Embodiment 1

[0042] A processing method for 3D printing PVD moulds, comprising the following steps:

[0043] A: Modeling; scan the mold prototype and the conformal waterway 11 through a 3D scanning device to obtain the 3D dimensions, import the 3D dimensions to the computer client and process them to obtain a 3D digital model, and import the 3D digital model file into the 3D printing molding device Terminal, set printing parameters;

[0044] B: Add material: Lay the alloy powder on the working platform of the 3D printing molding equipment to obtain the powder working layer, and then choose to execute the printing function. The 3D printer performs laser scanning on the powder working layer, so that the alloy powder in the scanned area is melted and solidified. Laser sintering processing technology is used to process the material layer by layer, and the conformal waterway 11 changes with the shape of the part model. The working room of the laser scanning is an inert atmosphere, and the laser...

Abstract

The invention discloses a 3D printing PVD mold, and relates to the technical field of 3D printing. The 3D printing PVD mold comprises a mold body, the mold body is T-shaped, the surfaces of the two sides of the mold body are provided with conformal water paths, and a coating is arranged on the surface of the mold body. The invention further discloses a printing method of the 3D printing PVD mold.The printing method comprises the following steps of A, establishing a model; B, carrying out additive manufacturing; C, polishing; D, carrying out surface treatment; and E, coating. According to the3D printing PVD mold, the changeable water paths can be designed according to the shape of the mold, the newest 3D printing technology is adopted instead of a conventional drilling process, the product can achieve the most effective cooling in a short time, the production efficiency is greatly improved, and the product cost is reduced; and the prepared mold is high in precision, low in roughness,high in density, higher in hardness than a forged piece, and the tensile strength is superior to that of a casting.

Description

technical field [0001] The invention relates to the technical field related to 3D printing, in particular to a 3D printing PVD mold and a method thereof. Background technique [0002] Technological progress drives the vigorous development of various products, and the product development cycle is relatively shortened. In order to increase the mass production value within a limited time and at the same time take into account the quality of the product, by improving the heat dissipation efficiency of the mold to reduce the cooling stage in the molding cycle, it becomes injection molding. An important means in the molding process. [0003] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold man...
