[0002] Insulators are the main body of the insulation of transmission lines, consisting of a metal core and sheds on the outside of the core. Their function is to suspend the conductors and keep them insulated from the towers and the ground. Insulators must withstand not only working voltage and overvoltage, but also the vertical load, horizontal load and tension of the conductors.

[0003] In the production process of composite insulators, the mixed silicone rubber is first rolled multiple times before use to expel gas and increase flexibility; then, it is cut to the appropriate size according to the amount of rubber required for the product; before vulcanization, the core rod is coated with a coupling agent to achieve better adhesion between the core rod and the silicone rubber bonding surface; the silicone rubber is wrapped around the outside of the core rod and die-cast using a die-casting mold.

[0004] After the composite insulator is formed, a thin connecting film is formed between adjacent sheds (such as...).

[0039] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0041] First, let's introduce the application scenarios of this application: Figure 1 The diagram shown is of a composite insulator after demolding, including the central metal core rod and the sheds located on the outside of the core rod. After the composite insulator is formed, a thin connecting film is formed between adjacent sheds (e.g., Figure 1 As shown in the image, the current method for handling the membrane is to tear it off manually.

[0042] like Figure 2 As shown, the present invention provides an adjustable combined insulator casting device, including an adjustable casting device and a unloading robotic arm 1 located on the discharge side of the adjustable casting device, and a processing box 2; the side of the processing box 2 is provided with a connecting membrane processing mechanism, which is used to remove the connecting membrane between the sheds and to blow the sheds; both sides of the processing box 2 are provided with a mandrel driving mechanism, which is used to clamp the mandrel on both sides and drive the mandrel to rotate around the axial direction; the execution end of the unloading robotic arm 1 is provided with a mandrel clamping mechanism; the mandrel clamping mechanism is used to clamp the mandrel on both sides and transfer the formed composite insulator from the adjustable casting device to the upper side of the processing box 2; after the mandrel clamping mechanism clamps and fixes the two sides of the composite insulator, it drives the composite insulator to rotate, and after the connecting membrane between the sheds comes into contact with the connecting membrane processing mechanism, it is knocked off by the connecting membrane processing mechanism and falls into the processing box 2.

[0043] The specific structure of the mandrel drive mechanism is as follows: Figure 3-4As shown, the mandrel drive mechanism includes a drive mounting ear 3 connected to the processing box 2 and a mandrel drive cylinder 4 fixed on the drive mounting ear 3. A U-shaped mandrel drive frame 5 is fixed on the push head of the mandrel drive cylinder 4. A mandrel drive motor 6 is installed inside the mandrel drive frame 5, and the motor shaft of the mandrel drive motor 6 is fixed to the mandrel drive plate 7. Several spring positioning pins 8 are provided on the inner side of the mandrel drive plate 7. When the unloading robotic arm 1 transfers the formed composite insulator to the upper side of the processing box 2 through the mandrel clamping mechanism, the push heads of the mandrel drive cylinders 4 on both sides of the processing box 2 extend, driving the mandrel drive plate 7 to move. The spring positioning pin 8 on the side contacts the end of the core rod; the spring positioning pin 8 has elastic extension and contraction characteristics, the inner spring positioning pin 8 is stuck in the keyway at the end of the core rod, and the outer spring positioning pin 8 surrounds the outside of the core rod; after clamping, the core rod drive motor 6 in the core rod drive frame 5 starts, and its motor shaft drives the core rod drive plate 7 to rotate, driving the core rod to rotate around its own axis; the sheds of the composite insulator rotate synchronously with the core rod, and the connecting membrane between the sheds comes into contact with the connecting membrane processing mechanism on the side of the processing box 2 during the rotation, is knocked off by the mechanism and falls into the processing box 2, realizing the automatic removal of the connecting membrane.

[0044] like Figure 3 , Figure 5 , Figure 6 As shown, the membrane treatment mechanism includes a spray mounting plate 9 connected to the treatment box 2. A spray treatment chamber 10 is provided on the side of the spray mounting plate 9, and the spray treatment chamber 10 has a single-sided opening structure. A spray switching cylinder 11 is provided on the side of the spray mounting plate 9, and the pusher of the spray switching cylinder 11 extends into the spray treatment chamber 10 and connects to the side of the spray striking component. The spray striking component includes a rectangular cavity structure main spray chamber 12, and a striking spray head 13 is provided on the side of the main spray chamber 12. The striking spray head 13 communicates with the interior of the main spray chamber 12. A cleaning channel 14 corresponding to the striking spray head 13 is opened on the side of the spray treatment chamber 10, and the striking spray head 13 and the cleaning channel 14 are slidably engaged. Figure 6 As shown, the lower side of the cleaning channel 14 is provided with flexible bristles 15. When the spray switching cylinder 11 retracts, the flexible bristles 15 can brush away the film and impurities adhering to the lower surface of the striking spray head 13. The striking spray head 13 has a rectangular cavity structure, and the front side of the striking spray head 13 has a wedge-shaped structure. Impurity spraying channels 16 are opened on both sides and the front side of the striking spray head 13. The impurity spraying channels 16 on both sides are used to spray the umbrella skirts on both sides of the striking spray head 13, and the impurity spraying channel 16 on the front side is used to spray the core rod axially to remove the film debris, release agent particles, etc. attached to it. An anti-sticking spraying channel 17 is opened on the lower side of the striking spray head 13. The lower side of the striking spray head 13 is used to strike the film between the umbrella skirts. Through the continuous spraying of the anti-sticking spraying channel 17, the film is prevented from adhering to the lower side of the striking spray head 13. Figure 5 , Figure 7 , Figure 8 As shown; the main jet chamber 12 has a threaded connection port on its side, and one side of the external gas pipeline 18 is connected to the threaded connection port; the other side of the external gas pipeline 18 has an annular sealing pipe 19; an internal gas pipeline 20 is slidably fitted inside the annular sealing pipe 19 (a rubber ring is provided inside the annular sealing pipe 19 to achieve a sliding seal), and one end of the internal gas pipeline 20 has a sliding switching head 21, which is slidably fitted inside the external gas pipeline 18 (a rubber ring is provided on the outside of the sliding switching head 21 to achieve a sliding seal); the internal gas pipeline 20 The other end extends out of the spray mounting plate 9 and is fixed to the spray mounting plate 9; a cleaning air pump 22 is provided on the upper side of the spray treatment chamber 10, and the air outlet of the cleaning air pump 22 is connected to the end flange of the internal gas pipeline 20 through a cleaning hose 23; the sliding switching head 21 is connected to the internal gas pipeline 20, and the cleaning air pump 22 can spray gas to the sliding switching head 21 through the internal gas pipeline 20; the sliding switching head 21 has a cylindrical cavity structure, and cleaning air jet holes 24 are provided on both outer edges of the sliding switching head 21; the sliding switching head 2 Sealing rings 25 are provided on the external gas pipes 18 on both sides of 1. The sealing rings 25 are used to block the cleaning jet holes 24. The external gas pipe 18 between the sealing rings 25 and the annular sealing pipe 19 is connected to the main pipe of the bristle cleaning diversion pipe 27 through a cleaning bellows 26 (the cleaning bellows 26 can be extended). The branch pipes of the bristle cleaning diversion pipe 27 are directly opposite the flexible bristles 15 on the lower side of the cleaning channel 14. The bristle cleaning diversion pipe 27 is fixed inside the blowing treatment chamber 10. When the sliding switching head 21 is connected to the sealing ring on the right side... When the ring 25 contacts, the cleaning jet hole 24 on the left side of the sliding switching head 21 is opened, and the airflow enters the main spray cavity 12 through the sealing ring 25 on the left side and blows towards the blow nozzle 13; the spray switching cylinder 11 retracts and drives the external gas pipeline 18 to slide to the right, the sliding switching head 21 contacts the sealing ring 25 on the left side, the cleaning jet hole 24 on the right side of the sliding switching head 21 is opened, and the airflow enters the cleaning corrugated pipe 26 through the gap between the sealing ring 25 on the right side and the internal gas pipeline 20, and blows air onto the bristle cleaning diversion pipe 27.

[0045] During operation, the membrane treatment mechanism achieves coordinated operation of impacting and removing the membrane between the composite insulator skirts and self-cleaning of components through the linkage of the spray switching cylinder 11 and the gas pipeline; in conjunction with the above connection relationship and the appendix to the instruction manual... Figure 9 The working principle of the membrane treatment mechanism is as follows:

[0046] When it is necessary to remove the membrane connecting the umbrella skirts, the blow-switching cylinder 11 extends its pusher, driving the blow-switching impact component to move outward of the blow-switching treatment chamber 10. The impact blow-switching head 13 on the side of the main blow-switching chamber 12 slides out along the cleaning channel 14. At this time, the external gas pipeline 18 moves synchronously with the blow-switching impact component, and the sliding switch head 21 contacts the right sealing ring 25, opening the cleaning air jet hole 24 on its left side. The cleaning air pump 22 starts, and high-pressure gas enters the internal gas pipeline 20 through the cleaning hose 23, and flows into the external gas pipeline 18 through the cleaning air jet hole 24 on the left side of the sliding switch head 21. Then it enters the main blowing chamber 12; the gas is ejected through multiple channels of the impact blowing head 13: the impurity blowing channels 16 on both sides blow the umbrella skirt surface, the impurity blowing channel 16 on the front side blows air along the core rod axis to remove the attached connecting membrane debris; the anti-sticking blowing channel 17 on the lower side continuously blows air to prevent the connecting membrane that has been knocked off from the impact from sticking to the lower surface of the impact blowing head 13; at the same time, the wedge-shaped structure on the front side of the impact blowing head 13 directly contacts the connecting membrane between the umbrella skirts, and with the cooperation of the composite insulator rotation (driven by the core rod drive mechanism), knocks the connecting membrane off into the processing box 2.

[0047] Once the umbrella skirt area is cleaned, the blow-off switching cylinder 11 retracts, and its pusher pulls the external gas pipe 18 to the right. The sliding switching head 21 then engages with the left sealing ring 25, and the right cleaning jet hole 24 opens. The airflow is redirected through the cleaning corrugated pipe 26 into the bristle cleaning diversion pipe 27, and blows from the diversion pipe to the flexible bristles 15 on the lower side of the cleaning channel 14, removing the impurities adhering to the base of the bristles. During the retraction of the blow-off head 13, the flexible bristles 15 mechanically scrape the lower surface, and the remaining adhering substances are carried away by the airflow and bristles, achieving self-cleaning.

[0048] The beneficial effects of membrane treatment facilities are reflected in:

[0049] The membrane treatment mechanism achieves switching between two working modes: "umbrella skirt-core rod blowing" and "brush self-cleaning" through the air path reversal of the "sliding switching head 21-sealing ring 25". First, the wedge-shaped structure of the impact blowing head 13 and the multi-directional blowing channel work together to efficiently remove the membrane through mechanical impact and thoroughly clean the impurities on the surface of the umbrella skirt, core rod and impacting parts through gas blowing, solving the problem of residual debris in traditional single impact. Second, the cooperative design of the sliding switching head 21 and the sealing ring 25 uses the action of the blowing switching cylinder 11 to synchronously switch the gas path, completing the mode conversion between "impact blowing" and "brush cleaning" without additional driving components, with a compact structure and strong linkage. Third, the dual anti-stick design of the anti-stick blowing channel 17 and the flexible bristles 15 prevents the membrane from sticking to the impacting parts, while keeping the bristles clean through gas back-blowing, ensuring stable cleaning effect during long-term use.

[0050] After cleaning the connecting membrane between the sheds of the composite insulator, it is also necessary to brush the connecting membrane at the end of the core rod; such as Figure 3 As shown, the processing box 2 has core rod scraping mechanisms on both sides inside, and the core rod scraping mechanisms correspond to the ends of the core rods on both sides of the composite insulator; as Figure 10-11 As shown, the mandrel scraping mechanism includes a scraping base frame 28 with an H-shaped cross-section. The lower side of the scraping base frame 28 is fixed to the bottom of the processing box 2. Scraping pressure shafts 29 are slidably fitted at both ends of the upper side of the scraping base frame 28. A scraping shaft connecting plate 30 is provided on the outer side of the scraping pressure shaft 29, and an arc-shaped scraping plate 31 is provided on the inner side of the scraping pressure shaft 29. Steel wire bristles 32 are provided inside the scraping plate 31. The steel wire bristles 32 are used to simultaneously brush the connecting membrane at the end of the mandrel when the composite insulator rotates to remove the connecting membrane of the shed. A scraper spring 33 passes through the scraper pressure shaft 29 between the scraper plate 31 and the scraper 8. The scraper spring 33 is used to force the scraper plate 31 to slide inward, so that the wire bristles 32 contact the end of the mandrel. A polishing cylinder 34 is provided on the horizontal plate of the scraper base frame 28. The push head of the polishing cylinder 34 extends upward through the scraper base frame 28 and is fixed to the arc-shaped cross-section polishing plate 35. A polishing cloth 36 is adhered to the upper side of the polishing plate 35. The polishing cloth 36 is used to polish the end of the mandrel after the wire bristles 32 have finished brushing the end of the mandrel with the film. Figure 11 As shown, the scraper base 28 has an L-shaped conversion rope channel 37. One end of the conversion rope 38 is connected to the side of the scraper plate 31, and the other end of the conversion rope 38 is fixed to the lower side of the polishing plate 35.

[0051] The working process of the core rod scraping mechanism is as follows: The composite insulator is driven to rotate, and the connecting membrane between the skirts is first peeled off by the high-speed airflow of the blower head 13; at the same time, the polishing cylinder 34 retracts, and the scraping brush pressure shaft 29 drives the scraping brush plate 31 to slide inward under the thrust of the scraping brush spring 33. The steel wire bristles 32 elastically press against the end of the core rod, and continuously scrape the connecting membrane remaining on the end face of the core rod as the insulator rotates; when the connecting membrane on the end face of the core rod is cleaned, the polishing cylinder 34 extends, the pusher drives the polishing plate 35 to rise, and the conversion rope 38 is pulled to make the scraping brush plate 31 move outward against the scraping brush spring 33; the polishing cloth 36 adheres to the end face of the core rod and completes the polishing while the insulator continues to rotate; by arranging the core rod scraping mechanism in the processing box 2, the present invention realizes the synchronous processing of the skirts and the end of the core rod.

[0052] Figure 12The diagram shows a schematic of the mandrel clamping mechanism. The mandrel clamping mechanism includes a C-shaped unloading base 39, on which an unloading shaft 40 is vertically mounted.

The inner side of the mold channel steel 53 is provided with pins for locking the mold. The two sides of the forming mold 52 have locking grooves 54 corresponding to the pins. The forming mold 52 is locked in the mold channel steel 53 and fixed by bolts.

[0054] Composite insulators are die-cast using an adjustable casting device. During the die-casting process, the mandrel can easily become stuck in the molding die 52, and is usually removed using a pry bar. To solve this problem, such as... Figure 13 , 15As shown, a mandrel ejection mechanism is provided on the casting platform 44. The mandrel ejection mechanism includes an ejection slide shaft 55, the two sides of which are fixed to the upper side of the casting platform 44 via bearing seats 56. An ejection sleeve 57 is slidably fitted on the ejection slide shaft 55, and the die-casting lower slide plate 50 is fixed to the upper side of the ejection sleeve 57. An ejection cylinder 58 is fixed to the side of the casting platform 44 via a cylinder frame 89. The push head of the ejection cylinder 58 is fixed to the side of the die-casting lower slide plate 50 via a connecting ear 59. The push head of the ejection cylinder 58 extends and retracts, causing the die-casting lower slide plate 50 to slide along the ejection slide shaft 55. Upper support fixing plates 60 are provided on the left and right sides of the die-casting lower slide plate 50. An upper support shaft 61 is slidably fitted on the upper support fixing plate 60. An upper support head 62 is provided on the upper side of the upper support shaft 61. The upper support head 62 has a groove corresponding to the end of the mandrel. An upper support connecting plate 63 is provided on the lower side of the upper support shaft 61. The upper support connecting plates on both sides are connected to the upper support connecting plate 64. An upper support main plate 64 is provided between the plates 63, and the upper support connecting plate 63 and the upper support main plate 64 are connected by an upper support connecting column 65; the die-casting lower slide plate 50 has grooves on both sides, and the upper support connecting column 65 slides in the grooves on both sides of the die-casting lower slide plate 50; an upper support wheel 66 is provided on the lower side of the upper support connecting plate 63; driving vertical plates 67 are provided opposite each other on the casting platform 44, and a Z-shaped driving folding plate 68 is provided between the driving vertical plates 67, and the upper support wheel 66 contacts and engages with the driving folding plate 68; an upper support return spring 69 passes through the upper support shaft 61 between the upper support connecting plate 63 and the upper support fixing plate 60; the upper support return spring 69 is used to force the upper support wheel 66 to contact the driving folding plate 68; when the die-casting lower slide plate 50 moves to the lower side of the die-casting upper slide plate 49, the groove of the upper support head 62 is lower than the axis of the forming mold 52, and when the die-casting lower slide plate 50 moves out, the upper support head 62 pushes the die-cast composite insulator upward.

[0055] Based on the connection between the casting platform 44 and the mandrel ejection mechanism, its working process is as follows:

[0056] During the die-casting stage, the ejector cylinder 58 is in the retracted position, and the die-casting lower slide plate 50 is located directly below the die-casting upper slide plate 49. At this time, the upper support roller 66 is located in the low horizontal section of the drive folding plate 68, and the upper support head 62 is lower than the demolding surface of the forming mold 52. After die-casting is completed, the ejector cylinder 58 extends, and the pusher head pushes the die-casting lower slide plate 50 to move outward as a whole. Under the continuous action of the upper support return spring 69, the upper support roller 66 always stays close to the drive folding plate 68. When it slides past the rising slope of the folding plate... The upper support roller 66 is forced to rise, and through the upper support connecting column 65, upper support connecting plate 63, and upper support shaft 61, the upper support head 62 moves vertically upward. The end of the core rod in the groove is simultaneously lifted, and the composite insulator is completely removed from the forming mold 52, completing the demolding without pry bar. Then the lifting cylinder 58 continues to extend outward, and the upper support roller 66 enters the high horizontal section of the folded plate and remains in the raised state. After the part is removed by manual or robotic arm, the cylinder retracts in the opposite direction, and the components are reset in the reverse order, ready for the next round of die casting.

[0057] When the mandrel becomes stuck with the molding die 52, directly lifting the mandrel out via the rigidly connected upper support head 62 can easily cause hard contact damage to the mandrel or the molding die 52; to solve this problem, such as Figure 16 As shown; the upper support head 62 is flexibly fitted with the upper support shaft 61. The lower side of the upper support head 62 is provided with a constriction groove 70. The upper part of the upper support shaft 61 is slidably fitted in the constriction groove 70 (the upper support shaft 61 has an anti-disengagement structure and will not disengage from the constriction groove 70). A buffer spring 71 is provided between the upper side of the upper support shaft 61 and the bottom of the constriction groove 70. The buffer spring 71 has a large stiffness coefficient and can lift out the clamped mandrel. When the mandrel is jammed with the forming mold 52, the buffer spring 71 is compressed and then removed by prying it up on one side with a pry bar.

[0058] After the formed composite insulator is lifted out by the core rod lifting mechanism, it needs to undergo natural cooling and air cooling; such as Figure 17 As shown, the adjustable casting device has a small robotic arm 72 on the discharge side, and the execution end of the small robotic arm 72 is equipped with an air-cooled upper support mechanism; the air-cooled upper support mechanism is used to air-cool the formed composite insulator; as shown Figure 18 As shown, the air-cooled upper support mechanism includes an L-shaped cross-section air-cooled base frame 73; the air-cooled base frame 73 is equipped with an air-cooled pump 74 and an air-cooled cavity 75, and the air outlet of the air-cooled pump 74 is connected to the interior of the air-cooled cavity 75 through an air-cooled hose 76; the air-cooled pump 74 sprays airflow into the air-cooled cavity 75 to cool the formed composite insulator; as shown Figures 19-20As shown, the air-cooled cavity 75 is a cylindrical cavity structure with an opening on the lower side. The lower side of the air-cooled cavity 75 is fixed to the upper support ring 78 via an air-cooled corrugated pipe 77. An air-cooled rotating plate 79 is rotatably fitted inside the upper support ring 78, and the air-cooled rotating plate 79 is provided with air spray holes 80. An air-cooled drive motor 82 is mounted on the upper side of the air-cooled cavity 75 via a motor bracket 81. The motor shaft of the air-cooled drive motor 82 is fixed to one end of the rotating column 83 via a coupling, and an air-cooled ring frame 84 is fixed to the other end of the rotating column 83. The ring frame 84 is a frame structure. A linkage column 85 is slidably fitted onto the lower side of the air-cooled ring frame 84. The lower side of the linkage column 85 is fixed to the upper side of the air-cooled rotating plate 79. The upper side of the linkage column 85 has an anti-detachment structure to prevent it from coming off the air-cooled ring frame 84. An air-cooled return spring 86 passes through the linkage column 85 between the air-cooled ring frame 84 and the air-cooled rotating plate 79. An active pull ring 87 is provided on the upper side of the air-cooled ring frame 84. The lower side of the active pull ring 87 is connected to one end of a pulling rope 88. The other end of 88 passes through the anti-detachment structure on the upper side of the air-cooled ring frame 84 and the linkage column 85 (the upper side of the air-cooled ring frame 84 has a channel that allows the rope 88 to pass through); the upper side of the air-cooled cavity 75 is provided with an n-shaped cross-section cylinder frame 89, and a linkage cylinder 90 is provided on the cylinder frame 89. The push head of the linkage cylinder 90 passes downward through the cylinder frame 89 and is fixed to the linkage plate 91. Two linkage shafts 92 are provided opposite each other on the lower side of the linkage plate 91. The linkage shafts 92 are slidably engaged with the upper side of the air-cooled cavity 75. An electromagnet 93 is fixed at the lower end of 92; the air-cooled ring frame 84 and the air-cooled rotating plate 79 are rotated as a whole by the air-cooled drive motor 82, thereby changing the relative position of the air spray holes 80 and spraying and cooling the composite insulator after molding; when the core rod and the molding mold 52 are stuck, the electromagnet 93 is used to attract the active pull ring 87, which pulls the upper support ring 78 and the air-cooled rotating plate 79 to move upward. The electromagnet 93 releases the active pull ring 87, and the air-cooled rotating plate 79 strikes the core rod upward on one side.

[0059] The working process of the air-cooled top support mechanism is as follows:

[0060] After the core rod lifting mechanism lifts the formed composite insulator horizontally into place, the small robotic arm 72 swings, causing the air-cooled lifting mechanism to move near the composite insulator; compressed air enters the air-cooling chamber 75 through the air-cooling hose 76, and then passes through the air-cooling rotating plate 79 to form a directional airflow, which uniformly cools the outer surface of the insulator; the air-cooling drive motor 82 drives the air-cooling ring frame 84, the linkage column 85 and the air-cooling rotating plate 79 to rotate synchronously through the rotating column 83, and the air-cooling nozzle 80 sweeps relative to the circumference of the insulator.

[0061] When the mandrel gets stuck in the mold and the insulator fails to completely demold, the system switches to the striking mode. The linkage cylinder 90 extends, and the linkage shaft 92 pushes the electromagnet 93 downward to above the active pull ring 87. The electromagnet 93 is energized and attracts the active pull ring 87. Then, the linkage cylinder 90 retracts, and the air-cooled rotating plate 79 and the upper support ring 78 are pulled upward along the corrugated pipe by the rope 88. The small robotic arm 72 swings and moves the air-cooled upper support mechanism to the lower end of the mandrel on one side of the composite insulator. The distance between the air-cooled rotating plate 79 and the mandrel is less than the retraction distance of the air-cooled rotating plate 79. The electromagnet 93 is instantly de-energized to release the active pull ring 87. The air-cooled rotating plate 79 is quickly thrust downward under the action of the air-cooled return spring 86, and its lower surface directly strikes the end of the mandrel, generating an upward impact demolding force. If the first strike is unsuccessful, the above actions can be repeated until the mandrel is loosened.

[0062] The beneficial effects of the air-cooled top support mechanism are:

[0063] This invention integrates air cooling and demolding assistance functions into the same air-cooled upper support mechanism; during the air cooling stage, rotating air jets 80 are used to achieve uniform circumferential cooling of the insulator; during the striking stage, the transient linkage of "electromagnet 93 - pulling rope 88 - bellows" amplifies the linear displacement of the cylinder into the rapid impact stroke of the air-cooled rotating plate 79; the striking structure of the linkage cylinder 90 and electromagnet 93 forms a jamming emergency handling mechanism, realizing automatic striking demolding, reducing operational risks and protecting the mandrel and mold from hard damage.
