Description
Technical field
The utility model is to be related to a kind of holding furnace, belongs to low pressure casting field.
Background technology
Current low pressure casting is aluminium liquid is clamp-oned die cavity to the holding furnace addition pressure of sealing, due to metal furnace shell under high temperature
Bearing capacity is poor, is typically all pressurizeed using relatively low pressure, thus this molding mode is called low pressure casting.This casting
Mode is made, it is necessary to periodically exclude hot-air to injection cold air in stove, furnace temperature fluctuation is big, oxygen-containing air impact high temperature aluminum water,
Accelerate oxidation, slag making, the air-breathing of aluminium water.Body of heater must seal i.e. increase cost makes the influence efficiency that must be stopped production when adding aluminium water again.
Because the frequent gas leakage of body of heater thus has harmful effect to the quality of casting, the anti-leakage function requirement to control system is very tight.It is raw
To have during product compressed air alternately turnover holding furnace, thus inert gas shielding improve aluminium water quality be difficult to carry out.
The content of the invention
The utility model aims to provide a kind of holding furnace for solving low pressure casting defect.
It is applicable the check valve-type low-pressure casting thermal insulation furnace that mechanical pump fills type, including workbench, the electrode of control liquid level, enters row
Air valve, plus aluminium water fire door, keep room, ceramic one-way valve, heating rod, aluminium liquid pressue device, body of heater carry stalk, main furnace body,
Working furnace.
Working furnace, holding furnace are arranged in main furnace chamber, and working furnace horizontal level is less than holding furnace, liquid gold when liquid level suspends
Belong to from casting mold closer to.Ceramic one-way valve is set between working furnace and holding furnace, and ceramic one-way valve makes aluminium liquid enter work under stress
Making furnace chamber cannot return.Holding furnace must be sealed, and working furnace is not required to sealing.
Aluminium liquid pressue device is arranged at main furnace chamber, inlet and the working furnace UNICOM of aluminium liquid pressue device, aluminium liquid pressurization dress
The leakage fluid dram put is arranged at stalk lower end, and inlet is with leakage fluid dram in one plane.Stalk is arranged at main furnace chamber.Control
Level electrode, air inlet and exhaust valve, fire door be may be contained within main furnace chamber, and heating rod is arranged in working furnace, holding furnace.
Work furnace chamber than keep body of heater it is low with reach liquid level suspension when liquid metal from casting mold closer to.Furnace chamber is kept with work
But as long as the connection of furnace chamber check valve gets up to make aluminium water to have entered to return into work furnace chamber under stress.Keep
Stove must be sealed and the furnace chamber that works is not required to sealing.By the body of heater at Electrical Discharge Machine it is hanging it is in larger distance i.e. reduce stalk segment length
Degree, also makes motor space below be conducive to cooling greatly.The passage that the suction inlet and thermal insulation furnace body for leaving pump are communicated, arranges aluminium
Mouth just enters in the lower end of stalk.Liquid mouthful is in one plane conducive to installing and sealing with leakage fluid dram.
Utility model works stove substantially reduces holding furnace cost and also eliminates what body of heater gas leakage brought to product without sealing
Harm.Without to exhaust of being supplied gas in stove, aluminium liquid becomes simple and easy to apply and low cost in inert atmosphere furnace in production process.Stove
Interior temperature is more constant, decreases energy consumption, the problems such as also eliminating increase oxidation that intake and exhaust are brought to aluminium water, be mingled with.
Brief description of the drawings
Fig. 1 is to be applicable the check valve-type low-pressure casting thermal insulation furnace schematic diagram that mechanical pump fills type.
In figure：1 is workbench, and 2 is the electrode of control liquid level, and 3 is air inlet and exhaust valve, and 4 to add aluminium water fire door, and 5 to keep room,
6 is ceramic one-way valve, and 7 is heating rod, and 8 is aluminium liquid pressue device, and 9 carry stalk for body of heater, and 10 is main furnace body, and 11 is work
Stove.
Specific embodiment

Main furnace chamber 10, working furnace 11.
Working furnace 11, holding furnace 5 are arranged in main furnace chamber 10, and the horizontal level of working furnace 11 is less than holding furnace 5, and liquid level suspends
When liquid metal from casting mold closer to.Ceramic one-way valve 6 is set between working furnace 11 and holding furnace 5, and ceramic one-way valve 6 makes aluminium liquid exist
Cannot be returned into work furnace chamber 11 under pressure.Holding furnace 5 must be sealed, and working furnace 11 is not required to sealing.
Aluminium liquid pressue device 8 is arranged at main furnace chamber 10, inlet and the UNICOM of working furnace 11, aluminium liquid of aluminium liquid pressue device 8
The leakage fluid dram of pressue device 8 is arranged at the lower end of stalk 9, and inlet is with leakage fluid dram in one plane.Stalk 9 is arranged at master
Furnace chamber 10.Control level electrode 2, air inlet and exhaust valve 3, fire door 4 may be contained within main furnace chamber 10, heating rod 7 be arranged at working furnace 11,
In holding furnace 5.
