Embodiment 1

[0050] This embodiment provides a preparation process for castings based on 3D printing technology, including the following process steps:

[0051]Utilize three-dimensional software to design the pouring mold model, convert the pouring mold model into STL data format, and import it into the slicing software for slicing processing, the layer thickness is 0.05mm, and the wall thickness of the pouring mold model is 0.5mm, and the pouring mold is obtained. 3D model data;

[0052] Then import the obtained three-dimensional model data of the casting mold into the 3D printing device, and print and form the casting mold;

[0053] Finally, the fluid raw material is injected into the cavity of the above casting mold to obtain the casting.

[0054] The above-mentioned fluid raw materials are silica gel and curing agent, and are prepared according to the mass ratio of 100:3.5.

[0055] At the same time, the prepared fluid is also vacuumized before being injected into the casting mold: p...

Embodiment 2

[0063] This embodiment provides a preparation process for castings based on 3D printing technology, including the following process steps:

[0064] Utilize three-dimensional software to design the pouring mold model, convert the pouring mold model into STL data format, and import it into the slicing software for slicing processing, the layer thickness is 2mm, the wall thickness of the pouring mold model is 1mm, and the three-dimensional model of the pouring mold is obtained data;

[0065] Then import the obtained 3D model data of the casting mold into the 3D printing equipment, and put acrylonitrile-butadiene-styrene copolymer as the printing material; after coating the printing surface of the printing base with glue, print the casting mold It is formed by light curing; the molded casting mold is polished to make the inner surface of the cavity of the casting mold form a smooth layer;

[0066] Finally, inject the fluid raw material that has been evacuated into the cavity of t...

Embodiment 3

[0072] Such as figure 1 and Figure 4 As shown, according to the 3D printing technology of embodiments 1 and 2, this embodiment provides a casting mold, which includes: a cavity wall and a cavity 107 surrounded by the cavity wall, and the wall thickness of the cavity wall 1mm.

[0073] Preferably, the cavity coaming comprises a bottom plate 101, a side coaming 102 and a cover plate 104; the cover plate 104 is provided with an injection hole 103 and an overflow hole 105, and the injection hole 103 and the overflow hole 105 are respectively communicated with the cavity 107 ; The inner surface of the cavity 107 is a smooth layer, and the smooth layer is provided with a release agent layer.

[0074] Such as figure 2 As shown, the outer surface of the cavity coaming has laminations 106, and the distance between two adjacent laminations 106 is 0.05mm; the interior of the cavity coaming is filled with honeycomb.

[0075] As a preferred solution of this embodiment, such as imag...

Abstract

The invention provides a preparation process and a casting mould for a cast product based on the 3D printing technology, and belongs to the technical field of mould processing. The preparation process comprises the following steps: A, designing a casting mould model by utilizing a three-dimensional software, converting the casting mould model into a STL data format, leading the STL data format into a slicing software to carry out slicing processing, enabling a thickness of a laminate sheet to be 0.01-2mm, and enabling the wall thickness of the casting mould model to be greater than or equal to 0.5mm, thereby obtaining three-dimensional model data of the casting mould; B, leading the three-dimensional model data, obtained in the step A, of the casting mould into 3D printing equipment, carrying out printing and molding, thereby obtaining the casting mould; and C, injecting a fluid raw material into a mould cavity of the casting mould in the step B, thereby obtaining the cast product. The casting mould comprises mould cavity surrounding boards, and a mould cavity defined by the mould cavity surrounding boards, wherein an injection hole and an overflow hole are formed in the top of each mould cavity surrounding board. The preparation process and the casting mould has the advantages such as high processing precision, less material consumption, high production efficiency, simple manufacturing processes, low production cost and the like.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a preparation process of a casting based on 3D printing technology and a casting mold. Background technique [0002] 3D printing technology belongs to a kind of rapid prototyping technology. It is a technology based on model files to construct objects by layer-by-layer stacking and stacking. At present, 3D printing technology is widely used in various fields. [0003] However, the existing molds are mainly processed and manufactured by CNC (numerical control machine tools), which have the disadvantages of consuming materials, complex procedures, and high production costs. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to provide a preparation process and casting mold for castings based on 3D printing technology, so as to save consumables, reduce manufacturing processes, and reduce production costs. [00...
