Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum alloy ingot pressure casting, in particular to a high-rigidity aluminum alloy ingot pressure casting device and a use method. BACKGROUND

[0002] The aluminum alloy ingot is an alloy material prepared from pure aluminum and recycled aluminum as main raw materials and other materials as auxiliary materials. The aluminum alloy ingot is a basic raw material in the manufacturing industry and is applied to multiple fields such as the automobile industry, household appliances, building materials and aviation. The aluminum alloy ingot is usually formed by pressure casting with a pressure casting device.

[0003] The existing pressure casting device realizes the pressure casting forming of the aluminum alloy ingot in multiple ways. For example, the aluminum alloy structural part pressure casting mold disclosed in CN116748486A comprises an upper mold, an upper cavity is arranged on the lower end surface of the upper mold, the upper end of the upper mold is connected with a top plate through a main hydraulic cylinder, the top plate is fixedly connected with a U-shaped frame, the opening of the U-shaped frame is arranged horizontally, an injection pipe is arranged, one end of the injection pipe is in communication with the upper cavity, the other end of the injection pipe extends to the upper side through the upper mold, the top plate and the U-shaped frame, a lower mold is arranged, a lower cavity is arranged on the upper end surface of the lower mold, the lower mold is fixedly connected with the inner side wall of the U-shaped frame, and a controller is arranged and used for controlling the automatic operation of the pressure casting mold.

[0004] When the existing pressure casting device is used for pressure casting processing of the aluminum alloy ingot, the injection pipe is usually used to inject the aluminum alloy melt into the forming mold to realize internal pouring. In this way, the residual aluminum alloy melt in the injection pipe is coagulated with the aluminum alloy melt in the forming mold, that is, part of the internal pouring part is left on the formed aluminum alloy ingot, which needs to be removed later.

[0005] For example, the existing technology mentioned above realizes injection by directly injecting the aluminum alloy melt into the upper cavity through the injection pipe. In this way, the residual aluminum alloy melt in the injection pipe cannot be separated from the solution in the upper cavity, and the two are coagulated together. Therefore, not only the injection pipe is blocked, but also the residual internal pouring part in the injection pipe blocks the demolding of the formed aluminum alloy ingot, which has certain limitations.

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0056] Embodiment one: refer to Figures 1-4 A high-rigidity aluminum alloy ingot die casting device, comprising a die casting lower mold box 8 for aluminum alloy ingot die casting forming arranged on a die casting bottom tank 1, the die casting lower mold box 8 is used to realize the die casting forming of the aluminum alloy ingot.

[0057] The die casting device further comprises:

[0058] The support assembly is provided on the die-casting bottom box 1, in which a die-casting hydraulic cylinder 6 for driving the mold closing is provided, and a die-casting upper mold 13 is installed on the die-casting hydraulic cylinder 6 through a lifting assembly;

[0059] A support box 4 is fixedly mounted on the die-casting bottom box 1 , a die-casting top plate 5 is fixedly mounted on the support box 4 , and a die-casting hydraulic cylinder 6 is arranged on the die-casting top plate 5 .

[0060] The lifting assembly includes a plurality of limit guide rods 9 fixedly mounted between the die-casting top plate 5 and the die-casting lower die box 8, and a die-casting lifting plate 7 is slidably mounted between the plurality of limit guide rods 9, and the die-casting lifting plate 7 is fixedly mounted on the lower end of the die-casting hydraulic cylinder 6, and the die-casting upper mold 13 is fixedly mounted on the lower part of the die-casting lifting plate 7;

[0061] A plurality of limiting guide rods 9 are used to limit the die-casting lifting plate 7 so that it can only move vertically up and down without position displacement. When the die-casting hydraulic cylinder 6 is started, it will drive the die-casting lifting plate 7 to move up and down, and can drive the die-casting upper mold 13 at the bottom of the die-casting lifting plate 7 to move up and down.

[0062] The lower forming die 10 is disposed in the die-casting lower die box 8, and the lower forming die 10 cooperates with the die-casting upper die 13 for die-casting of the aluminum alloy ingot;

[0063] When the die-casting hydraulic cylinder 6 is started, the cooperation of the lifting assembly can drive the die-casting upper mold 13 to move up and down, so that the die-casting upper mold 13 moves down and is engaged with the forming lower mold 10, thereby realizing the die-casting upper mold 13 and the forming lower mold 10. At this time, the space between the forming lower mold 10 and the die-casting upper mold 13 is the forming cavity of the aluminum alloy ingot, thereby completing the die-casting of the aluminum alloy ingot;

[0064] The downward movement distance and downward pressure of the die-casting upper die 13 can be flexibly controlled by the die-casting hydraulic cylinder 6, thereby stably pressurizing the aluminum alloy melt in the forming lower die 10 to achieve die-casting of the aluminum alloy ingot.

[0065] In a further embodiment, the liquid injection unit is provided with a liquid injection pipe 12 for pouring the aluminum alloy melt. The liquid injection pipe 12 is connected to an external melting furnace and is used to conduct the aluminum alloy melt melted in the melting furnace to the lower forming mold 10, thereby completing the die-casting of the aluminum alloy ingot.

[0066] The injection unit is used to realize the conduction and cut-off diversion of the aluminum alloy melt, so that the aluminum alloy melt in the injection main pipe 12 can be separated from the aluminum alloy melt in the forming lower mold 10 after the injection is completed, thereby avoiding the aluminum alloy melt in the forming lower mold 10 and the aluminum alloy in-cast residual melt in the injection main pipe 12 from being integrally formed, and realizing automatic cut-off and separation of the aluminum alloy ingot and the in-cast parts, thereby eliminating the need to separate the redundant in-cast parts on the aluminum alloy ingot.

[0067] The cooling unit is arranged in the die-casting lower mold box 8. The cooling unit is used to quickly cool down and cool the aluminum alloy melt that has been die-cast in the molding lower mold 10. At the same time, the high temperature of the aluminum alloy melt is used to realize the automatic ejection and demolding of the aluminum alloy ingot and the discharge of the cast parts, thereby improving the die-casting molding efficiency of the aluminum alloy ingot.

[0068] A main control box 2 is provided on the side of the die-casting bottom box 1, and a control panel 3 cooperating with the main control box 2 is provided on the front of the die-casting bottom box 1. The control panel 3 cooperates with the main control box 2 to control the opening and closing and operating status of the die-casting hydraulic cylinder 6, the injection unit and the cooling unit, so as to realize the automatic die-casting and demolding of the aluminum alloy ingot.

[0069] Example 2: Reference Figures 2-8 The technical difference between this embodiment and the first embodiment is that a cut-off component is provided between the lower forming mold 10 and the liquid injection main pipe 12, and the cut-off component is used to intercept the aluminum alloy melt and promote the forming of the inner casting.

[0070] The cut-off assembly includes an inner pouring hole 36 provided on the lower forming die 10 for conducting the aluminum alloy melt, and an inner pouring pipe 26 is fixedly installed between the inner pouring hole 36 and the liquid injection main pipe 12. A pusher ring 29 is slidably installed in the inner pouring pipe 26, and the pusher ring 29 cooperates with the end of the liquid injection main pipe 12;

[0071] After the die-casting upper mold 13 and the forming lower mold 10 are closed, the injection main pipe 12 can be opened to inject the aluminum alloy melt into the inner pouring pipe 26, and then injected into the forming lower mold 10 through the inner pouring hole 36 on the forming lower mold 10, thereby completing the automatic pouring and filling of the aluminum alloy melt.

[0072] When the aluminum alloy melt enters the inner pouring pipe 26 through the liquid injection main pipe 12, it will enter the right end of the inner push ring 29 (see the appendix of the specification). Figure 14 As shown in the direction, the aluminum alloy melt will only be filled between the right side of the push ring 29 in the inner casting tube 26 and the inner casting hole 36. When the cut-off between the inner casting hole 36 and the lower forming mold 10 is completed, the aluminum alloy melt remaining on the right side of the push ring 29 and in the inner casting hole 36 will be the residual inner casting liquid, which will form an inner casting after cooling, and the inner casting will remain in the inner casting tube 26.

[0073] A blocking mechanism is installed between the ingrowing hole 36 and the die-casting lifting plate 7. The blocking mechanism includes a blocking hydraulic rod 11 fixedly mounted on the die-casting lifting plate 7. A blocking communication groove 22 communicating with the ingrowing hole 36 is provided on the lower forming die 10. A connecting frame 15 is fixedly mounted on the driving end of the blocking hydraulic rod 11. A blocking closure plate 14 cooperating with the blocking communication groove 22 and the ingrowing hole 36 is fixedly mounted on the connecting frame 15.

[0074] After the aluminum alloy melt is injected, before the aluminum alloy melt cools and solidifies, the blocking hydraulic rod 11 is activated to drive the connecting frame 15 and the blocking cutoff plate 14 to move downward, so that the blocking cutoff plate 14 moves downward to the front of the inner casting hole 36. At this time, the blocking cutoff plate 14 will block the aluminum alloy melt, so that the aluminum alloy melt in the inner casting hole 36 is separated from the aluminum alloy melt in the forming lower mold 10, thereby completing automatic blocking, thereby preventing the aluminum alloy ingot and the inner casting from being formed integrally;

[0075] The blocking plate 14 is provided with a connecting hole that matches the inner casting hole 36 (see the attached manual). Figure 5 As shown in FIG2 , when the die-casting upper mold 13 and the forming lower mold 10 are closed, the blocking cutoff plate 14 is driven by the blocking hydraulic rod 11 to move downward into the blocking communicating groove 22, and the communicating hole and the inner pouring hole 36 are at the same horizontal position, so that the blocking cutoff plate 14 does not block the flow and infusion of the aluminum alloy melt, and the aluminum alloy melt in the inner pouring hole 36 does not flow out through the blocking communicating groove 22;

[0076] When blocking is required, the blocking cutoff plate 14 will continue to move downward so that the upper communicating hole is not at the same level as the inner casting hole 36 . At this time, the blocking cutoff plate 14 will automatically block and intercept the inner casting hole 36 .

[0077] Example 3: Reference Figures 1-3 as well as Figures 8-16 The technical difference between this embodiment and the second embodiment is that the cooling unit includes a cooling component and a discharging component. The cooling component is provided with a condensation circulation pipe 21 for promoting the cooling and shaping of the aluminum alloy ingot. The discharging component is used to realize the demolding of the formed aluminum alloy ingot.

[0078] The cooling assembly includes a liquid storage tank 18 fixedly mounted in the die casting lower mold box 8, and the liquid storage tank 18 is filled with condensate for cooling the heat-absorbing condensate. A cooling circulation pump 33 for conveying the condensate is fixedly mounted in the liquid storage tank 18. A condensation circulation pipe 21 is fixedly mounted on the outside of the lower molding die 10, and an upper liquid pipe 34 is fixedly connected between the liquid inlet end of the condensation circulation pipe 21 and the liquid outlet end of the cooling circulation pump 33. A liquid return pipe 32 is connected between the liquid outlet end of the condensation circulation pipe 21 and the liquid storage tank 18.

[0079] When the aluminum alloy melt in the lower mold 10 is filled and the inner runner 36 is blocked, the cooling circulating pump 33 in the liquid storage tank 18 can be started. When the cooling circulating pump 33 is started, the condensate in the liquid storage tank 18 is transported to the condensation circulating pipe 21 through the liquid inlet pipe 34, and then flows in the condensation circulating pipe 21 and returns to the liquid storage tank 18 through the liquid return pipe 32, thereby completing the automatic circulation of the condensate. The condensation circulating pipe 21 is arranged outside the lower mold 10, so that the heat of the aluminum alloy melt in the lower mold 10 can be absorbed and taken away during the circulation, thereby realizing rapid cooling of the aluminum alloy ingot in the lower mold 10.

[0080] In a further embodiment, the discharge assembly includes a stepped opening 17 formed in the bottom of the lower mold 10, and a lifting platform 16 is fitted in the stepped opening 17. A heat-insulating storage ring 27 is fixedly installed in the liquid storage tank 18, and the heat-insulating storage ring 27 is filled with heat-conducting water. A telescopic heat-conducting rod 24 is fixedly installed between the lower part of the lifting platform 16 and the liquid storage tank 18, and the telescopic heat-conducting rod 24 is located in the heat-insulating storage ring 27.

[0081] The heat of the aluminum alloy melt in the lower mold 10 is conducted to the lifting platform 16, and the heat on the lifting platform 16 is conducted to the heat-insulating storage ring 27 through the telescopic heat-conducting rod 24. At this time, the heat-conducting water in the heat-insulating storage ring 27 absorbs heat and vaporizes into water vapor under the action of high heat, and at this time, the water vapor accumulates in the heat-insulating storage ring 27.

[0082] Two steam cylinders 25 are fixedly connected in the liquid storage tank 18, and both of the two steam cylinders 25 are located inside the heat-insulating storage ring 27. A piston pushing piece one 28 is vertically and slidingly installed in each of the two steam cylinders 25, and the upper end of each of the two piston pushing piece ones 28 is fixedly installed on the lower part of the lifting platform 16.

[0083] When the aluminum alloy ingot in the lower mold 10 is cooled, the two steam cylinders 25 can be opened. When the two steam cylinders 25 are opened, the water vapor in the heat-insulating storage ring 27 quickly rushes into the steam cylinders 25 and pushes the piston pushing piece one 28 in the steam cylinders 25 upward. When the piston pushing piece one 28 moves upward, it pushes the lifting platform 16 upward, thereby pushing the formed aluminum alloy ingot on the lifting platform 16 upward, so that the aluminum alloy ingot moves upward and separates from the lower mold 10, thereby completing the automatic upward moving and demolding process of the aluminum alloy ingot.

[0084] In further embodiments, the liquid injection main pipe 12 is provided with a pushing assembly for realizing the discharge of the inner cast, the pushing assembly comprising a reset spring rod 31 fixedly installed between the pushing ring 29 and the inner pouring pipe 26, the inner pouring pipe 26 is fixedly installed with a conducting square pipe 30, and the conducting square pipe 30 is fixedly communicated with the heat insulation storage ring 27 through a gas conducting elbow 23 for conducting steam, the conducting square pipe 30 is horizontally slidably installed with a piston pushing piece two 35, and the piston pushing piece two 35 is fixedly installed on the pushing ring 29;

[0085] When the aluminum alloy ingot is demolded, the gas conducting elbow 23 is opened at this time, and the water vapor in the heat insulation storage ring 27 will flow into the conducting square pipe 30 through the gas conducting elbow 23 at this time, and the increase of water vapor in the conducting square pipe 30 will push the piston pushing piece two 35 to move, thereby pushing the pushing ring 29 to move horizontally in the inner pouring pipe 26, and the pushing ring 29 will push the inner cast in the inner pouring pipe 26 to move out, so that it falls into the forming lower mold 10 through the inner pouring hole 36, thereby realizing the automatic discharge of the inner cast, so that the inner cast will not be accumulated in the inner pouring pipe 26 to cause blockage.

[0086] When the water vapor in the conducting square pipe 30 is cooled, it will be liquefied into heat conducting water, and the pushing ring 29 will stretch the reset spring rod 31 when it moves, and when the water vapor is liquefied, the reset spring rod 31 will automatically contract and reset to drive the pushing ring 29 and the piston pushing piece two 35 to return to the original position, and when the piston pushing piece two 35 resets, it will squeeze the liquefied heat conducting water in it, so that the liquefied heat conducting water returns to the heat insulation storage ring 27 through the gas conducting elbow 23, and the automatic recovery and replenishment of the heat conducting water is completed.

[0087] The water vapor in the upper cylinder 25 will directly fall into the heat insulation storage ring 27 after being cooled and liquefied, at this time the piston pushing piece one 28 will automatically move down and reset to drive the lifting platform 16 to move down and be clamped into the stepped opening 17, thereby realizing the automatic clamping and plugging of the stepped opening 17, and at this time the die casting preparation work of the aluminum alloy ingot can be carried out again.

[0088] The die casting lower mold box 8 is provided with a collecting assembly, the collecting assembly comprising a storage box 19 fixedly installed in the die casting lower mold box 8 for storing the inner cast, and the storage box 19 is provided with a storage opening, and the liquid storage tank 18 is fixedly installed with two inclined guide plates 20 for conducting the inner cast;

[0089] When the formed aluminum alloy ingot is demolded, the lifting platform 16 moves up and separates from the stepped opening 17 at this time, that is, the stepped opening 17 is in a communicating state at this time, and when the inner cast is pushed out and falls into the forming lower mold 10, it will directly fall onto the inclined guide plate 20 through the stepped opening 17, and will fall into the storage box 19 through the storage opening after rolling on the inclined guide plate 20, thereby realizing the automatic collection of the inner cast, and effectively avoiding the influence of the inner cast on the subsequent automatic die casting process of the aluminum alloy ingot.

[0090] The specific working principle of the present die casting device is:

[0091] When the die casting of the aluminum alloy ingot is performed, the matching of the die casting hydraulic cylinder 6 lifting assembly is started to drive the die casting upper mold 13 to move downward, so that the die casting upper mold 13 moves downward and is clamped into the forming lower mold 10, and the mold closing of the die casting upper mold 13 and the forming lower mold 10 is completed.

[0092] When the die casting upper mold 13 and the forming lower mold 10 are completely closed, the liquid injection main pipe 12 can be opened to inject the aluminum alloy melt into the inner runner 26, and then through the inner pouring hole 36 on the forming lower mold 10, the aluminum alloy melt is injected into the forming lower mold 10, and the automatic filling of the aluminum alloy melt is completed.

[0093] When the injection of the aluminum alloy melt is completed, before the aluminum alloy melt cools and solidifies, the plugging hydraulic rod 11 is started to drive the connecting frame 15 and the plugging baffle 14 to move downward, so that the plugging baffle 14 moves to the front of the inner pouring hole 36, at this time the plugging baffle 14 will intercept the aluminum alloy melt, so that the aluminum alloy melt in the inner pouring hole 36 is separated from the aluminum alloy melt in the forming lower mold 10, and then the automatic blocking is completed, thereby avoiding the integrated molding of the aluminum alloy ingot and the inner runner.

[0094] When the aluminum alloy melt in the forming lower mold 10 is filled and the inner pouring hole 36 is blocked, the cooling circulating pump 33 in the liquid storage tank 18 is started to deliver the condensate in the liquid storage tank 18 to the condensation circulating pipe 21 through the liquid inlet pipe 34, and then after circulating in the condensation circulating pipe 21, it returns to the liquid storage tank 18 through the liquid return pipe 32, and the automatic circulation of the condensate is completed. In the process of circulating flow, the heat of the aluminum alloy melt in the forming lower mold 10 is absorbed and taken away, thereby realizing the rapid cooling of the aluminum alloy ingot in the forming lower mold 10.

[0095] The heat of the aluminum alloy melt in the forming lower mold 10 is conducted to the lifting platform 16, and the heat on the lifting platform 16 is conducted to the heat storage ring 27 through the telescopic heat conducting rod 24. At this time, the heat conducting water in the heat storage ring 27 will absorb heat and vaporize into water vapor under the action of high heat, and at this time the water vapor will accumulate in the heat storage ring 27.

[0096] When the aluminum alloy ingot in the forming lower mold 10 is cooled, the two steam cylinders 25 are opened, the water vapor in the heat storage ring 27 is quickly injected into the steam cylinder 25, and the piston pushing part 28 and the lifting platform 16 are pushed upward, thereby pushing the aluminum alloy ingot on the lifting platform 16 upward and separating from the forming lower mold 10, and the automatic upward demolding process of the aluminum alloy ingot is completed.

[0097] When the aluminum alloy ingot is demolded, the air guide elbow 23 is opened to make the water vapor in the heat insulation storage ring 27 flow into the conduction square tube 30 through the air guide elbow 23, and the water vapor in the conduction square tube 30 will push the piston pushing piece two 35 to move, and then push the pushing ring 29 to move horizontally in the inner pouring pipe 26, so that the inner pouring piece in the inner pouring pipe 26 is pushed out and falls into the lower mold 10 through the inner pouring hole 36, so that the inner pouring piece is automatically pushed out and does not accumulate in the inner pouring pipe 26 to cause blockage.

[0098] When the aluminum alloy ingot is demolded, the air guide elbow 23 is opened to make the water vapor in the heat insulation storage ring 27 flow into the conduction square tube 30 through the air guide elbow 23, and the water vapor in the conduction square tube 30 will push the piston pushing piece two 35 to move, and then push the pushing ring 29 to move horizontally in the inner pouring pipe 26, so that the inner pouring piece in the inner pouring pipe 26 is pushed out and falls into the lower mold 10 through the inner pouring hole 36, so that the inner pouring piece is automatically pushed out and does not accumulate in the inner pouring pipe 26 to cause blockage.

[0099] The embodiment of the application also provides a use method of the high-rigidity aluminum alloy ingot die casting device, which is used for the high-rigidity aluminum alloy ingot die casting device and includes the following steps.

[0100] S1, when the aluminum alloy ingot is die cast, the die casting hydraulic cylinder 6 is started to drive the upper mold 13 to move downward and be clamped into the lower mold 10, and the mold is closed.

[0101] S2, the liquid injection main pipe 12 is started to guide the aluminum alloy melt into the lower mold 10, and the injection pressure and speed are synchronously controlled.

[0102] S3, after the liquid injection is completed, the aluminum alloy melt is blocked by the cutting assembly, so that the liquid injection main pipe 12 is separated from the aluminum alloy melt in the lower mold 10, and the inner pouring piece of the aluminum alloy is formed.

[0103] S4, the cooling assembly in the cooling unit is used to promote the cooling and forming of the aluminum alloy ingot in the lower mold 10.

[0104] S5, the aluminum alloy ingot formed in the lower mold 10 is pushed out by the discharging assembly, and the inner pouring piece is removed and collected by cooperating with the pushing assembly.

[0105] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
