Described a kind of liquid metal filling fluidised form visualizer, is characterized in that described endoscope 1 is made by two-way mirror 8 and endoscope probe 9, and endoscope 1 is placed in sheath 10.
Described a kind of liquid metal filling fluidised form visualizer, it is characterized in that described steel pipe 2 is to be embedded in casting mold 6, the external diameter of the internal diameter size of steel pipe 2 and endoscope sheath 10 matches, and the position being embedded in casting mold 6 of steel pipe 2 is determined according to the position of metal liquid stream outlet 7 and the visual range of endoscope 1.
Described a kind of liquid metal filling fluidised form visualizer, is characterized in that described position limiting clamp 3 is fixed on one end of steel pipe 2, fixes and control the observation position of endoscope 1.
Utilize liquid metal filling fluidised form visualizer, the step of the molten metal fluidised form of observing is as follows:
1. open the setting video state of endoscope 1 and computer 5;
2. start casting of molten metal, molten metal exports 7 by metal liquid stream and enters in casting mold 6;
By endoscope 1 observe molten metal flow state, then by signal transmssion line 4 by video signal transmission in computer 5;
4. 5 recorded video of pair computer are carried out observation and analysis, thereby judge that rationally whether casting technique.
beneficial effect of the present invention:
1. when the present invention can directly observe molten metal and leaves ingate, fill type flow regime, determine the reasonability of Design of Runner System, and by adjusting running gate system parameter and structure, optimizing pouring system, make liquid metal filling process reach perfect condition, avoid the casting flaw producing because Design of Runner System is unreasonable;
2. the present invention directly observes, more reliable compared with computer simulation; Safer, more convenient compared with x-ray observation cavity filling process.
3. instrument and equipment of the present invention is simple, and use cost is low.
