Description

Technical Field

[0001] This utility model relates to the field of high-temperature vulcanization molding of silicone rubber, specifically a high-temperature vulcanization molding device for silicone rubber. Background Technology

[0002] High-temperature vulcanization molding of silicone rubber is a key process in the preparation of silicone rubber products. It uses high temperature and high pressure to vulcanize and shape the silicone material.

[0003] Traditional molding equipment typically uses manual operation of the lower pressure plate for opening, closing, and demolding. After vulcanization, manual cleaning with tools such as air guns is required to remove the silicone rubber adhering to the mold or lower pressure plate surface. This process is inefficient and poses a risk of burns in high-temperature environments. Furthermore, if personnel remain in the operating area when the lower pressure plate closes the mold under high pressure, it may cause mechanical pinching accidents. Existing equipment generally lacks active safety protection mechanisms.

[0004] Therefore, a high-temperature vulcanization molding device for silicone rubber is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, manual cleaning of silicone rubber products adhering to the surface of molds or pressure plates using tools such as air guns is inefficient and poses a risk of burns in high-temperature environments; personnel lingering in such environments may lead to mechanical pinching accidents. This utility model proposes a high-temperature vulcanization molding device for silicone rubber.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the silicone rubber high temperature vulcanization molding device of this utility model includes a molding machine, a flip-down pressure plate is provided on the side of the molding machine, a moving component is fixedly connected to both sides of the pressure plate, a scraper is fixedly connected to the side of the moving component, and an alarm component is fixedly connected to the top surface of the pressure plate.

[0007] The moving component includes slide grooves fixedly connected to both sides of the lower pressure plate, a slider slidably connected inside the slide groove, a lead screw threadedly connected inside the slider, the top end of the lead screw fixedly connected to the output end of the drive motor, and the drive motor fixedly connected to the top end of the slide groove.

[0008] The alarm assembly includes a device box fixedly connected to the top surface of the lower pressure plate, an image acquisition structure fixedly connected to the side of the device box, a control board sleeved inside the device box, and an alarm fixedly connected to the top surface of the device box.

[0009] Preferably, the bottom end of the slide groove is provided with a limiting end coaxial with the lead screw, and the drive motor drives the slider to move up and down along the slide groove through the lead screw and drives the scraper to slide against the surface of the lower pressure plate.

[0010] Preferably, the control board is electrically connected to the image acquisition structure and the alarm, and is configured to trigger the alarm and prevent the lower platen of the molding machine from pressing down when the image acquisition structure detects that the personnel have not left.

[0011] Preferably, the control board is also electrically connected to the drive motor to control the start of the drive motor after high-temperature vulcanization is completed, so that the scraper moves along the surface of the lower pressure plate to scrape off the adhered silicone rubber product.

[0012] Preferably, the image acquisition structure is an infrared camera, whose detection direction covers the operating area in front of the pressure plate.

[0013] Preferably, a hydraulic drive mechanism is provided between the flipping shaft of the lower pressure plate and the forming machine, and the control board of the alarm component integrates a distance detection algorithm to lock the hydraulic drive mechanism when the distance between the personnel and the lower pressure plate is less than a preset safe distance.

[0014] The advantages of this utility model are:

[0015] 1. This utility model sets up moving components on both sides of the lower pressure plate, and uses the linkage structure of sliding groove, slider, lead screw and drive motor to drive the scraper to slide along the surface of the lower pressure plate, automatically scraping off the silicone rubber products that adhere after high temperature vulcanization, replacing the traditional manual air gun cleaning method, significantly improving demolding efficiency and avoiding the risk of burns caused by operators coming into contact with high temperature parts.

[0016] 2. This utility model integrates an alarm component on the top surface of the lower pressure plate. The image acquisition structure monitors the status of personnel in the operating area in front of the lower pressure plate in real time. When it detects that personnel have not left, the control board triggers an alarm to issue a warning and prevent the lower pressure plate from pressing down. At the same time, the integrated distance detection algorithm locks the hydraulic drive mechanism. This dual protection mechanism effectively eliminates the risk of mechanical pinching accidents and improves the safety of equipment operation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a high-temperature vulcanization molding device for silicone rubber includes a molding machine 1. A flip-up lower pressure plate 5 is provided on the side of the molding machine 1. Movable components 2 are fixedly connected to both sides of the lower pressure plate 5. Scrapers 3 are fixedly connected to the side of the movable components 2. An alarm component 4 is fixedly connected to the top surface of the lower pressure plate 5. The movable components 2 include slide grooves 21 fixedly connected to both sides of the lower pressure plate 5. A slider 22 is slidably connected inside the slide groove 21. A lead screw 23 is threadedly connected inside the slider 22. The top end of the lead screw 23 is fixedly connected to the output end of a drive motor 24. The drive motor 24 is fixedly connected to the top end of the slide groove 21.

[0025] During operation, the slide groove 21 of the moving component 2 is fixed to both sides of the lower pressure plate 5. The lead screw 23 in the slide groove 21 is driven to rotate by the drive motor 24, which drives the threaded slider 22 to slide up and down along the slide groove 21. When the slider 22 moves, it pushes the scraper 3 to move laterally against the surface of the lower pressure plate 5. After the high-temperature vulcanization is completed, the control board 43 sends a start signal to the drive motor 24. The drive motor 24 drives the lead screw 23 to rotate, so that the slider 22 moves from the top end to the bottom end of the slide groove 21. During the movement, the scraper 3 scrapes off the silicone rubber product adhering to the surface of the lower pressure plate 5. The limiting end at the bottom of the slide groove 21 restricts the stroke of the slider 22 to avoid derailment. After demolding is completed, the drive motor 24 reverses to reset the scraper 3.

[0026] Furthermore, the alarm component 4 includes a device box 41 fixedly connected to the top surface of the lower pressure plate 5, an image acquisition structure 42 fixedly connected to the side of the device box 41, a control board 43 sleeved inside the device box 41, and an alarm 44 fixedly connected to the top surface of the device box 41.

[0027] During operation, the image acquisition structure 42 of the alarm component 4 is an infrared camera, which is installed on the side of the equipment box 41 and faces the operating area. The control board 43 captures images of the operating area in real time through the image acquisition structure 42 and analyzes the distance between the personnel and the lower pressure plate 5 based on the distance detection algorithm. When the personnel are detected to be within the preset safe distance, the control board 43 triggers the alarm 44 to issue an audible and visual warning, and at the same time sends a locking signal to the molding machine 1 to prevent the lower pressure plate 5 from pressing down. It also locks the flipping shaft of the lower pressure plate 5 by cutting off the power supply of the hydraulic drive mechanism until the image acquisition structure 42 confirms that there are no personnel left in the operating area, then releases the lock and resumes the action of the lower pressure plate 5.

[0028] Furthermore, the image acquisition structure 42 is an infrared camera, whose detection direction covers the operating area in front of the pressure plate 5;

[0029] During operation, the image acquisition structure 42 uses an infrared camera fixed to the side of the equipment box 41. Its detection direction covers the operating area in front of the lower pressure plate 5. The infrared camera monitors personnel activities in the operating area in real time through thermal imaging technology. The control board 43 receives the image data acquired by the infrared camera and analyzes the personnel position. When a person is detected within the closed path of the lower pressure plate 5, the control board 43 immediately triggers the alarm 44 (Patlite P2-7112A) to issue an audible and visual alarm, and simultaneously sends a stop signal to the molding machine 1 to prevent the lower pressure plate 5 from pressing down. This implementation method enables stable monitoring in high-temperature environments through the image acquisition structure 42, avoiding misjudgments caused by thermal radiation interference from traditional optical cameras. Combined with the rapid response mechanism of the control board 43, it ensures that equipment operation is interrupted in time when personnel approach dangerous areas, significantly reducing the risk of mechanical pinching injuries.

[0030] Furthermore, a hydraulic drive mechanism is provided between the flipping shaft of the lower pressure plate 5 and the forming machine 1. The control board 43 of the alarm component 4 integrates a distance detection algorithm, which locks the hydraulic drive mechanism when the distance between the personnel and the lower pressure plate 5 is less than the preset safe distance.

[0031] During operation, the flipping shaft of the lower pressure plate 5 is connected to the forming machine 1 via a hydraulic drive mechanism for flipping control. The control board 43 integrates a distance detection algorithm, which dynamically calculates the distance between the person and the lower pressure plate 5 based on real-time data acquired by the image acquisition structure 42 of the Honeywell HIS-T1220D infrared thermal imaging camera. When the algorithm determines that the distance between the person and the lower pressure plate 5 is less than a preset safety threshold, the control board 43, which is an Advantech UNO-2484G industrial embedded control motherboard, sends a locking command to the hydraulic drive mechanism, cuts off the hydraulic oil circuit, and locks the flipping shaft, forcing the lower pressure plate 5 to remain stationary until the danger is eliminated. This implementation method, through the dual protection of the physical locking mechanism of the lower pressure plate 5 flipping shaft connection and the distance detection algorithm, accurately prevents abnormal movements of the lower pressure plate 5 when a person approaches, avoids crushing accidents caused by human error or equipment failure, and improves the safety redundancy of the equipment under complex working conditions.

[0032] Working Principle: In the working process of the high-temperature vulcanization molding device for silicone rubber, the silicone rubber raw material is first placed in the mold of the molding machine 1. The flip-up lower pressure plate 5 closes through the hydraulic drive mechanism and applies high pressure to the mold, completing the vulcanization and shaping in a high-temperature environment. After vulcanization, the lower pressure plate 5 automatically flips open. At this time, the control board 43 sends a start command to the drive motor 24 of the moving component 2. The drive motor 24 drives the lead screw 23 to rotate, causing the slider 22 to move from the top to the bottom along the slide groove 21, driving the scraper 3 to slide closely against the surface of the lower pressure plate 5, scraping off the adhered silicone rubber product and completing the automatic demolding. At the same time, the image acquisition structure 42 of the alarm component 4 monitors the operating area in front of the lower pressure plate 5 in real time through an infrared camera. When personnel are detected entering the preset safe distance range, the control board 43 immediately triggers the alarm 44 to issue an audible and visual warning, and locks the hydraulic drive mechanism through the distance detection algorithm, forcing the lower pressure plate 5 to remain stationary until the personnel leave the danger area and the equipment resumes operation, realizing the fully automated control of vulcanization, demolding and safety protection.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
