Step 3: form lines at the circular-arc machined surface of said mold cavity through the said second electrodes use spark machine.
Preferably; In order to confirm the depth of said second electrode accurately at the lines of the machined surface processing of said mold cavity; Between step 2 and step 3; Also comprise steps A 1: the surfaces coated at the circular arc of said mold cavity is joined the red lead that mould is used, and second electrode gently is pressed on the machined surface of said mold cavity, and the density depth adjustment lathe of the lines that is impressed according to the above second electrode of red lead changes its depth at the lines of said mold cavity machined surface processing.
In order further to confirm the depth of said second electrode at the lines of the machined surface processing of said mold cavity; Behind step 3 A1; Also comprise steps A 2: paper more smaller of pad on the circular arc of the machined surface of said mold cavity than the area of said mold cavity, with said second electrode platen gently, according to the depth that the impresses processing dynamics of the said machined surface of said second electrode pair of accurate adjustment once more; And a piece of paper is once changed in every adjustment, and the impression on paper distributes more even.
Preferably, damage in the process of processing for fear of said second electrode, the material of said second electrode is softer red metal.
Preferably, in step 1, adopt said first electrode of machined into and said second electrode, and the lathe that is used to process said second electrode is speed lathe, the rotating speed when it processes said second electrode is 600 revolutions per seconds.
Preferably, the spark machine that in step 1 and step 2, is adopted is the high speed spark machine.
Preferably, said lines is shaped as zigzag.
The processing method of automotive wheel cover mold tool die cavity of the present invention compared with prior art has following beneficial effect:
The processing method of automotive wheel cover mold tool die cavity of the present invention can be processed has thin and close high-quality mold cavity, and long through this method processed mould life-span, satisfies the big requirement of mould demand of the big product of output.
Description of drawings
Fig. 1 is first electrode of the processing method of automotive wheel cover mold tool die cavity of the present invention and the processing sketch map of mold cavity;
Fig. 2 is second electrode of the processing method of automotive wheel cover mold tool die cavity of the present invention and the processing sketch map of mold cavity.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
Like Fig. 1 and shown in Figure 2, the processing method of a kind of automotive wheel cover mold of the present invention tool die cavity, it comprises:
Step 1: make and to have first electrode 1 of cambered surface, and make cambered surface be positioned at the front end of said first electrode 1, and make and have second electrode 2 of lines, and make lines be positioned at the front end of said second electrode 2;
Step 2: adopt spark machine to make the machined surface 31 of mold cavity 3 be processed as circular arc through said first electrode 1;
Step 3: adopt spark machine to form lines at the circular-arc machined surface 31 of said mold cavity 3 through said second electrode 2.
Preferably; In order to confirm the depth of the lines that said second electrode 2 is processed to form at the machined surface 31 of said mold cavity 3 accurately; Between said step 2 and said step 3; Also comprise steps A 1: the surfaces coated at the circular arc of said mold cavity 3 is joined the red lead that mould is used; Said second electrode 2 gently is pressed on the machined surface of said mold cavity 3, and the density depth adjustment lathe of the lines that is impressed according to the above second electrode 3 of red lead changes its depth at the lines of said mold cavity 3 machined surfaces 31 processing.At this, the applied red lead of this preferred embodiment also can adopt other can produce other material of impression, also can reach the object of the invention.
In order further to confirm the depth of said second electrode 2 at the lines of machined surface 31 processing of said mold cavity 3; After steps A 1; Also comprise steps A 2: paper more smaller of pad on the circular arc of the machined surface 31 of said mold cavity 3 than the area of said mold cavity 3; With this paper of said second electrode 2 pressure gently; According to the depth processing dynamics of the said machined surface of said second electrode pair of accurate adjustment once more of impression, and every adjustment once changes a piece of paper, and the impression on paper distributes more even.In the present embodiment, applied here paper is preferably the blank sheet of paper of thinner thickness, is convenient to observe the impression that is pressed on the paper.
