Abstract
The utility model relates to the forming technical field of intercoolers and relates to a metal-mould gravity quiescent pouring mould for an intercooler air chamber. A sprue is formed at one side in the pouring mould of the intercooler air chamber; the sprue is communicated with a mould cavity of the mould by an ingate; a slag blocking strip is formed at a casting ladle port of the sprue; a bent slag trap is formed at the bottom of the sprue; and a being mechanism is arranged on the ingate. The metal-mould gravity quiescent pouring mould has the advantages that the slag blocking strip is formed at the casting ladle port of the mould for filtering oxide skin and slag on the topside of the molten aluminum; the bent slag trap is formed at the bottom of the sprue, so that the worst molten aluminum entering the mould firstly is collated in the slag trap; the bending mechanism is arranged in the ingate of the mould, and the thickness of the ingate is controlled, so that the slag of the molten aluminum and the oxide skin are further removed.
Description
Technical field
The utility model charge air cooler field shaping technique relates to a kind of casting mold that improves charge air cooler air chamber qualification rate, can make slag in the aluminium liquid and oxide skin few product that enters of trying one's best, and the sidewall of charge air cooler air chamber is carried out effective feeding.
Background technology
Turbo charged engine must reduce intake air temperature with charge air cooler, to improve engine power, prevents the faults such as the too high and pinking of engine combustion temperatures, reduces the content of the NOx in the engine exhaust, reduces air pollution.Market prospects are boundless.Present charge air cooler is comprised of a fuse and two air chambers.The manufacture craft of charge air cooler air chamber mainly contains sand mold gravitational casting, metal mold gravity casting now.General be pilot adopts the sand mold gravitational casting, and in batches larger product adopts metal mold gravity casting.The sealing experiment qualification rate of adding up domestic charge air cooler air chamber metal type cast according to AUTHORITATIVE DATA is 80%-90%, and sealing is tested low qualified, has increased the cost of foundry goods.Analyzing its reason mainly is because the pushing off the slag shelves oxide skin ability of running gate system is relatively poor, causes slag and oxide skin content in the product product higher.
The major defect of above-mentioned this running gate system (referring to Fig. 1-4) is:
1, the thickness of ingate 3 sidewalls is thicker, and now general design thickness is 6-12mm, pushing off the slag shelves oxide skin weak effect.
2, sprue 2 slag trap 4 collection slag ability bottom, analyze its reason, mould is when verting, aluminium liquid flows in the sprue 2 fast, when aluminium liquid arrives slag trap 4, the backflow of can up rolling of aluminium liquid, secondary oxidation is serious, and the second-rate aluminium liquid that refluxes can enter die cavity together with follow-up aluminium liquid, causes that slag inclusion folder oxide skin increases in the product 1.
3, the cast oral area 5 of sprue 2 does not arrange slag blocking structure, and the oxide skin on casting ladle upper strata is entered in the sprue together with scum silica frost.
Summary of the invention
The purpose of this utility model provides slag inclusion and the few charge air cooler air chamber metal gravity quiescent pouring mould of oxidizing component in a kind of product of cast.
The purpose of this utility model is achieved in that
Charge air cooler air chamber metal gravity quiescent pouring mould, side in charge air cooler air chamber casting mold is provided with sprue, be communicated with by ingate between sprue and the mold cavity, casting ladle mouth at sprue is provided with the pushing off the slag bar, arrange one in the bottom of sprue and curve slag trap, be provided with turning mechanism on the described ingate.
Above-mentioned curves slag trap for a U-shaped structure is extended in the bottom of sprue.
Turning mechanism on the above-mentioned ingate is S type or N-type structure, and the middle part of S type or N-type structure is provided with overstriking section, two is thin neck.
The thickness of above-mentioned ingate and sprue junction is 1.5 times of charge air cooler air chamber product wall thickness, and the wall thickness of ingate is 0.8 times of wall thickness charge air cooler air chamber product.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the ingate at mould arranges a turning mechanism, and the thickness of control ingate, both ingate had been arranged to the structure of the semi open model of S type or N-type, the wall thickness of ingate and sprue junction is designed to 1.5 times of product wall thickness, the wall thickness of ingate is designed to 0.8 times of wall thickness, adopt this semi open model structure, can guarantee good stamp speed, can play the descale effect that well removes slag again.
2, at turning slag trap of bottom design of sprue, when making die flip, enter at first the relatively poor aluminium liquid of die quality and can be good at being stored in this and curve in the slag trap, do not reflux, do not enter into product.
3, at the feed inlet end of sprue, design a pushing off the slag bar, the top section that enters the aluminium liquid in the sprue is lived by pushing off the slag mouth shelves, slag and the oxide skin content of lower floor are little in the running channel, and the aluminium liquid that quality is high enters in the sprue, has guaranteed the quality of aluminium liquid.

The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 5-10: charge air cooler air chamber metal gravity quiescent pouring mould, side in the charge air cooler air chamber is built mould 60 is provided with sprue 20, be communicated with by ingate 30 between sprue 20 and the mold cavity 10, casting ladle mouth 21 at sprue 20 is provided with pushing off the slag bar 22, arrange one in the bottom of sprue 20 and curve slag trap 23, be provided with turning mechanism on the described ingate 30.
Above-mentioned curves slag trap 23 for a U-shaped structure is extended in the bottom of sprue.
Turning mechanism on the above-mentioned ingate 30 is S type or N-type structure, and the middle part of S type or N-type structure is provided with overstriking section 32, two is thin neck 31,33.
