Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting processing, and particularly relates to a die-casting mold for aluminum alloy castings. Background Art

[0002] Aluminum alloy castings refer to equipment and devices made of pure aluminum or aluminum alloy obtained through casting processing. This process usually involves pouring molten aluminum or aluminum alloy into the cavity of a sand mold or metal mold to obtain aluminum parts or aluminum alloy parts of various shapes and sizes; a die-casting mold is a tool for casting metal parts and is used to complete the die-casting process on a dedicated die-casting forging machine.

[0003] However, when the existing die-casting mold for aluminum alloy castings is in use, usually after the die-casting mold is closed, materials are transported into the die-casting mold to make the aluminum alloy castings processed and formed. However, there will be residual gas in the die-casting mold. After the aluminum alloy casting material enters the die-casting mold, the gas will enter the aluminum alloy casting material, which will cause bubbles to be generated in the formed aluminum alloy castings, affecting the processing quality of the aluminum alloy castings to a certain extent. After the aluminum alloy castings are formed in the die-casting mold, the surface of the aluminum alloy castings still has a relatively high temperature, and the staff cannot directly take them, which affects the processing efficiency of the aluminum alloy castings to a certain extent. Therefore, a die-casting mold for aluminum alloy castings is provided. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a die-casting mold for aluminum alloy castings. By setting the fixed pipe A, fixed pipe B, piston block, outer frame, cooling cavity A, cooling cavity B, refrigerating sheet, vacuum pump, and heat conduction layer B, the utility model solves the problems that when the existing die-casting mold for aluminum alloy castings is in use, it is inconvenient to perform vacuum treatment on the die-casting mold, and the cooling of the aluminum alloy castings in the die-casting mold is slow, affecting the processing quality and processing efficiency of the aluminum alloy castings.

[0005] The technical solution adopted by the present utility model to solve its technical problems is a die-casting mold for aluminum alloy castings, including a frame, a die-casting mold A and a die-casting mold B. A cylinder A providing power is bolted inside the frame, and the power output end of the cylinder A is screwed with a drive frame that drives the movement of the die-casting mold B. A feeding port for allowing the aluminum alloy casting material to enter the interiors of the die-casting mold A and the die-casting mold B is arranged outside the die-casting mold B. A fixing frame is welded outside the frame, and a cylinder B providing power is bolted inside the fixing frame. The power output end of the cylinder B is screwed with a support plate. A driving rod is welded outside the support plate, and the end of the driving rod away from the support plate extends into the die-casting mold A. An outer frame is arranged outside the die-casting mold A. A heat conduction layer B for transferring the heat on the die-casting mold A is adhered inside the outer frame. A cooling cavity A and a cooling cavity B for cooling the die-cast aluminum alloy casting are arranged inside the outer frame, and the cooling cavity B is located inside the cooling cavity A. A refrigerating sheet is screwed inside the outer frame. A through hole is opened on the surface of the die-casting mold A. A fixing pipe B is arranged outside the die-casting mold A, and one end of the fixing pipe B away from the die-casting mold A is screwed with a corrugated pipe. A fixing pipe A is inserted outside the corrugated pipe, and one end of the fixing pipe A away from the corrugated pipe is screwed with a vacuum pump for pumping vacuum. A piston block for sealing the through hole on the die-casting mold A is adhered inside the corrugated pipe. An electric telescopic rod for driving the piston block inside the corrugated pipe to move is screwed on one side of the frame. An electric push rod is bolted inside the frame. A heat conduction layer A for transferring the heat outward is adhered outside the outer frame.

[0006] By adopting the above technical solution, when machining the aluminum alloy casting, the external controller causes the cylinder A inside the frame to drive the drive frame to move, and the drive frame drives the die-casting mold B to be connected with the die-casting mold A. Subsequently, the vacuum pump outside the frame is under the action of the controller, and the vacuum pump pumps gas inside the corrugated pipe through the fixing pipe A. Then, the fixing pipe B on one side of the corrugated pipe performs vacuum pumping treatment on the die-casting mold A and the die-casting mold B through the through hole opened on the die-casting mold A. After the vacuum pumping is completed, the electric telescopic rod inside the frame is under the action of the external controller, and the electric telescopic rod drives the piston block inside the corrugated pipe to move, the corrugated pipe is compressed, and the piston block inside the corrugated pipe moves into the through hole opened on the surface of the die-casting mold A, so as to seal the through hole for vacuum pumping on the die-casting mold A, thereby facilitating the discharge of the residual gas inside the die-casting mold A and the die-casting mold B, avoiding the generation of bubbles on the aluminum alloy casting, and improving the machining quality of the aluminum alloy casting.

[0007] After the die-casting mold B is connected to the die-casting mold A, the aluminum alloy casting material enters the interiors of the die-casting mold B and the die-casting mold A through the injection port on the surface of the die-casting mold B. Then, an external water pipe is connected to the outer frame, allowing external water to enter the cooling cavity B within the outer frame. Next, the heat within the die-casting mold A is transferred outward through the heat-conducting layer B, and the water in the cooling cavity absorbs the heat. At the same time, the refrigerating sheet within the outer frame is a semiconductor refrigerating sheet that delivers cold to the cooling cavity A, and the cooling cavity A delivers the cold to the cooling cavity B, keeping the water in the cooling cavity B at a low temperature. Moreover, the external structure of the die-casting mold B is the same as that of the die-casting mold A, thus facilitating the cooling treatment of the aluminum alloy castings within the die-casting mold A and the die-casting mold B and improving the processing efficiency of the aluminum alloy castings.

[0008] Specifically, a placement rack is screw-fixed to the end of the electric push rod away from the frame, and a foam board for protecting the processed aluminum alloy castings is screw-fixed inside the placement rack.

[0009] By adopting the above technical solution, after the aluminum alloy castings in the die-casting mold A and the die-casting mold B are formed, the external controller causes the electric push rod within the frame to drive the placement rack to move, so that the placement rack moves below the die-casting mold A and the die-casting mold B. Subsequently, the formed aluminum alloy castings enter the placement rack, and the foam board within the placement rack buffers the entering aluminum alloy castings, thus facilitating the collection and processing of the formed aluminum alloy castings.

[0010] Specifically, a fan for dissipating heat from the hot end of the refrigerating sheet is screw-fixed to the surface of the outer frame.

[0011] By adopting the above technical solution, when the refrigerating sheet within the outer frame is working, the fan blades on the surface of the outer frame rotate at high speed, dissipating the heat of the refrigerating sheet.

[0012] Specifically, the inner size of the through hole matches the outer size of the piston block.

[0013] By adopting the above technical solution, when the piston block enters the through hole opened on the die-casting mold A, the inner side of the through hole fits with the outside of the piston block, facilitating the entry of the piston block into the interior of the through hole.

[0014] Specifically, the input ends of the fan, the electric push rod, the electric telescopic rod, the cylinder A, the vacuum pump, the cylinder B, and the refrigerating sheet are all electrically connected to the power supply end of the external power supply.

[0015] By adopting the above technical solution, by connecting to the external power supply, the electrical equipment operates normally.

[0016] The beneficial effects of the present utility model:

[0017] (1) For the die-casting mold of an aluminum alloy casting described in the present utility model, when machining the aluminum alloy casting, the external controller causes the cylinder A in the frame to drive the driving frame to move. The driving frame drives the die-casting mold B to connect with the die-casting mold A. Subsequently, the vacuum pump outside the frame is under the action of the controller. The vacuum pump pumps out the gas inside the bellows of the fixed pipe A. Then, the fixed pipe B on one side of the bellows conducts vacuum pumping treatment on the die-casting mold A and the die-casting mold B through the through holes opened on the die-casting mold A. After the vacuum pumping is completed, the electric telescopic rod in the frame is under the action of the external controller. The electric telescopic rod drives the piston block inside the bellows to move, the bellows is compressed, and the piston block inside the bellows moves into the through holes opened on the surface of the die-casting mold A, so as to seal the through holes for vacuum pumping on the die-casting mold A, thereby facilitating the discharge of the residual gas inside the die-casting mold A and the die-casting mold B, avoiding the generation of bubbles on the aluminum alloy casting, and improving the processing quality of the aluminum alloy casting;

[0018] (2) For the die-casting mold of an aluminum alloy casting described in the present utility model, after the die-casting mold B is connected with the die-casting mold A, the aluminum alloy casting material enters the inside of the die-casting mold B and the die-casting mold A through the injection port on the surface of the die-casting mold B. Then, the external water pipe is connected to the outer frame, so that the external water enters the cooling chamber B inside the outer frame. Then, the heat inside the die-casting mold A is transferred outward through the heat conduction layer B, and the water in the cooling chamber absorbs the heat. At the same time, the refrigerating sheet in the outer frame is a semiconductor refrigerating sheet, which conveys the cold quantity to the cooling chamber A. The cooling chamber A conveys the cold quantity to the cooling chamber B, so that the water in the cooling chamber B remains in a low-temperature state, and the external structure of the die-casting mold B is the same as the external structure of the die-casting mold A, thereby facilitating the cooling treatment of the aluminum alloy casting inside the die-casting mold A and the die-casting mold B and improving the processing efficiency of the aluminum alloy casting.

[0019] (3) For the die-casting mold of an aluminum alloy casting described in the present utility model, after the aluminum alloy casting inside the die-casting mold A and the die-casting mold B is formed, the external controller causes the electric push rod in the frame to drive the placing frame to move, so that the placing frame moves below the die-casting mold A and the die-casting mold B. Subsequently, the external controller causes the cylinder A and the cylinder B to work. The cylinder A drives the die-casting mold B to separate from the die-casting mold A. Then, the cylinder B drives the support plate to move, the support plate pushes the driving rod to move, and the driving rod drives the formed aluminum alloy casting inside the die-casting mold A to move. Subsequently, the formed aluminum alloy casting enters the placing frame, and the foam board inside the placing frame buffers the entering aluminum alloy casting, thereby facilitating the collection and processing of the formed aluminum alloy casting.

A fixing frame 9 is welded to the outside of the frame 1, and a cylinder B 10 providing power is bolted to the inside of the fixing frame 9. A support plate 11 is fixed by screws to the power output end of the cylinder B 10. A driving rod 12 is welded to the outside of the support plate 11, and one end of the driving rod 12 away from the support plate 11 extends into the die-casting mold A 3. An outer frame 5 is provided outside the die-casting mold A 3. A heat conduction layer B 26 for transferring the heat on the die-casting mold A 3 is adhered to the inside of the outer frame 5. A cooling cavity A 23 and a cooling cavity B 24 for cooling the die-cast aluminum alloy casting are provided inside the outer frame 5, and the cooling cavity B 24 is located inside the cooling cavity A 23. A refrigerating sheet 21 is fixed by screws to the inside of the outer frame 5. A through hole 25 is opened on the surface of the die-casting mold A 3. A fixing pipe B 17 is provided outside the die-casting mold A 3, and a corrugated pipe 16 is fixed by screws to the end of the fixing pipe B 17 away from the die-casting mold A 3. A fixing pipe A 15 is inserted into the outside of the corrugated pipe 16, and a vacuum pump 13 for pumping vacuum is fixed by screws to the end of the fixing pipe A 15 away from the corrugated pipe 16. A piston block 27 for sealing the through hole 25 on the die-casting mold A 3 is adhered to the inside of the corrugated pipe 16. An electric telescopic rod 14 for driving the piston block 27 inside the corrugated pipe 16 to move is fixed by screws to one side of the frame 1. An electric push rod 20 is bolted to the inside of the frame 1. A heat conduction layer A 4 for transferring the heat outward is adhered to the outside of the outer frame 5.

[0027] During use, when processing the aluminum alloy casting, the external controller causes the cylinder A 2 inside the frame 1 to drive the movement of the driving frame 8, and the driving frame 8 drives the die-casting mold B 6 to be connected with the die-casting mold A 3. Subsequently, the vacuum pump 13 outside the frame 1 is affected by the controller, and the vacuum pump 13 pumps gas into the corrugated pipe 16 through the fixing pipe A 15. Subsequently, the fixing pipe B 17 on one side of the corrugated pipe 16 conducts vacuum pumping treatment on the die-casting mold A 3 and the die-casting mold B 6 through the through hole 25 opened on the die-casting mold A 3. After the vacuum pumping is completed, the electric telescopic rod 14 inside the frame 1 is affected by the external controller, and the electric telescopic rod 14 drives the piston block 27 inside the corrugated pipe 16 to move. The corrugated pipe 16 is compressed, and the piston block 27 inside the corrugated pipe 16 moves into the through hole 25 opened on the surface of the die-casting mold A 3, so as to seal the through hole 25 for vacuum pumping on the die-casting mold A 3, thereby facilitating the discharge of the residual gas inside the die-casting mold A 3 and the die-casting mold B 6, avoiding the generation of bubbles on the aluminum alloy casting, and improving the processing quality of the aluminum alloy casting.

[0028] When the die-casting mold B6 is connected to the die-casting mold A3, the aluminum alloy casting material enters the die-casting mold B6 and the die-casting mold A3 through the injection port 7 on the surface of the die-casting mold B6, and then the external water pipe is connected to the external frame 5, so that the external water enters the cooling cavity B24 in the external frame 5, and then the heat in the die-casting mold A3 is transferred outward through the heat conductive layer B26, and the water in the cooling cavity absorbs the heat. At the same time, the refrigeration plate 21 in the external frame 5 is a semiconductor refrigeration plate 21 that transports the cold energy to the cooling cavity A23, and the cooling cavity A23 transports the cold energy to the cooling cavity B24, so that the water in the cooling cavity B24 maintains a low temperature state, and the external structure of the die-casting mold B6 is the same as the external structure of the die-casting mold A3, so as to facilitate the cooling treatment of the aluminum alloy castings in the die-casting mold A3 and the die-casting mold B6, and improve the processing efficiency of the aluminum alloy castings.

[0029] In order to collect and process the formed aluminum alloy castings, for example, Figure 1 As shown, the utility model further includes that a placement frame 18 is screwed to one end of the electric push rod 20 away from the frame 1, and a foam plate 19 for protecting the processed aluminum alloy casting is screwed to the inner side of the placement frame 18.

[0030] During use, after the aluminum alloy castings are formed in the die-casting molds A3 and B6, the external controller enables the electric push rod 20 in the frame 1 to drive the placement rack 18 to move, so that the placement rack 18 moves to the bottom of the die-casting molds A3 and B6, and then the formed aluminum alloy castings enter the placement rack 18. The foam plate 19 in the placement rack 18 buffers the entering aluminum alloy castings, thereby facilitating the collection and processing of the formed aluminum alloy castings.

[0031] In order to dissipate the heat of the cooling plate 21, for example, Figure 3 As shown, the utility model also includes a fan 22 for dissipating heat from the hot end of the refrigeration plate 21 fixed with screws on the surface of the outer frame 5.

[0032] During use, when the cooling fins 21 in the outer frame 5 are working, the blades of the fan 22 on the surface of the outer frame 5 rotate at a high speed, so that the heat of the cooling fins 21 is dissipated.

[0033] In order to allow the piston block 27 to enter the through hole 25, for example, Figure 2 As shown, the utility model also includes that the inner size of the through hole 25 is consistent with the outer size of the piston block 27.

[0034] During use, when the piston block 27 enters the through hole 25 provided on the die-casting mold A3 , the inner side of the through hole 25 matches the outer side of the piston block 27 , so that the piston block 27 can enter the interior of the through hole 25 .

[0035] In order to use the electrical equipment to work normally, for example,Figure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , the utility model further includes that the input ends of the fan 22, the electric push rod 20, the electric telescopic rod 14, the cylinder A2, the vacuum pump 13, the cylinder B10 and the refrigeration sheet 21 are all electrically connected to the power supply end of an external power supply.

[0036] During use, by connecting to an external power supply, the electrical equipment works normally.

[0037] When the utility model is in use and when machining an aluminum alloy casting, an external controller causes the cylinder A2 in the frame 1 to drive the driving frame 8 to move, the driving frame 8 drives the die-casting mold B6 to be connected to the die-casting mold A3. Subsequently, the vacuum pump 13 outside the frame 1 is under the action of the controller, and the vacuum pump 13 pumps out the gas in the fixed pipe A15 and the corrugated pipe 16. Then, the fixed pipe B17 on one side of the corrugated pipe 16 conducts vacuum pumping treatment on the die-casting mold A3 and the die-casting mold B6 through the through hole 25 opened on the die-casting mold A3. After the vacuum pumping is completed, the electric telescopic rod 14 in the frame 1 is under the action of the external controller, and the electric telescopic rod 14 drives the piston block 27 in the corrugated pipe 16 to move. The corrugated pipe 16 is compressed, and the piston block 27 in the corrugated pipe 16 moves into the through hole 25 opened on the surface of the die-casting mold A3, so as to seal the through hole 25 for vacuum pumping on the die-casting mold A3, thereby facilitating the discharge of the residual gas in the die-casting mold A3 and the die-casting mold B6, avoiding the generation of air bubbles on the aluminum alloy casting, and improving the processing quality of the aluminum alloy casting;

[0038] After the die-casting mold B6 is connected to the die-casting mold A3, the aluminum alloy casting material enters the inside of the die-casting mold B6 and the die-casting mold A3 through the injection port 7 on the surface of the die-casting mold B6. Then, an external water pipe is connected to the outer frame 5, so that external water enters the cooling cavity B24 in the outer frame 5. Then, the heat in the die-casting mold A3 is transferred outward through the heat conducting layer B26, and the water in the cooling cavity absorbs the heat. At the same time, the refrigeration sheet 21 in the outer frame 5 is a semiconductor refrigeration sheet 21, which conveys the cold quantity to the cooling cavity A23, and the cooling cavity A23 conveys the cold quantity to the cooling cavity B24, so that the water in the cooling cavity B24 remains in a low temperature state, and the external structure of the die-casting mold B6 is the same as the external structure of the die-casting mold A3, thereby facilitating the cooling treatment of the aluminum alloy casting in the die-casting mold A3 and the die-casting mold B6 and improving the processing efficiency of the aluminum alloy casting;

[0039] After the aluminum alloy casting in the die-casting mold A3 and the die-casting mold B6 is formed, an external controller causes the electric push rod 20 in the frame 1 to drive the placement frame 18 to move, so that the placement frame 18 moves below the die-casting mold A3 and the die-casting mold B6. Subsequently, the formed aluminum alloy casting enters the placement frame 18, and the foam board 19 in the placement frame 18 conducts buffering treatment on the entering aluminum alloy casting, thereby facilitating the collection treatment of the formed aluminum alloy casting;

[0040] When the refrigerating sheet 21 inside the outer frame 5 works, the fan blades in the fan 22 on the surface of the outer frame 5 rotate at high speed, so that the heat of the refrigerating sheet 21 is dissipated.

[0041] When the piston block 27 enters the through hole 25 formed in the die-casting mold A3, the inner side of the through hole 25 fits with the outside of the piston block 27, which is convenient for the piston block 27 to enter the inside of the through hole 25.
