Description

Technical Field

[0001] The present invention relates to the technical field of insulator casting and molding devices, and specifically to a GIS insulator uniform casting device. Background Technique

[0002] Resin insulation components in GIS equipment, including insulating tie rods, post insulators, and pot insulators, must have high insulation performance to ensure the safety and reliability of the equipment. During the manufacturing process of insulators, it is necessary to ensure that there are no bubbles and cracks inside, otherwise it will affect their insulation performance and mechanical strength. To ensure the quality and performance of insulators, the casting process must be uniform to avoid local material shortage or overcasting.

[0003] In the prior art, a new type of columnar porcelain insulator forming tooling with the publication number of CN209312509U has the effect of vibrating the casting mold to discharge the air bubbles in the filler and glue in the casting mold, improving the production quality of porcelain insulators; through the control of the turntable by the motor, the function of reciprocatingly pushing the push column in the support frame is realized, so that the first clamping block reciprocatingly moves in the second compression spring and the third compression spring through the sliding block, thereby generating slight vibration on the casting mold to discharge the gas, solving the problem that the presence of air bubbles between the glue during the casting process of adding filler and glue will reduce the surface quality of the formed porcelain insulator.

[0004] However, in the actual use process, even if the casting cylinder and the mold are vacuum-treated before casting to remove the air in them, once the epoxy resin casting speed is too fast, it may cause the air to be involved in the casting cylinder again, forming air bubbles and affecting the casting and molding effect of GIS insulators.

[0005] Therefore, the present invention proposes a GIS insulator uniform casting device to solve the problems of possible local material shortage or overcasting in the traditional casting method, resulting in uneven mold cavity filling and inconsistent quality. The method of casting sequentially from the center to the periphery can be adopted to make the distribution of the epoxy resin casting material in the mold more uniform, and at the same time, it has certain advantages in reducing air bubbles, making the casting more uniform, and enhancing the casting strength of the insulator.

Detailed implementation manners

[0039] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] Example 1. Please refer to Figures 1-19 , the present invention provides a technical solution: a uniform pouring device for GlS insulators, including a base 1. A lower mold base 11 is fixedly installed at the upper end of the base 1. A lower mold cavity 110 is arranged inside the lower mold base 11. An upper mold base 12 is movably connected to the upper end of the lower mold base 11. An upper mold cavity 121 is arranged on the inner surface of the upper mold base 12. A central runner circular seat 122 is arranged in the central inner cavity of the upper mold cavity 121. A protective frame 2 is fixedly installed at the upper end of the central runner circular seat 122. A central injection pipe 3 is connected through the central inner wall of the protective frame 2. A limiting circular groove 30 is opened at the bottom of the inner cavity of the central injection pipe 3. A runner mechanism is arranged between the upper mold cavity 121 and the central runner circular seat 122. The runner mechanism includes a parallel runner assembly and a stepped storage runner assembly. The stepped storage runner assembly is arranged in the cavity formed by the central runner circular seat 122 and the upper mold cavity 121. A floating plugging mechanism is arranged inside the central injection pipe 3. The floating plugging mechanism includes a floating rod 35. The outer surface of the floating rod 35 is slidably connected to the inner wall of the limiting circular groove 30. The two ends of the floating rod 35 are respectively connected with a successive plugging member and a floating member. An auxiliary shock member is arranged on the upper side surface of the central injection pipe 3. Guide members are arranged on both sides of the auxiliary shock member. One end of the guide member is connected to the floating member; An activity groove 1210 is opened on the bottom surface of the inner cavity of the upper mold cavity 121. The inner surface of the activity groove 1210 is fixedly connected to the outer surface of the lower end of the central injection pipe 3. A receiving groove 12101 is opened through the lower end of the activity groove 1210. The activity groove 1210 and the receiving groove 12101 are coaxially distributed about the center of the upper mold cavity 121;

[0041] In this embodiment, through the cooperation of the runner mechanism and the floating plugging mechanism, the automatic pouring of the mold cavity is realized. By changing the runner and gate design and adopting the method of successive pouring from the center to the periphery, the distribution of the epoxy resin pouring material in the mold is made more uniform, the formation of air bubbles in the mold cavity is reduced, and the pouring material gradually diffuses to the edge of the mold, avoiding the situation of local material shortage or over-pouring that may occur in the traditional pouring method; And through the interaction of the guide member and the auxiliary shock member, not only the stable limit of the floating member is satisfied, but also the intermittent knocking of the central injection pipe 3 is satisfied, reducing the wall hanging phenomenon while enhancing the pouring density and improving the strength of the insulator pouring and forming.

[0042] Example 2. Refer to the appendix Figures 1-19, on the basis of the first embodiment, in order to achieve uniform pouring of the pouring cavity, this embodiment proposes that the parallel flow channel assembly includes a first shunt pipe 31, a second shunt pipe 32, and a third shunt pipe 33. The input ends of the first shunt pipe 31, the second shunt pipe 32, and the third shunt pipe 33 are respectively and communicatively connected to the inner wall of the central injection pipe 3. The first shunt pipe 31, the second shunt pipe 32, and the third shunt pipe 33 are parallelly distributed from the inside to the outside. The stepped flow storage assembly includes a first annular injection flat pipe 311, a second annular injection flat pipe 321, and a third annular injection flat pipe 331. The output end of the first shunt pipe 31 is communicatively connected to the upper inner wall of the first annular injection flat pipe 311. The output end of the second shunt pipe 32 is communicatively connected to the upper inner wall of the second annular injection flat pipe 321. The output end of the third shunt pipe 33 is communicatively connected to the upper inner wall of the third annular injection flat pipe 331. The centers of the first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331 are coaxially distributed, and the first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331 form a stepped structure that decreases from the inside to the outside. The first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331 are all hollow annular structures. The lower inner walls of the first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331 are uniformly connected with array discharge pipes 34;

[0043] In this embodiment, as Figures 11-16 shown, three flow channel layers of different heights are provided on the central injection pipe 3, namely the first shunt pipe 31, the second shunt pipe 32, and the third shunt pipe 33. These three flow channels respectively penetrate the inner wall of the central flow channel round seat 122, and the output ends are respectively connected to the first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331. Here, the first annular injection flat pipe 311, the second annular injection flat pipe 321, and the third annular injection flat pipe 331 are hollow annular cavities for injecting epoxy resin materials. It should be noted that these three annular structures are arranged in sequence from the inside to the outside. The height of the first annular injection flat pipe 311 is higher than that of the second annular injection flat pipe 321, and the second annular injection flat pipe 321 is higher than the third annular injection flat pipe 331, forming an obvious stepped layout.

[0044] Embodiment 3, referring to the attached Figures 1-19, on the basis of the second embodiment, in order to realize the automatic sealing of the pouring outlets at different heights of the central pouring pipe 3, this embodiment further proposes that: the sequential sealing member includes a conical sealing block 351, the upper part of the conical sealing block 351 is in a frustum structure, and diversion inclined grooves 3510 are uniformly formed on the upper inclined surface of the conical sealing block 351; an annular groove 35100 is formed on the inner wall of the outer ring in the middle section of the conical sealing block 351, and sealing members are sleeved and installed at both ends of the annular groove 35100. The sealing members include flexible sealing ring plates 35101, and ball installation grooves 35102 are uniformly formed on the outer wall surface of the annular groove 35100, and rolling balls 35103 are rotatably installed inside the ball installation grooves 35102;

[0045] In this embodiment, after the lower mold base 11 and the upper mold base 12 are completely closed, an external transfer pump is connected to the central pouring pipe 3 to pour the epoxy resin material. At this time, the three-level shunt pipes are respectively distributed on the central pouring pipe 3. At this time, the top of the conical sealing block 351 forms a seal for the lower end of the central pouring pipe 3. When the epoxy resin injection material falls under the action of gravity, the injection material will first be output through the input end of the first shunt pipe 31. The injection material enters the first annular injection flat pipe 311, and then is injected into the mold cavity through the uniformly arranged array discharge pipes 34, as Figure 13 shown, at this time the input port of the first shunt pipe 31 is open; when the injection material is poured into the mold cavity to a certain extent, the floating flat plate 352 is lifted by the poured epoxy resin material. At this time, the floating flat plate 352 touches the floating rod 35 and rises, so that the conical sealing block 351 is lifted synchronously, as Figure 14 shown, at this time the conical sealing block 351 completely seals the input end of the first shunt pipe 31, and the injection material is discharged through the input ports of the second shunt pipe 32 and the third shunt pipe 33. At this time, the injection material will also first fill the second annular injection flat pipe 321 and be discharged. When the injection material discharged from the array discharge pipes 34 at the lower end of the second annular injection flat pipe 321 covers the material poured first in the center, the floating flat plate 352 rises to a certain extent again under the influence of the injection material, so as to seal the input port of the second shunt pipe 32. Finally, when the mold cavity is completely poured, the input port of the third shunt pipe 33 is sealed. At this time, after the central pouring pipe 3 is sealed by the conical sealing block 351, the feeding is stopped and the transfer pump is turned off;

[0046] It should be noted that a diversion chute 3510 adapted to the positions of the respective shunt pipes is provided on the top side inclined surface of the conical plugging block 351, which can accelerate the flow of the injection material. And through the opening of the annular groove 35100, the flexible sealing ring plate 35101 and the ball mounting groove 35102 are accommodated. When the conical plugging block 351 moves up and down, the flexible sealing ring plate 35101 is in close contact with the inner wall of the central injection pipe 3, so that the surplus material on the side wall of the central injection pipe 3 can be scraped off, preventing it from entering between the two flexible sealing ring plates 35101 and affecting the normal rolling of the ball mounting groove 35102. The ball mounting groove 35102 here can assist the conical plugging block 351 to make a smoother floating and plugging action; it is worth noting that the flexible sealing ring plate 35101 here not only plays a sealing role, but also realizes the protection of the ball mounting groove 35102, serving multiple purposes with one object.

[0047] Example 4. Refer to the appendix Figures 1-19 , on the basis of Example 3, in order to achieve the stable floating of the conical plugging block 351 and the floating rod 35, this example proposes a floating flat plate 352: The floating member includes a floating flat plate 352. The upper center of the floating flat plate 352 is fixedly connected to the lower end of the floating rod 35. A central collar 3521 is fixedly sleeved on the outer surface of the lower end of the floating rod 35. An arc-shaped support piece 3523 is fixedly connected to the outer surface of the central collar 3521. There are eight groups of arc-shaped support pieces 3523, which are arranged in a circular array centered on the floating rod 35. The other ends of the eight groups of arc-shaped support pieces 3523 are fixedly connected to an outer ring plate 3522. The inner ring surface of the outer ring plate 3522 is movably embedded with the outer surface of the floating flat plate 352;

[0048] In this example, as Figure 17 shown, the lower end of the floating rod 35 is connected to the floating flat plate 352. Both sides of the floating flat plate 352 are flat surfaces. The bottom side of the floating flat plate 352 is in contact with the epoxy resin injection material. Through the mutual cooperation of the central collar 3521, the outer ring plate 3522 and the arc-shaped support pieces 3523, while supporting the floating flat plate 352, the arrayed arc-shaped support pieces 3523 ensure the balanced force of the floating flat plate 352. When the mold cavity injection material is completely filled, the floating flat plate 352 enters the receiving groove 12101 for embedding. At this time, the bottom surface of the floating flat plate 352 forms a closure for the receiving groove 12101, so as to form a flat surface at the bottom of the upper mold cavity 121.

[0049] Example 5. Refer to the appendix Figures 1-19, on the basis of the fourth embodiment, in order to achieve the balanced floating and limit guiding of the floating flat plate 352, this embodiment proposes that: the guiding member includes a lifting rack 36 and a central rod 362. The two ends of the central rod 362 are respectively rotatably connected to the inner wall of the protective frame 2. The lower end of the lifting rack 36 is fixedly connected to the surface of the floating flat plate 352. Limiting chutes are respectively opened on both sides of the receiving groove 12101, and the inner surface of the limiting chute is slidably connected to one side surface of the lifting rack 36. A transmission gear 361 is meshed and rotated on the outer surface of the upper side of the lifting rack 36, and the central inner surface of the transmission gear 361 is fixedly connected to the outer surface of the central rod 362; Connecting cams 363 are respectively arranged on both sides of the transmission gear 361, and the inner surface of the connecting cam 363 is fixedly connected to the outer surface of the central rod 362. Display turntables 364 are respectively movably connected to the two ends of the central rod 362, and the display turntables 364 are fixedly installed on the outside of the protective frame 2; A pointer is arranged on the outer surface of one end of the central rod 362 close to the display turntable 364, and the pointer is rotatably installed on the display turntable 364; The auxiliary shock member includes a connecting collar 37 and a connecting steel sheet 371. The connecting collar 37 is in an annular sheet structure, the inner surface of the connecting collar 37 is fixedly connected to the outer surface of the central injection pipe 3, the connecting steel sheet 371 is fixedly installed on the outer surfaces of both sides of the connecting collar 37, and the distribution positions of the connecting collar 37 and the connecting cam 363 are adapted;

[0050] In this embodiment, as Figure 9 and Figures 11-12As shown, during the process of the floating plate 352 floating upward, the lifting gear rod 36 connected to the floating plate 352 moves upward synchronously, and the outer teeth of the lifting gear rod 36 match the outer surface of the transmission gear 361. At this time, the transmission gear 361 drives the center rod 362 to rotate, and at this time, the pointer at one end of the center rod 362 moves on the display dial 364. In this way, the floating height of the floating plate 352 can be judged by the rotation angle formed by the pointer and the display dial 364, and the blocking position of the conical blocking block 351 can be judged in this way; it should be noted that by connecting the connecting cam 363 to the center rod 362, when the center rod 362 rotates, the connecting cam 363 rotates synchronously. Due to the cam design, the connecting cam 363 intermittently applies a toggling action to the connecting steel sheet 371 on one side, causing The shaking of the connecting steel sheet 371 is transmitted to the connecting ring 37 and the center injection tube 3, thereby realizing the auxiliary shock function of the center injection tube 3. Through such a design, while ensuring the overall floating guidance of the floating plate 352, it also satisfies the auxiliary shock of the center injection tube 3, avoids hanging material, and can also ensure the injection filling density, avoid or reduce the formation of bubbles; and it should be noted that before the pouring operation of the floating plate 352 is carried out, the bottom of the conical blocking block 351 is on the bottom surface of the inner cavity of the center injection tube 3. When the mold cavity is completely filled, the floating plate 352 floats to the position of the receiving groove 12101. When the next pouring is required, the floating plate 352 can be reset to the initial position by manually turning the pointer and reversing the center rod 362.

[0051] Embodiment 6, refer to the attached Figures 1-19 On the basis of the fifth embodiment, the present invention further proposes a method for using a GLS insulator uniform casting device, comprising the following steps:

[0052] Step 1: connect the input end of the central injection pipe 3 to the external feeding equipment and the delivery pump, and after the lower mold base 11 and the upper mold base 12 are completely molded, start the delivery pump to pour the epoxy resin material;

[0053] Step 2: At this time, the three levels of shunt pipes are respectively distributed on the central injection pipe 3. At this time, the top of the conical blocking block 351 forms a blockage on the lower end of the central injection pipe 3. When the epoxy resin injection material is discharged by gravity, the injection material will first be output through the input end of the shunt pipe 1 31, and the injection material will enter the annular injection flat pipe 1 311, and then be injected into the mold cavity through the evenly arranged array discharge pipes 34. At this time, the input port of the shunt pipe 1 31 is open;

[0054] Step 3: When the injection material is poured into the mold cavity to a certain extent, the floating plate 352 is lifted by the poured epoxy resin material. The floating plate 352 touches the floating rod 35 and rises, causing the conical blocking block 351 to be lifted synchronously. The conical blocking block 351 completely blocks the input end of the first shunt pipe 31, and the injection material is discharged through the input ports of the second shunt pipe 32 and the third shunt pipe 33. At this time, the injection material will first fill the second annular injection flat pipe 321 and then be discharged;

[0055] Step 4: When the injection material discharged from the array of discharge pipes 34 at the lower end of the second annular injection flat pipe 321 covers the material poured in the center first, the floating plate 352 rises to a certain extent again under the influence of the injection material, thus blocking the input port of the second shunt pipe 32. Finally, when the mold cavity is completely filled, the input port of the third shunt pipe 33 is blocked. At this time, after the central injection pipe 3 is blocked by the conical blocking block 351, the feeding is stopped and the transfer pump is turned off;

[0056] Step 5: During the upward floating process of the floating plate 352, the lifting rack 36 connected to the floating plate 352 moves upward synchronously. The outer teeth of the lifting rack 36 are adapted to the outer surface of the transmission gear 361. The transmission gear 361 drives the central rod 362 to rotate. At this time, the pointer at one end of the central rod 362 moves on the display turntable 364. The floating height of the floating plate 352 is judged by the rotation angle formed by the pointer and the display turntable 364, so as to judge the position blocked by the conical blocking block 351. Finally, the poured material is cooled and formed. After separating the upper mold base 12 from the lower mold base 11, the formed GlS insulator is ejected by using the mold ejecting mechanism, which is convenient for the next pouring.
