Abstract
The invention discloses a kind of casting method of metal implements.It comprises the following steps：A, molding, the model of casting is made with beeswax, makes outer model and loam core fit formation die cavity；B, preheating, outer model and loam core fit are first heated with warm fire, Slow cooling, are then put into stove high-temperature heating；C, cast, cast gate is injected by the copper liquid of fusing, after after the solidification cooling of copper liquid, you can remove model, core, take out copper base casting；D, copper base polishing；F, modification and surface coloring, are modified product after polishing, and surface coloring is finished product after product is modified.After adopting with the aforedescribed process, the casting being made of outer model and loam core is set to be not easily broken and occur sand holes, the preheating of outer model and loam core causes copper liquid mobility to be improved, so that the copper liquid energy being injected into die cavity is enough filled uniformly, the density and hardness of finished product is added, its rational technique causes the bronze, brass or copper ware being made in addition, surface is fine and smooth, moulding is exquisite, exquisitely carved, with good ornamental value.
Description
Technical field
The present invention relates to a kind of manufacture method of copper skill product, specifically a kind of hot investment casting side of metal implements
Method.
Background technology
Copper skill product by people due to very high ornamental value, in all age all extensively being liked, and copper skill product
Technique is also to be continued into the present from Gu, although the development of prior art, the technique of copper skill product is also progressively improved, different
The technique that copper skill product are used is also diversified, however, as the improvement of people's living standards, people are to copper skill product
Also more and more higher, existing copper skill product production technology are and existing, it is necessary to be further improved for the requirement of exquisite sophistication
A variety of copper skill product manufacture crafts, due to concrete technology in its preparation process（Such as toast, pour）Step has flaw, one
Aspect, it may appear that rupture and sand holes, still further aspect, density and hardness not enough, are easily deformed, another further aspect, it is impossible to obtain high
Exquisite degree, the requirement of high sophistication.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of surface quality is high, density and hardness is good and fineness degree and exquisiteness
The casting method of the high metal implements of degree.
In order to solve the above-mentioned technical problem, the casting method of metal implements of the invention, comprises the following steps：
A, molding
The model of casting is made with beeswax, is then applied with pug and outer model is made outside model, while with one volume of pug system
The loam core suitable with container intracavity, after finally heated baking, all fusing is lost in cere, makes outer model and loam core fit formation type
Chamber；
B, preheating
Outer model and loam core fit are first heated with 80-90 DEG C of warm fire, Slow cooling 30 minutes, then puts after heating 1-2 hours
Enter the high-temperature heating that stove passes through 300-400 DEG C；
C, cast
After high-temperature heating, the copper liquid of fusing is directly injected into cast gate in outer model and loam core with higher waste heat supply temperature,
After after the solidification cooling of copper liquid, you can remove model, core, take out copper base casting；
D, copper base polishing
Polishing is polished to the surface of copper base casting, makes copper base cast(ing) surface that there is smooth surface；
F, modification and surface coloring
Product after polishing is modified, metallic paint is sprayed on product by product after being modified, and makes its not oxidized, then is put
Enter baking box and bake 110-150 DEG C, then further take out cooling, as finished product.
The outer model is divided into several piece outer model is taken off from model after being made.
After adopting with the aforedescribed process, because outer model and loam core have carried out the pre-heat treatment of two kinds of different disposal temperature, make outer
Model and loam core hardness itself are higher, the casting being made of outer model and loam core is not easily broken and occur sand holes, in addition copper
Liquid causes copper liquid mobility to be improved being directly injected into cast gate, the preheating of outer model and loam core after high-temperature heating, so that
The copper liquid energy being injected into die cavity is enough filled uniformly, adds the density and hardness of finished product, and its rational technique causes system in addition
Into bronze, brass or copper ware, surface is fine and smooth, and moulding is exquisite, exquisitely carved, with good ornamental value.
Embodiment
With reference to embodiment, the casting method of the metal implements of the present invention is made further specifically
It is bright.
The casting method of the metal implements of the present invention, comprises the following steps：
A, molding
The model of casting is made with beeswax, is then applied with pug and outer model is made outside model, outer model is divided into several piece after being made
Outer model is set to be taken off from model, while with one volume of pug system loam core suitable with container intracavity, after finally heated baking, wax
All fusing is lost in film, makes outer model and loam core fit formation die cavity；
B, preheating
Outer model and loam core fit are first heated with 80-90 DEG C of warm fire, Slow cooling 30 minutes, then puts after heating 1-2 hours
Enter the high-temperature heating that stove passes through 300-400 DEG C；
C, cast
After high-temperature heating, the copper liquid of fusing is directly injected into cast gate in outer model and loam core with higher waste heat supply temperature,
After after the solidification cooling of copper liquid, you can remove model, core, take out copper base casting；
D, copper base polishing
Polishing is polished to the surface of copper base casting, makes copper base cast(ing) surface that there is smooth surface；
F, modification and surface coloring
Product after polishing is modified, metallic paint is sprayed on product by product after being modified, and makes its not oxidized, then is put
Enter baking box and bake 110-150 DEG C, then further take out cooling, as finished product.
