Description

Technical Field

[0001] This utility model relates to the field of silicone production and processing technology, and in particular to a silicone production packaging positioning and anti-displacement tooling. Background Technology

[0002] In the fields of electronics and medical, silicone is often used as a protective material. The encapsulation process can completely wrap the internal circuit boards, chips, wires and other components, and isolate them from external water, dust, impurities and mechanical impact. When silicone is produced and encapsulated, it is often necessary to align it precisely with other components such as electronic pins and metal interfaces. In order to improve the encapsulation accuracy, tooling is required. Tooling fixes the position of the silicone raw material or the component to be encapsulated, and avoids the displacement caused by pressure and temperature during the vulcanization process. For example, in the silicone encapsulation of sensors, it can ensure the concentricity of the pins and the silicone shell, so that subsequent assembly will not be jammed. For example, patent CN221447112U discloses a packaging fixture, including: a base and a positioning block; the base has a bearing surface for placing the object to be packaged, and the bearing surface has a positioning part; the positioning block is movably disposed on the base, and when the positioning block is in the positioning position, the positioning block and the positioning part are respectively used to position the edges of each packaging unit in the object to be packaged. This packaging fixture, through the cooperation of the positioning block and the positioning part, can position each packaging unit in the object to be packaged, thereby ensuring the positional accuracy of each packaging unit and improving the overall packaging accuracy; Although the aforementioned packaging fixture can position each individual packaged unit in the package body through the cooperation of the positioning block and the positioning part, thereby ensuring the positional accuracy of each packaged unit and improving the overall packaging accuracy, after a silicone packaging and curing operation, the user still needs to manually pull out the products one by one. This process is not only inconvenient for demolding due to product adhesion, but also prone to damage to the packaged products due to silicone adhesion. Therefore, it is necessary to design a silicone production packaging positioning anti-offset fixture. Utility Model Content

[0003] The purpose of this invention is to provide a silicone production packaging positioning and anti-offset tooling to solve the defect of existing packaging tooling that makes it difficult to quickly and minimally damage the molded product after the silicone and component packaging process is completed.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a silicone production packaging positioning anti-offset tooling, including a base; Both ends of the base are equipped with demolding drive mechanisms, and the demolding drive mechanism includes a housing fixed to one side of the base. Inside the housing, a worm and a worm wheel are movably connected in sequence, and a lead screw is fixed at the middle position of the worm wheel. The first slider and the second slider are symmetrically mounted on both sides of the lead screw, and a lower assembly seat is fixed on both the first slider and the second slider. The lower assembly seat is uniformly fitted with a lower tooling mold, and a heat dissipation base plate for packaging that matches the lower tooling mold is fixed at the bottom of the base. Both ends of the base are equipped with telescopic cylinders, and the output end of the telescopic cylinder is connected to the upper assembly seat. The upper tooling mold is evenly installed on the upper assembly seat. The heat dissipation base plate for packaging is internally equipped with serpentine water-cooling pipes, and both sides of the heat dissipation base plate for packaging are provided with threaded water guide ports that are connected to the serpentine water-cooling pipes.

[0005] Furthermore, the worm and worm wheel are movably connected to the inner wall of the housing via bearings, and a motor is mounted on the top of the worm.

[0006] Furthermore, both the first and second sliders are hollow structures, and the inner walls of the first and second sliders are provided with internal thread layers in opposite directions. The outer wall of the lead screw is provided with an external thread layer that matches the internal thread layer. The base is provided with guide grooves that match the first and second sliders.

[0007] Furthermore, the upper tooling mold and the lower tooling mold are arranged at equal intervals on the upper assembly base and the lower assembly base, respectively, and there are 7 upper tooling molds.

[0008] Furthermore, limit sleeves are fixed at all four corners of the upper assembly seat, and a vertical limit rod matching the limit sleeves is fixed at the top of the base.

[0009] Furthermore, the top of the upper tooling mold is provided with an external threaded pipe that is threadedly connected to the upper assembly seat, and the external threaded pipe extends vertically through and to the top of the upper assembly seat.

[0010] Furthermore, one side of the lower tooling mold is fixed with an assembly pin that engages with the lower assembly seat, and the interior of the assembly pin is slidably connected to an elastic locking block via a spring.

[0011] Furthermore, the lower assembly seat is provided with a disassembly pre-drilled hole that matches the elastic locking block.

[0012] The advantages of the silicone production packaging positioning and anti-offset tooling provided by this utility model are: By installing a demolding drive mechanism, and using a batch of upper and lower tooling molds combined with a heat dissipation base plate for packaging to form a closed packaging cavity, a rigid constraint can be formed on the silicone liquid, which is conducive to achieving batch positioning packaging. Furthermore, through the transmission action of the worm gear and worm wheel, and the matching effect of the symmetrically distributed first and second sliders and lead screw, the lower tooling molds arranged at equal intervals on the two lower combination seats can be driven to close or separate. Physical separation replaces traditional manual peeling, avoiding damage to the silicone product caused by external force pulling. Furthermore, the heat generated by the silicone vulcanization in the tooling mold cavity is transferred to the heat dissipation base plate for packaging. The serpentine water cooling pipes in the heat dissipation base plate for packaging are connected to cooling water through the threaded water guides on both sides. The heat is quickly removed by the circulation of cooling water, ensuring uniform vulcanization and packaging of silicone. By incorporating assembly pins, the components to be packaged can be sequentially mounted into the cavities of the lower tooling mold, which is installed at equal intervals on the lower assembly base. This allows for initial batch positioning of multiple components. Furthermore, the lower tooling mold is engaged with the lower assembly base via the assembly pins. The elastic locking blocks within the assembly pins pop out under the action of springs and engage with the slots of the lower assembly base for quick fixation. If the mold structure needs to be changed according to the requirements of the packaged product, it can be unlocked and replaced by disassembling the pre-drilled holes and pressing the elastic locking blocks. Additionally, the threaded connection between the external threaded tube and the upper assembly base can be used to replace the upper tooling mold that matches the lower tooling mold.

[0015] 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 protection scope of the present utility model.

[0016] Please see Figures 1-5 The silicone production packaging positioning and anti-offset tooling provided by this utility model includes a base 1.

[0017] Reference Figures 1-3 Both ends of the base 1 are equipped with demolding drive mechanisms 3, and the demolding drive mechanism 3 includes a housing 301 fixed to one side of the base 1. The housing 301 is movably connected to a worm gear 302 and a worm wheel 303 in sequence. A lead screw 304 is fixed at the middle position of the worm wheel 303. The first slider 305 and the second slider 306 are symmetrically mounted on both sides of the lead screw 304, and a lower assembly seat 4 is fixed on both the first slider 305 and the second slider 306. The lower assembly seat 4 is uniformly fitted with a lower tooling mold 6, and a heat dissipation base plate 12 for packaging that matches the lower tooling mold 6 is fixed at the bottom of the base 1. Telescopic cylinders 7 are installed at both ends of the base 1, and the output end of the telescopic cylinders 7 is connected to the upper assembly seat 11. Upper tooling molds 10 are evenly installed on the upper assembly seat 11. The heat dissipation base plate 12 for packaging is provided with a serpentine water cooling pipe 14 inside, and both sides of the heat dissipation base plate 12 for packaging are provided with threaded water guide ports 13 that are connected to the serpentine water cooling pipe 14. The worm 302 and the worm wheel 303 are movably connected to the inner wall of the housing 301 via bearings, and a motor 307 is installed on the top of the worm 302; Both the first slider 305 and the second slider 306 are hollow structures, and the inner sidewalls of the first slider 305 and the second slider 306 are provided with internal thread layers in opposite directions. The outer sidewall of the lead screw 304 is provided with an external thread layer that matches the internal thread layer. The base 1 is provided with a guide groove 2 that matches the first slider 305 and the second slider 306.

[0018] An external power supply is used to pre-position the components to be packaged into the cavities of the lower tooling molds 6, which are arranged at equal intervals on the lower assembly base 4. This completes the initial batch positioning of multiple components. Then, the telescopic cylinder 7 is activated to push the upper assembly base 11 downward. The limiting sleeve 9 of the upper assembly base 11 slides along the vertical limiting slide rod 8 of the base 1, ensuring that the upper assembly base 11 descends vertically and avoids lateral displacement. This facilitates the accurate alignment of the upper tooling mold 10 on the upper assembly base 11 with the lower tooling mold 6 of the lower assembly base 4. The upper tooling mold 10 and the lower tooling mold 6 close to form a closed cavity. Finally, silicone liquid for packaging the components is introduced through the external threaded tube 15, allowing it to flow into the closed packaging cavity formed by the closure of the upper tooling mold 10 and the lower tooling mold 6. The closed cavity provides rigid constraint to the silicone liquid. Even if the silicone liquid flows slightly before vulcanization, it will be restricted by the cavity contour, ensuring that the final molded dimensions are consistent with the design. In addition to the role of batch positioning and packaging, during the demolding operation, the motor 307 is started, driving the worm gear 302 to rotate. The worm gear 302 meshes with the worm wheel 303, driving the lead screw 304 in the middle of the worm wheel 303 to rotate synchronously. At this time, since the inner walls of the first slider 305 and the second slider 306 have internal threads with opposite directions and match the external threads of the lead screw 304, when the lead screw 304 rotates, the two sliders move synchronously towards or away from each other along the guide groove 2 of the base 1. This drives the lower tooling molds 6, which are equally spaced on the two lower combination seats 4, to close or separate, ensuring that they are aligned with the upper tooling mold 10 when closed, thus achieving anti-offset positioning. It also enables the rapid demolding of the packaged silicone products by automatically separating the two corresponding lower tooling molds 6. Physical separation replaces traditional manual peeling, avoiding damage to the silicone products caused by external force pulling, and reducing the damage to product precision caused by manual contact.

[0019] During use, the heat generated by the vulcanization of silicone in the tooling mold cavity during the encapsulation process is transferred to the heat dissipation base plate 12 for encapsulation. The serpentine water cooling pipe 14 in the heat dissipation base plate 12 is connected to the cooling water through the threaded water guides 13 on both sides. The heat is quickly carried away by the circulation of the cooling water, ensuring uniform vulcanization of silicone and stable performance.

[0020] Reference Figures 4-5 The upper tooling mold 10 and the lower tooling mold 6 are arranged at equal intervals on the upper assembly base 11 and the lower assembly base 4, respectively, and there are 7 upper tooling molds 10. Limiting sleeves 9 are fixed at the four corners of the upper assembly seat 11, and a vertical limiting slide bar 8 that matches the limiting sleeves 9 is fixed at the top of the base 1. The top of the upper tooling mold 10 is provided with an external threaded tube 15 that is threadedly connected to the upper assembly seat 11, and the external threaded tube 15 extends vertically through and to the top of the upper assembly seat 11. One side of the lower tooling mold 6 is fixed with an assembly pin 17 that engages with the lower assembly base 4, and the interior of the assembly pin 17 is slidably connected to an elastic locking block 18 via a spring 16. The lower assembly seat 4 is provided with a disassembly reserved hole 5 that matches the elastic locking block 18.

[0021] In use, the lower tooling mold 6 is engaged with the lower assembly seat 4 via the assembly pin 17. The elastic locking block 18 inside the assembly pin 17 pops out under the action of the spring 16 and engages with the slot of the lower assembly seat 4 to achieve quick fixation. If the mold structure needs to be changed according to the packaging product requirements, it can be unlocked by disassembling the reserved hole 5 and pressing the elastic locking block 18, making it easy to pull out the lower tooling mold 6 for replacement. Then, the user can use the threaded connection between the external threaded tube 15 and the upper assembly seat 11 to replace the upper tooling mold 10 that matches the lower tooling mold 6, thus enhancing applicability.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
