Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and more particularly to a mold structure for 3D printing water channels by grafting metal. Additionally, it relates to a method for preparing a mold structure for 3D printing water channels by grafting metal. Background Technology

[0002] When designing water channels in a mold, it's best to achieve complete coverage of the product and uniform channel spacing. Therefore, using metal powder for 3D printing water channels is an excellent solution. However, printed metal often suffers from defects such as pitting and impurities due to varying manufacturing processes, resulting in poor polishing performance. Therefore, metal grafting is often necessary. Achieving conformal water channels to the product's shape during metal grafting is a significant technical challenge.

[0003] Using conventional all-metal powder 3D printing methods can result in micropores, particles, and pits on the product surface due to the printing materials.

[0004] However, the design structure of the grafted steel is not sufficiently optimized when using metal grafting printing. The water channel can only rotate and wind within a single plane, making it impossible to achieve uniform cooling of the thick-walled lens surface.

[0005] In view of this, it is necessary to design a mold structure for grafting metal to 3D print water channels in order to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0007] Therefore, the present invention provides a mold structure for grafting metal to 3D print water channels, which can reasonably divide the mold core and, combined with a polygonal base, repeatedly position and achieve the encapsulation of metal grafting printing.

[0008] According to a first aspect of the present invention, a mold structure for 3D printing water channels by grafting metal includes a mold core and a grafting base. The mold core has an optical surface corresponding to the product. The optical surface is the metal overlap portion of the mold core and the grafting base. One side of the grafting base extends beyond the product by at least 4 mm, and the opposite sides of the grafting base are parallel.

[0009] Preferably, the grafting base has a polygonal structure, and mounting screw holes are provided on at least three sides of the grafting base to fix the grafting base through the mounting screw holes.

[0010] More preferably, the thickness of the overlapping metal portion of the mold core and the grafting base is at least 4 mm.

[0011] Preferably, the mold core is formed by combining multiple additive manufacturing parts, and each of the multiple additive manufacturing parts is made with different positioning surfaces on the grafting base as reference surfaces.

[0012] More preferably, the mold core includes a first additive component, which is made with the first positioning surface of the grafting base as a reference surface, and the first positioning surface is the plane where one of the inclined sides of the grafting base is located.

[0013] Preferably, the mold core includes a second additive part, which is made with the second positioning surface of the grafting base as a reference surface, and the second positioning surface is symmetrically arranged with the first positioning surface.

[0014] More preferably, the mold core includes a third additive part, which is made with the third positioning surface of the grafting base as a reference surface, and the third positioning surface is a polygonal plane in the front view of the grafting base.

[0015] Preferably, the mold core includes a fourth additive part, which is made with the fourth positioning surface of the grafting base as a reference surface, and the fourth positioning surface is disposed opposite to the third positioning surface.

[0016] More preferably, the mold core includes a fifth additive component, which is made with the fifth positioning surface of the grafting base as a reference surface. The fifth positioning surface is composed of a first positioning surface, a second positioning surface, and a fifth structural surface disposed between the first positioning surface and the second positioning surface.

[0017] The second aspect of this invention provides a method for constructing a mold structure for 3D printing water channels by grafting metal, applicable to the mold structure for 3D printing water channels by grafting metal described in the first aspect of this invention. This method includes the following steps:

[0018] Multiple positioning surfaces are set on the grafting base;

[0019] Multiple additive parts required for mold core assembly are manufactured using each positioning surface as a reference surface;

[0020] The resulting additive parts are assembled to form a complete mold core.

[0021] The beneficial effects of this invention are as follows: by reasonably dividing the printing mold core and combining it with a polygonal base, the grafting base printing is achieved by repeatedly positioning the parts; through multiple grafting printings, the printed grafting base parts are combined into complete parts on various positioning surfaces of the grafting base, without the need to modify the metal printing equipment, thus realizing the 3D stereoscopic printing of each part of the grafting base, and without changing the operating procedures of the original metal printing equipment operators.

The objects and other advantages of the invention are realized and obtained in accordance with the structures particularly pointed out in the description, claims and drawings.
