Description
Technical field
The present invention relates to a kind of casting method of wheel, more particularly to the casting of the motorcycle aluminium alloy wheel of hollow form wheel hub
Make method.
Background technology
In prior art, the wheel of motorcycle generally adopts the wheel hub of hollow form to mitigate weight, but in wheel hair
During the casting of base, in order to improve casting accuracy, wheel hub be generally cast into it is solid, therefore, when the machining of wheel is carried out, need
The wheel hub of wheel carried out drilling and be processed so as to reach the structure of hollow form, but the production technology of wheel is become
Obtain very loaded down with trivial details, improve the generation time of wheel, reduce the formation efficiency of wheel.
The content of the invention
Present invention seek to address that above-mentioned mentioned technical problem, there is provided high hollow of a kind of process is simple, production efficiency
The casting method of the motorcycle aluminium alloy wheel of shape wheel hub.
The present invention is realized by following technical scheme：The casting side of the motorcycle aluminium alloy wheel of hollow form wheel hub
Method, including the mould of bed die, Bian Mo and backform construction, comprise the following steps during casting：
Determine core step, core is fixed on into the middle part of bed die；
Matched moulds step, makes backform and Bian Mo be covered with bed die；
Cast step, by plug hole of the quantitative aluminium water from backform the die cavity that backform, Bian Mo and bed die are configured to is injected into
In；
Coagulation step, makes the sufficiently cool solidification of aluminium water in injection die cavity；
Demoulding step, opens backform and Bian Mo, and the foundry goods of coagulation forming is taken out from bed die；
Heat treatment step, foundry goods is heat-treated, and makes core come off from the wheel hub of foundry goods.
Preferably, the core is formed by quartz sand and mixed with resin.
Preferably, the temperature of the heat treatment is 535 DEG C -555 DEG C.
Preferably, before the centering step bed die, backform and Bian Mo are blown clean with air gun.
Preferably, the bed die middle part is provided with the mandrel positioned to core, is provided with core and coordinates with mandrel
Through hole.
Preferably, it is described cast step in, by aluminium water inject die cavity when before, on the plug hole of backform arrange filter
Net.
Preferably, in the cast step, when aluminium water injects die cavity, a small amount of aluminium water is contained with container standby.
Beneficial effect is：Compared with prior art, the casting method of the motorcycle aluminium alloy wheel of hollow form wheel hub passes through
Core is set on bed die so that formed after foundry goods after the solidification of aluminium water cooling, core is wrapped at hub for vehicle wheel, and by heat
The mode of process so that core is backing out from wheel hub in hot environment, forms hollow form wheel hub, such casting method
So that wheel when being machined out without carrying out hollow process to wheel hub, reduce production process, improve formation efficiency,
Reduce production cost.
Specific embodiment
The casting method of the motorcycle aluminium alloy wheel of hollow form wheel hub, comprises the following steps successively：
Determine core step, core is fixed on into the middle part of bed die, prevent core position in casting process from shifting；
Matched moulds step, makes backform and Bian Mo be covered with bed die so that backform, Bian Mo and die block construction into wheel blanks
Shape identical die cavity；
Cast step, by plug hole of the quantitative aluminium water from backform the die cavity that backform, Bian Mo and bed die are configured to is injected into
In；
Coagulation step, makes the sufficiently cool solidification of aluminium water in injection die cavity；
Demoulding step, opens backform and Bian Mo, and the foundry goods of coagulation forming is taken out from bed die；
Heat treatment step, foundry goods is heat-treated, and core is taken off from the wheel hub of foundry goods in high temperature environments, in being formed
The wheel hub of empty shape, so that wheel, without carrying out hollow process to wheel hub, reduces production process when being machined out,
Formation efficiency is improve, production cost is reduced.
Core can be formed by quartz sand and mixed with resin, and resin has viscosity, quartz sand can be bonded into fixed shape
The core of shape, and viscosity is kept in the environment of resin can be less than 500 DEG C, so that core will not be broken in the cast of aluminium water
Split.
The temperature of heat treatment can be 535 DEG C -555 DEG C, and the viscosity that can so cause resin disappears, so that core is broken
Split, and the wheel hub from wheel foundry goods is separated, and forms the wheel hub of hollow form, and in 535 DEG C -555 DEG C of temperature conditionss
Under, the hardness of foundry goods has obtained great lifting, makes foundry goods meet hardness standard after heat treatment.
Bed die, backform and Bian Mo can be blown clean with air gun before centering step, so can be prevented in cast aluminum water
During, aluminium water mixes with dust particale or other impurities on bed die, backform either side mould so that aluminium water cooling solidifies
Form husky hole in foundry goods afterwards or be mixed with other impurities.
Bed die middle part can be provided with the mandrel positioned to core, and the through hole coordinated with mandrel is provided with core,
Coordinated with the mandrel being arranged in the middle part of bed die by the through hole on core, it is possible to achieve the stable position to core, it is ensured that
Core will not occur the phenomenon of position skew in aluminium water casting process.
Cast step in, by aluminium water inject die cavity when before, screen pack can be set on the plug hole of backform, so may be used
Impurity in place aluminium water is entered in die cavity, it is to avoid aluminium water cooling solidifies to be formed after foundry goods, there is husky hole or mixed in foundry goods
There is the phenomenon of impurity.
In cast step, when aluminium water injects die cavity, can be standby with a small amount of aluminium water of container splendid attire, due to the aluminium poured into a mould
The amount of water is all quantitative, and only more than the amount of aluminium water needed for one foundry goods of casting, uses and easily contains a small amount of aluminium water,
So that then the aluminium water in container is slowly injected into die cavity by the aluminium water in injection die cavity less than the amount of one foundry goods of casting with hand
In so that the aluminium water yield just enough casts the amount of a foundry goods, so can avoid in casting process, injecting in die cavity excessive
Aluminium water.
Above example is only not limited to illustrate technical scheme, all without departing from the present invention
Any modification of spirit and scope or equivalent, it all should cover in the range of technical solution of the present invention.
