Description

Technical Field

[0001] This utility model relates to the field of thermal pad processing technology, and in particular to a tooling for integral molding of thermal pads. Background Technology

[0002] The integral molding of thermal pads involves pressing thermally conductive materials into the required shape and thickness of a thermally conductive pad through a cavity formed by the closure of an upper and lower mold under specific temperature and pressure conditions.

[0003] Patent CN215360066U discloses a molding die for preparing high thermal conductivity gaskets. The die includes a mold base with symmetrically distributed mold boxes on its upper end. Mold covers are located at adjacent ends of the mold boxes. A tray is slidably mounted on the inner wall of each mold box. An installation box is fixedly mounted on the inner wall of the mold base. Fixing plates are symmetrically fixedly mounted on the inner wall of the installation boxes. A screw is rotatably mounted inside the installation boxes, and a connecting rod is threaded onto the outer circumference of the screw. Fixing posts are symmetrically rotatably mounted at both ends of the connecting rod. While this patent achieves the effect of removing the finished gasket by rotating a handle to move the tray and the prepared gasket outward from the mold box, in practical applications, the thermally conductive gasket material itself has strong adhesive properties. During demolding, it easily adheres to the inner wall of the mold cavity, leading to edge tearing, surface damage, or even breakage of the gasket, affecting product yield and consistency.

[0004] Therefore, a tooling for integrally molding thermal pads is needed to prevent them from sticking to the cavity. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents in practical applications, where the thermal pad material itself has strong adhesion and is still prone to sticking to the inner wall of the mold cavity during demolding, resulting in tearing of the pad edge, surface damage or even breakage, affecting product yield and consistency, this utility model provides a thermal pad integral molding tooling to prevent the thermal pad from sticking to the mold cavity.

[0006] Technical Solution: A tooling for integral molding of thermal pads includes a fixed base, a lower mold, guide rods, a connecting plate, an upper mold, a cylinder, and a fixing structure. The lower mold is detachably mounted on the lower part of the fixed base. Two guide rods are fixedly connected to both the front and rear sides of the fixed base. A connecting plate is slidably mounted on multiple guide rods. The upper mold is detachably mounted on the bottom of the connecting plate. A cylinder is installed at the top center of the fixed base. The piston rod of the cylinder passes through the top of the fixed base and is fixedly connected to the connecting plate. Fixing structures are provided on the lower left and right sides of the fixed base and on the left and right sides of the connecting plate. The fixing structures on the fixed base are used to lock the lower mold. The fixing structure on the mounting plate is used to lock the upper mold. It also includes electric guide rails, mounting plate, electric slider, fixing frame, delivery pipe, nozzle and connecting sleeve. The mounting plate is fixedly installed on the rear side of the fixing base. Two electric guide rails are installed vertically on the mounting plate to the lower mold. Each electric guide rail has an electric slider that slides on it. The top of the two electric sliders are fixedly connected to the fixing frame. The delivery pipe is installed on the fixing frame. The delivery pipe has a three-way structure and multiple nozzles are connected to the side of it facing the lower mold. The nozzles are used to evenly spray the release agent onto the cavity surface of the lower mold. The end of the delivery pipe away from the lower mold is provided with a connecting sleeve.

[0007] Furthermore, it is particularly preferred that the fixing structure includes guide blocks, slide rods, locking blocks, elastic elements, and fixing blocks. Guide blocks are installed on the left and right sides of the lower part of the fixing base and on the left and right sides of the connecting plate. Slide rods are slidably arranged on the guide blocks. Locking blocks are fixedly connected to the end of the slide rod away from the guide blocks. Elastic elements are sleeved on the slide rods. The two ends of the elastic elements are connected to the guide blocks and locking blocks respectively. Fixing blocks are fixedly connected to the left and right sides of the lower mold and the left and right sides of the upper mold. Locking blocks are engaged in the locking slots of the fixing blocks.

[0008] In addition, it is particularly preferred that the device also includes a limiting plate. Two limiting plates are fixedly connected to the left and right sides of the lower part of the fixed base and the left and right sides of the bottom of the connecting plate. The limiting block on the fixed base contacts the outer side of the lower mold, and the limiting block on the connecting plate contacts the outer side of the upper mold.

[0009] Furthermore, it is particularly preferred that the device also includes a sensor, which is mounted on the rear side of the bottom of the connecting plate and is located above the mounting bracket.

[0010] In addition, it is particularly preferred that the mounting plate also includes a mounting bracket and wiping blocks, with the mounting bracket mounted on the mounting plate and multiple wiping blocks provided on the mounting bracket.

[0011] Furthermore, it is particularly preferred that the slide bar also includes a pull ring, with the pull ring provided at the end of the slide bar away from the locking block.

[0012] Compared with the prior art, this utility model provides an integrated molding tooling for thermal conductive pads, which has the following beneficial effects: 1. By starting the electric guide rail, the electric slider and the fixing frame are driven to move as a whole, and the nozzle is transported to the top of the lower mold cavity. The release agent is distributed to each nozzle through the delivery pipe and then evenly sprayed onto the surface of the lower mold cavity, thereby effectively preventing the thermal conductive pad after molding from sticking to the cavity, ensuring that the product can be demolded smoothly and completely, and avoiding cracking.

[0013] 2. By pulling the slide bar outward again, the locking block can be disengaged from the locking slot of the fixing block, allowing for quick disassembly of the upper or lower mold. The entire assembly and disassembly process is simple and efficient, significantly improving production flexibility and maintenance convenience. Attached Figure Description

Figures 1-6The system includes a fixed base 1, a lower mold 2, guide rods 3, a connecting plate 4, an upper mold 401, a cylinder 5, and a fixing structure. The lower mold 2 is detachably mounted on the lower part of the fixed base 1. Two guide rods 3 are fixedly connected to the front and rear sides of the fixed base 1. The four guide rods 3 are slidably mounted on the connecting plate 4. The upper mold 401 is detachably mounted on the bottom of the connecting plate 4. The cylinder 5 is mounted at the top center of the fixed base 1. The piston rod of the cylinder 5 passes through the top of the fixed base 1 and is fixedly connected to the connecting plate 4. Fixing structures are provided on the lower left and right sides of the fixed base 1 and on the left and right sides of the connecting plate 4. The fixing structures on the fixed base 1 are used to lock the lower mold 2, and the fixing structures on the connecting plate 4 are used to lock the upper mold 401. The fixing structure includes a guide block 11. The system includes a slide rod 12, a locking block 13, an elastic element 14, and a fixing block 15. Guide blocks 11 are installed on the lower left and right sides of the fixed base 1 and the left and right sides of the connecting plate 4. A slide rod 12 is horizontally slidably mounted on the guide block 11. A locking block 13 is fixedly connected to the end of the slide rod 12 away from the guide block 11. An elastic element 14 is sleeved on the slide rod 12. The two ends of the elastic element 14 are connected to the guide block 11 and the locking block 13, respectively. Fixing blocks 15 are fixedly connected to the left and right sides of the lower mold 2 and the left and right sides of the upper mold 401. The locking block 13 is inserted into the locking slot of the fixing block 15. The system also includes an electric guide rail 6, a mounting plate 601, an electric slider 7, a fixing frame 8, a conveying pipe 9, a nozzle 901, and a connecting sleeve 10. The mounting plate 601 is fixedly installed on the rear side of the fixed base 1. 1. Two electric guide rails 6 are installed vertically on the lower mold 2 on the mounting plate 601. Each electric guide rail 6 has a sliding electric slider 7. The tops of the two electric sliders 7 are fixedly connected to a fixing frame 8. A conveying pipe 9 is installed on the fixing frame 8. The conveying pipe 9 has a three-way structure and three nozzles 901 are connected to the side facing the lower mold 2. The nozzles 9017 are used to evenly spray the release agent onto the cavity surface of the lower mold 2. A connecting sleeve 10 is provided at the end of the conveying pipe 9 away from the lower mold 2. It also includes a limiting plate 16. Two limiting plates 16 are fixedly connected to the lower left and right sides of the fixing base 1 and the bottom left and right sides of the connecting plate 4. The limiting blocks on the fixing base 1 are in contact with the outer side of the lower mold 2, and the limiting blocks on the connecting plate 4 are in contact with the outer side of the upper mold 401. Contact is used to limit the horizontal displacement of the mold, ensure accurate alignment of the upper and lower molds 2 during mold closing, improve molding accuracy and repeatability stability. A sensor 17 is installed on the rear bottom of the connecting plate 4. The sensor 17 is a position sensor located above the fixed frame 8 to detect the position status of the fixed frame 8, ensure coordinated action and avoid interference. A mounting bracket 18 is installed on the mounting plate 601. Three wiping blocks 19 are provided on the mounting bracket 18. When the nozzle 901 is not working, the wiping blocks 19 contact the nozzle 901 to clean the nozzle 901 and prevent clogging. A pull ring 20 is provided at the end of the slide bar 12 away from the locking block 13 to increase the force point between the hand and the slide bar 12, making it easier to pull the slide bar 12.

[0023] Before molding the thermal pad, first pull the slide bar 12 outward. The slide bar 12 drives the locking block 13 to move outward against the elastic force of the elastic element 14. Then, place the lower mold 2 at the predetermined position under the fixed base 1, release the slide bar 12, and under the reset action of the elastic element 14, the locking block 13 moves inward and locks into the slot of the fixing block 15 on the side of the lower mold 2, thus completing the fixing of the lower mold 2. The upper mold 401 is fixed to the bottom of the connecting plate 4 through the same principle. After the preparation is complete, the release agent is sprayed first. Start the electric guide rail 6, drive the electric slider 7 and the fixing frame 8 to move as a whole, and transport the nozzle 901 to the top of the cavity of the lower mold 2. The delivery pipe 9 is connected to the release agent supply system through the connecting sleeve 10. The release agent is distributed to each nozzle 901 through the delivery pipe 9 and then evenly sprayed onto the surface of the cavity of the lower mold 2, thereby effectively preventing After molding, the heat-conducting pad adheres to the cavity, ensuring smooth and complete demolding of the product and preventing breakage. After spraying, the nozzle 901 mechanism moves back to its original position under the drive of the electric guide rail 6. Then, the cylinder 5 is activated, and the piston rod of the cylinder 5 extends downward, pushing the connecting plate 4 smoothly down along the guide rod 3, driving the upper mold 401 to descend synchronously until the upper mold 401 and the lower mold 2 are completely closed, forming a complete molding cavity. After molding and curing, the piston rod of the cylinder 5 retracts upward, driving the connecting plate 4 and the upper mold 401 to move upward, realizing mold opening. The molded heat-conducting pad can then be removed from the lower mold 2. When it is necessary to change the mold, the slide rod 12 is pulled outward again to disengage the locking block 13 from the locking slot of the fixing block 15, allowing for quick disassembly of the upper mold 401 or the lower mold 2. The entire assembly and disassembly process is simple and efficient, significantly improving production flexibility and maintenance convenience.
