Description
Technical field
The present invention relates to casting technology field more particularly to a kind of processing sides of OEM aluminum-alloy wheel casting mould bed die
Method.
Background technique
Statement in this part merely provides background information related with present disclosure, thereby increases and it is possible to not constitute
The prior art.
The foundry engieering of aluminum-alloy wheel is varied, and aluminum-alloy wheel casting technique, at present there are mainly two types of, it is a kind of
It is gravitational casting, one is low pressure castings.The OEM of wheel point retail and main engine plants.At this stage, raw regardless of domestic or external
The lower mould for producing aluminum-alloy wheel is all made of hot die steel H13(SKD61), the service life of retail is generally 10,000 moulds, OEM
It is 30,000 moulds.After use, die surface corrodes mold, and cracking, die deformation etc., this is cannot to solve at present
The problem of.
Aluminum-alloy wheel casting mould in the prior art mainly includes upper die and lower die and bed die, upper die and lower die and
Bed die constitutes closed type chamber.When alloy wheel is cast, the molten aluminum injection type chamber of high-temperature fusion becomes vehicle after molten aluminum is cooling
Take turns product；When casting, due to temperature of aluminum liquid height, bed die wall body has certain thickness, causes bed die wall body internal-external temperature difference larger, make
At bed die thermal deformation；After casting, to reach up time solidification, bed die is sprayed onto bed die by cooling medium wind or water and carries on the back chamber, causes
Bed die instantaneous temperature difference becomes larger, and causes the cold and hot frequent alternating of bed die, bed die is caused to crack；After aluminum water casting, molten aluminum is full of bed die,
Bed die molding surface and aluminum water completely attach to, though bed die has spray protective coating, with the increase of mould time, Paint Falling causes bottom
Mould corrosion.
Therefore the prior art has much room for improvement and develops.
