Description

Technical Field

[0001] This utility model relates to the technical field of producing silicone rubber granules with threaded rods, particularly top plates. Background Technology

[0002] The silicone rubber granules with rods consist of conductive screws encasing conductive silicone rubber. Existing production technology involves first placing several screws into blind holes in a lower mold. Then, a block of conductive silicone rubber material mixed with a crosslinking agent is placed on top of the screws. An upper mold is then placed on top of the lower mold, with the forming recess on the upper mold aligned with the conductive silicone rubber block on the rod. While heating the conductive silicone rubber block, the lower and upper molds are gradually closed. The hot-melt conductive silicone rubber material encapsulates the screw heads and fills the forming recess, completing the molding process. Simultaneously, the crosslinking agent reacts with the conductive silicone rubber material. After molding, the lower and upper molds are separated, thus completing the manufacturing of the conductive silicone rubber granules with rods. However, after several conductive silicone rubber granules with rods are formed, a thin layer of excess silicone rubber remains, binding them together. Existing technology involves manually removing this excess silicone rubber from each granule, which is not only labor-intensive but also inefficient and costly. Summary of the Invention

[0003] The purpose of this invention is to provide a top plate that can overcome one or more of the above-mentioned disadvantages, save manpower, significantly improve production efficiency, and reduce production costs.

[0004] The top plate of this utility model is implemented as follows: it includes a base and several ejector pins disposed on the base. The number and position of the ejector pins match the position of the rods of several conductive silicone rubber particles with rods formed on a perforated intermediate plate, which are connected by a layer of silicone rubber excess film. The diameter of the ejector pins is not greater than the diameter of the perforation in the intermediate plate.

[0005] In use, several conductive silicone rubber granules with rods are connected together by a layer of conductive silicone rubber excess film and formed on a perforated intermediate plate. The rods pass through the perforations in the intermediate plate. To peel the conductive silicone rubber granules with rods from the intermediate plate, the intermediate plate and the demolding mold are placed between the two plates of the press. The demolding mold is a plate-shaped object with several through holes. The size of the through holes matches the size of the conductive silicone rubber granules, and the position of the through holes on the plate matches the position of the conductive silicone rubber granules on the intermediate plate. Several conductive silicone rubber granules with rods, connected together by a membrane, are placed in corresponding through holes in a plate-shaped object. The rods are pressed towards the plate-shaped object by a press, causing the rods to move relative to the through holes. This forces the conductive silicone rubber granules with rods into the through holes of the plate-shaped object, causing them to peel off from the excess conductive silicone rubber membrane. The intermediate plate is then moved to the base of the top plate, with the ejector pin pointing towards the rod end face of the plastic granule. The intermediate plate is pressed down, and the ejector pin pushes the rod of the conductive silicone rubber granule out of the through hole in the intermediate plate, completely detaching the conductive silicone rubber granule from the excess conductive silicone rubber membrane.

[0006] A plate-shaped device with through holes is used. The cross-sectional shape and size of the through holes match the shape and size of the bottom surface of the conductive silicone rubber particles. The opening of the through hole acts like a blade. As the conductive silicone rubber particles with rods move rapidly relative to the plate-shaped device, the excess conductive silicone rubber film around the conductive silicone rubber particles can be effectively cut off, ensuring the quality of the cut. Because multiple conductive silicone rubber particles with rods are cut off quickly at once, the production efficiency is high, the production cost is low, and labor is saved. After the excess conductive silicone rubber film is cut off, the elasticity of the excess conductive silicone rubber film will cause the hole to shrink, trapping the conductive silicone rubber particles. At the same time, the end of the rod remains in the through hole of the intermediate plate, keeping the conductive silicone rubber particles on the intermediate plate. The rod is pushed out of the through hole of the intermediate plate by the ejector pin on the base of the top plate, thus removing all the conductive silicone rubber particles stuck on the intermediate plate at once, achieving the purpose of quickly collecting the conductive silicone rubber particles.

[0007] Preferably, the base is provided with guide posts around its perimeter, and the intermediate plate that matches the guide posts is provided with guide holes, so that the guide posts of the base can be inserted into the guide holes of the intermediate plate and the intermediate plate can be pressed down. The ejector pins on the base are inserted into the through holes of the intermediate plate, and the plastic particles are pushed away from the intermediate plate by the rod that ejects the plastic particles.

[0008] Compared with existing technologies, this utility model has the advantages of saving manpower, significantly improving production efficiency, and reducing production costs. Attached Figure Description

Detailed Implementation

[0016] The top plate of this utility model will now be described in further detail with reference to the accompanying drawings and embodiments:

[0017] like Figure 1 As shown, the top plate of this utility model includes a base 8 and several pins 9 disposed on the base 8. The number and position of the pins 9 match the position of the rods 4 of several conductive silicone rubber particles 5 with rods formed on the intermediate plate 3 with perforations 7, which are connected by a layer of silicone rubber excess film 6. The diameter of the pins 9 is not greater than the diameter of the perforations 7 of the intermediate plate 3.

[0018] like Figure 1 As shown in Figure 6, the mold for cleaning excess material 16 from conductive silicone rubber granules with rods in this invention is implemented as follows: It includes a plate-shaped object 1, several through holes 2 on the plate-shaped object 1, an intermediate plate 3, and several conductive silicone rubber granules 5 with rods 4 connected together by a silicone rubber excess material film 6. The rods 4 of the conductive silicone rubber granules 5 pass through several through holes 7 on the intermediate plate 3, the positions of which match the positions of the conductive silicone rubber granules 5 connected together by the silicone rubber excess material film 6. The cross-sectional shape and size of the through holes 2 on the plate-shaped object 1 match the shape and size of the bottom surface of the conductive silicone rubber granules 5. The positions of the through holes 2 on the plane of the plate-shaped object 1 match the positions of the conductive silicone rubber granules 5 with rods 4 connected together by the silicone rubber excess material film 6. Figure 2As shown, the intermediate plate 3 and the plate-shaped object 1 are both placed between the two pressure plates 11 of the press 10. Several conductive silicone rubber particles 5 with rods 4, which are connected together by a layer of silicone rubber excess film 6, are placed in the corresponding holes 2 of the plate-shaped object 1. The press 10 squeezes the rods towards the plate-shaped object 1, causing the rods 4 to move relative to the through holes 2, squeezing the conductive silicone rubber particles 5 with rods 4 into the through holes 2 of the plate-shaped object 1, so that the conductive silicone rubber particles 5 are peeled off from the silicone rubber excess film 6. The intermediate plate 3 is moved to the base 8 of the top plate, and the ejector pin 9 is positioned opposite the end face of the rod 4 of the conductive silicone rubber particles 5. The intermediate plate 3 is pressed down, and the ejector pin 9 pushes the rod 4 of the conductive silicone rubber particles 5 out of the through holes 7 of the intermediate plate 3, so that the silicone rubber particles 5 are completely separated from the silicone rubber excess film 6.

[0019] Preferably, such as Figure 1 , 4 As shown, guide posts 12 are provided around the base 8, and guide holes 13 are provided on the intermediate plate 3 that match the guide posts 12, so that the guide posts 12 of the base 8 can pass into the guide holes 13 of the intermediate plate 3.

[0020] Preferably, such as Figure 6 As shown, the upper port 14 of the perforation 7 of the intermediate plate 3 is trumpet-shaped. After the conductive silicone rubber granules 5 are formed, a conical excess 15 at the root of the rod 4 is connected to the excess 16 that has seeped into the rod 4. When cleaning the excess 16, by detaching the conductive silicone rubber granules 5 with the rod 4 from the intermediate plate 3, the conical excess 15 is cleaned out, and at the same time, the excess 16 on the rod 4 (inside the threads) is also cleaned out, thereby accelerating the cleaning of excess and improving production efficiency.

[0021] like Figure 2 , 3 As shown, a plate-shaped object 1 with a through hole 2 is used. The cross-sectional shape and size of the through hole 2 match the shape and size of the bottom surface of the conductive silicone rubber particle 5. The opening of the through hole 2 is equivalent to a blade. During the rapid relative movement of the conductive silicone rubber particle 5 with rod 4 and the plate-shaped object 1, the excess silicone rubber film 6 around the conductive silicone rubber particle 5 can be effectively cut off, and the quality of the cutting can be guaranteed. Since multiple conductive silicone rubber particles 5 with rod 4 are cut off quickly at one time, the production efficiency is high, the production cost is low, and labor is saved. After the excess silicone rubber film 6 is cut off, the elasticity of the excess silicone rubber film 6 will cause the hole to shrink, clamping the conductive silicone rubber particle 5. At the same time, the end of the rod 4 remains in the through hole 7 of the intermediate plate 3, so that the conductive silicone rubber particle 5 remains on the intermediate plate 3. Figure 4 , 5 As shown, by pushing the rod 4 out of the through hole 7 of the intermediate plate 3 through the ejector pin 9 on the base 8, all the conductive silicone rubber particles 5 stuck on the intermediate plate 3 can be pushed away from the intermediate plate 3 at once, thus achieving the purpose of quickly collecting the conductive silicone rubber particles.
