Description
Technical field
The present invention relates to a kind of casting method, especially a kind of casting mould for solving pressure shell internal porosity belongs to metal
Casting technology field.
Background technology
The pressure shell of turbocharger conventional structure using conventional casting techniques can realize inside pressure shell without shrinkage porosite cast, because
This can suppress the requirement leaked hunting completely substantially.But with continuing to develop for technology for Turbocharger Manufacturing, occur in that some special knots
The pressure shell (such as intermediate position is thick big and isolates relatively, and casting section thickness is thicker) of structure, actually shows that such pressure shell passes through biography
Internal and tube wall shrinkage porosite can not be completely eliminated in the casting technique of system, because under the conditions of conventional casting techniques, such pressure shell is filling
Type and process of setting medium casting internal structure it is thick it is big, need that the distance of feeding is longer, Feeding channel is past during riser feeding
Toward being solidified prior to casting center Hou great positions, as a result rising head can not effectively play its feeding work(to casting center Hou great positions
Can, cause casting center Hou great positions to produce shrinkage defect, have a strong impact on casting quality.
The content of the invention
It is an object of the invention to：In view of the above-mentioned problems of the prior art, improved by structure, propose that one kind can be with
The casting mould of pressure shell internal porosity is properly settled, so as to ensure the castability of the thick big pressure shell of internal structure.
In order to reach object above, the casting mould of solution pressure shell internal porosity of the invention includes having required inner
The scroll casing shape pressure shell main body mould of chamber, the outside of the pressure shell main body mould has the vertical running channel of upper end open, the vertical running channel
Connected respectively with two towards the ingate of pressure shell main body mould by the horizontal running channel that extends towards both sides；The ingate is by upward
Connected after the inlet side rising head of opening with the radial inlet of pressure shell main body mould, be provided between two radial inlets and be located at pressure shell main body mould circle
(" chill " is that casting industry is used for the professional term of Quench to profile-followed chill, and its material can be any gold at the two of disk upper surface
Category, the even higher composite of the heat storage coefficient such as graphite)；The side of the pressure shell main body mould away from vertical running channel is provided with through contracting
The exothermic riser that neck extends upward, it is cold provided with arc between the necking down of the exothermic riser and pressure shell main body mould disk upper surface
Iron.
The present invention is further improved, geometry modulus (volume/radiating of geometry modulus=casting of the exothermic riser
Surface area) with needing the ratio between feeding position modulus to be 1.2 ± 0.1 inside pressure shell:1 (best 1.2:1).
The present invention is further improved, and the thickness of the arc chill is the 1/2-1/4 of exothermic riser recess diameter
(best 1/3).
The present invention is further improved, and the geometry modulus of the inlet side rising head inside pressure shell with needing feeding position mould
The ratio between number is 1.2 ± 0.1:1 (best 1.2:1).
The present invention according to ingenious reasonable setting due to including the casting of sprue, cross gate, ingate and multiple rising heads
Structure, exothermic riser therein can effectively extend the time of riser neck position molten steel solidification, and feeding is carried out to pressure shell inside, from
And the shrinkage porosite inside pressure shell is eliminated, and be arranged at optimal Feeding channel, it can be ensured that rising head big position thick to cast-internal is entered
The maximum feeding of row；The arc chill being appropriately arranged with can both prevent because the thermal center of riser neck it is excessive caused by casting table
Reduction of area pine, while it also avoid because of the oversized feeding effect for causing riser neck to solidify influence exothermic riser in advance；Two are entered
Rising head is held to be used to feeding casting tube wall, and the profile-followed chill of two blocks be arranged between can then shorten Feeding channel, prevent pressure shell pipe
Shrinkage porosite, which occurs, in wall causes casting gas leakage.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is Fig. 1 upward view.
Fig. 3 is Fig. 1 stereogram.
Embodiment
Embodiment one
The present embodiment solves the casting mould of pressure shell internal porosity as shown in Figure 1, 2, 3, the pressure with required internal die cavity
Shell main body mould 9 is in scroll casing shape, and outside of the pressure shell main body mould 9 away from volute outlet has the vertical running channel 1 of upper end open, and this is vertical
Running channel 1 is connected with two towards the ingate 4 of pressure shell main body mould 9 respectively by the horizontal running channel 3 that extends towards both sides.Vertical running channel 1
Through filter block 2 between horizontal running channel 3.Two ingates 4 respectively through after upwardly opening inlet side rising head 5,11 with pressure shell main body
The radial inlet connection of mould 9.The angle of two radial inlets is 120 °, each other provided with respectively positioned at the disk of pressure shell main body mould 9
The profile-followed chill 8,10 of upper surface arcuation at cylindrical two.The geometry modulus of inlet side rising head 5 inside pressure shell with needing feeding position
It is 1.2 to locate the ratio between modulus.Side of the pressure shell main body mould 9 away from vertical running channel 1 is provided with the exothermic riser 6 extended upward through necking down,
The geometry modulus of exothermic riser 6 is with needing the ratio between feeding position modulus to be 1.2 inside pressure shell.The necking down of exothermic riser 1 and pressure shell
The arc chill 7 close to one of profile-followed chill 8 is provided between the disk upper surface of main body mould 9, the thickness of the arc chill 7 is heating
The 1/3 of the recess diameter of rising head 6.
The present embodiment in pressure shell middle circle card due to according to casting structure, being rationally provided with exothermic riser, its position
Just locating at optimal Feeding channel, it is hereby ensured that carry out maximum feeding to the thick big position of cast-internal；Exist simultaneously
Exothermic riser neck sets arc chill with pressure shell disk upper surface, can both prevent from causing on casting because the thermal center of riser neck is excessive
Surface shrinkage porosite, can prevent from causing riser neck to solidify influence feeding in advance because chill is oversized again；In addition, setting two inlet sides
Rising head can be with feeding casting tube wall, and the profile-followed chill between two rising heads prevents pressure shell tube wall from occurring then to shorten Feeding channel
Shrinkage porosite causes casting gas leakage.
Practice have shown that, using the process structure of the present embodiment, it can effectively solve the thick big portion in inside of special construction pressure shell
Quality requirement is fully achieved without obvious shrinkage defect in the shrinkage porosite problem that position and tube wall are produced, the pressure shell cast-internal of production.
In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
