Description

[0001] The present invention relates to a discharge electrode jig device,

More particularly, the present invention relates to a CNC machined discharge electrode jig device, and more particularly, to a CNC machined discharge electrode jig device, in which a plurality of discharge electrodes (workpieces) And a plurality of discharge electrodes can be machined simultaneously at the same time.

In general, precision molds such as mobile phone molds are composed of a plurality of ribs, which are very compact in shape and design, and have strength reinforcement and functionality. Therefore, as a finishing means for minimizing the tolerance range of such precision molds, Thereby improving the accuracy.

Since electrodes of various kinds and sizes are required to perform discharge machining by means of finishing processing of a precision metal mold, electrodes to be machined are inserted into a jig for fixing the discharge electrode, fixed with a fastening member, Shape and thickness. In addition, discharge machining refers to a method of processing a target object into a specific shape by utilizing the physical and mechanical action that occurs when a discharge occurs between two electrodes.

Patent Application No. 10-2006-130555 and No. 10-2008-35798 disclose that a conventional plate-shaped discharge electrode has a pattern surface of a shape to be processed, and the discharge electrode has a concavo-convex portion protruding from a surface opposite to the pattern surface And is engaged with the holder by tightening with bolts in a state of being fitted to the concave-convex portion of the holder. The discharge electrode has a concavo-convex portion formed over the entire length for engagement with the fixed holder. Korean Utility Model No. 20-0378452 proposes a discharge electrode of a type in which a corrugated portion is processed in advance to reduce the cost. The cutting process in the shape of the concave / convex portion can reduce the cost of the lost portion, and the concave / convex portion remains as it is and is still subject to improvement. When copper is used as the material of the discharge electrode, the existence of the concave / convex portion becomes a large burden. When graphite is used as the material of the discharge electrode, the burden is further increased. In addition, in connecting the discharge electrode to the fixed holder, the center of the irregular portion must be exactly in the longitudinal direction in relation to the fixed holder, and the width of the discharge electrode is fixed to the fixed holder . Therefore, replacing a large number of discharge electrodes in a large automation facility requires considerable time and cost.
