Abstract
The invention relates to a fixing device for a sprue electrode. The fixing device comprises a base, a large spring clamp, a connecting rod and a small spring clamp, wherein the upper part of the base is provided with screw threads; the large spring clamp for clamping the connecting rod is screwed into and fixedly arranged at the upper part of the base; the upper part of the connecting rod is provided with screw threads; and the small spring clamp is screwed into and fixedly arranged at the upper part of the connecting rod. The device is artful in design, stable in working, compact in structure and convenient to machine; and the clamping forces of the spring clamps are uniform, and one-step precise location is realized during processing, so that the perpendicularity of a processed sprue reaches up to 0.01mm, meanwhile, the consistency of sprues of multi-cavity moulds is ensured, the rejection rate is reduced, the mould processing efficiency is increased, and the fluctuation of a personnel operating skill to the mould processing quality is stopped.
Description
Technical field
The present invention relates to the device of a kind of injection mould processing, particularly relate to a kind of stationary installation 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 demand quantity is bigger. But the mould structure of this form is comparatively complicated, especially it is embodied in the cast gate processing of mould, cast gate is the last critical point that the plastics melted flow into that mold cavity forms product, it suffices to say that the quality of product is played a part most important by the selection of mould gate position and the processing quality of cast gate. The traditional diamond-making technique of mould gate is the direct processing mold steel plate of cast gate electrode utilizing spark-erosion machine tool fixture fixing, but this kind of method owing to fixture adopts direct clamping sides fix, and clamp angle and the consistence that dynamics, the degree of depth and precision are all difficult to ensure that cast gate electrode enters mould steel plate, even if can evening up to look for and just ensureing entry angle, also process period must be extended, and the structure of a multi-cavity mold is also difficult to ensure the consistence of card multi-cavity. And also bring the fluctuation of cast gate quality due to the experience level of employee's operation, and then cause the fluctuation of quality product.
Summary of the invention
In view of the deficiency that prior art exists, the object of the invention is that providing a kind of is ensureing under injection-moulded plastic part product appearance, dimensional precision and the prerequisite of die life, the stationary installation that high level, high-level efficiency are used for the cast gate electrode of multi-cavity mold complete cast gate quick, accurately process.
For achieving the above object, the present invention adopts following technical scheme: a kind of stationary installation for cast gate electrode, it is characterized in that: comprise base, big spring folder, union lever, little spring pinchcock, described base top is provided with screw thread, described union lever top is provided with screw thread, the described big spring folder screw-in being clamped with union lever is fixed on base top, and described little spring pinchcock screws in and is fixed on union lever top.
This apparatus design is ingenious, working stability, compact construction, easy to process, owing to spring pinchcock clamping dynamics is even and the course of processing is once accurately located, ensure that processing cast gate verticality reaches 0.01mm, ensure that the consistence of multi-cavity mold cast gate simultaneously, reduce condemnation factor, it is to increase Mould Machining efficiency, stop human users's technical ability to the fluctuation of Mould Machining quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the working state schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in the figure, a kind of stationary installation for cast gate electrode, it comprises base 1, big spring folder 2, union lever 3, little spring pinchcock 4, base 1 top is provided with screw thread, big spring folder 2 screw-in being clamped with union lever 3 is fixed on base 1 top, union lever 3 top is provided with screw thread, and little spring pinchcock 4 screws in and is fixed on union lever 3 top.
During work, cast gate electrode 5 is clamped in little spring pinchcock 4 and fixes, whole device is placed in spark-erosion machine tool top securing bolt locking base 1, starts lathe, process the mould steel plate being 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 unclamp and continue processing after cast gate electrode 5 changed by little spring pinchcock 4, ensure once to look for positive post-treatment. So namely, the precision sizing of mould gate is realized by simple and efficient mode.
