Description
Technical field
The present invention relates to a kind of method and processing unit (plant) thereof of on mould, processing arc orbit tunnel hole.
Background technology
On some mould, need to design hole, arc-shaped rail tunnel sometimes, as the most common be so-called banana formula cast gate.At present, the method in processing hole, arc-shaped rail tunnel has three kinds on mould, a kind of is on most widely used single coordinate electric spark shaping mill (the English EDM of abbreviation), because this single coordinate electric spark shaping mill can only carry out the vertical feed campaign, so, when needs processing hole, arc-shaped rail tunnel, must earlier the die part in this hole of preparation processing be done a mold component separately, mold component cuts along hole, arc-shaped rail tunnel axial direction symmetry, make mold component become two parts, then with shape and size with need the corresponding to electrode in hole, arc-shaped rail tunnel of machine-shaping to be vertically mounted on single coordinate electric spark shaping mill, allow electrode move up and down, on the opposite face of two parts of mold component, erode away respectively hole, arc-shaped rail tunnel half, then, two parts with mold component are spliced into an integral body again, have just become a complete hole, arc-shaped rail tunnel, then this mold component are assemblied in the corresponding site of mould.The method operation more complicated in hole, this processing arc-shaped rail tunnel, and also has a quite insoluble problem, it is exactly produced in this way mould, the product of producing with this mould again, on the outer surface of product, can stay the splicing seams of mould, influence the outward appearance of product, but, because the equipment price of this single coordinate electric spark shaping mill is relatively cheap, so, a lot of Mould Machining producers all are furnished with this equipment, also with this method processing hole, arc-shaped rail tunnel.Second method is to utilize multi-coordinate such as three-dimensional, five coordinate electric spark shaping mills (also claiming three, five EDM), because this equipment can be three or five direction motions, so can process hole, high-quality arc-shaped rail tunnel, but this kind equipment generally has only integrated mill just can be equipped with owing to cost an arm and a leg, also just be mainly used to complex-shaped surface moulds such as processing revolution screw thread, swiveling gear, sidewise hole, be used to process its processing cost of hole, arc-shaped rail tunnel and also do not calculate.The third method is exactly to adopt the method for casting forming, utilize compression mod to come casting forming processing to have the goods in hole, arc-shaped rail tunnel exactly, this method only is suitable for the production of the goods that have hole, arc-shaped rail tunnel of extensive single size, because, open a cover compression mod, for small lot batch manufacture, the cost of its product can be very high, and every cover die can only design the size in hole, a kind of arc-shaped rail tunnel.
Summary of the invention
First goal of the invention of the present invention is to overcome the problems referred to above, a kind of processing method of arc orbit tunnel hole is provided to society, this method can realize at single coordinate electric spark shaping mill, and need not do the mold component that cuts away half separately, next uses this method, and no matter batch size can be processed, and how many costs can not increase.
Second goal of the invention of the present invention provides a kind of can the realization at single coordinate electric spark shaping mill, and need not do the mold component that cuts away half separately, and next uses this method processing unit (plant) no matter batch size can be processed.
