Description
Technical field
The utility model relates to rubber mold Electric Discharge Machining technical field, relates in particular to a kind of electrode tool that is used for the rubber mold Electric Discharge Machining.
Background technology
Spark machined is carried out in liquid medium, the auto-feed adjusting device of lathe makes the suitable discharging gap of maintenance between workpiece and the tool-electrode, when applying very strong pulse voltage (reaching the breakdown voltage of gap medium) between tool-electrode and the workpiece, can puncture medium dielectric strength lowest part, because region of discharge is very little, discharge time is extremely short, so energy height is concentrated, make the temperature of region of discharge instantaneous, the metal local melting on surface of the work and tool-electrode surface even vaporization evaporation up to 10000 ℃-12000 ℃.The metal of local melting and vaporization is thrown in the working solution under the effect of explosive force, and is cooled to small metal particles, is dashed from the workspace rapidly by working solution then, thereby makes surface of the work form a small pit; Once after the discharge, the dielectric strength of medium recovers to wait for discharge next time, makes surface of the work constantly by ablation so repeatedly, and copy the shape of tool-electrode on workpiece, thereby reach the purpose of processing and forming.Spark machined is the important method of making when front mold, and especially in injection mold was made, spark machined was a kind of irreplaceable process; Spark machined at first is installed on workpiece workbench and workpiece is proofreaied and correct, and thereafter electrode is installed on the machine tool chief axis, makes the electrode axis consistent with the main-shaft axis direction, and the assurance electrode is processed under vertical situation with workpiece.But complicated along with mold shape, and variation, the mould form interior shape becomes inconsistent back-off shape with product depanning direction.Present domestic mold manufacturing industry is used the most general in reality processing, method generally is that workpiece is ajusted corresponding angle with sinusoidal magnetic platform the most widely, utilizing electrode to do the vertical servo processing of Z axle finishes, its maximum drawback is that workpiece size is big, put very difficulty of angle, electrode and workpiece are decided to be precision and are difficult to control, the fixing difficulty of workpiece, accident appears in handling ease, and can't realize the full-automatic unmanned processing in many types of chamber.
The utility model content
At above defective, the purpose of this utility model provides a kind of electrode tool that is used for the rubber mold Electric Discharge Machining, to guarantee clamping simplification, easily correction, dimensional accuracy height, the process safety of large-size workpiece.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electrode tool that is used for the rubber mold Electric Discharge Machining, comprise electrode top guide and processing die head, the tool-electrode upper end is provided with the electrode top guide and is installed on the electric spark machine tool main shaft, the bottom of electrode top guide connects the discharge card, described discharge card downside is provided with the processing die head of evagination, and the vertical plane of these processing die head both sides and horizontal plane are offered vertical processing datum and horizontal processing datum respectively.
The beneficial effect that is used for the electrode tool of rubber mold Electric Discharge Machining described in the utility model is: to clamping simplification, easily correction, dimensional accuracy height, the process safety of large-size workpiece, can realize many types of chamber, long-time, operatorless full-automatic processing, the time that significantly reduced clamping in the edm process, repeats to adjust, can finish whole process more stable, faster, thereby improved spark machined efficient, shorten die manufacturing cycle, more effectively promoted Enterprises'Competitiveness.
