Abstract
The present invention discloses annular long cast member spiral and drenches with rain casting, by cast member model is vertically installed in moulding sandbox, cast member model is provided with individual layer or multilayer cast circle, described cast circle is longitudinally volution, surrounding is uniformly distributed and is provided with multiple spiral and waters, cast circle connection sprue gate, upper end, vertical pouring method is adopted during cast, slowly iron liquid is poured into from sprue gate, iron liquid evenly enters die cavity by 360 °, cast circle, liquid level helically rotates and upwards shifts to model upper end, rear cooling forming. Instant invention overcomes the deficiencies in the prior art, take vertical pouring method, individual layer or multi-layer helical is adopted to drench with rain casting, ensure that iron liquid 360 ° evenly enters die cavity, liquid level helically rotates and rises to floating, is conducive to the folder slag in iron liquid, and impurity is discharged to cap mouth smoothly, and ensure the quality of foundry goods, it is to increase yield rate.
Description
Technical field
The present invention relates to cast member processing technique field, specifically belong to annular long cast member spiral and drench with rain casting. Background technology
When the above high-carbon of casting length 800mm (carbon > more than 2.0) annular element, during casting, difficulty is bigger. Because its constructional feature is that diameter is big, thin-walled, complex structure, easily produces crackle after casting. Annular cast, structure is closed, produces bigger stress, it is not easy to release when solidifying, and when being subject to core and hinder, extremely easily produces distortion or crackle, even causes foundry goods to be scrapped, bring financial loss to foundry; Degree of compactness is poor, and during foundry goods, in iron liquid, impurity is not easily got rid of.
Summary of the invention
It is an object of the invention to provide annular long cast member spiral to drench with rain casting, overcome the deficiencies in the prior art, take vertical pouring method, adopting individual layer or multi-layer helical to drench with rain casting, ensure that iron liquid 360 ° evenly enters die cavity, liquid level helically rotates and rises to floating, be conducive to the folder slag in iron liquid, impurity is discharged to cap mouth smoothly, and ensure the quality of foundry goods, it is to increase yield rate.
The technical solution used in the present invention is as follows:
The long cast member spiral of annular drenches with rain casting, by cast member model is vertically installed in moulding sandbox, being provided with individual layer or multilayer cast circle on cast member model, described cast circle is longitudinally volution, and surrounding is uniformly distributed and is provided with multiple spiral and waters, cast circle connection sprue gate, upper end, adopting vertical pouring method during cast, slowly poured into by iron liquid from sprue gate, iron liquid evenly enters die cavity by 360 °, cast circle, liquid level helically rotates and upwards shifts to model upper end, rear cooling forming.
Compared with the prior art, the useful effect of the present invention is as follows:
The present invention takes vertical pouring method, adopts individual layer or multi-layer helical to drench with rain casting, ensures that iron liquid 360 ° evenly enters die cavity, liquid level helically rotates and rises to floating, is conducive to the folder slag in iron liquid, and impurity is discharged to cap mouth smoothly, and ensure the quality of foundry goods, it is to increase yield rate.
