Embodiment 1

[0032] Such as figure 1 Shown is a schematic diagram of the product to be cast in this embodiment; the invention provides a method for dieless forming casting of an aluminum alloy casting, which specifically includes the following steps:

[0033] (1) Preprocess the three-dimensional image of the product, that is, to figure 1 Carry out preprocessing, delete the subtle features that cannot be cast and form, increase the machining allowance on the processing surface, shrink the model as a whole, design the gating system according to the product structure characteristics and complete the three-dimensional graphics drawing of the gating system, and obtain the casting process diagram of the product, such as figure 2 shown;

[0034] Then use the 3D software to draw the 3D model of the sand shell;

[0035] (2) Use a 3D printer to print out the drawn casting sand molds, as follows image 3 The 3D printing sand mold for the product to be cast is shown; as Figure 4 The upper mold o...

Abstract

The invention belongs to the technical field of metal material machining and forming and particularly relates to a mold-free formation casting method of a high-performance aluminum alloy casting. Themold-free formation casting method comprises the steps that a shell mold is rapidly manufactured by the adoption of a 3D printing technology, box burying and tamping are conducted in a V-method shaping manner, and then a low-pressure technology is adopted to conduct pouring. According to the implementation scheme, the problem that by the adoption of a traditional casting technology, precise casting of a complicated large-sized metal component and a small batch of individualized products is quite difficult to achieve, a near-net forming technology is achieved, the product quality of the castingis greatly improved, the production and manufacturing environment is improved, the labor intensity is lowered, and environment-friendly casting basically can be achieved. Besides, by the adoption ofthe mold-free formation casting method of the high-performance aluminum alloy casting, the product can achieve that the structure is more complicated, the performance is more excellent, the quality ismore elaborate, manufacturing is more efficient and the cost performance ratio is more reasonable, and the product has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of metal material processing and molding, and in particular relates to a moldless molding casting method for high-performance aluminum alloy castings. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal material in the industry. It has the characteristics of low density, high strength, good plasticity, corrosion resistance, and excellent electrical and thermal conductivity. It is used in automobiles, molds, mechanical equipment, ships, aerospace, and national defense. Military industry and other industries occupy a very important position, and it is one of the main structural materials to realize industrial lightweight. [0003] In the prior art, due to the wide variety, single quantity and structural differences, there are disadvantages such as unreasonable process design and manufacturing, large machining allowance of castings, and irregular structural design for personal...
