Description
Technical field
The present invention relates to Casting Equipment technical field, especially a kind of foundry furnace.
Background technology
Antigravity casting is a kind of casting and pouring forming technology to grow up the 1950s.It is made in crucible
Metal overcome gravity and other resistances to fill casting mold from bottom to top along stalk under the effect of the pressure, and obtain under stress
Obtain a kind of method of casting.The difference of casting mold application pressure pattern is filled according to molten metal, antigravity casting can be divided into low pressure
Casting, counter-pressure casting, adjustable pressure casting and suction pouring etc..
It is the dwell time that casting mold inner metal liquid remains to casting to solidify time of end completely under pressure.Pressurize
Time is substantially close to the time required for casting solidification.If the dwell time is too short, metal does not solidify completely, not solidified
Molten metal returns to crucible by stalk, and casting cannot get abundant feeding, or even can not shape, and cause casting to scrap；During pressurize
Between it is long, make that cast gate residual is long, and cleaning is difficult, even stalk outlet can sometimes freezed, influences to produce.Dwell time
The wall thickness of length and casting, alloy species, casting mold property and crystallization and freezing pressure it is relevant.Casting wall is thicker, the knot of alloy
Brilliant temperature range is wider, and the dwell time is longer.
At present, extensive utilization is into casting field for low-pressure casting process, when pressurize is found in actual production process
Between it is most important, but metal melts liquid and often cooled quickly from outside to inside in stalk, due to cooling meat, the gold in mould
Category melts liquid and cannot get good feeding, causes the underproof phenomenon of casting to occur often.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve problem present in above-mentioned background technology, there is provided Yi Zhongzhu
Stove is made, solves the problems, such as that product disqualification rate is high during casting.
The technical solution adopted for the present invention to solve the technical problems is：A kind of foundry furnace, including body of heater, it is arranged on stove
The fire door of body top surface and the stalk for melting liquid for conveying, stalk top are fixedly connected with mould, and described stalk is with fire door
It is divided into stalk upper part and stalk lower part for boundary, described stalk bottom is placed in body of heater, described stalk
Top is placed in outside body of heater, and stalk upper part is located at stalk bosom and is fixedly installed liquid separation part, described liquid separation part
Melt liquid shunting in stalk for guiding, described stalk, which is located at fire door, is fixedly installed seal.
Preferably, described separating tube is made of ceramic materials.
Preferably, described stalk top is into the ellipse for having gone to both ends.
Preferably, described seal is multilayer T-shaped, and its sealability increases with pressure rise in body of heater
By force.
Preferably, described liquid separation part is inverted triangle, and its three angles are circular arc smooth surface.
Preferably, described stalk liquid outlet diameter is less than inlet diameter.
The invention has the advantages that a kind of foundry furnace of the present invention, due to increasing the stalk body being located at outside body of heater
Product make it that in stalk that metal melts liquid cooling solidification speed and is slower than metal in mould and melts liquid setting rate, and adds shunting
Part so that stalk outer wall temperature is not easy to reduce, and ensure that in mould that metal melts liquid and good feeding is obtained before solidification,
Improve the qualification rate of product.
