Problems solved by technology

[0003] The middle frame is an indispensable part of 3C products, its appearance is smooth, and the inner structure is relatively complicated
The outer frame of the middle frame is often set on the outside of the product, so as to protect the electronic product from damage. In the prior art, the outer frame of the middle frame is made of pure aluminum profile or stainless steel plate, which is directly processed by a CNC milling machine. In the processing stage, it is necessary to carry out multiple processes on a plate, which not only requires high precision of processing equipment, but also has disadvantages such as long processing cycle, serious waste of raw materials and high scrap rate.
The middle frame produced by this process also has the disadvantages of high processing cost, poor integrity and low strength.
With the continuous improvement of environmental protection awareness and high efficiency awareness, the existing middle frame processing technology can no longer meet the needs of production. It is urgent to develop a new technology with simple processing technology, strong integrity, low cost and short cycle, so as to produce products that meet customer needs. middle frame

Embodiment 1

[0047] Such as figure 1 Shown is a flow chart of a method for manufacturing a middle frame, and the method includes the following steps:

[0048] Step 1: Select metal profiles. Stainless steel is preferred for metal profiles. Stainless steel has corrosion resistance and is not easily corroded by air, steam or water. In addition to corrosion resistance, stainless steel also has high temperature and low temperature resistance. Such as figure 2 As shown, a plurality of side frames 101 and a plurality of bottom frames 102 formed by stamping metal profiles are spliced ​​into an outer frame 1. In this embodiment, the number of side frames 101 is four, and the number of bottom frames 102 is four. The four bottom frames 102 are spliced ​​to form the bottom edge of the outer frame 1, the bottom edge of the outer frame 1 is U-shaped, and the outer frame 1 spliced ​​by the four bottom frames 102 and the four side frames 101 is generally rectangular; Figure 6 As shown, the side frame ...

Embodiment 2

[0057] Such as Figure 2-11 The middle frame structure manufactured by the above middle frame manufacturing method is shown, and the middle frame structure includes:

[0058] The outer frame 1 is spliced ​​by a plurality of bottom frames 102 and a plurality of side frames 101. In this embodiment, the number of side frames 101 is four, the number of bottom frames 102 is four, and the number of four bottom frames The bottom edge of the outer frame 1 is spliced ​​by the frame 102, and the bottom edge of the outer frame 1 is U-shaped, and the outer frame 1 spliced ​​by the four bottom frames 102 and the four side frames 101 is generally rectangular; as Figure 6 As shown, the side frame 101 is in the shape of a line as a whole, and it includes a third bottom plate 1011 and two third vertical plates 1012. The third bottom plate 1011 is vertically provided with two third vertical plates 1012, and the two third vertical plates 1012 Parallel to each other and the length extension dir...

Abstract

The invention discloses a middle frame manufacturing method and a middle frame structure and belongs to the technical field of 3C small household electrical appliances. The middle frame manufacturing method provided by the invention comprises the following steps: after splicing a plurality of bottom borders and a plurality of side borders, which are manufactured by punching metal profiles, into an outer border and conducting pressure casting on a metal plate to manufacture a middle plate, fixing the middle plate in a die cavity, carrying out primary injection molding to form a plastic part, then conducting glue binding on the outer border, the middle plate and the plastic part to form the middle frame structure, and finally carrying out secondary injection molding and surface treatment on the middle frame structure. As for the method, by adopting a metal plate pressure casting and injection molding technology, processing steps are simplified, the processing difficulty is lowered, the processing time is saved, the utilization ratio of raw materials is also increased, and thus the processing cost is lowered. The middle frame structure processed and formed by the method has attractive, fashionable, high-end and elegant appearance and has the advantages of simple structure, strong integrality, low cost, good heat dissipation performance, high whole strength and the like.

Description

technical field [0001] The invention relates to the technical field of 3C small household appliances, in particular to a middle frame manufacturing method and a middle frame structure. Background technique [0002] 3C small home appliances usually refer to small 3C products. 3C products refer to products that combine computers, communications and consumer electronics, including computers, tablets, mobile Telephones, digital cameras, televisions, walkmans, electronic dictionaries, audio-visual hardware devices or digital audio players, etc. [0003] The middle frame is an indispensable part of 3C products. It has a smooth appearance and a complicated inner structure. The outer frame of the middle frame is often set on the outside of the product, so as to protect the electronic product from damage. In the prior art, the outer frame of the middle frame is made of pure aluminum profile or stainless steel plate, which is directly processed by a CNC milling machine. The processi...
