Description

Technical Field

[0001] This utility model relates to the field of automatic demolding device technology, and in particular to an automatic demolding device for rubber ring processing. Background Technology

[0002] An automatic demolding device for rubber ring processing is a specialized piece of equipment used in the production process of rubber rings to automatically remove the molded rubber rings from the mold and to achieve subsequent automated transportation and transfer. Through the combination of mechanical structure and automated control, it replaces the traditional manual demolding method, improves production efficiency, reduces labor costs, and ensures the integrity and consistency of the rubber ring demolding process.

[0003] After demolding, rubber rings in traditional equipment usually fall directly onto the workbench or collection box, requiring manual picking and transfer to the next process, such as inspection or packaging. This increases labor costs and can easily lead to contamination or secondary deformation of the rubber rings due to human contact. When processing rubber rings of different diameters and thicknesses, traditional equipment requires changing the ejector pin position, adjusting the mold size, or even replacing the entire ejection assembly, which is time-consuming and labor-intensive. Furthermore, the adjustment accuracy depends on manual experience, which can easily lead to product inconsistency.

[0004] Therefore, in view of the problems of the above-mentioned traditional automatic demolding devices, such as the need for manual transfer after demolding, which increases labor costs, easy contamination or secondary deformation of products, and time-consuming and laborious adjustment when adapting to rubber rings of different specifications, and poor product consistency due to the reliance on manual experience for accuracy, it is necessary to design an automatic demolding device for rubber ring processing. Utility Model Content

[0005] To overcome the problems of traditional automatic demolding devices, such as the need for manual transfer after demolding, which increases labor costs, easy product contamination or secondary deformation, and time-consuming and labor-intensive adjustment when adapting to different specifications of rubber rings, and poor product consistency due to reliance on manual experience for accuracy.

[0006] The technical solution is as follows: An automatic demolding device for rubber ring processing includes a demolding base plate; a demolding processing table is installed on the upper end of the demolding base plate, a quick ejection component is installed on the lower end of the demolding processing table, a protective outer frame plate is installed on the upper end of the demolding base plate, a protective top plate is installed on the upper end of the protective outer frame plate, a molding device is installed on the protective top plate, a lifting and moving component is installed on the side of the molding device, a belt conveyor for transporting the processed rubber ring is installed on the side of the protective outer frame plate, a transverse clamping and transporting component is installed on the upper end of the protective outer frame plate, and the lifting and moving component includes an installation base plate installed on one side of the protective outer frame plate, a hydraulic lifting rod is installed on the upper end of the installation base plate, a linkage gate frame plate is installed at the output end of the hydraulic lifting rod, and the inner side of the linkage gate frame plate is connected to the outer side of the molding device.

[0007] Furthermore, the quick ejection assembly includes a support frame plate mounted on the upper part of the demolding base plate, a control box mounted on the bottom of the support frame plate, and a hydraulic ejection rod installed inside the control box.

[0008] Furthermore, a lifting plate is installed at the output end of the hydraulic ejector rod, and the output end of the hydraulic ejector rod extends through the support frame plate to the upper end of the support frame plate.

[0009] Furthermore, ejector vertical plates are fixedly connected to both sides of the upper end of the lifting plate, and ejector through slots are opened inside the demolding processing table for the ejector vertical plates to pass through.

[0010] Furthermore, the transverse clamping and transport assembly includes a limiting crossbeam plate installed on the inner side of the protective outer frame plate near the upper end, and a servo motor is installed on one end of the outer side of the limiting crossbeam plate.

[0011] Furthermore, an adjusting screw is installed at the output end of the servo motor, and a screw slider is threadedly connected to the outside of the adjusting screw. A transverse moving plate is fixedly connected to the side end of the screw slider.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an automatic demolding device for rubber ring processing, including a demolding base plate 1; a demolding processing table 2 is installed on the upper end of the demolding base plate 1, a quick ejection component is installed on the lower end of the demolding processing table 2, a protective outer frame plate 4 is installed on the upper end of the demolding base plate 1, a protective top plate 5 is installed on the upper end of the protective outer frame plate 4, a molding device 6 is installed on the protective top plate 5, a lifting and moving component is installed on the side of the molding device 6, and a belt conveyor 8 for transporting the processed rubber ring is installed on the side of the protective outer frame plate 4. The end is equipped with a transverse clamping and transporting component. The lifting and moving component includes a mounting base plate 701 installed on one side of the protective outer frame plate 4. A hydraulic lifting rod 702 is installed on the upper end of the mounting base plate 701. A linkage gate frame plate 703 is installed at the output end of the hydraulic lifting rod 702. The inner side of the linkage gate frame plate 703 is connected to the outer side of the molding device 6. The protective outer frame plate 4 is made of aluminum alloy profile splicing, which ensures structural rigidity and reduces the overall weight. The mounting groove reserved on its inner side can flexibly adapt to transverse clamping and transporting components of different specifications.

[0023] Please see Figures 3-5In this embodiment, the rapid ejection assembly includes a support frame plate 301 mounted on the upper end of the demolding base plate 1. A control box 302 is mounted on the bottom of the support frame plate 301, and a hydraulic ejection rod 303 is installed inside the control box 302. The hydraulic ejection rod 303 is driven by a servo hydraulic system, and the piston rod surface is chrome-plated, which improves wear resistance by more than 30%. Its maximum output force can reach 50kN, which can meet the ejection requirements of rubber rings with a diameter of up to 300mm. A dustproof sealing ring is installed at the penetration point between the hydraulic ejection rod 303 and the support frame plate 301, which can effectively prevent rubber debris from entering the hydraulic system and extend the service life of the equipment.

[0024] A lifting plate 304 is installed at the output end of the hydraulic ejector rod 303, and the output end of the hydraulic ejector rod 303 extends through the support frame plate 301 to the upper end of the support frame plate 301. A limit switch is installed on the upper surface of the support frame plate 301, which is automatically triggered when the lifting plate 304 rises to the set position to ensure consistent ejection height. The extension and retraction speed of the hydraulic ejector rod 303 can be adjusted by the flow valve of the control box 302. For rubber rings of different hardness, such as Shore hardness 60A-90A, the ejection speed can be set from 0.5-2mm / s. Soft rubber rings are ejected at a low speed to prevent deformation, while hard rubber rings are ejected at a high speed to improve efficiency.

[0025] Ejection vertical plates 305 are fixedly connected to both sides of the upper end of the lifting plate 304. The demolding processing table 2 has an ejection through slot 306 through which the ejection vertical plate 305 passes. The ejection through slot 306 is a rectangular through hole, and the clearance between it and the ejection vertical plate 305 is controlled between 0.05-0.1mm. This ensures that the ejection vertical plate 305 can move up and down smoothly and prevents the rubber material from overflowing from the gap during molding. The inner wall of the ejection through slot 306 is covered with a polytetrafluoroethylene wear-resistant layer with a friction coefficient of only 0.04, which can reduce the wear of the ejection vertical plate 305 during reciprocating motion and extend the maintenance cycle.

[0026] The transverse clamping and transport assembly includes a limiting cross frame plate 901 installed on the inner side of the protective outer frame plate 4 near the upper end. A servo motor 902 is installed on one end of the outer side of the limiting cross frame plate 901. The servo motor 902 is an AC servo motor with a braking function, with a rated speed of 3000 rpm. After being reduced by a planetary reducer, the output torque reaches 50 N·m, which can drive the adjusting screw 903 to run smoothly under load. The motor output shaft and the adjusting screw 903 are connected by a flexible coupling, which can compensate for the coaxiality error during installation and reduce transmission impact.

[0027] The output end of the servo motor 902 is equipped with an adjusting screw 903. The outer side of the adjusting screw 903 is threaded with a screw slider 904. The side end of the screw slider 904 is fixedly connected to a transverse moving plate 905. The side end of the screw slider 904 is connected to the transverse moving plate 905 by a T-bolt. A shock-absorbing pad is installed at the connection point to absorb the impact when the servo motor 902 starts and stops, and to prevent the rubber ring from shifting due to vibration during transportation. The transverse moving plate 905 has a hollow structure, which reduces weight while ensuring rigidity and reduces the load on the servo motor 902.

[0028] The inner side of the protective outer frame plate 4 is provided with a guide bar 907 corresponding to the limiting cross frame plate 901. The other side of the transverse moving plate 905 is equipped with a guide slider 906, and the guide slider 906 slides on the guide bar 907. The guide slider 906 is made of self-lubricating bearing material and contains solid lubricant. It can run continuously for more than 5,000 hours without maintenance.

[0029] A lifting cylinder 908 is installed at the upper end of the horizontal moving plate 905. A gripper 909 is installed at the output end of the lifting cylinder 908. The gripper 909 is an elastic gripper with anti-slip texture on its inner side to prevent damage to the surface of the rubber ring. The gripper 909 is made of food-grade silicone wrapped around a high-strength spring steel frame. The silicone layer with a Shore hardness of 50A ensures clamping force while preventing damage to the surface of the rubber ring. The anti-slip texture on the inner side of the gripper 909 is a diamond-shaped grid structure with a texture depth of 0.5mm, which increases the friction with the rubber ring and prevents slippage during gripping. At the same time, the gaps between the textures can accommodate small rubber debris to prevent contamination of the product surface. The opening and closing angle of the gripper 909 can be controlled by adjusting the cylinder stroke, with a maximum opening and closing angle of 60°, which is suitable for rubber rings with a diameter of 30-150mm.

[0030] Step 1: Equipment Inspection and Installation

[0031] Confirm that the demolding base plate 1 is placed stably, and calibrate it with a level to ensure the levelness of the entire device, so as to avoid wear of parts due to tilting during operation;

[0032] Check whether the connecting bolts between the protective outer frame plate 4 and the demolding base plate 1 are tight, and whether the installation of the protective top plate 5 and the protective outer frame plate 4 is in place, to ensure the stability of the closed frame structure;

[0033] Check whether the support frame plate 301 of the quick ejection assembly is fixed on the upper end of the demolding base plate 1, whether the connection between the hydraulic ejection rod 303 inside the control box 302 and the lifting plate 304 is firm, and whether the ejection vertical plate 305 is perpendicular to the upper end face of the lifting plate 304.

[0034] Check the transverse clamping and transport components: whether the limit cross frame plate 901 is in contact with the inner side of the protective outer frame plate 4, whether the adjusting screw 903 at the output end of the servo motor 902 is threadedly matched with the screw slider 904, whether the guide slider 906 can slide smoothly on the guide cross bar 907, whether the connection between the lifting cylinder 908 and the gripper 909 is flexible, and whether the anti-slip texture on the inner side of the gripper 909 is intact.

[0035] Parameter settings: The ejection force and ejection height of the hydraulic ejector rod 303 are set through the control box 302 and adjusted according to the hardness of the rubber ring. The pressure range of the ejection force is between 0.3-0.6MPa.

[0036] The hydraulic lifting rod 702 of the lifting and moving component is operated, and the mold closing pressure, heating temperature and mold opening height of the mold forming device 6 are set through the control panel;

[0037] Set the parameters of the lateral clamping and transport component: the lateral movement speed of the servo motor 902 is between 50-100mm / s, the extension and retraction stroke of the lifting cylinder 908, and the opening and closing force of the gripper 909.

[0038] Step Two: Automatic Operation Phase

[0039] Rubber ring molding

[0040] Rubber raw material is placed into the cavity of molding device 6. The equipment is started and the hydraulic lifting rod 702 of the lifting and moving component drives the linkage gate frame plate 703 to descend, causing the molding device 6 to fit with the demolding processing table 2 and close the mold.

[0041] The molding device 6 heats and pressurizes the rubber raw material according to the set parameters, so that the rubber raw material is vulcanized and molded. The molding time is set according to the thickness of the rubber ring, between 3 and 5 minutes.

[0042] Mold opening and ejection

[0043] After molding is completed, the hydraulic lifting rod 702 drives the linkage gate frame plate 703 to rise, and the molding device 6 moves up to open the mold until the mold opening position sensor is triggered.

[0044] After receiving the signal, the control box 302 starts the hydraulic ejection rod 303. Its output end pushes the lifting plate 304 to rise, and the ejection vertical plate 305 passes through the ejection slot 306 of the demolding processing table 2, pushing the rubber ring upward from the bottom of the mold cavity until the rubber ring is completely separated from the cavity. The hydraulic ejection rod 303 drives the lifting plate 304 to reset, and the ejection vertical plate 305 retracts into the ejection slot 306.

[0045] Clamping and transport

[0046] The lateral clamping and transport assembly is started: the servo motor 902 drives the adjusting screw 903 to rotate, and the screw slider 904 drives the lateral moving plate 905 to move along the guide bar 907, so that the gripper 909 is located directly above the rubber ring;

[0047] The lifting cylinder 908 extends, the gripper 909 descends to both sides of the rubber ring, the gripper 909 closes to grasp the rubber ring, and the pressure sensor ensures that the force is appropriate.

[0048] The lifting cylinder 908 retracts, the gripper 909 rises with the rubber ring, the servo motor 902 reverses the driving adjustment screw 903, and the horizontal moving plate 905 moves to directly above the belt conveyor 8.

[0049] The lifting cylinder 908 extends again, the gripper 909 opens, and the rubber ring is placed on the belt conveyor 8. Then the gripper 909 resets, and the transverse moving plate 905 returns to the top of the demolding processing table 2 to wait.

[0050] Subsequent transport

[0051] The belt conveyor 8 starts, transporting the rubber ring to the next process, such as size inspection and surface quality inspection, completing a single demolding cycle.

[0052] Step 3: Completion and Maintenance

[0053] After production is completed, turn off the heating system of the molding device 6. After the temperature drops to room temperature, operate the hydraulic lifting rod 702 to reset the molding device 6.

[0054] Turn off the power components such as the servo motor 902 and the hydraulic ejector rod 303, and disconnect the power supply to the control box 302.

[0055] Clean the surface of the demolding table 2 and the rubber debris in the ejection groove 306, and apply lubricant to maintain the sliding of the ejection vertical plate 305;

[0056] Check the inside of the 909 gripper for any rubber residue, clean it, and then spray with rust inhibitor;

[0057] Lubricating grease should be applied to moving parts such as adjusting screw 903 and guide bar 907 to ensure smooth lateral movement.

[0058] Check the oil pipe interfaces of the hydraulic lifting rod 702 and hydraulic jacking rod 303 for oil leaks, and replace the seals in a timely manner.
