Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a high-temperature cleaning device for residual sand in casting molds. Background Technology

[0002] A casting mold is a tool used to create a part's structural shape in advance using other easily formable materials. The mold is then placed in a sand mold, creating a cavity in the sand mold that matches the dimensions of the part. A fluid liquid is then poured into this cavity, and after the liquid cools and solidifies, a part with the exact same shape and structure as the mold is formed.

[0003] Sometimes, after use, casting molds produce residues that are difficult to remove. If these residues are not removed, they can damage the parts that are subsequently cast. Therefore, a high-temperature cleaning device for residual sand in casting molds is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A high-temperature cleaning device for residual sand in casting molds includes: Fixture; A conveyor line, installed within the fixed frame, is used to transport casting molds; The striking hammer is fixedly installed on the top of the inner wall of the fixed frame and located above the conveyor line; The vibration assembly includes a drive unit located at the top of the fixed frame, multiple sets of springs disposed at the top of the drive unit, a movable frame fixedly disposed at the top of the multiple sets of springs, and a vibration machine mounted on the top of the movable frame. Both ends of the movable frame pass through the fixed frame and extend into the interior of the fixed frame. The two ends of the movable frame extending into the interior of the fixed frame are respectively located on both sides of the conveyor line. Both ends of the movable frame extending into the interior of the fixed frame are fixedly connected to a fixed plate. When the conveyor line transports the casting mold to below the hammer, the drive unit drives the moving frame to move upward, and lifts the casting mold through the fixed plate until it contacts the hammer, and starts the vibrator to clean the residual sand from the casting mold.

[0005] As an improvement to the above technical solution, the driving component includes electric push rods disposed on both sides of the top of the fixed frame, a movable plate is fixedly connected to the top of the electric push rod, and the top of the movable plate is fixedly connected to the spring.

[0006] As an improvement to the above technical solution, multiple sets of airflow pipes are fixedly inserted into the fixing frame and located around the striking hammer.

[0007] As an improvement to the above technical solution, an air storage ring is provided on the top of the fixing frame, the air storage ring is connected to the airflow pipe, and an air inlet pipe is provided on one side of the air storage ring.

[0008] As an improvement to the above technical solution, baffles are provided at the top of the fixed frame and at both ends along the extension direction of the conveyor line.

[0009] The beneficial effects of this utility model are: The high-frequency vibration generated by the vibrator, combined with the slight tapping action of the hammer, quickly loosens and removes residual sand from the surface and crevices of the mold, achieving a highly efficient and thorough sand removal effect. The mold adopts a "top-down" fixing structure, where the hammer presses the mold down from the top and the fixing plate lifts the mold from the bottom, ensuring the mold remains stable during vibration, preventing it from shifting or falling, and improving operational safety.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] A high-temperature cleaning device for residual sand in casting molds includes: Fixture 10; Conveyor line 20, installed inside the fixed frame 10, is used to convey casting molds; The hammer 11 is fixedly installed on the top of the inner wall of the fixed frame 10 and located above the conveyor line 20; The vibration assembly includes a drive unit located at the top of the fixed frame 10, multiple sets of springs 34 disposed at the top of the drive unit, a movable frame 30 fixedly disposed at the top of the multiple sets of springs 34, and a vibrator 32 mounted on the top of the movable frame 30. Both ends of the movable frame 30 penetrate the fixed frame 10 and extend into the interior of the fixed frame 10. The two ends of the movable frame 30 extending into the interior of the fixed frame 10 are respectively located on both sides of the conveyor line 20. Both ends of the movable frame 30 extending into the interior of the fixed frame 10 are fixedly connected to a fixing plate 31. When the conveyor line 20 transports the casting mold to below the hammer 11, the driving component drives the moving frame 30 to move upward, and lifts the casting mold through the fixing plate 31 until it contacts the hammer 11, and starts the vibrator 32 to clean the residual sand from the casting mold.

[0014] Specifically, the conveyor line 20 operates continuously, transporting the casting mold to be cleaned to the designated position directly below the hammer 11. At this point, the conveyor line 20 pauses, and the drive unit at the top of the fixed frame 10 is activated, pushing the moving frame 30 upward. The moving frame 30 supports the bottom sides of the mold via the fixed plates 31 at both ends, lifting the entire mold upward. Since the moving frame 30 is connected to the drive unit via multiple sets of springs 34, the springs provide cushioning during the lifting process, preventing rigid collisions from damaging the mold. As the moving frame 30 moves upward, the top of the mold gradually contacts the hammer 11 on the top of the inner wall of the fixed frame 10. At this point, the hammer 11 presses against the top of the mold, forming an "upper push, lower support" effect. The fixed state ensures the mold's stable position during vibration. After the mold is fixed, the vibrator 32 installed on the top of the moving frame 30 starts working, generating high-frequency vibration. The vibration is transmitted to the mold through the moving frame 30 and the fixed plate 31, causing the residual sand on the mold surface and in the gaps to loosen due to the vibration. At the same time, the contact point between the hammer 11 and the top of the mold will produce a slight knocking effect under the vibration, further assisting the residual sand to fall off. After cleaning is completed, the drive component moves the moving frame 30 down, and the mold falls back onto the conveyor line 20. The conveyor line 20 continues to operate, sending out the cleaned mold. At the same time, the next mold to be cleaned enters the device, and the above process is repeated. When the vibrator 32 is working, the spring 34 absorbs part of the vibration energy through elastic deformation, preventing the vibration from being transmitted to the top of the fixed frame 10 and the drive component, and reducing equipment resonance loss.

[0015] In one embodiment, the driving component includes electric push rods 33 fixedly disposed on both sides of the top of the fixed frame 10. A movable plate 35 is fixedly connected to the top of the electric push rod 33, and the top of the movable plate 35 is fixedly connected to the spring 34. When the push rod of the electric push rod 33 extends, it can drive the movable plate 35 to move upward, thereby driving the movable frame 30 to move upward through the spring 34. When the push rod of the electric push rod retracts, the movable frame 30 is driven to move downward through the movable plate 35 and the spring 34.

[0016] In one embodiment, multiple sets of airflow pipes 12 are fixedly inserted into the fixing frame 10 and around the hammer 11. When the vibrator 32 starts working, high-pressure airflow is sprayed onto the mold surface through the airflow pipes 12. The vibrator 32 loosens the residual sand, and the airflow provides additional thrust to blow away the residual sand. The combination of the two can clean the adhesive residual sand that is difficult to remove by traditional vibration. The airflow spray can also cool the mold surface at the same time to prevent the residual sand from sticking together again due to high temperature.

[0017] In one embodiment, the top of the fixed frame 10 is provided with an air storage ring 13, which is connected to the airflow pipe 12. An air inlet pipe is connected to one side of the air storage ring 13. Compressed air output by the air compressor enters the air storage ring 13 through the air inlet pipe. The internal cavity of the air storage ring 13 serves as a temporary air storage tank to store a certain amount of compressed air. When multiple sets of airflow pipes 12 are opened at the same time, the pre-stored gas in the air storage ring 13 can be quickly replenished.

[0018] In one embodiment, baffles 14 are provided at the top of the fixed frame 10 and at both ends along the extension direction of the conveyor line 20. When the moving frame 30 drives the fixed plate 31 to move the casting mold upward, the baffles 14 can hold the casting mold at both ends to prevent the casting mold from falling off during vibration.

[0019] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
