Problems solved by technology

[0002] Although the existing 3D printing technology can produce mold inserts with conformal water channels inside, in order to ensure the strength of the workpiece, the wall thickness from the water channel to the edge of the workpiece needs to ensure a certain size. If the wall thickness from the water channel to the edge of the workpiece is relatively Thin, the service life of the workpiece will be greatly reduced

Embodiment Construction

[0020] 3D printing: 3D printing technology is also called additive manufacturing technology, laser accumulation technology or laser rapid prototyping technology. ways to construct objects

[0021] Mold: refers to a tool that uses its own specific closed cavity to form three-dimensional plastic products with a certain shape and size

[0022] This application provides a composite high thermal conductivity metal 3D printing method, in which high thermal conductivity materials are added to parts of mold inserts that cannot be provided with conformal waterways due to their small size, so as to increase heat conduction at smaller parts.

[0023] The specific steps are:

[0024] 1. Select the printing powder 420, and the printing powder must be sieved through a sieve of 300 mesh or more.

[0025] 2. Powder drying treatment.

[0026] 3. Fill the powder into the powder filling bin of the printer and plug it tightly.

[0027] 4. Install the printing plate to the printer.

[0028] 5...

Abstract

The invention discloses a composite high-thermal-conductivity metal 3D printing method. The composite high-thermal-conductivity metal 3D printing method comprises the following steps that 1) printingpowder 420 is selected, and needs to be screened by a screen of 300 meshes or above; 2) the powder is dried; and 3) the powder fills a powder filling bin of a printer to be compacted. According to theprovided composite high-thermal-conductivity metal 3D printing method, the heat conduction of the portion, which cannot be provided with a conformal water path due to the relatively small size, of amold insert is increased, the forming period of a product is shortened, the yield of the product in unit time is increased, and the productivity is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method of a composite high thermal conductivity metal, which is mainly applied to mold inserts that need to be cooled in the mold field. Background technique [0002] Although the existing 3D printing technology can produce mold inserts with conformal water channels inside, in order to ensure the strength of the workpiece, the wall thickness from the water channel to the edge of the workpiece needs to ensure a certain size. If the wall thickness from the water channel to the edge of the workpiece is relatively Thin, the service life of the workpiece will be greatly reduced. Contents of the invention [0003] This application provides a composite high thermal conductivity metal 3D printing method, which can increase the heat conduction of the parts of the mold insert that cannot be equipped with a conformal waterway due to its small size, reduce the molding cyc...
