Description
Technical field
The utility model relates to carbon fiber rim field shaping technique, refers in particular to a kind of mould of carbon fiber rim.
Background technology
In prior art, wheel rim is generally the cast of aluminium alloy one or die cast, and the mould of its use is formed by the side form piece and the upper and lower die combination that are no less than 2.Patrix arranges sprue gate or die casting mouth, and aluminum alloy melt cast or the die casting of molten condition are entered in mould.The cooling rear demoulding, then forms through finishing.Aluminium alloy wheel rim has good heat dissipation, lightweight, precision high.
But aluminium alloy wheel rim weight is still larger, intensity and rigidity are all not enough.And carbon fibre composite wheel rim has higher intensity and higher, the higher rigidity of security and handling better, lower thermal coefficient of expansion, weight be lighter and save power, less rotary inertia and acceleration is better, good impact resistance, thermal capacity are little and the anticorrosive advantage such as strong.
But the process of moulding carbon fibre composite wheel rim and the process of moulding aluminium alloy wheel rim are distinct.While making carbon fiber cavity-like or tubular products in industry, generally all can adopt expanded material or inflatable airbag provide in goods inner side pressure by goods compacting on mold inside, moulding is then heating and curing.
For carbon fiber rim, spoke and wheel mounting disc position stressing conditions are comparatively complicated, be subject to the ringing of tension, compression, torsion, shearing force, and these position institutional frameworks must be solid reliable simultaneously.So it is infeasible only simply using airbag moulding when moulding spoke and mounting disc position.One, airbag material is too soft, and the mounting disc inner surface that cannot precise forming goes out to have fitted position required precision and flatness to require, cannot reach the matching requirements of wheel.The two, airbag material is too soft, cannot be by spoke and wheel rim body junction, spoke itself, spoke and mounting disc junction, these stressing conditions complexity of mounting disc itself, complex-shaped position compacting, interior tissue cannot be solid evenly, shape cannot full symmetric, unification, make the institutional framework of internal carbon fibers and resin occur the situations such as loose, pore, gum deposit, starved, do not reach requirement of strength; And weight is at these position skewness, affects the dynamic balancing of wheel rim, affect vehicle stability, handling, make tire wear inhomogeneous, there is potential safety hazard.

Three, the side form of at least two is closed up successively, surround carbon fiber rim blank lateral surface;
Four, interior benevolence is put into carbon fiber rim blank body, patrix is arranged on side form top;
Five, whole mould is put into forming bench, compress upper die and lower die and side form, moulding is heating and curing.
Further, described carbon fiber rim blank is formed by following steps:
One, carbon fibre composite is successively coiled into cylindric by different machine directions, form wheel rim body blank;
Two, carbon fibre composite is become to the ring-type of the second wheel rim by different machine direction layings, form wheel rim the second wheel rim blank;
Three, carbon fibre composite is become to the blank of spoke and wheel mounting disc by different machine direction layings;
Four, by wheel rim body blank, the second wheel rim blank, spoke and the assembly of wheel mounting disc blank, laying reinforcement is carried out with carbon fibre composite respectively again in inner side and outside in blank and blank junction, winding reinforcing, is finally coated in inner face and the outside of integral workblank with large stretch of carbon fibre composite cloth, forms the one-body molded blank that comprises wheel rim body, the first wheel rim, the second wheel rim, spoke and wheel mounting disc.
Adopt after such scheme, the one-body molded carbon fiber rim that uses the utility model mould and forming method to manufacture, has the following advantages:
One, moulding wheel mounting disc fitting surface flatness is better, and fitted position precision is higher, and meanwhile, product integral installation precision is higher.
Two, make spoke and wheel rim body junction, spoke itself, spoke and wheel mounting disc junction, wheel mounting disc described position compacting itself, interior tissue is solid evenly, shape is symmetrical.
Three, make the positions such as spoke and wheel rim body junction, spoke itself, spoke and wheel mounting disc junction, wheel mounting disc itself no longer occur the situations such as institutional framework is loose, pore, gum deposit, starved.
Four, make weight distribute comparatively even at spoke and wheel rim body junction, spoke itself, spoke and wheel mounting disc junction, wheel mounting disc itself.
Five, not additional heating device of mould itself without pullling power line or thermal source pipeline, facilitates workman to operate in the time putting into blank, die sinking, matched moulds, evades workman's maloperation and the hidden danger that is electrically shocked or is burned, improves processing safety.
Six, the not additional heating pipe line of mould itself and heater, save manufacturing cost, dwindles mould volume, reduces the thermal capacity of whole mould, in the time of heating cool cycles each time, reduces energy consumption, cost-saving.
Seven, on same heat cure forming bench successively circulating-heating two overlap or two covers with mold, board can, always in heated condition, needn't be waited for the time of mold cools down, improves board utilization rate, enhances productivity, and saves time, cost-saving.
