Abstract
Bowl-shape drainage screen is used in a kind of aluminum alloy wheel of vehicle casting, this drainage screen is bowl-shape, bowl bottom has the round boss of height 3.0 ~ 5.0, and this boss can play the effect of spreader Yu drainage screen strong fix in casting matched moulds process, it can be ensured that will not be filled partially at aluminum liquid filling type process drainage screen; Drainage screen height is 20 ~ 25, and this height can ensure that spreader tightly withstands drainage screen, it is prevented that fill inclined drainage screen because of the constantly corrosion of spreader; This drainage screen the rim of a bowl edge flanging, flanging height is 3.0～5.0, it is simple to drainage screen is placed in ferrum sprue bush by operator smoothly; Drainage screen mesh spacing 0.2 ~ 0.4mm, hole count is 100 ~ 120 orders; Drainage screen the rim of a bowl diameter is at ￠ 35～60; It is suitable for the casting of the aluminum vehicle wheel that centre bore is ￠ 55 to ￠ 120. Compare with existing drainage screen, this drainage screen have easy to use, intensity is high, stability is high, filter, low cost and other advantages.
Description
Technical field
The present invention relates to aluminum alloy wheel of vehicle casting field, relate in particular to a kind of aluminum alloy wheel of vehicle casting and use bowl-shape drainage screen.
Background technology
Low pressure casting is a kind of production technology being widely used in the fields such as automobile, textile machine, Aero-Space, and this technique, between gravitational casting and compression casting, has advantages such as filling type balance, high, the plastic various casting molds of using rate of metal. At present in aluminum alloy wheel of vehicle forging type, there is more than 80% employing low pressure casting molding. In aluminum vehicle wheel low pressure casting process, melted metal liquid is filled type to each position of mould from low pressure casting machine holding furnace through stalk by casting system, aluminum liquid after solidification falls back to holding furnace again, this casting mode will necessarily bring mold cavity without the field trash fully removed by original in aluminum liquid, therefore at the vitals that the drainage screen emitting port part setting is indispensable in guarantee low pressure casting quality. The drainage screen that aluminum current wheel industry uses has foam ceramic filter, fibrous filter net and three kinds of materials of ferrum drainage screen, though foam ceramic filter and fibrous filter net have many advantages, but owing to material problem is easily broken and rushes partially thus drainage screen brings into foundry goods is non-emits port part, thus forming bigger slag inclusion in blank, it is often possible to cause scrapping of product; Though and ferrum net ratio is stronger, but existing ferrum drainage screen is shallow circle, namely workman is careless slightly in operation can put partially, thus affecting filter effect; This shallow circular filter sieve bottom and spreader coordinate not tight, and in casting process, the constantly corrosion along with spreader there will be the increasingly severe problem filling inclined drainage screen, it is seen then that though drainage screen is the appendicle in foundry goods, has important impact to producing.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, innovating a kind of can realize coordinating thus improving the drainage screen of filter effect more closely with spreader, specifically bowl-shape drainage screen is used in a kind of aluminum alloy wheel of vehicle casting.
The technical scheme realizing object above is: bowl-shape drainage screen is used in a kind of aluminum alloy wheel of vehicle casting, this drainage screen be common iron wire net through mould punching molding, cost is lower than foam ceramic filter. This drainage screen is bowl-shape, and bowl bottom has the round boss of height 3.0 ~ 5.0, and this boss can play the effect of spreader Yu drainage screen strong fix in casting matched moulds process, it can be ensured that will not be filled partially at aluminum liquid filling type process drainage screen; Drainage screen height is 20 ~ 25, and this height can ensure that spreader tightly withstands drainage screen, it is prevented that fill inclined drainage screen because of the constantly corrosion of spreader; This drainage screen the rim of a bowl edge flanging, flanging height is 3.0～5.0, it is simple to drainage screen is placed in ferrum sprue bush by operator smoothly; Drainage screen mesh spacing 0.2 ~ 0.4mm, hole count is 100 ~ 120 orders; Drainage screen the rim of a bowl diameter is at Φ 35～60; It is suitable for the casting of the aluminum vehicle wheel that centre bore is Φ 55 to Φ 120. Compare with existing drainage screen, this drainage screen have easy to use, intensity is high, stability is high, filter, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is the bowl-shape drainage screen of the present invention.
Fig. 2 is the cooperation figure of the bowl-shape drainage screen of the present invention and spreader.
Detailed description of the invention
For 225-1790 drainage screen, as shown in Figures 1 and 2, bowl-shape drainage screen is used in a kind of aluminum alloy wheel of vehicle casting, this drainage screen 3 is made up of wire gauze, in bowl-shape, having round boss 1, have flanging 2 at bowl-shape drainage screen edge bottom this bowl-shape drainage screen, this round boss height is 4.0, this boss can play the effect of spreader Yu drainage screen strong fix in casting matched moulds process, and round boss will not be filled partially at aluminum liquid filling type process drainage screen; This drainage screen the rim of a bowl edge flanging height 3.0, it is simple to drainage screen is placed in ferrum sprue bush by operator smoothly; Drainage screen height is 20, and this height can ensure that spreader tightly withstands drainage screen, it is prevented that fill inclined drainage screen because of the constantly corrosion of spreader; Drainage screen mesh spacing 0.3mm, hole count is 120 orders, and the rim of a bowl diameter is at Φ 45; Adapt to the casting of the aluminum vehicle wheel that centre bore is Φ 55 to Φ 120. Drainage screen 3 is put into during use the inside of ferrum cast gate 5, and after matched moulds, spreader 4 tightly withstands the round boss 1 of drainage screen 3. Compare with existing drainage screen, this drainage screen have easy to use, intensity is high, stability is high, filter, low cost and other advantages.
