Description
Technical field
The present invention relates to high vacuum casting technology field, specially a kind of composite exhaust plate for high vacuum casting mould
Structure.
Background technique
Mold is modern industry, especially the essential technique of the industry such as automobile, radio, aviation, instrument, daily necessities
Equipment.With the demand of automotive light weight technology, traditional press casting procedure is not able to satisfy increasingly in the remaining stomata problem of cast-internal
Requirement of the auto vendor to product comprehensive performance.
It is increasingly prominent for the demand of steel with aluminium, from traditional cylinder body, cylinder cover, case of transmission and clutch housing,
The automobile structures product such as damping tower, subframe and engine crossbeam by now suffers from full aluminium alloy compression casting market.Aluminium
Alloy automobile structural member is also much higher than conventional aluminum castings desire to the performance requirement of aluminium casting, and the hole inside traditional die casting is asked
Topic, need to be strictly controlled in structural member field, and just can be carried out heat treatment improves casting character.Therefore, on traditional die casting basis
On, there are more vacuum casting process to attempt, there are more adjustment in mold, equipment and technique.How as far as possible
Enhance the leakproofness of entire casting system, reduces the air pressure in the intracavitary portion of vacuum type as far as possible, prevent the volume of cavity filling process
Gas problem becomes the key subjects in industry.
Summary of the invention
In view of this, the present invention is directed to propose a kind of hardened structure of composite exhaust for high vacuum casting mould, Neng Gouxian
Writing improves exhaust effect and the intracavitary vacuum degree of raising type, alleviates a possibility that aluminium alloy enters vacuum line, reduces casting
Interior porosity improves product qualification rate.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of hardened structure of composite exhaust for high vacuum casting mould, including cover half exhaustion plate, moving die exhaust plate, the cover half
Cover half exhaust block, moving die exhaust block are provided between exhaustion plate and the moving die exhaust plate.
The cover half exhaust block and the moving die exhaust block, which use, has high thermal conductivity material, is selected by reasonable material
With and structure design, on the basis of saving spare parts cost, be integrated on conventional exhaust plate material high thermal conductivity energy row
Gas material block ensure that molten aluminum energy fast cooling is cooling, increase die venting sectional area, reduce bleb content.
The cover half exhaust block and the moving die exhaust block use material for tungsten-molybdenum alloy, and the heat conductivity of tungsten-molybdenum alloy is
3-5 times of traditional heat resisting steel significantly increases rate of heat dispation of the aluminium alloy on exhaustion plate.
Exhaust clearance is equipped between the cover half exhaustion plate and the moving die exhaust plate, the exhaust clearance is 1.0~1.5m
M, the exhaust sheet separation than common homogenous material obviously increase, and will not give a tongue-lashing aluminium blocking vacuum line problem, significantly enhance
Exhaust effect, mold vacuum degree can be effectively controlled within 5kpa.
The exhaust clearance wavy setting between the cover half exhaustion plate and the moving die exhaust plate, waveform exhaust
Gap can dramatically increase heat dissipation area.
It is provided with installation card slot on the cover half exhaustion plate and/or the moving die exhaust plate, is played when installing exhaust block
Positioning uses.
The moving die exhaust plate upper end setting it is fluted, convenient for operator with tool by exhaustion plate from it is framed it is interior pluck out,
Alleviate the labor intensity of mold repair.
The cover half exhaustion plate and the moving die exhaust plate basis material are copper alloy or hot die steel.
Hot die steel refers to the alloy tool steel for being suitable for making the mold that thermal deformation processing is carried out to metal, such as heat
Forging die, hot extruding die, compression mod, hot upsetting mould etc..It works since hot-work die is under high-temperature and high-pressure conditions for a long time,
It is required that mold materials have high intensity, hardness and thermal stability, should especially there are high heat-intensity, thermal fatigue, toughness and resistance to
Mill property.
Compared with the existing technology, the composite exhaust hardened structure of the present invention for high vacuum casting mould has following
Advantage:
Composite exhaust hardened structure of the present invention for high vacuum casting mould, the low cost designed using wavy shaped configuration
Active and inactive mold exhaustion plate matrix is integrated with the active and inactive mold exhaust block of high thermal conductivity, effectively enhances molten aluminum on active and inactive mold exhaustion plate
Solidification rate, it is therefore prevented that molten aluminum overflow blocks vacuum line, while between active and inactive mold exhaustion plate gap can increase to 1.0 ~
1.5mm significantly increases exhaust passage sectional area, and gas can quickly huge discharge be discharged, thus reduce interiors of products stomata,
Improve product qualification rate.
