Description

Technical Field

[0001] This utility model relates to the field of conductive silicone rubber vulcanization technology, and in particular to a conductive silicone rubber connector molding and vulcanization device. Background Technology

[0002] In the production of conductive silicone rubber connectors, vulcanization is a critical process, but existing vulcanization equipment has several technical shortcomings, making it difficult to meet the demands for efficient and precise production. The pressing and flipping operation is inconvenient: Traditional pressing structures are mostly bolt-fixed or bearingless hard contact flipping designs, which have high resistance when flipping and require tools or a large force to open and close. In batch operations, the manual labor intensity is high and the efficiency is low. Moreover, the base placement area is not fully exposed after opening and closing, making it difficult to observe the placement position of the silicone rubber plate. It is easy to cause vulcanization quality problems due to misalignment, and residual impurities are also difficult to clean.

[0003] The range of applications is limited. Currently, most of them set the overall placement plate to a constant thickness. When the vulcanization operation of rubber plates with different thicknesses and sizes is required, it is necessary to switch the overall placement clamping plate for auxiliary operation, which increases the cost and makes disassembly and replacement cumbersome and inefficient. Therefore, a conductive silicone rubber connector molding and vulcanization device is needed. Utility Model Content

[0004] Based on the existing technical problems, this utility model proposes a molding and vulcanization device for conductive silicone rubber connectors.

The pressing and flipping mechanism enables the opening and closing or pressing and closing action when the conductive silicone rubber plate is placed. The adjustment and positioning mechanism enables quick replacement to accommodate the vulcanization of conductive silicone rubber sheets of different thicknesses.

[0006] Preferably, the pressing and flipping mechanism includes a pressing and flipping plate, a U-shaped tie rod is fixedly installed at the front end of the pressing and flipping plate, and a transfer groove is opened at the top of the rear end of the vulcanization molding base. The inner sidewalls at both ends of the transfer groove are rotatably connected to a flipping shaft through bearings, and the arc surface of the flipping shaft is fixedly installed with the surface of the pressing and flipping plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-5 A conductive silicone rubber connector molding and vulcanization device includes a vulcanizing machine body 1, a vulcanizing molding base 2 installed above the placement platform of the vulcanizing machine body 1, and an adjustment and positioning mechanism 3 and a pressing and flipping mechanism 4 respectively provided on the top of the vulcanizing molding base 2.

[0020] The pressing and flipping mechanism 4 enables the opening and closing or pressing and closing action when the conductive silicone rubber sheet is placed. The pressing and flipping mechanism 4 includes a pressing and flipping plate 41, a U-shaped tie rod 42 is fixedly installed at the front end of the pressing and flipping plate 41, and an adapter groove 43 is opened at the top of the rear end of the vulcanization molding base 2. The inner sidewalls at both ends of the adapter groove 43 are rotatably connected to the flipping shaft 44 through bearings. The arc surface of the flipping shaft 44 is fixedly installed with the surface of the pressing and flipping plate 41.

[0021] Specifically, the pressing and flipping plate 41 is connected to the transfer groove 43 bearing of the vulcanization molding base 2 via the flipping shaft 44. The rolling friction characteristics of the bearing significantly reduce the resistance during flipping. Compared to the bearingless "hard contact rotation" structure, the operator does not need to overcome a large sliding friction force when pushing the pressing and flipping plate 41, and can easily achieve the "opening and closing" or "pressing and closing" action. Especially for batch vulcanization operations, each conductive silicone rubber sheet needs to be flipped once for placement and removal. This design can significantly reduce the intensity of manual operation and improve the efficiency of a single operation.

[0022] The U-shaped pull rod 42 fixed at the front end of the pressing and flipping plate 41 provides the operator with a clear and comfortable point of force application: on the one hand, the U-shaped structure is suitable for the hand grip posture, avoiding the problem of slipping and discomfort of the traditional "straight rod pull rod"; on the other hand, the pull rod is set at the front end away from the flipping shaft 44, which conforms to the lever principle. The operator can drive the pressing and flipping plate 41 to flip by applying a small force through the pull rod with the flipping shaft 44 as the fulcrum, further reducing the operation threshold and allowing even novices to quickly master the opening and closing operation.

[0023] The pressing and flipping plate 41 achieves the action of "flipping and opening" through the flipping shaft 44. When opening and closing, the placement area of ​​the vulcanizing molding base 2 can be fully exposed. Operators can intuitively observe whether the placement position of the silicone rubber plate is correct. It is also convenient to clean the residual impurities such as silicone rubber debris on the surface of the base after vulcanization, so as to avoid impurities affecting the subsequent vulcanization quality and improve the visibility and maintainability of the operation process.

[0024] The middle surface of both rear sides of the pressing and flipping plate 41 is set in an arc shape, and the rear sides of the vulcanizing base 2 are also set in an arc shape. The arc surface of the rear end of the pressing and flipping plate 41 is in contact with the arc surface of the rear end of the vulcanizing base 2.

[0025] Specifically, during the opening and closing or pressing and closing action of the pressing and turning plate 41 as it rotates around the turning axis 44, if the contact points between the two are right angles or planar structures, problems such as "corner collision" or "face-to-face hard friction" are likely to occur during the turning process, causing the turning action to stall, and even requiring the operator to apply additional force to push it. However, the design of the arc surface allows for a sliding fit between the two surfaces when they come into contact; the contact point changes dynamically with the turning angle, avoiding the concentration of resistance caused by friction at fixed points; the arc transition has no sharp corners, and there will be no "jamming" or "stuttering" phenomenon, ensuring that the pressing and turning plate 41 moves smoothly from "fully open" to "fully pressed", reducing the intensity of manual operation, and is especially suitable for the high-frequency turning operation requirements in batch vulcanization operations.

[0026] The matching of the arc surface ensures that when the pressing and flipping plate 41 is closed, it can only adhere along the fixed arc trajectory and cannot shift to the sides. This ensures that the lower surface of the pressing and flipping plate 41 is precisely aligned with the conductive silicone rubber plate on the vulcanization molding base 2, avoiding quality problems such as uneven vulcanization and thickness deviation at the edge of the silicone rubber plate due to offset.

[0027] The adjustment and positioning mechanism 3 enables quick replacement to accommodate the placement and vulcanization of conductive silicone rubber sheets of different thicknesses. The adjustment and positioning mechanism 3 includes a transverse insertion groove 31 and a longitudinal insertion groove 32 formed on the top of the vulcanization molding base 2, with multiple transverse insertion grooves 31 and multiple longitudinal insertion grooves 32 arranged in a crisscross pattern.

[0028] Specifically, the transverse insertion groove 31 extends laterally along the vulcanization molding base 2, and the longitudinal insertion groove 32 extends longitudinally. The intersecting grooves form a two-dimensional positioning grid of "transverse + longitudinal". When the transverse positioning insertion rod 33 and the longitudinal positioning insertion rod 34 are inserted into the corresponding grooves, the two sets of insertion rods can limit the conductive silicone rubber sheet from different directions: the transverse insertion rod restricts the longitudinal sliding displacement of the silicone rubber sheet, and the longitudinal insertion rod restricts its transverse sliding displacement. The two work together to fix the silicone rubber sheet in the preset vulcanization area, avoiding the silicone rubber sheet from shifting due to slight vibration or pressure of the device during the vulcanization process, and ensuring that the dimensional accuracy of the product after vulcanization meets the requirements.

[0029] The cross arrangement of the horizontal and vertical insertion slots 32 not only allows for the adaptation of silicone rubber sheets of different thicknesses by replacing insertion rods of different specifications, but also allows for the adaptation of silicone rubber sheets of different lengths and widths by adjusting the insertion position of the insertion rods in the cross slots. For example, for small-sized silicone rubber sheets, the insertion rods can be inserted into the horizontal and vertical slots in the middle of the base; for large-sized silicone rubber sheets, the insertion rods can be inserted into the slots in the edge area without replacing the entire vulcanization base 2. This significantly expands the adaptability range of the device to silicone rubber sheet specifications and reduces the cost for enterprises to configure dedicated vulcanization devices for products of different specifications.

[0030] A transverse positioning rod 33 is slidably inserted into the inner wall of the transverse insertion slot 31, and a longitudinal positioning rod 34 is slidably inserted into the inner wall of the longitudinal insertion slot 32. The multiple longitudinal positioning rods 34 are all located between two transverse positioning rods 33.

[0031] Specifically, the transverse / longitudinal positioning connectors 34 are all engaged with the corresponding grooves via a "sliding insertion" method, without complex locking structures. Operators only need to apply pushing or pulling force along the axial direction of the groove to insert or remove the connectors. This design perfectly complements the core function of the adjusting positioning mechanism 3: "quick replacement to accommodate silicone rubber sheets of different thicknesses." When switching silicone rubber sheet thicknesses, there is no need to disassemble screws, clips, or other components; only the corresponding connector needs to be quickly replaced, significantly reducing replacement time and improving the overall efficiency of the vulcanization operation.

[0032] The multiple transverse positioning plug rods 33 and the multiple longitudinal positioning plug rods 34 are all configured with various thickness specifications, each of which is larger than the previous thickness specification, and the thickness is ≥1mm.

[0033] Specifically, in the vulcanization production of conductive silicone rubber, different product models often require silicone rubber sheets of different thicknesses, such as standard thicknesses like 1mm, 2mm, and 3mm, or even customized thicknesses. The connector is designed with "multiple thickness specifications, with each subsequent specification larger than the previous one." By replacing the connector with a different thickness, a suitable positioning reference can be provided for silicone rubber sheets of varying thicknesses. For example, when vulcanizing a 1mm thick silicone rubber sheet, a 1mm thick connector is used, its top flush with the upper surface of the sheet or providing slight restraint; when vulcanizing a 3mm thick sheet, a 3mm thick connector is used to ensure the restraint height matches the sheet thickness. This eliminates the need for separate vulcanization devices or positioning components for different thicknesses, significantly reducing equipment investment costs and achieving a one-stop vulcanization operation that "one device adapts to multiple thicknesses."

[0034] Positioning holes 35 are provided at the bottom of multiple transverse positioning plug rods 33 and multiple longitudinal positioning plug rods 34. Clamping holes 36 are provided on the inner bottom wall of transverse plug groove 31 and the inner bottom wall of longitudinal plug groove 32. A ball plunger 37 is threadedly connected to the inner wall of the clamping hole 36. The ball head surface of the ball plunger 37 is slidably inserted into the inner wall of the positioning hole 35.

[0035] Specifically, the core feature of the ball-head plunger 37 is that the ball head can elastically extend and retract within the plunger body: when the positioning insertion rod is inserted laterally / longitudinally into the corresponding insertion slot, the bottom of the insertion rod gradually approaches the ball-head plunger 37 in the clamping hole 36, and the ball head retracts into the plunger body after being squeezed by the bottom of the insertion rod; when the positioning hole 35 at the bottom of the insertion rod is aligned with the position of the ball-head plunger 37, the ball head pops out under the action of the spring inside the plunger and slides into the inner wall of the positioning hole 35, forming an "elastic engagement" structure. This design can automatically fix the insertion rod in the preset position, avoiding the insertion rod from sliding along the groove due to device vibration and pressure force transmission during the vulcanization process, ensuring the stability of the limiting boundary of the insertion rod on the conductive silicone rubber plate, and fundamentally preventing the silicone rubber plate from shifting and vulcanization size deviation caused by the loosening of the insertion rod.

[0036] This practical and efficient system is easy to operate: the pressing and flipping mechanism 4 is connected to the flipping shaft 44 through the bearing to reduce the flipping resistance. With the help of the front U-shaped pull rod 42, the operator can easily complete the opening and closing, reducing the intensity and improving the efficiency in batch operations. When opening and closing, the base placement area is exposed, which makes it easy to observe the position of the silicone rubber plate and clean impurities, ensuring the quality of subsequent vulcanization.

[0037] Precise and stable positioning: The horizontal and vertical interlocking slots of the adjustment positioning mechanism 3 form a two-dimensional grid, and the longitudinal rod of the sliding positioning rod is located between the two horizontal rods to achieve omnidirectional positioning of the silicone rubber sheet; the ball plunger 37 and the positioning hole 35 of the insertion rod are elastically engaged to prevent the insertion rod from loosening, ensure that the plate does not shift during vulcanization, and guarantee the dimensional accuracy of the product.

[0038] Wide range of compatibility: The positioning plug rod is available in various gradient thickness specifications ≥1mm, which can match silicone rubber sheets of different thicknesses; by adjusting the position of the plug rod in the cross groove, it can adapt to different length and width plates without the need to replace the base or special devices, reducing the equipment investment cost of enterprises and realizing one-stop vulcanization operation.

[0039] Durable and easy to maintain: The pressing and flipping plate 41 fits with the arc surface at the rear end of the base to avoid flipping jamming and wear; the ball plunger 37 is a standardized component with an elastic locking design to reduce wear on the plug rod and slot, and it is easy to replace individually after damage, reducing maintenance costs and downtime.

[0040] Working principle: Preliminary preparation and positioning adjustment: According to the thickness of the conductive silicone rubber sheet to be vulcanized, select the corresponding specification of the horizontal / vertical positioning plug rod 34 and slide it into the horizontal / vertical plug groove 32; during the insertion process, the bottom of the plug rod squeezes the ball head plunger 37 to retract the ball head. When the positioning hole 35 is aligned with the ball head, the ball head pops out and engages, completing the fixing of the plug rod and forming a two-dimensional positioning frame that adapts to the size of the sheet.

[0041] Plate placement and pressing: Hold the U-shaped pull rod 42 at the front end of the pressing and flipping plate 41, and flip it upward with the bearing connection between the flipping shaft 44 and the adapter groove 43 as the fulcrum to expose the base placement area and place the conductive silicone rubber plate into the positioning frame; then flip the pressing and flipping plate 41 downward, and slide its rear arc surface against the rear arc surface of the base until it is fully pressed and the plate is fixed.

[0042] Vulcanization operation and subsequent operations: Start the vulcanizing machine body 1 to vulcanize the silicone rubber sheet on the base; after vulcanization is completed, pull the U-shaped pull rod 42 again to flip and press the flip plate 41, take out the finished product, clean the residual impurities on the base, and replace the corresponding specification plug rod before proceeding with the vulcanization operation of the next batch of silicone rubber sheets of different specifications.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
