Description

Technical Field

[0001] This invention relates to the field of transparent protective cover processing technology for surge arresters, specifically a composite transparent protective cover for surge arresters and its processing technology. Background Technology

[0002] This invention relates to the field of transparent protective cover processing technology for surge arresters, specifically a composite transparent protective cover for surge arresters and its processing technology. Surge arresters, as key components in power systems that ensure equipment safety and prevent overvoltage damage, are susceptible to environmental factors such as wind, rain, dust, condensation, and collisions with foreign objects during outdoor use. Therefore, they require protective covers. Transparent protective covers, which allow for direct observation of the surge arrester's operating status, are the preferred solution for outdoor surge arrester protection.

[0003] Existing composite surge arrester transparent protective covers are mostly made of silicone rubber through molding, which has many drawbacks in structural design and processing applications: First, the protective cover body lacks a dedicated positioning structure, making it prone to axial rotation during processing, resulting in poor subsequent flash removal. Second, the protective cover has an irregular shape, and the flash at the gap between its transparent shell and the cable cover is difficult to clean quickly with conventional equipment. Manual flash removal is inefficient, labor-intensive, and easily damages the transparent structure of the protective cover. Third, traditional flash removal equipment can only perform a single scraping action, and the fit between the scraper and the gap of the protective cover is poor, resulting in poor flash removal. At the same time, the removed flash cannot be collected in time and tends to accumulate at the equipment, affecting the continuity of processing.

[0004] Based on this, a composite surge arrester transparent protective cover and its processing technology are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a composite surge arrester transparent protective cover and its processing technology to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A transparent protective cover for a composite surge arrester and its processing technology are disclosed. The cover includes a transparent shell, edges, an opening, and a cable cover. Both the transparent shell and the cable cover are transparent and have an internal cavity adapted to the composite surge arrester. The cable cover is fixedly connected to the side wall of the transparent shell. Both the transparent shell and the cable cover have slits for easy opening. The transparent shell has edges on its periphery to facilitate adaptation to a special processing device and prevent movement during processing. The bottom of the transparent shell has an opening.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions: The manufacturing process of the transparent protective cover for composite surge arresters includes the following steps: S1: Silicone raw rubber, reinforcing agent, structure control agent, vulcanizing agent and various functional additives are put into the mixing equipment according to the ratio. Through repeated kneading and mixing, the various additives are evenly dispersed in the silicone rubber to form the final compound for molding. S2: The mixed rubber compound is further thinned and rolled on a two-roll mill to plasticize and soften it, achieving the required softness and thickness for compression molding. The treated rubber compound is then cut into blanks of specific weight and shape for later use. S3: Place the cut rubber blank into the preheated metal mold cavity. After the mold is closed, vulcanize under high temperature and high pressure. The pressure makes the rubber fill every corner of the mold, and the high temperature triggers the vulcanization reaction, causing the linear silicone rubber molecular chains to cross-link into a three-dimensional network structure, changing from plastic to elastomer. S4: Place the molded and pre-trimmed protective cover into an oven and bake at a constant temperature of 200℃ for several hours; S5: After the product cools down, use a flash removal device to remove the flash generated during molding. Finally, conduct strict spot checks on appearance, dimensions and electrical performance. Only products that pass the checks can be packaged and put into storage.

[0008] The flash removal device for the processing technology includes a positioning component and a flash removal component. The positioning component is used to quickly complete the processing and positioning of the protective cover. The flash removal component is used to quickly remove flash from the protective cover with irregular structure. The flash removal component includes a fixed shell, a first scraper, a second scraper, and a drive module. The second scraper is fixedly connected to the inner wall of the fixed shell. The second scraper is fixedly connected to the guide rail cylinder. The second scraper and the first scraper are adapted to the gap between the transparent cover and the cable cover. The cable cover passes through the fixed shell. The drive module is used to drive the first scraper and the second scraper to remove flash from the protective cover.

[0009] In one alternative embodiment: the drive module includes a guide rail seat, a lead screw, and a first slider. The first slider is slidably connected to the inner wall of the guide rail seat. A fixed plate is fixedly connected to the upper surface of the first slider. The upper surface of the fixed plate is fixedly connected to the first guide rail and the second guide rail. The fixed plate is rotatably mounted with two symmetrical rotating shafts via bearing seats. The rotating shafts are fixedly connected to connecting rod fittings. The two connecting rod fittings are rotatably connected to the second slider via pins. The second slider is fixedly connected to a fixed shell. The fixed shell is slidably connected to the first guide rail. The second slider is slidably connected to the second guide rail. The guide rail seat is mounted with a lead screw via bearings. The lead screw is threadedly connected to the first slider. A motor for driving the lead screw to rotate is mounted on the side wall of the guide rail seat.

[0010] In one alternative: the rotating shaft is fixedly connected to a gear, and the side wall of the guide rail is fixedly connected to a rack, which meshes with the gear.

[0011] In one alternative: a plurality of mounting blocks are fixedly connected to the inner wall of the fixed housing; a rotating plate is connected to the inner wall of the mounting block via a pin; a pulley is connected to the rotating plate via a pin; a spring is fixedly connected between the rotating plate and the mounting block; the pulley abuts against the side wall of the cable cover; and a limit plate is fixedly connected to the side wall of the mounting block to limit the maximum rotation angle of the rotating plate.

[0012] In one alternative: the second slider and the fixed shell are rotatably connected to a vacuum cleaner through a bearing. The portion of the vacuum cleaner located inside the fixed shell has several suction holes. One end of the vacuum cleaner is fixedly connected to a guide rail cylinder. A spiral track is formed around the guide rail cylinder. A sliding head is fixedly connected to the upper surface of the second guide rail. The sliding head is slidably connected to the inner wall of the spiral track. One end of the guide rail cylinder is rotatably installed with a pipe connected to an external vacuum cleaner. A burr box is placed below the opening.

[0013] In one alternative: two convex rings are fixedly connected to the periphery of the vacuum cleaner, and several protrusions are provided on the periphery of the convex rings. Two notches corresponding to the convex rings are opened on the two side walls of the scraper. A fixed cylinder is fixedly connected to the inner wall of the two notches of the scraper. A striking block is slidably connected to the inner wall of the fixed cylinder. A spring is fixedly connected between the striking block and the inner wall of the fixed cylinder. The striking block abuts against the convex rings.

[0014] In one alternative embodiment: the positioning component includes a placement frame, a clamping block, and a pressing positioning block. The placement frame is fixedly mounted with the clamping block, which is made of an elastic material and has elastic deformation capability. The shape of the clamping block is adapted to the shape of the edges around the transparent cover. The pressing positioning block is rotatably mounted on the upper surface of the placement frame via a bearing seat shaft. A coil spring is installed between the pressing positioning block and the bearing seat.

[0015] In one alternative: two symmetrical side clamps are fixedly connected to the periphery of the fixed shell. A pulley is installed on the side wall of the side clamp via a pin. The side clamp is made of rigid material. The pulley abuts against the clamping block, and there is pressure between the pulley and the clamping block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The transparent cover of this invention has an added edge structure on its periphery, which is precisely matched with the clamping block of the special positioning component for processing, which can effectively prevent the protective cover from rotating axially during processing; at the same time, both the transparent cover and the cable cover have gaps that are easy to pry open, which not only facilitates on-site installation and disassembly, but also provides a precise scraping position for the deflashing process, taking into account both ease of use and processing adaptability.

[0017] The drive module of this invention uses a motor, lead screw, and gear rack transmission to achieve the lateral movement and high-frequency reciprocating motion of scraper one and scraper two, which can precisely scrape the gaps of the transparent shell of the irregular protective cover and the cable cover, replacing manual removal of burrs and increasing processing efficiency several times. At the same time, the scraper is precisely matched with the gap of the protective cover, and with the elastic pressure of pulley two on the cable cover and the squeezing force transmission of pulley one clamping block, the scraper is fully attached to the inner wall of the gap, the burrs are completely removed, and the product appearance quality is greatly improved.

[0018] The device of this invention is equipped with a vacuum cleaner that works in conjunction with an external vacuum cleaner. The vacuum cleaner rotates with the guide tube to achieve a range of rotation of the suction port, increasing the suction range and automatically collecting the removed burrs, avoiding the tediousness of manual collection. At the same time, the burr box assists in collecting burrs that fall into the gaps of the transparent cover, realizing the automation of burr cleaning. The cooperative structure of the convex ring and the striking block causes the vacuum cleaner to generate continuous vibration during rotation, effectively preventing burrs from clogging the suction port, ensuring the continuous and stable operation of the vacuum system, and realizing the continuous processing of burr removal.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-12 As shown, a transparent protective cover for a composite surge arrester and its processing technology include a transparent cover 1, a ridge 2, an opening 3, and a cable cover 4. Both the transparent cover 1 and the cable cover 4 are transparent structures and have an internal cavity adapted to the composite surge arrester. The cable cover 4 is fixedly connected to the side wall of the transparent cover 1. Both the transparent cover 1 and the cable cover 4 have slits that are easy to pry open. The transparent cover 1 has a ridge 2 on its periphery to facilitate adaptation to the processing device and prevent movement during processing. The bottom of the transparent cover 1 has an opening 3.

[0034] Compared with traditional surge arrester protective covers, the protective cover of the present invention has additional circumferential edges 2, which can better clamp the device during processing, making the processing more stable.

[0035] The manufacturing process of the transparent protective cover for composite surge arresters includes the following steps: S1: Silicone raw rubber, reinforcing agent, structure control agent, vulcanizing agent and various functional additives are put into the mixing equipment according to the ratio. Through repeated kneading and mixing, the various additives are evenly dispersed in the silicone rubber to form the final compound for molding. S2: The mixed rubber compound is further thinned and rolled on a two-roll mill to plasticize and soften it, achieving the required softness and thickness for compression molding. The treated rubber compound is then cut into blanks of specific weight and shape for later use. S3: Place the cut rubber blank into the preheated metal mold cavity. After the mold is closed, vulcanize under high temperature and high pressure. The pressure makes the rubber fill every corner of the mold, and the high temperature triggers the vulcanization reaction, causing the linear silicone rubber molecular chains to cross-link into a three-dimensional network structure, changing from plastic to elastomer. S4: Place the molded and pre-trimmed protective cover into an oven and bake at a constant temperature of 200℃ for several hours; S5: After the product cools down, use a flash removal device to remove the flash generated during molding. Finally, conduct strict spot checks on appearance, dimensions and electrical performance. Only products that pass the checks can be packaged and put into storage.

[0036] The flash removal device for the processing technology includes a positioning component 5 and a flash removal component 6. The positioning component 5 is used to quickly complete the processing and positioning of the protective cover. The flash removal component 6 is used to quickly remove flash from the protective cover with irregular structure. The flash removal component 6 includes a fixed shell 20, a scraper 1 27, a scraper 28 and a drive module. The scraper 28 is fixedly connected to the inner wall of the fixed shell 20. The scraper 28 is fixedly connected to the guide rail cylinder 17. The scraper 28 and scraper 1 27 are adapted to the gap between the transparent cover 1 and the cable cover 4. The cable cover 4 passes through the fixed shell 20. The drive module is used to drive the scraper 1 27 and scraper 2 28 to remove flash from the protective cover.

[0037] Scraper 28 inside the fixed shell 20 scrapes away the burrs from the gaps in the cable cover 4 of the protective cover, and scraper 27 scrapes away the burrs from the gaps in the transparent cover 1 of the protective cover.

[0038] In one embodiment, the drive module includes a guide rail seat 8, a lead screw 11, and a slider 12. The slider 12 is slidably connected to the inner wall of the guide rail seat 8. A fixing plate 13 is fixedly connected to the upper surface of the slider 12. A guide rail 14 and a guide rail 25 are fixedly connected to the upper surface of the fixing plate 13. Two symmetrical rotating shafts 23 are rotatably mounted on the fixing plate 13 through bearing seats. A connecting rod fitting 24 is fixedly connected to the rotating shaft 23. The two connecting rod fittings 24 are rotatably connected to a slider 25 through a pin. The slider 25 is fixedly connected to the fixing shell 20. The fixing shell 20 is slidably connected to the guide rail 14. The slider 25 is slidably connected to the guide rail 25. The lead screw 11 is mounted on the guide rail seat 8 through bearings. The lead screw 11 is threadedly connected to the slider 12. A motor 9 for driving the lead screw 11 to rotate is mounted on the side wall of the guide rail seat 8.

[0039] The motor 9 is started by an external controller. The motor 9 drives the lead screw 11 to rotate. The lead screw 11 drives the deflash removal component 6 on the slider 12 to move towards the protective cover position. The cable cover 4 of the protective cover first enters the fixed shell 20. As the deflash removal component 6 continues to move forward.

[0040] In one embodiment, a gear 22 is fixedly connected to the rotating shaft 23, and a rack 10 is fixedly connected to the side wall of the guide rail seat 8, with the rack 10 meshing with the gear 22.

[0041] As the fixed shell 20 moves toward the protective cover, the gear 22 meshes with the rack 10 and rotates. The gear 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the connecting rod engagement 24 to rotate. During the rotation of the connecting rod engagement 24, the slider 25 and the fixed shell 20 reciprocate on the guide rail 14 and the guide rail 25, so that the scraper 1 27 and the scraper 28 can perform high-frequency reciprocating motion to remove flash, further improving the flash removal effect of the flash removal assembly 6.

[0042] In one embodiment, a plurality of mounting blocks 30 are fixedly connected to the inner wall of the fixed shell 20. A rotating plate 31 is connected to the inner wall of the mounting block 30 via a pin. A pulley 33 is connected to the rotating plate 31 via a pin. A spring is fixedly connected between the rotating plate 31 and the mounting block 30. The pulley 33 abuts against the side wall of the cable cover 4. A limit plate 32 is fixedly connected to the side wall of the mounting block 30 to limit the maximum rotation angle of the rotating plate 31.

[0043] As the fixed shell 20 moves toward the protective cover, the pulley 2 33 inside the mounting block 30 abuts against the cable cover 4 of the protective cover. Under the action of the spring, the pulley 2 33 exerts pressure on the cable cover 4 of the protective cover, so that the inner wall of the gap at the position of the cable cover 4 can fully contact the scraper 2 28, thereby improving the scraper 2 28's effect of removing burrs.

[0044] In one embodiment, the second slider 25 and the fixed shell 20 are rotatably connected to a vacuum cleaner 18 via a bearing. The portion of the vacuum cleaner 18 located inside the fixed shell 20 has several suction holes. One end of the vacuum cleaner 18 is fixedly connected to a guide rail cylinder 17, which has a spiral track around its periphery. A sliding head 16 is fixedly connected to the upper surface of the second guide rail 15, and the sliding head 16 is slidably connected to the inner wall of the spiral track. One end of the guide rail cylinder 17 is rotatably fitted with a pipe connected to an external vacuum cleaner. A scrap box 7 is placed below the open opening 3. The scrap box 7 is used to collect scrap that falls from the gaps in the transparent cover 1.

[0045] When the external vacuum cleaner is turned on, it creates negative pressure inside the vacuum tube 18, which sucks the burrs removed from the gaps of the cable cover 4 into the vacuum tube 18. Once inside the external vacuum cleaner, the subsequent cleaning steps of removing burrs can be automatically completed without manual collection, making the operation more convenient and avoiding the accumulation of burrs falling into the fixed shell 20, which would affect the subsequent burr removal work of the protective cover.

[0046] In one embodiment, two protruding rings 19 are fixedly connected to the periphery of the vacuum cleaner cylinder 18. The protruding rings 19 have several protrusions on their periphery. The side wall of the scraper 28 has two notches corresponding to the protruding rings 19. A fixed cylinder 29 is fixedly connected to the inner wall of the notch of the scraper 28. A striking block 37 is slidably connected to the inner wall of the fixed cylinder 29. A spring is fixedly connected between the striking block 37 and the inner wall of the fixed cylinder 29. The striking block 37 abuts against the protruding rings 19.

[0047] While the vacuum cleaner cylinder 18 rotates back and forth within a certain range, the convex ring 19 cooperates with the striking block 37, so that the striking block 37 can strike the convex ring 19 under the action of the spring. The convex ring 19 transmits the vibration to the vacuum cleaner cylinder 18, which can better prevent the burrs from clogging the vacuum cleaner cylinder 18's suction port.

[0048] In one embodiment, the positioning component 5 includes a placement frame 34, a clamping block 35, and a pressing positioning block 36. The clamping block 35 is fixedly installed on the placement frame 34. The clamping block 35 is made of elastic material and has elastic deformation capability. The shape of the clamping block 35 is adapted to the shape of the edge 2 on the periphery of the transparent cover 1. The pressing positioning block 36 is rotatably installed on the upper surface of the placement frame 34 through the bearing seat shaft. A coil spring is installed between the pressing positioning block 36 and the bearing seat.

[0049] The worker pulls down the positioning block 36, placing the transparent cover 1 of the protective cover upside down inside the clamping block 35. Since the transparent cover 1 has edges 2 around its perimeter, and the edges 2 are matched with the shape of the clamping block 35, the protective cover can be prevented from rotating axially during the deflashing process, making the protective cover more stable during the deflashing process. After the worker releases the hand, the positioning block 36 rotates under the action of the coil spring and abuts against the opening 3 of the protective cover, preventing the anti-slip cover from moving up and down during the deflashing process, further ensuring the stability of the protective cover processing. The protective cover of the present invention is compatible with the positioning component 5, which can achieve fast and stable positioning.

[0050] In one embodiment, two symmetrical side clamps 21 are fixedly connected to the periphery of the fixed shell 20. A pulley 26 is installed on the side wall of the side clamp 21 through a pin. The side clamp 21 is made of rigid material. The pulley 26 abuts against the clamping block 35, and there is pressure between the pulley 26 and the clamping block 35.

[0051] As the fixed shell 20 moves toward the protective cover, the pulley 26 on the side wall of the side clamping plate 21 contacts the clamping block 35, and the pulley 26 exerts a certain squeezing force on the clamping block 35 when in contact. Because the clamping block 35 has the ability to deform elastically, it can transmit pressure to the transparent cover 1 of the protective cover, so that the gap at the transparent cover 1 is in full contact with the scraper 27, thereby improving the scraper 27's effect of removing burrs.

[0052] The above embodiments disclose a composite surge arrester transparent protective cover and its processing technology. The specific working principle and process are as follows: S1: The worker pulls down the positioning block 36 and places the transparent cover 1 of the protective cover upside down in the clamping block 35. Since the transparent cover 1 has edges 2 on its periphery and the shape of the edges 2 matches the clamping block 35, the protective cover can avoid axial rotation during the deflashing process, making the protective cover more stable during the deflashing process. Compared with the traditional surge arrester protective cover, the protective cover of the present invention has edges 2 added on its periphery, which can better clamp the protective cover during the processing, making the processing process more stable. After the worker releases his hand, the positioning block 36 rotates under the action of the coil spring and abuts against the opening 3 of the protective cover, preventing the anti-slip cover from moving up and down during the deflashing process, and further ensuring the stability of the protective cover processing. The protective cover of the present invention is compatible with the positioning component 5 to achieve fast and stable positioning. S2: After the protective cover is installed, the motor 9 is started by the external controller. The motor 9 drives the lead screw 11 to rotate. The lead screw 11 drives the deflash removal component 6 on the slider 12 to move towards the protective cover position. The cable cover 4 part of the protective cover first enters the fixed shell 20. As the deflash removal component 6 continues to move forward, the scraper 28 in the fixed shell 20 scrapes off the deflashes in the gaps of the cable cover 4 part of the protective cover, and the scraper 27 scrapes off the deflashes in the gaps of the transparent shell 1 part of the protective cover. The scraper 27 has a T-shaped structure. S3: When the fixed shell 20 moves towards the protective cover, the pulley 2 33 inside the mounting block 30 abuts against the cable cover 4 of the protective cover, and under the action of the spring, the pulley 2 33 exerts pressure on the cable cover 4 of the protective cover, so that the inner wall of the gap at the position of the cable cover 4 can fully contact the scraper 2 28, thereby improving the scraper 2 28's effect of removing burrs. S4: When the fixed shell 20 moves towards the protective cover, the pulley 26 on the side wall of the side clamping plate 21 contacts the clamping block 35, and the pulley 26 exerts a certain squeezing force on the clamping block 35 when it contacts. Since the clamping block 35 has the ability to deform elastically, it can transmit pressure to the transparent cover 1 of the protective cover, so that the gap at the transparent cover 1 is in full contact with the scraper 27, thereby improving the scraper 27's effect of removing burrs. S5: When the fixed shell 20 moves towards the protective cover, the gear 22 meshes with the rack 10 and rotates. The gear 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the connecting rod engagement 24 to rotate. During the rotation of the connecting rod engagement 24, the slider 25 and the fixed shell 20 reciprocate on the guide rail 14 and the guide rail 25, so that the scraper 1 27 and the scraper 2 28 can perform high-frequency reciprocating motion to remove the flash, further improving the flash removal effect of the flash removal assembly 6. S6: Turn on the external vacuum cleaner. The vacuum cleaner creates negative pressure inside the vacuum tube 18, which can suck the burrs removed from the gaps of the cable cover 4 into the vacuum tube 18. After entering the external vacuum cleaner, the subsequent cleaning steps of removing burrs can be automatically completed without manual collection. The operation is more convenient and saves time. It also avoids the burrs removed from accumulating and falling into the fixed shell 20, which would affect the subsequent burr removal work of the protective cover. S7: While the fixed shell 20 is moving laterally, the guide cylinder 17 is moving laterally relative to the second guide rail 15. The sliding head 16 on the second guide rail 15 cooperates with the spiral track of the guide cylinder 17 and slides on the track, causing the guide cylinder 17 to rotate. The rotation of the guide cylinder 17 drives the suction port of the vacuum tube 18 to rotate. The range of rotation of the suction port can increase the suction range, making it easier for the burrs to be sucked into the vacuum tube 18. In addition, the rotation of the vacuum tube 18 is a periodic reciprocating rotation, which can reduce the situation of burrs clogging the suction port of the vacuum tube 18 to a certain extent and improve the cleaning and collection effect of the device on the removed burrs. S8: When the vacuum cleaner cylinder 18 rotates back and forth periodically within a certain range, the convex ring 19 cooperates with the striking block 37, so that the striking block 37 can strike the convex ring 19 under the action of the spring. The convex ring 19 transmits the vibration to the vacuum cleaner cylinder 18, which can better prevent the burrs from clogging the vacuum cleaner cylinder 18's suction port. S9: After the burrs on the protective cover are removed, start the motor 9 again to make the burr removal component 6 retract. The operator can then pull open the pressing positioning block 36 and remove the protective cover from the clamping block 35, thus realizing the automatic burr removal process of the protective cover.

[0053] The positioning component of this invention uses a clamping block made of elastic material that fits the edge, and is equipped with a pressing positioning block with a coil spring. The operator can quickly complete the placement and positioning of the protective cover. The pressing positioning block automatically abuts against the opening of the protective cover, effectively preventing it from moving up and down during processing. It has high positioning accuracy, is easy to operate, and greatly shortens the clamping time.

[0054] This invention enables rapid positioning of the protective cover, automated removal of burrs, and automatic collection and anti-clogging of burrs. The entire processing only requires workers to perform simple clamping and unloading operations, which greatly reduces the intensity of manual labor and labor costs.

Both the transparent housing (1) and the cable cover (4) are transparent structures and have an internal cavity adapted to the composite surge arrester. The cable cover (4) is fixedly connected to the side wall of the transparent housing (1). Both the transparent housing (1) and the cable cover (4) have openings that are easy to pry open. The transparent housing (1) has a ridge (2) around its perimeter to facilitate adaptation to the processing device and prevent movement during processing. The transparent housing (1) has an open opening (3) at its bottom.

2. A processing method for manufacturing the transparent protective cover of the composite surge arrester as described in claim 1, characterized in that, Includes the following steps: S1: Silicone raw rubber, reinforcing agent, structure control agent, vulcanizing agent and various functional additives are put into the mixing equipment according to the ratio. Through repeated kneading and mixing, the various additives are evenly dispersed in the silicone rubber to form the final compound for molding. S2: The mixed rubber compound is further thinned and rolled on a two-roll mill to plasticize and soften it, achieving the required softness and thickness for compression molding. The treated rubber compound is then cut into blanks of specific weight and shape for later use. S3: Place the cut rubber blank into the preheated metal mold cavity. After the mold is closed, vulcanize under high temperature and high pressure. The pressure makes the rubber fill every corner of the mold, and the high temperature triggers the vulcanization reaction, causing the linear silicone rubber molecular chains to cross-link into a three-dimensional network structure, changing from plastic to elastomer. S4: Place the molded and pre-trimmed protective cover into an oven and bake at a constant temperature of 200℃ for several hours; S5: After the product cools down, use a flash removal device to remove the flash generated during molding. Finally, conduct strict spot checks on appearance, dimensions and electrical performance. Only products that pass the checks can be packaged and put into storage.
