Description

Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, and specifically relates to a new type of flat vulcanizing machine adapted to the intermediate joint of high-voltage cables. Background Technology

[0002] Currently, the main production equipment for high-voltage cable intermediate joints is a horizontal mold closing machine with horizontal mold closing. Its workflow is as follows: after the product mold core is placed into the mold → the moving template moves to close the mold → the pump pump pumps in the specified amount of rubber material into the mold → the mold closing cylinder pressurizes → the product vulcanizes → after vulcanization, the mold closing cylinder resets → the moving template moves to open the mold → the top crane / hoist lifts the mold core out → the worker uses tools to separate the product from the mold core.

[0003] Products manufactured using this equipment have a vertical mold parting surface. Due to the special nature of high-voltage cable joints—the cable joint is cylindrical, conductive in the middle and insulated on the outside—a vertical parting surface results in the parting line being on the surface of the insulation layer. This leads to a lower structural strength compared to products with a parting line in the wire diameter direction, and also lower explosion-proof performance. Furthermore, the demolding process is cumbersome, requiring manual lifting of the product and mold core together, placing the product on a specialized fixture, and using specialized tools to remove it.

[0004] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0038] Please see Figure 1-11 As the first embodiment of this utility model:

[0039] A novel flat vulcanizing machine adapted to high-voltage cable intermediate joints includes: a vulcanizing machine frame 100, the vulcanizing machine frame 100 including a base plate 101 and a frame 105, and a lower seat assembly 400 fixedly installed on the front side above the base plate 101.

[0040] A mold opening assembly 500 is fixedly installed on the rear side above the base plate 101. A middle seat assembly 200 is provided above the lower seat assembly 400, and an upper seat assembly 300 is provided above the middle seat assembly 200. The middle seat assembly 200 includes a middle seat 201, a mold locking cylinder 202, a mold lifting cylinder 204, an upper lifting beam 205, and a lifting rod 206. The mold locking cylinder 202 is fixedly connected to the middle position above the middle seat 201.

[0041] A set of lifting cylinders 204 are fixedly connected to the front and rear sides above the middle seat 201.

[0044] A pad mounting plate 211 is fixedly connected to the outside of the mold locking cylinder 202, and a middle seat pad 210 is fixedly connected above the mold locking cylinder 202. The lifting rods 206, which are set in opposite directions, are raised and lowered synchronously via the synchronous rotating shaft 209, and the lifting power is provided by the mold lifting cylinder 204.

[0045] A set of quick mold closing cylinders 306 are connected through both the left and right sides of the upper seat 301. An upper seat pad 307 is fixedly provided in the middle of the lower part of the upper seat 301, and a pad mounting seat 305 is provided below the upper seat pad 307.

[0046] Below the upper seat 301, there is also a pad guide rail 303 for assisting the movement of the upper seat pad 307. A connecting plate 304 is fixedly connected to the front side of the pad mounting seat 305, and a set of pad cylinders 302 are fixedly connected to both the left and right sides of the pad mounting seat 305.

[0047] A set of uprights 402 is connected through each of the four corners of the lower base 401. A set of mold moving guide rails 404 is provided on the left and right sides of the uprights 402 near the center of the lower base 401. A pneumatic limit seat 405 is fixedly installed at the rear end of the side of the mold moving guide rail 404 away from the center of the lower base 401.

[0048] A mold-moving slide plate 406 is provided above the two sets of mold-moving guide rails 404 on the left and right. A mold-moving cylinder 403 is fixedly connected to the front side of the mold-moving slide plate 406. When the mold-moving slide plate 406 moves backward, it is held and limited by the pneumatic limit seat 405 at the first station and the second station.

[0049] The mold opening assembly 500 includes a mounting plate 501, a screw connecting plate 506 is provided above the mounting plate 501, a limit adjusting screw 508 is provided above the screw connecting plate 506, and a guide rod 503 is provided on the side of the limit adjusting screw 508 away from the center of the mounting plate 501.

[0050] A guide rod connecting plate 502 is fixedly connected above the guide rod 503. The middle position of the guide rod 503 is also connected through the cylinder mounting plate 504. A set of ejector cylinders 505 are fixedly connected to the left and right sides below the cylinder mounting plate 504. The ejector cylinder 505 has a lifting lug 507 on the side near the center of the mounting plate 501.

[0051] Specifically, after the previous vulcanization process is completed, the quick-closing cylinders 306 on both sides of the upper seat component drive the middle seat assembly 200 to descend to a set height (this height must ensure that the height of the middle seat pad 210 at the top of the middle seat assembly 200 is lower than the pad mounting seat 305 at the bottom of the upper seat assembly 300). The pad cylinder 302 of the upper seat assembly 300 works and pushes the connecting plate 304. The connecting plate 304 drives the upper seat pad 307 to move outward (so that the circular hole in the middle of the upper seat 301 is exposed). Then, the quick-closing cylinder 306 drives the middle seat assembly 200 to rise to a set height (this height is sufficient to ensure that the upper mold or the middle mold can completely detach from the lower mold, so that the circular hole in the middle of the upper seat 301 is exposed and the middle seat assembly 200 rises, and the middle seat pad 210 at the top of the middle seat assembly 200 can pass into the upper seat 301 without obstruction).

[0052] Secondly, the mold-moving cylinder 403 of the lower assembly 400 pushes the mold-moving slide plate 406 outward from the machine, and the lower mold follows. The mold first moves into the first station, and the two side lugs of the middle mold move into the gap between the lifting lugs 507 on both sides of the mold opening assembly 500. The pneumatic limit seat 405 extends its pin to lock the mold-moving slide plate 406. The ejection cylinder 505 of the mold opening assembly drives the lifting lugs 507 to lift the middle mold upward until it is completely separated from the mold and the product. The pneumatic limit seat 405 retracts to release the lock, and then the mold moves into the second station. At this time, the worker operates the hook of the hoist 102 to hook the lifting lug on the mold core, and uses an air gun to pull the mold core out of the product. The worker pulls the product out of the lower mold and cleans the mold, and then performs the reverse steps. The mold-moving slide plate 406 is suddenly moved forward, and the mold-moving cylinder 403 drives the mold-moving slide plate 406 to move inward back to the machine until it touches the mechanical limit point. The quick mold-closing cylinders 306 on both sides of the upper seat assembly 300 drive the middle seat assembly 200 to descend until the upper mold and the middle mold are in contact. The pad block cylinder 302 of the upper seat assembly 300 works to push the connecting plate 304. The connecting plate 304 drives the upper seat pad block 307 to move inward to the middle of the upper seat 301. The mold-locking cylinder 202 pushes the middle seat pad block 210 installed at the end of the piston rod to move upward until it touches the upper seat pad block 307 (the mold-closing stroke of the equipment is adjusted by several middle seat pad blocks 210 of equal height). Then the pressurization program is started to increase the pressure and vulcanization begins, thus completing one production cycle.

[0053] In production, the equipment is set up with a vertical structure, and the product is perpendicular to the mold mounting surface. The parting surface of the product appears in the radial direction of the product. By designing the parting surface to be located at the contact end between the conductive layer and the insulating layer, the insulating layer is free of parting lines, which can improve the overall structural strength of the product. In addition, the mold is opened at the first station during the product removal process, and the product is removed at the second station with the assistance of a hoist, which simplifies the product removal process.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
