Abstract
The utility model relates to a direct flange casting mould which is characterized by comprising an upper mould body and a lower mould body matched with the upper mould body, wherein the upper mould body and the lower mould body are both provided with blind feeder cavities for feeding a casting, pipeline sand core positioning groove mouths for positioning an insert pipeline sand core, flange casting mould cavities for casting the casting, and casting mould sealed groove mouths; a flange bolt sand mould is further arranged on the upper mould body; and a flange bolt hole slot matched with the flange bolt sand mould is formed on the lower mould body. The direct flange casting mould has the benefits as follows: through the technical scheme, the yield of port flange castings reaches more than 95 percent, the degree of surface finish and the precision of produced castings are high, and the quality of the castings is greatly improved.
Description
Technical field
The utility model relates to a kind of cast iron connection pipe fitting terminal port flange and directly pours into a mould the manufacturing forming die structure.
Background technology
In the pipe fitting flange was produced, traditional casting technique was: 1, ingate is opened on tube wall, iron liquid flows into the flange die cavity through the tube wall inner chamber; 2, ingate is opened on flange die cavity wall, foundry goods is carried out feeding by running channel or rising head.
First kind of scheme is in casting solidification, and cool off at last at the ingate position, causes near the foundry goods the ingate to organize crystal grain thick, and be loose, the shrinkage cavity phenomenon is serious, causes foundry goods to be scrapped.Second kind of scheme in casting solidification, the mold-filling capacity deficiency, the misrun phenomenon often appears in the tube wall place, causes foundry goods to be scrapped.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of surface smoothness height, precision height, can greatly improve the direct casting mold of flange of foundry goods.
To achieve these goals, the utility model is to realize by the following technical solutions:
The direct casting mold of a kind of flange, it is characterized in that, comprise the mo(u)ld bottom half body that mo(u)ld top half body and mo(u)ld top half body are suitable, described upper and lower type body is provided with the blind riser die cavity that is used for to feeding a casting, be used for locating the pipeline core locating notch that inserts pipe fitting pipeline core, be used for the flange casting mold die cavity and the casting mold sealing notch of casting; Also be provided with the flange bolt sand mold on described mo(u)ld top half body, described mo(u)ld bottom half body is provided with the flange bolt hole slot suitable with the flange bolt sand mold.
The beneficial effects of the utility model are: the utility model is by technique scheme, and it reaches more than 95% the terminal port flange finished casting rate, and the cast(ing) surface of producing is highly polished, precision is high, can greatly improve the class of foundry goods.
