When gas be not easy to be involved in, its forming temperature is low, and die life length, deformation drag is small, and production efficiency is high；High-pressure during shaping
The metal that has solidified is set to produce retrospective deformation, it is not solidified to continue solidification under high pressure thus product shrinkage cavity shrinkage porosity is few, tissue causes
Close, mechanical performance is higher than common casting close to forging, thermally processable, high without riser feeding, rate of metal.It is adapted to
It is thin, heavy section casting to produce the shaping for also being adapted for the wider any alloy material in various crystallization temperature intervals.
Although the casting produced with semi-solid forming technology has many good qualities, the preparation method of slurry is also very much,
The continuous of inexpensive high-quality pulp is prepared, preserved, conveying always problem, seriously restricts the popularization and application of the technology.
The content of the invention
The present invention is in order to solve the above technical problems, provide a kind of constant current for continuous conveying aluminium alloy semi-solid slurry
Pump, for conveying aluminum liquid, including driving mechanism and molten aluminum conveying mechanism, the molten aluminum conveying mechanism includes rotor and stator, institute

The infusion portion that son is placed in execution molten aluminum conveying function inside slurry is equipped with molten aluminum accommodating chamber, and the rotor in the molten aluminum accommodating chamber is set
There is arc blade, the stator side wall is equipped with the liquid sucting port and leakage fluid dram connected with molten aluminum accommodating chamber, and the leakage fluid dram is connected with
Feed tube.
Further, the liquid sucting port is placed on leakage fluid dram outside 45 degree of angles away from rotor and stator points of tangency.
Further, high-temperature resistant seal ring and gasket are equipped between the rotor and stator on the molten aluminum accommodating chamber top.
Further, the high-temperature resistant seal ring is U-shaped, V-arrangement or square high-temperature resistant seal ring, and the gasket is square pad
Piece.
Further, the rotor, stator and arc blade are graphite, ceramics or high-temperature resistant composite material.
Further, the driving mechanism includes motor, the first runner, the second runner, transmission belt and shaft, motor it is defeated
Outlet connects the first runner, and transmission belt connects the second runner respectively, and the second runner is connected with shaft, and shaft passes through bearing and rotor
Top is fixedly connected.Motor operations drive the first runner to rotate, so as to transmit power to shaft by transmission belt, revolve shaft
Turn, and then drive the arc blade relative stator of rotor to rotate.
The present invention use volume pump, its persevering discharge characteristic thus when the section sudden expansion of liquid metal fill level,
Its filling velocity reduces naturally, this liquid level pressurizing control system for just overcoming conventional pressure to control is unable to lacking for controlled level flow velocity
Point, improves the internal quality of casting, and can cancel the operation that each casting places filter screen.Aluminium alloy semi-solid New Forming Process
When die cavity is full of by the characteristic pumped cause can in time, be automatically performed the very big pressure surge of amplitude, this is to improving aluminium alloy half
The inherent quality meaning of formed solid product part is very huge.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structure diagram of the constant flow pump for continuous conveying aluminium alloy semi-solid slurry of the present invention.
Embodiment
Referring to Fig. 1, it is to be used for continuous conveying aluminium alloy semi-solid slurry as one kind of highly preferred embodiment of the present invention
Constant flow pump, for conveying aluminum liquid, including driving mechanism and molten aluminum conveying mechanism, molten aluminum conveying mechanism includes rotor 8 and stator
1,1 inner hollow of stator, rotor 8 is arranged on inside stator 1, and driving mechanism drives rotor 8 in 1 internal rotating of stator.Stator 1 is placed in
The infusion portion that molten aluminum conveying function is performed inside slurry is equipped with molten aluminum accommodating chamber, and the rotor 8 in the molten aluminum accommodating chamber is equipped with arc
Shape blade, 1 side wall of stator are equipped with the liquid sucting port and leakage fluid dram connected with molten aluminum accommodating chamber, and leakage fluid dram is connected with feed tube.Imbibition
Mouth is placed on leakage fluid dram outside 45 degree of angles away from rotor 8 and 1 points of tangency of stator.The rotor 8 on molten aluminum accommodating chamber top and stator 1
Between be equipped with high-temperature resistant seal ring 9 and gasket 11.High-temperature resistant seal ring 9 is U-shaped, V-arrangement or square high-temperature resistant seal ring, gasket 11
For square washer.Driving mechanism includes motor 7, the first runner 6, the second runner 4, transmission belt 5 and shaft 3, the output terminal of motor 7
Connect the first runner 6, transmission belt 5 connects the second runner 6 respectively, and the second runner 4 is connected with shaft 3, shaft 3 by bearing 2 with
