Description

Technical Field

[0001] The invention relates to the technical field of insulator casting and molding devices, in particular to a GLS insulator uniform casting device. Background Art

[0002] The resin insulation components in GIS equipment, including insulating rods, post insulators and pot insulators, must have high insulation performance to ensure the safety and reliability of the equipment. During the manufacturing process, the insulators must be free of bubbles and cracks inside, otherwise it will affect its insulation performance and mechanical strength. In order to ensure the quality and performance of the insulators, the casting process must be uniform to avoid local material shortage or excessive casting.

[0003] In the prior art, there is a novel column-type porcelain insulator forming tool with publication number CN209312509U, which has the effect of being able to vibrate the casting mold to discharge the bubbles in the filler and the glue in the casting mold, thereby improving the production quality of the porcelain insulator; through the control of the turntable by the motor, the function of reciprocating the pushing column in the support frame is realized, so that the first clamping block reciprocates in the second compression spring and the third compression spring through the sliding block, thereby generating a slight vibration on the casting mold to discharge the gas, thereby solving the problem that the casting process of adding filler and glue will cause bubbles to exist between the glue, which will cause the surface quality of the formed porcelain insulator to decrease.

[0004] However, in actual use, even if the pouring tube and the mold are vacuum treated before pouring to remove the air, once the epoxy resin is poured too fast, the air may be drawn into the pouring tube again to form bubbles, affecting the casting and molding effect of the GLS insulator.

[0005] Therefore, the present invention proposes a uniform casting device for GIS insulators to solve the problem of local material shortage or excessive casting that may occur in traditional casting methods, resulting in unbalanced filling of the mold cavity and inconsistent quality. The method of successive casting from the center to the periphery can be adopted to make the distribution of the epoxy resin casting material in the mold more uniform. At the same time, it has certain advantages in reducing bubbles, making the casting more uniform and enhancing the casting strength of the insulator. Summary of the invention

[0042] Embodiment 2, refer to the attached Figure 1-19On the basis of the first embodiment, in order to achieve uniform pouring of the pouring cavity, the present embodiment proposes: the parallel flow channel assembly includes a shunt tube 1 31, a shunt tube 2 32 and a shunt tube 3 33, the input ends of the shunt tube 1 31, the shunt tube 2 32 and the shunt tube 3 33 are respectively connected with the inner wall of the central injection tube 3, and the shunt tube 1 31, the shunt tube 2 32 and the shunt tube 3 33 are distributed in parallel from the inside to the outside; the stepped flow storage assembly includes an annular injection flat tube 1 311, an annular injection flat tube 2 321 and an annular injection flat tube 3 331, the output end of the shunt tube 1 31 is connected with the inner wall of the upper end of the annular injection flat tube 1 311, and the output end of the shunt tube 2 32 is connected with the inner wall of the annular injection flat tube 3 The upper inner wall of the second annular injection flat tube 321 is connected through, the output end of the shunt pipe three 33 is connected through the upper inner wall of the annular injection flat tube three 331, the annular injection flat tube one 311, the annular injection flat tube two 321 and the annular injection flat tube three 331 are coaxially distributed, and the annular injection flat tube one 311, the annular injection flat tube two 321 and the annular injection flat tube three 331 form a stepped structure that decreases from the inside to the outside, the annular injection flat tube one 311, the annular injection flat tube two 321 and the annular injection flat tube three 331 are all hollow annular structures, and the array discharge pipes 34 are evenly connected to the inner walls of the lower ends of the annular injection flat tube one 311, the annular injection flat tube two 321 and the annular injection flat tube three 331;

[0043] In this embodiment, if Figure 11-16 As shown, three flow channel layers of different heights are arranged on the central injection pipe 3, namely, the diverter pipe 1 31, the diverter pipe 2 32 and the diverter pipe 3 33. The 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 annular injection flat tube 1 311, the annular injection flat tube 2 321 and the annular injection flat tube 3 331. Here, the annular injection flat tube 1 311, the annular injection flat tube 2 321 and the annular injection flat tube 3 331 are hollow annular cavities for injecting epoxy resin materials. It is worth noting that the three annular structures are arranged in sequence from the inside to the outside, the annular injection flat tube 1 311 is higher than the annular injection flat tube 2 321, and the annular injection flat tube 2 321 is higher than the annular injection flat tube 3 331, forming an obvious stepped layout.

[0044] Embodiment 3, refer to the attached Figure 1-19On the basis of the second embodiment, in order to realize the automatic plugging of the pouring outlets at different heights of the central injection pipe 3, the present embodiment further proposes: the successive plugging parts include a conical plugging block 351, the upper part of the conical plugging block 351 is a frustum structure, and the upper inclined surface of the conical plugging block 351 is evenly provided with guide chute 3510; an annular groove 35100 is provided on the inner wall of the outer ring of the middle section of the conical plugging block 351, and sealing members are sleeved and installed at both ends of the annular groove 35100, and the sealing members include a soft sealing ring plate 35101, and ball mounting grooves 35102 are evenly provided on the outer ring wall of the annular groove 35100, and rolling balls 35103 are rotatably installed on the inner side of the ball mounting groove 35102;

[0045] In this embodiment, after the lower mold base 11 and the upper mold base 12 are completely molded, the epoxy resin material is poured through the central injection pipe 3 connected to an external delivery pump. At this time, the three levels of branch 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 is discharged by gravity, the injection material will first be output through the input end of the branch pipe 1 31, and the injection material will enter the annular injection flat pipe 1 311, and then the material will be injected into the mold cavity through the evenly arranged array discharge pipes 34. Fig.13 As shown, the input port of the shunt pipe 31 is open at this time; when the injection material is poured into the mold cavity to a certain extent, the floating plate 352 is lifted up by the poured epoxy resin material, and the floating plate 352 touches the floating rod 35 and rises, so that the conical blocking block 351 is lifted synchronously, as shown in FIG. Fig.14 As shown, at this time, the conical blocking block 351 completely blocks the input end of the shunt pipe 1 31, and the injected material is discharged through the input ports of the shunt pipe 2 32 and the shunt pipe 3 33. At this time, the injected material will first fill the annular injection flat pipe 2 321 and discharge the material. When the injected material discharged from the array discharge pipe 34 at the lower end of the annular injection flat pipe 2 321 covers the material first poured in the center, the floating plate 352 rises to a certain extent again under the influence of the injected material, thus blocking the input port of the shunt pipe 2 32. Finally, when the mold cavity is completely poured, the input port of the 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 delivery pump is turned off.

[0046] It should be noted that the top side inclined surface of the conical sealing block 351 here is provided with a guide groove 3510 which is adapted to the position of each diversion pipe, which can accelerate the flow of the injection material, and through the opening of the annular groove 35100, the soft sealing ring plate 35101 and the ball mounting groove 35102 are accommodated. When the conical sealing block 351 moves up and down, the soft sealing ring plate 35101 is in close contact with the inner wall of the central injection pipe 3, which can achieve the scraping of the residual material on the side wall of the central injection pipe 3 to avoid entering between the two groups of soft 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 sealing block 351 to make a smoother floating and sealing action. It is worth noting that the soft sealing ring plate 35101 here not only has a sealing effect, but also realizes the protection of the ball mounting groove 35102, which is a multi-purpose object.

[0047] Embodiment 4, refer to the attached Figure 1-19 On the basis of the third embodiment, in order to realize the stable floating of the conical blocking block 351 and the floating rod 35, the present embodiment proposes a floating plate 352: the floating member includes a floating plate 352, the central upper end of the floating plate 352 is fixedly connected to the lower end of the floating rod 35, the outer surface of the lower end of the floating rod 35 is fixedly sleeved with a central collar 3521, the outer surface of the central collar 3521 is fixedly connected with an arc-shaped support piece 3523, the arc-shaped support piece 3523 is provided with eight groups and is arranged in a central circular array with respect to the floating rod 35, the other end of the eight groups of arc-shaped support pieces 3523 is fixedly connected with an outer ring plate 3522, and the inner ring surface of the outer ring plate 3522 is movably engaged with the outer surface of the floating plate 352;

[0048] In this embodiment, if Fig.17 As shown, the lower end of the floating rod 35 is connected to the floating plate 352, and both sides of the floating plate 352 are flat. The bottom side of the floating plate 352 is in contact with the epoxy resin injection material. The floating plate 352 is supported by the cooperation of the center ring 3521, the outer ring plate 3522 and the arc-shaped support piece 3523. At the same time, the array-arranged arc-shaped support pieces 3523 ensure that the floating plate 352 is subjected to balanced force. When the mold cavity is completely filled with injection material, the floating plate 352 enters the receiving groove 12101 for embedding. At this time, the bottom surface of the floating plate 352 is closed to the receiving groove 12101, so that the bottom of the upper mold cavity 121 forms a plane.

[0049] Embodiment 5, refer to the attached Figure 1-19On the basis of the fourth embodiment, in order to realize the balanced floating and limited guiding of the floating plate 352, the present embodiment proposes that: the guide member includes a lifting gear rod 36 and a center rod 362, the two ends of the center rod 362 are respectively connected to the inner wall of the protection frame 2 for rotation, the lower end of the lifting gear rod 36 is fixedly connected to the surface of the floating plate 352, and the two sides of the receiving groove 12101 are respectively provided with limited sliding grooves, the inner surface of the limited sliding groove is slidably connected to the one side surface of the lifting gear rod 36, the upper outer surface of the lifting gear rod 36 is meshed and rotated with a transmission gear 361, and the central inner surface of the transmission gear 361 is fixedly connected to the outer surface of the center rod 362; the two sides of the transmission gear 361 are respectively provided with connecting Cam 363, the inner surface of the connecting cam 363 is fixedly connected to the outer surface of the center rod 362, and the two ends of the center rod 362 are respectively movably connected with display dials 364, and the display dial 364 is fixedly installed on the outer side of the protective frame 2; the outer surface of the center rod 362 close to the display dial 364 is provided with a pointer, and the pointer is rotatably installed on the display dial 364; the auxiliary shock member includes a connecting ring 37 and a connecting steel sheet 371, the connecting ring 37 is an annular sheet structure, the inner surface of the connecting ring 37 is fixedly connected to the outer surface of the center injection tube 3, and the connecting steel sheet 371 is fixedly installed on the outer surfaces of both sides of the connecting ring 37, and the connecting ring 37 is adapted to the distribution position of the connecting cam 363;

[0050] In this embodiment, if Fig. 9 and Figure 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 Figure 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 up by the poured epoxy resin material, and the floating plate 352 touches the floating rod 35 to rise, so that the conical blocking block 351 is lifted synchronously, and the conical blocking block 351 completely blocks the input end of the shunt pipe 1 31, and the injection material is discharged through the input ports of the shunt pipe 2 32 and the shunt pipe 3 33. At this time, the injection material will first fill the annular injection flat pipe 2 321 and then be discharged;

[0055] Step 4: When the material discharged from the array discharge pipe 34 at the lower end of the annular injection flat pipe 2 321 covers the material first poured in the center, the floating plate 352 rises to a certain extent again under the influence of the injection, so as to block the input port of the second branch pipe 32. Finally, when the mold cavity is completely poured, the input port of the third branch pipe 33 is blocked. At this time, the central injection pipe 3 is blocked by the conical blocking block 351, and the feeding is stopped and the delivery pump is turned off.

[0056] Step 5. During the upward floating of the floating plate 352, 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. 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. The floating height of the floating plate 352 is determined by the rotation angle formed by the pointer and the display dial 364, and the blocking position of the conical blocking block 351 is determined in this way. Finally, the casting material is cooled and formed. After the upper mold base 12 is separated from the lower mold base 11, the formed GLS insulator can be ejected by the ejection mold mechanism to facilitate the next casting.
