[0002] A pole-mounted circuit breaker is an important device used to protect the safe operation of the power system. It is usually installed on the pole of the transmission line. It can quickly cut off the circuit when the power transmission status is abnormal to prevent dangers such as overload and short circuit and protect the power system. Specifically, the pole-mounted circuit breaker includes a pole, a mechanism box and a terminal FTU (Feeder Terminal Unit, distribution switch monitoring terminal). The detection signal of the pole will be transmitted to the terminal FTU. The terminal FTU determines whether the power transmission status is abnormal based on the detection signal of the pole.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] The present application embodiment provides a pole mold 20, see Figures 1 to 5 , used for forming the pole 10.

[0043] For example, see Figure 4 The pole 10 includes a pole body 11 and an insulating layer 12 , and the insulating layer 12 is wrapped around the outer surface of the pole body 11 .

[0044] Exemplarily, the pole 10 includes a conductive rod, a current sensor and a capacitor assembly.

[0045] The conductive rod is sealed in the pole body 11, and the conductive rod is used to connect with the circuit outside the pole 10. The specific structure thereof can refer to the relevant technology in the art, and will not be described in detail here.

[0046] A current sensor is also sealed in the pole body 11 and is used to measure the current of the conductive rod. As an example, the current sensor may include a coil, and the conductive rod may be inserted into the coil, so that the current sensor can measure the current of the conductive rod.

[0047] Here, "sealed in the pole body 11" means that the above-mentioned components are embedded in the pole body 11 through a special embedding technology, so that they form an inseparable whole with the pole body 11. As an example, in the actual production and preparation process, the above-mentioned components can be assembled in advance, and then a sealing material such as epoxy resin is poured thereon, and the sealing material forms the pole body 11 after solidification, thereby realizing the sealing of the above-mentioned components in the pole body 11. Alternatively, the sealing material can be poured into a mold corresponding to the above-mentioned components to form the pole body 11, and then the mold is removed, the above-mentioned components are loaded into the pole body 11 and a secondary pouring is performed, so that the above-mentioned components are sealed in the pole body 11.

[0048] The capacitor assembly is connected to the conductive rod, and the capacitor assembly can be used as a voltage sensor and / or an energy extraction device. When the capacitor assembly is used as a voltage sensor, it can measure the voltage of the voltage rod, and the measured voltage can provide a basis for the circuit breaker on the pole. When the capacitor assembly is used as an energy extraction device, it can obtain electrical energy from the conductive rod, and the obtained electrical energy can be used by other electrical components of the pole circuit breaker.

[0049] In some embodiments, the pole-mounted circuit breaker includes a mechanism box and a pole 10 described in any embodiment of the present application, and the current sensor and / or capacitor assembly is electrically connected to the mechanism box.

[0050] The electrical signals of the current sensor and / or voltage sensor are transmitted to the terminal FTU. The terminal FTU decides whether to send a circuit-breaking signal to the mechanism box based on the electrical signals. After receiving the circuit-breaking signal from the terminal FTU, the mechanism box performs a circuit-breaking operation. The specific structure of the mechanism box can refer to the relevant technology in the field and will not be repeated here.

[0051] Here, please see Figure 4 The insulating layer 12 is wrapped around the outer surface of the pole body 11, and the pole body 11 is arranged in the insulating layer 12. In this way, the pole body 11 can be protected, and the service life of the pole 10 is further improved.

[0052] The specific structure of the insulating layer 12 is not limited. As an example, the insulating layer 12 can be formed by secondary injection molding of insulating materials such as rubber, silicone, and injection molding materials on the outer surface of the pole body 11.

[0053] Here, the pole body 11 is sealed in the insulating layer 12 , so that the stability of the overall structure of the pole 10 and its insulation performance can be improved.

[0054] The pole mold 20 includes a mold body, a die head 26, and an auxiliary demolding mechanism 30. The mold body includes a fixed mold 21 and a movable mold 22. The fixed mold 21 and the movable mold 22 are arranged to form a pole cavity and a mounting groove that are interconnected. The pole cavity is used to form the pole 10. One end of the die head 26 is inserted into the mounting groove to connect with the pole 10 formed in the pole cavity, and the other end of the die head 26 extends out of the mold body. The auxiliary demolding mechanism 30 includes a first demolding component 31 and a second demolding component 32 that cooperate with each other. The first demolding component 31 is arranged on the movable mold 22, and the second demolding component 32 is arranged on the fixed mold 21. Among them, the auxiliary demolding mechanism 30 includes a first state and a second state. In the first state, the die head 26 and the first demolding component 31 are limited and matched, and the first demolding component 31 can act on the pole 10 formed in the pole cavity through the die head 26 under the action of external force, so that the pole 10 has a movement tendency in the direction away from the fixed mold 21; in the second state, the die head 26 and the second demolding component 32 are limited and matched, and the second demolding component 32 can act on the pole 10 formed in the pole cavity through the die head 26 under the action of external force, so that the pole 10 has a movement tendency in the direction away from the movable mold 22.

[0055] Exemplarily, the pole mold 20 is provided with a glue injection port 24 , which is connected to the pole cavity. During injection molding, the melt is injected into the pole cavity through the glue injection port 24 , so that the pole 10 can be formed.

[0056] In some embodiments, the pole mold 20 may be used to mold the insulation layer 12 .

[0057] For example, see Figures 3 to 5 The pole body 11 is embedded in the pole cavity, one end of the die head 26 is connected to the pole body 11, an insulating layer cavity 23 is formed between the outer surface of the pole body 11 and the cavity wall of the pole cavity, and the mold body is provided with a glue injection port 24, which is connected to the insulating layer cavity 23.

[0058] During the molding of the insulating layer 12, the pole body 11 is set in the pole cavity through the die head 26, and an insulating layer cavity 23 is formed between the outer surface of the pole body 11 and the cavity wall of the pole cavity. During injection molding, the melt is injected into the insulating layer cavity 23 through the injection port 24, and the melt enters the insulating layer cavity 23 and fills the insulating layer cavity 23. After molding and cooling, the insulating layer 12 is demolded by the auxiliary demolding mechanism 30 to obtain the insulating layer 12 wrapped on the outer surface of the pole body 11.

[0059] In other embodiments, the pole mold 20 can be used to form the pole body 11, that is, in the actual production and preparation process, a melt such as epoxy resin is poured into the pole cavity of the pole mold 20, and the pole body 11 is formed after the melt solidifies. The auxiliary demolding mechanism 30 is used to assist in the demolding of the pole body 11.

[0060] Exemplarily, the number of the pole cavities may be one or more.

[0061] The multiple mentioned in the embodiments of the present application refers to a number of two or more.

[0062] For example, see Figures 3 to 5 The height direction of the pole mold 20 is perpendicular to the axial direction of the pole 10 , and the glue injection port 24 is formed at the lower part of the insulating layer cavity 23 .

[0063] The fixed mold 21 and the movable mold 22 are arranged to form a pole cavity and a mounting groove that are interconnected, and one end of the die head 26 is inserted into the mounting groove to connect with the formed pole 10 in the pole cavity. In other words, the pole 10 is connected to the pole mold 20 through the die head 26.

[0064] Here, the specific number of the die heads 26 is not limited, and the die heads 26 may be one or more.

[0065] Here, the pole 10 is connected to the pole mold 20 via a die head 26 , that is, the die head 26 is provided to realize the installation of the pole 10 so that the outer surface of the pole body 11 and the cavity wall of the pole cavity form an insulating layer cavity 23 .

[0066] Here, the auxiliary demoulding mechanism 30 is used to cooperate with the die head 26 to separate the driving die 22 from the fixed die 21 and the movable die 22 .

[0067] In the related art, the movable mold and the fixed mold are usually controlled to separate. At this time, a part of the pole is located in the cavity of the fixed mold, and the pole needs to be manually removed from the fixed mold; however, due to the large weight of the pole and the adhesion between the inner surface of the fixed mold cavity and the outer surface of the pole, a large amount of manpower is required to remove the pole, resulting in the problem of difficulty in demolding.

[0068] The pole mold 20 of the embodiment of the present application is provided with a pole cavity, and one end of the die head 26 is passed through the installation groove for connecting with the formed pole 10 in the pole cavity, so that the pole 10 can be moved by moving the die head 22. The pole mold 20 is provided with an auxiliary demoulding mechanism 30 including a first demoulding component 31 and a second demoulding component 32. In a first state, the first demoulding component 31 can act on the pole 10 formed in the pole cavity through the die head 26 under the action of an external force, so that the pole 10 has a movement tendency in a direction away from the fixed mold 21, so as to achieve the separation between the pole 10 and the fixed mold 21; in a second state, the second demoulding component 32 can act on the pole 10 formed in the pole cavity through the die head 26 under the action of an external force, so that the pole 10 has a movement tendency in a direction away from the movable mold 22, so as to achieve the separation between the pole 10 and the movable mold 22. That is to say, the auxiliary demoulding mechanism 30 drives the pole 10 to separate from the fixed mold 21 and the movable mold 22 by acting on the die head 26, thereby reducing the labor of the operator in the demoulding process, which is conducive to improving the problem of difficulty in demoulding and improving production efficiency.

[0069] In the related art, the axial (height) size of the pole is larger than the radial (lateral) size of the pole. If the melt is injected from the bottom of the pole in the direction of positive placement of the pole (that is, the height direction of the pole is parallel to the height direction of the pole mold), the injection height will be too high, and a lot of pressure will be required to press the melt to the top, which will easily leave bubbles in the cavity during injection molding, which may cause pores inside or on the surface of the product, affecting product quality.

[0070] The pole mold 20 of the embodiment of the present application is shown in FIG. Figure 3 to Figure 4 The axial dimension of the pole 10 is greater than the radial dimension of the pole 10, and the injection port 24 is formed at the lower part of the insulating layer cavity 23. Therefore, by setting the axial direction of the pole 10 to be perpendicular to the height direction of the pole mold 20, it is beneficial to reduce the height required for the melt to flow, and ensure that the melt still has high fluidity when it spreads to the top of the insulating layer cavity 23, thereby improving the formation of bubbles in the insulating layer cavity 23, and further improving the problem of pores formed on the appearance surface of the pole 10, thereby improving product quality and aesthetics.

[0071] In some embodiments, see Figures 1 to 3 The movable mold 22 includes a first fixed plate 222 and a sub-movable mold 221, and the sub-movable mold 221 is arranged on the first fixed plate 222; the fixed mold 21 includes a second fixed plate 219 and a sub-fixed mold, and the sub-fixed mold is arranged on the second fixed plate 219. The sub-movable mold 221 and the sub-fixed mold are arranged to form a pole cavity and a mounting groove.

[0072] Exemplarily, the sub-movable mold 221 is arranged opposite to the sub-fixed mold so that the sub-movable mold 221 and the sub-fixed mold are surrounded by a pole cavity and a mounting groove, and the first fixed plate 222 is arranged on the side of the sub-movable mold 221 away from the fixed mold 21, and the second fixed plate 219 is arranged on the side of the sub-fixed mold away from the movable mold 22.

[0073] Here, the first fixed plate 222 is used to install the sub-movable mold 221, and the second fixed plate 219 is used to install the sub-fixed mold, which is beneficial to improve the overall structural strength of the pole mold 20, and the pole mold 20 can be transported by the first fixed plate 222 and the second fixed plate 219, which is beneficial to reduce the situation of the sub-movable mold 221 and the sub-fixed mold.

[0074] It should be noted that the specific structural form of the auxiliary demoulding mechanism 30 is not limited here.

[0075] In some embodiments, please refer to Figures 1 to 3 The first demoulding assembly 31 includes a first mounting member 311 and a first limiting member. One end of the first mounting member 311 is fixedly connected to the first fixing plate 222, and the other end of the first mounting member 311 extends toward the fixed mold 21. The first mounting member 311 is provided with a first avoidance groove 312 for avoiding the die head 26. The first limiting member is detachably disposed on the first mounting member 311 for selectively limiting the die head 26.

[0076] Exemplarily, the first mounting member 311 is a plate-shaped structure.

[0077] One end of the first mounting member 311 is fixedly connected to the first fixing plate 222 , and the other end of the first mounting member 311 extends toward the fixed die 21 for cooperating with the die head 26 .

[0078] Here, the first avoidance groove 312 may penetrate the first mounting member 311 along the thickness direction of the first mounting member 311 , or a partial area of ​​the first mounting member 311 may be thinned to form the first avoidance groove 312 .

[0079] Exemplarily, the first limiting member is detachably provided on the first mounting member 311 , which is convenient for assembly and can reduce the number of the first limiting members, thereby facilitating cost reduction.

[0080] Exemplarily, the first limiting member may be a pin, a screw, a bolt, or the like.

[0081] It should be noted that the specific structural form of the second demoulding component 32 is not limited here.

[0082] In some embodiments, please refer to Figures 1 to 3The second demolding assembly 32 includes a second mounting member 321 and a second limiting member. One end of the second mounting member 321 is fixedly connected to the sub-fixed film, and the other end of the second mounting member 321 extends toward the movable mold 22. The second mounting member 321 is provided with a second avoidance groove 322 for avoiding the die head 26. The second limiting member is detachably arranged on the second mounting member 321 for selectively limiting the die head 26.

[0083] Exemplarily, the second mounting member 321 is a plate-shaped structure.

[0084] One end of the second mounting member 321 is fixedly connected to the sub-fixed film, and the other end of the second mounting member 321 extends toward the movable mold 22 for cooperation with the die head 26 .

[0085] Here, the second avoidance groove 322 may penetrate the second mounting member 321 along the thickness direction of the second mounting member 321 , or a partial area of ​​the second mounting member 321 may be thinned to form the second avoidance groove 322 .

[0086] Exemplarily, the second limiting member is detachably provided on the second mounting member 321, which is convenient for assembly and can reduce the number of the second limiting members, thereby facilitating cost reduction.

[0088] In some embodiments, please refer to Figures 1 to 3 The first avoidance groove 312 and the second avoidance groove 322 enclose a penetration groove 25 adapted to the die head 26 . In the mold closing direction, the die head 26 has a movable margin of a preset distance in the penetration groove 25 .

[0089] Exemplarily, the first avoidance groove 312 is open toward the side away from the first fixed plate 222, and the second avoidance groove 322 is open toward the side away from the second fixed plate 219. In this way, when assembling the pole mold 20, the first avoidance groove 312 can be used to avoid interference between the first mounting member 311 and the die head 26, and the second avoidance groove 322 can be used to avoid interference between the second mounting member 321 and the die head 26.

[0090] In this embodiment, in the mold closing direction, the mold head 26 is provided with a preset distance of movable margin in the penetration groove 25, so that the auxiliary demoulding mechanism 30 can drive the mold head 22 to move a preset distance, thereby assisting the demoulding of the pole 10.

[0091] Exemplarily, the first mounting member 311 and the second mounting member 321 are sequentially arranged along the axial direction of the die head 26 , and the first mounting member 311 is located outside the second mounting member 321 .

[0092] Of course, in other embodiments, the second mounting member 321 may be located outside the first mounting member 311 .

[0093] In some embodiments, please refer to Figures 1 to 3 A first limiting hole 313 is formed at the extending end of the first mounting member 311 , and the extending direction of the first limiting hole 313 is perpendicular to the mold closing direction. The first limiting member is passed through the first limiting hole 313 , and the first limiting member is located on the side of the die head 26 away from the movable mold 22 .

[0094] Here, the first limiting hole 313 may be provided on the groove wall of the first avoidance groove 312 on one side along the extending direction of the first limiting hole 313 , so as to reduce the influence of the first limiting hole 313 on the structural strength of the first mounting member 311 .

[0095] It is also possible that the first limiting holes 313 are provided on the groove walls on both sides of the first avoidance groove 312 along the extension direction of the first limiting hole 313, and the first limiting member can be simultaneously penetrated through the first limiting holes 313 on both sides of the first avoidance groove 312 along the extension direction of the first limiting hole 313. This is beneficial to improving the connection reliability between the first limiting member and the first mounting member 311.

[0096] Exemplarily, the first limiting member passes through the first limiting hole 313 , extends into the first avoiding groove 312 , and abuts against the die head 26 , thereby limiting the die head 26 .

[0097] Here, by setting the first limiting hole 313 on the first mounting member 311, and by the first limiting member passing through the first limiting hole 313, the first limiting member abuts against the die head 26, thereby limiting the die head 26. This structure is simple, easy to operate, and is conducive to improving demoulding efficiency.

[0098] In some embodiments, please refer to Figures 1 to 3 A second limiting hole 323 is provided at the extending end of the second mounting member 321, and the extending direction of the second limiting hole 323 is perpendicular to the mold closing direction. The second limiting member is passed through the second limiting hole 323, and the second limiting member is located on the side of the die head 26 away from the fixed mold 21. In the mold closing state, there is a preset distance between the first limiting member and the second limiting member.

[0099] Here, the second limiting hole 323 may be provided on the groove wall of the second avoidance groove 322 on one side along the extension direction of the second limiting hole 323 , which is helpful to reduce the influence of the second limiting hole 323 on the structural strength of the second mounting member 321 .

[0100] It is also possible that the groove walls on both sides of the second avoidance groove 322 along the extension direction of the second limiting hole 323 are provided with second limiting holes 323, and the second limiting member can be simultaneously penetrated through the second limiting holes 323 on both sides of the second avoidance groove 322 along the extension direction of the second limiting hole 323. This is beneficial to improving the connection reliability between the second limiting member and the second mounting member 321.

[0101] Exemplarily, the second limiting member passes through the second limiting hole 323 , extends into the second avoiding groove 322 , and abuts against the die head 26 , thereby limiting the die head 26 .

[0102] Here, by setting a second limiting hole 323 on the second mounting member 321, and by the second limiting member being inserted into the second limiting hole 323, the die head 26 is abutted against each other, thereby limiting the die head 26. This structure is simple, easy to operate, and is conducive to improving demolding efficiency.

[0103] In the mold closing state, there is a preset distance between the first stopper and the second stopper. Exemplarily, in the first state, the first stopper abuts against the die head 26, and there is a preset distance of movable margin between the second stopper and the die head 26, and in the second state, the second stopper abuts against the die head 26, and there is a preset distance of movable margin between the first stopper and the die head 26.

[0104] In some embodiments, see Figure 2 , the number of the first limiting holes 313 is multiple, and the multiple first limiting holes 313 include a first sub-hole 3131 and a second sub-hole 3132. Along the mold closing direction, the first sub-hole 3131 is arranged between the second sub-hole 3132 and the die head 26. In the first state, the first limiting member is arranged through the first sub-hole 3131 and is limitedly matched with the die head 26, and a preset distance is provided between the first limiting member and the second limiting member. In the second state, the second limiting member is limitedly matched with the die head 26, the first limiting member is arranged through the second sub-hole 3132, and a preset distance is provided between the first limiting member and the second limiting member.

[0105] Here, the first limiting member can be firstly inserted into the first sub-hole 3131, so that the first limiting member is located on the side of the die head 26 away from the movable die 22, and the second limiting member is inserted into the second limiting hole 323, and there is a preset distance between the first limiting member and the second limiting member. The movable die 22 moves in the direction away from the fixed die 21 along the mold opening direction, and the first limiting member drives the die head 22 to move in the direction away from the fixed die 21, so as to drive the pole 10 to move in the direction away from the fixed die 21, so as to realize that the pole 10 is out of the fixed die 21. When it reaches the position of the second limit piece, the first limit piece is inserted into the second sub-hole 3132. At this time, there is also a preset distance between the first limit piece and the second limit piece. The fixed mold 21 drives the mold 22 head to move away from the movable mold 22 through the second limit piece, so as to drive the pole 10 to move away from the movable mold 22, thereby realizing the pole 10 being released from the fixed mold 21. When it moves to the position of the first limit piece, the pole 10 can be separated from the fixed mold 21 and the movable mold 22, and the pole 10 can be prevented from falling directly from the mold body.

[0106] In some embodiments, see Figures 1 to 3 There are multiple auxiliary demoulding mechanisms 30, and each auxiliary demoulding mechanism 30 is arranged at intervals along the circumference of the mold body.

[0107] Exemplarily, the auxiliary demoulding mechanism 30 may be disposed on the top of the pole cavity, or on the side of the pole cavity.

[0108] Of course, auxiliary demoulding mechanisms 30 may also be provided on the top and sides of the pole cavity.

[0109] In this embodiment, by setting the number of auxiliary demoulding mechanisms 30 to be multiple, the pole 10 can be demoulded by multiple auxiliary demoulding mechanisms 30, and the pole 10 can be demoulded from different directions by multiple auxiliary demoulding mechanisms 30, which is beneficial to reducing the difficulty of demoulding the pole 10.

[0110] In some embodiments, see Figures 3 to 5 The pole 10 includes a plurality of sheds 121 convexly arranged. The cavity wall of the pole cavity includes a plurality of shed cavities 231 concavely arranged, and the shed cavities 231 are used to form the sheds 121 .

[0111] Exemplarily, the outer surface of the insulating layer 12 is protrudingly provided with a plurality of sheds 121. The cavity wall of the insulating layer cavity 23 is recessed to form a plurality of shed cavities 231, and at least a portion of the shed cavities 231 are provided with a glue injection port 24 on the cavity wall.

[0112] Here, a plurality of sheds 121 are protrudingly provided on the outer surface of the insulating layer 12 , and the sheds 121 are used to increase the creepage distance of the pole 10 , thereby improving the safety of the operator.

[0113] As an example, a plurality of sheds 121 are arranged at intervals along the axial direction of the pole 10 .

[0114] Here, at least part of the wall of the umbrella skirt cavity 231 is provided with the glue injection port 24 means that the wall of part of the umbrella skirt cavity 231 is provided with the glue injection port 24, or the wall of all the umbrella skirt cavity 231 is provided with the glue injection port 24.

[0115] In this embodiment, by providing the cavity wall of at least part of the shed cavity 231 with a glue injection port 24, on the one hand, it is beneficial for the melt to fill the shed cavity 231 and reduce the generation of bubbles in the shed cavity 231. On the other hand, the molding part of the glue injection port 24 formed on the pole 10 after demolding can be located on the shed 121, which is convenient for polishing and is beneficial for improving the quality and aesthetics of the pole 10.

[0116] In some embodiments, see Figure 3 The number of the sub-movable molds 221 and the sub-fixed molds are both multiple, and the multiple sub-movable molds 221 are sequentially fitted along the axial direction of the pole 10 formed in the pole cavity, and the splicing position of any two adjacent sub-movable molds 221 is located at the umbrella skirt cavity 231. The multiple sub-fixed molds are sequentially fitted along the axial direction of the pole 10 formed in the pole cavity, and the splicing position of any two adjacent sub-fixed molds is located at the umbrella skirt cavity 231.

[0117] There are multiple sub-movable molds 221 and sub-fixed molds, that is, when processing the mold, a single sub-movable mold 221 and a sub-fixed mold can be processed separately, and then the multiple sub-movable molds 221 are sequentially fitted along the axial direction of the pole 10 formed in the pole cavity, and the multiple sub-fixed molds are sequentially fitted along the axial direction of the pole 10 formed in the pole cavity.

[0118] It is understandable that if the entire movable mold 22 or the entire fixed mold 21 is directly processed, not only is the processing difficult, but also if an error occurs during the processing, the entire movable mold 22 or the entire fixed mold 21 can only be scrapped. However, if the sub-movable mold 221 and the sub-fixed mold are processed first, and then the sub-movable mold 221 is spliced ​​into the movable mold 22 and the fixed mold 21, it is not only conducive to reducing the processing difficulty, but also even if an error occurs during the processing of a sub-movable mold 221 or a sub-fixed mold, only the sub-movable mold 221 or a sub-fixed mold needs to be scrapped, which is conducive to reducing costs.

[0119] In this embodiment, the splicing position of any two adjacent sub-movable molds 221 is located at the umbrella skirt cavity 231, and the splicing position of any two adjacent sub-fixed molds is also located at the umbrella skirt cavity 231. During the injection of melt into the insulating layer cavity 23, the splicing position of adjacent sub-movable molds 221 or sub-fixed molds may penetrate into the melt. After the melt is solidified and demolded, the splicing position of the sub-movable molds 221 or the sub-fixed molds may produce a splicing line. By setting the splicing position of adjacent sub-movable molds 221 at the umbrella skirt cavity 231, the splicing line after demolding is located at the outermost side of the umbrella skirt 121, so as to facilitate the removal of the splicing line, which is beneficial to improving the quality and aesthetics of the pole 10.

[0120] It should be noted that the specific splitting method of the movable mold 22 and the specific splitting method of the fixed mold 21 are not limited here.

[0121] Take fixed mold 21 as an example for introduction. Figure 3 The fixed mold 21 includes a first sub-fixed mold 211, a second sub-fixed mold 212, a third sub-fixed mold 213, a fourth sub-fixed mold 214, a fifth sub-fixed mold 215, a sixth sub-fixed mold 216, a seventh sub-fixed mold 217, and an eighth sub-fixed mold 218 which are sequentially spliced ​​along the axial direction of the pole 10.

[0122] Among them, the joint of the first sub-fixed mold 211 and the second sub-fixed mold 212 has an umbrella skirt cavity 231, the joint of the second sub-fixed mold 212 and the third sub-fixed mold 213 has an umbrella skirt cavity 231, the joint of the third sub-fixed mold 213 and the fourth sub-fixed mold 214 has an umbrella skirt cavity 231, the joint of the fourth sub-fixed mold 214 and the fifth sub-fixed mold 215 has an umbrella skirt cavity 231, the joint of the fifth sub-fixed mold 215 and the sixth sub-fixed mold 216 has an umbrella skirt cavity 231, the joint of the sixth sub-fixed mold 216 and the seventh sub-fixed mold 217 has an umbrella skirt cavity 231, and the joint of the seventh sub-fixed mold 217 and the eighth sub-fixed mold 218 has an umbrella skirt cavity 231.

[0123] Exemplarily, the fixed mold 21 and the movable mold 22 are arranged to form two pole cavities, and the fixed mold 21 can include a first sub-fixed mold 211, a second sub-fixed mold 212, a third sub-fixed mold 213, a fourth sub-fixed mold 214, a fifth sub-fixed mold 215, a sixth sub-fixed mold 216, a seventh sub-fixed mold 217, an eighth sub-fixed mold 218, an eighth sub-fixed mold 218, a seventh sub-fixed mold 217, a sixth sub-fixed mold 216, a fifth sub-fixed mold 215, a fourth sub-fixed mold 214, a third sub-fixed mold 213, a second sub-fixed mold 212, and a first sub-fixed mold 211, which are sequentially spliced ​​along the axial direction of the pole 10.

[0124] Exemplarily, the fixed mold 21 and the movable mold 22 are arranged to form two pole cavities, and the fixed mold 21 may include a first sub-fixed mold 211, a second sub-fixed mold 212, a third sub-fixed mold 213, a fourth sub-fixed mold 214, a fifth sub-fixed mold 215, a sixth sub-fixed mold 216, a seventh sub-fixed mold 217, an eighth sub-fixed mold 218, a seventh sub-fixed mold 217, a sixth sub-fixed mold 216, a fifth sub-fixed mold 215, a fourth sub-fixed mold 214, a third sub-fixed mold 213, a second sub-fixed mold 212, and a first sub-fixed mold 211, which are sequentially spliced ​​along the axial direction of the pole 10. In other words, the eighth sub-fixed mold 218 may constitute a part of the two pole cavities at the same time.

[0125] It should be noted that the specific splitting method of the movable mold 22 can refer to the splitting method of the fixed mold 21, which will not be repeated here.

[0126] In some embodiments, see Figures 3 to 5 One end of the pole body 11 is provided with an accommodating cavity 13 , and the pole mold 20 further includes a mold core 28 , which is disposed in the accommodating cavity 13 , and one end of the die head 26 is connected to the pole body 11 through the mold core 28 .

[0127] Exemplarily, the accommodating cavity 13 may be used to install an insulating cylinder and an insulating pull rod of the pole 10 .

[0128] In the related art, taking the melt for molding the insulating layer 12 as a silicone melt as an example, the fluidity of the silicone melt is low, and the space of the insulating layer cavity 23 is relatively narrow. Therefore, it is necessary to apply a certain pressure to the insulating layer cavity 23 to fill the silicone melt into the insulating layer cavity 23 to form an insulating layer 12 covering the surface of the pole body 11.

[0129] In this embodiment, a core mold 28 is provided in the accommodating cavity 13 to support the pole 10, which is beneficial to improve the situation that the accommodating cavity 13 is flattened during injection molding, or improve the surface damage of the pole body 11. After the insulating layer 12 is solidified and demoulded, the core mold is taken out.

[0130] In addition, by connecting the mold core 28 to the die head 26 , it is convenient to remove the mold core 28 through the die head 26 , and it is also convenient to install the die head 26 .

[0131] In some embodiments, see Figure 3 to Figure 4 The fixed mold 21 and the movable mold 22 are provided with grooves 27 extending along the edge of the pole cavity.

[0132] After the injection molding is completed, the groove 27 will be filled with melt to form a melt strip. There is a melt sheet between the melt strip and the insulating layer 12 due to the mold gap of the mold body. After demolding, the melt sheet can be torn off at the same time as the melt strip, which is convenient for removing the melt sheet, which is beneficial to improving production efficiency and improving the aesthetics of the pole 10.

[0133] In some embodiments, see Figure 3 to Figure 4 The pole mold 20 has a symmetry plane parallel to the mold closing direction, and the fixed mold 21 and the movable mold 22 are arranged to form two pole cavities, and the two pole cavities are symmetrically arranged about the symmetry plane.

[0134] Here, by setting the number of the pole cavities to two, the pole mold 20 can form two poles 10 in one injection molding process, which improves production efficiency and is also beneficial to the molding of the pole mold 20.

[0135] In this embodiment, the two pole cavities are arranged symmetrically about the symmetry plane, which is beneficial to the layout of the pole mold 20 and thus helps to improve the structural compactness of the pole mold 20 .

[0136] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
