Specific embodiment
Core of the invention there is provided a kind of centrifugal casting metal die, improve its gas permeability, increased coating and does
Dry venting quality, improves the yield rate of casting.
Present invention also offers a kind of centrifugal casting system comprising the centrifugal casting metal die, centrifugal casting is improve
Yield rate.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-Fig. 2 is refer to, a kind of centrifugal casting metal die, including casting cylinder 1, casting is the embodiment of the invention provides
Multiple steam vents 2 are offered on the barrel of cylinder 1.In process of production, mould self-temperature is at 300 DEG C for centrifugal casting metal die
Left and right, after the water based paint of casting cylinder 1 inner chamber spraying 0.5-1.0mm, coating starts in the presence of the own temperature of cylinder 1 of casting
Dry and produce gas, in the presence of the centrifugal force of cylinder 1 of casting, along the discharge casting cylinder 1 of steam vent 2 inner chamber, coating is obtained gas
Sufficiently dry and be vented, in subsequent iron liquid casting cycle, coating surface does not have the influence of residual gas, and cast(ing) surface does not have
There are stomata, casting quality stabilization.
The centrifugal casting metal die improves gas permeability, makes what water based paint was produced in drying process in casting cylinder 1
Steam can be discharged from steam vent 2, increased the dry venting quality of coating, so as to reduce the stomata occurred in casting, be carried
The yield rate of casting high.
As shown in Fig. 2 in the present embodiment, steam vent 2 includes the outer section 22 and inner segment 21 of connection, the diameter of inner segment 21 is small
In outer section 22 of diameter, the outer section 22 barrel outside near casting cylinder 1 is set, and inner segment 21 sets near the barrel inner side of casting cylinder 1
Put.Diameter near the inner segment 21 of the inner chamber of casting cylinder 1 is smaller, can prevent coating from entering steam vent 2, near casting cylinder 1
Being relatively large in diameter for outside outer section 22, is conducive to gas quickly to discharge.
As optimization, in the present embodiment, outer section 22 of a diameter of 3mm~8mm, a diameter of 1mm of inner segment 21~
1.5mm.Size, ventilative degree with specific reference to casting cylinder 1 determine the diameter of steam vent 2.
In the present embodiment, the length of the inner segment 21 of steam vent 2 is 3mm~5mm, and the wall thickness of remaining casting cylinder 1 is
Outer section 22 of length.
In order that exhaust is uniform, in the present embodiment, steam vent 2 is uniformly distributed along the circumferencial direction of casting cylinder 1.So that
The exhaust velocity of each position of casting cylinder 1 is consistent, and the surface quality of continuous castings for obtaining is more uniform.
Further, in the present embodiment, on the circumferencial direction of casting cylinder 1, it has been evenly arranged 3 on same cross section~
8 steam vents 2.On the barrel of casting cylinder 1 a circle steam vent 2 is provided with multiple cross sections.Often the quantity of circle steam vent 2 is
3~8, and be evenly arranged.As often circle steam vent 2 quantity be 4, then on same circle, between two neighboring steam vent 2 between
Every angle be 90 °.Quantity as often enclosed steam vent 2 is 8, then on same circle, the interval angles between two neighboring steam vent 2
It is 45 °.Certainly, often circle steam vent 2 can also uneven distribution, simply exhaust effect be not so good as be evenly arranged it is good.
In the present embodiment, in the axial direction of casting cylinder 1, the spacing of the two neighboring steam vent 2 on same straight line is
60mm~90mm.I.e. in the axial direction of casting cylinder 1, multiple row steam vent 2, the two neighboring exhaust in each row steam vent 2 is distributed with
The spacing in hole 2 is 60mm~90mm.
As shown in figure 1, in the present embodiment, the setting interlaced with each other of steam vent 2 on two neighboring cross section.I.e. adjacent two
The circle along the circumferential direction setting interlaced with each other of steam vent 2.So as in the case of the identical casting size of cylinder 1, being arranged such to increase
Plus the density of steam vent 2, while ensureing the structural strength of casting cylinder 1.
Used as optimization, two spacing of adjacent vent hole 2 on two neighboring cross section are 30mm~60mm.I.e. adjacent
In the steam vents 2 of two circles, the exhaust adjacent with the correspondence that second encloses in steam vent 2 of each steam vent 2 in first lap steam vent 2
Spacing between hole 2 is 30mm~60mm.Depending on quantity of the specific size according to the casting size of cylinder 1 and steam vent 2.
Certainly, steam vent 2 can also use other arrangement forms, such as along the circumferential direction parallel multiple row exhaust being evenly arranged
Hole 2 etc., as long as exhaust can be played a part of, it is not limited to the arrangement form cited by the present embodiment.
Depending on the size and arrangement density of steam vent 2 are according to casting technique, water based paint moisture content is bigger, steam vent 2
Arrangement density is bigger, and the diameter of steam vent 2 is bigger；Casting length is more long, and casting section thickness is thinner, then the arrangement density of steam vent 2 is got over
Greatly, the diameter of steam vent 2 is bigger.
As shown in figure 3, based on the centrifugal casting metal die described by above example, the embodiment of the present invention is additionally provided
A kind of centrifugal casting system, including centrifugal casting metal die, baffle plate 4, flanging flyball 5, heat insulating mattress 6 and drive shaft 7.Its
In, centrifugal casting metal die is the centrifugal casting metal die described by any of the above embodiment, centrifugal casting metal die
Casting cylinder 1 be provided with opening end and sealing end；Baffle plate 4 is cyclic structure, and opening end is arranged on for stopping, after preventing cast
Iron liquid sputter to hurt sb.'s feelings from opening end；Flanging flyball 5 is arranged on opening end, for baffle plate 4 to be pressed on into opening end, prevents
Casting cylinder 1 unexpected the coming off of the baffle plate 4 in rotary course is hurted sb.'s feelings；Heat insulating mattress 6 be arranged on casting cylinder 1 sealing end and opening end it is interior
On side, the sealing end and baffle plate 4 of iron liquid directly contact casting cylinder 1, adhesion mould are prevented；Drive shaft 7 is connected with sealing end,
For driving casting cylinder 1 to rotate.
The centrifugal casting system employs the centrifugal casting metal die in the application, so as to improve gas permeability, makes water
The steam that base coating is produced in drying process in casting cylinder can be discharged from steam vent 2, increased the dry exhaust of coating
Property, so as to reduce the stomata occurred in casting, improve the yield rate of casting.
