Description
Technical field
The utility model belongs to Casting Equipment, particularly a kind of low-pressure casting thermal insulation furnace.
Background technology
Low pressure casting is Counter-gravity Casting, its objective is that solving running gate system in casting fills the contradiction of type and feeding.In gravitational casting for fill type steadily, avoid pore, slag inclusion, generally all adopt bottom filling, therefore in casting mold, temperature field distributes and is unfavorable for riser feeding.Low pressure casting utilizes crucible internal gas pressure by from bottom to top filling casting mold of molten metal dexterously, under low pressure, keep running channel and Feeding channel to unite two into one, all the time maintain the uniformity of mold temperature gradient and pressure, thereby solve the contradiction of filling type stationarity and feeding in gravitational casting, and casting quality is significantly improved, also corresponding raising of product yield simultaneously.Due to the good characteristic of low pressure casting, air injection machine is developed rapidly both at home and abroad, has developed many kinds of air injection machines, for the production of reality.The simple foundry goods of inner-cavity structure that adopt single stalk all-metal mold to produce at present more; all-metal mold is difficult to produce heavy parts more than 50kg; though and adopt full sand mold low-pressure casting method can produce the pressure hull foundry goods of large-scale inner-cavity structure complexity; but for ultra-large type foundry goods; because single stalk design running gate system is in order to protect consecutive solidification condition; running channel is all very large; technique is large by the aluminium water yield; be difficult to ensure end feeding requirement because the long aluminium coolant-temperature gage of running channel declines, also be just difficult to ensure the production of quality product.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, and operation is convenient, can meet the low-pressure casting thermal insulation furnace of ultra-large type cast casting technological requirement.
The technical scheme that the utility model technical solution problem adopts is: low-pressure casting thermal insulation furnace comprises shell body, body of heater, locking device, sealing ring, heater, binding post, electric appliance protective shield, be characterized in that the cross section that is incubated crucible is for oval, the bottom of insulation crucible is placed in above bottom of furnace body, the upper edge of insulation crucible is fitted on crucible supporting, crucible supporting is placed in above the body of heater of surrounding, between insulation crucible and body of heater around, heater is housed, shell body is equipped with in the outside of body of heater, edge on shell body is fixedly equipped with in shell body upper end, binding post and electric appliance protective shield are housed respectively on shell body, above insulation crucible, stove plate on holding furnace is housed, holding furnace upper cover is housed above stove plate on holding furnace, above holding furnace upper cover, place casting mold, on holding furnace, between stove plate and holding furnace upper cover, locking device and air inlet pipe are housed, on holding furnace upper cover and shell body, between edge, seal with sealing ring, shell body right upper portion is equipped with escape pipe, escape pipe is communicated with low-pressure casting thermal insulation furnace inner chamber top, a holding furnace upper cover left side, stalk of the each plug-in mounting in right both sides, stalk lower end is placed in the aluminium water in insulation crucible.
The beneficial effects of the utility model are: low-pressure casting thermal insulation furnace is simple in structure, and operation is convenient, safe and reliable, makes foundry goods dense structure, and good quality of product can meet quality and the manufacturing technique requirent of super large part overpressure resistant aluminum housing.
