Abstract
The utility model relates to a casting furnace, including having the plus -pressure furnace of stalk, the plus -pressure furnace linked to each other with the stock solution stove through the communicating pipe that is equipped with the ooff valve, be equipped with in the plus -pressure furnace respectively with lower limit level sensor and upper limit level sensor that the ooff valve is connected, the pipe diameter from bottom to top of stalk increases. The utility model discloses a casting furnace can detect the metal liquid surplus in the furnace body to the automatic interpolation to standard liquid level can not overflowed when lacking, can also in time remind operating personnel simultaneously when reserve metal fluid low, has obvious meaning to improvement product quality and production efficiency.
Description
Technical field
This utility model is related to Casting Equipment, is concretely foundry furnace.
Background technology
In current forging field, low pressure casting method has been obtained for extensive utilization.Existing foundry furnace includes
Body of heater, body of heater is provided with fire door, and fire door is provided with stalk, there is the metal liquid of molten condition in body of heater.When being cast, rise
Liquid pipe upper end connects casting mould, to pressurizeing in body of heater, metal liquid is defeated in casting mould by stalk, then carries out
Cooling casting.
In casting process, with the carrying out of casting, the metal liquid in body of heater can gradually be filled in casting mould, have
When be busy with other work due to casting personnel, the metal liquid in stove usually not enough can cause cast article because liquid measure
Defect.
Utility model content
This utility model provides a kind of foundry furnace, and the metal liquid surplus in body of heater can be detected, and certain
Added automatically in degree.
This utility model foundry furnace, including the plus-pressure furnace with stalk, plus-pressure furnace is by being provided with communicating pipe of switch valve
It is connected with liquid storage stove, the bottom limit level sensor and upper limit level sensing being connected with the switch valve respectively is provided with plus-pressure furnace
Device, the caliber of stalk increases from bottom to top.The upper end of stalk connects the die cavity of casting mould, after pressurizeing to plus-pressure furnace, plus
Pressure stove in molten condition metal liquid just Jing stalks enter casting mould die cavity, now switch valve for close.Work as pressurization
After metal liquid in stove is dropped to below bottom limit level sensor, bottom limit level sensor-triggered switch valve is opened, liquid storage stove
Interior metal liquid enters plus-pressure furnace by communicating pipe, after the metal liquid in plus-pressure furnace exceeds upper limit level sensor, on
Limit liquid level sensor controlling switch valve is closed, and is caused danger with ensureing that metal liquid will not overflow.Stalk is set to into caliber
Increase from bottom to top, so just increase the capacity in stalk upper tube, stalk upper metal liquid coagulates when making casting
Gu speed is slower than the setting rate that casting mould inner metal liquid body solidifies most slow component, so as to ensure that casting mould inner metal liquid
Before body solidifies completely, the supplement of metal liquid can be obtained by stalk always, make casting yield be effectively improved.
Further, the bottom of liquid storage stove connects the communicating pipe higher than pressurization furnace bottom in the way of entrance is higher than outlet
Connect the bottom of plus-pressure furnace and liquid storage stove.So without passing through extra power when from liquid storage stove to plus-pressure furnace supplement metal liquid,
Plus-pressure furnace just can be flowed to by the action of gravity of metal liquid itself.Simultaneously by communicating pipe located at plus-pressure furnace and the bottom of liquid storage stove
Portion, enables metal liquid farthest to utilize, and will not be detained in liquid storage stove.
Further, the liquid level sensor of connection alarm device is provided with liquid storage stove, if the metal liquid in liquid storage stove
Surpluses are less than liquid level sensor, then the alarm device of connection is triggered by liquid level sensor, and operator are pointed out.
Preferably, it is respectively equipped with heat-insulated knot on the outside of bottom limit level sensor, upper limit level sensor and liquid level sensor
Structure, such as silicide heat insulation foam etc., it is to avoid overheated metal liquid damages sensor, the heat-barrier material of generally 3000 DEG C of ability is equal
It is applicable.
Optionally, described switch valve is electromagnetic valve structure, and electromagnetic valve is one kind common at present by signal of telecommunication control
Valve, simplify can overall structure using the switch valve of electromagnetic valve structure, reduce production cost.
Foundry furnace of the present utility model, can detect to the metal liquid surplus in body of heater, and when lacking certainly
Dynamic addition will not overflow to standard liquid level, while operator can also be in time reminded when standby metal liquid is not enough, it is right
Improving product quality and production efficiency has obvious meaning.
Specific embodiment with reference to embodiments, remakes further specifically to the above of the present utility model
It is bright.But this scope for being interpreted as the above-mentioned theme of this utility model should not be only limitted to Examples below.New without departing from this practicality
In the case of the above-mentioned technological thought of type, the various replacements made according to ordinary skill knowledge and customary means or change,
Should be included in the range of this utility model.
Description of the drawings
Fig. 1 is the structural representation of this utility model foundry furnace.
Specific embodiment
As shown in Figure 1 foundry furnace of the present utility model, including the plus-pressure furnace 1 with stalk 3, the caliber of stalk 3 by
Under be increased up, so just increase the capacity in the upper tube of stalk 3, the upper metal liquid of stalk 3 is solidifying when making casting
Gu speed is slower than the setting rate that casting mould inner metal liquid body solidifies most slow component, so as to ensure that casting mould inner metal liquid
Before body solidifies completely, the supplement of metal liquid can be obtained by stalk 3 always, make casting yield be effectively improved.
Plus-pressure furnace 1 is connected by being provided with the communicating pipe 5 of the switch valve 6 of electromagnetic valve structure with liquid storage stove 2.The bottom of liquid storage stove 2 is higher than to add
Pressure stove 1 bottom, and communicating pipe 5 connect the bottom of plus-pressure furnace 1 and liquid storage stove 2 in the way of entrance is higher than outlet, make liquid storage stove 2
In metal liquid be easier to flow to plus-pressure furnace 1.The bottom limit level being connected with the switch valve 6 respectively is provided with plus-pressure furnace 1
The liquid level sensor 9 of connection alarm device is provided with sensor 8 and upper limit level sensor 7, liquid storage stove 2.Pass in bottom limit level
Sensor 8, upper limit level sensor 7 and the outside of liquid level sensor 9 are respectively equipped with the heat insulation structural of the heat-insulated cotton structure of silicide, to protect
Shield sensor will not be by the high temperature failure of metal liquid.
