Description

Technical Field

[0001] The invention relates to the technical field of metal casting, in particular to a metal casting forming mechanism and a use method thereof. Background Art

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. The camshaft is generally formed by casting. Casting is the process of pouring liquid metal into a casting cavity that matches the shape of the part, and then cooling and solidifying it to obtain a part or blank. When an enterprise casts a camshaft, it often needs to use a metal casting molding mechanism (equipment).

[0003] For example, a Chinese invention patent with authorization announcement number: CN117773082B discloses a camshaft casting equipment, including a casting equipment body, a limiting positioning frame is fixedly provided on the upper end of the casting equipment body, and mounting movable holes are symmetrically opened on both sides of the limiting positioning frame, and a matching limiting hole is opened on the end surface of one end of the casting equipment body, and a vertical bearing connecting plate is fixedly provided on the casting equipment body on the upper side of the matching limiting hole, the positioning of the lower mold body is achieved by the limiting positioning frame, and the positioning of the upper mold is achieved by installing a connecting support plate, when the upper mold body and the lower mold body are closed together, the lower mold body can be automatically fixedly installed on the casting equipment body, and the upper mold body can be fixedly installed on the hydraulic rod to ensure the safe use of both, and when the hydraulic rod does not drive the upper mold body to move downward, the lower mold body and the upper mold body are respectively in an unlocked state, and can be quickly disassembled.

[0004] The existing camshaft casting equipment has a single workstation and low continuity. In the actual casting process, the upper and lower molds are generally closed first, and then the molten metal is poured into the molding cavity that is adapted to the shape of the camshaft at the middle position of the upper and lower molds. After the camshaft is solidified, it can be a camshaft casting. After the camshaft is cast, the upper and lower molds need to be separated to facilitate the unloading of the cast camshaft. This operation method will cause the molten metal casting and the unloading of the casting to interfere with each other, greatly affecting the continuity and efficiency of the camshaft casting, and is not convenient for automatic unloading. It often requires staff to operate to unload, which increases the labor intensity of the staff and reduces the production effect. Summary of the invention

[0019] Preferably, a material discharge notch is provided on the top of the frame, and a grid collection frame is provided below the frame and at a position corresponding to the material discharge notch.

[0020] The present invention also provides a method for using the metal casting molding mechanism, using the above metal casting molding mechanism, comprising the following steps:

[0021] S1. First, start the driving component to make it operate continuously. The driving component drives the mounting ring to operate intermittently. When the driving component drives the upper mold body and the lower mold body in the closed state to move to the bottom of the injection molding device, the mounting ring stops rotating (the driving component still keeps the running state). At this time, the mounting ring is limited and stopped by the stop component and the cam. Then, the molten metal is injected into the casting port on the upper mold body through the injection molding device. The molten metal flows into the molding cavity between the upper mold body and the lower mold body along the casting port.

[0022] S2. After the metal liquid is cast, the driving assembly drives the mounting ring to rotate again, driving the upper mold body and the lower mold body with the metal liquid cast to rotate and move in the direction close to the driving separation arc-shaped outer rack, and synchronously drives the upper mold body and the lower mold body after unloading to move in the direction of the injection molding equipment to cast the metal liquid. During the metal liquid casting process of the mold, the metal liquid inside the previous mold with the metal liquid cast can solidify and form;

[0023] S3. After the metal liquid in the mold is solidified and formed, the driving component continues to drive the mold to move and drive the opening and closing component to move synchronously. When the opening and closing component moves to a position corresponding to the driving separation arc-shaped outer rack, the opening and closing component and the driving separation arc-shaped outer rack are used in conjunction to drive the upper mold body to move upward, so that it is separated from the lower mold body, so as to facilitate the subsequent unloading of castings;

[0024] S4. After separation, the upper mold body and the lower mold body continue to rotate and move, synchronously driving the flip assembly to move. When the flip assembly moves to a position corresponding to the arc-shaped outer rack driving the flip, the arc-shaped outer rack driving the flip is used in conjunction with the flip assembly to drive the upper mold body and the lower mold body to flip 90°, so that they are in a horizontal state for automatic unloading. At this time, the mounting ring is in a stopped rotation state again. If, under special circumstances, the casting is too tightly attached to the mold and cannot be automatically detached, manual assistance can be used to help it detach from the mold to achieve unloading. The casting detached from the mold passes through the unloading gap through its own gravity and falls into the grid collection frame for unified collection.

[0025] S5, when the casting in step S3 is being unloaded, one set of the upper mold body and the lower mold body is just located directly below the injection molding device, and the molten metal can be cast, ensuring that the unloading of the casting and the molten metal casting operations do not interfere with each other;

[0026] S6, the driving component drives the upper mold body and the lower mold body to continue to rotate and move after unloading, and drives the flip arc outer rack to cooperate with the flip component to drive the upper mold body and the lower mold body to flip 270° for reset. When the upper mold body and the lower mold body in the separated state rotate and move to the position corresponding to the driving closed arc inner rack, the driving closed arc inner rack is used in cooperation with the opening and closing component to drive the upper mold body to move downward to close it with the lower mold body, so as to facilitate the next metal liquid casting;

[0027] S7, the driving assembly drives the closed upper mold body and the lower mold body to continue to rotate and move in the direction of the injection molding device until they move to the bottom of the injection molding device. At this time, the upper mold body and the lower mold body stop rotating (the driving assembly remains in operation) to facilitate the next metal liquid casting;

[0028] S8. When the driving component is running, the cooling component can be driven to operate synchronously to blow air to the grid collection frame, thereby accelerating the air flow rate around the grid collection frame and cooling the castings collected in the grid collection frame.

[0029] The present invention has the following beneficial effects:

[0030] The present invention arranges three groups of upper and lower mold bodies. While one group of the upper and lower mold bodies is performing molten metal casting, the other two groups of the upper and lower mold bodies are respectively performing solidification molding of the molten metal and unloading of the casting after solidification molding, thereby ensuring that the unloading of the casting and the molten metal casting operations do not interfere with each other, thereby improving the continuity and efficiency of the casting equipment production.

[0031] The present invention uses an opening and closing component in conjunction with a driving and separating arc-shaped outer rack, and can automatically separate the upper and lower mold bodies when the driving component drives the mold to move toward the lower material notch position, so as to facilitate subsequent unloading operations on the casting in the mold.

[0032] The present invention uses a flip assembly and a driving flip arc-shaped external rack to automatically flip the separated upper and lower mold bodies by 90 degrees when the driving assembly drives the mold to move to the lower material notch position, so as to pour out the product after casting in the mold, realize automatic unloading of the casting, greatly improve the automation degree of the casting molding equipment, and reduce the labor intensity of the staff. After unloading, the upper and lower mold bodies are driven to flip 270 degrees again for reset, so that the casting port on the mold returns to the upward state, so as to facilitate the subsequent casting of molten metal.

[0033] The invention uses the opening and closing component and the driving closed arc-shaped outer rack in coordination, and can automatically close the upper and lower mold bodies when the driving component drives the mold to move to the position of the injection molding device, so as to facilitate the next metal liquid casting.

[0034] After the present invention has been used for a period of time and its rubber stop block is worn, the staff drives the second threaded rod to move the second threaded block in the slide groove toward the side close to the mounting ring, thereby driving the rubber stop block to move synchronously and adjusting the position of the rubber stop block so that after the rubber stop block is worn, it can be adjusted to the side close to the mounting ring to ensure that there is a sufficiently large friction force between the rubber stop block and the protrusion, thereby ensuring the stopping effect on the mounting ring and avoiding the stopping effect on the mounting ring being affected due to the reduction of friction force between the rubber stop block and the protrusion after the rubber stop block is worn.

[0076] A material discharge notch 20 is provided on the top of the frame 1 , and a grid collecting frame 21 is provided below the frame 1 and at a position corresponding to the material discharge notch 20 .

[0077] The present invention also provides a method for using the metal casting molding mechanism, using the above metal casting molding mechanism, comprising the following steps:

[0078] S1. Start the driving assembly 9 first to make it operate continuously. The output end of the driving motor 901 rotates to drive the rotating shaft 4 903 to rotate, and then drives the residual gear 904 to rotate. During the process of the residual gear 904 rotating one circle, when the teeth on the residual gear 904 rotate to mesh with the gear 4 906, the gear 4 906 can be driven to rotate, and the teeth in the 120° range on the residual gear 904 just drive the gear 4 906 to rotate one circle, and the gear 4 906 rotates through the rotating shaft 3 902 to drive the gear 3 905 to rotate one circle synchronously, and the gear 3 905 rotates one circle to drive the gear ring 907 to rotate 120°, thereby realizing the switching of the positions of the three groups of upper mold bodies 8 and lower mold bodies 6. When the residual gear 904 is disengaged from the gear 4 906, the mounting ring 3 stops rotating, thereby realizing the intermittent driving of the mounting ring 3 by the driving assembly 9 to rotate and move, and the driving assembly 9 drives the upper mold body 8 and the lower mold 6 in the closed state. When the mold body 6 moves to the bottom of the injection molding device 17, the mounting ring 3 stops rotating (the residual gear 904 and the gear four 906 are in a separated state, and the driving assembly 9 is still in operation). At this time, one of the cams is just opposite to the rubber stop block 1504 in the stop assembly and abuts against each other. The mounting ring 3 is limited and stopped by the friction between the rubber stop block 1504 and the cam to prevent the residual gear 904 from being disengaged from the gear four 906. The mounting ring 3 continues to rotate and move due to inertia, thereby ensuring that one of the upper mold bodies 8 and the lower mold body 6 can stably stop directly below the injection molding device 17, which is convenient for the subsequent injection molding device 17 to cast molten metal into the mold, and then the molten metal is injected into the casting port 19 on the upper mold body 8 through the injection molding device 17. The molten metal flows into the molding cavity 18 between the upper mold body 8 and the lower mold body 6 along the casting port 19;

[0079] S2. After the molten metal casting is completed, the driving assembly 9 drives the mounting ring 3 to rotate again, driving the upper mold body 8 and the lower mold body 6 with the molten metal casted therein to rotate and move in the direction close to the driving separation arc-shaped outer rack 12, and synchronously driving the upper mold body 8 and the lower mold body 6 after unloading to move in the direction of the injection molding device 17 to cast the molten metal thereon. During the molten metal casting process of the mold, the molten metal inside the previous mold with the molten metal casted therein can solidify and form;

[0080] S3. After the metal liquid in the mold is solidified and formed, the driving component 9 continues to drive the mold to move and drive the opening and closing component 7 to move synchronously. When the opening and closing component 7 moves to the position corresponding to the driving separation arc-shaped outer rack 12, at this time, the gear 1 706 in the opening and closing component 7 moves to the driving separation arc-shaped outer rack 12 to engage. Then, during the rotation movement of the gear 1 706, the gear 1 706 cooperates with the driving separation arc-shaped outer rack 12 to make the gear 1 706 rotate while revolving, thereby driving the rotating shaft 1 702 and the threaded rod 1 704 to rotate synchronously, and under the limiting effect of the guide rod 701 and the guide ring 703 on the upper mold body 8, the upper mold body 8 is driven to move upward through the threaded block 1 705, so that it is separated from the lower mold body 6, so as to facilitate the subsequent unloading of the casting;

[0081] S4. After separation, the upper mold body 8 and the lower mold body 6 continue to rotate and move (the gear 1 706 is separated from the driving separation arc-shaped outer rack 12), and synchronously drive the flip assembly 5 to move. When the gear 2 504 in the flip assembly 5 moves to the position corresponding to the driving flip arc-shaped outer rack 11 (the gear 2 504 is meshed with the driving flip arc-shaped outer rack 11), the driving flip arc-shaped outer rack 11 cooperates with the gear 2 504, so that the gear 2 504 revolves and rotates at the same time, and drives the rotating shaft 2 502 and the worm 505 to rotate synchronously, thereby driving the worm wheel 503 meshed with the worm 505 to rotate. , and drives the support shaft 501 fixed with the lower mold body 6 to rotate 90°, thereby driving the upper mold body 8 and the lower mold body 6 to turn over 90° synchronously, so that they are in a horizontal state for automatic unloading, which improves the automation degree of the equipment, reduces the labor intensity of the staff, and improves the production efficiency. At this time, the mounting ring 3 is in a stopped rotation state again. If the casting is too tightly attached to the mold and cannot be automatically separated under special circumstances, it can be manually detached from the mold through auxiliary tools to achieve unloading. The casting separated from the mold passes through the unloading gap 20 through its own gravity and falls into the grid collection frame 21 for unified collection;

[0082] S5, when the casting in step S3 is being unloaded, one set of the upper mold body 8 and the lower mold body 6 is just located directly below the injection molding device 17, and the molten metal can be poured, ensuring that the unloading of the casting and the molten metal pouring operations do not interfere with each other;

[0083] S6, the driving component 9 drives the upper mold body 8 and the lower mold body 6 to continue rotating and moving after unloading, and drives the flip arc outer rack 11 to cooperate with the flip component 5 to drive the upper mold body 8 and the lower mold body 6 to flip 270° for reset. When the upper mold body 8 and the lower mold body 6 in the separated state rotate and move to the position corresponding to the driving closed arc inner rack 13, the driving closed arc inner rack 13 is used in cooperation with the opening and closing component 7 to drive the upper mold body 8 to move downward to close it with the lower mold body 6, so as to facilitate the next metal liquid casting;

[0084] S7, the driving assembly 9 drives the closed upper mold body 8 and the lower mold body 6 to continue to rotate and move in the direction of the injection molding device 17 until they move to the bottom of the injection molding device 17. At this time, the upper mold body 8 and the lower mold body 6 stop rotating (the driving assembly 9 remains in operation) to facilitate the next metal liquid casting;

[0085] S8, while the driving component 9 is running, the cooling component 10 can be driven to operate synchronously, blowing air to the grid collection frame 21, accelerating the air flow rate around the grid collection frame 21, and cooling the castings collected in the grid collection frame 21;

[0086] S9. After the rubber stop block 1504 is worn out after being used for a period of time, the staff drives the second threaded block 1503 to move in the slide groove 1501 toward the side close to the mounting ring 3 by rotating the second threaded rod 1502, thereby driving the rubber stop block 1504 to move synchronously, and adjust the position of the rubber stop block 1504 so that after the rubber stop block 1504 is worn out, it can be adjusted to the side close to the mounting ring 3 to ensure that there is sufficient friction between the rubber stop block 1504 and the protrusion 14, thereby ensuring the stopping effect on the mounting ring 3 and avoiding the stopping effect on the mounting ring 3 being affected due to the reduced friction between the rubber stop block 1504 and the protrusion 14 after being worn out.

[0087] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the cooling component 10 includes a support frame 1001 fixedly installed on the bottom of the frame 1, and a rotating shaft 1002 is rotatably installed on the support frame 1001. The two ends of the rotating shaft 1002 are respectively fixedly connected with fan blades 1003 and bevel gears 1004. The outer surface of the bevel gear 1004 is meshed with a toothed disc 1005, and the toothed disc 1005 is fixedly sleeved on the outer surface of the rotating shaft 4 903. A grid protective cover 1006 is also fixedly connected to the support frame 1001, and the grid protective cover 1006 is arranged on the outside of the fan blades 1003. The setting of the grid protective cover 1006 can shield and protect the fan blades 1003 to prevent the fan blades 1003 from accidentally touching other objects and causing damage during rotation.

[0088] When the driving component 9 is operating, the toothed disc 1005 can be driven to rotate, thereby driving the bevel gear 1004 meshing therewith to rotate, and driving the fan blades 1003 to rotate through the rotating shaft 903, blowing air to the grid collection frame 21, accelerating the air flow rate around the grid collection frame 21, and achieving air blowing and cooling treatment for the castings collected in the grid collection frame 21, thereby improving the cooling efficiency of the castings.

A method for using a metal casting molding mechanism, based on the metal casting molding mechanism according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1, first start the driving component (9) to make it operate continuously, the driving component (9) drives the mounting ring (3) to operate intermittently, when the driving component (9) drives the upper mold body (8) and the lower mold body (6) in the closed state to move to the bottom of the injection molding device (17), the mounting ring (3) stops rotating, at this time, the mounting ring (3) is limited and stopped by the stop component and the cam, and then the molten metal is injected into the casting port (19) on the upper mold body (8) through the injection molding device (17), and the molten metal flows into the molding cavity (18) between the upper mold body (8) and the lower mold body (6) along the casting port (19); S2. After the molten metal is cast, the driving assembly (9) drives the mounting ring (3) to rotate again, driving the upper mold body (8) and the lower mold body (6) cast with the molten metal to rotate and move in a direction close to the driving separation arc-shaped outer rack (12), and simultaneously driving the upper mold body (8) and the lower mold body (6) after unloading to move in the direction of the injection molding device (17) to cast the molten metal. During the molten metal casting process of the mold, the molten metal inside the previous mold cast with the molten metal can solidify and form; S3. After the metal liquid in the mold is solidified and formed, the driving component (9) continues to drive the mold to move, driving the opening and closing component (7) to move synchronously. When the opening and closing component (7) moves to a position corresponding to the driving separation arc-shaped outer rack (12), the opening and closing component (7) and the driving separation arc-shaped outer rack (12) are used in conjunction with each other to drive the upper mold body (8) to move upward, so that it is separated from the lower mold body (6) to facilitate the subsequent unloading of the casting; S4, the upper mold body (8) and the lower mold body (6) continue to rotate and move after separation, synchronously driving the flip assembly (5) to move. When the flip assembly (5) moves to a position corresponding to the driving flip arc-shaped outer rack (11), the driving flip arc-shaped outer rack (11) cooperates with the flip assembly (5) to drive the upper mold body (8) and the lower mold body (6) to flip 90°, so that they are in a horizontal state for automatic unloading. The castings separated from the mold pass through the unloading gap (20) under the action of their own gravity and fall into the grid collection frame (21) for unified collection; S5, when the casting in step S3 is being unloaded, one set of the upper mold body (8) and the lower mold body (6) is located just below the injection molding device (17), and the molten metal can be poured, ensuring that the unloading of the casting and the molten metal pouring operations do not interfere with each other; S6, the driving component (9) drives the upper mold body (8) and the lower mold body (6) to continue rotating and moving after unloading, and drives the flip arc outer rack (11) to cooperate with the flip component (5) to drive the upper mold body (8) and the lower mold body (6) to flip 270 degrees for reset. When the upper mold body (8) and the lower mold body (6) in the separated state rotate and move to a position corresponding to the driving closed arc inner rack (13), the driving closed arc inner rack (13) is used in cooperation with the opening and closing component (7) to drive the upper mold body (8) to move downward so that it is closed with the lower mold body (6) to facilitate the next metal casting; S7, the driving assembly (9) drives the closed upper mold body (8) and the lower mold body (6) to continue rotating and moving in the direction of the injection molding device (17) until they are moved to the bottom of the injection molding device (17). At this time, the upper mold body (8) and the lower mold body (6) stop rotating to facilitate the next metal liquid casting; S8. When the driving component (9) is running, the cooling component (10) can be driven to operate synchronously to blow air toward the grid collection frame (21), thereby accelerating the air flow rate around the grid collection frame (21) and cooling the castings collected in the grid collection frame (21).
