A kind of precision castings evaporative pattern wax melting pool structure and its wax melting method
【Technical field】
The present invention relates to a kind of casting wax pond, more particularly, to a kind of precision castings evaporative pattern wax melting pool structure and its wax melting
Method.
【Background technology】
It is known, in the structural member of casting field, lost-wax process is used mostly, and lost-wax casting technical principle originates from
China's Shang dynasty burns mistake method, and this technology is gradually withered away after occurring without model line lost-wax process.Lost-wax process is the bronze in ancient times etc.
The casting method of metal implements.Way is that the model of casting is made with beeswax, then with other refractory material fill loam core and
Apply into outer model.After heated baking, all fusing is lost in wax-pattern, whole cast model is become ghost.Pour liquation inside again, just
Cast implements.There can be the effect of hollow out with exquisitely carved with the implements of lost-wax process casting.Lost-wax process, there is long go through in China
History, also widely used in modern industry, current wax melting pond is a square pond, first by the wax with molding sand housing during use
Mould is put into pond, then injects hot water in pond, after band wax-pattern dissolves, start to collect the wax stone on top, discharge water after take out molding sand
Housing, this technique not only wastes time and energy, and work efficiency is extremely low.
【The content of the invention】
In order to overcome the shortcomings of in background technology, the present invention discloses a kind of precision castings evaporative pattern wax melting pool structure and its wax melting
Method, the wax fast melt in molding sand housing is made using the heater in wax melting bottom of pond portion, and the wax liquor after thawing is collected by waxing scraper
In wax recovery pond, the purpose being rapidly separated of wax in molding sand housing is realized.

Step 2;
Connect previous step and utilize crane;Or overhead traveling crane;Or any suspender of hoist slings net cage, is then put into net cage and melts
Filter top in wax pond, and the molding sand housing in net cage is submerged in water;
Step 3;
Connect previous step to heat the water in wax melting pond using heater, the wax liquor in molding sand housing is all overflow by hot water
Go out and swim on the water surface in wax melting pond;
Step 4;
Meet the people of previous step two and drive waxing scraper using handle before and after wax melting pond, will using waxing scraper by wax melting pond side
The wax liquor of wax melting pond internal upper part floating pushes to wax recovery pond side, and wax liquor will pass through the wall close to wax recovery pond side parapet
Upper end enters in wax recovery pond, and the waxing scraper is placed motionless;
Step 5;
Connect previous step and net cage is hung out into wax melting pond using suspender, then another batch of net cage for being put into molding sand housing is put into and melted
Wax pond simultaneously repeats operation according to abovementioned steps.
The wax melting method of described precision castings evaporative pattern, the water described in step 2 in wax melting pond are less than setting height
When, appropriate water is added in wax melting pond.
The wax melting method of described precision castings evaporative pattern, the wax liquor described in step 4 in wax recovery pond reach a certain amount of
When, the wax liquor in wax recovery pond is taken out standby.
Due to using technical scheme as described above, the present invention has the advantages that:
Precision castings evaporative pattern wax melting pool structure of the present invention and its wax melting method, utilize the heater in wax melting bottom of pond portion
Make the wax fast melt in molding sand housing, the wax liquor after thawing is collected in wax recovery pond by waxing scraper, realizes molding sand housing
Interior wax is rapidly separated;The present invention realizes the purpose of batch jobs;By the implementation of the present invention, prior art is effectively overcome
Waste time and energy, the drawbacks of work efficiency is extremely low;The present invention is reasonable in design, time saving and energy saving, and wax melting efficiency is greatly improved.
