Description

Technical Field

[0001] The utility model relates to the technical field of low-pressure casting, in particular to an air intake filtering mechanism used for low-pressure casting. Background Art

[0002] Low-pressure casting is a method of filling a sealed insulation furnace with dry air at a certain pressure, so that the liquid metal in the furnace fills the cavity from the bottom of the cavity under pressure to form a casting. Because the pressure used is relatively low, it is called low-pressure casting.

[0003] The current low-pressure casting machine cannot filter the low-pressure gas entering during casting, and it directly enters the equipment, so that impurities will follow the low-pressure gas into the mold, which will affect the quality of the finished mold. At the same time, it is difficult to remove the parts after completion. Workers may easily burn their hands when grabbing them, and need to wait for cooling by themselves. The cooling time is also long, which will reduce work efficiency. Utility Model Content

[0023] The inner cavity of the heating device 2 is provided with three heating wires 3 at equal distances.

[0024] In this embodiment, the heating device 2 is heated by three heating wires 3 to form a high temperature, which can heat the molten aluminum in the inner cavity of the liquid storage box 4, ensuring that the molten aluminum in the liquid storage box 4 is always in a non-solidified state, thereby preventing the molten aluminum from solidifying and being unable to be used normally.

[0025] Among them, an air outlet pipe 8 is arranged on the top of the gas compression device 7, and an air pump 9 is arranged in the middle of the air outlet pipe 8.

[0026] In this embodiment, low-pressure gas is generated by the gas compression device 7, and then the low-pressure gas in the gas compression device 7 is extracted through the air outlet pipe 8 by the air pump 9, transported to the bottom position of the inner cavity of the connecting seat 1, and enters the liquid storage box 4.

[0027] Among them, a filter screen 10 and activated carbon material are arranged on the left side of the bottom of the inner cavity of the connecting seat 1.

[0028] In this embodiment, the low-pressure gas can be filtered when it is blown out from the outlet pipe 8 through the filter mesh 10 to prevent the presence of impurities and dust. At the same time, the activated carbon material can adsorb the fine impurities in the gas, thereby doubly filtering and purifying the low-pressure gas and improving the quality of the low-pressure gas.

[0029] The upper mold 15 is fixedly installed at the bottom of the output end of the hydraulic cylinder 14 .

[0030] In this embodiment, the output end of the hydraulic cylinder 14 can drive the upper mold 15 to move downward and merge with the lower mold 12, and at the same time, can drive the upper mold 15 to move upward and separate from the lower mold 12, thereby facilitating the user to combine the casting and the separation of the casting to remove the mold, effectively improving the convenience of the user.

[0032] In this embodiment, the liquid inlet 13 can allow the liquid storage box 4 to be subjected to low pressure and the molten aluminum therein to be delivered to the inner cavity of the lower die 12 through the liquid delivery pipe 6 to achieve a forging effect.

[0033] The electric motors 16 are arranged on both sides of the connecting seat 1 , and the outer rings of the output shafts of the electric motors 16 are fitted with fan blades 17 .

[0034] In this embodiment, the output shafts of the two electric motors 16 drive the fan blades 17 to rotate, blowing air to dissipate heat from the cast mold, allowing the mold to cool quickly, thereby reducing the cooling time and improving the work efficiency of the user.

[0035] Working principle: When in use, firstly, aluminum liquid is injected into the liquid storage box 4 through the liquid inlet pipe 5, and then the heating device 2 is heated by the three heating wires 3 to form a high temperature, which can heat the aluminum liquid in the inner cavity of the liquid storage box 4 to ensure that the aluminum liquid in the liquid storage box 4 is not in a solidified state. Then, the upper mold 15 is driven downward by the output end of the hydraulic cylinder 14 to be integrated with the lower mold 12. At this time, low-pressure gas is generated by the gas compression device 7, and then the low-pressure gas in the gas compression device 7 is extracted by the air pump 9 through the air outlet pipe 8 and transported to the bottom position of the inner cavity of the connecting seat 1, and enters the storage Low pressure is formed in the liquid box 4, so that the molten aluminum moves upward through the liquid feeding pipe 6. The liquid inlet 13 can make the liquid storage box 4 be subjected to low pressure and the molten aluminum therein be sent into the inner cavity of the lower mold 12 through the liquid feeding pipe 6 to cast the mold. After the casting is completed, the upper mold 15 is driven to move upward and separate from the lower mold 12 through the output end of the hydraulic cylinder 14. At this time, the output shafts of the two electric motors 16 are driven by the fan blades 17 to rotate, and the cast mold is blown and cooled, so that the mold is cooled quickly, so that the user can combine the casting and the separation of the casting completion to remove the mold.
