Description

Technical Field

[0001] This application relates to the demolding of cabin molds, and more particularly to a modular disassembly device and method for the internal structure of a cabin. Background Technology

[0002] In large-scale casting production, for cylindrical cabin castings with complex shapes and non-rotational internal structures, the inner wall often needs to form annular or locally raised structures to meet requirements such as strength, functional installation, or structural connection. These raised structures are typically formed during the casting process by inner mold inserts evenly distributed around the outer circumference of the inner mold, which work in conjunction with the outer mold.

[0003] When the inner wall of the hull casting is smooth, the separation of the casting from the inner mold can be easily accomplished along the casting axis (i.e., straight up and down). However, when there are protrusions on the inner wall, the mold insert forms an interlocking relationship with the casting after it is formed, making it impossible to directly demold along the casting axis. It is necessary to first separate the mold insert from the inner mold, and then separate the mold insert from the casting in the horizontal direction (i.e., perpendicular to the casting axis).

[0004] Due to the large size and weight of the cabin castings, and their casting in a high-temperature aluminum alloy state, the demolding process requires not only significant separation force but also consideration of the casting's structural strength and machining accuracy. Manual disassembly is inefficient and carries high safety risks. Therefore, in existing production processes, specialized auxiliary equipment is typically needed to assist in separating the mold inserts from the cabin castings. Some equipment is purely manual, resulting in high labor intensity and low efficiency; others, while incorporating hydraulic or other power units, lack structural specificity, making it difficult to adapt to the complex non-rotational structure inside the cabin castings, and their reliability is insufficient in the high-temperature, large-component working environment.

[0005] Therefore, there is an urgent need to provide a modular quick-release device with a reasonable structure, strong adaptability, and the ability to efficiently and safely separate the inner mold insert from the cabin casting under semi-automatic conditions, so as to improve casting production efficiency, reduce manual labor intensity, and ensure casting quality. Summary of the Invention

[0006] The purpose of this application is to provide a modular quick-release device with a reasonable structure, strong adaptability, and the ability to efficiently and safely separate the inner mold insert from the cabin casting under semi-automatic conditions, so as to improve casting production efficiency, reduce manual labor intensity, and ensure casting quality.

[0007] According to one aspect of this application, a modular disassembly device for the internal structure of a cabin is provided for removing multiple internal mold inserts within a cabin casting, the quick-release device comprising: A mechanical crane transfers the cabin casting from the pallet to the positioning seat; The extraction and unloading mechanism is inserted into the cabin casting by a mechanical crane and is limited by the positioning seat in the vertical axis of the cabin casting. During the insertion process, it completes the guide rail connection with at least one inner mold insert along the axis. The unloading mechanism pulls out the inner mold insert along the vertical axis and connects it to the inner mold insert along the axis by screws; after the mechanical crane lifts the unloading mechanism and the inner mold insert connected to it along the axis to unload and separate them, the unloading mechanism is returned to the cabin casting, and the remaining inner mold inserts are removed in sequence.

[0008] In at least one embodiment of this application, a limiting protrusion is formed on the inner surface of the cabin casting, and a limiting groove corresponding to the limiting protrusion is formed on the outer surface of the inner mold insert; a limiting through hole is formed on the limiting protrusion, penetrating the cabin casting along the vertical axis, and a limiting post extending into the limiting through hole is formed in the limiting groove. The inner surface of the inner mold insert is formed with a limiting groove extending along the axial direction, and when viewed along the axial direction, the positions of the limiting groove and the limiting post correspond to the positions of the limiting groove. The extraction and unloading mechanism includes at least two limiting sliders. Before the extraction and unloading mechanism is inserted into the cabin casting, when viewed axially, the limiting sliders are aligned with the limiting slots. During the insertion of the extraction and unloading mechanism, the limiting sliders are inserted into the limiting slots axially, and when viewed vertically, the limiting post is located between the two limiting sliders. When the unloading mechanism pulls the inner mold insert along the vertical axis, the limiting groove retracts from the limiting protrusion, and the limiting post retracts from the limiting through hole, so as to separate the inner mold insert from the cabin casting in the axial direction.

[0009] In at least one embodiment of this application, the limiting groove extends axially downward from the upper end of the inner mold insert, and a first screw hole is formed at the upper end of the inner mold insert. When viewed axially, the first screw hole is disposed adjacent to the limiting groove. The extraction and unloading mechanism includes: a support body that is inserted into the hull casting along the axial direction, and a rotating connector with one end rotatably connected to the support body and the other end connected to the first screw hole by screw engagement, wherein the rotating connector has a U-shaped hole that extends through the axial direction. Before the extraction mechanism is inserted into the cabin casting, the limiting slider is aligned with the limiting slot of the inner mold insert. Observing along the axial direction, the rotating connector rotates to a position offset from the inner mold insert. When the unloading mechanism is inserted into the cabin casting and the inner mold insert is pulled out to separate it from the cabin casting in the vertical axis, the rotating connector rotates to a position corresponding to the inner mold insert, and rotates to a position where the position of the U-shaped hole corresponds to the position of the first screw hole. Before lifting the extraction mechanism and its connected inner mold insert along the axial direction, screws are first inserted into the U-shaped hole and the first screw hole in sequence to connect the rotating connector and the inner mold insert.

[0010] In at least one embodiment of this application, The unloading mechanism further includes: a hydraulic cylinder corresponding to the limiting slider, wherein the sliding guide surface of the limiting slider is arranged axially, and the limiting slider and the hydraulic cylinder are arranged opposite to each other on opposite sides of the support body along the vertical axis; The support body extends axially, and a mounting groove is formed on one side of the support body. The hydraulic cylinder is disposed in the mounting groove. The mounting groove extends recessed from one side of the support body to the other side. A push rod hole extending vertically through the mounting groove to the other side is formed. The limiting slider is disposed on the other side. The push-pull rod of the hydraulic cylinder extends through the push rod hole to the other side of the support body and is connected to the limiting slider vertically. When the limiting slider is inserted into the limiting slot, the position of the limiting slider in the vertical axis is recorded as the first position. After the limiting slider causes the inner mold insert to separate from the cabin casting in the vertical axis, the position of the limiting slider in the vertical axis is recorded as the second position. The hydraulic cylinder outputs power to the push-pull rod, and the push-pull rod pulls the limiting slider from the first position to the second position, or the push-pull rod pushes the limiting slider from the second position to the first position.

[0011] In at least one embodiment of this application, The limiting slider includes: a connecting part connected to the push-pull rod, and a sliding part integrally formed with the connecting part and slidably connected with the limiting slot, wherein the sliding guide surface is formed on the side of the sliding part facing the limiting slot; Viewed along the axial direction, the width of the sliding part on the side away from the connecting part is greater than the width of the sliding part on the side closer to the connecting part. The side with the larger width is called the outer side, and the side with the smaller width is called the inner side. The sliding part forms an abutment surface that gradually converges from the outer side to the inner side. When the unloading mechanism pulls the inner mold insert along the vertical axis, the abutment surface abuts against the limiting groove to pull the inner mold insert apart from the cabin casting.

[0012] In at least one embodiment of this application, The support body includes: a limiting support that forms a limit with the positioning seat in the axial direction of the vertical cabin casting, and an installation support that extends upward along the axial direction from the limiting support. The installation groove is formed on the installation support. When viewed along the axial direction, the limiting support is circular. The two sides of the installation support are recessed towards the center to form two opposing installation surfaces. The installation groove is formed on one of the installation surfaces, and the push rod hole extends through to the other installation surface. The positioning seat includes: a first positioning step that supports the external platform, a second positioning step that extends axially upward from the first positioning step, and a central limiting hole that passes through the first positioning step and the second positioning step. The limiting support is inserted into the central limiting hole and fits against it to form a limit in the axial direction of the vertical cabin casting. A supporting ramp is formed between the second positioning step and the first positioning step. When the cabin casting is transferred from the pallet to the positioning seat by a mechanical crane, the inner wall of the cabin casting cooperates with the supporting ramp to form a support.

[0013] In at least one embodiment of this application, the mechanical crane includes: The column is fixed to the external platform; The swing arm is rotatably connected to the column; The suspension rope is connected at one end to the swing arm and hangs naturally at the other end. A threaded connector is fixed to the other end of the lifting rope. The top of the mounting support is provided with a threaded lifting hole. The threaded connector is screwed into the threaded lifting hole to connect the mechanical crane and the unloading mechanism. The rotating connector is rotatably connected between the threaded connector and the top of the limiting support.

[0014] In at least one embodiment of this application, the number of limiting sliders is four, and they are arranged in pairs on two sides opposite the support body, so as to remove the two inner mold inserts at the same time.

[0015] In at least one embodiment of this application, the number of limiting sliders is multiple, and they are respectively disposed on multiple sides of the support body, so as to remove multiple inner mold inserts at the same time.

[0016] According to one aspect of this application, a modular disassembly method for the internal structure of a cabin is provided, for removing multiple internal mold inserts within a cabin casting, the method comprising the steps of: The mechanical crane transfers the cabin casting from the pallet to the positioning seat; The extraction and unloading mechanism is inserted into the cabin casting by a mechanical crane and forms a limit with the positioning seat in the vertical axis of the cabin casting. During the insertion process, it completes the guide rail connection with at least one inner mold insert along the axis. The extraction and unloading mechanism pulls out the inner mold insert along the vertical axis and connects it to the insert along the axial direction by screws. After the mechanical crane lifts the unloading mechanism and its connected inner mold inserts along the axial direction to unload and separate them, the unloading mechanism is returned to the cabin casting, and the remaining inner mold inserts are removed in sequence.

[0017] This application has the following beneficial effects: Significant improvements were achieved through the coordinated design of the mechanical crane, the extraction and unloading mechanism, and the positioning seat: During insertion, the extraction and unloading mechanism completes the axial guide rail connection with the inner mold insert and pulls the inner mold insert along the axial direction of the vertical cabin casting. It is specifically adapted to the complex non-rotational structure with interlocking relationships formed by the inner wall protrusion, solving the problem of insufficient targeting of the existing equipment structure; The mechanical crane undertakes heavy-load operations such as cabin transfer and inner mold insert hoisting, while the extraction and unloading mechanism achieves mechanized separation, replacing manual operation, greatly reducing labor intensity, reducing the risk of personnel exposure in high-temperature environments, and improving operational safety and efficiency; At the same time, the mechanical crane can return the extraction and unloading mechanism to the cabin to remove the remaining inner mold inserts in sequence, forming a continuous operation process to meet the removal needs of multiple inner mold inserts. The limiting design of the extraction and unloading mechanism and the positioning seat in the vertical axis provides stable support for high separation force operations, ensuring reliability under high-temperature conditions. Ultimately, it achieves efficient, safe, and stable removal of multiple inner mold inserts in the cabin casting, significantly improving the automation level and production efficiency of casting production.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Example 1 Please refer to Figure 1 - Figure 14 One embodiment of this application provides a modular disassembly device 100 for the internal structure of a cabin, used to remove multiple inner mold inserts 20 inside the cabin casting 10. The quick disassembly device includes a mechanical crane 30 and a removal mechanism 40.

[0036] The mechanical crane 30 transfers the cabin casting 10 from the pallet 70 to the positioning seat 50. The unloading mechanism 40 is inserted into the cabin casting 10 by the mechanical crane 30 and forms a limit with the positioning seat 50 in the axial direction of the cabin casting 10. During the insertion process, it completes a guide rail connection with at least one inner mold insert 20 along the axial direction.

[0037] Specifically, the unloading mechanism 40 pulls out the inner mold insert 20 along the vertical axis and connects it to the inner mold insert 20 along the axis by screws 45; after the mechanical crane 30 lifts the unloading mechanism 40 and the inner mold insert 20 connected to it along the axis to unload and separate them, the unloading mechanism 40 is returned to the cabin casting 10, and the remaining inner mold inserts 20 are removed in sequence.

[0038] Specifically, the inner mold insert 20 is usually composed of multiple inserts evenly distributed along the inner circumferential surface of the cabin casting 10, which together form an annular cavity.

[0039] The mechanical crane 30 is responsible for handling and axial lifting, and undertakes the transfer operation of the cabin casting 10. It realizes the movement of the cabin casting 10 from the pallet 70 placed after casting to the positioning seat 50, thereby replacing the dangerous operations of manually handling the cabin, inner mold insert 20 and entering the interior of the high-temperature casting. It realizes the mechanization and continuous operation of cabin transfer, equipment positioning and insert removal, and significantly speeds up the overall demolding speed.

[0040] The extraction and unloading mechanism 40 is directly responsible for performing the key action of pulling the inner mold insert 20 out of its engaged state with the casting. Axial direction refers to the direction along the axis of the cabin casting 10. The extraction and unloading mechanism 40 and the inner mold insert 20 are precisely connected axially through a preset guide rail.

[0041] Because the inner wall protrusion of the cabin casting 10 is engaged with the inner mold insert 20, it is impossible to directly demold along the axial direction of the cabin casting 10. Therefore, the extraction mechanism 40 pulls the inner mold insert 20 along the vertical axis to directly release the engagement. The screw of the extraction mechanism 40 and the screw hole of the inner mold insert 20 cooperate to strengthen the connection between the extraction mechanism 40 and the insert, ensuring that the inner mold insert 20 moves stably with the extraction mechanism 40 during the separation process, and avoiding falling off and damaging the casting or insert.

[0042] After the inner mold insert 20 separates from the cabin casting 10, the mechanical crane 30 lifts the unloading mechanism 40 and the inner mold insert 20 axially to the unloading area, completing one unloading of the inner mold insert 20. Then, the mechanical crane 30 carries the unloading mechanism 40 back to the cabin, repeating the docking and pulling process until all inner mold inserts 20 are removed. This forms a continuous operation process, meeting the removal needs of multiple inner mold inserts 20 and solving the inefficiency of manual disassembly. The cyclical operation of the mechanical crane 30 improves automation, reduces manual intervention, further reduces the risk of personnel exposure in high-temperature environments, and improves overall casting production efficiency.

[0043] In one specific embodiment, a limiting protrusion 12 is formed on the inner surface 11 of the cabin casting, and a limiting groove 23 corresponding to the limiting protrusion 12 is formed on the outer surface 21 of the inner mold insert 20; a limiting through hole 13 is formed on the limiting protrusion 12, penetrating the cabin casting 10 along the vertical axis, and a limiting post 24 extending into the limiting through hole 13 is formed in the limiting groove 23. The inner surface 22 of the inner mold insert is formed with a limiting groove 25 extending along the axial direction, and when viewed along the axial direction, the positions of the limiting groove 23 and the limiting post 24 correspond to the positions of the limiting groove 25. The extraction and unloading mechanism 40 includes at least two limiting sliders 41. Before the extraction and unloading mechanism 40 is inserted into the cabin casting 10, when viewed axially, the limiting sliders 41 are aligned with the limiting slots 25. During the insertion of the extraction and unloading mechanism 40, the limiting sliders 41 are inserted axially into the limiting slots 25, and when viewed vertically, the limiting post 24 is located between the two limiting sliders 41. When the extraction mechanism 40 pulls the inner mold insert 20 along the vertical axis, the limiting groove 23 exits the limiting protrusion 12, and the limiting post 24 exits the limiting through hole 13, so as to separate the inner mold insert 20 from the cabin casting 10 in the axial direction.

[0044] Specifically, during the casting process, the limiting groove 23 of the inner mold insert 20 cooperates with the limiting protrusion 12 of the cabin casting 10 to form a protruding structure on the inner wall of the casting. After casting, the limiting groove 23 and the limiting protrusion 12 form a radial engagement, preventing the inner mold insert 20 from being directly pulled out along the axial direction of the cabin casting 10.

[0045] The limiting through hole 13 on the limiting protrusion 12 extends through the cabin casting 10 along the vertical axis, and the limiting post 24 in the limiting groove 23 of the inner mold insert 20 extends into the through hole to form a positioning fit. This prevents the inner mold insert 20 from shifting vertically under the impact of high temperature, ensures the alignment of the limiting protrusion 12 and the limiting groove 23, and improves the molding accuracy; it further restricts the relative movement of the inner mold insert 20 and the cabin casting 10, avoids the inner mold insert 20 from loosening due to vibration, and ensures the structural stability of the casting during the cooling process.

[0046] Furthermore, the limiting groove 25 provides an axially aligned guide and force transmission structure for the extraction and unloading mechanism 40, serving as the specific interface for the guide rail connection between the inner mold insert 20 and the extraction and unloading mechanism 40. The limiting groove 25 extends axially along the inner surface 22 of the inner mold insert, allowing the limiting slider 41 of the extraction and unloading mechanism 40 to slide smoothly into the insert, forming an axial sliding pair.

[0047] The position of the limiting groove 25 is directly opposite to the limiting groove 23 and the limiting post 24 on the outer surface 21 of the inner mold insert 20. This ensures that when the extraction and unloading mechanism 40 is working, the limiting slider 41 is embedded in the limiting groove 25, so that the force of the extraction and unloading mechanism 40 can be directly transmitted to the engaging part of the inner mold insert 20, that is, the connection between the limiting groove 23 and the limiting post 24, thus avoiding uneven force on the inner mold insert 20 during extraction and unloading, which could lead to deformation or jamming.

[0048] Furthermore, the limiting slider 41 is the core execution component that physically connects the extraction and unloading mechanism 40 with the inner mold insert 20 and transmits force. The number and position of the limiting slider 41 are adapted to the number and position of the limiting slot 25.

[0049] By inserting the limiting slider 41 into the limiting slot 25, a sliding fit along the axial direction is formed. After the limiting slider 41 is fully inserted into the limiting slot 25, the limiting post 24 is located between the two limiting sliders 41, making the pulling force distribution more even and preventing excessive local stress on the insert from causing damage. Pulling the limiting slider 41 along the vertical axis transmits the huge horizontal separation force to the inner mold insert 20. The space formed between the two sliders is used to accommodate and avoid the limiting post 24.

[0050] In the initial stage of inserting the extraction mechanism 40 into the inner cavity of the cabin casting 10, the limiting slider 41 of the extraction mechanism 40 is pre-adjusted to be roughly aligned with the limiting slot 25 on the inner mold insert 20 by the operation and guidance of the mechanical crane 30, which avoids hard collisions during the insertion process and improves the smoothness of operation and the safety of the equipment mold.

[0051] Under the action of horizontal separation force, that is, separation force along the vertical axis, the inner mold insert 20 is pulled horizontally, and the limiting groove 23 on its outer surface 21 gradually disengages from the limiting protrusion 12 on the inner surface 11 of the cabin casting. As the inner mold insert 20 moves horizontally, the limiting post 24, which was originally inserted into the upper limiting through hole 13 of the cabin casting 10, is pulled out of the limiting through hole 13 at the same time. When the limiting groove 23 is completely disengaged from the limiting protrusion 12 and the limiting post 24 is completely withdrawn from the limiting through hole 13, the separation is completed and all the engagement and connection relationships between the inner mold insert 20 and the cabin casting 10 are completed.

[0052] In one specific embodiment, the limiting groove 25 extends axially downward from the upper end of the inner mold insert 20, and the upper end of the inner mold insert 20 is formed with a first screw hole 26. When viewed axially, the first screw hole 26 is arranged adjacent to the limiting groove 25. The extraction and unloading mechanism 40 includes: a support body 42 that is inserted into the cabin casting 10 along the axial direction, and a rotating connector 43 that is rotatably connected to the support body 42 at one end and connected to the first screw hole 26 by screws 45 at the other end. The rotating connector 43 has a U-shaped hole 431 that is formed through the axial direction. Before the extraction mechanism 40 is inserted into the cabin casting 10, the limiting slider 41 is aligned with the limiting slot 25 of the inner mold insert 20. When viewed along the axial direction, the rotating connector 43 rotates to a position that is offset from the inner mold insert 20. When the extraction mechanism 40 is inserted into the cabin casting 10 and the inner mold insert 20 is pulled out to separate it from the cabin casting 10 in the vertical axis, the rotating connector 43 rotates to the position corresponding to the inner mold insert 20, and rotates to the position of the U-shaped hole 431 corresponding to the position of the first screw hole 26. Before lifting the extraction mechanism 40 and its connected inner mold insert 20 along the axial direction, screws 45 are first inserted into the U-shaped hole 431 and the first screw hole 26 in sequence to connect the rotating connector 43 and the inner mold insert 20.

[0053] Specifically, the limiting groove 25 extends axially downward from the upper end of the inner mold insert 20, near the opening end of the cabin, providing an axial insertion channel for the limiting slider 41 of the extraction and unloading mechanism 40. Since the cabin casting 10 is mostly a cylindrical structure with an open upper end, the downward extension path of the limiting groove 25 provides sufficient mating length for the limiting slider 41, avoiding conflict between the extension direction of the limiting groove 25 and the insertion path of the limiting slider 41, reducing jamming during insertion, and improving docking efficiency.

[0054] The first screw hole 26 is a rigid connection point between the inner mold insert 20 and the extraction mechanism 40. It is located at the upper end of the inner mold insert 20 and adjacent to the limiting slot 25, which facilitates the operation of the screw 45 from above. This allows for subsequent connection with the first screw hole 26 via the screw 45, thereby fixing the rotating connecting piece 43 between the inner mold insert 20 and the extraction mechanism 40.

[0055] The supporting body 42 is the core skeleton of the extraction and unloading mechanism 40, bearing components such as the limiting slider 41 and the rotating connector 43, and transmitting lifting and separation forces. The rotating connector 43 is a key component for lifting and fixing the inner mold insert 20. It allows the rotating connector 43 to rotate horizontally relative to the supporting body 42. The rotating connector 43 is fastened to the first screw hole 26 of the inner mold insert 20 by screws 45. This provides strong axial constraint force, which, together with the circumferential and horizontal force constraints provided by the limiting slider 41, forms a double lock, completely eliminating the risk of the inner mold insert 20 becoming loose during lifting.

[0056] In the initial stage of equipment insertion into the cabin casting 10, the rotating connector 43 is pre-rotated to prevent it from colliding or interfering with the top of the inner mold insert 20. This avoids collisions between the rotating connector 43 and the top structure of the inner mold insert 20 during insertion, protecting the equipment and mold, and ensuring smooth and safe insertion. Before hoisting the separated inner mold insert 20, the rotating connector 43 is rotated to the position corresponding to the inner mold insert 20. It is then secured with screws 45 through the U-shaped hole 431 engaging with the first screw hole 26, ensuring that the inner mold insert 20 does not fall off during axial hoisting and improving the safety of hoisting high-temperature heavy components.

[0057] After casting, the cabin casting 10 and the inner mold insert 20 will undergo slight deformation due to thermal expansion and contraction. The opening design of the U-shaped hole 431 allows for a deviation of ±1-2mm in the insertion position of the screw 45, avoiding connection failure due to excessive rigidity alignment requirements and improving operational convenience.

[0058] When the limiting slider 41 is inserted into the limiting slot 25, it provides circumferential positioning, anti-torsion, and horizontal force transmission capabilities. After the screw 45 is locked into the first screw hole 26 via the rotating connector 43, it provides a strong axial constraint force for the inner mold insert 20, preventing the insert from loosening axially during hoisting.

[0059] In one specific embodiment, the unloading mechanism 40 further includes a hydraulic cylinder 44 corresponding to the limiting slider 41, wherein the sliding guide surface 411 of the limiting slider 41 is arranged axially, and the limiting slider 41 and the hydraulic cylinder 44 are arranged opposite to each other on opposite sides of the support body 42 along the vertical axis. The support body 42 extends axially, and a mounting groove 423 is formed on one side of the support body 42. The hydraulic cylinder 44 is disposed in the mounting groove 423. The mounting groove 423 extends recessedly from one side of the support body 42 to the other side. A push rod hole 424 extending vertically through the mounting groove 423 to the other side is formed. The limiting slider 41 is disposed on the other side. The push-pull rod 441 of the hydraulic cylinder 44 extends through the push rod hole 424 to the other side of the support body 42 and is connected to the limiting slider 41 vertically. When the limiting slider 41 is inserted into the limiting slot 25, the position of the limiting slider 41 in the vertical axis is recorded as the first position. After the limiting slider 41 causes the inner mold insert 20 to separate from the cabin casting 10 in the vertical axis, the position of the limiting slider 41 in the vertical axis is recorded as the second position. The hydraulic cylinder 44 outputs power to the push-pull rod 441, and the push-pull rod 441 pulls the limiting slider 41 from the first position to the second position, or the push-pull rod 441 pushes the limiting slider 41 from the second position to the first position.

[0060] Specifically, the hydraulic cylinder 44 serves as the power source for the extraction and unloading mechanism 40. The thrust or pull force output by the hydraulic cylinder 44 directly drives the limiting slider 41 to move along the vertical axis, providing a greater separation force for the separation of the inner mold insert 20 from the cabin casting 10. The direction of the vertical axis arrangement is consistent with the direction of the pulling action, reducing energy loss during force transmission, improving force utilization efficiency, and ensuring efficient execution of the separation action.

[0061] The sliding guide surface 411 of the limiting slider 41 is arranged along the axial direction of the cabin to ensure that the limiting slider 41 moves axially and is smoothly inserted into the limiting slot 25. Furthermore, when the limiting slider 41 moves vertically along the axial direction, it only slides in a preset direction, limiting the excess degrees of freedom of the limiting slider 41 and preventing the slider from twisting or shifting due to force during pulling. This ensures that the inner mold insert 20 separates smoothly along a preset horizontal direction, preventing scratches on the inner wall of the casting or jamming of the insert due to force deviation, and ensuring the structural strength of the casting. Simultaneously, the limiting slider 41 cooperates with the limiting slot 25 of the inner mold insert 20 to transmit the force of the hydraulic cylinder 44 to the inner mold insert 20 through the limiting slider 41, driving the separation of the inner mold insert 20 from the cabin casting 10.

[0062] Furthermore, the support body 42 is the mounting carrier of the extraction and unloading mechanism 40, extending along the axial direction of the cabin casting 10 to adapt to the length of the cabin casting 10. Limiting sliders 41 and hydraulic cylinders 44 are respectively arranged on its two opposite sides. The space integration and force transmission of the two are realized through the mounting groove 423 and the push rod hole 424, so that the force generated by the hydraulic cylinder 44 is transmitted to the limiting slider 41 in a straight line through the push-pull rod 441, thereby making the force transmission path short, efficient and low loss.

[0063] The mounting groove 423 is recessed from one side of the supporting body 42 to the other to accommodate the hydraulic cylinder 44, reducing the space occupied by the hydraulic cylinder 44 in the radial direction, i.e., the vertical axis, improving space utilization, and avoiding interference with the inner wall of the cabin casting 10. The push rod hole 424 extends through both sides of the supporting body 42 along the vertical axis, allowing the push-pull rod 441 of the hydraulic cylinder 44 to pass through and connect to the limiting slider 41.

[0064] Furthermore, the first position is the initial position when the limiting slider 41 is inserted into the limiting slot 25. At this time, the limiting slider 41 and the limiting slot 25 are fully engaged, and the inner mold insert 20 is still connected to the cabin casting 10 through the engagement of the limiting protrusion 12, the limiting groove 23, the limiting post 24, and the limiting through hole 13. The second position is the position after the limiting slider 41 drives the inner mold insert 20 connected to it to separate from the cabin casting 10. At this time, the limiting groove 23 exits the limiting protrusion 12, the limiting post 24 exits the limiting through hole 13, and the inner mold insert 20 and the cabin casting 10 are completely separated axially. After the inner mold insert 20 is separated from the cabin, the rotating connector 43 is rotated and aligned, and the inner mold insert 20 is fixed by the screw 45. The mechanical crane 30 lifts the separated inner mold insert 20 to the unloading area. Subsequently, the hydraulic cylinder 44 pushes and pulls the rod 441, driving the limit slider 41 to reset from the second position to the first position, preparing for the insertion and withdrawal of the next inner mold insert 20. The reset action is completed automatically without manual intervention, improving the efficiency of the cycle operation.

[0065] In one specific embodiment, the limiting slider 41 includes: a connecting part 412 connected to the push-pull rod 441, and a sliding part 413 integrally formed with the connecting part 412 and slidably connected with the limiting slot 25, wherein the sliding guide surface 411 is formed on the side of the sliding part 413 facing the limiting slot 25; Viewed along the axial direction, the width of the sliding part 413 on the side away from the connecting part 412 is greater than the width of the sliding part 413 on the side closer to the connecting part 412. The side with the larger width is called the outer side, and the side with the smaller width is called the inner side. The sliding part 413 forms an abutment surface 414 that gradually converges from the outer side to the inner side. When the unloading mechanism 40 pulls the inner mold insert 20 along the vertical axis, the abutment surface 414 abuts against the limiting groove 25 to pull the inner mold insert 20 apart from the cabin casting 10.

[0066] Specifically, the connecting portion 412 of the limiting slider 41 serves as the connection interface between the limiting slider 41 and the push-pull rod 441, bearing and transmitting the enormous tensile or pushing force from the push-pull rod 441. The sliding portion 413, integrally formed with the connecting portion 412, is the part that provides physical contact and transmits separation force between the limiting slider 41 and the limiting groove 25 of the inner mold insert 20. The integral forming eliminates connecting parts such as screws 45 and welds between the connecting portion 412 and the sliding portion 413, avoiding the risk of these connecting parts becoming fatigue fracture points under huge alternating loads, and significantly improving the overall structural strength and fatigue life of the slider. The sliding guide surface 411 is the working surface where the limiting slider 41 mates with the limiting groove 25, responsible for guiding the limiting slider 41 to move axially along the limiting groove 25 and bearing the constraint reaction force from the limiting groove 25.

[0067] Furthermore, the sliding part 413 is in the horizontal plane and has a trapezoidal or wedge-shaped structure with the connecting part 412. When the limiting slider 41 is subjected to separation tension, the larger width on the outer side provides a larger material cross section, which significantly reduces the stress level in the outer area and prevents the limiting slider 41 from breaking or plastically deforming due to stress concentration at the point of maximum force.

[0068] When the unloading mechanism 40 is inserted into the cabin along the axial direction, the sliding part 413 of the limiting slider 41 first contacts the limiting slot 25 of the inner mold insert 20. The outer wide side guides the sliding part 413 to slide smoothly into the limiting slot 25. The sliding guide surface 411 fits against the inner wall of the limiting slot 25, ensuring that the limiting slider 41 only moves along the axial direction.

[0069] When a separation force is applied, the limiting slider 41 tends to be pulled away from the limiting groove 25. The abutment surface 414 causes the pulling force acting on the inclined surface to generate a normal component force perpendicular to the inclined surface. This normal component force forces the slider to press more tightly against the inner wall of the limiting groove 25, thereby ensuring that the abutment surface 414 of the limiting slider 41 and the limiting groove 25 are tightly fitted under stress, preventing the limiting slider 41 from accidentally dislodging from the limiting groove 25 under huge separation forces. Furthermore, the abutment surface 414 increases the effective contact area between the sliding part 413 and the limiting groove 25, significantly reducing the peak contact stress on the contact surface. This greatly reduces the risk of plastic deformation, crushing, or wear of the limiting slider 41 and the limiting groove 25 in the high-pressure contact area.

[0070] In one specific embodiment, the support body 42 includes: a limiting support 421 that forms a limiting position with the positioning seat 50 in the axial direction of the vertical cabin casting 10, and an mounting support 422 that extends axially upward from the limiting support 421. The mounting groove 423 is formed on the mounting support 422. When viewed axially, the limiting support 421 is circular. The two sides of the mounting support 422 are recessed towards the center to form two opposing mounting surfaces. The mounting groove 423 is formed on one of the mounting surfaces, and the push rod hole 424 extends through to the other mounting surface. The positioning seat 50 includes: a first positioning step 51 that supports the external platform 60, a second positioning step 52 that extends axially upward from the first positioning step 51, and a central limiting hole 53 that passes through the first positioning step 51 and the second positioning step 52. The limiting support 421 is inserted into the central limiting hole 53 and fits against it to form a limiting position axially upward on the vertical cabin casting 10. A supporting ramp 54 is formed between the second positioning step 52 and the first positioning step 51. When the cabin casting 10 is transferred from the pallet 70 to the positioning seat 50 by the mechanical crane 30, the inner wall of the cabin casting 10 cooperates with the supporting ramp 54 to form a support.

[0071] Specifically, the limiting support 421 is a rigid connection node between the support body 42 and the positioning seat 50. Viewed axially, it is circular. The circular limiting support 421 can be inserted into the central limiting hole 53 of the positioning seat 50 and tightly fitted against its inner wall, restricting the horizontal translation or rotation of the support body 42. When the extraction mechanism 40 pulls the inner mold insert 20 along the vertical axis, the limiting support 421 transmits the reaction force through its fit with the central limiting hole 53, preventing the support body 42 from displacing itself.

[0072] The mounting surfaces are cut inwards on both sides of the mounting support 422, i.e., towards the center, forming two parallel, opposite concave planes. This concavity significantly reduces the width of the mounting support 422 at its widest point, making it easier to insert into the inner cavity of the hull casting 10. One of the concave mounting surfaces is then used to machine the mounting groove 423 to accommodate the hydraulic cylinder 44. The push rod hole 424 at the bottom of the mounting groove 423 horizontally penetrates the entire thickness of the mounting support 422 and extends to the other concave mounting surface, thereby mounting the limiting slider 41.

[0073] Furthermore, the positioning post forms a stepped structure, with the first positioning step 51 responsible for support and fixation, and the second positioning step 52 responsible for supporting the casting. At the center of the positioning seat 50, a central limit is machined vertically through the first and second positioning steps 52 to provide a mating hole for the circular limit support 421, thereby achieving horizontal limit.

[0074] The first positioning step 51 is in direct contact with the external platform 60, such as the ground or workbench. The large-area support surface disperses the load, ensuring that the positioning seat 50 itself does not settle or tilt during operation.

[0075] The support ramp 54 is a sloping transition surface machined between the bottom edge of the second positioning step 52 and the top of the first positioning step 51. The support ramp 54 matches the inner wall contour of the cylindrical cabin. When the cabin casting 10 is placed on the positioning seat 50, the support ramp 54 plays a guiding and preliminary positioning role. The inner wall edge of the cabin casting 10 slides along the support ramp 54, making it easier to align with the final position.

[0076] When the mechanical crane 30 transfers the cabin to the positioning seat 50, the lower inner wall of the cabin contacts the supporting inclined surface 54, forming three or more points of support, which restricts the horizontal swaying of the cabin. The contact between the supporting inclined surface 54 and the inner wall of the casting helps to restrict the movement of the casting in the horizontal plane, achieves preliminary radial positioning and stability, and prevents the casting from swaying during separation.

[0077] In one specific embodiment, the mechanical crane 30 includes: Column 31 is fixed to the external platform 60; The swing arm 32 is rotatably connected to the column 31; The suspension rope 33 has one end connected to the swing arm 32 and the other end hanging naturally. A threaded connector 34 is fixed to the other end of the lifting rope 33. The top of the mounting support 422 is provided with a threaded lifting hole 425. The threaded connector 34 is screwed into the threaded lifting hole 425 to connect the mechanical crane 30 and the unloading mechanism 40. The rotating connector 43 is rotatably connected between the threaded connector 34 and the top of the limiting support 421.

[0078] Specifically, the column 31 is the load-bearing foundation of the mechanical crane 30. It is fixed to the ground, workbench or other platform by bolts or embedded parts, providing vertical rigid support for the swing arm 32, the lifting rope 33 and the unloading mechanism 40.

[0079] The swing arm 32 rotates to move the hoisting rope 33 and the unloading mechanism 40 connected to the hoisting rope 33 on the horizontal plane, thereby transferring the cabin casting 10 from the pallet 70 to the positioning seat 50 by rotating around the column 31, which facilitates transfer between multiple workstations.

[0080] The hoisting rope 33 transmits the lifting force and allows the unloading mechanism 40 of the suspended object a certain degree of freedom in the vertical direction. The hoisting rope 33 is extended or retracted by a winch or other drive device, which drives the unloading mechanism 40 to rise and fall along the axial direction. Thus, during lowering, the unloading mechanism 40 is sent into the cabin casting 10, and during lifting, the separated inner mold insert 20 and the unloading mechanism 40 are lifted out of the cabin casting 10.

[0081] The threaded connector 34 is typically a lifting ring or screw with external threads, fixed to the end of the lifting rope 33, and can be screwed into the threaded lifting hole 425 on the top of the installation support 422 of the extraction mechanism 40 to form a detachable rigid connection.

[0082] In one specific embodiment, the number of limiting sliders 41 is four, and they are arranged in pairs on the two sides opposite to the supporting body 42, so as to remove the two inner mold inserts 20 at the same time.

[0083] Specifically, in another embodiment, there are four limiting sliders 41, divided into two groups of two, which are respectively installed on two opposite mounting surfaces of the support body 42. Each group of limiting sliders 41 corresponds to a limiting slot 25 of an inner mold insert 20, and the two inner mold inserts 20 are symmetrically distributed along the diameter direction within the chamber. It should be noted that the two groups of limiting sliders 41 are pulled in opposite directions, so that the reaction forces on the support body 42 are equal in magnitude and opposite in direction, forming a force balance. The two groups of limiting sliders 41 can be simultaneously inserted into the corresponding limiting slots 25, and the hydraulic cylinder 44 outputs power synchronously to pull them in opposite directions, realizing the simultaneous separation of the two inner mold inserts 20. Compared with removing one inner mold insert 20 at a time, this improves the efficiency of a single operation.

[0084] In one specific embodiment, there are multiple limiting sliders 41, which are respectively disposed on multiple sides of the support body 42, so as to remove multiple inner mold inserts 20 at the same time.

[0085] Specifically, in another embodiment, there are three or more limiting sliders 41, which are respectively installed on multiple sides of the support body 42. Each slider corresponds to a limiting slot 25 of an inner mold insert 20, and the inner mold insert 20 is asymmetrically or uniformly distributed in the circumferential direction within the chamber. The cross-section of the support body 42 is polygonal, such as triangular or hexagonal, and each side is provided with an independent mounting slot 423, hydraulic cylinder 44 and limiting slider 41.

[0086] Example 2 This application provides a modular disassembly method for the internal structure of a cabin, used to remove multiple internal mold inserts 20 within a cabin casting 10. The method includes the following steps: S1. The mechanical crane 30 transfers the cabin casting 10 from the pallet 70 to the positioning seat 50; S2. The extraction and unloading mechanism 40 is inserted into the cabin casting 10 by the mechanical crane 30, and forms a limit with the positioning seat 50 in the vertical axis of the cabin casting 10. During the insertion process, it completes the guide rail connection with at least one inner mold insert 20 along the axis. S3. The extraction and unloading mechanism 40 pulls out the inner mold insert 20 along the vertical axis and connects it to the inner mold insert 20 along the axis by screws 45. S4. After the mechanical crane 30 lifts the unloading mechanism 40 and its connected inner mold insert 20 along the axial direction to unload and separate them, the unloading mechanism 40 is returned to the cabin casting 10, and the remaining inner mold inserts 20 are removed in sequence.

[0087] It is understood that the modular disassembly method of the internal structure of the cabin in Embodiment 2 is exactly the same as the modular disassembly equipment of the internal structure of the cabin in Embodiment 1. Therefore, the beneficial effects they can produce are exactly the same, and will not be repeated here.

[0088] Thus, the coordinated design of the mechanical crane 30, the extraction and unloading mechanism 40, and the positioning seat 50 achieves significant improvements: during insertion, the extraction and unloading mechanism 40 completes the guide rail connection with the inner mold insert 20 along the axial direction, and pulls the inner mold insert 20 along the vertical axis of the cabin casting 10. This is specifically adapted to the complex non-rotational structure where the inner wall protrusions create a locking relationship, solving the problem of insufficient structural suitability of existing equipment; the mechanical crane 30 undertakes heavy-load operations such as cabin transfer and lifting of the inner mold insert 20, while the extraction and unloading mechanism 40 achieves mechanized separation, replacing manual operation and significantly reducing labor intensity. This reduces the risk of personnel exposure to high-temperature environments, improving operational safety and efficiency. Meanwhile, the mechanical crane 30 can return the unloading mechanism 40 to the cabin to sequentially remove the remaining inner mold inserts 20, forming a continuous operation process that meets the removal requirements of multiple inner mold inserts 20. The vertical axis limiting design of the unloading mechanism 40 and the positioning seat 50 provides stable support for operations with large separation forces, ensuring reliability under high-temperature conditions. Ultimately, this achieves efficient, safe, and stable removal of multiple inner mold inserts 20 within the cabin casting 10, significantly improving the automation level and production efficiency of casting production.

[0089] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
