Description

A kind of automotive axle sand mo(u)ld for setting emery dust divergence type feeding mechanism makes mould

Technical field

Automotive axle manufacture technology field is the utility model is related to, more particularly to a kind of emery dust divergence type feeding mechanism of setting Automotive axle sand mo(u)ld makes mould.

Background technology

The preparation method of automotive axle mainly has two kinds of forging method and casting.Need to use when making vehicle frame using casting To casting mould, casting mould mainly has two kinds again：One kind is metal pattern, another kind is sand mo(u)ld.Sand mo(u)ld is made by sand mo(u)ld Mould is made, sand mo(u)ld, which makes mould, includes plug hole building core, frame and vehicle bridge model, and frame is provided with sand mold molding bottom plate With the sand mold molding housing being shelved on sand mold molding bottom plate, need to mix in sand and binding agent in sand mo(u)ld manufacturing process （Hereinafter referred to as mulling）So that sand mo(u)ld can be fixed-type.Sand is compacted in existing sand mo(u)ld manufacturing process（Hereinafter referred to as press sand） With the stomata that begun to rehearse on sand mo(u)ld（Hereinafter referred to as shaped air holes）All by manually being inserted with inserted link to complete, therefore during making sand mo(u)ld Arduously；Also existing plug hole building core is truncated cone-shaped in sand mo(u)ld manufacturing process, is shelved in a manner of small end direction Back taper plug hole is molded on vehicle frame model, can return-air be unobstructed when being poured into a mould with ensureing at plug hole during to pour into a mould Although patency, which ensure that the plug hole for the sand mo(u)ld produced can unobstructedly be poured into a mould but cause to take when making sand mo(u)ld It is different to go out the direction of vehicle bridge model and plug hole building core so that vehicle bridge model and plug hole building core can not one Secondary property is taken out, so as to influence production efficiency；Vehicle bridge model and sand mold molding bottom plate be integrally fixed at together, by it is upper lift sand mo(u)ld into Type housing and the sand mo(u)ld of the inframe outside sand mold molding is gone out with sand mold molding bottom plate and vehicle bridge model separation, because which is What sand mold molding bottom plate and vehicle bridge model separated simultaneously, therefore the power for needing to separate is big, easily produces sand mo(u)ld first outside sand mold molding Deviate from frame and cause the demoulding unsuccessfully to cause sand mo(u)ld to make failure, namely existing sand mo(u)ld make the sand mo(u)ld that goes out of Mold Making be with Charging when increase demoulding learies are to ensure that the sand mo(u)ld produced uses is unobstructed.Sand is transported into inframe outside sand mold molding is Completed by manually.Powder can be contained in other raw sand, the presence of powder is unfavorable for being crushed after sand mo(u)ld is finished sharp again In, existing method be using preceding, by manually carrying out sieve wind, existing separate mode can produce larger airborne dust, pollute ring Border and influence health.

Utility model content

The utility model provides that one kind can be separated emery dust and airborne dust is small, not only can guarantee that caused by separating The sand mo(u)ld produced using when charging patency and also do not allow to be also easy to produce that the demoulding scraps sets emery dust divergence type when making sand mo(u)ld The automotive axle sand mo(u)ld of feeding mechanism makes mould, solve by manually sieve emery dust airborne dust it is big, manually upper sand and it is laborious and The problem of charging patency being merely able to during increasing demoulding learies to ensure that the sand mo(u)ld produced uses.

Above technical problem is that solved by following technical proposal：A kind of Automobile for setting emery dust divergence type feeding mechanism Bridge sand mo(u)ld makes mould, including sand mo(u)ld makes mould, and the sand mo(u)ld, which makes mould, includes plug hole building core, frame and vehicle bridge Model, the frame are provided with sand mold molding bottom plate and the sand mold molding housing being shelved on sand mold molding bottom plate, and its feature exists In, in addition to charger and emery dust seperator, the sand mo(u)ld, which makes mould, also includes stomata shaping mechanism, and the vehicle bridge model is worn It is located on the sand mold molding bottom plate, the vehicle bridge model is linked together by lift cylinder with the frame, the cast Hole forming core is truncated cone-shaped, and the bigger diameter end of the plug hole building core is fixed together with the vehicle bridge model, the gas Hole forming mechanism includes the first stomata shaping inserted link of shaping cast hole portion steam vent, pours into a mould cast of the hole portion steam vent from sand mo(u)ld Being extended through in hole includes charger outside sand mo(u)ld, and the charger is provided with discharging opening, the emery dust seperator including circulating fan, Powder spout provided with meal outlet, the casing for going out powder airduct and enclosed construction, the casing is interior to be provided with spreading mechanism, the spreading Mechanism includes the turntable shaft that the spreading rotating disk of horizontal and driving spreading rotating disk rotate, and the casing is provided with air outlet, sand export, position The sand inlet of top and the air inlet below spreading rotating disk are relayed in spreading, the air outlet goes out powder by air duct with described in Airduct connects, it is described go out powder airduct linked together with the import of the circulating fan, the outlet of the circulating fan is the same as described Air inlet is linked together, and the lower end of the air duct is connected with the meal outlet, and the sand inlet is docked at the discharging opening Together, the sand export is located at the top of the sand mold molding housing.Charger is by the raw sand in sandbox during use（Contain powder Measure big sand）Be transported in sand inlet, through sand inlet enter casing and drop to spreading relay scatter by spreading rotating disk and Continue to fall, at the same time circulating fan makes wind rise after air inlet enters, wind rise when powder is also blown afloat together and through going out Air port is flowed out, and sand continues to drop and drop out from sand export.During wind enters powder airduct by air duct, part powder produces heavy Accumulate and drop in powder spout and finally discharged from powder spout, the powder not stockpiled enters circulation in the presence of circulating fan After the import of blower fan interior circulation is formed after the outlet of circulating fan blowout into casing through air inlet again.Both will so as to play Dust separation goes out and prevents the effect of airborne dust.The outer inframe of sand mold molding that sand after separation drops to mould is molded.
