Abstract
The invention discloses a casting pouring process method. The casting pouring process method includes the following steps: (1) coating are prepared; (2) the prepared coatings are contained in a spraying gun for preparation; (3) pre-heating, coating spraying and cleaning are carried out on a die; (4) a casting ladle is cleaned, wherein oxide and sundries on the surface of the casting ladle are mainly cleaned; (5) the die is closed and firmly fastened; (6) casting molding is achieved. By means of the mode, the casting pouring process method has the advantages that cast castings are free of casting defects on the appearance, internal texture is relatively compact, the casting degree can be greatly improved, and the hardness of insides and outsides of the castings trends to be coincident; meanwhile, accidents can be effectively prevented from happening in the pouring process.
Description
Technical field
The present invention relates to machine casting field, particularly relate to a kind of foundry goods casting process method.
Background technology
Entered for 20th century, the development speed of casting is very fast, and one of its key factor is the progress of product technology, requires that the various mechanical and physical performance of foundry goods is better, still has good machining property simultaneously; Another reason is mechanical industry itself and other industrial development as chemical industry, instrument etc., creates favourable material conditions to foundry industry.
Accessory size and the accommodation of weight of casting are very wide, and metal species is restricted hardly; Part, while having common mechanical performance, also has the combination properties such as wear-resisting, corrosion-resistant, shock-absorbing, be other metal forming methods as forged, rolling, weld, punching etc. do not accomplish.Therefore in machine-building with casting method produce blank part, quantity and tonnage are still so far maximum
Though foundry goods part has many merits, but foundry goods easily producing pore when casting, being mingled with, causing casting quality poor, cannot reach production requirement.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of foundry goods casting process method, casting casting of appearance of cast is out without casting flaw, inherence is organized dense, and foundry goods degree can be increased substantially, hardness inside and outside foundry goods is reached unanimity, can effectively prevent from, in casting cycle, security incident occurs simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of foundry goods casting process method, comprise the steps:
Step one, coating configure, and described coating configuration comprises following composition: sodium metasilicate, talcum powder, zinc oxide, kaolin, graphite and warm water, by above each composition according to certain ratio mixed configuration;
Step 2, the coating configured fully to be stirred, to be mixed evenly after filter with 450 object screen clothes, then by stand-by for the coating loading spray gun filtered;
Step 3, carry out preheating to mould, preheat temperature, 150 ~ 200 DEG C of rooms, then carries out spray coating to mold cavity, has not allowed pit to exist during spary, employing abrasive jet cleaning after spary completes, and the die cavity inside after cleaning has allowed any residue;
Step 4, cleaning casting ladle, main cleaning casting ladle oxide on surface and foreign material, be then heated to 120 ~ 180 DEG C to casting ladle and carry out coating application, again dry casting ladle after coating application;
Step 5, to be got togather by mould, and clamp interface position by jaws, when ensureing casting, liquid can not flow out;
Step 6, pour liquid used for casting into casting ladle, first by mold tilt about 65 degree, then the liquid in casting ladle is slowly poured in mould, follow when pouring liquid into first slow, in fast, rear slow principle carry out, cast while the slow level that mould is returned, till mould dead head must being full of, simultaneously ensure casting must in 2 points in complete.
In the present invention's preferred embodiments, in described step one, coating configures the percentage of each composition and is: sodium metasilicate 10 ~ 15%, talcum powder 2 ~ 5%, zinc oxide 1 ~ 1.5%, kaolin 0.5 ~ 1%, graphite 0.5 ~ 1%, all the other are water.
In the present invention's preferred embodiments, be graphite to the coating of casting ladle brushing in described step 4.
In the present invention's preferred embodiments, in described step 6, cast temperature controls between 950 ~ 1050 DEG C, and casting rate is 6 ~ 9 kg/s.
The invention has the beneficial effects as follows: a kind of foundry goods casting process of the present invention method, casting casting of appearance of cast is out without casting flaw, and inherence is organized dense, and can increase substantially foundry goods degree, hardness inside and outside foundry goods is reached unanimity, can effectively prevent from, in casting cycle, security incident occurs simultaneously.
