Description

A rubber product demolding device Technical Field

[0001] This utility model relates to the field of rubber product demolding technology, and more specifically, to a rubber product demolding device. Background Technology

[0002] In the rubber product manufacturing industry, the efficiency, reliability, and flexibility of the demolding process are key factors affecting production efficiency. However, the demolding devices for rubber products currently on the market still have many technical defects in practical applications. These problems not only reduce production efficiency but may also affect product quality and equipment lifespan.

[0003] The primary problem is the outdated and inefficient demolding methods. Existing demolding methods have significant drawbacks: First, traditional manual demolding is labor-intensive; second, the manual demolding process is time-consuming, seriously affecting production efficiency; and third, the instability of manual operation can easily lead to product deformation or damage. These shortcomings of traditional demolding methods not only increase the workload of workers but may also affect product quality and reduce production efficiency due to improper operation.

[0004] More notably, the airflow demolding structure has significant defects. The simple airflow demolding device design used in the existing technology has obvious problems. The airflow hole structure directly opened on the mold core is too simple. The open airflow hole is easily blocked by rubber material during the molding process. The blocked airflow hole will cause demolding failure and requires frequent cleaning and maintenance. This design deficiency not only affects the reliability of demolding, but also increases equipment maintenance costs and reduces production continuity.

[0005] Most critically, the air pressure regulation mechanism is seriously inadequate. Although some equipment has realized the airflow demolding function, there are still obvious defects in practical applications. Different specifications of products require different demolding air pressures. However, the existing equipment lacks a flexible air pressure regulation mechanism, making it difficult for the fixed air pressure to adapt to the demolding needs of different products. This structural design deficiency not only limits the applicability of the equipment, but may also cause product deformation or incomplete demolding due to improper air pressure.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a demolding device for rubber products, which has the following features:

[0019] Beneficial effects:

[0020] 1. The demolding device constructs a highly efficient demolding system through the precise coordination of fixed pipes, sealing pipes, connecting chambers, and connecting pipes. The setting of the connecting chambers realizes the uniform distribution of airflow, and the design of the sealing pipes ensures the directional delivery of airflow. This design not only abandons the inefficient traditional manual demolding method, but also realizes automated demolding through the reasonable distribution of airflow, which significantly improves demolding efficiency and ease of operation.

[0021] 2. The one-way device constructs a reliable airflow control system through the synergistic action of the sealing plate, tension spring, and moving frame. The flush design of the sealing plate with the mold core provides good sealing performance, and the design of the tension spring, combined with the sleeve and rod, ensures the reliable reset of the sealing plate. This structure not only effectively prevents the rubber material from blocking the airflow channel through the sealing design of the sealing plate, but also realizes one-way airflow control through the elastic reset mechanism, ensuring the reliability of the demolding operation.

The guiding cooperation between the movable groove and the slide provides a stable motion trajectory, the meshing of gears and racks achieves precise position adjustment, and the threaded connection between the outer sleeve and the inner sleeve ensures the stability of the adjustment. This design not only provides precise air pressure regulation through mechanical transmission, but also ensures the stable use of the adjustment structure through the cooperation of the prism sleeve and prism rod, ensuring the demolding requirements of products of different specifications.

[0032] Please refer to Figures 1-5. A demolding device for rubber products includes a mold core 1. A demolding device is provided inside the mold core 1. The demolding device includes a fixed tube 2, a sealing tube 3, a connecting chamber 4, and a connecting tube 5. The fixed tube 2 and the connecting tube 5 are detachably installed in the mold core 1. The connecting chamber 4 is opened inside the mold core 1. The connecting tube 5 is connected to the bottom of the connecting chamber 4. A one-way device is provided inside the fixed tube 2. The one-way device includes a sealing plate 6, a tension spring 7, and a movable frame 8. The sealing plate 6 is movably disposed inside the sealing tube 3, and the movable frame 8 is installed on the sealing tube 3. Inside the tube 3, the two ends of the tension spring 7 are connected to the sealing plate 6 and the movable frame 8 respectively. An adjustment mechanism is provided inside the mold core 1. The adjustment mechanism includes a movable groove 9, a gear 10, a rack 11, an outer sleeve 12 and an inner sleeve 13. The movable groove 9 is opened inside the mold core 1. The gear 10 is fixedly connected to the outer sleeve 12. The gear 10 and the inner sleeve 13 are rotatably connected to the fixed tube 2 and the sealing tube 3 respectively. The rack 11 is movably arranged in the movable groove 9 and meshes with the gear 10. The inner sleeve 13 is fixedly installed on the outer side of the movable frame 8.

[0033] In this embodiment, when demolding is required, the molded product adheres to the surface of the mold core 1. Then, the gas supply device connected to the connecting pipe 5 is turned on, so that the gas supply device delivers compressed gas to the connecting chamber 4 through the connecting pipe 5. Then, the compressed gas enters each fixed pipe 2 through the connecting chamber 4, and then through the gap between the connecting frame 20 and the fixed pipe 2, and then through the gap between the moving frame 8 and the inner sleeve 13, and then pushes the sealing plate 6, thereby opening the sealing plate 6. This causes the sealing plate 6 to drive the tension spring 7 to stretch, and at the same time, it causes the circular sleeve 19 connected on one side to slide along the circular rod 21, so that the sealing plate 6 pushes the product to perform the demolding operation, so that the product is separated from the mold core 1. When the external gas supply device stops supplying gas, the tension spring 7 pulls the sealing plate 6 to reset, so that the upper end surface of the sealing plate 6 is flush with the upper end surface of the mold core 1.

[0034] Please refer to Figures 1-5 for a further embodiment of the overall equipment: a cylinder 14 is detachably provided on one side of the mold core 1, and a piston rod 15 is connected to the output end of the cylinder 14.

[0035] One end of the piston rod 15 is detachably equipped with a movable frame 16, and multiple racks 11 are fixedly connected to one side of the movable frame 16.

[0036] The movable groove 9 has sliding grooves 17 on both sides, and the rack 11 has slide rails 18 fixed on both sides, with the slide rails 18 sliding in the sliding grooves 17.

[0037] The top of the sealing tube 3 and the upper surface of the sealing plate 6 are flush with the upper surface of the mold core 1.

[0038] A circular sleeve 19 is fixedly connected to one side of the sealing plate 6, a connecting frame 20 is fixedly installed inside the fixing tube 2, a circular rod 21 is fixedly installed on one side of the connecting frame 20, and the circular sleeve 19 is slidably sleeved on the outside of the circular rod 21.

[0039] The inner side of the movable frame 8 is fixedly connected with a prism sleeve 22, and the side of the connecting frame 20 is fixedly provided with a prism rod 23. The prism sleeve 22 is slidably sleeved on the outside of the prism rod 23.

[0040] The outer wall of the inner sleeve 13 is movably connected to the inner wall of the outer sleeve 12 via threads.

[0041] More specifically, when the opening pressure needs to be adjusted according to process requirements, firstly, the cylinder 14 is opened synchronously, so that the piston rod 15 connected to the output end of the cylinder 14 pushes the movable frame 16 to move in the movable groove 9. Then, the movable frame 16 drives multiple racks 11 to move synchronously, so that the racks 11 drive the slide rails 18 on both sides to slide along the slide groove 17. Then, the racks 11 drive the gears 10 meshing with them to rotate synchronously in the forward direction. Then, the gears 10 drive the inner sleeve 12 connected to the inner side to rotate synchronously. Since the outer wall of the inner sleeve 13 is movably connected to the inner wall of the outer sleeve 12 through threads, and the prism rod 23 and prism sleeve 22 cooperate to limit the movable frame 8, the movable frame 8 and the inner sleeve 13 will not rotate. Then, the inner sleeve 13 will drive the movable frame 8 and the prism sleeve 22 to slide downward along the prism rod 23, so that the movable frame 8 drives the tension spring 7 to stretch, thereby increasing the distance between the movable frame 8 and the sealing plate 6, increasing the force applied by the tension spring 7, so that a greater pressure is required to open the sealing plate 6. After the adjustment is appropriate, the cylinder 14 can be closed.

[0042] In summary, during the use or operation of the overall equipment: when demolding is required, the molded product adheres to the surface of the mold core 1. Then, the gas supply device connected to the connecting pipe 5 is turned on, allowing the gas supply device to deliver compressed gas through the connecting pipe 5 to the connecting chamber 4. The compressed gas then enters each fixed pipe 2 through the connecting chamber 4, and then through the gap between the connecting frame 20 and the fixed pipe 2, and through the gap between the moving frame 8 and the inner sleeve 13, and then pushes the sealing plate 6, thereby opening the sealing plate 6. This causes the sealing plate 6 to drive the tension spring 7 to stretch, and at the same time, it causes the circular sleeve 19 connected on one side to slide along the circular rod 21, so that the sealing plate 6 pushes the product to perform the demolding operation, allowing the product to detach from the mold core 1. When the external gas supply device stops supplying gas, the tension spring 7 pulls the sealing plate 6 to reset, so that the upper surface of the sealing plate 6 is flush with the upper surface of the mold core 1.

[0043] When the opening pressure needs to be adjusted according to process requirements, firstly, the cylinder 14 is opened synchronously, so that the piston rod 15 connected to the output end of the cylinder 14 pushes the movable frame 16 to move in the movable groove 9. Then, the movable frame 16 drives multiple racks 11 to move synchronously, so that the racks 11 drive the slide rails 18 on both sides to slide along the slide groove 17. Then, the racks 11 drive the gears 10 meshing with them to rotate synchronously in the forward direction. Then, the gears 10 drive the inner sleeve 12 connected to the inner side to rotate synchronously. Since the outer wall of the inner sleeve 13 is movably connected to the inner wall of the outer sleeve 12 through threads, and the prism rod 23 and prism sleeve 22 cooperate to limit the movable frame 8, the movable frame 8 and the inner sleeve 13 will not rotate. Then, the inner sleeve 13 will drive the movable frame 8 and the prism sleeve 22 to slide downward along the prism rod 23, so that the movable frame 8 drives the tension spring 7 to stretch, thereby increasing the distance between the movable frame 8 and the sealing plate 6, increasing the force applied by the tension spring 7, so that a greater pressure is required to open the sealing plate 6. After the adjustment is appropriate, the cylinder 14 can be closed.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
