Abstract
The invention belongs to the field of metal casting and in particular relates to magnesium alloy low-pressure casting equipment. The magnesium alloy low-pressure casting equipment comprises a die rack, and an upper die and a lower die which are arranged on the die rack, wherein the upper die is driven by a hydraulic cylinder; the lower die is fixed on the die rack; the lower die is connected with a liquid filling pipe; and the tail end of the liquid filling pipe stretches into a sealed container with magnesium liquid. The magnesium alloy low-pressure casting equipment is characterized in that a casting ladle is arranged at the tail end of the liquid filling pipe; a one-way valve is mounted at a liquid inlet at the bottom of the casting ladle; an air inlet pipe connected with an air compressor is mounted at the top end of the casting ladle; an electric heating wire is wound on the liquid filling pipe; and a heating bar is arranged in the casting ladle. The magnesium alloy low-pressure casting equipment is reasonable in structure; the casting ladle is arranged at the tail end of the liquid filling pipe, so the contact area of the magnesium liquid and the air can be reduced, the working region is reduced from a big crucible to a small casting ladle with high sealing property, and the potential safety hazard is reduced; and the electric heating wire and the heating bar are provided, so that the magnesium liquid does not solidify quickly, blockage of the liquid filling pipe caused by the solidification of the magnesium liquid is avoided and the normal operation of production is guaranteed.
Description
Technical field
The present invention relates to a kind of magnesium alloy low-pressure casting equipment, belong to field of metal casting technology.
Background technology
At present, along with the requirement of automotive light weight technology is more and more higher, the more and more aluminum alloy cast forging pieces that use of automobile industry.Now to utilize wider forging type as low pressure casting and die casting.Compare with the latter, low pressure casting has that the casting utilization rate is very high, internal flaw is few, can use the sand manufacturing mold core, be subjected to the advantages such as the impact of operator's qualification is less, but traditional low-pressure die casting plant only is confined to aluminium alloy casting, has limited the application of magnesium alloy in the low pressure casting product that density is less, intensity is higher.
For making more high performance product, those skilled in the art have gone out to meet the equipment of magnesium alloy low-pressure casting by a large amount of experimental design, make the aluminium liquid in the airtight container enter mould molding by the topping up pipe by air compressor machine compressed air, but when using this kind equipment to carry out Mg alloy castings production, but be difficult to moulding.Reason is as follows: 1, when using air to pressurize, the liquid level partial pressure of oxygen increases, and magnesium alloy very easily is combined with oxygen, easily produces the danger that is difficult to predict; 2, the calorific potential of magnesium is far below aluminium, easily solidifies during transmission in the topping up pipe and causes the obstruction of topping up pipe.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of rational in infrastructure, security performance is high and prevent the magnesium alloy low-pressure casting equipment that magnesium liquid solidifies.
Magnesium alloy low-pressure casting equipment of the present invention, comprise die frame and the upper die and lower die that are installed on the die frame, patrix is by Driven by Hydraulic Cylinder, and counterdie is fixed on the die frame, and counterdie connects the topping up pipe, topping up pipe end stretches in the airtight container that fills magnesium liquid, the end of topping up pipe is set up casting ladle, and one-way cock is installed at the inlet place of casting ladle inner bottom part, and the air inlet pipe that is connected with air compressor is installed on the casting ladle top, twine heating wire on the topping up pipe, the built-in heating rod of casting ladle.
Operation principle and process:
After smelting is finished, this equipment is installed, magnesium liquid enters casting ladle by the pressure of self.Opening device, heating wire and heating rod work heat up to the magnesium liquid in topping up pipe and the casting ladle, prevent the magnesium liquid cooling but.Open the breather valve of air compressor, the casting ladle internal pressure increases, and the one-way cock of casting ladle inner bottom part is closed, and magnesium liquid enters counterdie by the topping up pipe, and intake valve is closed in moulding.In casting process, because air and magnesium liquid contact area are less, and spatial closure is better, can not produce dangerous in casting process; The existence of heating wire, heating rod also causes damp production so that magnesium liquid can not solidify rapidly.
The beneficial effect that the present invention compared with prior art has is:
This magnesium alloy low-pressure casting device structure is reasonable, by setting up casting ladle at topping up pipe end, can reduce the contact area of magnesium liquid and air, the working region is decreased to casting ladle than the trifle better tightness from larger crucible, reduce potential safety hazard, by heating wire and heating rod are set, magnesium liquid can not solidified rapidly, prevent magnesium liquid frozen plug topping up pipe, guaranteed the normal operation of producing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, hydraulic cylinder; 2, die frame; 3, patrix; 4, counterdie; 5, air inlet pipe; 6, air compressor; 7, airtight container; 8, casting ladle; 9, one-way cock; 10, heating rod; 11, topping up pipe; 12, heating wire; 13, Hydraulic Station.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
As shown in Figure 1, magnesium alloy low-pressure casting equipment, comprise die frame 2 and the patrix 3 that is installed on the die frame 2, counterdie 4, patrix 3 is driven by hydraulic cylinder 1, hydraulic cylinder 1 connects Hydraulic Station 13, lower, 4 are fixed on the die frame 2, counterdie 4 connects topping up pipe 11, and topping up pipe 11 ends stretch in the airtight container 7 that fills magnesium liquid, and the end of topping up pipe 11 is set up casting ladle 8, install in the one-way cock 9(present embodiment and adopt a tungsten alloy ball at the inlet place of casting ladle 8 inner bottom parts), the air inlet pipe 5 that is connected with air compressor 6 is installed on casting ladle 8 tops, twines heating wire 12, casting ladle 8 built-in heating rods 10 on the topping up pipe 11.
Operation principle and process:
After smelting is finished, this equipment is installed, magnesium liquid enters casting ladle 8 by the pressure of self.Opening device, heating wire 12 and heating rod 10 work heat up to the magnesium liquid in topping up pipe 11 and the casting ladle 8, prevent the magnesium liquid cooling but.Open the intake valve of air compressor 6, casting ladle 8 internal pressures increase, and tungsten alloy ball is with the inlet sealing (being that one-way cock 9 is closed) of casting ladle, and magnesium liquid enters counterdie 4 by topping up pipe 11, and intake valve is closed in moulding.In casting process, because of casting ladle 8 Airs and magnesium liquid contact area is less and spatial closure is better, can in casting process, not produce dangerous; The existence of heating wire 12, heating rod 10 also so that magnesium liquid can not solidify rapidly, prevents magnesium liquid frozen plug topping up pipe 11, has guaranteed the normal operation of producing.After closing intake valve, one-way cock 9 is opened under the pressure-acting of magnesium liquid self, and magnesium liquid enters casting ladle 8, and is ready for cast next time.
