Description

A kind of wheel hub casting mould of optimizing cooling effect

Technical field

The utility model relates to the wheel hub processing technique field, and particularly a kind of film-cooled heat that enlarges, accelerate cooling velocity simultaneously, to optimize the wheel hub casting mould of cooling effect.

Background technology

Existing wheel hub processing mode adopts casting or die casting usually, casting mould generally comprises patrix, bed die and Bian Mo, and the three surrounds a wheel hub die cavity, and patrix is mainly to the back of the body chamber profile effect moulding of wheel hub, the positive profile effect moulding of bed die to wheel hub, the limit mould is to wheel rim profile effect moulding.

Due to mould uneven thickness everywhere, mould itself will be affected with the cooling velocity of foundry goods, some thick large parts on spoke and bcad seats particularly, extremely easily form heat energy-saving position, the existence of heat energy-saving position can make hub cast produce thermal stress after solidifying, cause casting deformation, crackle etc.; As while adopting the casting mode, thermal center place aluminium liquid cooling but setting time and other place does not obviously wait, and hub cast there will be loose, cold shut, the defects such as pore.

The type of cooling of conventional cast process using is generally fixed point the wind hole is set, as the relevant position easily producing heat energy-saving position corresponding patrix, bed die and Bian Mo, the wind hole is set, then connect respectively airduct the wind hole is blown, make the position cooling velocity that the wind hole is set relatively fast.But in actual production process, digging of at first a plurality of wind hole is comparatively loaded down with trivial details, and the wind hole film-cooled heat of scattering device is less, still can't make preferably the heat balance at mould and each position of foundry goods, and be limited for the lifting effect of cooling velocity.

Summary of the invention

The technical problems to be solved in the utility model is, the mode of cooling duct is set by employing, increase film-cooled heat, make simultaneously on mould and the corresponding position of the comparatively thick macrostructure of hub cast, cooling effect gets a promotion, so with other position heat balance, the liquid cooling of balance aluminium is setting time but, thereby optimize the cooling effect of mould and foundry goods, eliminate issuable hot spot joint, avoid the generation of hub cast spoke back of the body chamber profile shrinkage cavity defect.

In order to address the above problem, the technical solution adopted in the utility model is specially: a kind of wheel hub casting mould of optimizing cooling effect, comprise patrix, bed die and Bian Mo, and described patrix, bed die and Bian Mo surround a wheel hub die cavity;

The wheel rim die cavity comprises the bcad seats profile, is provided with the 3rd cooling duct in the position to the moulding of bcad seats profile in the mould of limit;

Be communicated with respectively air inlet pipe on described the first cooling duct, the second cooling duct and the 3rd cooling duct, and all be provided with 1 with the windward hole on the first cooling duct, the second cooling duct and the 3rd cooling duct.

Further, in the utility model, the first cooling duct is provided with the first deep bead towards a side at wheel hub center; The second cooling duct is provided with the second deep bead towards a side at wheel hub center; The 3rd cooling duct top is provided with the 3rd deep bead.The setting of deep bead can make the cooling-air that blows out in the wind hole of cooling duct be back to by gear on the corresponding mould position of easy generation heat energy-saving position, and recycling of cooling-air can strengthen cooling effect.

Concrete, in the utility model, the shape of each cooling duct is all its place mould structure of adaptation and designs, and is intended to processing and installs more for convenience: because patrix is circle, and be non-die cavity zone above patrix, therefore the first cooling duct is annular, can connect 2 air inlet pipe on it; 2 air inlet pipe are connected on the radially two ends of the first cooling duct; 1 was uniformly distributed in for the first cooling duct week upwards with the windward hole;

The bed die outline is also circular, but because its below is mold base, only the base center is provided with through hole, therefore the second cooling duct is annular, the air inlet pipe that connects on it has 1 air inlet and is connected a gas outlet that is connected with the second cooling duct; 1 air inlet can pass from the mold base center, and 2 gas outlets lay respectively at the radially two ends of the second cooling duct; 1 was uniformly distributed in for the second cooling duct week upwards with the windward hole;

The limit mould of one cover wheel hub mould generally contains 2 with top mould module, and single limit mould module is generally arc, therefore the 3rd cooling duct is the arc of closed at both ends, its middle part is connected with air inlet pipe; 1 is uniformly distributed on the 3rd cooling duct with the windward hole.

The beneficial effects of the utility model are: the annular cooling duct of mould cooperation carries out cooling mode and has changed the type of cooling of wind hole fixed point in the past; The shape of first, second, and third cooling duct adapts to all respectively patrix, bed die and the design of Bian Mo mould structure, has enlarged air-cooled film-cooled heat, thereby has guaranteed the cooling effect of mould; Therefore can better make around spoke thermal center and thick large bcad seats,, vertically and on lateral solidification cooling velocity and more effective feeding faster being arranged, improve the particularly mechanical property at spoke position of wheel hub.And the mould in the utility model coordinates the structure fabrication Simple fast cost of air loop duct low.Efficiency is than original average the raising about 1 minute.
