porous structures. Neither of these structures can be well combined to meet the fine and dense nozzle requirements of printing. They often require multiple rows of arrays, which widens the printing impact area and affects the printing effect. The installation and sealing of these two types of nozzles are also relatively troublesome. They require conical surface sealing and can only be drilled after installation to ensure the hole spacing. The operation is complicated, inefficient, and has high processing costs. In addition, impurities accumulate at the nozzle orifice during the printing process. Fine inclusions in the solute accumulate at the nozzle orifice, which can cause risks such as jet deflection and orifice blockage, especially in magnesium alloy printing. Utility Model Content

[0003] To achieve the above objectives, this utility model employs the following technical solution: A liquid metal printing nozzle includes a mounting base, on the top of which a nozzle protrusion is fixedly disposed, and nozzles are arrayed on the nozzle protrusion. The nozzle protrusion has a triangular cross-section.

[0004] The nozzle penetrates the mounting base and the nozzle protrusion.

[0005] Compared with the existing technology, the beneficial effects of this utility model are: This utility model has a simple structure, is easy to install and use, and can improve the efficiency of operation and installation after installation. It simplifies the installation process, is quick and easy to replace, does not require cleaning, can ensure smooth printing, reduce hole blockage and jet deflection, improve printing success rate, and achieve cost reduction and efficiency improvement.

[0007] The labels in the attached diagram are: 1. Mounting base; 2. Nozzle protrusion; 3. Nozzle. Detailed Implementation

[0008] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0009] Referring to the accompanying drawings, a liquid metal printing nozzle includes a mounting base 1, on the top of which a nozzle protrusion 2 is fixedly disposed, and nozzles 3 are arrayed on the nozzle protrusion 2. The nozzle protrusion 2 has a triangular cross-section.

[0010] The nozzle 3 penetrates the mounting base 1 and the nozzle protrusion 2.

[0011] The flat-plate design allows for precise nozzle arrangement, achieving the required fineness without the need for multiple rows; a single row suffices. The overall machining accuracy of the nozzles is well-assured, allowing for single-installation. The seal consists of ceramic fiber cotton sandwiched along the edge of the raised upper surface, with a heat-insulating pressure plate on the lower surface. This sealing structure is simple to operate, provides excellent sealing, and boasts high installation efficiency. The raised nozzle reduces the impact of solute inclusions on the jet, improving printing efficiency and success rate. Inclusions are unlikely to remain on the sharp protrusions and will fall below for collection.

[0012] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
