Abstract
The invention relates to a method for manufacturing a metal accessory through die-parting formation. The method comprises the following steps of: making manual original components; making rubber dies; making wax blanks; making wax trees; making gypsum dies; forming the components; and welding and forming an accessory. According to the method provided by the invention, especially, the die-parting formation of the components is adopted, the efficiency is improved, the defective rate is reduced, and the characteristics of clear patterns and textures and good consistency of produced accessories are achieved, therefore the method is suitable for the formation of large-sized and complex-molded metal accessories in batch quantity, and is also suitable for the need of production of various metal and mechanical parts in small batches.
Description
Technical field:
The present invention relates to a kind of metal decoration and divide the mold forming preparation method, especially a kind of dewax fusible pattern technology of passing through is divided mold forming by parts, then is assembled into the method for complete ornaments, especially is suitable for making complicated and large-scale metal decoration.
Background technology:
Existing dewax fusible pattern technology extensively applies to the making of jewelry, and the especially one-shot forming of small-sized ornaments such as bracelet and ring brings great convenience and efficient to batch process.At relatively large ornaments or more bulk ornaments, it must take bigger plaster mold space, and production efficiency is low, if adopt the overall time moulding, is difficult to guarantee molten metal water, can flow to each corner of runner far-end, can increase defect rate undoubtedly.
Summary of the invention:
After the objective of the invention is to invent a kind of metal decoration and dividing mold forming, be welded into whole high desnity metal ornaments again and divide the mold forming preparation method.
Technical solution of the present invention is achieved in that a kind of metal decoration divides the mold forming preparation method, it may further comprise the steps: make tablet held before the breast by officials, make rubber moulding, make the wax base, make wax tree, make plaster mold, parts moulding, ornaments welding fabrication, it is characterized in that:
One, make tablet held before the breast by officials: the metal decoration master that manually designs and produces, the maximum closeness during according to the making plaster mold splits into some parts with master;
Two, make rubber moulding: by glue laminated, sulfidization molding, table has the rubber moulding that master texture shape and middle part have the casting mouth in making, and takes out master with gained master parts;
Three, make the wax base: the paraffin of perfusion hot melt in rubber moulding, badly take out wax after waiting to solidify in rubber moulding;
Four, make wax tree: on the candlestick that stands vertically, the above-mentioned prepared wax base of intensive layer by layer welding forms wax tree;
Five, make plaster mold: above-mentioned wax tree is put into a metal sleeve, perfusion pulpous state gypsum in sleeve, and integral body put into the vacuum equipment extracting air, treat gypsum sets after, move in the firing equipment, promptly get plaster mold behind the dewax;
Six, parts moulding: plaster mold moves into the baking box preheating, oven temperature rises to more than 800 ℃, keep more than 10 minutes, make the plaster mold heat penetration, the taking-up plaster mold also moves in the lift pump, pours into the liquid metal water of fusing in plaster mold at once, naturally after the cooling, with the plaster mold fragmentation, isolate parts;
Seven, ornaments welding fabrication: after the parts that the make cleaning, the reverse operating in set by step is in fractionation place welding or be assembled into complete metal decoration.
Carry out grinding process on the metal decoration surface that above-mentioned steps seven makes, then at surperficial plated with gold or silver metal.Make metal decoration have the appearance luster of gold or silver.
The present invention has that the ornaments pattern texture that technological design is reasonable, the high defect rate of efficient is low, produce is clear, the characteristics of high conformity, be fit to the batch moulding of the metal decoration of large-scale and complex model, also can be fit to the need of the small lot batch manufacture of each metalloid machine components.
The specific embodiment:
Metal decoration divides the preparation method of mold forming, is example to produce the peony bracelet in batches, and this bracelet middle part disjunctor has a peony, four layers of varying in size of petal branch, the every layer of lobe that successively successively decreases from bottom to top forms for the copper wicking surface is silver-plated, and its making step is as follows:
The first step, make tablet held before the breast by officials: the bracelet ornaments master that manually designs and produces, perhaps select ready-made product handsome in appearance, bracelet main body and peony fractionation, peony layering are torn open, split out five kinds of parts altogether;
In second step, make rubber moulding: by glue laminated, sulfidization molding, table has the rubber moulding that master texture shape and middle part have the casting mouth in making, and takes out master with gained master parts;
In the 3rd step, make the wax base: the paraffin of perfusion hot melt in rubber moulding, badly take out wax after waiting to solidify in rubber moulding;
The 4th step, make wax tree: with above-mentioned five kinds of parts wax bases that make, make wax tree respectively, also promptly with wax parts wax base is welded in that layering around the vertical candlestick is intensive, form highdensity parts wax tree, this moment, the weld part of wax promptly became metal flow passage;
The 5th step, make plaster mold: the wax tree of above-mentioned making is put into a metal sleeve, the wax tree of different sizes is selected the metal sleeve of different bores, perfusion pulpous state gypsum in sleeve, and integral body put into the vacuum equipment extracting air, after treating gypsum sets, move in the firing equipment, dewax promptly gets the plaster mold of five kinds of parts; Dewax can adopt the high-temperature steam dewax, perhaps moves into baking box high temperature dewax.
The 6th step, the parts moulding: plaster mold moves into the baking box preheating, oven temperature is raised to 800 ℃ to 1000 ℃, keeps 15 minutes, makes the plaster mold heat penetration, the taking-up plaster mold also moves in the lift pump, in five kinds of plaster molds, pour into the liquid copper water of fusing respectively, naturally after the cooling, with the plaster mold fragmentation at once, isolate five kinds of parts, the metal flow passage during also promptly along design is cut off.Consider continuity production, the dewax of plaster mold and preheating also can unite two into one, and directly adopt the baking box dewax, and oven temperature is grown to more than 800 ℃, reach dewax and preheating dual purpose.
In the 7th step, the ornaments welding fabrication: after the parts that the make cleaning, the reverse operating in layer welds peony petal set by step, and then being welded on becomes complete product again on the bracelet main body; Perhaps peony petal is in layer stacked, by a steady pin or screw locking on the bracelet main body.
With above-mentioned the 7th metal decoration one bronze medal peony bracelet that makes of step, grinding process is carried out on the surface, then at surperficial plated with gold or silver metal, gold bracelet or silver bracelet.
In this technology, with each parts of peony bracelet separately, be convenient to intensive layer by layer weldering wax tree, and select the metal sleeve of different bores according to different parts, not only the efficient height is saved the material in each link, also can reduce defect rate.
