Die sprue machining jig

Abstract

The invention discloses a die sprue machining jig which comprises a benchmark piece, a sine table fixed to the benchmark piece, an electrode clamping block installed on the sine table through a rotating shaft, a block gauge, a supporting pillar and an oil flushing pipe, wherein the block gauge and the supporting pillar are arranged at the positions, corresponding to the electrode clamping block, on the sine table, and an electrode is fixedly clamped in the electrode clamping block. A clamping groove is formed in the upper side face of the block gauge, the supporting pillar is arranged in the clamping groove and supports the electrode clamping block from the lower side face of the electrode clamping block so that a fixed machining angle can be formed by the electrode, and a locking screw isused for locking the sine table with the fixed angle so that a rotating shaft can be fixed and locked; and an oil spraying opening of the oil flushing pipe is aligned with a machining slope of the electrode for conducting high-speed oil spraying. By means of the die sprue machining jig, 0-90 degree accurate machining of a sprue is achieved according to design requirements of a die, and the purpose of fast slag discharging is achieved; and meanwhile, the center of an electrode obtained after replacing can be maintained unchanged, and the machining efficiency and precision are greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection moulds, in particular to a mould gate processing fixture. Background technique [0002] According to the actual production needs, when processing the gate of the injection mold through EDM, the processing angle of the existing processing method is fixed, and there are only several electrode processing methods of 30°, 45° and 60°, and the existing method cannot align the electrode. Oil flushing on the inclined plane makes it difficult to discharge slag, cannot meet the needs of multi-angle processing, and the processing efficiency is low. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a mold gate processing jig, which includes a reference piece, a sine stage fixed on the reference piece, and an electrode clamp block mounted on the sine stage through a rotating shaft, corresponding to the The electrode clamp block is arranged on ...
