Abstract
The utility model relates to a fixing device for runner electrode. It includes that base, big spring clamp, connecting rod, little spring press from both sides, and base upper portion is equipped with the screw thread, and the centre gripping has the big spring clamp screw in of connecting rod to fix on base upper portion, and connecting rod upper portion is equipped with the screw thread, and the little spring presss from both sides the screw in to be fixed on connecting rod upper portion. The device design benefit, job stabilization, compact structure, processing is convenient, because spring clamp clamping -force degree is even and an accurate positioning of course of working, guarantees that the processing runner hangs down straightness and reaches 0.01mm, has guaranteed multicavity mold gate's uniformity simultaneously, has reduced the disability rate, improves mould machining efficiency, has stopped the fluctuation of personnel's operative skill to mould processingquality.
Description
Technical field
This utility model relates to the device of a kind of injection mould processing, particularly relates to a kind of fixing device for cast gate electrode.
Background technology
The structure of a multi-cavity mold is the structure of the more use of current injection mold, and therefore quantity required is bigger.But the mould structure of this form is complex, especially it is embodied in the cast gate processing of mould, cast gate is the last critical point that the plastics melted flow into mold cavity formation product, it may be said that the selection of mould gate position and the crudy of cast gate play vital effect to the quality of product.The traditional diamond-making technique of mould gate is the cast gate electrode direct processing mold steel plate utilizing spark-erosion machine tool fixture fixing, but this method uses direct clamping sides to fix due to fixture, and clamp dynamics, the degree of depth and precision and be all difficult to ensure that cast gate electrode enters angle and the concordance of mould steel plate, even if centering can be evened up ensure entry angle, also must extend process time, and the structure of a multi-cavity mold is also difficult to ensure the concordance of card multi-cavity.And owing to the experience level of employee's operation also brings the fluctuation of cast gate quality, and then cause the fluctuation of product quality.
Summary of the invention
The deficiency existed in view of prior art, this utility model purpose is to provide a kind of and is ensureing injection-moulded plastic part product appearance, dimensional accuracy and on the premise of die life, high level, high efficiency for the fixing device of the cast gate electrode of multi-cavity mold complete cast gate quick, accurately process.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that a kind of fixing device for cast gate electrode, it is characterized in that: include that base, big spring folder, connecting rod, little spring press from both sides, described base top is provided with screw thread, described connecting rod top is provided with screw thread, the described big spring folder screw-in being clamped with connecting rod is fixed on base top, and described little spring folder screw-in is fixed on connecting rod top.
The design of this device is ingenious, working stability, compact conformation, easy to process, due to alligator clamp clamping dynamics, uniformly and the course of processing is once accurately positioned, it is ensured that machining pouring gate perpendicularity reaches 0.01mm, ensure that the concordance of multi-cavity mold cast gate simultaneously, reduce scrappage, improve mould working (machining) efficiency, stopped the fluctuation to mould crudy of human users's technical ability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is working state schematic representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in the figure, a kind of fixing device for cast gate electrode, it includes base 1, big spring folder 2, connecting rod 3, little spring folder 4, base 1 top is provided with screw thread, big spring folder 2 screw-in being clamped with connecting rod 3 is fixed on base 1 top, connecting rod 3 top is provided with screw thread, and little spring folder 4 screw-in is fixed on connecting rod 3 top.
During work, cast gate electrode 5 is clamped in little spring folder 4 and fixes, whole device is placed in spark-erosion machine tool top clamping screw locking base 1, starts lathe, the mould steel plate that processing is placed in lathe lower platform, each chamber of processing mold one by one.If needing to change cast gate electrode 5, it is only necessary to continue processing after unclamping little spring folder 4 replacing cast gate electrode 5, it is ensured that a centering post-treatment.So can realize the Precision Machining of mould gate by the way of simple and efficient.
