Abstract
Liquid mouth structure is risen the utility model discloses one kind casting, including cast iron flange, the inner ring of the cast iron flange is provided with graphite annulus, and the graphite annulus is fixed by pressure ring with cast iron flange, the endoporus of the graphite annulus is to rise fluid apertures, and the axle center of the graphite annulus is coaxial with the axle center of cast iron flange.Knowable to from the above, casting of the present utility model rises liquid mouth structure, solves aluminium liquid when pattern block casts and is cooled down at liter liquid mouthful position too fast and condense and occur blocking, and in turn results in the technical problem of Shrinkage Porosity phenomenon, it is ensured that castability.
Description
Technical field
The utility model is related to the manufacturing field of tire-mold, and in particular to one kind casting rises liquid mouth structure.
Background technology
Tire is the annular elastic rubber product rolled in various vehicles or the ground connection mechanically assembled.It is typically mounted on
In alloy rim, vehicle body can be supported, buffer foreign impacts, realized the contact with road surface and ensure the driving performance of vehicle.Tire
Often used under complicated and exacting terms, it subjects the effect of various modifications, load, power and high/low temperature in motion, because
This must have load-carrying properties higher, hauling ability, shock-absorbing capacity.Meanwhile, also require possess high-wearing feature and flexible resistance,
And low rolling resistance and heat generation.
During tire-mold is tire production, pattern block is cast by aluminium liquid and formed.In casting process, aluminium liquid exists
Pressure effect is lower to be passed through to rise liquid mouthful and to rise to carried out in casting mould to fill type.Radiating yet with aluminium liquid at liter liquid mouthful is too fast,
So as to cause aluminium liquid to start to condense, cause diameter relatively small liter liquid mouthful to block today, ultimately result in the mass defect of product；
Reproducibility additionally, due to aluminium is stronger, once the material selection for rising liquid mouthful is improper, rising liquid mouthful will be corroded by high temperature aluminium liquid,
The service life for rising liquid mouthful is reduced, and also can cause to participate in other impurity components, the product quality after influence casting in aluminium liquid.
The content of the invention
The purpose of this utility model is：Overcome the deficiencies in the prior art, there is provided one kind casting rises liquid mouth structure, solves
Aluminium liquid cools down too fast at liter liquid mouthful position and condenses and occur blocking when pattern block casts, and in turn results in Shrinkage Porosity phenomenon
Technical problem, it is ensured that castability；Graphite and ceramic layer are all resistant to elevated temperatures mineral matters, are not occurred with high temperature aluminium liquid any anti-
Should, therefore rise liquid mouthful will not be corroded by aluminium liquid, aluminium liquid after by rising liquid mouthful also will not other impurity produce, and then guarantee
The purity of aluminium liquid composition；Graphite is fixed by pressure ring with cast iron flange, is conveniently changed, and is also only needed more when replacing
The part for having damaged is changed, production cost is significantly reduced.
Technical solution adopted in the utility model is：
Casting rises liquid mouth structure, including cast iron flange, and the inner ring of the cast iron flange is provided with graphite annulus, and the graphite annulus leads to
Cross pressure ring to be fixed with cast iron flange, the endoporus of the graphite annulus is liter fluid apertures, the axle center of the graphite annulus and the axle of cast iron flange
The heart is coaxial.
The further improvement project of the utility model is that the endoporus top of the cast iron flange is provided with bulge loop, and the pressure ring will
Graphite annulus is fixed between pressure ring and bulge loop.
The utility model further improvement project is, the bottom and top of the graphite annulus correspond respectively to pressure ring and convex
The inwall of ring, is respectively equipped with raised A and projection B.
The utility model further improvement project is that the bottom of the raised A flushes with the bottom surface of pressure ring, the projection
The top of B flushes with the top surface of bulge loop.
The utility model further improvement project is that the endoporus sidewall surfaces of the graphite annulus are provided with ceramic layer.
The utility model further improvement project is that the pressure ring is fixed by bolt with cast iron flange.
The utility model further improvement project is that the edge of the cast iron flange is provided with mounting hole.
The beneficial effects of the utility model are：
Firstth, casting of the present utility model rises liquid mouth structure, and aluminium liquid is at liter liquid mouthful position when solving pattern block casting
Cool down too fast and condense and occur blocking, in turn result in the technical problem of Shrinkage Porosity phenomenon, it is ensured that castability.
Secondth, casting of the present utility model rises liquid mouth structure, and graphite and ceramic layer are all resistant to elevated temperatures mineral matters, with high temperature
There is no any reaction in aluminium liquid, therefore rising liquid mouthful will not be corroded by aluminium liquid, and aluminium liquid also will not other after by rising liquid mouthful
Impurity is produced, and then ensure that the purity of aluminium liquid composition.
3rd, casting of the present utility model rises liquid mouth structure, and graphite is fixed with cast iron flange by pressure ring, conveniently carried out more
Change, also only need to change the part for having damaged when replacing, significantly reduce production cost.
Brief description of the drawings：
Fig. 1 is the schematic diagram of the utility model structure.
Specific embodiment：
As shown in figure 1, the utility model includes cast iron flange 1, the inner ring of the cast iron flange 1 is provided with graphite annulus 2, described
Graphite annulus 2 is fixed by pressure ring 4 with cast iron flange 1, and the endoporus of the graphite annulus 2 is liter fluid apertures 3, the axle center of the graphite annulus 2
Axle center with cast iron flange 1 is coaxial；The endoporus top of the cast iron flange 1 is provided with bulge loop 6, and the pressure ring 4 fixes graphite annulus 2
Between pressure ring 4 and bulge loop 6；The bottom and top of the graphite annulus 2 correspond respectively to the inwall of pressure ring 4 and bulge loop 6, set respectively
There is raised A8 and projection B7；The bottom of the raised A8 flushes with the bottom surface of pressure ring 4, top and the bulge loop 6 of the raised B7
Top surface is flushed；The endoporus sidewall surfaces of the graphite annulus 2 are provided with ceramic layer；The pressure ring 4 is consolidated by bolt 5 with cast iron flange 1
It is fixed；The edge of the cast iron flange 1 is provided with mounting hole 9.
When the utility model is used, graphite annulus 2 is fixed in cast iron flange 1 by pressure ring 4, with the fitted bolt 5 of pressure ring 4
It is connected with cast iron flange 1, then lower mould is integrally fastened to by the cast iron flange 1 that mounting hole 9 will be provided with graphite annulus 2；Casting when
Wait, aluminium liquid rises along the endoporus sidewall surfaces of graphite annulus 2 and carries out filling type under pressure.
