Description

Technical Field

[0001] The present invention relates to the technical field of die-casting forming, and particularly to a die-casting forming device for aluminum alloy components. Background Art

[0002] The die-casting forming technology for aluminum alloy components, as a key manufacturing process, has been widely applied in many high-tech fields such as automotive engineering and aerospace. The core of the die-casting forming technology for aluminum alloy components lies in using a high-pressure device to quickly inject the molten aluminum alloy into a precisely designed mold cavity. Once the metal fills the cavity, it will undergo a rapid cooling process, enabling the aluminum alloy to solidify and form parts with high-precision dimensions and complex structures within an extremely short time.

[0003] In the practical application of the die-casting forming technology for aluminum alloy components, there are problems of uneven mold temperature and solidification defects of the molten aluminum alloy. The traditional cooling system is difficult to ensure the stability of the mold temperature during continuous operation, resulting in the molten aluminum alloy injected at the initial stage may solidify prematurely due to local low temperature, forming defects such as incomplete filling or cold shut. The filling effect in the dead corner area of the mold is not good. The existing slag pocket design cannot effectively solve the problems of gas holes and shrinkage porosity. Moreover, the molten aluminum alloy needs to be transferred to the injection tube by external scooping. During this process, the molten aluminum alloy is exposed to the air, leading to an increase in oxidation inclusions and even the risk of instantaneous oxidation and fire. The oxidized slag mixed into the casting will significantly reduce the mechanical properties and increase the post-treatment cost. Summary of the Invention

[0009] As an improvement of the above solution, the control assembly further includes a first elastic member. A first elastic member is connected between the connecting rod and the clamping block.

[0029] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0030] An aluminum alloy component die-casting forming device, as Figures 1-12As shown in the figure, it includes a base 1, a protective shell 101, a machine base 2, a fixing frame 3, a hydraulic cylinder 4, a first mold 5, a first fixing plate 51, a second mold 6, a second fixing plate 61, an infusion tube 7, a drain tube 8, a connecting tube 10, a heating tube 11 and an aluminum injection assembly.

On the top of the machine base 2, the hydraulic cylinder 4 is fixedly connected. On the piston rod of the hydraulic cylinder 4, the first mold 5 is fixedly connected. The first mold 5 is slidably connected with the fixing frame 3. On the side of the fixing frame 3 away from the machine base, the second mold 6 is fixedly connected. On the sides of the first mold 5 and the second mold 6 close to each other, mold grooves 9 are opened. The mold groove 9 of the first mold 5 is deeper than the mold groove 9 of the second mold 6. On the tops of the first mold 5 and the second mold 6, the infusion tubes 7 are fixedly connected. On the bottoms of the first mold 5 and the second mold 6, the drain tubes 8 are fixedly connected.

The connecting tube 10 communicates with the mold groove 9 of the first mold 5. The connecting tube 10 is connected to an external air extraction system. On the side of the first mold 5 close to the second mold 6, the first fixing plate 51 is fixedly connected. On the side of the second mold 6 away from the first mold 5, the second fixing plate 61 is fixedly connected. On the sides of the first fixing plate 51 and the second fixing plate 61 close to each other, cooling grooves 511 are opened. On the side of the second mold 6 away from the first mold 5, a round groove 62 is opened. In the round groove 62, the heating tube 11 is fixedly connected. The heating tube 11 is fixedly connected to the second fixing plate 61. On the side of the base 1 away from the machine base 2, the aluminum injection assembly is connected. The aluminum injection assembly is located inside the protective shell 101 and is connected to the second mold 6.

[0031] As Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown in the figure, the aluminum injection assembly includes an aluminum alloy melting furnace 12, a metering tank 121, a high-pressure device 13, a injection rod 131, an aluminum injection pipe 14, and a control assembly. On the right side of the top of the base 1, there is a fixed connection with an aluminum alloy melting furnace 12 with heat preservation function. The aluminum alloy melting furnace 12 penetrates through the protective shell 101. At the bottom of the aluminum alloy melting furnace 12, there are fixed connections with a high-pressure device 13 and an aluminum injection pipe 14. At the bottom of the aluminum alloy melting furnace 12, there is a fixed connection with a metering tank 121. The metering tank 121 is communicated with the aluminum alloy melting furnace 12. The high-pressure device 13 is slidably connected with an injection rod 131. The injection rod 131 is slidably connected with the aluminum injection pipe 14. The injection rod 131 is located inside the aluminum injection pipe 14. The aluminum injection pipe 14 is communicated with the second mold 6. There is a through hole 141 on the aluminum injection pipe 14. The aluminum injection pipe 14 is fixedly connected with the metering tank 121. The aluminum injection pipe 14 is communicated with the metering tank 121 through the through hole 141. The volume of the metering tank 121 is the same as that of the aluminum injection pipe 14. The capacity of the metering tank 121 is the sum of the capacities of the mold cavities 9 of the first mold 5 and the second mold 6. A control assembly is connected to the metering tank 121.

[0032] As Figure 6 and Figure 7 shown in the figure, the control assembly includes a screw rod 15, a butterfly plate 16, a connecting rod 17, a guiding rod 18, a clamping block 19, and a first elastic member 20. The screw rod 15 is rotatably connected to the top of the metering tank 121. The screw rod 15 penetrates through the metering tank 121. A butterfly plate 16 adapted to the connection between the aluminum alloy melting furnace 12 and the metering tank 121 is fixedly connected to the screw rod 15. The butterfly plate 16 is located at the connection between the aluminum alloy melting furnace 12 and the metering tank 121. A guiding rod 18 is fixedly connected to the outer wall of the metering tank 121. The connecting rod 17 is slidably connected to the guiding rod 18. The connecting rod 17 is threadedly connected to the screw rod 15. The bottom of the connecting rod 17 is slidably connected to a clamping block 19. There is a clamping groove 1311 adapted to the clamping block 19 on the injection rod 131. The clamping groove 1311 and the through hole 141 are arranged in a staggered manner. The clamping groove 1311 is wedge-shaped. The side of the clamping groove 1311 away from the second mold 6 is set as an inclined surface. The inner diameter of the bottom of the clamping groove 1311 is larger than that of the top. A first elastic member 20 is fixedly connected between the connecting rod 17 and the clamping block 19. The first elastic member 20 is set as a helical spring.

[0033] As Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown in the figure, it further includes a connecting frame 21, a push rod 22, a limit block 23, a second elastic member 24, an L-shaped plate 25, a first cylinder 26, a second cylinder 27, an adjusting frame 28 and a pneumatic gripper 29. At least four push rods 22 are slidably connected to the first fixing plate 51 at intervals along the circumferential direction. The push rods 22 penetrate through the first mold 5 and the first fixing plate 51. A connecting frame 21 is fixedly connected between the ends of the push rods 22 far away from the first fixing plate 51. Limit blocks 23 are fixedly connected to the ends of the push rods 22 far away from the hydraulic cylinder 4. The limit blocks 23 can prevent the push rods 22 from detaching from the first fixing plate 51. Second elastic members 24 are fixedly connected between the push rods 22 and the first fixing plate 51. The second elastic members 24 are arranged as helical springs. An L-shaped plate 25 is rotatably connected to the side of the first fixing plate 51 far away from the first mold 5. A first cylinder 26 is fixedly connected to the L-shaped plate 25. A second cylinder 27 is fixedly connected to the piston rod of the first cylinder 26. An adjusting frame 28 is fixedly connected to the piston rod of the second cylinder 27. Two pneumatic grippers 29 are detachably connected to the adjusting frame 28, and the pneumatic grippers 29 can be removed to change their positions on the adjusting frame 28, so as to adapt to the demolding operation of aluminum alloy members with different shapes.

[0034] At first, the butterfly plate 16 is perpendicular to the base 1. The connection between the aluminum alloy melting furnace 12 and the metering tank 121 is in a passage state. The injection rod 131 blocks the through hole 141. The first elastic member 20 is in a compressed state. The clamping block 19 presses against the outer surface of the injection rod 131. The side of the limiting block 23 close to the second mold 6 is aligned with the mold groove 9 of the first mold 5. The second elastic member 24 is in a natural state. The L-shaped plate 25 rotates away from the second mold 6. When it is necessary to die-cast an aluminum alloy component, the first mold 5 is driven by the hydraulic cylinder 4 to move closer to the second mold 6, so that the first mold 5 fits tightly against the second mold 6. The aluminum alloy molten liquid is poured into the aluminum alloy melting furnace 12. The aluminum alloy melting furnace 12 with heat preservation function can ensure that the aluminum alloy molten liquid maintains an ideal temperature before being injected into the mold, thereby maintaining its best fluidity, reducing the temperature fluctuation of the aluminum alloy molten liquid during transfer and waiting, and reducing the risk of forming an oxide layer on the surface of the aluminum alloy molten liquid. The aluminum alloy molten liquid in the aluminum alloy melting furnace 12 flows into the metering tank 121 at a constant flow rate. After a period of time, when the aluminum alloy molten liquid is at the bottom of the aluminum alloy melting furnace 12, it means that the metering tank 121 is full of aluminum alloy molten liquid. The injection rod 131 is driven by the high-pressure device 13 to slide away from the second mold 6 along the aluminum injection pipe 14. The card slot 1311 gradually approaches the clamping block 19. When the card slot 1311 is aligned with the clamping block 19, the first elastic member 20 returns to its original state, causing the clamping block 19 to slide downward and engage into the card slot 1311. Continuing to drive the injection rod 131 to slide away from the second mold 6 through the high-pressure device 13, under the clamping action of the clamping block 19 and the card slot 1311, the injection rod 131 drives the clamping block 19 to move away from the metering tank 121, causing the connecting rod 17 to slide away from the metering tank 121 along the guide rod 18. The connecting rod 17 drives the screw rod 15 to rotate, causing the butterfly plate 16 to rotate 90 degrees. Thus, the butterfly plate 16 blocks the connection between the aluminum alloy melting furnace 12 and the metering tank 121. The injection rod 131 no longer blocks the through hole 141. The aluminum alloy molten liquid in the metering tank 121 flows into the aluminum injection pipe 14 at a constant flow rate through the through hole 141. Before the aluminum alloy molten liquid is injected into the mold groove 9, the second fixing plate 61 is heated by the heating pipe 11. The second fixing plate 61 conducts heat to the mold grooves 9 of the second mold 6 and the first mold 5. After a period of time, the injection rod 131 is driven by the high-pressure device 13 to slide closer to the second mold 6 along the aluminum injection pipe 14. The clamping block 19 slides along the inclined surface of the card slot 1311 and disengages from the card slot 1311. The first elastic member 20 is compressed. The injection rod 131 blocks the through hole 141 again. The injection rod 131 presses the aluminum alloy molten liquid in the aluminum injection pipe 14, so that the aluminum alloy molten liquid in the aluminum injection pipe 14 is injected into the mold grooves 9 of the first mold 5 and the second mold 6. The heated mold groove 9 can reduce the temperature difference when the aluminum alloy molten liquid contacts the first mold 5 and the second mold 6, avoiding premature solidification of the aluminum alloy molten liquid due to local supercooling, thereby improving the fluidity of the aluminum alloy molten liquid, making the filling process of the mold groove 9 smoother, and reducing the risk of forming cold laps or insufficient filling.When the injection rod 131 is at the maximum stroke position within the aluminum injection tube 14, a certain amount of air in the mold cavity 9 is extracted through the connecting pipe 10 using an air extraction system. Thereby, the air pressure in the mold cavity 9 can be effectively reduced, so that more gas and air can be discharged during the filling process of the molten aluminum alloy liquid. The low-pressure environment created by air extraction helps to promote the smoother inflow of the molten aluminum alloy liquid into the mold cavity 9, can reduce the formation of pores inside the aluminum alloy component, improve the density and mechanical properties of the aluminum alloy component. Then, the cooling system is used to circulate and inject and discharge the coolant through the liquid infusion pipe 7 and the liquid discharge pipe 8. Thereby, the molten aluminum alloy liquid in the mold cavity 9 can be rapidly cooled. Then, the hydraulic cylinder 4 drives the first mold 5 to move away from the second mold 6. The cooled aluminum alloy component is located in the mold cavity 9 of the first mold 5. Rotate the L-shaped plate 25 to make the pneumatic gripper 29 approach the mold cavity 9 of the first mold 5. The piston rod of the first cylinder 26 drives the second cylinder 27 to move to align the pneumatic gripper 29 with the mold cavity 9 of the first mold 5. Then, the piston rod of the second cylinder 27 drives the adjusting frame 28 to move closer to the mold cavity 9 of the first mold 5. The edge of the aluminum alloy component is clamped by the pneumatic gripper 29. When the first mold 5 drives the connecting frame 21 to move closer to the machine base 2, the machine base 2 presses the connecting seat, causing the push rod 22 to slide closer to the second mold 6, so that the push rod 22 pushes the aluminum alloy component, making the aluminum alloy component loose in the mold cavity 9 of the first mold 5. Thereby, the adhesion force between the aluminum alloy component and the mold cavity 9 can be overcome, and the demolding speed can be accelerated. Then, the piston rod of the second cylinder 27 drives the adjusting frame 28 to move away from the mold cavity 9 of the first mold 5, so that the pneumatic gripper 29 drives the aluminum alloy component to move out of the mold cavity 9 of the first mold 5. Thus, the demolding operation is completed. The pneumatic gripper 29 can provide precise gripping force and position control, ensuring that the aluminum alloy component can be accurately clamped every time, and can also effectively avoid the safety risks faced by manual demolding, improving safety. Then, the piston rod of the first cylinder 26 drives the second cylinder 27 to move away from the mold cavity 9 of the first mold 5, rotate the L-shaped plate 25 to reverse and reset it, and then take out the aluminum alloy component on the pneumatic gripper 29. Then, the hydraulic cylinder 4 drives the first mold 5 to move away from the machine base 2, so that the connecting frame 21 no longer contacts the machine base 2, and the second elastic member 24 returns to its original state to reset the push rod 22. Thus, a die-casting forming operation of an aluminum alloy component is completed.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
