[0009] The guide rail support system includes a load-bearing guide rail bracket and a hydraulic cylinder guide rail bracket, which are used to support and guide the movement of the hydraulic ejection system and the end cover chuck structure during the disassembly process of the tube mold.

[0010] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the above-mentioned automatic mold dismantling system for tube molds, the end cap chuck structure includes a chuck seat, a connecting rod sliding seat, three sets of claws, a side pull rod and a connecting rod. The three sets of claws are all hinged to the connecting rod sliding seat through the connecting rod, and the three sets of claws are all hinged on the chuck seat. The connecting rod sliding seat is connected to the side pull rod and is used to drive the connecting rod to realize the opening and closing of the three sets of claws under the drive of the side pull rod.

[0011] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: for the above-mentioned automatic mold dismantling system for tube molds, sliding plates are installed on both sides of the chuck seat to provide support and transmit force.

[0012] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the above-mentioned automatic mold dismantling system, a push plate bracket that cooperates with the side pull rod is connected to the piston rod end of the mold dismantling cylinder. When the mold dismantling cylinder extends, it drives the push plate bracket to move, and drives the chuck seat to move through the side pull rod, so as to realize the merging and dragging of the three sets of chucks; similarly, the retraction of the mold dismantling cylinder can realize the opening of the three sets of chucks and their approach to the mold end cap.

[0013] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the above-mentioned automatic mold dismantling system, a cylinder mounting bracket is connected to the cylinder of the mold dismantling cylinder, and the cylinder mounting bracket is connected to a cylinder pre-embedded bracket through several cylinder intermediate brackets.

[0014] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: For the above-mentioned automatic mold dismantling system, an exhaust pipe is installed separately above the oil cooler to exhaust hot air to the outside. The air intake and exhaust ports are independently separated to prevent the exhaust hot air from being recirculated to the air intake.

[0015] The technical problem to be solved by the present invention can also be further achieved through the following technical solutions: For the above-mentioned automatic mold dismantling system, the electrical control subsystem is operated by panel buttons and / or remote control to control the hydraulic pump source, the reciprocating motion of the oil cylinder, the oil cylinder stroke and oil source parameter monitoring.

[0017] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the above-mentioned automatic pipe mold dismantling system, an automatic pipe mold dismantling method is provided, the steps of which are as follows:

[0018] (1) Preparation stage

[0019] Place the formed tube mold on the demolding base and ensure that the tube mold is stably installed on the tube mold support.

[0020] (2) Preparation of the tie rod disassembly system

[0021] The end cap chuck structure of the tie rod disassembly system is installed on the demolding cylinder of the hydraulic ejection system to ensure that the end cap chuck can accurately clamp the end cap of the tube mold. The hydraulic pump station system is started through the electrical control subsystem to provide hydraulic oil to the demolding cylinder in preparation for the end cap dragging operation.

[0022] (3) Pulling the rod and removing the end cap

[0023] Under the control of the electronic control subsystem, the electromagnetic reversing valve is switched to drive the demolding cylinder to perform telescopic movement. Under the action of the hydraulic ejection system, the end cap chuck structure completes the clamping operation of the tube mold end cap and drags the pull rod to move the tube mold end cap until the tube mold pull rod is completely pulled out.

[0024] (4) Tube mold support and disassembly:

[0025] During the dragging process, the guide rail support system supports and guides the movement of the end cover chuck structure, ensuring the smooth disassembly process;

[0026] As the tube mold tie rod is fully pulled out, the tube mold remains stable under the support of the demolding base. The tube mold can then be removed from the demolding base by other auxiliary equipment or manual means.

[0027] (5) System reset and subsequent operations:

[0028] After demolding is completed, the demolding cylinder is retracted by the electrical control subsystem to reset the end cap chuck structure.

[0029] Shut down the hydraulic pump station system, stop the hydraulic oil supply, and perform necessary cleaning and maintenance on the system;

[0030] Prepare for the next round of mold removal.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. This automatic pipe mold dismantling system integrates a dismantling base, a tie rod dismantling system, a hydraulic pump station system, and a guide rail support system to automate the pipe mold dismantling process. Furthermore, the end cap chuck structure and hydraulic ejection system in the tie rod dismantling system can precisely clamp the pipe mold end cap and drag the tie rod, greatly reducing the complexity and time cost of manual operation. At the same time, the design of the electromagnetic reversing valve and buffer device makes the movement of the dismantling cylinder more stable and faster, further improving the dismantling efficiency.

[0033] 2. The design of the demolding base of the present invention fully considers the stress situation of the tube mold during the demolding process. The vertical support plate and the horizontal baffle effectively bear the vertical gravity and horizontal drag force of the tube mold, ensuring the stability of the demolding process. In addition, the buffer devices at both ends of the hydraulic ejection system can reduce the impact and vibration when the cylinder moves, protecting the system from damage. The oil cooling subsystem in the hydraulic pump station system independently circulates and cools the hydraulic oil, effectively preventing system failure caused by excessive oil temperature, and further enhancing the safety and reliability of the system.

[0034] 3. The hydraulic pump station system of the present invention adopts an upper and lower layout structure of oil tank and motor pump group, which makes the whole system structure compact and occupies a small area, making it easy to install and use in a limited space. At the same time, the oil cooling subsystem realizes independent circulation cooling of hydraulic oil by separately leading the inlet and outlet oil ports to the oil cooler, which not only improves the cooling efficiency, but also facilitates the maintenance and upkeep of the system. The design of the guide rail support system also fully considers the guidance and support requirements during the disassembly process, making the movement of the end cover chuck structure smoother and more stable, reducing the complexity and cost of system maintenance.

[0037] Figure 3 is a schematic diagram of the end cap chuck structure of the present invention. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Referring to Figures 1-3, an automatic mold dismantling system for pipe molds includes a mold dismantling base, a tie rod dismantling system, a hydraulic pump station system, and a guide rail support system.

[0040] The demolding base is used to support and fix the formed pipe mold. It is mainly made of Q235 steel plate with a thickness of 30mm and welded together. The design load is not less than 80 tons. The demolding base includes a pipe mold support seat 1 and a support seat fixing pre-embedded bracket 2. The pipe mold support seat 1 is used to install on the support seat fixing pre-embedded bracket 2. The pipe mold support seat 1 is also provided with a vertical support plate and a horizontal baffle for bearing the vertical gravity and horizontal drag force of the pipe mold.

[0041] The tie rod disassembly system includes an end cap chuck structure 6 and a hydraulic ejection system. The end cap chuck structure 6 is installed on the hydraulic ejection system and is used to complete the clamping and dragging operation of the tube mold end cap through the end cap chuck under the action of the hydraulic ejection system. For the disassembly of an 8m long tie rod, the hydraulic ejection system is designed with an ejection force of 100 tons and a maximum ejection force of 160 tons. Specifically:

[0042] The end cap chuck structure 6 includes a chuck seat 61, a connecting rod 64 sliding seat 62, three sets of jaws 63, a side pull rod 65, and a connecting rod 64. The three sets of jaws 63 are all hinged to the connecting rod 64 sliding seat 62 through the connecting rod 64, and the three sets of jaws 63 are all hinged to the chuck seat 61. The connecting rod 64 sliding seat 62 is connected to the side pull rod 65 and is used to drive the connecting rod 64 to open and close the three sets of jaws 63 under the drive of the side pull rod 65. In use, before clamping the end cap, the jaws 63 are first controlled to open. The two side pull rods 65 need to be controlled to advance, drive the connecting rod 64 sliding seat 62 to move, and then the jaws 63 are opened through the connecting rod 64. When the side pull rod 65 limiting plate contacts the chuck seat 61, it will further push the chuck seat 61 to move together until the jaws 63 reach the tube mold end cap position.

[0043] When the chuck 63 reaches the preset position of the mold end cap, it begins to pull back the side pull rod 65 in the opposite direction until the connecting rod 64 sliding seat 62 contacts the chuck seat 61. During this process, the three chucks 63 will gradually merge until the end completely locks the mold end cap. After that, when the side pull rod 65 is pulled to the left, the chuck system begins to drive the mold end cap to move to the left until the mold pull rod is completely pulled out.

[0044] Slide plates are installed on both sides of the chuck base 61 to provide support and transmit force;

[0045] Secondly, during the demolding process, the claw 63, as the direct force-bearing element between the mold end cap and the mold, experiences significant wear and deformation at its end. To avoid unnecessary waste from replacing the entire claw 63 structure after damage, the claw 63 is designed as two parts: a claw 63 connecting rod 64 and a claw 63 head. The claw 63 head is made of wear-resistant manganese steel alloy and is connected to the claw 63 connecting rod 64 via a perforated shaft, making replacement and disassembly convenient.

[0046] The hydraulic ejection system includes a demolding cylinder 10, which is installed and fixed by a cylinder fixing bracket 11. The hydraulic system is designed with a rated pressure of 21MPa, an inner diameter of 310mm, a piston rod diameter of 150mm, and a stroke of 8.3m. The demolding cylinder 10 is switched by an electromagnetic reversing valve and has buffer devices at both ends. Under normal working conditions, the cylinder retraction speed is 200mm / s and the ejection speed is 120mm / s. The system requires a flow rate of 543L / min. Therefore, two 250cc variable displacement pumps are selected to supply oil in parallel to meet the maximum flow rate requirement. When slow movement is required, only one pump can be kept in operation by switching the switch valve.

[0047] To improve the disassembly force of the tie rod, the design corresponds to the extended state of the hydraulic cylinder during the demolding process. A push plate bracket 7, which cooperates with the side tie rod 65, is connected to the piston rod end of the demolding cylinder 10 via a cylinder connecting bracket 8. When the demolding cylinder 10 extends, it drives the push plate bracket 7 to move, which in turn drives the chuck seat 61 to move via the side tie rod 65, thus merging and dragging the three sets of jaws 63. Similarly, the retraction of the demolding cylinder 10 allows the three sets of jaws 63 to open and move closer to the mold end cap. A demolding load-bearing guide rail 3 is also installed on the ground, cooperating with the push plate bracket 7. The demolding load-bearing guide rail 3 is pre-embedded and fixed via pre-embedded base I4 and pre-embedded base II5.

[0048] To increase the demolding load on the demolding cylinder 10 and reduce the lateral force between the piston rod and the cylinder, a cylinder mounting bracket 12 is connected to the cylinder of the demolding cylinder 10. The cylinder mounting bracket 12 is connected to a cylinder pre-embedded bracket 9 through several cylinder intermediate brackets.

[0049] The hydraulic pump station system is used to provide hydraulic oil for the demolding cylinder 10. The hydraulic pump station system includes three subsystems: pump station, oil cooling and electrical control. The pump station subsystem adopts an upper and lower layout structure of oil tank and motor pump group. The oil cooling subsystem 14 uses an oil cooler to independently circulate and cool the hydraulic oil in the oil tank. The oil tank has an inlet and outlet port separately led out to the oil cooler.

[0050] The motor pump unit and oil tank occupy approximately 3.5m in length, 2.74m in width, and 2.2m in height. The total space occupied by the oil cooler is 2.3m in length, 2m in width, and 3.9m in height. A separate exhaust pipe is installed above the oil cooler to exhaust hot air to the outside. The air intake and exhaust ports are independent to prevent the exhaust hot air from being recirculated to the air intake.

[0051] The electrical control subsystem 13 is operated via panel buttons and / or a remote control to control the hydraulic pump source, cylinder reciprocating motion, cylinder stroke, and oil source parameter monitoring. Specifically, the electrical control subsystem 13 also includes two subsystems: hydraulic oil source and tie rod disassembly. All components of the two subsystems share a single electrical control cabinet and PLC control center. This system mainly consists of a programmable controller and automatic control software. Manual or semi-automatic remote control of each system is achieved through communication between a handheld remote control and the PLC to complete the actions required for mold assembly.

[0052] Secondly, the electrical control cabinet also includes oil source power components and mold dismantling control components. The oil source power components include soft starters for the pump station motor and oil cooler motor, as well as system power supply components. The mold dismantling control components include pump station control components, oil cooler control components, and sensor signal acquisition components, etc. The cabinet is also connected to a remote control, emergency stop switch, alarm indicator light, operation buttons, and other wiring accessories.

[0053] According to the design requirements, the remote control button functions include: ejection / retraction of the mold disassembly cylinder 10, start / stop of the pump source motor, unloading / working of the pump source, emergency stop, etc. The buttons on the control panel of the industrial control cabinet also include start / stop of the pump source motor, unloading / working of the pump source, emergency stop, etc., to facilitate operation at both near and far distances.

[0054] The guide rail support system includes a load-bearing guide rail bracket 16 and a hydraulic cylinder guide rail bracket 15, used to support and guide the movement of the hydraulic ejection system and end cap chuck structure during the disassembly of the mold. A push plate that cooperates with the demolding cylinder 10 is also installed on the hydraulic cylinder guide rail bracket 15 via a locking nut 19. Considering transportation size limitations, it is divided into two identical parts on the left and right sides; the underground embedded bracket is also divided into two parts. To improve installation accuracy, the two underground parts are connected by steel plates via anchor bolts 17. In addition to the mechanical limit of the hydraulic cylinder itself, an electronic travel limit switch is installed at each end of the hydraulic cylinder guide rail bracket 15 to limit the extension and retraction range of the hydraulic cylinder during demolding.

[0055] An automatic demolding method for pipe molds includes the following steps:

[0056] (1) Preparation stage

[0057] The formed pipe mold is placed on the demolding base, which consists of a pipe mold support and a support fixed pre-embedded bracket to ensure that the pipe mold is stably installed on the pipe mold support, and that the vertical support plate and the horizontal baffle correctly bear the vertical gravity and horizontal drag force of the pipe mold.

[0058] (2) Preparation of the tie rod disassembly system

[0059] The end cap chuck structure of the tie rod disassembly system is installed on the demolding cylinder of the hydraulic ejection system to ensure that the end cap chuck can accurately clamp the end cap of the tube mold. The hydraulic pump station system is started through the electrical control subsystem to provide hydraulic oil to the demolding cylinder in preparation for the end cap dragging operation.

[0060] (3) Pulling the rod and removing the end cap

[0061] Under the control of the electronic control subsystem, the electromagnetic reversing valve is switched to drive the demolding cylinder to perform telescopic movement. Under the action of the hydraulic ejection system, the end cap chuck structure completes the clamping operation of the tube mold end cap and drags the pull rod to move the tube mold end cap until the tube mold pull rod is completely pulled out.

[0062] (4) Tube mold support and disassembly:

[0063] During the dragging process, the guide rail support system supports and guides the movement of the end cover chuck structure, ensuring the smooth disassembly process;

[0064] As the tube mold tie rod is fully pulled out, the tube mold remains stable under the support of the demolding base. The tube mold can then be removed from the demolding base by other auxiliary equipment or manual means.

[0065] (5) System reset and subsequent operations:

[0066] After demolding is completed, the demolding cylinder is retracted by the electrical control subsystem to reset the end cap chuck structure.

[0067] Shut down the hydraulic pump station system, stop the hydraulic oil supply, and perform necessary cleaning and maintenance on the system;
