Abstract
The invention relates to a casting method of aluminum alloy rod parts and casting equipment for realizing the same. The casting method is characterized in that liquid supply is carried out under the liquid level and a metal liquid is cooled and solidified from bottom to top. The casting equipment comprises a mould and a suspended funnelform ladle, wherein the mould is arranged with a mould cavity opening vertically upward; a filter screen is padded at the bottom of the inner cavity of the ladle; the inner cavity of the ladle and a funnel opening are partitioned by the filter screen; the meshes of the filter screen are fine, thereby temporarily storing molten metal foams; the funnel opening of the ladle is connected with a long and thin liquid conveying pipe for guiding and conveying molten metal; the liquid conveying pipe is inserted into the mould cavity of the mould and the bottom end of the liquid conveying pipe is close to the bottom of the mould cavity; the molten metal is injected to the mould cavity through the liquid conveying pipe; the liquid conveying pipe raises gradually relative to the bottom of the mould cavity on the premise that the bottom liquid outlet of the liquid conveying pipe is positioned below the liquid level after the molten metal overflows the bottom of the liquid conveying pipe, and the liquid level gradually raises and is sequentially cooled and solidified towards the top. By utilizing the casting method, the defects of poor quality, low molded product percent of pass and high energy consumption existing in the traditional casting method are overcome, and low energy consumption, high part percent of pass and good quality are realized.
Description
Technical field
The invention belongs to the aluminum alloy part casting technology field, especially relevant with the equipment of this method of realization with a kind of casting method of aluminium alloy bars class part.
Background technology
Adopt casting to form as rods and bars of aluminium alloy class parts such as damper of motorcycle sleeves, form casting mold cavity behind the casting mould matched moulds since to cast part be the bar class, so the die cavity axial length is bigger.Existing rods and bars of aluminium alloy class part casting method commonly used has two kinds, a kind of is inclination top casting casting, mould is tilted, Al-alloy metal liquid is directly poured into from the die cavity top, it is vertical with mould that molten metal is full of behind the die cavity, molten metal cools off back taking-up just becoming part blank in die cavity, this casting method is poured in the die cavity process because oxidation can produce oxide skin at molten metal, the area of oxide skin is bigger, under oxide skin, be easy to generate and accumulate bubble, influence product quality, when piece surface shape more complicated, local die cavity occurring easily can't the filling phenomenon, causes product imperfect; Another kind is that cavity lateral is injected casting, offer a plurality of road junctions of watering at the sidewall of mould, molten metal injects from the running channel on these sidewalls and is full of die cavity, in the process of casting, water road junction one side owing to there is molten metal constantly to inject, make that the vertical temperature difference of die cavity is bigger, cooling velocity is variant, then the blank quality uniformity of moulding is poor, and the existence unit of the making required molten metal of blank of running channel increases, and has also just strengthened the energy consumption of deposite metal.
Summary of the invention
Purpose of the present invention is exactly the technical problem that exists at the casting method of above-mentioned aluminium alloy bars class part, provides that a kind of energy consumption is low, the casting method of the product percent of pass height of moulding, the measured aluminium alloy bars class of matter part and realize the Casting Equipment of this method.For this reason, the present invention is by the following technical solutions:
A kind of casting method of aluminium alloy bars class part, it is characterized in that: earlier with required quantitative Al-alloy metal liquid temporary bubble of eliminating in a container, use a less woven hose of diameter to connect described container bottom and insert mold cavity bottom, by woven hose molten metal is injected die cavity, molten metal covers woven hose bottom liquid outlet and forms feed flow under the liquid, woven hose with the bottom liquid outlet be positioned under the molten metal liquid level be prerequisite with respect to cavity bottom lifting gradually, the molten metal liquid level rise gradually with respect to cavity bottom and from cavity bottom to top order cooled and solidified.
A kind of Casting Equipment that realizes above-mentioned casting method, comprise mould with die cavity, mould vertically is provided with up with the die cavity oral area, it is characterized in that: described Casting Equipment also comprises the casting ladle of suspension, and this casting ladle is infundibulate, and casting ladle intracavity bottom pad is provided with filter screen, filter screen is separated the inner chamber and the bell mouth of casting ladle, the filter screen mesh is fine and closely woven, and the bell mouth of casting ladle is connected with elongated woven hose and is used for water conservancy diversion and transferring metal liquid, and woven hose inserts the close cavity bottom of mold cavity and its bottom.
When present device is used, quantitative molten metal is poured casting ladle into, mesh is fine and closely woven at normal temperatures owing to filter screen, molten metal is intercepted and can't pass through by filter screen, be temporary in casting ladle, bubble in the temporary time period inner metal liquid will be overflowed from molten metal and be reached the froth breaking purpose, the molten metal of high temperature heats filter screen, make the expansion of filter screen mesh, molten metal passes through from the filter screen mesh, flows into woven hose, because woven hose is an elongated tubular, molten metal when the woven hose top flows to the bottom with the air emptying the woven hose, molten metal flows into the mold cavity bottom from woven hose, covers woven hose bottom liquid outlet very soon, and follow-up molten metal has just been flowed under the molten metal liquid level in the mold cavity, subsequently, lifting casting band rises gradually with woven hose gradually, but the bottom liquid outlet of woven hose is positioned under the molten metal liquid level of die cavity all the time, and woven hose liquid outlet rising by the time arrives the die cavity top, molten metal in the casting ladle all flows into die cavity, and woven hose is lifted away from mold cavity; In the process that woven hose rises, molten metal to die cavity top order cooled and solidified, is opened the blank that mould takes out moulding from cavity bottom after solidifying fully, finishes a part casting.
As to technique scheme further replenish and perfect, the present invention also comprises following supplementary technology scheme:
Described mould is fixedly installed on the frame.
Described Casting Equipment comprises that also lifting apparatus is used for the lifting casting ladle.
Described lifting apparatus is a cylinder, and cylinder block is fixed, and cylinder piston is connected with casting ladle.
Described lifting apparatus can also be an oil cylinder, and cylinder block is fixed, and oil cylinder piston is connected with casting ladle.
Described frame is provided with horizontal pushing mechanism and is used for fixing mould.
Described frame is provided with lowering or hoisting gear, is used for the lifting mould, realizes that the woven hose liquid outlet rises gradually with respect to the mold cavity bottom.
The present invention adopt feed flow under the liquid level, molten metal from bottom to top the order cooled and solidified casting method and realize the Casting Equipment of this method, have following beneficial effect:
1, eliminates the bubble in the casting cycle, eliminated the gas cinder hole, improved surface quality;
2, molten metal can cool off and to cool off cross section little in proper order, solidifies high conformity, has improved product quality and intensity;
3, cancel running channel and head piece, saved the required molten metal of single part casting, reduced the energy consumption that molten metal melts;
4, can fill the casting mould die cavity of complex surface part, improve product percent of pass.
5, can realize the automation casting, improve product and make efficient.
