Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a biomimetic honeycomb skeleton embedded sand mold structure. Background Technology

[0002] Sand mold structure is a casting mold structure made of molding sand in the casting process. It consists of sand box, cavity, core, gating, etc. The molding sand is compacted to form a cavity that matches the shape of the casting. The core is used to form the inner cavity of the casting. The gating guides the molten metal to flow in. It is low in cost, highly adaptable, and can produce castings with complex shapes. It is widely used in steel and non-ferrous metal casting and is the core process structure of traditional casting. The biomimetic honeycomb skeleton embedded sand box is an innovative design of casting sand box that draws on the mechanical properties of honeycomb structure. The honeycomb skeleton is embedded in the sand box body. This structure can enhance the overall strength and deformation resistance of the sand box, while reducing its own weight, optimizing heat dissipation performance, and improving the compactness and stability of the molding sand. It is suitable for casting complex castings and can improve production efficiency and casting quality.

[0003] The steel bars used to fix the casting mold in the sand box are usually called "mold fixing bars" or "sand box tie bars". Their main function is to firmly connect the mold to the sand box, prevent the mold from shifting, deforming or floating during sand filling, compaction and pouring, and ensure the dimensional accuracy of the casting. At the same time, it can enhance the overall stability, resist the impact force and static pressure when the molten metal is injected, reduce the risk of sand mold collapse and mold cracking, and also assist in the quick positioning and installation of the mold, improve production efficiency. It is a key component to ensure the stability of the casting process and the quality of the casting.

[0004] However, while existing fixing ribs can be flexibly adjusted in position, they have obvious shortcomings. Not only is it difficult to balance disassembly and fixing stability, but they also cannot be fixed inside the sand box, resulting in low fastening effect. Furthermore, they cannot flexibly change the angle according to the mold shape and cavity structure, which makes them unsuitable for casting complex parts and restricts their application efficiency in diverse production scenarios. Therefore, we propose a biomimetic honeycomb skeleton embedded sand mold structure. Utility Model Content

[0005] The technical problem to be solved by this application is that although the existing fixing ribs can be flexibly adjusted in position, they have obvious shortcomings. Not only is it difficult to balance disassembly and fixing stability, but they also cannot be fixed inside the sand box, resulting in low fastening effect. Furthermore, they cannot flexibly change the angle according to the mold shape and cavity structure, which makes them less adaptable to the casting of complex castings and restricts their application effectiveness in diverse production scenarios.

[0006] To address the aforementioned technical problems, this application provides a biomimetic honeycomb skeleton embedded sand mold structure, comprising a sand box body, two auxiliary shafts arranged parallel to each other on both sides of the sand box body, a skeleton disposed inside the sand box body, and a limiting reinforcing rib assembly disposed on the skeleton, the limiting reinforcing rib assembly comprising a suspension rib and a limiting rib, the suspension rib and the limiting rib being threadedly connected for adjusting the angle of the limiting rib, and a fixing mechanism disposed on the suspension rib for fixing the limiting reinforcing rib assembly to the skeleton.

[0008] In some embodiments, a metal telescopic tube is provided on the limiting rib at the connection between the threaded rod and the limiting rib. The metal telescopic tube is sleeved on the outside of the threaded rod, and a slider is provided at the top end of the metal telescopic tube.

[0009] In some embodiments, the lower end of the suspension rib is provided with a movable groove outside the threaded groove, and the slider is rotatably connected to the movable groove.

[0010] In some embodiments, the suspension rib is U-shaped.

[0013] This utility model has at least the following beneficial effects: By splitting the limiting reinforcing rib assembly into two parts, a suspension rib and a limiting rib, a threaded groove is opened at the bottom of the suspension rib and a threaded rod is set at the top of the limiting rib. The connection between the suspension rib and the limiting rib is achieved through the cooperation of the threaded groove and the threaded rod.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a biomimetic honeycomb skeleton embedded sand mold structure, including a sand box body 1, two auxiliary shafts 11 are arranged parallel to each other on both sides of the sand box body 1, a skeleton 2 is arranged inside the sand box body 1, a limiting reinforcing rib assembly 3 is arranged on the skeleton 2, the limiting reinforcing rib assembly 3 includes a suspension rib 31 and a limiting rib 32, the suspension rib 31 and the limiting rib 32 are set to a threaded connection for adjusting the angle of the limiting rib 32, a fixing mechanism 4 is arranged on the suspension rib 31, the fixing mechanism 4 is used to fix the limiting reinforcing rib assembly 3 to the skeleton 2.

[0018] The limiting reinforcing rib assembly 3 is divided into two parts: a suspension rib 31 and a limiting rib 32. A threaded groove 311 is opened at the bottom of the suspension rib 31, and a threaded rod 321 is set at the top of the limiting rib 32. The connection between the suspension rib 31 and the limiting rib 32 is achieved through the cooperation of the threaded groove 311 and the threaded rod 321. During the connection process, the angle of the limiting rib 32 can be adjusted by rotating it, so that the application range of the limiting reinforcing rib assembly 3 is wider and it can be fixed at multiple angles. Two opposing fixing mechanisms 4 are set on the opposite side of the suspension rib 31. The function of the fixing mechanism 4 is to fix the limiting reinforcing rib assembly 3 to the frame 2, thereby preventing the frame 2 from shifting due to external forces during operation.

[0019] Example 2: Based on Example 1, as follows Figure 3 As shown, a threaded groove 311 is provided in the middle of the lower end of the suspension rib 31, and a threaded rod 321 is provided at the top of the limiting rib 32. The threaded rod 321 is threadedly connected to the inside of the threaded groove 311. A metal telescopic tube 33 is provided on the limiting rib 32 at the connection between the threaded rod 321 and the limiting rib 32. The metal telescopic tube 33 is sleeved on the outside of the threaded rod 321. A slider 331 is provided at the top of the metal telescopic tube 33. A movable groove 312 is provided at the lower end of the suspension rib 31 outside the threaded groove 311. The slider 331 is rotatably connected to the movable groove 312.

[0020] The suspension rib 31 and the limiting rib 32 are connected by the cooperation of the threaded groove 311 and the threaded rod 321, and a metal telescopic tube 33 is installed between them to form a complete limiting and reinforcing rib assembly 3. When the angle of the limiting rib 32 needs to be adjusted, the limiting rib 32 is rotated, and the threaded rod 321 will rotate inside the threaded groove 311. During this process, the limiting rib 32 will move downward, and the metal telescopic tube 33 will also be stretched synchronously. The metal telescopic tube 33 is rotatably connected to the suspension rib 31 through the slider 331. The slider 331 is installed inside the movable groove 312 at the bottom of the suspension rib 31, and the bottom end of the slider 331 is connected to the metal telescopic tube 33. With the rotation and downward extension of the limiting rib 32 and the rotation at the bottom of the suspension rib 31, the metal telescopic tube 33, with its metal material and corrugated pipe-like structural characteristics, can achieve the stretching action. It will not hinder the angle adjustment of the limiting rib 32, and can effectively prevent sand from getting stuck in the connection between the suspension rib 31 and the limiting rib 32, ensuring the normal operation of the assembly.

[0021] Example 3: Based on Example 1, such as Figure 5 As shown, the suspension rib 31 is U-shaped, and the fixing mechanism 4 includes two mounting grooves 41. The two mounting grooves 41 are respectively set on both sides inside the U-shaped structure. The two mounting grooves 41 are horizontally set. A gasket 42 is movably set at the opening of the mounting groove 41. One end of the gasket 42 located inside the mounting groove 41 is set as an inclined surface. A spring 43 is set between the gasket 42 and the inner wall of the mounting groove 41.

[0022] The suspension rib 31 adopts a U-shaped structure design, and its core function is to suspend it on the frame 2. On both sides of the interior of the suspension rib 31, there are mounting grooves 41. Inside each mounting groove 41, a washer 42 is connected via a spring 43. The side of the washer 42 connected to the spring 43 is machined into a bevel. When the spring 43 is in a naturally relaxed state, the bevel of the washer 42 is flush with the edge of the mounting groove 41. At this time, the lower side of the washer 42 is retracted into the mounting groove 41, while the upper side protrudes outside the mounting groove 41, thus suspending the suspension rib 31 to the frame 2. When the suspension rib 31 is placed on the frame 2, the initial gap between the two opposing pads 42 is relatively wide, so the suspension rib 31 can be directly placed on the frame 2 through the gap. When the suspension rib 31 is pressed down, the pads 42 protruding from the outside of the mounting groove 41 will be squeezed by the frame 2 and contract into the mounting groove 41. At the same time, the spring 43 is compressed inward under pressure. When the outer side of the pads 42 is parallel to the edge of the mounting groove 41, the spring 43 releases the stored pressure and pushes the pads 42 to fit tightly against the surface of the frame 2, thereby achieving a stable fixation of the limiting reinforcing rib assembly 3.

[0023] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, firstly, according to the mold fixing requirements, the limiting reinforcing rib assembly 3 is installed on the frame 2 through the fixing mechanism 4 on the suspension rib 31. During installation, using the U-shaped structure of the suspension rib 31, after aligning with the frame 2, press down. At this time, the protruding pad 42 in the mounting groove 41 is squeezed by the frame 2, shrinks into the mounting groove 41 and compresses the spring 43 until the outer side of the pad 42 is parallel to the edge of the mounting groove 41. The spring 43 releases pressure and pushes the pad 42 tightly against the frame 2, completing the fixing of the limiting reinforcing rib assembly 3. Subsequently, adjust according to the mold shape. Adjusting the angle of the limiting rib 32: Rotate the limiting rib 32 so that the threaded rod 321 at its top rotates in the threaded groove 311 at the bottom of the suspension rib 31. The limiting rib 32 moves downward with the rotation, and at the same time drives the metal telescopic tube 33 sleeved outside the threaded rod 321 to stretch. The metal telescopic tube 33 rotates in the movable groove 312 at the bottom of the suspension rib 31 through the slider 331 at its top. This does not hinder the adjustment of the angle of the limiting rib 32, and also prevents sand from entering the connection part. After the adjustment is completed, the limiting reinforcing rib assembly 3 can fix the mold firmly from multiple angles, prevent the skeleton 2 from shifting due to external force during operation, and ensure the stable progress of the sand mold casting process.
