Abstract
The invention provides a runner structure with a downsprue. The runner is provided with a slope surface, wherein the lower end of the slope surface is connected with the top opening of the downsprue; a groove is formed on the slope surface; the included angle between the bottom surface of the groove and the horizontal plane is less than that between the slope surface and the horizontal plane. The runner structure with the downsprue, provided by the invention, can prevent liquid from splashing in a pouring process, ensures the high stability and quickness during mold filling of fluid, reduces oxidation and shortens mold filling time.
Description
Technical field
The present invention relates to a kind of down gate flow passage structure, belong to field of mechanical technique.
Background technology
Along with the development of foundry engieering, the requirement of intensive manufacture, the design of rational casting technique is to the large-scale production in product later stage, and the lifting of yield rate index is very crucial.Enter the entrance of die cavity as liquid (iron liquid or molten steel), the whether reasonable in design of down gate also show very important effect in running gate system.Liquid splash, causes cost to waste.Cast is not steady, and liquid flowing state is disorderly, there will be the problems such as oxidation, is unfavorable for the steady quality of foundry goods.
Summary of the invention
The invention provides a kind of down gate flow passage structure, the above defect can be overcome, there will not be cast not steady, the phenomenon of liquid flowing state disorder.
For solving above technical problem, the invention provides following technical scheme: a kind of down gate flow passage structure, described runner has domatic, and domatic lower end connects the top mouth of down gate; Domaticly be provided with groove, the angle of described groove floor and horizontal plane is less than angle that is domatic and horizontal plane.
Further, described groove and domaticly to cross in bottom, the common top mouth connecting down gate.
Further, be describedly domaticly less than 75 ° with the angle of horizontal plane,
be greater than 30 °.
Further, the angle of described groove and horizontal plane is less than 60 °, is greater than 15 °.
This down gate flow passage structure that the present invention relates to, by the checking to wherein down gate design, can avoid the liquid splash in casting process, ensures that fluid fills type steadily rapid, reduces oxidation, reduce filling time.Thus obtain good foundry goods.
Accompanying drawing explanation
Fig. 1 is a kind of down gate runner of the present invention top view;
Fig. 2 is a kind of down gate runner of the present invention A-A sectional view.
Detailed description of the invention
As depicted in figs. 1 and 2, described down gate runner has domatic 2, is domaticly provided with groove 3, domatic lower end to
down gate1 direction extends, and the angle of described groove 3 bottom surface and horizontal plane is less than angle that is domatic and horizontal plane.
Described groove 3 bottom surface has the arc line shaped of gathering, the arc line shaped of this gathering to
down gate1 extends.
Described domatic 2 are less than 75 ° with the angle of horizontal plane,
be greater than 30 °.
Described groove 3 is less than 60 ° with the angle of horizontal plane, is greater than 15 °.
This down gate flow passage structure that the present invention relates to, be conducive to reducing liquid splash, after scale uses, reduce costs, the advantage especially for the high-nickel material of high alloy element and the product expression of heat-resisting steel material is more obvious; Be conducive to cast more steady, every type 1-2 duration of pouring second can be reduced, ensure less temperature range, be conducive to the uniformity of solidifying, the inherent quality of improving product; Down gate is separated, becomes an independently unit, adopt independent equipment to make.Popularization for current shell mold technical operation creates condition.It is that the exploitation of high-end product, particularly turbocharger housing etc. and large-scale production establish good basis.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
