22 U-shaped structure.The frame portion 23 is U-shaped structure setting, corresponds to a part of the frame of center, in subsequent assembling
In, it can be docked with the frame in other middle-frame mould groups.
S22: carrying out CNC processing to the front of mental section 10, as shown in figure 5, the friendship in middle plate portion 22 and frame portion 23
The second injection structure 25 of the first injection structure 24 of connection is formed at boundary.
It is a module of center as corresponding to middle-frame mould group, so when CNC processes mental section 10, for this
Frame portion 23 included in middle-frame mould group, which divides to divide with middle plate portion 22, is cut, and is subsequent injection molding pre-production
Corresponding first injection structure 24 and the second injection structure 25.Meanwhile first injection structure 24 be set to the anti-of mental section 10
Face, the second injection structure 25 are set to the front of mental section 10 and are connected to the first injection structure 24, can be in injection molding
Obtain the plastic parts 26 being embedded between the front and back sides of mental section 10.
S30: being molded to mold plastic parts 26 on blank 20, which is located at middle plate portion 22 and frame
Between portion 23.
For example, as shown in fig. 6, molding plastic parts 26 on blank 20, the plastic parts by the way of nanometer injection molding
26 take shape on the first injection structure 24 and the second injection structure 25, and are embedded between the front and back sides of blank 20.Nanometer
Injection molding (full name in English: Nano Molding Technology, abbreviation are as follows: NMT), is a kind of metal and plastics with nanometer
Metal surface is first carried out nanosizing processing, then directly exports plastics and be molded over metal surface by the technique that technology combines,
Metal can be integrally formed with plastics, metal appearance texture can not only be taken into account, and can simplify the design of product structure part,
So that product is more lightening.
S40: CNC processing is carried out to obtain molding middle-frame mould group 100 to blank 20.
As shown in Fig. 7 to Figure 13, above-mentioned S40 can with comprising steps of
S41: CNC processing is carried out to correct the shape of plastic parts 26 to plastic parts 26.
S42: centering plate portion 22 carries out CNC processing to obtain preset middle plate.
S43: CNC processing is carried out to obtain preset frame to frame portion 23.
S44: the middle-frame mould group 100 comprising plastic parts 26, middle plate and frame is obtained.
After moulding, it needs respectively to finish plastic parts 26, middle plate portion 22 and frame portion 23 respectively,
To correct the shape of each section on blank 20, it is allowed to more match the shape of preset middle-frame mould group.
It should be noted that there is no strict sequences, for wherein for above-mentioned S41, S42 and S43
Certain two step perhaps three steps can be synchronous in a CNC processing or be staggeredly carried out.
For example, as shown in fig. 7, carry out roughing to the outside of frame portion 23 to form the region of indent, meanwhile, to blank
