Problems solved by technology
[0002] At present, the middle frame brackets of many mobile electronic equipment metal casings are made of pure aluminum profiles or stainless steel plates, and the basic frame structure is formed by CNC milling machine processing. For the CNC milling process section, a complete profile is used However, direct molding after multiple processes requires very high precision of processing equipment, and also has defects such as long processing cycle, large waste of raw materials, high defect rate and high processing cost.

Embodiment Construction
[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0034] A production process of a middle frame structure, comprising the following steps:
[0035] Step 1. Forming frame 1 and middle plate 2. The formed frame 1 includes a plurality of segmented frames 3 that are not connected to each other, such as figure 2 As shown, the middle plate 2 is formed by a die-casting process, and its formed structure is as follows image 3 shown;
[0036] Step 2, the first machining: machining the structure on the frame 1, including forming the external device interface, the button hole 6 on the frame 1 or fine milling the frame 1, the external device interface can be the earphone hole 4, the USB hole 5, Such as Figure 4 shown;
[0037] Step 3: Perform insert injection molding on the middle plate 2 to form an injection molded plastic structure 7, such as Figure ...

The invention discloses a middle frame structure manufacturing technology and relates to the technical field of mobile electronic equipment. The manufacturing technology comprises the following steps: step I, forming an edge frame and a middle plate; step II, performing first machining of processing a structure on the edge frame; step III, performing insert injection molding of the middle plate to form an injection molding plastic structure; step IV, assembling and fixing the edge frame subjected to first machining and the middle plate formed by insert injection molding so as to form a middle frame structure; step V, performing second machine of conducting finish milling the outer surface of the middle frame to form a corresponding structure on a middle frame; and step VI, performing after-treatment to form a final finished product of the middle frame structure. The sequencing of the step II and the step III is not limited. The invention also discloses a middle frame structure processed by the abovementioned manufacturing technology. The middle frame structure manufacturing technology and the middle structure provided by the invention overcome disadvantages that a middle frame structure processing technology is complex and the production cost is high in the prior art.
Description
technical field [0001] The invention relates to the technical field of mobile electronic equipment components, in particular to a production process of a middle frame structure and the middle frame structure. Background technique [0002] At present, the middle frame brackets of many mobile electronic equipment metal casings are made of pure aluminum profiles or stainless steel plates, and the basic frame structure is formed by CNC milling machine processing. For the CNC milling process section, a complete profile is used However, direct molding after multiple processes requires very high precision of processing equipment, and also has defects such as long processing cycle, large waste of raw materials, high defect rate, and high processing cost. With the development of metal technology and consumers' demand for innovative products, it is urgent to develop new production processes to make products with low production cost and high strength to meet the needs of consumers.
