Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art, the mould that is used for the wheel hub casting that provide that a kind of mould quality of fit is high, rub proofness is high, be difficult for producing burr and overlap, casting quality is good.
Technical solution of the present utility model is; following a kind of mould for the wheel hub casting is provided; the upper die and lower die plate that comprise cope match-plate pattern, is connected with cope match-plate pattern, the counterdie that is connected with lower bolster, side form slide block, the side form that is connected with the side form slide block; described cope match-plate pattern both sides are provided with boss; described boss directly cooperates with the side form end face; adopt the facade land area between described patrix and the side form; described lower bolster both sides are provided with boss; described boss directly cooperates with the side form bottom surface, adopts the inclined-plane land area between described side form and the counterdie.
Adopt above technical scheme, described cope match-plate pattern both sides are provided with boss, described boss directly cooperates with the side form end face, having changed in the past, side form relies on patrix to carry out the mode of axial location, become the boss face that is provided with by the cope match-plate pattern both sides and carry out axial location, use cope match-plate pattern to carry out axial location, close mating surface when touching away from die cavity, eliminate the corrosion of the high hot aluminium alloy liquid of high temperature to mating surface, reduced the loading force that patrix bears, adopted simultaneously the facade land area between described patrix and the side form, close the power of touching larger, close that to touch matched in clearance more stable, improved to close and touched precision, reduced burr and overlap that this time wearing and tearing bring; Equally, described lower bolster both sides are provided with boss, described boss directly cooperates with the side form bottom surface, have reduced the high hot aluminium alloy liquid of high temperature in the die cavity to the corrosion of mating surface, have reduced overlap and burr; Adopt the inclined-plane land area between described side form and the counterdie, solved because side form is different from the bed die material, and the phenomenon of side form land area serious wear has reduced burr and overlap.
As preferably, the angle of inclination, inclined-plane of described inclined-plane land area is 10 ° ~ 15 °.Adopt the technical program, through facts have proved, the demoulding is convenient at the inclination angle, inclined-plane between 10 ° ~ 15 °, and fiting effect is good, is not easy to cause the wearing and tearing of side form land area, more is conducive to protect mould.
As better, be equipped with the moulding of wheel hub centre bore on the described upper die and lower die and insert.Adopt the technical program, can one-shot forming go out the wheel hub centre bore, the material that excises during later stage fine finishining is less, and economical with materials reduces cost, enhances productivity.
The closing precision that technique scheme has mainly improved mould improves, and has improved the mold use life-span, has effectively avoided having improved the precision of foundry goods because mould because designing the unreasonable Fast Wearing phenomenon of bringing, has reduced the quantity of hard edges and overlap.
