Abstract
The present invention is a kind of apparatus that monitoring casting mold in suction pouring room metals run out, instrument is using highly sensitive temperature sensor and pressure sensor probe while being mounted on suction casting ceiling portion, the micro variation for casting chamber interior once the micro variation of temperature of metalling run out and molten iron break through the instantaneous vacuum degree of type chamber is inhaled in sealing using casting mold, parallel connection signals that vacuum gulp valve is made to close vacuum passage, open air supply passage, so that vacuum degree is declined stopping rapidly and inhale casting, avoids expansion of metalling run out.This device, which is avoided that use, has contact or being blocked for optical signal that can only monitor local location, but can cast room all standing to inhaling, so that suction pouring equipment be protected not to be destroyed.
Description
Technical field
The monitoring device device that foundary industry antigravity casting casting mold metals run out.
Background technique
In the antigravity casting field of foundary industry, suction pouring is a kind of casting method of complete anti-gravity, vacuum
Inhaling casting must make casting mold be in vacuum state, and the pressure difference established using vacuum state makes molten iron by atmospheric pressure from crucible
Molten iron is pressed into casting mold type chamber from stalk.Suction pouring has good cavity filling and feeding, and what mainly molten iron was subject to fills
Type pressure is influenced by vacuum degree.Vacuum degree is higher, fills that type is more complete, and feeding is also more thorough, but vacuum degree is excessively high and can make casting mold
Casting mold squeeze crack will be metal run out to the pressure of type chamber if mould strength is lower than the mold filling pressure of molten iron by molten iron
Failure.
In the prior art to prevent suction pouring from generating the destruction to casting room is inhaled to metalling run out for casting mold, have in mould wall
It is embedded to conducting wire, has the various sensors of installation or infrared imaging, but casting mold, after suction is cast and installed in room, surrounding space is narrow, and by
It metals run out the uncertainty at position in casting mold, various monitoring devices cannot not only cover whole casting molds, and reflection speed is not caught up with yet
The generation speed that molten iron destroys suction casting room after leaking out.
Summary of the invention
Monitoring that can comprehensively to casting mold all surface when metalling run out present invention aim to address suction pouring casting mold, one meets
Casting mold metals run out and can be thorough in time except vacuum, a kind of device for making molten iron flow back from stalk rapidly.
The technical scheme is that in one high sensitivity temperature sensor probe of suction casting indoor location of sealing and one
The pilot circuit of high sensibility pressure transducer probe, probe signal and vacuum gulp valve is connected in parallel.
Remarkable result of the invention is when casting mold once metals run out, and when molten iron is gone out outside casting mold, suction casting room temperature has micro-
The variation of amount, temperature sensor probe will elicite variation and signal, meanwhile, the probe of pressure sensor loses casting in molten iron
When type type chamber is constrained and gone out, the variation of a vacuum degree is also had, because metalling run out is that pressurization generates when filling type and completing,
Once this balance is destroyed, vacuum degree also has a bust, utilizes the abrupt transients of temperature and vacuum degree, the letter of sensor
Number any one preferential conducting, is immediately controlled vacuum gulp valve commutation, vacuum degree decline can avoid the further destruction metal run out
Expand, this device can also be such that optical signal is blocked to avoid using the sensor of optical signal, can cover casting mold whole.
Detailed description of the invention

Specific embodiment
Casting mold 2 is housed in the mounting base for inhaling casting room 1, stalk 3 is housed in suction casting 1 bottom surface of room of 2 lower part of casting mold, is being inhaled
It casts equipped with temperature sensor probe 4 and pressure sensor probe 5 at the top of room 1, when temperature sensor probe 4 or pressure sensor are visited
First 5 when having signal outflow, and power loss commutates vacuum gulp valve 7 immediately, opens air supply passage, discharges vacuum, stops inhaling casting.
