Description

Technical Field

[0001] This utility model belongs to the field of casting mold technology, specifically a block-type combined sand core bottom mold base. Background Technology

[0002] In the casting process, the sand core mold base is a crucial component of the mold, and its structural design directly impacts the quality of the castings and production efficiency. Currently, most common sand core mold bases adopt an integral design. While this meets basic usage requirements, it has certain limitations in practical applications. For example, when a certain area wears or is damaged, the entire mold base often needs to be replaced, resulting in high maintenance costs and significant resource waste. Furthermore, the integral design lacks flexibility in adapting to sand cores of different sizes or shapes, making it difficult to quickly adjust to meet diverse production needs.

[0003] For example, some existing technologies improve the adaptability of the bottom mold base by adding complex adjustment mechanisms, but such designs usually lead to a more complex overall structure, increasing manufacturing difficulty and cost. The above indicates that existing sand core bottom mold bases still have room for improvement in terms of maintainability, economy, and adaptability.

[0004] Therefore, we have made improvements to this by proposing a modular sand core mold base. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of current sand core mold bases in terms of maintainability, economy, and adaptability, and to provide a modular sand core mold base that overcomes the problems of high maintenance costs, resource waste, and insufficient flexibility caused by the integral design in the prior art.

[0006] To achieve the aforementioned objectives and address the problems, this utility model provides a modular sand core mold base, comprising a base module, insert modules, and an adjustment module. The base module serves as the fundamental support component of the overall structure and has multiple receiving slots. The insert modules are embedded within these receiving slots and fit tightly with the base module. The adjustment module is located on the side of the base module and is used for fine-tuning the position of the insert modules. Through the combined use of the insert modules and the base module, independent replacement of localized areas and flexible adjustment of the overall structure are achieved.

[0007] The insert module includes a base block, a positioning pin, and an elastic gasket. A positioning hole is provided at the bottom of the base block, through which the positioning pin passes and is fixed within the receiving groove of the base module, thereby achieving precise positioning and connection between the insert module and the base module. The elastic gasket is located on the top surface of the base block and provides cushioning and sealing during the sand core forming process. The insert module is made of high-strength, wear-resistant material, effectively extending its service life.

[0008] As a preferred technical solution of this application, the base module includes a main frame and partition plates. The main frame is a rectangular structure with multiple horizontal and vertical partition plates inside, dividing the main frame into several evenly distributed receiving slots. The thickness of the partition plates is optimized to ensure the strength of the overall structure while reducing the amount of material used. Each receiving slot has a guide groove machined on its inner wall to guide the installation direction of the insert module.

[0009] As a preferred technical solution of this application, the adjustment module includes an adjustment screw, a limiting block, and a handwheel. One end of the adjustment screw passes through the side wall of the base module and contacts the side of the insert module, while the other end is fixedly connected to the handwheel. By rotating the handwheel, the adjustment screw pushes the insert module to move along the guide groove, thereby achieving precise adjustment of the insert module's position. The limiting block is fixed to the middle of the adjustment screw to limit the range of movement of the adjustment screw and prevent excessive adjustment from causing the insert module to disengage from the receiving groove.

[0010] As a preferred technical solution of this application, the insert module further includes a locking device for fixing the position of the insert module after adjustment. The locking device includes a locking bolt and a pressure plate. The pressure plate is located on top of the insert module and is fixedly connected to the base module by the locking bolt. When the locking bolt is tightened, the pressure plate applies downward pressure to the insert module to ensure that the insert module remains stable during operation.

[0011] As a preferred technical solution of this application, the bottom of the base module is provided with a shock-absorbing pad layer. The shock-absorbing pad layer is made of rubber material, which has good elasticity and wear resistance, and can absorb vibration during the casting process and protect the base module from damage. The shock-absorbing pad layer is fixed to the bottom surface of the base module by adhesive bonding, and its thickness is adjusted according to the actual working conditions.

[0012] As a preferred technical solution of this application, the top surface of the substrate block of the insert module is provided with anti-slip texture. The anti-slip texture is distributed in a grid pattern to increase the friction between the substrate block and the sand core, preventing the sand core from sliding during the molding process. The depth and spacing of the anti-slip texture are calculated and optimized to balance friction performance and ease of cleaning.

[0013] As a preferred technical solution of this application, the adjustment module further includes a dial for displaying the rotation angle of the adjustment screw. The dial is fixed to the outer surface of the handwheel and is marked with precise scale lines. By observing the values ​​on the dial, the operator can accurately grasp the adjustment amount of the insert module, improving the adjustment accuracy.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the combined structure of insert modules and base modules solves the problem of needing to replace the entire base when traditional integral sand core mold bases experience localized wear or damage. The independent design of the insert modules makes replacement of localized areas more convenient, significantly reducing maintenance costs and resource waste. Furthermore, the introduction of adjustment modules enables precise adjustment of the insert module positions, thereby improving the adaptability of the base to sand cores of different sizes and shapes. The design of the shock-absorbing pad and anti-slip texture further enhances the stability and reliability of the base, ensuring high-quality completion of the casting process. This invention balances economy, flexibility, and practicality in its structural design, providing new ideas for the technological development of sand core mold bases. Attached Figure Description

[0021] This utility model provides a block-type composite sand core mold base, the structure of which is as follows: Figures 1 to 5As shown, the structure mainly includes a base module 1, an insert module 2, and an adjustment module 3. The base module 1, serving as the fundamental support component of the overall structure, consists of a main frame 4 and partition plates 5. The main frame 4 is a rectangular structure, and its interior is divided into several evenly distributed receiving slots 6 by horizontally and vertically arranged partition plates 5. Each receiving slot 6 has a guide groove machined into its inner wall to guide the installation direction of the insert module 2 and limit its range of movement. The thickness of the partition plates 5 is optimized to reduce material usage while ensuring the overall structural strength. The insert module 2 is embedded in the receiving slot 6 and forms a tight fit with the base module 1, while the adjustment module 3 is located on the side of the base module 1 for fine-tuning the position of the insert module 2.

[0022] The insert module 2 includes a base block 7, a positioning pin 8, and an elastic gasket 9. A positioning hole is provided at the bottom of the base block 7, through which the positioning pin 8 passes and is fixed within the receiving groove 6 of the base module 1, thereby achieving precise positioning and connection between the insert module 2 and the base module 1. The top surface of the base block 7 has anti-slip textures 15 distributed in a grid pattern to increase the friction between the base block 7 and the sand core, preventing the sand core from sliding during the molding process. The depth and spacing of the anti-slip textures 15 are calculated and optimized to balance friction performance and ease of cleaning. The elastic gasket 9 is located on the top surface of the base block 7 to provide cushioning and sealing during the sand core molding process. The base block 7 is made of high-strength, wear-resistant material, effectively extending its service life. Furthermore, the insert module 2 also includes a locking device consisting of locking bolts and a pressure plate. The pressure plate is located at the top of the insert module 2 and is fixedly connected to the base module 1 by the locking bolts. When the locking bolts are tightened, the pressure plate applies downward pressure to the insert module 2, ensuring that the insert module 2 remains stable during operation.

[0023] The adjustment module 3 includes an adjustment screw 10, a limiting block 12, a handwheel 11, and a dial 13. One end of the adjustment screw 10 passes through the side wall of the base module 1 and contacts the side of the insert module 2, while the other end is fixedly connected to the handwheel 11. By rotating the handwheel 11, the adjustment screw 10 pushes the insert module 2 along the guide groove, thereby achieving precise adjustment of the position of the insert module 2. The limiting block 12 is fixed to the middle of the adjustment screw 10 to limit the range of movement of the adjustment screw 10 and prevent over-adjustment from causing the insert module 2 to disengage from the receiving groove 6. The dial 13 is fixed to the outer surface of the handwheel 11 and is marked with precise scale lines. The operator can accurately grasp the adjustment amount of the insert module 2 by observing the values ​​on the dial 13, thus improving the adjustment accuracy.

[0024] The bottom of the base module 1 is provided with a shock-absorbing pad 14, which is made of rubber material and has good elasticity and wear resistance. The shock-absorbing pad 14 is fixed to the bottom surface of the base module 1 by adhesive bonding, and its thickness is adjusted according to the actual working conditions. The shock-absorbing pad 14 can absorb vibration during the casting process and protect the base module 1 from damage, while also helping to improve the stability of the overall structure.

[0025] In practical applications, the operation process of the modular sand core mold base of this utility model is as follows: First, place the base module 1 on the work platform, ensuring that the shock-absorbing pad 14 at its bottom is in full contact with the platform surface. Next, insert the block module 2 into the receiving groove 6 of the base module 1 through the positioning pin 8, so that the bottom of the base block 7 is tightly fitted with the inner wall of the receiving groove 6. At this time, the anti-slip texture 15 on the base block 7 faces upward, and the elastic pad 9 is located on the top surface of the base block 7. Then, by rotating the adjusting screw 10 through the handwheel 11 of the adjusting module 3, the block module 2 is pushed to move along the guide groove until the desired position is reached. During this process, the operator can observe the scale lines on the dial 13 to control the adjustment amount and ensure the accurate position of the block module 2. After the adjustment is completed, the block module 2 is fixed using a locking device. Specifically, the pressure plate is placed on top of the block module 2, and the pressure plate is fixedly connected to the base module 1 through the locking bolt. After tightening the locking bolt, the pressure plate applies downward pressure to the block module 2 to ensure its stability during operation.

[0026] During the sand core molding process, the elastic gasket 9 on the top of the base block 7 acts as a buffer and seal, preventing defects in the sand core due to uneven stress. The anti-slip texture 15 increases the friction between the base block 7 and the sand core, preventing the sand core from sliding. After the sand core molding is completed, if a piece of the insert module 2 is worn or damaged, it can simply be removed from the receiving slot 6 of the base module 1 and replaced with a new insert module 2, without having to replace the entire bottom mold base. This partial replacement method significantly reduces maintenance costs and resource waste.

[0027] Furthermore, when it is necessary to adapt to sand cores of different sizes or shapes, the position of the insert module 2 can be adjusted via the adjustment module 3. Specifically, the locking device is loosened, the handwheel 11 is rotated to drive the adjusting screw 10 to move the insert module 2, and then it is re-locked after being adjusted to the appropriate position. In this way, this invention can flexibly meet the production needs of sand cores of different specifications, improving its overall adaptability.

[0028] As can be seen from the above description, this utility model, through the coordinated operation of the base module 1, the insert module 2, and the adjustment module 3, achieves independent replacement of local areas and flexible adjustment of the overall structure. Its structural design is reasonable, the connections between components are tight, and operation is simple, effectively solving the shortcomings of traditional integral sand core mold bases in terms of maintainability, economy, and adaptability.

[0029] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0030] In actual operation in the foundry workshop, the sand core mold base is installed on the working platform of the die-casting machine. First, the base module 1 is placed stably on the workbench surface. At this time, the shock-absorbing pad 14 at the bottom of the base module 1 is in contact with the platform to ensure the stability of the entire structure. The shock-absorbing pad 14 is made of rubber material, and its internal elastic molecular structure can absorb the vibration energy generated during the casting process, preventing the vibration from being transmitted to the main frame 4 of the base module 1, thereby protecting the structural integrity of the partition plate 5 and the receiving groove 6.

[0031] Subsequently, the operators inserted the insert modules 2 one by one into the receiving slots 6 of the base module 1. During the insertion process, the positioning holes at the bottom of the base block 7 are precisely aligned with the fixing points in the receiving slots 6 via positioning pins 8. The design of the positioning pins 8 not only enables the rapid installation of the insert modules 2, but also restricts the horizontal displacement of the base block 7 through its rigid connection, ensuring that the insert modules 2 will not shift during operation. In addition, the guide grooves on the inner wall of the receiving slots 6 further guide the installation direction of the base blocks 7 and limit their range of movement, preventing positional deviations caused by external impacts.

[0032] After the initial installation of the insert module 2 is completed, the operator makes precise adjustments using the adjustment module 3. Specifically, rotating the handwheel 11 drives the adjusting screw 10 to rotate, and the adjusting screw 10 pushes the insert module 2 along the guide groove through threaded transmission. The presence of the limit block 12 effectively limits the range of movement of the adjusting screw 10, preventing the insert module 2 from dislodging from the receiving groove 6 due to over-adjustment. During this process, the operator can observe the scale lines on the dial 13 to determine the adjustment amount, ensuring that the position of each insert module 2 meets the design requirements. After all insert modules 2 have been adjusted, they are fixed in place using a locking device. Specifically, a pressure plate is placed on top of the insert module 2 and fixedly connected to the base module 1 using locking bolts. After tightening the locking bolts, the pressure plate applies downward pressure to the insert module 2, keeping it stable during operation.

[0033] During the core forming stage, the elastic gasket 9 on top of the substrate block 7 plays a crucial role. Made of flexible material, the elastic gasket 9 provides cushioning during core forming, preventing surface defects due to uneven pressure. Simultaneously, its sealing performance prevents core material from seeping into the gap between the substrate block 7 and the receiving groove 6, extending the equipment's lifespan. The anti-slip texture 15 on top of the substrate block 7 prevents the core from sliding during forming by increasing friction. The optimized mesh design of the anti-slip texture 15 ensures sufficient friction while facilitating the cleaning of residual core material.

[0034] When a component module 2 becomes worn or damaged due to prolonged use, the operator only needs to loosen the corresponding locking device, remove the damaged component module 2, and replace it with a new one. This partial replacement method significantly reduces maintenance costs and avoids the problem of needing to replace the entire traditional integral mold base due to partial damage. Furthermore, because the component module 2 is made of high-strength, wear-resistant material, its service life is significantly extended compared to traditional designs, further improving economic efficiency.

[0035] When producing sand cores of different sizes or shapes, operators can flexibly adjust the position of the insert module 2 using the adjustment module 3. Specifically, the locking device is loosened, the handwheel 11 is rotated to drive the adjusting screw 10 to move the insert module 2, and then it is re-locked after being adjusted to the appropriate position. In this way, this invention can adapt to the production needs of sand cores of various specifications, significantly improving its adaptability.

[0036] In summary, this utility model, through the coordinated operation of the base module 1, the insert module 2, and the adjustment module 3, achieves independent replacement of local areas and flexible adjustment of the overall structure. Its structural design is reasonable, the connections between components are tight, and operation is simple, effectively addressing the shortcomings of traditional integral sand core mold bases in terms of maintainability, economy, and adaptability.
