Fixing device for sprue electrode

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 [0001] The invention relates to a device for processing injection molds, in particular to a fixing device for gate electrodes. Background technique [0002] The structure of one mold and multiple cavities is currently the most used structure of injection molds, so the demand is large. However, the mold structure of this form is relatively complicated, especially in the processing of the gate of the mold. The gate is the final gate for the molten plastic to flow into the mold cavity to form a product. It can be said that the selection of the position of the mold gate and the processing quality of the gate have a great impact on The quality of the product plays a vital role. The traditional processing method of the mold gate is to directly process the mold steel plate with the gate electrode fixed by the fixture on the EDM machine tool, but this method is difficult to guarantee the gate due to the clamping force, depth and accuracy of the fixture because the f...

However, the mold structure of this form is relatively complicated, especially in the processing of the gate of the mold. The gate is the final gate for the molten plastic to flow into the mold cavity to form a product. It can be said that the selection of the position of the mold gate and the processing quality of the gate have a great impact on The quality of the product plays a vital role

The traditional processing method of the mold gate is to use the gate electrode fixed by the electric discharge machine tool to directly process the mold steel plate, but in this method, because the clamp is directly clamped and fixed by the side, it is difficult to ensure the clamping force, depth and accuracy of the gate. The angle and consistency of the electrode entering the mold steel plate, even if it can be leveled and aligned to ensure the entry angle, will definitely prolong the processing time, and the structure of one mold with multiple cavities is difficult to ensure the consistency of multiple cavities

And due to the level of experience of the staff's operation, the quality of the gate also fluctuates, which in turn leads to fluctuations in product quality.
