Embodiment
The utility model is described in detail illustrated embodiment below in conjunction with the accompanying drawings.
A kind of cold stamping shaped group Mold Making process of spelling of body outer skin is：
A, division forming surface, are divided into four to eight cellular zones by shaping entirety, die unit body matrix number are prepared according to twice of cellular zone number；
B, the machine-shaping face on single die unit body, assemble the mould molding part being made up of die unit body；
C, manufacture backing plate at bottom, positioning baffle, positioning hole and alignment pin；
D, respectively assembling punch-pin and cavity plate, matched moulds are simultaneously corrected.
In step a, die unit body matrix number is twice of division unit area number, is respectively used to punch-pin shaping and cavity plate shaping.
In step b, machine-shaping face is processed on each die unit body matrix respectively, and the moulding section of mould is that forming surface on each die unit body is spliced and combined and formed.
Example 1. manufactures and designs a kind of cladding element punch mould as shown in Figure 2.
The first step, divides forming surface, and the covering according to Fig. 2 is divided into six formation of lots cellular zones with three space planes.As a result as shown in figure 3, wherein A faces, B faces and C faces are parallel to each other perpendicular to covering horizontal plane, and the plane of B, C two, spacing.
Second step, manufactures die unit body, and its method is：Choose that size is suitable and the 5CrNiMo Jing Guo modifier treatment, vice, which is clamped on grinding machine, grinds a basal plane, this basal plane as cell cube bottom surface.Afterwards turn over any one face of 90 ° of mills and plane perpendicular.Then, milled out with milling cutter on four faces vertical with basal plane and be connected boss and link slot.It is last to make forming surface in top surface Digit Control Machine Tool or with milling cutter.The punch member body produced is as shown in Figure 4.Six module unit bodies are assembled into punch-pin moulding section, the moulding section 2 that die unit body as shown in Figure 5 is constituted.Cavity plate cell cube is manufactured in the same way, assembles cavity plate moulding section.
3rd step, according to the big little makings of second step mould surface backing plate at bottom 1 as shown in Figure 5, positioning baffle 3, positioning hole 4 and alignment pin 5.
