Description
Technical field
This utility model relates to casting mould, relates in particular to wheel cast mould.
Background technology
At present, aluminum-alloy wheel manufactures main employing low pressure casting production technology, owing to whole mold system is in a relatively open atmospheric environment all the time, adds the characteristic that aluminium alloy is oxidizable, make oxide slag inclusion become one of common defect of wheel foundry goods.This defect reduces the consistency of product tissue, weakens the integrity of foundry goods, does not often reach the use requirement of client in the mechanical property of wheel and service life, and X-ray check is difficult to be found simultaneously, therefore endangers the biggest.In wheel actual production, typically by arranging exhaust air plug at backform inner rim and offer line and to be discharged by the air in die cavity as far as possible, to reduce aluminum liquid oxidation degree, but fact proved effect inconspicuous.
The above analysis, in order to oxide inclusion defects aluminum-alloy wheel produce in is preferably decreased or even eliminated, it is necessary for fundamentally solving the air residue problem in die cavity, by being that aluminium alloy liquid fills type and creates a good environment by some effective means, and this also becomes the important topic that engineers and technicians are urgently to be resolved hurrily.
Summary of the invention
The technical solution of the utility model is: low-pressure casting die of aluminium alloy wheel exhaust apparatus, including controlling main frame, connection line, gas storage sites, air pipeline, inlet valve, venting plug, air inlet line, aerofluxus line, little airduct.Controlling main frame to be connected with gas storage sites by connection line, gas storage sites is connected with inlet valve by air pipeline.Inlet valve is arranged on bed die window position；Being attached inside air pipeline by inlet valve, outside is then connected to gas storage sites by circuit.When control panel button makes mould start descending matched moulds, device Host system will send and instruct to gas storage sites, and automatically open up the container control valve holding noble gas, and gas is entered inside die cavity by bed die inlet valve under pressure；After a liter liquid stage completes, control valve can be closed by time controller within main frame automatically, thus completes gas transmission；Arranging exhaust air plug at inner rim, when making aluminum liquid filling type, type intracavity gas can be discharged smoothly, thus avoids the formation of internal counter-pressure, and liquid will not be hindered to fill type.By above-mentioned measure, it is possible to ensure that filling the type stage at high temperature aluminum liquid, whole mold cavity are in the protection atmosphere of a noble gas, it is to avoid aluminum liquid directly contact with oxygen, reduces the probability of oxide slag inclusion appearance.
The quantity of inlet valve is 1-3, and inlet valve one end arranges external screw thread, and inlet valve internal diameter is 5mm-8mm.
Arranging air inlet line on inlet valve, air inlet line quantity is 3-6 bar, width 0.2-0.3mm, highly 10-20mm, and air inlet is scribed ss noble gas and enters the passage of die cavity.Venting plug is notch cuttype, and venting plug arranges aerofluxus line, and aerofluxus line quantity is 3-6 bar, width 0.2-0.3mm, highly 10-30mm, aerofluxus is scribed ss air and the passage of noble gas discharge die cavity, avoid formation inner chamber back-pressure, and hinder aluminum liquid fill type smoothly.Air pipeline is arranged to single tube pair and enters, and makes gas can be passed through more uniformly and be full of die cavity；Use between air pipeline 4 with inlet valve 5 and weld or threaded.Noble gas may select argon or nitrogen two kinds, and air pressure is set as 0.2-0.6Mpa.
This utility model advantage is: be reasonably incorporated into inside casting mould die cavity by ambient pressure by noble gas, air by discharge type intracavity in advance, make high temperature aluminum liquid can complete cavity filling process in the environment of a relative anaerobic, avoid aluminum liquid to contact with the direct of oxygen, it is effectively controlled the probability that oxide inclusion defects occurs during wheel cast, the internal soundness making foundry goods is greatly improved, and also there have been obvious improvement in mechanical property and service life.Meanwhile, the design of this structure is simple, it is easy to accomplish.
