Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to a lifting ring casting machine. Background Technology

[0002] Shock absorbers are important cushioning structures inside automobiles, mitigating bumps and vibrations while driving. Shock absorber rings are an essential component of shock absorbers, facilitating the connection between the shock absorber and external structures. Shock absorber rings mainly consist of the ring section and the main body section.

[0003] Currently, the production of shock absorber lifting rings mainly involves the independent casting of the lifting ring section and the main body section. These are done on two separate casting machines using specific molds to produce blanks, which are then finely processed. This method generally results in low equipment utilization. Furthermore, most equipment lacks an automatic unloading mechanism for material removal after casting, still requiring manual prying. This manual prying involves exposure to high temperatures, high dust levels, and heat radiation, posing significant risks to the occupational health and safety of operators.

[0004] On December 22, 2022, the applicant filed a utility model patent application with authorization announcement number CN219112878U, disclosing a lifting ring casting machine. Specifically, the machine includes a frame with a control device mounted on it. The frame also includes a first casting mechanism and a second casting mechanism. The first casting mechanism has a first mold that can be opened and closed, used for forming the lifting ring portion. The second casting mechanism has a second mold that can be opened and closed, used for forming the main body portion. A discharge drive is provided between the second casting mechanism and the frame. The unloading drive can drive the second casting mechanism to rotate. The frame is provided with a first limiting member and a second limiting member to support the second casting mechanism in the state before and after rotation. The frame is provided with two material discharge ports in the inner areas of the first limiting member and the second limiting member, respectively. When the second casting mechanism abuts against the first limiting member, the second mold and the first mold can form a cavity that is aligned and connected to each other. The top of the cavity is provided with an opening for material injection. When the unloading drive drives the second casting mechanism to rotate and abut against the second limiting member, it can cooperate with the opening action of the second mold to complete the unloading. By setting a first casting mechanism and a second casting mechanism on the frame, a first mold and a second mold that can be opened and closed are respectively provided. The second casting mechanism is connected to an unloading drive component. The unloading drive component can drive the second casting mechanism to rotate. Before rotating, the second casting mechanism can be attached to the top of the first casting mechanism. The second mold is tightly attached to the top of the first mold to form a connected cavity, which can be used for synchronous casting. After cooling and forming, the unloading drive component drives the second casting mechanism to rotate, separating the first mold and the second mold. The workpieces on the first mold and the second mold can be unloaded independently and automatically.

[0005] However, when liquid aluminum alloy is injected into the mold cavity under low pressure, due to the complex structure inside the mold cavity, the liquid aluminum alloy cannot completely fill the mold cavity, resulting in casting defects such as incomplete filling, shrinkage cavities, cold shuts, hot cracks, and shrinkage cracks, causing the cast products to be unqualified.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] The embodiment of this utility model is as follows:

[0024] refer to Figures 1 to 6As shown, a lifting ring casting machine includes a frame 1, a control system, a support platform 2, a first casting mechanism 3, a second casting mechanism 4, a lifting mechanism 5, and a cooling mechanism 6. The length and width of the frame 1 are defined as the transverse direction, and the height of the frame 1 is defined as the vertical direction. The support platform 2 is mounted on the frame 1, with one end hinged to the frame 1 and the other end connected to the frame 1 via the lifting mechanism 5. The lifting mechanism 5 includes two first linear drive devices 51, two swing arms 52, and two connecting rods. The upper ends of both swing arms 52 are provided with sliding grooves 54, and both swing arms 52 are connected to the frame 1 by round pins passing through the sliding grooves 54. The two connecting seats 53 are respectively hinged to the lower ends of the two swing arms 52, and the lower ends of the two connecting seats 53 are locked to the support platform 2. The two ends of the first linear drive device 51 are respectively hinged to the middle of the frame 1 and the swing arms 52. The first casting mechanism 3 is located on the support platform 2 on the lateral side away from the lifting mechanism 5. The first casting mechanism 3 is provided with a first mold (not shown in the figure) that can be opened and closed. The first mold is used for forming the lifting ring part. The second casting mechanism 4 is located on the support platform 2 on the lateral side near the lifting mechanism 5. The second casting mechanism 4 is equipped with a second mold (not shown in the figure) that can be opened and closed. The second mold is used for forming the main body part. A discharge drive 7 is provided between the second casting mechanism 4 and the frame 1. The discharge drive 7 can drive the second casting mechanism 4 to rotate. The support platform 2 is equipped with a first limiting member 8 and a second limiting member 9 for supporting the second casting mechanism 4 before and after rotation. 2. Two material discharge ports 10 are respectively provided in the inner areas of the first limiting member 7 and the second limiting member 8. When the second casting mechanism 4 abuts against the first limiting member 8, the second mold and the first mold can form a cavity that is aligned and connected to each other. The top of the cavity is provided with an opening for material injection. When the unloading drive member 7 drives the second casting mechanism 4 to flip and abut against the second limiting member 8, it can cooperate with the opening action of the second mold to complete the unloading. The cooling mechanism 6 is provided on the frame 1 and distributed on the upper side of the first casting mechanism 3 and the second casting mechanism 4.

[0025] This lifting ring casting machine, through the setting of a lifting mechanism, utilizes a first linear drive device 51, a swing arm 52, and a connecting seat 53 to flexibly adjust the angle of the support platform 2. After casting in the first and second molds, the lifting mechanism adjusts the angle of the support platform 2, thereby driving the first and second molds to swing, allowing the liquid aluminum alloy to fully fill the mold cavity, reducing casting defects such as incomplete filling, shrinkage cavities, cold shuts, thermal cracks, and shrinkage cracks, and improving the quality of the cast products. The first casting mechanism 3 and the second casting mechanism 4 are respectively equipped with the first mold and the second mold, which can simultaneously form the lifting ring part and the main body part, improving production efficiency. The unloading drive component 7 drives the second casting mechanism 4 to rotate, and cooperates with the opening action of the second mold to complete the unloading, realizing automatic unloading, reducing manual operation, and reducing the occupational health and safety hazards to operators. The cooling mechanism 6 is located on the upper side of the first casting mechanism 3 and the second casting mechanism 4, which can cool the cast products in time, improving production efficiency.

[0026] Specifically, the cooling mechanism 6 includes a fan 61, a fan shroud 62, a second linear drive device 63, a first connecting rod 64, a second connecting rod 65, and a baffle 66. The fan shroud 62 covers the output end of the fan 61 and has an air outlet 621. The baffle 66 is distributed at the air outlet 621. One end of the first connecting rod 64 is fixedly connected to the baffle 66, and the other end of the first connecting rod 64 is hinged to the output end of the second linear drive device 63. Both ends of the second connecting rod 65 are respectively hinged to the middle of the first connecting rod 64 and the outer shell of the second linear drive device 63. The second linear drive device 63 drives the baffle 66 to swing, thereby adjusting the airflow direction and flow rate of the air outlet 621. This allows for precise control of the cooling effect according to different casting conditions and product requirements, further optimizing product quality and avoiding casting defects caused by uneven cooling.

[0027] In this embodiment, the first linear drive device 51 and the second linear drive device 63 are hydraulic cylinders, pneumatic cylinders or electric cylinders, preferably pneumatic cylinders.

[0028] In this embodiment, the first casting mechanism 3 includes a first fixed frame 31 fixed on the support platform 2. The first fixed frame 31 is provided with multiple parallel first guide rods 32. A first movable frame 33 is connected to the first guide rods 32. The first movable frame 33 is connected to a first opening and closing drive component 34, which is a cylinder, so that the first movable frame 33 can slide back and forth along the first guide rods 32. A cavity is formed between the first fixed frame 31 and the first movable frame 33. The first mold is located in the cavity, realizing the opening and closing control of the first mold of the first casting mechanism 3. This allows the first movable frame 33 to slide back and forth along the first guide rods 32, thereby realizing the opening and closing control of the first mold. The structure is simple and reliable, easy to operate, and convenient for the molding and casting of the lifting ring part. It can also ensure the stability and accuracy of the mold opening and closing, which is beneficial to improving product quality.

[0029] Furthermore, the cavity is equipped with a discharge pusher plate 11 capable of lateral displacement. The discharge pusher plate 11 is connected to a pusher plate drive component 12, which is a cylinder. After casting is completed, the discharge pusher plate 11 can be driven by the pusher plate drive component 12 to push the formed product out of the cavity, thereby achieving automatic unloading, improving unloading efficiency, reducing manual operation, reducing labor intensity, and avoiding damage to the product that may be caused by manual unloading, thus ensuring product quality.

[0030] Furthermore, a lifting plate 13 is provided at the bottom of the cavity, and the lifting plate 13 is connected to a lifting drive component 14, which is a cylinder. During the casting process, the height of the lifting plate 13 can be adjusted as needed to assist in product molding and ensure the dimensional accuracy of each part of the product. During unloading, the lifting plate 13 can rise under the action of the lifting drive component 14 to lift the product, and cooperate with the unloading push plate 11 to push the product out more smoothly, further improving unloading efficiency and product quality.

[0031] In this embodiment, the unloading drive 7 is fixed on the support platform 2, and its output end is provided with a flipping frame 15. The second casting mechanism 4 is fixed on the flipping frame 15. This structure enables the unloading drive 7 to stably drive the second casting mechanism 4 to flip, ensuring the smoothness and accuracy of the flipping action. This ensures the separation of the second mold from the first mold and the smooth progress of the unloading process, reduces mold damage or product damage caused by unstable flipping, and improves the reliability of equipment operation and product quality.

[0032] Furthermore, the second casting mechanism 4 includes a second fixed frame 41 and a second movable frame 42. The second fixed frame 41 is fixed with multiple parallel second guide rods 43. The second movable frame 42 is connected to a second opening and closing drive member 44, which enables the second movable frame 42 to reciprocate along the second guide rods 43. The second mold is located between the second fixed frame 41 and the second movable frame 42, realizing the opening and closing control of the second mold of the second casting mechanism 4. The second movable frame 42 can reciprocate along the second guide rods 43 to realize the opening and closing control of the second mold. The structure is similar to that of the first casting mechanism 3 but operates independently. It can accurately control the molding and casting process of the main body, ensure the dimensional accuracy and quality of the main body, and cooperate with the first casting mechanism 3 to improve the casting quality of the entire shock absorber lifting ring.
