Description
Technical field
The utility model relates to auto parts and components casting technology fields, and in particular to one kind flies for reducing automobile clutch
Take turns the mold of shrinkage defect.
Background technique
Known, coupling flywheel is one of the main component in automobile rotating mechanism, flywheel have appropriate rotary inertia,
Play the revolving member of storage and release kinetic energy, flywheel is mounted in the wheel having compared with large rotating inertia on machine rotating shaft
Shape accumulator, when machine rotational speed increases, the kinetic energy of flywheel increases, and energy storage or saving is got up；When machine rotational speed reduces, flywheel
Kinetic energy is reduced, and energy is released, and flywheel can be used to reduce the velocity perturbation of mechanical rotation process.Currently, clutch flies
Wheel mostly uses DISA vertical line tide film sand to cast, and the template size of its production line are as follows: long 650mm, width 530mm, Wheel casting
Size are as follows: diameter 280mm, high 50mm.Existing coupling flywheel is all made of the technological design that rising pouring adds top pouring；However, in length
It is found in the practical application of phase, due to be threadedly coupled with other parts, Wheel casting is typically designed all Wheel casting outer circle
It is very thick big, and the disk connecting with outer circle considers the condition of loss of weight and heat dissipation ventilation, so that all designs is partially thin, such wall
Thick difference great disparity it is too big, it is unsmooth to will result in Feeding channel in casting process, and Wheel casting outer circle is caused to go out with disk junction
Now a large amount of shrinkage defect, then providing a kind of mold for reducing automobile clutch flywheel shrinkage defect just seems especially heavy
It wants.
Summary of the invention
To overcome deficiency present in background technique, the utility model provides a kind of for reducing automobile clutch flywheel
The mold of shrinkage defect, the utility model artificially increase Feeding channel, realize riser by increasing voussoir on mold cavity
Molten metal in riser swimmingly can directly be added to by voussoir and need feeding by the bridge joint of neck and Shrinkage Porosity position
Position can effectively avoid the cast(ing) surface collapse defect generated in the too big process of setting of Wall-Thickness Difference.
To realize goal of the invention as described above, the utility model uses technical solution as described below:
It is a kind of for reducing the mold of automobile clutch flywheel shrinkage defect, including sprue cup, cross gate, die ontology,
Riser and voussoir, are equipped with sprue cup in the upper surface of the die ontology, cross gate are equipped in the lower section of sprue cup, in mold sheet
The middle part of body is equipped with type chamber, is equipped with riser in the top of the type chamber, and the upper end of the riser connects cross gate by sprue,
The lower end connecting-type chamber of riser is equipped with voussoir on the top of type chamber at riser, is equipped with ingate in the lower part of type chamber, described
Ingate connects cross gate by sprue and forms the mold for being used to reduce automobile clutch flywheel shrinkage defect.
The mold for being used to reduce automobile clutch flywheel shrinkage defect, the diameter of the riser are 30~50mm.
It is described for reducing the mold of automobile clutch flywheel shrinkage defect, the sectional area of the cross gate is 200~
300mm²。
The mold for being used to reduce automobile clutch flywheel shrinkage defect, the cross-sectional shape of the voussoir are right angle
Triangular structure.
It is described for reducing the mold of automobile clutch flywheel shrinkage defect, the sectional area of the sprue is 100~
200mm²。
Using technical solution as described above, the utility model has superiority as described below:
The utility model artificially increases Feeding channel, realizes riser neck and casting by increasing voussoir on mold cavity
Molten metal in riser swimmingly can directly be added to the position for needing feeding by the bridge joint at part shrinkage porosite position by voussoir,
The cast(ing) surface collapse defect generated in the too big process of setting of Wall-Thickness Difference can be effectively avoided, the utility model has structure letter
The features such as list, using effect is good, it is suitble to large-scale promotion and application.

Fig. 2 is the A-A schematic cross-sectional view of the utility model；
In figure: 1, sprue cup；2, cross gate；3, die ontology；4, riser；5, voussoir；6, ingate.
Specific embodiment
The utility model can be explained in more detail by the following examples, the utility model is not limited to following
Embodiment；
It is a kind of for reducing the mold of automobile clutch flywheel shrinkage defect, including sprue cup in conjunction with described in attached drawing 1~2
1, cross gate 2, die ontology 3, riser 4 and voussoir 5 are equipped with sprue cup 1 in the upper surface of the die ontology 3, in sprue cup 1
Lower section be equipped with cross gate 2, the middle part of die ontology 3 be equipped with type chamber, the top of the type chamber be equipped with riser 4, it is described to emit
The diameter of mouth 4 is 30~50mm, and the upper end of the riser 4 connects cross gate 2 by sprue, and the sectional area of the sprue is
100~200mm2, the sectional area of the cross gate 2 are 200~300mm2, the lower end connecting-type chamber of riser 4, on the top of type chamber
It is equipped with voussoir 5 at riser 4, artificially increases Feeding channel, realizes the bridge joint of riser neck and Shrinkage Porosity position, Neng Goutong
It crosses this voussoir 5 and the molten metal in riser 4 is swimmingly directly added to the position for needing feeding, it is enough effectively to avoid Wall-Thickness Difference
The cast(ing) surface collapse defect generated in too big process of setting, the cross-sectional shape of the voussoir 5 are triangular structure of right angle, root
