A Universal Fixture for Mold Electrode Processing

Abstract

The invention discloses a universal fixture of mold electrode machining. The universal fixture of the mold electrode machining comprises a standard piece clamping groove, an electrode clamping groove, a locating rib and standard chuck matching grooves. The standard piece clamping groove is formed in the bottom of the fixture, the electrode clamping groove is formed in the left side of the standard piece clamping groove, the number of the standard chuck matching grooves is two, the standard chuck matching grooves are formed in the bottom end on the inner side face of the standard piece clamping groove, and the locating rib is arranged at the bottom end of the electrode clamping groove. An electrode only needs to be clamped one time without the need for multiple times of fixture changing in the machining processes of CNC machining, electric discharge forming and wire-electrode cutting machining, not only can clamping accuracy and repeated locating accuracy of the mold electrode be improved, but also machining efficiency of mold manufacture can be improved, and the universal fixture of the mold electrode machining is beneficial to a flow line production of mold manufacturing.

Description

technical field [0001] The invention relates to the field of injection mold processing fixtures, in particular to a universal fixture for mold electrode processing. Background technique [0002] Injection mold processing includes various processing methods such as turning, milling, grinding, wire cutting and EDM. A pair of molds, especially in the processing of its cavity, often use EDM electric discharge forming processing, and when processing electrodes for EDM electric discharge forming processing, the processing machine tools used are different according to the different processing procedures. Processing on different processing machines requires the use of different fixtures to clamp and position the electrode. Each disassembly and clamping process of the fixture will not only bring a lot of tedious and repetitive mechanical labor, prolong the processing time, but also affect the mold electrode. Clamping accuracy and repeat positioning accuracy. [0003] like figure 1...

AI Technical Summary

Problems solved by technology

After the machining of the electrode is completed in the CNC machining center, if wire-cut processing is required, the wire-cut wire needs to pass through the workpiece. Due to the barrier between the clamping groove and the base of the above fixture, the wire-cut wire cannot pass through the electrode, so that the processing cannot be completed. , so that the fixture needs to be replaced again; when the processed electrode needs to be used for EDM electric discharge forming processing, the fixture must be replaced again, so the repeated positioning accuracy of the electrode is not high, the clamping error increases, and the work efficiency is reduced.
