Description

Technical Field

[0001] This invention relates to the field of insulator molding technology, and specifically to a vulcanization molding apparatus for composite insulator skirts. Background Technology

[0002] Composite insulators are commonly used insulating devices in power transmission and transformation projects. Their core structure includes a core rod that bears mechanical loads and sheds that provide insulation, weather resistance, and anti-pollution functions. Vulcanization molding is a key process for combining silicone rubber sheds and core rods to form insulators. In injection vulcanization, the rubber compound is plasticized by the screw of the injection molding machine and then injected into the closed mold cavity under high pressure. At the same time, the mold is heated, and the rubber compound quickly fills the cavity and completes vulcanization.

[0003] Most existing vulcanization molding equipment lacks built-in loading and unloading functions. To facilitate this, a track frame is typically installed outside the equipment. The track frame feeds the mandrel between the upper and lower molds of the vulcanization molding equipment, and after the insulator is vulcanized, it is ejected by the track frame, thus facilitating insulator loading and unloading. However, the track frame itself is quite long and bulky, and cannot be easily stored. While facilitating loading and unloading, it also increases the overall footprint of the equipment, resulting in excessive space occupancy. This leads to significant waste of space resources, especially when the equipment is idle, and increases operating costs. Summary of the Invention

[0004] This invention provides a composite insulator skirt vulcanization molding device, which aims to solve the problem in related technologies that the track frame itself is already large in length and volume and cannot be well stored, which, while facilitating the loading and unloading of equipment, also increases the overall footprint of the equipment.

[0005] The composite insulator skirt vulcanization molding device of the present invention includes a base, an upper mold base and a lower mold base are provided on the base, and the lower mold base can be raised and lowered on the base. A plate is provided inside the lower mold base, and a wing plate is provided on the plate. The wing plate can be lowered relative to the plate when the lower mold base is close to the upper mold base, and raised relative to the plate when the lower mold base is far away from the upper mold base.

[0006] The lower mold base is equipped with a guide rail. The bottom of the plate is equipped with two pillars located inside the lower mold base, and the bottom ends of the pillars are set on the guide rails, which can slide along the guide rails and rotate when they move to the end of the guide rails. A ring is provided on one side of the pillar, and the ring can slide inside the lower mold base after the lower mold base descends to a certain height, pushing the pillar to slide along the guide rails. A connecting rod is provided between the two pillars on one side of the guide rails.

[0007] Preferably, the top of the lower mold base is provided with an interconnected receiving cavity and a connecting groove. The receiving cavity is opened along the length direction of the lower mold base, and the plate and the support are both located in the receiving cavity.

[0008] Preferably, the plate is fixedly mounted with a frame, the wing plate is located directly above the connecting groove and is slidably assembled in the frame, and the bottom of the upper mold base has a slot located directly above the frame.

[0009] Preferably, the bottom end of the frame is provided with a base, the inside of the base is rotatably fitted with a guide shaft, and the top end of the guide shaft is rotatably fitted with the top end of the frame. The wing plate is sleeved on the outside of the guide shaft, and a torsion spring is provided between the guide shaft and the base.

[0010] Preferably, the guide shaft has a spiral groove on its outer side, and a protrusion extending into the spiral groove is fixedly installed on the wing plate.

[0011] Preferably, both support columns are composed of a cylinder and a pneumatic cylinder. The pneumatic cylinder is located inside the cylinder, and its telescopic end is rotatably fitted with a rotating seat fixed to the bottom of the plate. The cylinders of the two support columns are rotatably fitted to both ends of the connecting rod, respectively.

[0012] Preferably, the guide rail is provided with a circular groove and a transverse groove. There are three transverse grooves distributed at equal intervals, which are respectively located at both ends and the middle of the circular groove. Guide blocks are fixedly installed on the end sides of both cylinders. The guide blocks are square blocks whose shape and size are adapted to the circular groove and the transverse groove. The guide blocks on the two cylinders are located in two adjacent transverse grooves, which can rotate in the transverse groove. After the guide blocks rotate to be parallel to the circular groove, they can slide into the circular groove.

[0013] Preferably, a drive groove is formed on the side wall of the receiving cavity along its length direction, a drive shaft is rotatably mounted inside the drive groove, and a spiral guide groove is formed on the outside of the drive shaft. A ring sleeve is fitted outside the drive shaft and slidably mounted in the guide groove. A push rod is fixedly installed on the ring sleeve. A sliding groove is formed on the side wall of the cylinder along its length direction, and the end of the push rod away from the ring sleeve is slidably mounted in the sliding groove.

[0014] Preferably, a transmission gear is coaxially fixed to the end of the drive shaft, and a transmission rack is vertically fixed to the base, which can mesh with the transmission gear when it descends.

[0016] Beneficial effects:

[0017] In use, this invention automatically demolds the insulators by raising the wing plates during the separation of the forming frame. By adjusting the material rack, the formed insulators are automatically fed between the upper and lower mold bases as the lower mold base descends, improving insulator unloading and eliminating the need for manual handling. When the lower mold base is raised, new insulator core rods are automatically fed between the upper and lower mold bases to facilitate the next round of vulcanization molding of the insulator skirts. This improves insulator core rod loading, increases insulator processing efficiency, and ensures convenient loading and unloading. Simultaneously, the material rack enters the receiving cavity for storage, improving internal space utilization, reducing the equipment's footprint, and effectively lowering equipment costs. Especially when the equipment is idle, it significantly reduces its size. Attached Figure Description

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1 to 8 As shown, the composite insulator skirt vulcanization molding apparatus of the present invention includes a base 10, a molding frame 20, a material rack 30, a demolding component 40, a flipping component 50, a guiding component 60, a driving component 70, and a transmission component 80. The molding frame 20 is disposed on the base 10 and can be opened and closed for vulcanization molding of the insulator skirt. The material rack 30 is disposed inside the molding frame 20 for supporting the insulator core rod. The demolding component 40 is disposed on the material rack 30 and can demold the insulator after the molding frame 20 is opened. The flipping component 50, the guiding component 60, and the driving component 70 are all located inside the molding frame 20. The transmission component 80 is disposed outside the molding frame 20 and can drive the driving component 70 to operate during the opening and closing of the molding frame 20, causing the flipping component 50 to operate along the guiding component 60, feeding the material rack 30 into or out of the molding frame 20 for loading and unloading.

[0030] refer to Figure 1 and Figure 2 A guide rod 11 is vertically fixed on the base 10, and a hydraulic column 12 is provided in the middle of the base 10.

[0031] refer to Figure 1 and Figure 2The forming frame 20 consists of an upper mold base 21 and a lower mold base 22. The upper mold base 21 and the lower mold base 22 are arranged opposite each other above the base 10 and are used for the installation of the upper and lower mold plates, respectively. The upper mold base 21 is fixedly installed on the top of the guide rod 11, and the lower mold base 22 is fixedly installed on the top of the hydraulic column 12. It can be lifted by the push of the hydraulic column 12 and attached to the upper mold base 21 from below, so that the upper and lower mold plates can be closed. A sliding sleeve 221 is fixedly installed on the side wall of the lower mold base 22, and the sliding sleeve 221 is slidably assembled on the outside of the guide rod 11, so that the guide rod 11 can limit and guide the lower mold base 22.

[0032] refer to Figure 3 , Figure 4 as well as Figure 7 The top of the lower mold base 22 is provided with a receiving cavity 222 and a connecting groove 223 that are interconnected. The receiving cavity 222 is opened along the length direction of the lower mold base 22. There are two connecting grooves 223 located at both ends of the lower mold base 22. A drive groove 224 is opened on the side wall of the receiving cavity 222 along its length direction for mounting the drive assembly 70.

[0033] refer to Figure 3 as well as Figure 5 The material rack 30 includes a plate 31, a frame 32, and a wing plate 33. The plate 31 is disposed inside the receiving cavity 222. The frame 32 has two symmetrically fixed ends to the plate 31. The wing plate 33 is located directly above the connecting groove 223 and is slidably disposed inside the frame 32 for supporting the insulator core rod. The wing plate 33 can slide up and down inside the frame 32 and enter the connecting groove 223 during the downward movement, so that the insulator core rod enters the upper and lower molds, and then the insulator skirt is injection vulcanized. The bottom of the upper mold base 21 has a slot 211 located directly above the frame 32, so that after the upper mold base 21 and the lower mold base 22 are combined, the frame 32 can be inserted into the slot 211.

[0034] refer to Figure 3 as well as Figure 8The demolding assembly 40 includes a base 41, a guide shaft 42, and a torsion spring 43. The base 41 is located at the bottom end of the frame 32. The guide shaft 42 is rotatably mounted inside the base 41, and its top end is rotatably mounted at the top end of the frame 32. The wing plate 33 is sleeved on the outside of the guide shaft 42, and can drive the guide shaft 42 to rotate when sliding within the frame 32, and can also slide within the frame 32 as the guide shaft 42 rotates. The torsion spring 43 is located between the guide shaft 42 and the base 41, so that... When the upper mold base 21 and the lower mold base 22 are closed to perform the mold closing of the upper and lower mold plates, the frame 32 is inserted into the slot 211. The upper mold base 21 presses the wing plate 33 down in the frame 32, which in turn drives the guide shaft 42 to rotate and cause the torsion spring 43 to store energy. When the upper and lower mold plates are opened, as the lower mold base 22 moves away from the upper mold base 21, the wing plate 33 gradually loses its force. The torsion spring 43 drives the guide shaft 42 to rotate and reset, and drives the wing plate 33 to rise in the frame 32, automatically demolding the insulator.

[0035] The guide shaft 42 has a spiral groove 421 on its outside. A protrusion 331 extending into the spiral groove 421 is fixedly installed on the wing plate 33. When the wing plate 33 descends, the protrusion 331 slides along the spiral groove 421, thereby pushing the guide shaft 42 to rotate. When the guide shaft 42 rotates back to its original position, the spiral groove 421 pushes the protrusion 331 to lift and reset the wing plate 33, so as to facilitate the demolding operation of the insulator.

[0036] refer to Figure 3 and Figure 5 The flipping assembly 50 includes a support column 51, a rotating seat 52, and a connecting rod 53. There are two support columns 51, both of which are disposed in the receiving cavity 222 and can rotate and slide within the receiving cavity 222. The rotating seat 52 is rotatably disposed at the top of the support column 51 and fixed to the plate 31. The connecting rod 53 is disposed between the two support columns 51 to limit the distance between the two support columns 51, so that when the two support columns 51 rotate and slide within the receiving cavity 222, they can drive the plate 31 to rise, fall, and move.

[0037] Both support columns 51 are composed of a cylinder 511 and a cylinder 512. The bottom end of the cylinder 511 is rotatably mounted on the end of the connecting rod 53. The cylinder 512 is located inside the cylinder 511, and its telescopic end is rotatably connected to the rotating seat 52, so that the support distance of the support column 51 on the plate 31 can be adjusted by the telescopic movement of the cylinder 512, so as to better remove the plate 31 and the insulator from the forming frame 20.

[0038] refer to Figure 3 as well as Figure 7The guide assembly 60 includes a guide rail 61 and a guide block 62. The guide rail 61 is laterally disposed in the lower mold base 22 on one side of the connecting rod 53 and is connected to the receiving cavity 222. The guide block 62 is fixedly installed on the end side of the cylinder 511, with its end away from the cylinder 511 disposed in the guide rail 61. It can slide along the guide rail 61 and rotate after moving to a certain position.

[0039] The guide rail 61 is provided with a circular groove 611 and a transverse groove 612. There are three transverse grooves 612 that are equidistantly distributed and are respectively located at both ends and the middle of the circular groove 611. The guide block 62 is a square block whose shape and size are adapted to the circular groove 611 and the transverse groove 612. The guide blocks 62 on the two cylinders 511 are respectively located in two adjacent transverse grooves 612. They can rotate in the transverse groove 612. After the guide block 62 rotates to be parallel to the circular groove 611, it can slide into the circular groove 611 and slide laterally along it until it enters the adjacent circular groove 611. It can then rotate again.

[0040] refer to Figure 3 and Figure 7 The drive assembly 70 includes a drive shaft 71, a ring 72, and a push rod 73. The drive shaft 71 is rotatably mounted inside the drive groove 224, and a spiral guide groove 711 is provided on the outside of the drive shaft 71. The ring 72 is fitted on the outside of the drive shaft 71 and is slidably mounted in the guide groove 711. The push rod 73 is fixed to the outer wall of the ring 72. A sliding groove 513 is provided on the side wall of the cylinder 511 along its length direction, and the end of the push rod 73 away from the ring 72 is slidably mounted in the sliding groove 513. When the drive shaft 71 rotates, it pushes the ring 72 to move in the drive groove 224 through the guide groove 711, and the push rod 73 pushes the cylinder 511 to move. After the guide block 62 enters the transverse groove 612 of the guide rail 61, the push rod 73 slides in the sliding groove 513, pushing the cylinder 511 to rotate.

[0041] refer to Figure 1 , Figure 2 as well as Figure 7 The transmission assembly 80 includes a transmission gear 81 and a transmission rack 82. The transmission gear 81 is located on the side of the lower mold base 22 and is coaxially fixed to the end of the drive shaft 71. The transmission rack 82 is vertically fixed on the base 10 and can mesh with the transmission gear 81 when the lower mold base 22 descends, thereby driving the transmission gear 81 to rotate.

[0042] Working principle: The wing plate 33 supports both ends of the insulator core rod. The hydraulic column 12 pushes the lower mold base 22 to rise, so that it merges with the upper mold base 21. When the frame 32 is raised and inserted into the slot 211 in the upper mold base 21, the upper mold base 21 will block the wing plate 33, so that the wing plate 33 descends in the frame 32 and finally enters the connecting groove 223, so that the insulator core rod enters between the merged upper and lower molds for vulcanization molding of the insulator skirt. When the wing plate 33 descends in the frame 32, the protrusion 331 slides in the spiral groove 421 to push the guide shaft 42 to rotate, so that the torsion spring 43 stores energy.

[0043] The lower mold base 22 descends and separates from the upper mold base 21 to open the mold. The wing plate 33 is no longer obstructed by the upper mold base 21. The torsion spring 43 drives the guide shaft 42 to rotate, pushing the wing plate 33 to rise within the frame 32, pushing the insulator out of the lower mold plate. Then, the transmission rack 82 meshes with the transmission gear 81 that follows the descent of the lower mold base 22, driving the drive shaft 71 to rotate. The guide groove 711 pushes the ring sleeve 72 to move within the drive groove 224. The push rod 73 pushes the cylinder 511, causing the guide block 62 to rotate within the circular groove 611 of the guide rail 61, allowing the plate 31 to move with the formed insulator. When the guide block 62 rotates to be parallel to the circular groove 611, ... Push rod 73 pushes the slide into the circular groove 611, slides laterally along it, and drives plate 31 and insulator to move laterally synchronously. When guide block 62 enters the adjacent transverse groove 612, support column 51 stops moving and starts to rotate under the push of push rod 73. With the extension of cylinder 512, it pushes plate 31 to move forward. Finally, the insulator is sent out between upper mold base 21 and lower mold base 22, and the insulator can be unloaded. When lower mold base 22 is lifted, transmission gear 81 rotates in the opposite direction, so that plate 31 can be reset and enter receiving cavity 222, and new insulator core rod is sent into forming frame 20 for processing of the next set of insulators.

[0044] In this invention, the insulator is automatically demolded when the forming frame 20 separates by lifting the wing plate 33. By adjusting the material rack 30, the formed insulator is automatically fed out between the upper and lower mold bases 21 and 22 when the lower mold base 22 descends, thus improving the insulator unloading process and eliminating the need for manual handling. When the lower mold base 22 is lifted, a new insulator core rod is automatically fed between the upper and lower mold bases 21 and 22 to facilitate the vulcanization molding of the insulator skirts for the next round of operations. This improves the insulator core rod loading process, increases insulator processing efficiency, and ensures convenient loading and unloading. Simultaneously, the material rack 30 enters the receiving cavity 222 for storage, improving the integrated control effect between components, enhancing the internal space utilization of the equipment, reducing the equipment's footprint, and effectively reducing equipment costs. Especially when the equipment is idle, it significantly reduces its size.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
