Description

Technical Field

[0001] The present application belongs to the technical field of sand core manufacturing, and in particular relates to a sand core transport pallet. Background Art

[0002] The foundry industry is developing rapidly, the degree of automation is getting higher and higher, and the less-manpowered casting is developing rapidly. The inner cavity formed in the cylinder casting is formed by sand cores. There are many types of sand cores, which are divided into two categories: main cores and auxiliary cores. The main core is composed of several large cylinder cores, and the auxiliary cores are divided into upper cover cores, water cavity channel cores, oil channel cores, water inlet channel cores, oil return channel cores, etc. There are many types of auxiliary cores, and the sizes are not uniform, and the shapes are complex. After core making, it is usually necessary to use a pallet to transport it to the core assembly station or to the dipping station.

[0003] Most common auxiliary core pallets can only accommodate four types of sand cores. If more sand cores are placed, the pallet needs to be replaced. Since the workshop has two sets of auxiliary core making centers, it can produce two sets of auxiliary core sand cores at the same time, so the auxiliary core transport pallet must meet the requirements of arranging two sets of auxiliary core sand cores at the same time. At the same time, the workshop produces many types of products, and the auxiliary core structure and size used in each product are very different. The auxiliary core pallet must meet the structural requirements of all auxiliary cores.

[0004] However, the inventors found that the existing pallet design cannot meet the needs of a workshop for the use of multiple types of sand cores, and replacing the pallet will waste time and consume a lot of manpower and material resources. Utility Model Content

[0005] The present application provides a sand core transport pallet to solve the problem of discharging multiple sand cores and meeting the structural requirements for discharging different sand cores.

[0006] The technical solution adopted in this application is:

[0007] A sand core transport pallet comprises a base plate, a first L-shaped bracket arranged at both ends of the base plate, a second L-shaped bracket arranged on the base plate, an accompanying pallet arranged on the base plate, a U-shaped bracket arranged on the base plate, a combined bracket arranged on the base plate and a cylinder arranged on the base plate; the U-shaped bracket is arranged beside the first L-shaped bracket, the accompanying pallet is arranged on the other side of the U-shaped bracket, the second L-shaped bracket is arranged beside the accompanying pallet, the cylinder is arranged beside the second L-shaped bracket, the combined bracket is arranged beside the cylinder, another second L-shaped bracket is arranged beside the combined bracket, and another first L-shaped bracket is arranged beside another second L-shaped bracket.

[0008] According to the sand core transport pallet provided in the embodiment of the present application, by setting different types of brackets (a first L-shaped bracket, a second L-shaped bracket, a U-shaped bracket and a combined bracket) and a cylinder on the bottom plate of the pallet, this design can adapt to the discharge needs of sand cores of various sizes and shapes. In particular, the design of the accompanying pallet can flexibly adjust the position according to the specific sand core size and production requirements to achieve compatibility with sand cores of different models, thereby improving the versatility and flexibility of the pallet. The layout of each component takes into account the actual shape and size of the sand core. For example, the layout beside the U-shaped bracket is conducive to the placement of long strips or special shapes of sand cores, and the setting of the accompanying pallet can quickly switch the discharge mode according to the changes in production tasks, which enables the pallet to maximize the loading of sand cores in a limited space and improves the efficiency of space utilization.

[0009] Optionally, the middle of the bottom plate is a hollow structure, and the hollow structure is provided with a first support plate and a second support plate.

[0010] By adopting the above technical solution, the hollow design can effectively reduce the overall weight of the pallet, which is crucial for automated production lines because lighter pallets can reduce the energy consumption of the robot arm or transmission system and improve handling efficiency. At the same time, the setting of the first and second support plates ensures the structural strength of the hollow structure, avoids the weakening of rigidity caused by hollowing, and ensures the stability and durability of the pallet when carrying the sand core.

[0011] Optionally, the first support plate and the second support plate are cross-connected to each other.

[0012] By adopting the above technical solution, the structural strength and stability of the hollow area in the middle of the pallet are significantly enhanced through the cross-connection design of the first support plate and the second support plate. Even when the pallet is fully loaded with heavy sand cores, it can effectively prevent the middle area from sinking or deforming, ensure the overall rigidity of the pallet during transportation, and extend its service life. The cross-connected support plate layout can more evenly disperse the weight borne by the pallet and avoid local overload, which helps to protect the pallet structure from damage, and keeps the pallet balanced during dynamic handling, reduces vibration and shaking, and protects the sand core from damage.

[0013] Optionally, the first L-shaped bracket includes a first support column and a first L-shaped frame, and the first L-shaped frame is welded to the first support column.

[0014] By adopting the above technical solution, the first L-shaped frame and the first support column are connected by welding to form a solid integral structure. This direct fixing method significantly enhances the stability and load-bearing capacity of the pallet bearing area, ensuring that the pallet is not easily deformed or damaged when placing and transporting heavy or large sand cores, thereby improving the overall work safety and reliability. The design of the first L-shaped bracket, especially the combination of its vertical part (first support column) and horizontal part (first L-shaped frame), enables the pallet to effectively support and position the sand core in a limited space, especially for those sand cores with larger volume and special shape, such as upper cover core, etc., through the reasonable layout of the first L-shaped bracket, the edge space of the pallet can be effectively utilized, thereby increasing the effective use area of ​​the pallet.

[0015] Optionally, the first L-shaped frame includes a first sand core bearing portion and a first sand core abutting portion, the first sand core abutting portion and the first support column form an angle, the angle opening direction is toward the outside of the base plate, and the first sand core bearing portion and the first sand core abutting portion form a right angle.

[0016] By adopting the above technical solution, the right-angle design of the first sand core bearing part and the first sand core abutting part provides a stable support and accurate positioning for the sand core, especially for sand cores with long or large shapes such as upper cover cores. Such a design can ensure that the sand core maintains the correct posture during transportation, reduce the tilting or sliding caused by movement, and ensure the integrity of the sand core. The setting of the angle opening direction toward the outside of the bottom plate facilitates the placement of the sand core, thereby speeding up the operation speed and improving the efficiency of the automated production line. The welding connection between the first L-shaped frame and the first support column, plus the reasonably designed angle structure, jointly improves the structural strength and stability of the entire pallet, especially when carrying heavy objects, it can effectively disperse stress, reduce structural damage caused by excessive local force, and extend the service life of the pallet. The angle design of the first sand core abutting part makes the arrangement of the sand core on the pallet more orderly. Through the angle and right-angle design, sand cores of different shapes and sizes can be reasonably arranged without increasing the overall size of the pallet, maximizing the loading capacity of the pallet, thereby improving the space utilization efficiency of the production process and reducing logistics and storage costs.

[0017] Optionally, the second L-shaped bracket includes a second support column and a second L-shaped frame, and the second support column and the second L-shaped frame are welded to each other.

[0018] By adopting the above technical solution, the second L-shaped frame and the second support column form a solid integrated structure through welding connection. This direct fixed connection method significantly enhances the load-bearing capacity and overall stability of the pallet, especially when it needs to bear sand cores of different weights and shapes. It can effectively prevent structural deformation or breakage, and ensure the reliability of the pallet under high-intensity use. The layout of the second L-shaped bracket, in conjunction with the first L-shaped bracket and other structures, jointly realizes the efficient use of the pallet space. The L-shaped design enables the bracket to provide sufficient support force without hindering the flexible layout of the internal space of the pallet, providing more possibilities for the discharge of sand cores of different sizes and shapes, and meeting the needs of switching between multiple types of sand cores in the workshop.

[0019] Optionally, the second L-shaped frame includes a second sand core bearing portion and a second sand core abutting portion, the second sand core abutting portion and the second supporting column form an angle, and the second sand core bearing portion and the second sand core abutting portion form a right angle.

[0020] By adopting the above technical solution, the right-angle design of the second sand core bearing part and the second sand core abutting part provides a stable support platform for the sand core, ensuring the stable placement of the sand core on the pallet, especially for sand cores of various shapes and sizes. This design can effectively prevent the sand core from sliding or tipping over during transportation, ensuring the integrity of the sand core and the quality of the final casting. The second L-shaped frame structure connected by welding, combined with a specific angle design, can effectively disperse the load borne by the pallet, reduce stress concentration, thereby enhancing the overall stability and load-bearing capacity of the pallet, and ensuring that the pallet structure is still strong and reliable when fully loaded with a variety of sand cores. The ingenious combination of right angles and angles enables the pallet to arrange the discharge layout of the sand core more reasonably within a limited space, which not only meets the simultaneous transportation needs of a variety of sand cores, but also ensures the compactness and lightweight of the pallet structure, improves space utilization efficiency, and meets the requirements of modern production for high efficiency and low energy consumption.

[0021] Optionally, the combined bracket includes the accompanying tray and the U-shaped bracket, and the U-shaped bracket is arranged on the accompanying tray.

[0022] By adopting the above technical solutions, the introduction of the accompanying pallet allows the pallet to be flexibly adjusted according to production needs to adapt to sand cores of different sizes and shapes. In particular, for sand cores with special structures such as cylinder cores, the accompanying pallet can be adjusted according to the shape, ensuring the stability and safety of the sand cores during transportation. The configuration of the U-shaped bracket further enhances the support and fixation capabilities of specific sand cores. The combination of the two enhances the versatility of the pallet and can meet the rapid switching of multiple types of sand cores. The layout design of the combined bracket fully considers the reasonable allocation of the internal space of the pallet. The U-shaped bracket is placed on the accompanying pallet, which not only provides a special support structure for sand cores of specific shapes, but also effectively utilizes the vertical space of the pallet, avoids space waste, and increases the loading capacity of sand cores on a unit pallet, thereby improving production efficiency and logistics turnover speed.

[0023] Optionally, the accompanying tray includes a third supporting column and a carrying plate.

[0024] By adopting the above technical solution, the addition of the third support column provides an additional vertical support point for the accompanying pallet, effectively dispersing the weight pressure of the upper sand core and reducing the risk of bending and deformation of the load-bearing plate. Especially when carrying heavier or large-sized sand cores, it can ensure the stability of the overall structure of the pallet and improve the vibration resistance and durability of the pallet under dynamic working conditions. The design of the load-bearing plate allows for flexible adjustment according to the specific size and shape of the sand core. By adjusting the position of the load-bearing plate or designing load-bearing plates of different sizes, it can meet the transportation needs of more types of sand cores. This design not only maximizes the use of the available space on the pallet, but also facilitates the rapid switching of multiple types of sand cores in the workshop, reduces the frequency of pallet replacement, and saves time and labor costs.

[0025] Optionally, the U-shaped bracket includes a U-shaped frame and a fourth supporting column.

[0026] By adopting the above technical solution, the design of the U-shaped frame, through its unique opening structure, provides a stable support platform for sand cores of specific shapes, especially for long or special-shaped sand cores. The U-shaped frame can fit closely with the contour of the sand core, effectively preventing the sand core from rolling or shifting during transportation, and ensuring the stable storage of the sand core. The addition of the fourth support column further enhances the vertical support force of the U-shaped frame, improves the overall load-bearing performance, and ensures the structural stability of the pallet when fully loaded. The design of the U-shaped bracket takes into account the efficient use of space. The opening orientation and position layout of the U-shaped frame can adapt to the discharge requirements of sand cores of different sizes, reducing the waste of space inside the pallet. The clever integration of the fourth support column not only supports the U-shaped frame, but also avoids the encroachment of other parts of the pallet space, so that the pallet can maximize the loading capacity of sand cores in a limited space, thereby improving production efficiency.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0028] By setting different types of brackets (first L-shaped bracket, second L-shaped bracket, U-shaped bracket and combined bracket) and cylinders on the bottom plate of the pallet, this design can adapt to the discharge needs of sand cores of various sizes and shapes. In particular, the design of the accompanying pallet can flexibly adjust the position according to the specific sand core size and production requirements to achieve compatibility with sand cores of different models, thereby improving the versatility and flexibility of the pallet. The layout of each component takes into account the actual shape and size of the sand core. For example, the layout of the U-shaped bracket is conducive to the placement of long or special-shaped sand cores, and the setting of the accompanying pallet can quickly switch the discharge mode according to the changes in production tasks. This allows the pallet to maximize the loading of sand cores in a limited space and improves space utilization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Reference Figure 1 A sand core transport pallet comprises a base plate, a first L-shaped bracket arranged at both ends of the base plate, a second L-shaped bracket arranged on the base plate, an accompanying pallet arranged on the base plate, a U-shaped bracket arranged on the base plate, a combined bracket 12 arranged on the base plate and a cylinder 7 arranged on the base plate; the U-shaped bracket is arranged beside the first L-shaped bracket, an accompanying pallet is arranged on the other side of the U-shaped bracket, a second L-shaped bracket is arranged beside the accompanying pallet, a cylinder 7 is arranged beside the second L-shaped bracket, a combined bracket 12 is arranged beside the cylinder 7, another second L-shaped bracket is arranged beside the combined bracket 12, and another first L-shaped bracket is arranged beside the other second L-shaped bracket.

[0039] Specifically, the first L-shaped bracket is used to carry the upper cover core, the second L-shaped bracket is used to carry the tappet core, the accompanying tray is used to carry the water cavity channel core, the cylinder 7 is used to carry the water inlet channel core, and the U-shaped bracket and the combined bracket 12 are used to carry the cylinder core or the upper cover core. The first L-shaped bracket, the second L-shaped bracket, the accompanying tray, the cylinder 7, the U-shaped bracket and the combined bracket 12 are all connected to the second support plate of the bottom plate hollow structure by welding.

[0040] For example, in this embodiment, two groups of first L-shaped brackets can be provided on the bottom plate, which are respectively provided on both sides of the bottom plate, and each group is provided with three first L-shaped brackets, and the two groups of first L-shaped brackets are used to carry two upper cover cores. Two groups of second L-shaped brackets are also provided on the bottom plate, and each group is provided with four second L-shaped brackets, which are used to carry two push rod cores. Three U-shaped brackets are also provided on the bottom plate, which are used to carry the upper cover core or the cylinder head core. Three cylinders are also provided on the bottom plate, which are used to carry the water inlet channel core. A casual tray is also provided on the floor, which is used to carry the water cavity channel core, and the third support column of the accompanying tray is provided with three. A combined bracket is also provided on the bottom plate, which is used to carry the upper cover core or the cylinder head core, and there are two U-shaped frames on the combined bracket, and three fourth support columns are provided.

[0041] The present application does not specifically limit the size of the base plate. Preferably, the base plate is 1400 mm long and 1300 mm wide.

[0042] Furthermore, anti-skid materials with adaptive friction can be used on the surface of the pallet and key support contact points to ensure the stability of the sand core during transportation and reduce displacement caused by vibration. At the same time, special surface treatment is performed on the pallet, such as high temperature resistant and anti-corrosion coating, to extend the service life and reduce pollution to the sand core. Pneumatic or hydraulic lifting mechanisms can also be integrated at the bottom of the pallet so that the height of the pallet can be automatically adjusted according to the height requirements of different links of the production line, such as automatically raising it when loading and unloading sand cores to adapt to the robot grabbing height, or lowering it during transportation to reduce the center of gravity and improve stability.

[0043] According to the sand core transport pallet provided in the embodiment of the present application, by arranging different types of brackets (a first L-shaped bracket, a second L-shaped bracket, a U-shaped bracket and a combined bracket 12), and a cylinder 7 on the bottom plate of the pallet, this design can adapt to the discharge requirements of sand cores of various sizes and shapes. In particular, the design of the accompanying pallet can flexibly adjust the position according to the specific sand core size and production requirements to achieve compatibility with sand cores of different models, thereby improving the versatility and flexibility of the pallet. The layout of each component takes into account the actual shape and size of the sand core. For example, the layout beside the U-shaped bracket is conducive to the placement of long strips or special shapes of sand cores, and the setting of the accompanying pallet can quickly switch the discharge mode according to the changes in production tasks, which enables the pallet to maximize the loading of sand cores in a limited space and improves the efficiency of space utilization.

[0044] In a preferred embodiment, the middle of the bottom plate is a hollow structure, and the hollow structure is provided with a first support plate and a second support plate.

[0045] Specifically, the second support plate is arranged above the first support plate, the second support plate is used to connect the bracket above the support, and the first support plate is used to enhance the stability of the overall frame.

[0046] The present application does not specifically limit the number of the first support plates and the second support plates. Preferably, the number of the first support plates is 3 and the number of the second support plates is 12.

[0047] Furthermore, the support plate can be designed as a modular component, and support modules of different specifications can be quickly disassembled and replaced to meet the needs of sand cores of different sizes and shapes. Standardized interfaces are used between modules to facilitate rapid on-site adjustments and reduce production preparation time. Dynamic balancing compensation devices, such as pneumatic springs or hydraulic systems, can also be integrated under the bottom plate. When the pallet is unevenly loaded, the system automatically adjusts to ensure the stability of the pallet during transportation and reduce the risk of sand core damage due to vibration.

[0048] In a preferred embodiment, the first support plate and the second support plate are cross-connected to each other.

[0049] Specifically, the first support plate can be connected by welding or bolts below the second support plate. The present application does not specifically limit the connection method between the first support plate and the second support plate.

[0050] The cross-connected design of the first and second support plates significantly enhances the structural strength and stability of the hollow structure in the middle of the pallet. Even when the pallet is fully loaded with heavy sand cores, it can effectively prevent the middle area from sinking or deforming, ensuring the overall rigidity of the pallet during transportation and extending its service life. The cross-connected support plate layout can more evenly distribute the weight borne by the pallet and avoid local overload, which helps protect the pallet structure from damage and keeps the pallet balanced during dynamic handling, reducing vibration and shaking, and protecting the sand cores from damage.

[0051] In a preferred embodiment, the first L-shaped bracket includes a first support column 3 and a first L-shaped frame, and the first L-shaped frame is connected to the first support column 3 by welding.

[0052] Specifically, in this embodiment, two first L-shaped brackets are provided, the opening directions of the two first L-shaped brackets are opposite, and the two first L-shaped brackets are respectively provided at two ends of the bottom plate.

[0053] Furthermore, the first L-shaped bracket is designed as a detachable module, which is connected to the base plate through a standardized interface instead of direct welding. In this way, under different production requirements, L-shaped bracket modules of different heights and widths can be quickly replaced according to the size and shape of the sand core, thereby improving the adaptability and flexibility of the pallet. An integrated buffer pad or shock-absorbing device is designed at the connection between the first L-shaped bracket and the base plate to absorb vibration and impact during transportation, protect the sand core from damage, and improve the yield rate of the sand core.

[0054] Through welding connection, the first L-shaped frame and the first support column 3 form a solid overall structure. This direct fixing method significantly enhances the stability and load-bearing capacity of the pallet's bearing area, ensuring that the pallet is not easily deformed or damaged when placing and transporting heavy or large sand cores, thereby improving the overall work safety and reliability. The design of the first L-shaped bracket, especially the combination of its vertical part (first support column 3) and horizontal part (first L-shaped frame), enables the pallet to effectively support and position the sand core in a limited space, especially for those sand cores with larger volume and special shape, such as upper cover cores, etc. Through the reasonable layout of the first L-shaped bracket, the edge space of the pallet can be effectively utilized to increase the effective use area of ​​the pallet.

[0055] In a preferred embodiment, the first L-shaped frame includes a first sand core bearing portion 2 and a first sand core abutting portion 1, and the first sand core abutting portion 1 has an angle with the first support column 3, the opening direction of the angle is toward the outside of the base plate, and the first sand core bearing portion 2 is at a right angle to the first sand core abutting portion 1.

[0056] The present application does not specifically limit the connection method between the first support column 3 and the first sand core abutment portion 1. Preferably, a welding connection method is adopted. An adjustable connection structure can also be designed at the connection between the first sand core abutment portion 1 and the first support column 3, allowing the user to adjust the angle according to the actual size and shape of the sand core, thereby achieving a wider range of sand core adaptability and increasing the versatility of the tray.

[0057] Furthermore, the first sand core abutment portion 1 is wrapped with an elastic flexible material to adapt to sand cores of different hardness and shapes, thereby reducing damage to the sand cores during transportation, while maintaining a good abutment effect and increasing the stability and protection of the sand cores.

[0058] The right-angle design of the first sand core bearing part 2 and the first sand core abutting part 1 provides a stable support and accurate positioning for the sand core, especially for sand cores with a long or large shape such as the upper cover core. Such a design can ensure that the sand core maintains the correct posture during transportation, reduce the tilting or sliding caused by movement, and ensure the integrity of the sand core. The setting of the angle opening direction toward the outside of the bottom plate facilitates the placement of the sand core, thereby speeding up the operation speed and improving the efficiency of the automated production line. The welding connection between the first L-shaped frame and the first support column 3, plus the reasonably designed angle structure, jointly improves the structural strength and stability of the entire pallet, especially when carrying heavy objects, it can effectively disperse stress, reduce structural damage caused by excessive local force, and extend the service life of the pallet. The angle design of the first sand core abutting part 1 makes the arrangement of the sand core on the pallet more orderly. Through the angle and right-angle design, sand cores of different shapes and sizes can be reasonably arranged without increasing the overall size of the pallet, maximizing the loading capacity of the pallet, thereby improving the space utilization efficiency of the production process and reducing logistics and storage costs.

[0059] In a preferred embodiment, the second L-shaped bracket includes a second support column 6 and a second L-shaped frame, and the second support column 6 and the second L-shaped frame are welded.

[0060] Specifically, since two second L-shaped brackets are provided in this embodiment, the opening directions of the two second L-shaped brackets are consistent.

[0061] Furthermore, the second support column 6 and the second L-shaped frame can also be designed with an adjustable connection structure, that is, a threaded connection or a quick lock structure is adopted, so that the height of the support column and the angle of the L-shaped frame can be fine-tuned according to the size and weight of the sand core, thereby improving the adaptability and flexibility of the pallet.

[0062] Through welding connection, the second L-shaped frame and the second support column 6 form a solid integrated structure. This direct fixed connection method significantly enhances the load-bearing capacity and overall stability of the pallet, especially when it needs to bear sand cores of different weights and shapes. It can effectively prevent structural deformation or breakage, and ensure the reliability of the pallet under high-intensity use. The layout of the second L-shaped bracket, in conjunction with the first L-shaped bracket and other structures, jointly realizes the efficient use of the pallet space. The L-shaped design enables the bracket to provide sufficient support force without hindering the flexible layout of the internal space of the pallet, providing more possibilities for the arrangement of sand cores of different sizes and shapes, and meeting the needs of switching between multiple types of sand cores in the workshop.

[0063] In a preferred embodiment, the second L-shaped frame includes a second sand core bearing portion 5 and a second sand core abutting portion 4 , the second sand core abutting portion 4 and the second supporting column 6 form an angle, and the second sand core bearing portion 5 and the second sand core abutting portion 4 are at a right angle.

[0064] The present application does not specifically limit the connection method between the second sand core abutment portion 4 and the second support column 6. Preferably, welding connection is adopted. The angle between the second sand core abutment portion 4 and the second support column 6 can also be designed as an adjustable structure. Through a threaded knob or a hydraulic system, the operator can adjust the angle on site according to the size and shape requirements of different sand cores to achieve better support effect and stability.

[0065] The right-angle design of the second sand core bearing portion 5 and the second sand core abutting portion 4 provides a stable support platform for the sand core, ensuring that the sand core is firmly placed on the pallet. Especially for sand cores of various shapes and sizes, this design can effectively prevent the sand core from sliding or tipping over during transportation, ensuring the integrity of the sand core and the quality of the final casting. The second L-shaped frame structure connected by welding, combined with a specific angle design, can effectively disperse the load borne by the pallet, reduce stress concentration, thereby enhancing the overall stability and load-bearing capacity of the pallet, and ensuring that the pallet structure remains strong and reliable when fully loaded with a variety of sand cores. The ingenious combination of right angles and angles enables the pallet to more reasonably arrange the discharge layout of the sand cores in a limited space, which not only meets the simultaneous transportation needs of a variety of sand cores, but also ensures the compactness and lightweight of the pallet structure, improves space utilization efficiency, and meets the requirements of modern production for high efficiency and low energy consumption.

[0066] In a preferred embodiment, the combined bracket 12 includes a traveling tray and a U-shaped bracket, and the U-shaped bracket is arranged on the traveling tray.

[0067] The present application does not make any specific limitation on the connection method between the portable pallet and the U-shaped bracket. Preferably, a bolt-fixed connection method is adopted. The portable pallet and the U-shaped bracket can also be designed as threaded holes, quick-release pins, snap buckles and other structures. Through such standardized interfaces and quick locking mechanisms, pallets and U-shaped brackets of different specifications can be quickly replaced according to different sand core size and shape requirements, thereby improving the flexibility and adaptability of the pallet system.

[0068] The introduction of the accompanying pallet allows the pallet to be flexibly adjusted according to production needs to accommodate sand cores of different sizes and shapes. In particular, for sand cores with special structures such as cylinder cores, the accompanying pallet can be adjusted according to the shape, ensuring the stability and safety of the sand cores during transportation. The configuration of the U-shaped bracket further enhances the support and fixation capabilities for specific sand cores. The combination of the two enhances the versatility of the pallet and can meet the rapid switching of multiple types of sand cores. The layout design of the combined bracket 12 fully considers the reasonable allocation of the internal space of the pallet. The U-shaped bracket is placed on the accompanying pallet, which not only provides a special support structure for sand cores of specific shapes, but also effectively utilizes the vertical space of the pallet, avoids waste of space, and increases the loading capacity of sand cores on a unit pallet, thereby improving production efficiency and logistics turnover speed.

[0069] In a preferred embodiment, the accompanying tray includes a third supporting column 9 and a carrying plate 8 .

[0070] Specifically, the third support column 9 is connected to the second support plate of the bottom plate. A plurality of third support plates may be provided to support the bearing plate 8, and the bearing plate 8 is used to bear the sand core.

[0071] The addition of the third support column 9 provides an additional vertical support point for the accompanying pallet, effectively dispersing the weight pressure of the upper sand core and reducing the risk of bending and deformation of the load-bearing plate 8, especially when carrying heavier or large-sized sand cores. It can ensure the stability of the overall structure of the pallet and improve the vibration resistance and durability of the pallet under dynamic working conditions. The design of the load-bearing plate 8 allows for flexible adjustment according to the specific size and shape of the sand core. By adjusting the position of the load-bearing plate 8 or designing load-bearing plates 8 of different sizes, it can meet the transportation needs of more types of sand cores. This design not only maximizes the use of the available space on the pallet, but also facilitates the rapid switching of multiple types of sand cores in the workshop, reduces the frequency of pallet replacement, and saves time and labor costs.

[0072] In a preferred embodiment, the U-shaped bracket includes a U-shaped frame 10 and a fourth supporting column 11 .

[0073] Specifically, the fourth support column 11 is connected to the second support plate of the bottom plate, and a plurality of fourth support columns 11 may be provided to support the U-shaped frame 10, and the U-shaped frame 10 is used to carry the sand core.

[0074] The design of the U-shaped frame 10, through its unique opening structure, provides a stable support platform for sand cores of specific shapes, especially for long or special-shaped sand cores, the U-shaped frame 10 can fit closely with the contour of the sand core, effectively preventing the sand core from rolling or shifting during transportation, and ensuring the stable storage of the sand core. The addition of the fourth support column 11 further enhances the vertical support force of the U-shaped frame 10, improves the overall load-bearing performance, and ensures the structural stability of the pallet when fully loaded. The design of the U-shaped bracket takes into account the efficient use of space. The opening orientation and position layout of the U-shaped frame 10 can adapt to the discharge requirements of sand cores of different sizes, reducing the waste of space inside the pallet. The clever integration of the fourth support column 11 not only supports the U-shaped frame 10, but also avoids the occupation of other parts of the pallet space, so that the pallet can maximize the loading capacity of sand cores in a limited space, thereby improving production efficiency.

[0075] The sand core transport pallet provided in the embodiment of the present application can transport the sand cores shown in Table 1, a total of 20 types of sand cores. There are six ways to use the pallet: method 1: place 1 set of 4 WP12 body auxiliary cores; method 2: place 1 set of 3 WP10 body auxiliary cores; method 4: place 2 sets of 4 auxiliary cores of one of the WP11H, WP13H, WP14T vermicular iron, and WP14T gray iron bodies. For a certain body, 2 types of sand cores are 2 each; method 5: 2 sets of 2 WP14H body water jacket cores or WP15T body water jacket cores can be placed, possibly one WP14H and one WP15T body; method 6: place 1 set of WP9H / 10H / 10.5H body auxiliary cores (3 in total), plus 1 set of 2 sand cores of one of the WP11H, WP13H, WP14T vermicular iron, and WP14T gray iron bodies. Or 1 set of auxiliary cores for WP9H / 10H / 10.5H (3 in total), plus 1 sand core for either WP14H or WP15T.
