Problems solved by technology

[0002] For products with high precision requirements, large external dimensions, high appearance requirements and complex structures, although traditional machine tool processing methods can be achieved, what the machine tool obtains is a rough embryo, and the rough embryo to the product requires rough machining and finishing. There are too many machining allowances and waste of materials; and it takes man-hours for processing and tool switching, so the manufacturing cost is high; the existing injection molding technology has limited process capabilities, if it is used for direct molding with large dimensions and structural Complex products, products are easily deformed during sintering and difficult to repair
[0003] Therefore, it is necessary to provide a kind of manufacturing method of complex metal products to overcome the above technical problems

[0047] see Figure 2A to Figure 2C , is a schematic flow chart of manufacturing the metal product 100 by using the above-mentioned method for manufacturing the metal product with complex structure provided by the first embodiment of the present invention.

[0048] First, see Figure 2A , Figure 2A A schematic cross-sectional view of a plurality of workpieces 10 and carrier substrate 20 is provided. The material or process of the supporting substrate may be different from that of the workpiece. In this embodiment, the number of workpieces 10 is four, and the shape of each workpiece 10 is different.

[0049] The material of the carrying substrate 20 is different from that of the workpiece 10 , for example, the material of the carrying substrate 20 may be ceramics. When the density of the supporting substrate 20 is higher than that of the workpiece 10, the metal product 100 can be used as an appearance part.

[0050] The carrier substrate 20 may be formed by forging or forg...

[0058] see Figure 3A to Figure 3C , the second embodiment is a flow chart of a metal product 200 with an undercut shape and a complex structure prepared by using the above-mentioned injection molding technology. This metal product 200 with a complex structure also includes multiple workpieces 30 and a support member 40 . Since it is a cross-sectional view, we can only see two workpieces 30 , and the shapes of the workpieces 30 are the same. It can be understood that the number of workpieces 30 can be multiple. The metal product 200 with a complex structure in this embodiment is different from the metal product 100 with a complex structure in the first embodiment in that: in this embodiment, the metal product 200 with a complex structure is a product with an undercut shape. Due to the special structure of this product, it cannot be directly obtained by injection molding or direct lathe processing.

Abstract

The invention relates to a manufacturing method of a metal product complex in structure. The manufacturing method of the metal product complex in structure comprises the following steps that S1, mixing smelting and granulation are conducted, specifically, power and adhesion agents are provided, mixed and then uniformly smelted to form a mixture, and then the mixture passes through a granulator toform fed materials; S2, injection molding is conducted, specifically, the fed materials are heated, and then the fed materials are injected by an injection machine to a plurality of molds which form different workpieces, so that green blanks of the multiple workpieces are formed; S3, after the multiple green blanks are degreased and sintered, the multiple workpieces are obtained; S4, bearing basematerials are provided, each workpiece and the corresponding bearing base material are one of components of the metal product complex in structure, and the workpieces are combined on the bearing basematerials according to the shape structure of the metal product complex in structure, so that a preformed product is formed; and S5, welding is conducted, specifically, the preformed product is welded, and therefore the multiple workpieces and the bearing base materials can be combined, and the metal product complex in structure is obtained.

Description

technical field [0001] The invention relates to the technical field of powder injection molding, in particular to a method for manufacturing a metal product with a complex structure and the metal product with a complex structure produced by the method. Background technique [0002] For products with high precision requirements, large external dimensions, high appearance requirements and complex structures, although traditional machine tool processing methods can be achieved, what the machine tool obtains is a rough embryo, and the rough embryo to the product requires rough machining and finishing. There are too many machining allowances and waste of materials; and it takes man-hours for processing and tool switching, so the manufacturing cost is high; the existing injection molding technology has limited process capabilities, if it is used for direct molding with large dimensions and structural Complex products that are prone to deformation during sintering and are difficult...
