Description
Technical field
This utility model is related to a kind of die casting exhaust structure, belongs to die casting field.
Background technology
Die casting is a kind of metal casting technique, is characterized in applying high pressure using mold cavity to the metal melting.Mould leads to
It is often to be processed with the higher alloy of intensity, some the similar injection mo(u)ldings of this process.Most of die casting foundry goods are all not
Iron content, such as zinc, copper, aluminum, magnesium, lead, stannum and terne metal and their alloy.According to the difference of die casting type, need
Cold-chamber die casting machine to be used or hot chamber machine.Existing die casting die is provided with exhaust structure, but existing
The exhaust structure of die casting is too fast due to exhaust velocity, leads to the pressure in perfusion of the metal liquid in mold cavity uneven,
Thus leading to finished product internal stress uneven, casting finished products intensity is affected.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of compression mod
Tool exhaust structure, reduces exhaust velocity, and exhaust velocity uniformly, improves the intensity of casting finished products.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of die casting exhaust structure, bag
Include fixed half and moving half, cover half is provided with cover half exhaust structure, dynamic model is provided with moving die exhaust structure；Described cover half aerofluxuss knot
Structure includes arranging some aerofluxuss projections with cover half die cavity edge, and moving die exhaust structure includes being arranged at dynamic model die cavity edge
Some exhaust grooves, aerofluxuss are raised and the cooperation of exhaust groove gap, and aerofluxuss are raised to form exhaust passage and exhaust groove between；
The sidepiece of described cover half block is provided with steam vent, and steam vent is connected with exhaust passage；Described exhaust groove is arc groove, aerofluxuss
Some arc auxiliary tanks are provided with the arc inner face of groove；Described exhaust passage rear is connected with a return flow line, returns
Circulation road and exhaust passage are in 28.5 degree of angles, and the two ends of return flow line are respectively arranged with a backflow cavity.
Optimize, above-mentioned die casting exhaust structure, the arc inner face of described arc auxiliary tank is provided with spoiler.
Optimize, above-mentioned die casting exhaust structure, in described back cavity body, be provided with some auxiliary projection.
Optimize, above-mentioned die casting exhaust structure, raised and exhaust groove the form fit of described aerofluxuss is arranged.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
It is provided with aerofluxuss projection and exhaust groove, and raised by aerofluxuss and exhaust groove gap has cooperatively formed aerofluxuss and led to
Road, due to there is the raised back-shaped structure being formed with exhaust groove of aerofluxuss in exhaust passage so that gas vent pathway extends, and
And because back-shaped structure makes air-flow can clash into the inwall of exhaust passage, reduce further exhaust velocity so that exhaust velocity
Uniformly.Arc auxiliary tank makes air-flow form vortex so that gas withdrawal rate is more uniform.Return flow line and the cavity that flows back
When setting makes exhaust airstream speed that fluctuation occurs, if speed is accelerated, air-flow enters backflow cavity storage by return flow line,
If crossing slow, the gas in back cavity body is flowed out by return flow line, stablizes exhaust gas flow velocity.The other structures of the application,
As pressurizeed, pouring, the structure such as die cavity, guiding identical with technical scheme of the prior art.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is mplifying structure schematic diagram at the A of Fig. 1；
In figure：1 is cover half, 2 is dynamic model, 3 be aerofluxuss raised, 4 be exhaust groove, 5 be exhaust passage, 6 be steam vent, 7
For arc auxiliary tank, 8 be return flow line, 9 be backflow cavity, 10 be spoiler, 11 be auxiliary projection.
Specific embodiment
Of the present utility model technical characterstic is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of die casting exhaust structure, including fixed half and moving half, cover half is provided with cover half aerofluxuss
Structure, dynamic model is provided with moving die exhaust structure；Described cover half exhaust structure includes arranging some with cover half die cavity edge
Aerofluxuss are raised, and moving die exhaust structure includes being arranged at some exhaust grooves of dynamic model die cavity edge, and aerofluxuss are raised and aerofluxuss are recessed
Groove gap coordinates, and aerofluxuss are raised to form exhaust passage and exhaust groove between；The sidepiece of described cover half block is provided with steam vent, row
Pore is connected with exhaust passage；Described exhaust groove is arc groove, and the arc inner face of exhaust groove is provided with some arcs
Shape auxiliary tank；Described exhaust passage rear is connected with a return flow line, and return flow line and exhaust passage are in 28.5 degree of angles, return
The two ends of circulation road are respectively arranged with a backflow cavity.It is provided with spoiler on the arc inner face of described arc auxiliary tank.
It is provided with some auxiliary projection in described back cavity body.Raised and exhaust groove the form fit of described aerofluxuss is arranged.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
It is provided with aerofluxuss projection and exhaust groove, and raised by aerofluxuss and exhaust groove gap has cooperatively formed aerofluxuss and led to
Road, due to there is the raised back-shaped structure being formed with exhaust groove of aerofluxuss in exhaust passage so that gas vent pathway extends, and
And because back-shaped structure makes air-flow can clash into the inwall of exhaust passage, reduce further exhaust velocity so that exhaust velocity
Uniformly.Arc auxiliary tank makes air-flow form vortex so that gas withdrawal rate is more uniform.Return flow line and the cavity that flows back
When setting makes exhaust airstream speed that fluctuation occurs, if speed is accelerated, air-flow enters backflow cavity storage by return flow line,
If crossing slow, the gas in back cavity body is flowed out by return flow line, stablizes exhaust gas flow velocity.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this
