Description
[technical field]
The present invention relates to water-soluble wax applied technical field, more particularly to one kind to have compared with high efficiency, and production cost
The water-soluble wax hollow wax matrix manufacture craft of low high finished product rate.
[background technology]
Modern lost-wax casting is the Main Means of current jewellery production, and investment wax casting is substantially in machining process
Hot investment casting, it is the manufacturing outstanding feature of present jewellery by the batch micro operations that hot investment casting is applied to jewellery, jewellery manufacture
Investment wax casting disclosure satisfy that the demand of batch production, can also take into account the change of style or kind, therefore manufacturing in jewellery
Occupy consequence in the mode of production, the casting method of lost-wax casting have vacuum pressing and casting, centrifugal casting, vacuum pressure casting and
Vacuum centrifugal casting etc., is the Main Means of current jewellery manufacturing industry medium quantity batch processing, and the general process of lost-wax casting is：By original
Mould (being usually silver plate) is surrounded with raw silica gel, and heated pressurization produces vulcanization, is pressed into Silicon moulds；With sharp blade by certain
After order cuts open glued membrane, silver plate is taken out；The casting into hollow pellosil, pellosil taking-up wax is opened after the wax solidification of liquid
Mould, wax-pattern is put into steel sleeve by certain way planting wax tree and is irrigated calcium plaster after being modified to wax-pattern；Calcium plaster is through taking out
Vacuum, air-set, after being dried by certain warm up period, melt metal and cast；Plaster mold is put into after metal cooling cold
Water is fried to be washed, and is taken out pickling, cleaning after casting, is cut blank and carry out tumbling；Inlayed again, be surface-treated after become finished product.
When producing special-shaped hollow workpiece using lost-wax casting technology, mould technology is all typically hung using silica gel, the silica gel hangs mould
Technology first makes Silicon moulds, then pours into the wax liquor of fusing in Silicon moulds, manual rotation's Silicon moulds, wax liquor is attached to silica gel
On mould, hollow wax-pattern is can obtain after wax liquor solidification；Wall thickness be present by wax-pattern hollow made from such a manufacture
The defects of uneven, fine pattern can not embody, but also can not realize comprehensive hollow, cause the weight of workpiece to increase, after
The waste product increase of continuous production link, so that cost increase；It is in uneven thickness additionally, due to wax-pattern, thickness of workpiece can not be made uniform,
So that the shrink of workpiece is serious, particularly big workpiece, washing shrinkage has reached 5%-8%, and can not also large-scale application in life
Production.
Based on above mentioned problem, the washing shrinkage of workpiece how could be preferably reduced, it is applied to life on a large scale
Production, those skilled in the art has carried out substantial amounts of research and development and experiment, and achieves preferable achievement.
[content of the invention]
To overcome the problems of prior art, the present invention, which provides one kind, to be had compared with high efficiency, and production cost
