Embodiment

[0041] refer to figure 1 with figure 2 , a bone slice electrode, comprising: a base 11 and four electrode teeth 12 on the top surface of the base 11 .

[0042] The four electrode teeth 12 are distributed in a "cross" shape and arranged at intervals. The length extension direction of the electrode teeth 12 is perpendicular to the ring shape, and the length extension direction of the opposite electrode teeth 12 is consistent. The setting position and quantity of the electrode teeth 12 are adapted to the bone position to be processed on the mold. After the power is turned on, the electrode teeth 12 realize the precise machining of the bone position of the mold through discharge corrosion, ensuring the shape and accuracy of the glue position on the mold, thereby reducing the mold bone. bit processing difficulty.

[0043] The electrode tooth 12 is a structure with a thin top and a thick bottom, and the inclination angle of its side wall is 0.2-0.8°. It is preferable that the inc...

Abstract

The invention discloses a bone position thin slice electrode and a machining method thereof, and belongs to the technical field of electrodes. The bone position slice electrode comprises a base and four electrode teeth located on the top face of the base, wherein the four electrode teeth are distributed in a cross shape and are arranged at intervals. By arranging the bone position thin slice electrode with the structure, the machining difficulty of mold bone positions is reduced through electrode discharge corrosion in the mold bone position machining process, and the shape and precision of gluing positions on a mold are ensured; and the number of the electrode teeth is matched with the number of the bone positions of the mold, so that the problem that the bone positions in a limited area are difficult to machine is further solved.

Description

technical field [0001] The invention relates to the technical field of electrodes, in particular to a bone slice electrode and a processing method thereof. Background technique [0002] In the process of precision plastic mold design, due to the strict requirements on the position and wall thickness of the mold product, the special bone position of the product part in the mold structure has to be designed to be very thin and deep, which eventually makes some glue positions thin and high. , often the ratio of height (H) to thickness (W) can reach 20 to 30 times. Such a structural design is not easy to demould, so it requires high surface finish and good verticality to ensure the fluidity of the glue and the accuracy of the product position. [0003] Even if the precision conditions of the mold can be met by EDM by manufacturing specific bone electrodes, there are still difficulties in the manufacturing and processing of the electrodes, and the electrodes cannot be bent and d...
