Description
Technical field
The utility model relates to casting processing technique field, specifically refers to a kind of running gate system of argosy turbocharger air compressor shell foundry goods.
Background technology
Compressor casing foundry goods is the important spare part of large-scale marine turbosupercharger, casting structure is complicated, the most thick 4mm of thin-walled, thickest 30mm, and the acceptance requirement of the compressor casing casting finished products produced is very high, whole product needed carries out UT/MT Non-Destructive Testing, therefore very high to the designing requirement of the running gate system of compressor casing foundry goods.Original running gate system is connect circular cross-runner 2 ' under sprue 1 ', iron liquid is entered from compressor casing foundry goods outer radial again by 5 road ingates 3 ', because the ingate on ingate 3 ' is positioned at the side of compressor casing foundry goods, make to fill type steady not, iron liquid likely taps into into die cavity from circular cross-runner 2 ' die joint direct clearance, return again after direct impact core, the iron liquid that the iron liquid and the later stage that return enter mixes, iron liquid can be caused to produce secondary oxidation, the metal oxide produced and sulfide, free graphite floats to cast(ing) surface together, or the place such as the dead angle be trapped in foundry goods and core lower surface, broken sand and slag inclusion is produced in foundry goods, filling type steadily also can not make molten metal in casting process, produce turbulent flow, eddy current or cutout, and be easily involved in gas, formed in foundry goods and be involved in pore, these problems all can make the quality of compressor casing foundry goods influenced, cause Product Acceptance Review defective, in addition, the horizontal line in foundry goods centre is higher than excircle, iron liquid enters from the 5 road ingates 3 ' be communicated with circular cross-runner 2 ' from compressor casing foundry goods outer radial, could fill iron liquid toward foundry goods centre (position that horizontal line is higher) after position lower for foundry goods horizontal line is first filled up by needs, foundry goods centre is easy to produce cold shut defects.
Utility model content
The technical problems to be solved in the utility model is, giving security, whole to fill type steady, reduce molten metal in casting process, produce turbulent flow, eddy current or cutout, reduce the running gate system of the argosy turbocharger air compressor shell foundry goods of broken sand, slag inclusion and cold shut defects etc.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of running gate system of argosy turbocharger air compressor shell foundry goods, comprise sprue, ingate, sprue is connected by running channel with ingate, described running channel comprises the cylindricality transition running channel, the bar shaped transition cross gate that are connected successively, sprue is communicated with cylindricality transition running channel, and cylindricality transition running channel radial communication bar shaped transition cross gate, described bar shaped transition cross gate is vertically provided with sprue, during cast, the ingate be positioned on sprue is located at the bottom of compressor casing foundry goods.
Compared with prior art, the utility model has the advantage of: ingate is positioned at the bottom of compressor casing foundry goods, iron liquid whole injection from bottom when making to fill type, iron liquid is made to increase stably in the axial direction, flow into other positions of casting mold again, can ensure that the whole type that fills is steady, reduce the generation turbulent flow of molten metal in casting process, eddy current or cutout, be not easy to be involved in gas when making to fill type, reduce and be involved in pore in foundry goods; Change original circular cross-runner, iron liquid can not tap into into die cavity from circular cross-runner die joint direct clearance, the secondary oxidation problem that the iron liquid returned again after solving impact core mixes with the iron liquid that the later stage enters and produces, and reduces broken sand and slag inclusion; Cast structure of the present utility model is simple, improves labor productivity, has saved production cost.
Described bar shaped transition cross gate is three and is uniformly distributed along cylindricality transition running channel circumference, and cylindricality transition running channel is connected respectively with three bar shaped transition cross gates.Article three, bar shaped transition cross gate is uniformly distributed along cylindricality transition running channel circumference that iron liquid can be made to inject is relatively even, and whole to fill type steady, reduces defect.
Sprue on every bar bar shaped transition cross gate is two; When this structure makes iron liquid be injected into the bottom of compressor casing foundry goods almost simultaneously, the cold shut defects that foundry goods centre easily produces is solved.
The cross section of described sprue is bar shaped, and namely ingate is bar shaped, the circular ingate that this structural change tradition rising pouring adopts, ingate is larger, and thermal center point is larger, affects the quality of foundry goods, so the utility model ingate is set to bar shaped, greatly reduce thermal center point, improve the quality of foundry goods.(casting thermal center refers to that molten iron is in process of setting, and foundry goods internal ratio surrounding metal solidifies node or regional area slowly, is alternatively the place of last cooled and solidified.)
