[0002] Post insulators are a special type of insulating control that plays a vital role in power systems, especially in overhead transmission lines. During the production and processing of post insulators, the silicone rubber raw material needs to be squeezed into the mold by a press, so that the silicone rubber raw material is wrapped around the insulator core rod to form the required insulator shape;

[0003] At present, when placing the insulator core rod into the mold, it is necessary to install limit rods on both ends of the thread. The limit rods ensure that the position of the insulator core rod in the mold is accurate, which can prevent the insulator core rod from moving during injection molding, thereby ensuring the stability and consistency of the finished insulator product. After the injection molding of the insulator is completed, the limit rod needs to be removed from the insulator core rod by thread. The connection and disassembly of the limit rod are all done manually, which increases the workload and also has a certain impact on the production efficiency of the post insulator.

The limiter 4 includes a positioning member 41 that can be inserted into the connecting groove 51 of the insulator core rod 5 to limit it. The limiter 4 further includes a connecting plate 42. A plurality of positioning members 41 are provided on the connecting plate 42. A telescopic device 43 is provided below the connecting plate 42. The telescopic device 43 is provided on the lower mold 3 and the output shaft is connected to the connecting plate 42. By symmetrically arranging the limiters 4, the two ends of the insulator core rod 5 can be resisted, thereby positioning the insulator core rod 5. The positioning member 41 includes a fixing plate 415 and a positioning rod 411. The fixing plate 415 is fixedly connected to the connecting plate 42. An activity hole 416 is provided on the fixing plate 415. The positioning rod 411 is movably located in the activity hole 416. A positioning block 412 and a spring 414 are sleeved on the positioning rod 411. The spring 414 is located between the positioning block 412 and the fixing plate 415. By inserting the positioning rod 411 into the connecting groove 51 on the insulator core rod 5, the position of the insulator core rod 5 can be positioned.

[0030] Further, a plurality of upper templates 21 are provided on the upper mold 2, and upper forming grooves 212 are provided on each of the plurality of upper templates 21. A plurality of grooves 22 are provided on the upper mold 2, and the plurality of grooves 22 respectively correspond to a plurality of positioning members 41 on the lower template 31. Through the grooves 22, the positioning members 41 will not affect the normal closing of the upper mold 2 and the lower mold 3 when they are closed. Limiting grooves one 211 are symmetrically provided on the upper template 21, and the limiting grooves one 211 communicate with the upper forming grooves 212. Limiting grooves two 312 are symmetrically provided on the lower template 31, and the limiting grooves two 312 communicate with the lower forming grooves 311. When the upper mold 2 and the lower mold 3 are closed, the normal closing of the upper mold 2 and the lower mold 3 is ensured through the limiting grooves one 211 and the limiting grooves two 312.

[0031] Furthermore, a plurality of lower templates 31 are provided on the lower mold 3, and lower forming grooves 311 are provided on each of the plurality of lower templates 31. Movable grooves 32 are symmetrically provided on the lower template 31, and the positions of the two movable grooves 32 respectively correspond to the two positioning members 41. Through the movable grooves 32, sufficient space is ensured for the limiting member 4 to retract, and the limiting member 4 can retract into the movable grooves 32 before the upper mold 2 and the lower mold 3 are closed.

[0032] It should be noted that a positioning plate 413 is sleeved on the positioning rod 411, and a corresponding first positioning groove 213 and a second positioning groove 313 are respectively formed on the upper template 21 and the lower template 31. When the upper mold 2 and the lower mold 3 are closed, the position of the positioning plate 413 can be fixed through the first positioning groove 213 and the second positioning groove 313.

[0033] During use, the positioning rod 411 is moved towards the spring 414. The spring 414 can be compressed through the positioning block 412, thereby increasing the distance between the two positioning rods 411 on the two positioning members 41. The insulator mandrel 5 to be injection-molded is placed between the two positioning rods 411 on the two positioning members 41, and the positioning rod 411 is aligned with the connecting groove 51 on the insulator mandrel 5. The resilience of the spring 414 can push the positioning rod 411 into the connecting groove 51 on the insulator mandrel 5. By inserting the two positioning rods 411, the insulator mandrel 5 can be clamped and positioned. After several insulator mandrels 5 are all installed, the telescopic device 43 is activated. The output shaft of the telescopic device 43 drives the connecting plate 42 to move downward, and the connecting plate 42 can be moved into the movable groove 32. Moreover, the insulator mandrels 5 are respectively located in the corresponding lower molding grooves 311, and the positioning rods 411 move into the second limiting grooves 312. One end of the limiting block facing the insulator mandrel 5 is in close contact with the side surface of the lower mold 3. When the upper mold 2 and the lower mold 3 are combined together, when the upper mold 2 moves downward and merges with the lower mold 3, the positioning rod 411 is covered by the first limiting groove 211 and the second limiting groove 312. By clamping and resisting the insulator mandrel 5 with the two positioning rods 411, the insulator mandrel 5 can be limited. Moreover, the positioning plate 413 on the positioning rod 411 is located in the first positioning groove 213 and the second positioning groove 313. By fixing the positioning plate 413 through the first positioning groove 213 and the second positioning groove 313, the position of the positioning rod 411 is fixed. The positioning rod 411 performs stable position limiting on the insulator mandrel 5, which can prevent the insulator mandrel 5 from moving during the injection molding process. After the injection molding of the post insulator is completed and the upper mold 2 and the lower mold 3 are separated, the telescopic device 43 activates its output shaft to push the connecting plate 42 upward, so that the limiting member 4 drives the completed post insulator to move upward, which can assist in peeling the completed injection-molded post insulator from the lower mold 3. Before and after the injection molding of the insulator mandrel 5, there is no need to manually thread-connect the limiting rod, effectively reducing the labor intensity of workers and further improving the processing and forming efficiency of the post insulator.
