Description
Technical field
The utility model is related to a kind of mould, specially automobile swing arm long-life precision die.
Background technology
Swing arm is the important component of automobile front suspension, it may be said that be on automobile in addition to engine and transmission device, most
Important and flower cost part.The structure and intensity of swing arm directly influence the stability of vehicle body.As suspension guiding and
Support, its deformation effect to wheel alignment reduces roadability.Current swing arm has punching press, cast iron, cast aluminium by manufacturing process
Deng, the widely used lower-cost punching press swing arm of general basic vehicle, with it is thin, even, light, strong the characteristics of, impact energy absorption
It is good, but be not suitable for manufacturing complex structure, have the workpiece of many inner-cavity structures；Casting can produce the more complicated swing arm work of shape
Part, is more suitable for middle and high end vehicle, and casting swing arm is more preferable than punching press swing arm in terms of antirust, precision holding and rigidity hardness holding,
It is more easily broken off rather than deformation（Micro-strain is difficult discovery, but influences intact stability）, wherein the cost of cast aluminium swing arm is again
Higher than cast iron swing arm.
From for the market angle of mass production, stamped technique disclosure satisfy that most of vehicle type structure design and pacify
Demand in all directions；And if cast swing arm high precision, whether design allow complexity, intensity, rigidity or use the longevity
Life aspect, better than punching press swing arm.Therefore, a kind of simple structure, high-precision automobile swing arm casting mould be in the urgent need to.
The quality of mould needs the reasonable of structure design.Additionally, the homogeneity of product of general cast member is not high, it is necessary to logical
Cross strict control process conditions to realize, precision is also an important aspect.By to pouring condition, running channel and filtration
Reasonable arrangement, and demoulding program simplification, it is ensured that motlten metal liquid well form, crystallization, improve cast
Quality and reduction are disturbed.And surface roughness high, hole and length tolerance can cause burr to increase, disposable finished product is influenceed to close
Lattice rate, or need to increase cost processing, cost of manufacture is improved, and product quality declines.It can be seen that, rational structure design and foot
Enough precision are to ensure the most important factor that automobile swing arm casting once succeeds with performance high.
