Abstract
The present invention relates to a kind of production methods of layback mould wheel hub, including coremaking step, step of overall modelling, lower core step, mould assembling step, casting step, and this invention simplifies operating procedures, have saved the production time, improve production efficiency.
Description
Technical field
The present invention relates to a kind of production methods of layback mould wheel hub, belong to the production method technical field of wheel hub.
Background technique
The production method of wheel hub at present, including coremaking step and step of overall modelling,
In coremaking step: being equipped with loose piece in core box, core sand is injected in core box, form sand core, manually take out sand after sand core molding
Core needs manually to beat the loose piece taken out in sand core, then loose piece is installed in core box, very the consuming time；
In step of overall modelling: by hub mold extrusion moulding chamber in sandbox, type chamber is vertically arranged molding sand, and the quantity of type chamber is 3；
Lower core step: after the completion of moulding, sand core being put into type chamber, then will be arrived inside sand core under heating sleeve.The life of wheel hub at present
Production method has the disadvantage in that 1, needs manually to beat the loose piece taken out in sand core, very the consuming time；2, step of overall modelling is formed
The quantity of type chamber is few, low efficiency；3, need to use heating sleeve in lower core step, it is cumbersome.
Summary of the invention
The technical problem to be solved by the present invention is to against the above deficiency, provide a kind of production method of layback mould wheel hub, letter
Change operating procedure, saved the production time, improves production efficiency.
In order to solve the above technical problems, the invention adopts the following technical scheme: a kind of production method of layback mould wheel hub, packet
Include coremaking step, step of overall modelling, lower core step, mould assembling step, casting step.
As a further improvement of the above technical scheme:
The coremaking step: core sand is injected in core box, is formed sand core, is manually taken out sand core after sand core molding.
The step of overall modelling: hub mold is installed on template frame, and the top box of sandbox is placed on template frame and type
Sheet frame cooperation, by molding sand filling sandbox top box in, molding sand in the top box of sandbox by hub mold extrusion moulding chamber, by mold
And template frame is separated with the top box of sandbox, the top box and type chamber of sandbox are passed away, and the type chamber quantity in the top box of sandbox is 4
It is a, 4 type chamber even level settings；Then the nowel of sandbox is placed on template frame again and is cooperated with template frame, repeated above-mentioned
Operation.
The lower core step: after the completion of moulding, sand core is put into the type chamber of nowel.
The mould assembling step: top box and the nowel after lower core are assembled together.
The casting step: will be poured onto type chamber after molten iron deslagging, and molten iron temperature is controlled in 1360-1395 degree.
A kind of production method of layback mould wheel hub, further includes cooling step: it is small that the sandbox after casting is put room temperature cooling about 2
When.
A kind of production method of layback mould wheel hub further includes cleanup step of unpacking: casting is formed after molten iron is cooling, by casting
The sand and burr on surface remove, and remove riser flow path, and the hanging chain of casting is cooling, then carry out Shot Blasting to casting.
After the invention adopts the above technical scheme, compared with prior art, have the advantage that
1, reduce the step of taking loose piece in coremaking step, save the production time；
2, the quantity of step of overall modelling shape forming cavity is more, improves production efficiency；
3, operating procedure is simplified without using heating sleeve in lower core step.
The following describes the present invention in detail with reference to examples.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now illustrate of the invention specific
Embodiment.
Embodiment, a kind of production method of layback mould wheel hub include the following steps: coremaking step, step of overall modelling, lower core step
Suddenly, mould assembling step, casting step, cooling step, cleanup step of unpacking；
Coremaking step: core sand is injected in core box, is formed sand core, is manually taken out sand core after sand core molding；
Step of overall modelling: hub mold is installed on template frame, and the top box of sandbox is placed on template frame and is cooperated with template frame,
By molding sand filling sandbox top box in, molding sand in the top box of sandbox by hub mold extrusion moulding chamber, by mold and template frame
It is separated with the top box of sandbox, the top box and type chamber of sandbox are passed away, and the type chamber quantity in the top box of sandbox is 4,4 types
Chamber even level setting；Then the nowel of sandbox is placed on template frame again and is cooperated with template frame, repeat aforesaid operations；
Lower core step: after the completion of moulding, sand core being put into the type chamber of nowel, the first step, inspection type chamber, sand core, and confirmation is complete
Without breakage, sand core is put into inside type chamber by second step；
Mould assembling step: top box and the nowel after lower core are assembled together；
Casting step: will be poured onto after molten iron deslagging in type chamber: by molten iron be put into subcontract interior thermometric, slagging-off, temperature, which controls, to exist
1360-1395 degree is then aligned with cast gate casting, molten iron is poured onto type chamber；
Cooling step: it is about 2 hours cooling that the sandbox after casting is put into room temperature；
Unpacking cleanup step: forming casting after molten iron is cooling, the sand of cast(ing) surface and burr removed, riser flow path is removed,
The hanging chain of casting is cooling, Shot Blasting then is carried out to casting, if the sand of cast(ing) surface and burr are also not after ball blast
It removes completely, then secondary Shot Blasting is carried out to casting.
The above specific embodiments are only exemplary, is to enable those skilled in the art to better understand this
Summary of the invention should not be construed as limiting the scope of protection of the present invention, as long as changing made by technical solution according to the present invention
Into each falling within protection scope of the present invention.
