It should be noted that, the degree of depth of standard station is touched several for the datum plane for positioning action herein; The product face of electrode body is for adding the discharge face relative with Mould Machining surface in man-hour.Wherein, when the electric discharging machining electrode by the present embodiment carries out a plurality of feature machining on mould, need to control standard station motion, for example rotation or skew, thereby utilize its combined electrode body and two identical electrode bodies of structure to process, improve the commonality of electric discharging machining electrode.
Wherein, in order better to improve the commonality of electric discharging machining electrode in this enforcement, can be as shown in Figure 2, the electrode body 23 touching on several 22 in a degree of depth of standard station 21 comprises coplanar, spaced the first plates 231 and the second plates 232, and the first plates 231 and the second plates 232 are combined electrode body, and the first plates 231 product face development lengths are greater than the second plates 232 product face development lengths, can, according to the needs of reality processing, select the first plates 231 or the second plates 232 to process thus.
Need clearly, the structure of electrode body 23 can be for multiple, such as column, bar paten structure etc.
Particularly, as shown in Figure 2, in the first plates 231, the height value of height major part equates with the height value of height major part in the second plates 232, and be preferably 13 millimeters, in corresponding the first plates 231, the height value of height smaller portions equates with the height value of height smaller portions in the second plates 232, and is 10-12 millimeter.Preferably, when the first plates 231 and the second plates 232 are directly fixed on standard station 21, because electrode body 23 is plates structure, therefore in order to improve fixing stability, can set up connecting portion 211, connecting portion 211 can be rectangular structure, and the degree of depth that is fixed on standard station 21 touches on several 22, then by the first plates 231 and the second plates 232 are fixed on connecting portion 211.This wherein, connecting portion 211 can be selected material or the structure good with electrode body 23 connectivities.
