Description

A kind of Casting Equipment

Technical field

The utility model relates to a kind of alloy refining cast form equipment.

Background technology

At the beginning of the blank of low pressure casting method can be traced back to last century.Be applicable to aluminium alloy and be 1917 in France, the imagination that nineteen twenty-four proposes in Germany, but do not form large-scale industrial production.1945 years after World War II for the object of business starts to produce.The slow La Lumo in pool of the U.S. in 1958 it this has used in a large number aluminium alloy castings on the engine part of kart, and has adopted low pressure casting method.It is about nineteen fifty-seven that low pressure casting method is introduced into China, but really causes the attention of industry, starts to carry out various research, introducing equipment since about nineteen sixty.But this epoch-making process of general knowledge in the past of having broken, does not almost have rising head, there is diverse difficulty compared with the technology of the gravity metal casting of establishing as a kind of " technology ", therefore the reaction of industry is colder.Under this situation, the light-duty vehicle of 1961 becomes low pressure casting method at the practical beginning of China with the production of air cooling cylinder head.Later development is very fast, overcoming after multiple technical barriers, the advantages such as type automation are filled in high, the easy realization of stock utilization that utilizes low pressure casting method to have, and centered by automobile component, have progressively established the firm status of the main casting of light alloy casting.In the output of aluminium alloy castings, it is about 50% that low pressure casting product have accounted for, and with its huge output and good quality and be world-famous for.Product expands automobile associated components to.Particularly within 1970, widely apply on wheel hub, and along with requirements such as automotive light weight technology and raising performances, under the strict demand of the complex internal quality of in the past having no precedent and engineering properties, the use in cylinder head, cylinder block also increases gradually later.But current low pressure casting mode is after the refining of aluminium liquid, to pass through casting ladle metaideophone in low pressure casting machine holding furnace, and the aluminium liquid of holding furnace keeps temperature by the heating rod radiation heating on top.On the aluminium liquid surface of airtight holding furnace, apply low pressure dried compressed air pressure, aluminium liquid rises by soaking stalk in aluminium liquid, is pressed in the mold cavity of the top being connected with stove.Aluminium liquid is slowly to start filling from the bottom of die cavity, keeps the pressure after coagulation of a period of time.Finally when being cooled to solid-state temperature, foundry goods just can take out below foundry goods.This kind of mode is because the heating rod radiation heating on top keeps temperature, and temperature of aluminum liquid is inhomogeneous, and upper temp is higher, and bottom is on the low side; After the refining of aluminium liquid, in metaideophone process, meeting oxidation is air-breathing, weakens refining effect; What enter holding furnace is normal temperature compressed air, has increased the oxidation of aluminium liquid in holding furnace, and the high temperature air in release rear hearth directly enters atmosphere in addition, because thermal loss causes energy waste.

Summary of the invention

The purpose of this utility model is for the problems referred to above, the utility model proposes alloy refining low pressure casting integration apparatus.

The technical scheme that realizes above-mentioned purpose is: in air injection machine frame, mould is installed, in air injection machine frame lower, holding furnace is installed.Holding furnace is divided into liquid feeding refining chamber and two of compression casting chambers furnace chamber, and the channel connection with gate valve is arranged at two furnace chamber bottoms; Filter is housed on passage.Impregnated electric heater is equipped with respectively in two furnace chamber bottoms, and in liquid feeding refining chamber, bottom even arranges air brick, and air brick is connected with tanks of compressed inert gas by air inlet pipe, and dynamoelectric proportion valve A is housed on steel pipe; Be provided with fire door in liquid feeding refining chamber middle and upper part.Two furnace chamber tops have the steel pipe with motor-driven valve to be communicated with.Be connected with the cast gate of mould by stalk, pipette on top, compression casting chamber, screen pack is equipped with in stalk bottom.On top, compression casting chamber, the relief tube with dynamoelectric proportion valve B is housed, relief tube is connected with air accumulator.

Aluminium liquid does not contact with air after the aluminium refining of liquid feeding refining chamber, has avoided the oxidation again of aluminium liquid, can the good foundry goods of workmanship.Meanwhile, the utility model holding furnace adopts impregnated electrical heating, improves the uniformity with the efficiency of heating surface and temperature of aluminum liquid.After die casting completes, the inert gas of high temperature does not directly enter atmosphere, again utilizes after purifying but enter air accumulator, has improved the utilization rate of natural resources and energy resources.
