Description
Technical field
The present invention relates to die casting field, more particularly to a kind of castingin imitate type nickel core Glass Mould of Alloy Cast Iron and
Its manufacture method.
Background technology
With the continuous improvement of China's Living consumption, while domestic glass bottle product quantum of output significantly increases,
For the appearance requirement also more and more higher of glass bottle products；And the surface smoothness of glass bottle products arises directly from glass
The surface smoothness of dies cavity.The surface brightness of glass mold inner chamber then depends primarily on the metal casting for making glass mold
Part material.
Mainly there are Heat Resistant Cast Iron, heat-resistance stainless steel and heat-resisting currently used for the metal material for making glass die blank
Copper alloy etc..Wherein heat-resistance stainless steel is mainly used in terms of making the moulds such as glassware, glass lamp decoration；Copper alloy has because of it
There are good heat conductivility, anti-oxidant, high temperature resistant, heat-resistant anti-fatigue and not easy to break, abroad in terms of glass mold making
It is widely used.Because its cost is higher than common alloy cast iron material 3~5 times, at home glassware enterprise because into
This is too high not to be used generally, the country only have a small number of scales and the big vial product producer of strength produce long line or
Copper alloy mouth mold, bed die and copper alloy mould can be used during the high-grade bottle can product of person outlet.Heat Resistant Cast Iron is still
It is the major metal material for making glass die blank.
Heat Resistant Cast Iron material surface hardness is relatively low, in use easy washing away and mould because of high temp glass liquation
Between collide with, cause the surface portion of mould into blank mould joint surface, mouth mold, choma and drift, fuse to damage, serious will lead
Mould is caused to scrap in advance.It is heat-resisting producing in order to increase the case hardness and decay resistance of mold cavity and joint close junction
, need to be into blank mould joint surface, mouth mold, choma and drift, core surface surfacing hardness very high nickel alloy during alloy cast iron mould
Powder.Because nickel quality hard wear resistant, fire-resistant oxidation resistant, with good corrosion resistance, and being capable of high polish.Adopt
Turn into the best method for improving Heat Resistant Cast Iron glass mold performance with Ni alloy powder surfacing.Originally using spray by hand
Weldering, surfacing effect and operating efficiency depend entirely on the skills involved in the labour of operator, waste product, and efficiency easily occur
Low, working strength is big.Develop into and carried out automatic Welding with plasma spraying welding equipment, equipment and technique are all ripe,
And generally used by vast glass mold manufacturer.
Glass mold manufacturer of the country mainly uses the six Shaft and NC Machining Test plasma moulds spray of Italy's production at present
Soldering equipment and Ken Nasitaili metals（Shanghai）The plasma surfacing machine of Co., Ltd's production.The plasma nickel alloy of glass mold
Powder Spray is that required surfacing position first is machined away into the size than 2~3mm of surfacing layer depth, and the position of surfacing, which is not reserved, adds
Spare time measures；Then surfacing mould will be needed to carry out pre-heating, reach is needing surfacing position progress etc. again after the temperature of preheating requirement
Ion Ni alloy powder built-up welding.By mould annealing electric furnace annealing after surfacing, to eliminate internal stress.Then will be by annealing
Die blank afterwards goes to job shop and carries out surfacing post-processing, removes the excessive nickel alloy component of surfacing, reaches size requirement
Go to finishing step again afterwards.That is Ni alloy powder is carried out to Glass Mould of Alloy Cast Iron with plasma spraying welding equipment
The process of surfacing have to by：Milling surfacing groove~spray weld preheating~plasma spray~surfacing after annealing~surfacing post-processing
This several procedure of surfacing position.The process-cycle of surfacing mould is long, it is difficult to reach vial manufacturer in order to which product seizes city
And propose mould deliver duration problem.
Due to before plasma spraying welding equipment surfacing mould, it is necessary to mould is carried out into pre-heating, and to the preheating temperature degree of accuracy
It is required that higher.Surfacing quality can be influenceed by not reaching preheating temperature, and producing the surfacings such as stomata, sand holes in spray coating of alloy powder layer lacks
Fall into, cause surfacing mould to scrap.Plasma spraying welding equipment is to control nozzle by numerical control program（Spray gun）According to pre-set
Surfacing route and layer thickness, to mould carry out progressive scan formula surfacing.When needing surfacing position narrow width, such as surfacing mould
It is uniform with surfacing steady quality, layer during into blank mould, the upper and lower opening of mouth mold, bad mold joint and the small drift of surface area, fuse,
The advantage of surfacing efficiency high.But when carrying out the large area surfacing such as full surfacing in mouth mold inner chamber and the full surfacing of shaping mold cavity, due to
It is to come and go the covering that surfacing line by line carries out large area by straight line, it is from position cooling remote with a distance from welding gun substantially, near from a distance from welding gun
Spot temperature it is very high, the excessive temperature differentials at same each position of surfacing mould, easily inside the junction of every row spray-welding coating produce
Trickle sand holes and stomata even crackle, cause full surfacing mould to be scrapped.Require that nickel is closed now with many foreign customers in addition
Each part thickness of the nickel layer of golden powder spray welding mould wants uniformity, and layer shape will be with mouth mold or the cavity shape of mould
In imitative type state.This requirement is that plasma spraying welding equipment surfacing is unapproachable, because the welding gun of plasma spraying welding equipment will
The surfacing groove location that the welding mould to be painted of set point of temperature will be first preheating in advance continues to heat, and makes mother metal surface close to molten condition
When fill-before-fire Ni alloy powder welding powder, and continue to heat and the bound fraction of welding powder and mother metal is fully merged, the thickness of layer is difficult
To control.
So needing to change plasma spraying welding equipment surfacing pattern, using a kind of new technique and route, solve above-mentioned
The drawbacks of prior art is present, the present inventor contemplates imbedding process first, because copper alloy mouth mold castingin nickel core technique is introduced certainly
The U.S. and Taiwan, are in the industry cycle ripe technique already at present.And alloy cast iron castingin nickel core is complicated because of its casting technique, it is difficult to
Grasp, do not there is successful precedent also so far.In copper alloy mouth mold castingin nickel core technique, the pouring temperature of copper alloy 1230~
1260 DEG C of intervals are easy to shaping, and because containing the alloys more low-melting than nickel such as fluxing boron and other silicon, chromium in the material of nickel core
Element, fusing point is 1420 DEG C or so, and surface initial melting temperature is at 1360 DEG C or so.In copper alloy castingin nickel core, nickel core is closed in copper
Golden parent only produces slight frit reaction on surface, so being easy to grasp, yield rate is very high.And the pouring temperature of alloy cast iron
Between 1320~1380 DEG C, yield rate is extremely low during less than 1330 DEG C.So when pouring into a mould alloy cast iron castingin nickel core for pouring
The requirement for noting temperature is stricter, it is difficult to precisely control.The pouring temperature of alloy cast iron liquation is too high, and nickel wicking surface will be produced
Fusing is excessive, or even is completely melt, causes castingin to fail；The pouring temperature of alloy cast iron liquation is too low and is difficult to pour and outpours into
Product.In view of the drawbacks of above-mentioned prior art is present, the present inventor after it have passed through long-term research of technique and actually attempt to experiment,
Finally the vantageous methods for solving problem above are have found, and ultimately form the present invention by the technical scheme of offer.
