Description
Technical field
Poured the present invention relates to a kind of device of injection mold part processing electric discharge, more particularly to one kind for cylindrical work
The electric discharge device and application method of mouth.
Background technology
The structure of a multi-cavity mold, is the more structure used of current injection mold, therefore quantity required is larger.But this form
Mould structure it is complex, be especially embodied in the cast gate of mould processing on, cast gate be melt plastics flow into mold cavity shape
Into the last critical point of product, the selection of mould gate position and the crudy of cast gate play vital to the quality of product
Effect.The traditional diamond-making technique of mould gate is：Spark-erosion machine tool is started workpiece is carried out in itself with amesdial to even up centering, then
Adjustment sine magnetic table angle makes workpiece cast gate perpendicular to spark-erosion machine tool, then perceives work(by the contact of lathe with cast gate electrode
Can, workpiece configurations are carried out to determine discharge position in four sides point.But this method be only applicable to that workpiece configurations are upright and number of packages compared with
Few mould, run into that mold cavity number is more and workpiece configurations irregular, and especially cylindrical work evens up the time in centering point
Longer and mould gate precision and outward appearance are difficult to ensure that.
The content of the invention
In view of the deficiency that prior art is present, the present invention provides a kind of electric discharge device for cylindrical work cast gate and made
With method, the present apparatus does not even up centering in itself to workpiece, and centering is evened up to the jig base for loading cylindrical work, is ensureing note

One cylindrical work is set respectively, and cylindrical work bottom is arranged in rotation stop hanging platform, to prevent cylindrical work from turning in hole
It is dynamic to cause discharge error；
Two inclined-plane reference planes I and the angle in jig base face are 40 degree, two inclined-plane reference planes II and the angle in jig base face
Spend for 50 degree.
A kind of electric discharge device application method for cylindrical work cast gate, it is characterised in that：Step is as follows,
The electric discharge device of cylindrical work is first will be equipped with, is placed on the sine magnetic table of spark-erosion machine tool, with amesdial to tool bottom
Seat profile evens up centering, then adjusts sine magnetic table angle, makes cylindrical work cast gate angle vertical in spark-erosion machine tool, will pour
Mouthful electrode clamping starts spark-erosion machine tool, obtained just with the contact perceptional function of spark-erosion machine tool on spark-erosion machine tool
True Working position, you can connect respectively with inclined-plane reference plane I, inclined-plane reference plane II with the head directly using cast gate electrode
Sense of touch knows realization positioning, because the angle in inclined-plane reference plane I and jig base face is 40 degree, thus with cast gate angle 40 degree be flat
Row relation, the available relative position A sizes with cast gate of cast gate electrode head touching inclined-plane reference plane I；Due to inclined-plane reference plane
II is 50 degree with the angle in jig base face, thus with cast gate angle 40 degree be vertical relation, such cast gate electrode head is touched
The available relative position B sizes with cast gate of inclined-plane reference plane II, such cast gate electrode need not be answered cylindrical work again
Miscellaneous centering seeks side, you can the accurate electric discharge of multi-cavity cylindrical work cast gate is realized by simple and efficient mode.
The beneficial effects of the invention are as follows：The device is ingenious in design, working stability, and compact conformation is easy to process, each portion of device
Divide part formation standardization, it is easy to change.Conventional method can only be by electrode and workpiece for the centering of evening up of cylindrical work
The point way of contact, contact area is small, and to cause workpiece to even up the unproductive times such as centering longer:Single-piece unproductive time is 10 minutes left sides
The right side, electric discharge precision is relatively low:Generally 0.03 to 0.05mm.The present apparatus does not even up centering in itself to workpiece, to loading cylindrical work
The jig base of part evens up centering, because the relative position in counterbore of the workpiece in jig base is fixed, once evens up centering
Can be discharged 6 workpiece, and unproductive time is 3 minutes, and the unproductive time of average each workpiece is only 0.5 minute, and 6 workpiece can be saved
Nearly 1 hour unproductive time；The way of contact of cast gate electrode pair jig base both sides inclined-plane reference plane connects for face in the technical program
The mode of touching, the positioning precision to workpiece is high, and electric discharge precision is general within 0.01mm, realizes the electric discharge of cylindrical work cast gate
Uniformity, while improving processing efficiency.
