Description

Technical Field

[0002] Automobile lightweighting can improve the fuel efficiency of fuel vehicles and the cruising range of new energy vehicles. The density of aluminum alloy is only 1 / 3 of that of steel, and it has a high specific strength, making it the preferred material for lightweighting. Die-casting is a precision casting method that uses high pressure to force molten metal into a metal mold with a complex shape. For components such as aluminum alloy automobile wheels and frames that are expected to be produced with higher-strength and impact-resistant materials, it has more positive significance. The Chinese patent discloses an aluminum alloy die-casting machine, with the application number: 202320641652.8. This die-casting machine can cool the liquid aluminum alloy in the mold in all directions, reduce the cooling and solidification time, improve work efficiency, and facilitate demolding;

[0003] However, in the current aluminum alloy die-casting system, during the die-casting process, the energy dissipated during the die-casting process cannot be effectively converted and utilized. A large amount of energy is consumed during the die-casting and pressure-holding processes of aluminum alloy molten slurry, resulting in poor energy-saving effects. Moreover, it cannot stably and efficiently provide sufficient pressure for die-casting work, resulting in poor die-casting effects. At the same time, it is necessary to rely on a high-power external electrical pressure device, resulting in a high equipment cost of the die-casting system, which is not conducive to the popularization and use of the system and also affects economic benefits.

Coupled with the flow-limiting and guiding effects of the transfer pipe, the central control box, the balance block, the through hole, the delivery pipe, and the branch pipe, the driving force provided by the wind wheel, the impeller, and the turbine can be secondarily converted and utilized.

[0028] Through the cooperation of the transfer pipe, the central control box, the two-part plate, the connecting rod, the balance block, the movable block, the through hole, the through groove, the pressure relief port, the delivery pipe, and the branch pipe, a pressure control structure can be constructed to limit the clamping force, the die casting pressure, and the reset pressure, realizing the dynamic control of the mold closing work, the clamping work, the die casting work, the pressure holding work, and the mold opening and reset work during the die casting process, greatly enhancing the connection stability and the cooperation smoothness among various links, making the die casting work more smooth and efficient. Through the solenoid valve, the control boundary line of die casting work can be further improved. Through the cooperation of the diversion box, the same-pressure ring, the air valve, and the pressure gauge, the adjustment convenience of system parameters can be greatly improved, indirectly enhancing the die casting efficiency.

[0029] In summary, the present system integrates functions of raw material melting, mold closing, clamping, die casting, pressure holding, and mold opening, and can recycle the heat dissipated during the raw material melting process, greatly enhancing the energy-saving effect of the system. It can realize die casting work without relying on external electrical pressure driving equipment, greatly reducing the system cost, and can cyclically stack and secondarily amplify the driving force, effectively enhancing the pressure sufficiency and stability of die casting work, reducing the difficulty of obtaining pressure, and simultaneously enhancing the stability of the die casting pressure and the clamping force, making the die casting work more stable and effective.

[0060] Working principle and usage process of the present invention: When die-casting aluminum alloy components using this integrated die-casting system, first place the melting furnace 15 in the working area to be processed, align the top of the furnace barrel 16 with the external feeding device, then clamp the fixed die 13 on the fixed seat 11 and the moving die 14 on the movable seat 12. Subsequently, according to actual needs, inject a refrigerant in a gas-liquid equilibrium state into the partition chamber 219 through the material valve 2191. When selecting the refrigerant, the critical temperature of the refrigerant should be less than the melting temperature of the aluminum alloy to be processed, and a refrigerant with a large expansion rate is preferred. Here, R410A refrigerant is selected;

[0061] Subsequently, under the diversion of the check valve 218, the refrigerant will then enter the vortex box 214 through the conduit 217 and flow back into the partition chamber 219 through the thin tube 216. This is the refrigerant flow path during the die-casting process of the aluminum alloy component, denoted as the refrigerant circuit. After filling the partition chamber 219, the conduit 217, the vortex box 214, and the thin tube 216 with the refrigerant in a gas-liquid equilibrium state, stop the refrigerant filling work;

[0062] Then, inject air into the diversion box 319 through the air valve 321 on the diversion box 319. After the air is injected into the diversion box 319, it will enter the shaft cylinder 301 through the insertion tube 306, press the plug 304, and force the push rod 302 to slide along the shaft cylinder 301 under the push of the plug 304, driving the movable seat 12 away from the fixed seat 11. Here, the air pressure of the injected air can be limited according to the pressure gauge 322 on the diversion box 319, so that the internal air pressure is not less than the minimum air pressure that can drive the displacement of the plug 304. Denote this air pressure as the reset air pressure;

[0063] Subsequently, through the air valve 321 on the drive seat 208, inject air into the cavity connected to the inside of the drive seat 208. After the air is injected into the drive seat 208, it will press the piston 211 inside the corresponding cavity, forcing the pry bar 210 to drive the drive rod 206 to deflect through the connecting plate 209, causing the ball 207 to roll along the drive rod 206 and dragging the push plate 204 along the injection cylinder 201 towards the drive seat 208 side through the bushing 205, making the material tube 203 communicate with the injection cylinder 201. According to the reading of the pressure gauge 322 on the drive seat 208, the air pressure of the injected air can be limited so that the air pressure of the injected air is greater than the reset air pressure. This air pressure is the initial air pressure when driving the fixed die 13 and the moving die 14 to complete the mold closing, and it is also the minimum air pressure during the die-casting process, denoted as the initial air pressure;

[0064] Then, air is injected into the central control box 308 through the air valve 321 on the central control box 308, forcing the balance weight 311 to slide towards the movable block 312 under the action of this air pressure. The movable block 312 is driven to slide synchronously through the connecting rod 310, so that the balance weight 311 abuts against the two-part plate 309. At this time, the through hole 313 is simultaneously communicated with the branch pipe 317 and the conveying pipe 316, and the passage between the pressure relief port 315 and the branch pipe 317 is blocked by the movable block 312. According to the reading of the pressure gauge 322 on the central control box 308, the air pressure for injecting air can be limited, so that the air pressure for injecting air is greater than the initial air pressure. This air pressure is the safety air pressure threshold during the die-casting process and also the maximum air pressure during the die-casting process, denoted as the die-casting air pressure;

[0065] After completing the above installation and debugging work, the coil 17 can be powered on to carry out the die-casting work of aluminum alloy parts. The external feeding device puts aluminum alloy raw materials into the furnace barrel 16. The current flowing through the coil 17 will generate a high-frequency electromagnetic field inside the furnace barrel 16. Then, under electromagnetic induction, the aluminum alloy raw materials put into the furnace barrel 16 will be gradually heated under the action of eddy current until they reach the molten state. Subsequently, the molten slurry will flow into the injection cylinder 201 through the material pipe 203 under the action of gravity. Here, under the conduction of the material pipe 203, a communicating vessel is equivalently formed between the furnace barrel 16 and the injection cylinder 201. Under the action of gravity, the molten slurry will fill the internal cavity of the injection cylinder 201;

[0066] When the aluminum alloy raw materials inside the furnace barrel 16 are melted, the temperature inside the partition chamber 219 will increase synchronously, and finally exceed the critical temperature of the refrigerant, breaking the equilibrium state of the refrigerant inside the partition chamber 219. The refrigerant inside the partition chamber 219 will quickly vaporize and enter the vortex box 214 through the conduit 217 under the action of air pressure, forcing the turbine 225 inside the vortex box 214 to rotate accordingly under its drive. Subsequently, under the traction of the turbine 225, the gaseous refrigerant will enter the thin pipe 216, forcing the air pressure inside the thin pipe 216 to increase, causing the refrigerant inside the thin pipe 216 to quickly liquefy and release heat under the action of pressure. Then, the liquefied refrigerant will flow back into the partition chamber 219 again and vaporize again at the high temperature inside the partition chamber 219, forming a complete refrigerant cycle;

[0067] During the rotation of the turbine 225, it will drive the impeller 224 to rotate synchronously through the coupling 215. Under the traction of the impeller 224, after the external air is filtered by the filter box 2201, it will be drawn into the air box 213 through the air duct 220 and then pressed into the wheel box 212 through the air pipe 221, causing the wind wheel 223 to rotate accordingly under the impact of the air flow. And under the transmission of the coupling 215, it forms a resultant force with the pressure given by the refrigerant to the turbine 225 to drive the turbine 225 to rotate faster with greater force;

[0068] The air flow entering the wheel box 212 here will then be forced through the connecting pipe 222 into the cavity at the top of another piston 211 inside the drive seat 208, causing the air pressure inside this cavity to rise synchronously with the air pressure inside the wheel box 212. For the convenience of description, this cavity is denoted as the energy storage cavity, and the air pressure inside it is the dynamic air pressure. During this process, the resistance received by the wind wheel 223 comes from the dynamic air pressure, while the driving force for driving the wind wheel 223 to rotate is the sum of the dynamic air pressure and the impact pressure of the refrigerant received by the turbine 225, that is, the driving force for driving the wind wheel 223 to rotate is greater than the resistance received by the wind wheel 223, and the wind wheel 223 will perform an accelerating motion;

[0069] Correspondingly, driven by the coupling 215, the impeller 224 and the turbine 225 will also rotate faster, enabling the refrigerant to circulate more rapidly, converting and utilizing the heat dissipated during the melting process of the aluminum alloy raw material more efficiently, forcing the external air flow to be continuously pressed into the energy storage cavity at a faster speed under the traction of the impeller 224, causing the dynamic air pressure to rise rapidly in an additive manner;

[0070] Under the conduction of the transfer pipe 307, the air inside the energy storage cavity will flow into the central control box 308 through the transfer pipe 307. When the dynamic air pressure is greater than the reset air pressure and less than the initial air pressure, it is not sufficient to push the movable block 312 to displace. At this time, the air flow flowing into the central control box 308 will flow into the branch pipe 317, pass through the through hole 313, flow into the same-pressure ring 320 through the delivery pipe 316, and then enter each shaft cylinder 301, flow into the space outside the push rod 302 inside the shaft cylinder 301 through the telescopic pipe 305, offset the reset air pressure, and cause the plug 304 to drag the movable seat 12 close to the fixed seat 11 under pressure, closing the fixed mold 13 and the movable mold 14;

[0071] When the dynamic air pressure is greater than the initial air pressure and less than the die-casting air pressure, the air pressure received at the top of the piston 211 inside the energy storage cavity is sufficient to offset the initial air pressure received at the top of another piston 211. At this time, under the push of the dynamic air pressure, the pry bar 210 will drive the drive rod 206 to deflect in the reverse direction through the connecting plate 209, forcing the push plate 204 to slide towards the fixed seat 11. As the push plate 204 slides, the push plate 204 will cut off the connection between the material pipe 203 and the injection cylinder 201, and press the molten slurry inside the injection cylinder 201 into the mold cavity surrounded by the fixed mold 13 and the movable mold 14 through the injection pipe 202. Here, a lever structure is formed among the drive rod 206, the ball 207, the connecting plate 209, the pry bar 210, and the piston 211, which can further amplify the die-casting pressure and improve the sufficiency of the pressure during the die-casting process;

[0072] However, limited by the die-casting air pressure at this time, the dynamic air pressure still cannot overcome the die-casting air pressure received by the balance block 311 to drive the movable block 312 to slide. That is, at this time, the through hole 313 is still in communication with the branch pipe 317 and the conveying pipe 316 at the same time. The pressure received by the plug 304 will rise synchronously with the dynamic air pressure. That is, the clamping pressure between the fixed seat 11 and the movable seat 12 will rise synchronously with the die-casting pressure applied to the molten slurry by the push plate 204;

[0073] When the dynamic air pressure is greater than the die-casting air pressure, the dynamic air pressure will overcome the die-casting air pressure received by the balance block 311 to drive the movable block 312 to slide. At this time, the through hole 313 is no longer in communication with the branch pipe 317 and the conveying pipe 316. That is, the air pressure value received by the plug 304 will be maintained at the dynamic air pressure value when the movable block 312 slides;

[0074] The through groove 314 will be in communication with the pressure relief port 315 and the branch pipe 317 at the same time. At this time, the air pressed into the central control box 308 by the impeller 224, after entering the branch pipe 317, will pass through the through groove 314 and be discharged through the pressure relief port 315, temporarily suspending the pressure increase process inside the energy storage cavity and keeping the air pressure inside the energy storage cavity in the current state. When the dynamic air pressure is less than the die-casting air pressure, the balance block 311 will drive the movable block 312 to slide toward the transfer pipe 307 side under the drive of the die-casting air pressure, and cut off the connection between the pressure relief port 315 and the branch pipe 317 again, causing the dynamic air pressure to rise again;

[0075] In this way, even if the dynamic air pressure fluctuates near the die-casting air pressure, the push plate 204 will press the molten slurry under the drive of the dynamic air pressure, so that the molten slurry fills the mold cavity surrounded by the fixed mold 13 and the movable mold 14, performs pressure holding, and realizes the auxiliary vibration of the molten slurry;

[0076] After the die-casting work is completed, the solenoid valve 318 can be opened. At this time, the air pressed into the central control box 308 by the impeller 224 will be directly discharged through the solenoid valve 318. At this time, the dynamic air pressure drops suddenly. Without the support of the dynamic air pressure, the movable seat 12 and the movable mold 14 will reset, realizing automatic mold opening. The balance block 311, the movable block 312, and the push plate 204 will also reset, waiting for the next round of die-casting.
