Description

Technical Field

[0001] This utility model relates to the field of silicone encapsulation mold technology, specifically a quick-change structure for silicone encapsulation molds. Background Technology

[0002] In the manufacturing process of high-precision products such as electronic components and medical devices, silicone encapsulation is a crucial protective process. The core of this process is to precisely encapsulate liquid silicone material around the core modules and precision circuits of the product. After curing, it forms a dense and flexible solid protective layer. Its main function is to build a strong barrier for the delicate internal components, effectively preventing the intrusion of moisture, humidity (moisture-proof), dust, impurities, corrosive chemical gases, and salt spray from the external environment.

[0003] As disclosed in utility model publication CN222040948U, a packaging mold for a packaging machine includes a metal mold body in the shape of a rectangular block. Multiple linearly distributed mounting holes are provided on the top, bottom, left, and right sides of the mold body. Each mounting hole vertically penetrates the mold body. A protrusion is secured within each mounting hole by an annular limiting step. The top of the protrusion protrudes above the mounting hole. A screw is threaded to the bottom of each mounting hole, and a spring is provided between the screw and the bottom of the protrusion. Multiple packaging grooves are provided in the center of the top surface of the mold body.

[0004] However, existing equipment has limitations when changing molds. It requires external handling machines for handling and placing, which increases the investment cost of production equipment. It also consumes extra time due to the scheduling of handling machines and the alignment adjustment of molds during handling. Furthermore, the equipment will continuously vibrate during the silicone encapsulation process, resulting in poor mold stability and loosening, which can lead to quality problems such as dimensional deviations and glue overflow in the encapsulated products. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change structure for silicone encapsulation molds, so as to solve the limitations mentioned in the background art when changing molds. It requires external handling machines for handling and placing, which increases the investment cost of production equipment. It also consumes extra time due to the scheduling of handling machines and the alignment adjustment of molds during handling. Furthermore, the equipment will continuously vibrate during the silicone encapsulation process, resulting in poor mold stability and easy loosening, which leads to quality problems such as dimensional deviations and glue overflow in the encapsulated products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change structure for silicone encapsulation molds, including a base, a square groove on the left side of the base, a first movable roller rotatably connected in the square groove, T-shaped grooves on both sides of the top left end of the base, a T-shaped block in the T-shaped groove, a frame fixedly connected to the outer end of the T-shaped block, and the base and the frame are engaged with the T-shaped block through the T-shaped groove, and a second movable roller rotatably connected in the frame.

[0007] Furthermore, a reinforcing rib is fixedly connected to the right side of the bottom of the frame, and the reinforcing rib is triangular in shape, and the reinforcing rib abuts against the outer wall of the base.

[0008] Furthermore, side plates are fixedly connected to both sides of the top of the frame, and grooves are evenly provided on the side plates, with limit rods installed in the grooves.

[0009] Furthermore, both ends of the top left side of the base are rotatably connected to a rotating shaft, a limit block is fixedly connected to the outer wall of the rotating shaft, and a handle is fixedly connected to the top of the rotating shaft.

[0010] Furthermore, a sliding groove is provided on the right side of the top of the base, and a lead screw is rotatably connected in the sliding groove. A servo motor is fixedly connected to the middle of the outer wall of the right end of the base, and the servo motor is fixedly connected to the lead screw. A slider adapted to the sliding groove is threaded onto the lead screw, and a push plate is fixedly connected to the top of the slider.

[0011] Furthermore, anti-slip protrusions are uniformly fixedly connected to the inner wall of the push plate, and the anti-slip protrusions are hemispherical in shape.

[0012] Furthermore, the top of the base is provided with a mold body, and movable grooves are provided on both sides of the bottom of the mold body. Bolts are provided in the movable grooves and extend through to the bottom of the base. Washers are fitted on the bolts and abut against the top of the base. Nuts are threaded to the end of the bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The quick-change structure for silicone encapsulation molds, with the first moving roller in the square groove on the left side of the base and the second moving roller installed inside the frame of the base via a T-shaped block and T-groove, together form a dual-roller cooperative moving structure. This structure can directly push the mold body to complete the pick-up, drop-off, and switching operations without relying on external handling equipment. This not only saves the purchase and maintenance costs of external handling equipment but also completely avoids the additional time-consuming steps of external machine scheduling and mold alignment adjustment. At the same time, in conjunction with the lead screw and slider driven by the servo motor on the right side of the base, the push plate can assist in accurately pushing the mold body to the designated installation position, greatly improving efficiency. Shortening the changeover cycle and effectively improving production continuity, on the one hand, the side plates fixed on both sides of the top of the frame have grooves evenly opened on their surfaces into which limit rods can be embedded. The two work together to form a lateral blocking structure, which can effectively limit the mold body that is about to be installed or changed, preventing the mold from slipping off the sides of the device during the movement along the double rollers, significantly improving operational safety. On the other hand, the tight engagement of the T-slot and the T-block can strictly limit the movement trajectory of the frame and the second moving roller, ensuring that they always run along a fixed path, avoiding misalignment between the mold body and the base installation position due to frame offset, and ensuring the subsequent packaging accuracy.

[0014] (2) The quick-change structure of the silicone encapsulation mold has a set of movable grooves on both sides of the bottom of the mold body to provide installation channels for bolts. The bolts can pass through the movable grooves and extend to the bottom of the base to form a longitudinal connection between the mold and the base. At the same time, a gasket is fitted at the contact position between the bolt and the base. The gasket tightly abuts against the top of the base, which can increase the contact area between the bolt and the base and disperse the tightening pressure. Finally, by tightening the nut at the end of the bolt, the nut, the base, the gasket and the mold body form a tight-fitting compression structure, which can effectively buffer the continuous vibration generated by the equipment during the silicone encapsulation process and prevent the mold body from shifting or loosening due to vibration, thus providing a stable guarantee for the dimensional accuracy and anti-overflow effect of the subsequent encapsulation operation.

[0015] Furthermore, the hemispherical anti-slip protrusions on the inner wall of the push plate can increase the friction with the mold body, which can not only help fix the mold, but also accurately push the mold to the first moving roller area during switching, reducing quality problems such as product size deviation and glue overflow. The triangular reinforcing rib on the right side of the bottom of the frame abuts against the outer wall of the base, using the principle of triangle stability to enhance the load-bearing capacity of the frame and prevent the frame from deforming after long-term use. By turning the handle to drive the rotating shaft and the limiting block to rotate, the limiting of the T-block can be quickly released, which facilitates the disassembly and maintenance of the frame and the second moving roller.

[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. 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.

[0019] Example 1: A quick-change structure for silicone encapsulation molds. The mold body 3 is initially moved by a first moving roller 11, and then moved a second time by a second moving roller 131 within a frame 13. A T-shaped block 121 and a T-shaped groove 12 are used to mount the frame 13 and the second moving roller 131. A limiting block 171 is used to limit and fix the T-shaped block 121. The side plate 15, groove 151, and limiting rod 16 work together to limit the molds to be installed or switched, preventing them from falling. A push plate 21 and other components limit the mold body 3 while pushing it towards the first moving roller 11. This prevents limitations during mold switching that would otherwise require external handling equipment, increasing production equipment costs and consuming additional time due to the scheduling of handling equipment and the alignment adjustments during handling.

[0020] like Figure 1 - Figure 5As shown, a quick-change structure for silicone encapsulation molds includes a base 1. A square groove is formed on the left side of the base 1, and a first moving roller 11 is rotatably connected within the groove. This first moving roller 11, after contacting the bottom of the mold body 3, assists the mold in continuing to move using its own rolling characteristics until it reaches a preset installation position. T-shaped grooves 12 are formed on both sides of the top left end of the base 1, and T-shaped blocks 121 are disposed within the T-shaped grooves 12. A frame 13 is fixedly connected to the outer end of each T-shaped block 121. The base 1 and the frame 13 are connected by engaging the T-shaped blocks 121 through the T-shaped grooves 12. This combined structure enables precise installation of the frame 13, providing a stable connection for subsequent mold transport. A second movable roller 131 is rotatably connected inside the frame 13. When the mold body 3 is placed inside the frame 13, the second movable roller 131 utilizes its rolling characteristics to initially transport the mold to the area above the base 1. A reinforcing rib 14 is fixedly connected to the right side of the bottom of the frame 13. The reinforcing rib 14 is triangular in shape and abuts against the outer wall of the base 1. Utilizing the stability characteristics of a triangle, the reinforcing rib 14 enhances the load-bearing capacity of the frame 13, preventing deformation or displacement of the frame 13 during subsequent mold movement. Side plates 15 are fixedly connected to both sides of the top of the frame 13. Grooves 151 are evenly distributed on the side plates 15. A limit rod 16 is provided. Two rotating shafts 17 are rotatably connected to both ends of the top left side of the base 1. A limit block 171 is fixedly connected to the outer wall of the rotating shaft 17. A handle 172 is fixedly connected to the top of the rotating shaft 17. Rotating the handle 172 can drive the rotating shaft 17 to rotate synchronously, causing the limit block 171 to rotate to a position that fits against the top of the T-shaped block 121, thereby forming a longitudinal limit on the T-shaped block 121 and further locking the frame 13, ensuring that it always runs along a fixed trajectory during mold conveying. A slide groove is provided on the right side of the top of the base 1, and a lead screw 2 is rotatably connected in the slide groove. A servo motor is fixedly connected to the middle of the outer wall of the right end of the base 1, and the servo motor is fixedly connected to the lead screw 2. When the servo motor is started, the output shaft of the motor can drive the lead screw 2 to rotate, providing power for the movement of the slider. The lead screw 2 is threaded with a slider that matches the slide groove. The top of the slider is fixedly connected to a push plate 21. When the lead screw 2 rotates, the slider will move along the slide groove, thereby driving the push plate 21 to move synchronously. Anti-slip protrusions 211 are evenly fixedly connected on the inner wall of the push plate 21, and the anti-slip protrusions 211 are hemispherical in shape. When the push plate 21 approaches the mold body 3, and the anti-slip protrusions 211 are completely in contact with the outer wall of the mold body 3, the friction with the mold can be increased to form a reliable lateral limit on the mold body 3, preventing the mold from shifting in the horizontal direction.

[0021] In use, first, the frame 13 is precisely engaged with the T-shaped block 121 at its bottom and the T-shaped groove 12 at the top left of the base 1 to complete the installation. At this time, the triangular reinforcing rib 14 on the bottom right of the frame 13 is tightly abutted against the outer wall of the base 1, enhancing the load-bearing capacity of the frame 13. Then, the handles 172 at both ends of the top left of the base 1 are rotated to drive the rotating shaft 17 to rotate synchronously, so that the limiting block 171 on the outer wall of the rotating shaft 17 rotates to the position of fitting the top of the T-shaped block 121, forming a longitudinal limit on the T-shaped block 121, further locking the frame 13. Then, the mold body 3 to be installed is placed stably on the second moving roller 131 inside the frame 13, and the mold body 3 is pushed, using the second moving roller 131 to move the mold body 13. The rolling characteristics of the two moving rollers 131 initially transport the mold to the area above the base 1. After the bottom of the mold body 3 contacts the first moving roller 11 on the left side of the base 1, the mold continues to be pushed until it reaches the preset installation position. Finally, the servo motor in the middle of the outer wall of the right end of the base 1 is started. The output shaft of the motor drives the lead screw 2 in the slide groove on the right side of the top of the base 1 to rotate. The slider connected to the thread on the lead screw 2 moves to the left along the slide groove, thereby driving the push plate 21 on the top of the slider to move closer to the mold body 3. When the hemispherical anti-slip protrusions 211 evenly distributed on the inner wall of the push plate 21 are completely in contact with the outer wall of the mold body 3, the servo motor stops running, realizing the lateral limit of the mold body 3.

[0022] Example 2: Unlike Example 1, the mold body 3 is fixedly installed by the synergistic action of components such as bolts 32, washers 321, and nuts 33. This prevents the equipment from continuously vibrating during the silicone encapsulation process, which would result in poor mold stability, loosening, and quality problems such as dimensional deviations and glue overflow in the encapsulated products.

[0023] like Figure 6 As shown, a mold body 3 is provided on the top of the base 1, which provides the core forming space of the mold and is the key carrier for workpiece processing. Movable grooves 31 are provided on both sides of the bottom of the mold body 3 to provide installation and adjustment space for bolts 32, so that the bolts 32 can be inserted and adapted to the installation position of the mold body 3. The bolts 32 are installed in the movable grooves 31 as the core connecting parts for longitudinal fixation. By inserting into the movable grooves 31 and passing through the base 1, the initial connection between the mold body 3 and the base 1 is achieved, and the bolts 32 pass through to the bottom of the base 1. A washer 321 is fitted on the bolt 32 to increase the contact area between the bolt 32 and the base 1, to distribute the pressure generated when the bolt 32 is tightened, to avoid damage to the top of the base 1 due to excessive local pressure, and to improve the stability of the connection. The washer 321 abuts against the top of the base 1. The end of the bolt 32 is threaded with a nut 33. By engaging with the thread of the bolt 32, after tightening, the mold body 3, the washer 321 and the base 1 can be tightly locked together to complete the longitudinal fixation.
