Abstract

The present invention is the manufacture method that male finger-ring with diamond is joined the end, make ring profile wax-pattern earlier, other makes wax pattern of arc piece, by heating two wax-patterns are guarded against mould in conjunction with being fixed as one, will guard against on the cylinder that mould is fixed in the wax material again, cylinder places on the die holder, the nested metal body of die holder, and make plaster mold, heating makes wax-pattern fusing outflow in it, inserts moulding in the centrifuge again.Owing to be combined into the ring mould by wax pattern of arc piece and ring profile wax-pattern, therefore needn't resemble existent method needs the spreading paillon foil to cut into the arc sheet, makes and the ring seam with welding gun again, and not only manufacturing process is more easy, and does not have substandard products, improves the quality of product.

Description

Male finger-ring with diamond is joined the manufacture method at the end

The present invention relates to a kind of centre spinning method of incavation.

In existing various gold ornaments, ring accounts for its sizable ratio, and when wherein the in men's style ring that bores of edge is made, make earlier usually desire to do the swage of finished product shape, again this swage is placed square dies central authorities to clad around swage, form a rubber pattern with rubber material filling molding.Then by cutting in the middle of the rubber pattern swage is taken out, making has a space of desiring manufactured goods in the middle of this rubber pattern again.With a wax injector wax juice is injected in the rubber pattern again, treat promptly to form a wax-pattern after wax juice solidifies, then wax-pattern is fixed on the cylinder made from the wax material one by one, and this cylinder is nested in the middle of the die holder of a rubber material, this die holder periphery also is provided with a recessed annular groove, hollow tube with an iron and steel material quality is intercalated in the annular groove place, make the cylinder of fixing densely covered wax-pattern cladded in the body inboard, pour into gypsum by body upside opening part again and fill up all spaces in the body, treat after the gypsum sets die holder to be taken off by the body bottom side, and body is heated.Because the fusing point of wax is low than gypsum, therefore cylinder and wax-pattern just are molten into wax juice by flowing out in the gypsum, and form a plaster mold, again plaster mold and Jinsui River are placed in the centrifuge, the rotation of mat centrifuge is entered very equably as the space in the plaster mold Jinsui River, after it is taken out the immersion cooling, promptly can gypsum be sprayed spray gun, make formation one cylinder ring periphery fix densely covered ring, at last ring is just finished preliminary program by cutting away on the cylinder.

Because above-mentioned ring is bigger, general all is hollow, so when making swage, ring face downside broad general goal bottom side is with the finger contact position and can't have a cambered surface, its edge is comparatively sharp, though the ring finished product of then making can make it comparatively slick and sly but still be easy to the incised wound finger through grinding, or, be easy to cause the damage of this place's skin because flushing causes water to lodge in ring and hand when middle.For this reason, be to be laminar goldleaf with the gold spreading again, and make and guard against the arc sheet of face head bottom side, cooperate welding agent to be welded on the ring this arc sheet again with welding manner with shape through the cutting bending.This kind mode is owing to the reason of welding agent causes it to become branch to reduce, and welding agent causes forming stain and the quality of finished product being reduced at weld sometimes.In addition, also have the arc sheet after the spreading bending directly burnt with the nozzles weldering after involutory and make it fusion.Though this kind mode does not have the shortcoming of using welding agent, because of desiring to make its fusion need higher temperature, technological requirement is higher, careless slightlyly promptly forces side or end face thin location also thereby fusion, causes yield rate to reduce.Simultaneously, have when making rubber pattern, when promptly trying to make model, owing to can't the demoulding can't resolve the problems referred to above with bottom.

The object of the present invention is to provide a kind of method easy, the higher male finger-ring with diamond of yield rate is joined the manufacture method at the end.

Its concrete grammar is the wax-pattern that makes the ring external form earlier, make a wax pattern of arc piece with identical method in addition, by the heating with wax pattern of arc piece combine with ring external form wax-pattern be fixed as one the ring mould, the ring mould that to finish again is fixed on the cylinder of wax material one by one, simultaneously this cylinder is inserted in the mesopore place of a die holder, and at the nested metal body of die holder outer rim, and fill out the filling gypsum and make plaster mold, the plaster mold heating is made wax-pattern fusing outflow in it, again it is inserted moulding in the centrifuge.

The present invention is by increasing by a wax pattern of arc piece, make again with ring external form wax-pattern and be combined into the ring mould, therefore needn't resemble existent method needs the spreading paillon foil to cut into the arc sheet, make and the ring seam with welding gun again, not only manufacturing process is more easy, and do not have the substandard products generation, improve the quality of product and reduced cost.

Fig. 3 is a goods finished figure of the present invention.

Embodiment: as shown in Figure 1 to Figure 3, when adopting existent method to prepare the wax-pattern (1) of ring external form, make a wax pattern of arc piece (2) with identical method in addition, by the heating with wax pattern of arc piece combine with ring external form wax-pattern be fixed as one the ring mould (3), the ring mould that to finish again is fixed on the cylinder (4) of wax material one by one, simultaneously this cylinder (4) is inserted in the mesopore place of die holder (5), and in the nested metal body (6) of the outer rim of die holder, can fill out the filling gypsum and become plaster mold, then the plaster mold heating is made wax-pattern fusing outflow in it, promptly insert moulding in the centrifuge, attrition process in addition after the moulding.

Claims

1, a kind of male finger-ring with diamond is joined the manufacture method at the end, make the wax-pattern of ring external form earlier, again wax-pattern is fixed on the cylinder of wax material one by one, simultaneously this cylinder is inserted in the mesopore place of a die holder, and at the nested metal body of die holder outer rim, and fill out the filling gypsum and make plaster mold, the plaster mold heating is made wax-pattern fusing outflow in it, insert moulding in the centrifuge again, after the invention is characterized in the wax-pattern that makes the ring external form, make a wax pattern of arc piece with identical method in addition, by heating wax pattern of arc piece is combined with ring external form wax-pattern again and be fixed as a ring mould, again this wax-pattern is fixed on the cylinder of wax material one by one.
