Abstract

The invention relates to the technical field of mold machining and manufacturing, in particular to a vibration reduction type electrode tool for mold machining and a vibration reduction method. The vibration reduction type electrode tool comprises a base used for being connected with a main shaft of an electric spark machine tool, a pipe body vertically arranged in the middle of the base, a threaded choke plug connected to the cantilever end of the pipe body in a threaded fit mode, and a threaded connecting column arranged at the front end of the threaded choke plug and used for installing an electrode. The pipe body axial stretching damping device is arranged in the pipe body and comprises a threaded ejector pin and an axial ejector rod, the threaded ejector pin is arranged in the center of the base, and the axial ejector rod is arranged in the pipe body, located between the threaded choke plug and the threaded ejector pin and used for applying axial stretching pre-tightening force to the pipe body. Vibration of the slender electrode tool can be reduced, the machining quality of the mold cavity face is improved, and electrode abrasion is reduced.

Description

technical field [0001] The invention relates to the technical field of mold processing and manufacturing, in particular to a vibration-damping electrode tooling for mold processing and a vibration-damping method. Background technique [0002] Injection mold is a kind of mold used to produce plastic products. Because some plastic products have complex shapes, the cavity of the mold is also relatively complicated, and the processing of the cavity is also difficult. It is often necessary to use special electrode tooling for Complex cavities are processed by CNC EDM. [0003] However, when the cavity depth of the mold is deep, it is necessary to use the electrode tooling with a long rod body, which may cause vibration of the electrode tooling rod body in CNC EDM, which on the one hand leads to a large processing quality of the mold cavity surface The amplitude decreases, on the other hand, it will also cause accelerated wear of the electrode. [0004] Therefore, it is necessar...
