Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum extrusion dies, and in particular relates to a novel aluminum extrusion die. Background Art

[0002] Aluminum extrusion dies are an indispensable and important tool in the aluminum processing process. They are responsible for accurately extruding aluminum into profiles of various shapes and sizes. With the rapid development of the aluminum market and the continuous advancement of aluminum extrusion technology, the application field of aluminum extrusion dies is becoming increasingly extensive. Aluminum extrusion dies are made of high-quality metal and have precisely designed channels inside. During the extrusion process, aluminum is shaped into profiles of the required shape and size through the corresponding channels.

[0003] Although the aluminum extrusion die in the prior art can meet the general usage requirements, the aluminum extrusion die is in contact and friction with the aluminum material for a long time during use, which will cause wear and residue on the surface, and the process of mold opening and demolding is also a key step. This process is relatively cumbersome and requires frequent use of fine gauze paper and grinding tools to comprehensively repair the residues on the mold. Not only is the operation very cumbersome and time-consuming, but it also affects the accuracy and stability of the mold and shortens the service life of the mold. Therefore, its applicability and practicality are limited. Summary of the invention

[0004] The utility model aims to provide a novel aluminum extrusion die with reasonable structure and strong stability in use.

[0005] The technical solution for achieving the purpose of the utility model is a novel aluminum extrusion die, comprising a lower die body and an upper die body, wherein the top surface of the lower die body is provided with a welding chamber, and the middle part of the bottom wall of the welding chamber is provided with a working belt;

[0006] A mold core is integrally formed in the middle of the bottom surface of the upper mold body, and a plurality of diversion holes penetrating from top to bottom are arranged on the upper mold body, and the plurality of diversion holes are evenly arranged at the edge of the mold core, and a diversion bridge is formed between adjacent diversion holes;

[0007] The surfaces of the upper mold body, the lower mold body, the mold core, the diversion hole, the diversion bridge, the welding chamber and the working belt are provided with a titanium coating layer.

[0008] More preferably, the thickness of the titanium plating layer is 5-25 um.

[0009] More preferably, the titanium plating layer is formed by electroplating.

[0010] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a titanium plating layer is arranged on the surface of the upper mold body, the lower mold body, the mold core, the diversion hole, the diversion bridge, the welding chamber and the working belt. The titanium plating layer can not only improve the surface hardness, but also has excellent lubrication performance, which is beneficial to reduce the friction coefficient, thereby reducing the wear of the mold. At the same time, it has good corrosion resistance and high-temperature oxidation resistance, which is beneficial to use in high temperature, high humidity and strong corrosive environments, and is beneficial to improving the stability and reliability of the overall structure. It has strong applicability and good practicality. BRIEF DESCRIPTION OF THE DRAWINGS
