Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and more specifically, to a hydraulic core mold for a tunnel lining product. Background Technology

[0002] In the field of ultra-large diameter shield tunnel construction, subway tunnel entrance components are key prefabricated components. They consist of a top side plane, two vertical sides and a bottom arc surface, with a cavity in the middle. The bottom arc surface can be closely attached to the circular tunnel, the top side plane can serve as the road surface, and the hollow cavity in the middle can provide for the laying of cables and pipelines while saving concrete. Therefore, they are widely used in urban tunnels. They need to be hoisted into place simultaneously during shield machine excavation and manually assembled, with concrete backfilled on both sides to form the road surface.

[0003] Existing door components are cast using large molds. The outer mold is a four-piece template assembly structure. Although the core mold can be tightened inwards during mold opening for easy demolding, both the outer mold and the core mold need to be lifted away by a hoist after mold opening. Moreover, the traditional core mold demolding requires three steps: "manually removing the fixing bolts - manually extending and retracting the core mold - lifting away with a hoist." This is not only time-consuming but also requires high technical skills from workers, significantly increasing the time and labor costs of door component prefabrication. In particular, the internal cavity space of the door component is limited, making core mold lifting even more technically challenging and time-consuming. With the advancement of urbanization, there is an urgent need to optimize the core mold design. Therefore, designing a hydraulic core mold for door components has great potential for widespread application. Utility Model Content

[0004] The present invention aims to provide a hydraulic core mold for slotted parts, in order to solve the problems of existing technologies that require manual bolt removal, manual extension and retraction, lifting with a hoist, which are time-consuming, require high technical skills from workers, and are time-consuming and labor-intensive.

[0005] The embodiments of this utility model are implemented as follows: This utility model embodiment provides a hydraulic core mold for a fitting product, which includes a core mold template; The aforementioned core mold template has a first large straight telescopic block, a first short straight rotating block, a second short straight rotating block, a first small arc rotating block, a second small arc rotating block, and an arc telescopic block. One end of the first short straight rotating block and the second short straight rotating block are respectively hinged to both ends of the first large straight telescopic block, and one end of the first small arc rotating block and the second small arc rotating block are respectively hinged to both ends of the arc telescopic block. The other ends of the first small arc segment rotating block and the second small arc segment rotating block respectively engage with the inclined surfaces of the other ends of the first short straight segment rotating block and the second short straight segment rotating block. The core mold template is equipped with a hydraulic telescopic system that drives the first large straight section telescopic block, the first short straight section rotating block, the second short straight section rotating block, the first small arc section rotating block, the second small arc section rotating block and the arc section telescopic block to swing or move.

[0006] In use, the hydraulic telescopic system first drives each cylinder to move in a set sequence, causing the first large straight telescopic block, the first short straight rotating block, the second short straight rotating block, the first small arc rotating block, the second small arc rotating block, and the arc telescopic block on the core mold template to unfold, so that the core mold template reaches the mold-closed state to meet the casting requirements of the opening component; after the opening component is cast, the hydraulic telescopic system controls each cylinder to move in the opposite direction, driving the first large straight telescopic block, the first short straight rotating block, the second short straight rotating block, the first small arc rotating block, the second small arc rotating block, and the arc telescopic block to retract, realizing the separation of the core mold template from the opening component and completing the demolding operation.

[0007] The hydraulic core mold for a perforated component disclosed in this embodiment adopts the aforementioned core mold template. Its main body is composed of the aforementioned first large straight section telescopic block, the aforementioned first short straight section rotating block, the aforementioned second short straight section rotating block, the aforementioned first small arc section rotating block, the aforementioned second small arc section rotating block, and the aforementioned arc section telescopic block, which are connected by hinges. It is equipped with the aforementioned hydraulic telescopic system containing multiple sets of oil cylinders, which can precisely control the telescopic and rotation of each module through hydraulic drive. It can not only realize the core mold to complete the mold closing and demolding in a set sequence efficiently, avoiding the cumbersome process of traditional manual operation, but also control the dimensional deviation through structural design to ensure the quality of the perforated component. Thus, the hydraulic core mold for a perforated component has the beneficial effects of mechanical telescopic without disassembling bolts, no need to adjust the template, short time, low technical requirements for workers, low time and labor costs, and saving time and labor.

[0008] Optionally: The bottom of the above-mentioned core mold template is provided with a first core mold traveling device, a second core mold traveling device, a third core mold traveling device and a fourth core mold traveling device, the first core mold traveling device and the second core mold traveling device are connected to the bottom end of the first large straight section telescopic block in parallel and at intervals. The aforementioned third core mold traveling device and the aforementioned fourth core mold traveling device are connected to the bottom end of the aforementioned arc-shaped telescopic block in parallel and at intervals.

[0009] This configuration provides stable and independent support and guidance for the first straight section telescopic block and the arc section telescopic block of the core mold template, effectively preventing the core mold template from shifting or shaking due to uneven support during telescopic and travel processes. This further improves the overall dimensional accuracy of the core mold template after mold closing to meet the requirements for manufacturing the opening component. At the same time, the regionally configured travel device can better adapt to the movement needs of the upper, middle, and lower three-layer structure and different modules of the core mold template, helping the hydraulic telescopic system to complete the mold closing and demolding operations more smoothly, reducing the travel resistance of the core mold template, thereby improving the prefabrication production efficiency of the opening component and reducing the manual adjustment costs and time consumption caused by travel failures.

[0010] Optionally, the first core mold traveling device, the second core mold traveling device, the third core mold traveling device and the fourth core mold traveling device all have guide rails and traveling rollers, and the traveling rollers are rotatably adapted to the guide rails.

[0011] This configuration allows for smooth rotation of the traveling rollers within the guide rails, significantly reducing frictional resistance during the movement of the core mold template. This makes the extension, retraction, and movement of the core mold template easier and smoother, preventing jamming or misalignment due to excessive resistance. It also ensures that the hydraulic extension system efficiently completes mold closing and demolding in the set sequence. Furthermore, the matching structure between the traveling rollers and the guide rails precisely limits the direction of travel, reducing offset errors during movement. This further assists in controlling the overall dimensions of the core mold template after mold closing, ensuring that the precast components meet the allowable deviation requirements for length, width, height, and diagonal differences. At the same time, it reduces the frequency of manual adjustments required due to movement malfunctions, thus reducing labor time and costs.

[0012] Optionally, the bottom of the aforementioned core mold template is further provided with a support frame, and the guide rails of the aforementioned first core mold traveling device, the aforementioned second core mold traveling device, the aforementioned third core mold traveling device, and the aforementioned fourth core mold traveling device are all welded to the aforementioned support frame.

[0013] This configuration provides a stable mounting base for the guide rails of each traveling device using the aforementioned support frame, preventing displacement or deformation of the guide rails during the movement and expansion of the core mold template due to insecure installation. This ensures the stable operation of the guiding and supporting functions of the traveling devices. Furthermore, the uniform welding of the structure to the support frame ensures the installation position accuracy of the four guide rails, maintains the parallelism and spacing between the traveling devices, further reduces the offset error of the traveling rollers within the guide rails, helps control the overall dimensional accuracy of the core mold template after mold closing to meet the requirements of the die component manufacturing, and improves the load-bearing stability of the overall core mold template structure. This prevents the core mold template from shaking due to insufficient support during operation, ensuring the smooth completion of mold closing and demolding operations by the hydraulic telescopic system, indirectly improving the prefabrication efficiency of the die component and reducing troubleshooting costs.

[0014] Optionally, the guide rails in the first core mold traveling device, the second core mold traveling device, the third core mold traveling device and the fourth core mold traveling device are all arranged along the same axial direction, and the traveling rollers in the guide rails move along the axial direction of the guide rails and are limited within the guide rails.

[0015] This configuration ensures, on the one hand, that the movement directions of the first, second, third, and fourth core mold traveling devices are highly consistent, preventing jamming or offset caused by directional deviations of the traveling devices during the extension, retraction, and travel of the core mold template, thus guaranteeing the overall stability of the core mold template's movement. On the other hand, the axial limiting design of the traveling rollers within the guide rails further restricts the lateral displacement of the core mold template during travel, significantly reducing travel offset errors and helping to control the overall dimensional accuracy after the core mold is closed, thereby meeting the allowable deviation requirements for the length and width of the component, reducing manual adjustment time caused by travel deviations, and indirectly improving the prefabrication production efficiency of the component.

[0016] Optionally: The above-mentioned hydraulic telescopic system includes a first left telescopic cylinder, a second left telescopic cylinder, a third left telescopic cylinder, a first right telescopic cylinder, a second right telescopic cylinder, and a third right telescopic cylinder; The two ends of the first left telescopic cylinder are respectively hinged to the first small arc segment rotating block and the arc segment telescopic block; the two ends of the second left telescopic cylinder are respectively hinged to the first short straight segment rotating block and the first large straight segment telescopic block; and the two ends of the third left telescopic cylinder are respectively hinged to the arc segment telescopic block and the support frame. The two ends of the first right telescopic cylinder are respectively hinged to the second small arc segment rotating block and the arc segment telescopic block. The two ends of the second right telescopic cylinder are respectively hinged to the second short straight segment rotating block and the first large straight segment telescopic block. The two ends of the third right telescopic cylinder are respectively hinged to the first large straight segment telescopic block and the support frame.

[0017] This configuration provides targeted driving force to the first large straight section telescopic block, the first short straight section rotating block, the second short straight section rotating block, the first small arc section rotating block, the second small arc section rotating block, and the arc section telescopic block of the core mold template. This ensures that each module can accurately perform telescopic or rotating actions as required, adapting to the requirements of cavity shape construction and demolding of the part. In addition, the symmetrical arrangement of hydraulic cylinders and the hinge design of the corresponding modules ensure that the core mold template is subjected to balanced forces on both sides, avoiding module offset or deformation due to uneven forces on one side. This ensures that the overall dimensional accuracy of the core mold template after mold closing meets the allowable deviation requirements of the part. At the same time, it helps the hydraulic telescopic system to smoothly complete mold closing and demolding in the set sequence, reducing adjustment time caused by module jamming or positional deviation, improving the prefabrication efficiency of the part, and reducing production failure costs.

[0018] Optionally, the first left telescopic cylinder, the second left telescopic cylinder, the third left telescopic cylinder, the first right telescopic cylinder, the second right telescopic cylinder, and the third right telescopic cylinder are all connected to an oil pump via hydraulic pipes, and the oil pump is electrically connected to the cylinder controller.

[0019] This configuration allows for precise control of the oil supply to the first, second, and third left telescopic cylinders, as well as the first, second, and third right telescopic cylinders, through the electronic control of the oil pumps via the cylinder controller. This control over the timing, speed, and amount of extension and retraction of these cylinders ensures that each module of the core mold completes its extension and rotation synchronously or sequentially, meeting the precise operational requirements for mold closing and demolding. Furthermore, the unified hydraulic pipe connection and electronic control system design replaces traditional manual operation, significantly reducing human intervention and mitigating the risk of dimensional deviations in the core mold caused by human error. It also improves cylinder response efficiency, shortens mold closing and demolding time, further reducing labor and time costs in prefabricating the core components, and ensuring a stable improvement in the production quality and efficiency of the core components.

[0020] Optionally: The core mold template has a three-layer structure (upper, middle, and lower), the outer side of the core mold template has a panel, and the inner side of the core mold template has a back rib plate.

[0021] This three-layer structure can accommodate different models of precast components. In addition, the outer panel can accurately construct the shape of the inner cavity of the precast component and ensure the dimensional accuracy of the inner cavity. The inner back rib plate can enhance the overall structural strength and rigidity of the core mold template, and prevent the core mold from deforming during hydraulic expansion and contraction and casting. This ensures that the precast precast components meet the allowable deviation requirements for length, width and other dimensions, while also extending the service life of the core mold and reducing product scrap or rework caused by template deformation, thereby indirectly improving production efficiency.

[0022] Optionally, the middle layer of the above-mentioned core mold template is provided with an adjustment block for adjusting the height of the model.

[0023] With this setup, the casting requirements of various sizes of fittings can be met by simply changing the adjusting block, eliminating the need to make separate core molds for different models and significantly reducing production equipment costs.

[0024] Optionally, the hinge joints of the first large straight section telescopic block, the first short straight section rotating block, the second short straight section rotating block, the first small arc section rotating block, the second small arc section rotating block, and the arc section telescopic block all have pins.

[0025] This configuration provides a stable rotation center for the hinged connections of the first large straight telescopic block, the first short straight rotating block, the second short straight rotating block, the first small arc rotating block, the second small arc rotating block, and the arc telescopic block. This ensures that each module of the core mold template can accurately telescopic or rotate around the pin shaft, adapting to the mold closing and demolding requirements driven by the hydraulic telescopic system. It also prevents misalignment or jamming at module connection points due to the lack of a fixed rotation center. Furthermore, the pin shaft connection method ensures the connection strength at the hinge points of each module, preventing module separation or loosening due to stress during operation. It also facilitates module disassembly and maintenance, indirectly improving the overall service life of the core mold template and further ensuring the dimensional accuracy and production efficiency of the precast components.

[0026] In summary, the hydraulic core mold for the opening component disclosed in this utility model has the advantages of mechanical telescopic movement without the need to disassemble bolts, no need to adjust the template, short processing time, low technical requirements for workers, low time and labor costs, and saving time and effort.

[0032] Example See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment proposes a hydraulic core mold for a part, including a core mold template 1; The core mold template 1 has a first large straight section telescopic block 2, a first short straight section rotating block 3, a second short straight section rotating block 4, a first small arc section rotating block 5, a second small arc section rotating block 6, and an arc section telescopic block 7. One end of the first short straight section rotating block 3 and the second short straight section rotating block 4 are respectively hinged to the two ends of the first large straight section telescopic block 2, and one end of the first small arc section rotating block 5 and the second small arc section rotating block 6 are respectively hinged to the two ends of the arc section telescopic block 7. The other ends of the first small arc segment rotating block 5 and the second small arc segment rotating block 6 respectively engage with the inclined surfaces of the other ends of the first short straight segment rotating block 3 and the second short straight segment rotating block 4. The core mold template 1 is equipped with a hydraulic telescopic system 8 that drives the first large straight section telescopic block 2, the first short straight section rotating block 3, the second short straight section rotating block 4, the first small arc section rotating block 5, the second small arc section rotating block 6, and the arc section telescopic block 7 to swing or move.

The third core mold traveling device 11 and the fourth core mold traveling device 12 are connected to the bottom end of the arc section telescopic block 7 in parallel and at intervals. This arrangement can provide stable and independent support for the first large straight section telescopic block 2 and the arc section telescopic block 7 of the core mold template 1, respectively. The guide effectively prevents the core mold template 1 from shifting or shaking due to uneven support during expansion, contraction, and travel, further improving the overall dimensional accuracy of the core mold template 1 after mold closing to meet the requirements of the component manufacturing.

[0038] The guide rails 13 in the first core mold traveling device 9, the second core mold traveling device 10, the third core mold traveling device 11, and the fourth core mold traveling device 12 are all arranged along the same axial direction. The traveling rollers 14 in the guide rails 13 move along the axial direction of the guide rails 13 and are limited within the guide rails 13.

[0041] The core mold template 1 has a three-layer structure (upper, middle, and lower). The outer side of the core mold template 1 has a panel 22, and the inner side of the core mold template 1 has a back rib plate 23. The three-layer structure can be adapted to different models of precast components. In addition, the outer panel 22 can accurately construct the shape of the inner cavity of the precast component and ensure the dimensional accuracy of the inner cavity. The back rib plate 23 on the inner side can enhance the overall structural strength and rigidity of the core mold template 1, and prevent the core mold from deforming during hydraulic expansion and contraction and casting stress. This ensures that the precast precast components meet the allowable deviation requirements for length, width, etc., while also extending the service life of the core mold, reducing product scrap or rework caused by template deformation, and indirectly improving production efficiency.

[0042] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The middle layer of the core mold template 1 is equipped with an adjustment block (not shown in the figure) for adjusting the height of the model. By replacing the adjustment block, the casting requirements of various sizes of parts can be met, eliminating the need to make separate core molds for different models and greatly reducing the cost of production equipment.

[0043] The hinge joints of the first large straight telescopic block 2, the first short straight rotating block 3, the second short straight rotating block 4, the first small arc rotating block 5, the second small arc rotating block 6, and the arc telescopic block 7 all have pins 24. This arrangement provides a stable rotation center for the hinged connections of the first large straight telescopic block 2, the first short straight rotating block 3, the second short straight rotating block 4, the first small arc rotating block 5, the second small arc rotating block 6, and the arc telescopic block 7. This ensures that each module of the core mold template 1 can accurately achieve telescopic or rotating movements around the pins 24, adapting to the mold closing and demolding requirements driven by the hydraulic telescopic system 8, and avoiding misalignment or jamming at the module connection points due to the lack of a fixed rotation center. In addition, the pin connection method ensures the connection strength of each module hinge joint, preventing the core mold template 1 from separating or loosening due to force during operation. It also facilitates module disassembly and maintenance, indirectly improving the overall service life of the core mold template 1, and further ensuring the dimensional accuracy and production efficiency of the precast components.

[0048] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the hydraulic telescopic system 8 mainly consists of a first left telescopic cylinder 16, a second left telescopic cylinder 17, a third left telescopic cylinder 18, a first right telescopic cylinder 19, a second right telescopic cylinder 20, a third right telescopic cylinder 21, an oil pump, and a cylinder controller, which serves as the main component for controlling the telescopic movement of the core mold of the orifice.

[0049] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the specific mold closing and demolding steps of the hydraulic core mold for the part are as follows: When the core mold template 1 is closed, the second left telescopic cylinder 17 and the second right telescopic cylinder 20 are extended first, then the first left telescopic cylinder 16 and the first right telescopic cylinder 19 are extended, and finally the third left telescopic cylinder 18 and the third right telescopic cylinder 21 are extended, thereby realizing the mold closing operation of the core mold template 1. After that, the connection device between the core mold template 1 and other opening parts is installed. When the core mold template 1 is demolded, the first left telescopic cylinder 16 and the first right telescopic cylinder 19 are retracted first, then the second left telescopic cylinder 17 and the second right telescopic cylinder 20 are retracted, and finally the third left telescopic cylinder 18 and the third right telescopic cylinder 21 are retracted, thereby realizing the demolding operation of the core mold template 1. After that, the connection device between the core mold template 1 and other opening parts is disassembled.
