Description
Technical field
The invention belongs to counter-gravity casting equipment fields, and in particular to a kind of sealing of antigravity casting ceramic lift tube
Fixed structure.
Background technique
In antigravity casting, either low pressure casting, counter-pressure casting, suction pouring, current major part are all applied lower
In the non-ferrous metals casting of fusing point, it is common to use T-type ceramic lift tube, the i.e. ceramic lift tube of flange plate.It is producing in batches
In the process, ceramic lift tube is immersed in molten metal always, is needed to be fixed on middle partition and bottom plate, be repeatedly used, because
This generally requires to come in more complicated structures such as the ring flange upper surface of ceramic lift tube installation gate core, bushing, cover boards close
Sealing is fixed, and installation, replacement ceramic lift tube are cumbersome, and operator's time that works at high temperature is long, and influences production efficiency.
Especially in antigravity casting high-temperature alloy casting, when steel casting as heat-resisting such as suction pouring, low pressure casting, metal is closed
Golden smelting and pouring temperature is high, and general molten steel casting control is at 1500 DEG C or more, this is just to the sealing fixed structure of ceramic lift tube
Propose very high requirement.It is required that structure is simple, sealed reliable, heat-resisting quantity is good, and is easily installed, replaces, and guarantees casting matter
Amount, improves the service life of ceramic lift tube.And at present in counter-gravity casting equipment ceramic lift tube sealing fixed structure skill
Art is difficult to meet or be not suitable with the antigravity casting production of high-temperature metal alloys, needs to change prior art processes structure
Into.
Summary of the invention
To solve the above problems, the sealing that the present invention provides a kind of antigravity casting ceramic lift tube is fixed
Structure.
The present invention is achieved through the following technical solutions:
A kind of sealing fixed structure of antigravity casting ceramic lift tube, including ceramic lift tube, middle partition, high temperature resistant
Ceramic fibre gasket, cover plate, the ceramic lift tube are equipped with ring flange and are mounted on middle partition, and the ring flange lower end is set
It is equipped with pyroceram fibre gasket, the ring flange circumferential upper part is equipped with centroclinal circular conical surface, the cover plate dress
On ring flange and matched, the cover plate is fixed by screws on middle partition, and is kept and transverse plane on ring flange
Equal, integral seal structure is welded on bottom plate.
As a further optimization solution of the present invention, the ceramic lift tube upper flange plate circumferential upper part male cone (strobilus masculinus) cone angle is
α, and 10 °≤α≤90 °.
As a further optimization solution of the present invention, the cover plate inner conical surface is matched with ring flange circumferential upper part male cone (strobilus masculinus)
It closes, inner conical surface cone angle is α, and 10 °≤α≤90 °.
As a further optimization solution of the present invention, the cover plate inner conical surface, the cone angle of ring flange male cone (strobilus masculinus) are preferred for α
It is 50 °.
Compared with prior art, the beneficial effects of the present invention are: the sealing of the antigravity casting ceramic lift tube is solid
Determine structure, ceramic lift tube ring flange outer circumference surface is in the conical surface, and the matched cover plate inner periphery conical surface is consistent, ring flange
Lower end is equipped with pyroceram fibre gasket (guaranteeing ceramic lift tube and extraneous sealing, do not leak air), and cover plate passes through
Screw is connected and fixed with middle partition, and ring flange upper surface is equal with plane in cover plate, and the sealing for completing ceramic lift tube is fixed.
The structure is simple, reliable, it can be achieved that effective sealing is fixed, and is easily installed, replaces.
Detailed description of the invention

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of sealing fixed structure of antigravity casting ceramic lift tube, including ceramic lift tube (1),
Middle partition (2), pyroceram fibre gasket (12), cover plate (3), the ceramic lift tube (1) are equipped with ring flange (11) simultaneously
It is mounted on partition (2), ring flange (11) lower end is provided with pyroceram fibre gasket (12), ring flange (11) circle
All top is equipped with centroclinal circular conical surface, and the cover plate (3) is mounted on ring flange (11) and matched, cover plate
(3) it is fixed by screws on middle partition (2), and keeps equal with transverse plane on ring flange (11), integral seal structure welding
On bottom plate 6.
When production operation, first pyroceram fibre gasket (12) is put into middle partition (2) groove, then ceramics are risen into liquid
Pipe (1), which is placed in middle partition (2), to be fixed and clamped, and cover plate (3) is then put into the matched ring flange (11) of ceramic lift tube (1)
