Description
Technical field
The present invention relates to auto parts and components manufacture field, more particularly, to a kind of wheel hub casting mould positioning clamping.
Background technology
Currently, how by the way of casting, automotive hub to be manufactured.The casting technique of automotive hub mainly adopts whole
Body cast type.The technique of one piece casting wheel hub is that liquid alloy is added casting mould, and liquid alloy cools down in casting mould
Coagulation forming, after the wheel hub blank in casting mould is taken out, can get finished product wheel hub through polish such as polishings.Casting mould
Including upper die and lower die, upper die and lower die mutually fasten, so that liquid alloy forms predetermined form.In casting process, need
Guarantee that the faying face of upper die and lower die is capable of sealing.Currently, mainly make upper mould tight by the way of to upper mould press perpendicular
Detain mould, to realize the sealing of the faying face of upper die and lower die.However, such sealing means effect on driving birds is not good, overlap situation is tight
Weight.
Content of the invention
The purpose of the present invention is the problems referred to above overcoming prior art, provides a kind of wheel hub casting mould locating clip tight knot
Structure.
The purpose of the present invention is achieved through the following technical solutions：
Wheel hub casting mould positioning clamping, including mould under mould on the wheel hub cooperating and wheel hub；
On described wheel hub, the outer peripheral face of mould is provided with multiple upper fixed blocks；Under described wheel hub the outer peripheral face of mould be provided with multiple lower solid
Determine block；Upper tapped through hole is offered on fixed piece；Lower tapped through hole is offered on described lower fixed block；Described upper screw thread
Through hole is coaxial with described lower tapped through hole, and described upper tapped through hole is identical with described lower tapped through hole diameter；Fixed piece
Lower surface be close to the upper surface of described lower fixed block；The female thread of described upper tapped through hole and the interior spiral shell of described lower tapped through hole
Stricture of vagina is collectively forming continuous screw thread；
Also include threaded post；Described threaded post is coordinated with described upper tapped through hole and described lower tapped through hole screw thread simultaneously；Described
The cooling through hole prolonging the extension of its axis is opened up in threaded post；The edge of the described upper end end face stating threaded post is provided with annular protrusion.
Inventor finds through research, and why in wheel hub casting process, finning is serious, is due to hanging down to upper mould
During straight pressurization, due to the effect of mould inside pressure, upper die and lower die can be led to produce micro relative slip in the horizontal plane,
The gap that slip produces leads to finning to occur.For this reason, inventor providing the present invention.The present invention in the course of the work, spiral shell
Stricture of vagina post coordinates so that in casting process simultaneously with upper tapped through hole and lower tapped through hole screw thread, and under mould and wheel hub on wheel hub, mould is not
Can occurred level face relative movement, the occurrence of effectively reduce overlap.Meanwhile, threaded compared to hole axle cooperation,
Its precision is higher, it can be avoided that the slight clearance being difficult to avoid that during hole axle cooperation, can avoid mould on wheel hub to the full extent
And the horizontal displacement between mould under wheel hub.Because casting process temperature is higher, threaded post is heated generation micro-deformation, will lead to take off
During mould, threaded post is difficult to take out.If waiting threaded post to be drawn off again after cooling down completely, the wheel hub blank demoulding can be led to difficult, and
Extend the production time.It is also provided with for this cooling down through hole, after wheel hub cooling shaping, annular is stretched in the end of cooling water pipe
In projection, cooling water is made to pass through to cool down through hole, thus lowering the temperature to threaded post, so that threaded post can be taken easily and in time
Go out.Annular protrusion can be to its barrier effect of cooling water, it is to avoid cooling water overflows.
Further, described cooling through hole is multiple, and multiple described cooling through holes are equal around the axis of described threaded post
Even arrangement.
Setting multiple cooling through holes so that threaded post can obtain faster and evenly cooling, be favorably improved
The service life of threaded post.
Further, the inner peripheral surface of described annular protrusion is provided with insulating layer of asbestos.
Setting insulating layer of asbestos, it is to avoid the end of cooling water pipe is impaired at high temperature when cooling down threaded post.
Further, the taper surface that the inner peripheral surface of described annular protrusion is gradually reduced from top to bottom for diameter.
The taper surface that the inner peripheral surface of annular protrusion is gradually reduced from top to bottom for diameter, from can preferably and cooling water
The end cooperation of pipe, avoids cooling water to overflow further.
Further, fixed piece of lower surface is provided with locating dowel；The upper surface of described lower fixed block is provided with
Location hole；Described locating dowel is inserted in described location hole；The diameter of described locating dowel is less than the diameter of described location hole.
Setting locating dowel and location hole, it is just right to contribute to upper tapped through hole and lower tapped through hole in matched moulds, improves matched moulds
When operating efficiency.
The invention has the advantages that：
1. in the course of the work, threaded post is coordinated so that casting with upper tapped through hole and lower tapped through hole screw thread the present invention simultaneously
During, under mould and wheel hub on wheel hub mould will not occurred level face relative movement, the occurrence of effectively reduce overlap.With
When, it is threaded that compared to hole axle cooperation, its precision is higher, it can be avoided that the slight clearance being difficult to avoid that during hole axle cooperation, energy
Enough avoid the horizontal displacement between mould under mould and wheel hub on wheel hub to the full extent.Because casting process temperature is higher, screw thread
Post is heated generation micro-deformation, and threaded post during the demoulding will be led to be difficult to take out.If waiting threaded post to be taken again after cooling down completely
Go out, the wheel hub blank demoulding can be led to difficult, and extend the production time.It is also provided with for this cooling down through hole, be cooled in wheel hub
After type, the end of cooling water pipe is stretched in annular protrusion, make cooling water pass through to cool down through hole, thus lowering the temperature to threaded post, with
Threaded post is enable to be removed easily and in time.Annular protrusion can be to its barrier effect of cooling water, it is to avoid cooling water overflows.
2. setting multiple cooling through holes so that threaded post can obtain faster and evenly cooling, contribute to carrying
The service life of high threaded post.
3. insulating layer of asbestos is set, it is to avoid when cooling down threaded post, the end of cooling water pipe is impaired at high temperature.
4. the taper surface that the inner peripheral surface of annular protrusion is gradually reduced from top to bottom for diameter, from can preferably with cool down
The end cooperation of water pipe, avoids cooling water to overflow further.
5. setting locating dowel and location hole, it is just right to contribute to upper tapped through hole and lower tapped through hole in matched moulds, improves and closes
Operating efficiency during mould.
