Abstract
This utility model be a kind of utilize rock wool pad replace Runner Exhaust pin with save molten steel structure.Rising head is for the aerofluxus when filling type, often it is designed with exhaust needle, as a example by the volute and discharge manifold disjunctor foundry goods of turbocharger, only exhaust needle fills type and will consume 0.025kg molten steel, one mould two, every four rising heads will consume heat resisting steel 0.2kg, make yield rate decline, exhaust needle mould to be set up and exhaust needle moulding.Now rising head situ is pasted one layer of rock wool, eliminate exhaust needle, make casting yield increase, also simplify formative technology.
Description
Technical field
In order to the rising head top vent air tube of feeding in casting technique, the saving molten steel method replaced with rock wool.
Background technology
In the volute of turbocharger of motor with the casting process of discharge manifold disjunctor, due to volute and discharge manifold
Wall thickness is the most uneven, differs greatly each other, and each position rate of cooling also differs greatly, and the molten steel at wall thickness is often surpassed by the thin place of wall
First cooling meat and molten steel is pulled away, at wall thickness, form shrinkage cavity or loose, typically to being easily generated shrinkage cavity or porous spot is arranged
Rising head, as volute and discharge manifold flange because of the bigger cooling of rising head volume slow, shrinkage cavity position can be supplemented molten steel, make wall thickness
Place will not produce shrinkage cavity and loosen.The big portion of rising head is designed as cylinder, when molten steel up fills type from rising head bottom, inside rising head
Gas can be extruded and be upwardly formed high-pressure area, discharges not as good as from sand grains gap, far fills type, generally at dead head top by affecting rising head
Portion adds and arranges exhaust needle to help aerofluxus, will increase molten steel consumption as arranged rising head air tube, such as 4 flanges of discharge manifold, often
Individual flange all arranges rising head and exhaust needle, and this most more reduces the yield rate of foundry goods.
Summary of the invention
The purpose of this utility model is to utilize rock wool to replace Runner Exhaust pin to save the structure of molten steel.By on rising head housing
Portion is designed to opening, pastes one layer of rock wool at opening part, and when molten steel fills type, in rising head, gas can be by rising head shell top open part
Through rock wool directly from sand mold aerofluxus.
The technical solution of the utility model is, a kind of utilize rock wool replace Runner Exhaust pin with save molten steel structure.Casting
Opening is made in the rising head roof portion of part, pastes one layer of rock wool at opening part.
Notable saving feature of the present utility model is original exhaust needle heat resisting steel to be expended molten steel 0.025kg, and 4 every emit
Mouth about 0.1kg molten steel, a mould two just saving 0.2kg molten steel, 1000 moulds just save 200kg molten steel.Simplify moulder simultaneously
Skill, saves exhaust needle moulding and die-filling.
The fibre board (126 blanket) that described rock wool provides for Jinpeng of Jurong City refractory factory.
Accompanying drawing explanation
Rock wool schematic diagram is pasted at Fig. 1 casting pressing port top.
Accompanying drawing illustrates: 1, foundry goods；2, rising head；3, rock wool；4, riser neck；5, original exhaust needle position.
Detailed description of the invention
A kind of utilize rock wool replace Runner Exhaust pin with save molten steel structure.Original at welt rising head 2 top of foundry goods 1
The position of exhaust needle 5 is installed, pastes one layer of rock wool 3.
Claims (1)
1. one kind utilizes rock wool pad to replace Runner Exhaust pin to save the structure of molten steel, it is characterised in that: at foundry goods welt rising head
Former exhaust needle position, top paste one layer of rock wool.
