Abstract
The invention discloses a kind of injection molding machine wallboard cast bar gate type sprue cups.Bar gate type sprue cup in the present invention does not exist together as follows with common sprue cup：1, increase flashboard, be used for pushing off the slag, pure molten metal is made to flow into down gate from bottom；2, increase well, avoid high-temperature liquid metal wrapped folder gas or sundries is directly entered running channel, the impact of running channel is washed away in mitigation, avoids turbulent flow, prevents molten metal splashing, oxidation from forming secondary oxidation slag inclusion, while pushing off the slag.
Description
Technical field
The invention belongs to casting industry fields, and in particular to a kind of injection molding machine wallboard cast bar gate type sprue cup, cast
When, effect is to accept the molten metal from casting ladle, prevents from splashing and overflow, facilitates cast, and high-temperature liquid metal introducing is directly poured
Road.
Background technology
Current client is more and more tighter to the dimensional accuracy and appearance requirement of injection molding machine casting：Casting dimension accuracy requirement
Exceed the professional standard of GB/T6414 already, surface roughness requirements are also so under overall situation beyond GB/T 6060.1
Casting high quality, high-precision machine tool parts, from casting Technology Design and casting process cast optimization, to improve casting accuracy
With surface quality, it is considered as pushing off the slag and the reduction high-temperature liquid metal Secondary Oxidizing Slag problem of sprue cup first.
Invention content
Goal of the invention：In order to solve the deficiencies in the prior art, the present invention provides a kind of injection molding machine wallboard cast gates
Formula sprue cup.
Technical solution：A kind of injection molding machine wallboard cast bar gate type sprue cup, including sandbox, resin bonded sand mould, flashboard, directly pour
Handle is hung in road and lifting, and the sandbox external symmetry is equipped with lifting and hangs handle, places sprue cup template mold in the sandbox, then use
Resin sand back-up sand forms resin bonded sand mould, and the molding after resin bonded sand mould solidification uses the preceding zircon flour coating for brushing at least 2 times and baking
It is dry；The flashboard is made of resin sand, and at least 2 times zircon flour coatings are brushed before installation and are dried；The sprue is according to work
Skill needs the ceramic tube using different size.
As an optimization：The size of the sandbox, according to our factory's actual process needs, makes 3-5 with steel plate thickness used
Handle is hung in specification, then installation.
As an optimization：The template mold that the sprue cup is needed to be fabricated to different model size by technique, after placing sandbox,
With resin sand back-up sand, mold thickness is between 50-100mm.
Advantageous effect：Bar gate type sprue cup in the present invention does not exist together as follows with common sprue cup：1, increase flashboard, be used for
Pushing off the slag makes pure molten metal flow into down gate from bottom；2, increase well, avoid high-temperature liquid metal wrapped folder gas or miscellaneous
Object is directly entered running channel, and the impact of running channel is washed away in mitigation, avoids turbulent flow, prevents molten metal splashing, oxidation from forming secondary oxidation
Slag inclusion, while pushing off the slag.
Its feature is described as follows：
1, mainly for high-precision machine tool part, large and medium-sized casting and design.
2, when high-temperature liquid metal pours into sprue cup, well plays buffering, while high-temperature liquid metal pours here
It turns over and gushes, carry out secondary oxidation and give birth to slag, reduce the two secondary slags in cavity, reduce the surface gas cinder hole of casting, keep cast structure pure
It is net fine and close.
3, small using slag ratio molten metal density and be suspended in the principle on molten metal surface, slag inclusion layer is formed, collects slag and blocking
Shape, flashboard play the role of pushing off the slag.
4, the gap of flashboard and well bottom surface, the flow velocity of controllable preparing metal liquid and the duration of pouring are adjusted, molten metal is made to exist
Laminar flow is formed in running channel, it is more stable to fill type, no rolling.Avoid security risk caused by high-temperature liquid metal splash simultaneously.
5, advantage：Pushing off the slag keeps away slag, reduces Secondary Oxidizing Slag, coutroi velocity, and guarantee fills that type is steady, reduces high-temperature liquid metal
It splashes, it is ensured that pure iron liquid enters cavity, produces the casting of high quality.And peace caused by avoiding molten metal splashing from overflowing
Full accident.

Specific implementation mode
Embodiment
A kind of cast of injection molding machine wallboard bar gate type sprue cup, including sandbox 1, resin bonded sand mould 2, flashboard 3,4 and of sprue
It hangs 5,1 external symmetry of the sandbox is equipped with lifting and hangs 5, and the sandbox 1 is interior to place sprue cup template mold, then uses
Resin sand back-up sand forms resin bonded sand mould 2, the molding after the solidification of resin bonded sand mould 2, simultaneously using the preceding zircon flour coating for brushing at least 2 times
Drying；The flashboard 3 is made of resin sand, and at least 2 times zircon flour coatings are brushed before installation and are dried；The sprue 4
The ceramic tube using different size is needed according to technique.
The size of the sandbox 1, according to our factory's actual process needs, makes 3-5 specification, then with steel plate thickness used
Installation is hung 5.
The template mold that the sprue cup is needed to be fabricated to different model size by technique uses resin sand after placing sandbox
Back-up sand, mold thickness is between 50-100mm.
Bar gate type sprue cup in the present invention does not exist together as follows with common sprue cup：1, increase flashboard, be used for pushing off the slag, make pure
Net molten metal flows into down gate from bottom；2, increase well, avoid high-temperature liquid metal wrapped folder gas or sundries directly into
Enter running channel, the impact of running channel is washed away in mitigation, avoids turbulent flow, prevents molten metal splashing, oxidation from forming secondary oxidation slag inclusion, simultaneously
Pushing off the slag.
Its feature is described as follows：
1, mainly for high-precision machine tool part, large and medium-sized casting and design.
2, when high-temperature liquid metal pours into sprue cup, well plays buffering, while high-temperature liquid metal pours here
It turns over and gushes, carry out secondary oxidation and give birth to slag, reduce the two secondary slags in cavity, reduce the surface gas cinder hole of casting, keep cast structure pure
