Abstract
The present invention relates to wheel hub machine casting processing mold field, specially a kind of wheel hub casting mould, including hub body, pouring and riser systemses and core part, the upper end of hub centre connects a rising head by riser neck, riser neck is back taper, heat affecting block is provided with the lower end of rising head, position with spoke is corresponding, wheel hub is while provided with core, to reduce the size of riser neck and form heat affecting block, the quantity of described heat affecting block is corresponding with the quantity of spoke, the setting of core, reduce the size of riser neck, just rising head can be removed using hand hammer, substantially reduce the cost of remove feeders；Heat affecting block, can delay the solidification for connecting spoke to be later than the setting time of outer ring and disc junction, it is ensured that outer ring is up-to-standard；The volume of heat affecting block is about 20% that rising head volume is set in surrounding, and this improves the utilization rate of molten iron；Simple in construction, small volume adds the quantity of each mould production, 50% can be put per type, production efficiency is improved more.
Description
Technical field
The present invention relates to wheel hub casting processing mold field, specially a kind of wheel hub casting mould.
Background technology
Hub mold is the important process equipment for casting hub, and such wheel hub part material is spheroidal graphite cast-iron, structure
For inside and outside two parts, connected by middle relatively thin disc.Handed over during Foundry Production in thick middle major part and outer ring with disc
The place of connecing is internal easily to there is the empty class defect of shrinkage cavity and porosity.In order to ensure the most inherent quality of wheel hub thick middle, typically exist
The big position top of thick middle sets rising head to carry out feeding；In order to ensure outer ring and disc junction internal soundness, typically in former
Outside with outer ring junction sets rising head.Using original mould, removing middle rising head need to use lathe to cut off removal, efficiency
It is low, it is costly；And because periphery sets rising head, rising head will be set in each disc junction, the utilization rate of molten iron is relatively low,
Outside sets rising head occupancy template area larger, and the quantity of each mould production is reduced during production, reduces production efficiency, final warp
Index of helping is poor.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of simple in construction, small volume, economizing on resources, improving work
Make the wheel hub casting mould of efficiency.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of wheel hub casting mould, including hub body, pouring and riser systemses and core part, the upper end of hub centre passes through riser neck
A rising head is connected, riser neck is that heat affecting block is provided with back taper, the lower end of rising head, between hub centre and outer ring, with wheel
The position of spoke is corresponding；Wheel hub is while provided with core, to reduce the size of riser neck and form heat affecting block.
A kind of above-mentioned wheel hub casting mould, the quantity of described heat affecting block is corresponding with the quantity of spoke.
A kind of wheel hub casting mould of the present invention, compared with prior art, its advantage is：The core of design, can
To reduce the size of riser neck, just rising head can be removed using hand hammer, solve the trouble removed using lathe, substantially reduce production
Cost；Heat affecting block is set at spoke, when can delay the solidification for connecting spoke to be later than the solidification of outer ring and disc junction
Between, it is ensured that outer ring is up-to-standard；Meanwhile, the volume of heat affecting block is about rising head volume is set in surrounding 20%, and this improves iron
The utilization rate of water；It is simple in construction, small volume, every occupancy mould area reduce, which increase each mould production quantity, often
Type can put 50% more, and production efficiency is improved.
Use principle：Molten iron is full of whole die cavity, molten iron cooled and solidified by ingate by rising head.The big portion of casting thick middle
Divide and acted on by the riser feeding on top, it is ensured that quality is intact herein.By setting heat affecting block, make disc setting time
Delay, is later than junction solidification, the contraction of the most molten iron supplement junction solidification of thick middle, it is ensured that disc joins with outer ring
Place occurs without shrinkage cavity defect, it is ensured that quality is intact at this.Whole design makes center section heat concentration, solidifies later, does not influence
Casting radiates and rapid solidification to surrounding, meets heat transfer principle.
Brief description of the drawings
Accompanying drawing 1 does not carry the dimensional structure diagram of core for invention；
Accompanying drawing 2 is Fig. 1 overlooking the structure diagrams of the present invention；
Accompanying drawing 3 carries the cross section structure diagram of core for the present invention.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the upper end of hub centre connects a rising head 2 by riser neck 5, and riser neck 5 is back taper
Heat affecting block 4a, 4b, 4c are provided with shape, the lower end of rising head 2, it is relative with the position of spoke 3 between hub centre and outer ring 1
Should, wheel hub is while provided with core 6, to reduce 5 sizes of riser neck and form heat affecting block 4a, 4b, 4c, the setting of core 6 can
To reduce the size of riser neck 5, just rising head can be removed using hand hammer, solve the trouble removed using lathe, substantially reduce life
Produce cost；Heat affecting block 4a, 4b, 4c are set at spoke 3, the solidification for connecting spoke can be delayed to be later than outer ring and be connected with disc
The setting time at place, it is ensured that outer ring is up-to-standard；During work, molten iron initially enters rising head 2, then enters wheel by rising head 2
Hub die cavity and heat affecting block 4a, 4b, 4c, because rising head 2 and heat affecting block 4a, 4b, 4c concentrate on the central area of product, radiating
Condition is poor, solidifies slower, therefore the ability enhancing of feeding molten iron, the influence that heat affecting block is cooled down to spoke 3 so that spoke 3
It is later than outer ring solidification, so can ensures the complete of hub cast with the molten iron of smaller size smaller,
For those skilled in the art, technical scheme that can be as described above and design, make other various phases
The change and deformation answered, and all these change and deformation should all belong to the claims in the present invention protection domain it
It is interior.
