Description
Technical field
The utility model relates to aluminium alloy casting field, specifically refers to that aluminum alloy cast makes a kind of sand mold mould blast nozzle used in process.
Background technology
Along with the various vehicles of China improve day by day as the popularity rate such as automobile, motorcycle, facilitate the trip of people.The speed of the various vehicles is also more and more faster, and as high ferro, its speed has reached 500 kilometers/hour.Among this except the development of science and technology, also have benefited from the various spare and accessory parts lightweight that uses in the vehicles and high strength, aluminum alloy materials plays key player wherein.
Along with energy-saving and cost-reducing environmental protection becomes the theme of society, sustained economic development, the lightweights such as space flight communication, high ferro EMUs, new-energy automobile certainly will become the main trend of world industry development.Think automobile example: automotive light weight technology refers to by increasing automobile chassis weight and reduces the weight of miscellaneous part as far as possible, reach complete vehicle weight and reduce and turn avoid vehicle and travel unbalance object, realize vehicle and travel not only safety and steady but also save the energy.According to the study, automotive dead weight often reduces 10%, and oil consumption can reduce 5.5%, and fuel economy can improve 3%-5%, reduces discharge about 10% simultaneously.Thus, the loss of weight of automobile engine just one of main object becoming automotive light weight technology.Because aluminium alloy is by having very high machinery, physical property after heat treatment, and weight is only 1/3rd of iron, reach that quality is light, intensity is high, the requirement of corrosion-resistant, antifatigue, to be inevitable development trend so engine uses aluminum alloy spare part to substitute cast iron casting part.
The production of aluminium alloy castings, be unable to do without mould and mold pin, mould ensure that the outer shape of aluminium alloy castings and the consistent of design.Mold pin then ensure that position and the size of all size pin-and-hole in aluminium alloy castings, decreases post-production workload.
Mould is divided into metal die and sand mold mould by material.
Metal die has many advantages in Technological Economy:
(1) its foundry goods produced, its mechanical property ratio sand-cast is high, and its etch resistant properties and hardness also significantly improve;
(2) precision of foundry goods and surface smoothness higher than sand-cast, and quality and dimensionally stable;
(3) the liquid metals consumption of foundry goods reduces, and generally can save 15 ~ 30%;
(4) without sand or use sand less, generally Modeling Material 80 ~ 100% can be saved.
The weak point of metal die is:
(1) manufacturing cost is high;
(2) metal is airtight, easily causes the defect such as blow hold, the similar scarce material in edge;
(3) casting technique is comparatively complicated, needs strictly to control;
(4) inner complicated foundry goods cannot be cast, as automobile engine cylinder head etc.
And the pluses and minuses of sand mold mould are just in time contrary with metal die.
Therefore, use metal die and sand mold mould to combine, complicated aluminium alloy engine parts can be cast.Namely engine component profile adopts metal die, and the labyrinth of engine component inside uses sand mold mould, and namely smallclothes sand mold mould sticks in large part metal die, forms unitary mould and is used for Birmasil engine component.
Smallclothes sand mold mould adopts usually to be penetrated sand machine to penetrate sand shaping, and when penetrating the work of sand machine, the molding sand being added with curing agent penetrated in sand machine is injected in flask by compressed air, forms sand mold mould.Still have a small amount of molding sand to spill from blast nozzle when penetrating sand machine and shutting down, affect produced on-site and cause waste.
The applicant has applied for patent in 2011: a kind of blast nozzle (CN202062052U), X-shaped baffle plate is provided with between sand-shooting head and sand export, curved channel is formed between X-shaped baffle plate and sand-shooting head inwall, sand-shooting head and sand export is made not to have straightthrough port in vertical direction, and sand-shooting head bottom adds an annular groove and X baffle plate, molding sand is fallen on annular groove by four curved channels because of gravity, when accumulating to a certain amount of, limit the flowing of molding sand, stopping is flowed by molding sand, thus reach molding sand and do not flow, the effect of not overflowing; Like this, penetrate sand machine when not working, molding sand does not spill.Through using for many years, though find that it has above-mentioned advantage, but, also there are the following problems, is badly in need of improving, when penetrating sand machine and not working, penetrate sand machine pipeline and still there is residual compression at short notice, molding sand still has and spills on a small quantity, especially penetrates when sand machine does not work and needs movement to penetrate sand machine pipeline, facilitate carrying out of next program, move leakage when penetrating sand machine pipeline larger, pollute work on the spot environment, just can carry out further work after needing cleaning, reduce operating efficiency.On the other hand, because blast nozzle adopts steel manufacture, through the use in one period, molding sand at a high speed by blast nozzle, causes wearing and tearing to blast nozzle, channel widens of shaking out, also easily causes molding sand to spill on a small quantity for a long time.
Summary of the invention
In order to solve sand machine of the penetrating pipeline hourglass sand problem that prior art exists, the utility model proposes structure simple, a kind of sand mold mould blast nozzle easy to use.
The technical scheme that the utility model uses is as follows:
A kind of sand mold mould blast nozzle, it comprises sand-shooting head and sand export, it is characterized in that: between described sand-shooting head and sand export, be provided with hexagon baffle plate, forms curved channel between hexagon baffle plate and sand-shooting head inwall; At described sand-shooting head inner wall lower, be provided with annular groove; Described hexagon baffle plate upper surface is plane, and lower surface is provided with the annular boss matched with described annular groove, and annular groove and annular boss form the V-arrangement passage being communicated with sand export, and V-arrangement channel upper is communicated with curved channel.
Described sand-shooting head and sand export are integral type structure, employing engineering plastics manufacture, between the sand-shooting head of described hexagon baffle plate and integral structure and sand export, adopt dismantled and assembled structure, hexagon baffle plate adopts engineering plastics or steel manufacture, the preferred steel manufacture of hexagon baffle plate, and the frictional force between steel and molding sand is large, the supporting force to molding sand can be increased, anti-leak-stopping sand.
The beneficial effects of the utility model are:
1) be provided with hexagon baffle plate between sand-shooting head and sand export and form six curved channels, hexagon baffle plate lower surface arranges annular boss, matches with annular groove, increases molding sand through out-of-date resistance, anti-leak-stopping sand;
2) sand-shooting head and sand export make integral structure, and adopt engineering plastics manufactures, the surface that engineering plastics are smooth, can reduce molding sand through time frictional force, thus reduce the wearing and tearing for sand-shooting head and sand export.The preferred steel manufacture of hexagon baffle plate, the frictional force between steel and molding sand is large, can increase the supporting force to molding sand, also can anti-leak-stopping sand, hexagon baffle plate and between sand-shooting head and sand export, adopts dismantled and assembled structure, is convenient for changing hexagon baffle plate.
