Description

Technical Field

[0001] The utility model relates to the field of solid-sealed pole production, in particular to a demoulding tool for solid-sealed poles. Background Art

[0002] The solid-sealed pole is an independent component that encapsulates the vacuum interrupter, conductive connection and / or terminal with solid insulating materials. Specifically, it is to embed the vacuum interrupter (Vacuuminterruptor) and the related conductive parts of the circuit breaker (Circuit-breaker) into easily solidified solid insulating materials such as epoxy resin or thermoplastic materials to form a pole, making the entire circuit breaker pole an integral component.

[0003] The mainstream casting process of solid-sealed poles on the market is usually the APG casting process, which is to thermoform the epoxy curing material through the mold, inject the epoxy curing material into the mold under a certain injection pressure and maintain the pressure, and then solidify and demold after the process time is reached, and the product is demolded and taken out. For conventional solid-sealed poles with upper and lower outlets in the horizontal direction, the mold is usually divided into two forms according to the product's requirements for the parting line. One of them is that the dynamic and static molds each contain half of the product, and the upper and lower outlet die head structures also occupy half of the dynamic and static molds.

[0004] However, due to the requirements of the product on the position of the parting line, the upper and lower outlet dies must be arranged perpendicular to the static mold direction. Some solid-sealed poles are heavy and require a robot to assist in demolding. After demolding, they are 90 degrees to the robot, making it impossible for the robot to directly clamp and demold. It is necessary to set up a demolding pad to support the product and turn it so that the robot can clamp and demold. However, conventional demolding pads are only simple tooling plates, and it is difficult to support the solid-sealed poles for rotation. Utility Model Content

[0005] The utility model aims to provide a demoulding tool for a sealed pole, aiming to improve the problem that it is difficult for a conventional demoulding pad to carry the sealed pole to rotate and the demoulding efficiency is poor.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A demoulding tool for a sealed pole, comprising an annular base and a tool body,

[0008] The annular base is provided with a clearance channel, the clearance channel connects the inner annular surface and the outer annular surface of the annular base, and the top of the annular base is provided with an arc-shaped slide rail;

[0009] A first avoidance groove extending inward is provided on one side of the tool body, and the first avoidance groove passes through the tool body in a vertical direction. A sliding component is provided on the bottom surface of the other side of the tool body, and the sliding component extends downward into the arc-shaped slide rail.

[0010] Furthermore, a push rod mechanism is fixed to the other side of the tool body.

[0011] Furthermore, the push rod mechanism includes a push block and a push rod, the push block is fixed to the middle part of the other side surface of the tooling body, and one end of the push rod is fixed to the push block.

[0012] Furthermore, a limiting block facing the annular base is fixed at the bottom of the push block, and the limiting block is tangent to the outer ring surface of the annular base.

[0013] Furthermore, an inclined yoke positioning assembly is fixed on the inner ring surface of the annular base, and the inclined yoke positioning assembly is in abutment contact with the side surface of the lower mold core of the mold.

[0014] Furthermore, the inclined weir positioning assembly includes two positioning blocks, and the two positioning blocks are symmetrically distributed on both sides of the clearance channel. The opposite sides of the two positioning blocks are inclined surfaces, and the two inclined surfaces are in an "eight" shape facing the clearance channel.

[0015] Furthermore, two groups of mutually spaced protruding positioning components are provided on the inner side surface of the arc-shaped slide rail, and the protruding positioning components are in abutment contact with the sliding components.

[0016] Furthermore, the protruding positioning assembly includes two protruding columns that are spaced apart from each other, and the two protruding columns respectively abut against the sliding assembly from two sides.

[0017] Furthermore, the sliding assembly includes a mounting block, the top surface of the mounting block is fixedly connected to the bottom surface of the tooling body, a connecting handle extending downward is fixed to the bottom surface of the mounting block, and the bottom end of the connecting handle is movably connected to a flexible pulley via a rotating shaft.

[0018] Furthermore, at least one sinking groove is provided on the top surface of the tool body, a second avoidance groove is provided in the sinking groove, the sinking groove and the second avoidance groove both correspond one-to-one to the bottom protrusion of the sealed pole, and the bottom protrusion extends into the second avoidance groove.

[0019] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0020] 1. The making way channel of the annular base makes way for the lower mold core of the mold. The tooling body is slidably set on the annular base through the sliding assembly. The sealed pole falls and is placed on the tooling body. The sealed pole is rotated and unloaded through the tooling body, and the position of the sealed pole is adjusted to facilitate the robot to clamp and demould, effectively improving the demoulding efficiency.

[0021] 2. During the installation of the annular base, the annular base is positioned by placing the oblique bead positioning assembly on the peripheral layer of the lower mold core of the mold and the bottom of the sealed pole through the give way channel. The oblique bead positioning assembly presses against the side of the lower mold core of the mold through its own oblique bead surface to position the annular base, thereby achieving the purpose of roughly positioning the tooling body located above the annular base and improving the demoulding accuracy.

[0022] 3. Two groups of raised positioning components are arranged in the annular slide rail, one group of raised positioning components limits the starting position of the tooling body, and the other group of tooling components limits the ending position of the tooling body, so as to ensure the accuracy of the tooling body at the starting position and ensure that the sealed pole can be accurately placed on the tooling body to avoid damage to the sealed pole.

[0041] Example

[0042] Please refer to Figures 1-9As shown, the present embodiment provides a demoulding tool for a sealed pole, comprising an annular base 1 and a tool body 2; a clearance channel 11 is provided on the annular base 1, and the clearance channel 11 connects the inner annular surface and the outer annular surface of the annular base 1. A bevel positioning assembly 13 is fixed on the inner annular surface of the annular base 1, and the bevel positioning assembly 13 is in abutment with the side surface of the lower mold core of the mold. A first avoidance groove 21 extending inward is provided on one side of the tool body 2, and the first avoidance groove 21 passes through the tool body 2 in the vertical direction. An arc-shaped slide rail 12 is provided on the top of the annular base 1; a sliding assembly 3 is provided on the bottom surface of the other side of the tool body 2, and the sliding assembly 3 extends downward into the arc-shaped slide rail 12. Two sets of mutually spaced protruding positioning assemblies 14 are provided on the inner side surface of the arc-shaped slide rail 12, and the protruding positioning assembly 14 is in abutment with the sliding assembly 3.

[0043] The clearance channel 11 of the annular base 1 makes way for the lower mold core of the mold. During the installation of the annular base 1, the clearance channel 11 is placed on the peripheral layer of the lower mold core of the mold and the bottom of the solid-sealed pole. The inclined bead positioning component 13 uses its own inclined bead surface to press against the side of the lower mold core of the mold to position the annular base 1, thereby achieving the purpose of roughly positioning the tooling body 2 located above the annular base 1. Furthermore, the tooling body 2 is slidably set on the annular base 1 through the sliding component 3, and the first avoidance groove 21 makes way for the lower mold core of the mold, so that the tooling body 2 can be accurately located directly below the solid-sealed pole. The solid-sealed pole falls and is placed on the tooling body 2, and the solid-sealed pole is rotated and discharged through the tooling body 2. At the same time, two groups of protruding positioning components 14 are arranged in the annular slide rail, one group of protruding positioning components 14 limits the starting position of the tooling body 2, and the other group of tooling components limits the ending position of the tooling body 2, thereby ensuring the accuracy of the tooling body 2 at the starting position and ensuring that the sealed pole can be accurately placed on the tooling body 2 to avoid damage to the sealed pole.

[0044] Please refer to Figures 1-5 and Figure 7 As shown, in this embodiment, a push rod mechanism 4 is fixed to the other side of the tooling body 2. Specifically, the push rod mechanism 4 includes a push block 41 and a push rod 42, the push block 41 is fixed to the middle of the other side of the tooling body 2, and one end of the push rod 42 is fixed to the push block 41. The push rod 42 provides a longer lever arm for employees, so that a small thrust can drive the sealed pole to rotate. Furthermore, a limit block 411 facing the annular base 1 is fixed to the bottom of the push block 41, and the limit block 411 is tangential to the outer annular surface of the annular base 1. The limit block 411 limits the tooling body 2 during the rotation process, ensuring that the tooling body 2 rotates along the extension direction of the arc-shaped slide rail 12, thereby ensuring the accuracy of the rotation position of the tooling body 2.

[0045] Please refer to Figure 6As shown, in this embodiment, the inclined yoke positioning assembly 13 includes two positioning blocks 131, and the two positioning blocks 131 are symmetrically distributed on both sides of the clearance channel 11. The opposite sides of the two positioning blocks 131 are inclined surfaces, and the two inclined surfaces are in an "eight" shape facing the clearance channel 11. The two relative positioning blocks 131 are pressed against the lower mold core of the mold from both sides, effectively ensuring the accuracy of the position of the annular base 1. In this embodiment, the positioning block 131 is integrally formed with the annular base 1, which effectively reduces the production difficulty and reduces the production cost. Similarly, the positioning block 131 can be detachably fixed on the inner ring surface of the annular base 1 by means of a clamping block or bonding, so as to realize the flexible replacement of the positioning block 131. According to the size of the lower mold core of different molds, positioning blocks 131 of different sizes and positioning blocks 131 of different inclinations can be flexibly selected to adapt to more molds, which has good practicality.

[0046] The size of the arc corresponding to the arc length between the two groups of raised positioning components 14 is the same as the angle that the sealed pole needs to rotate, and the two groups of raised positioning components 14 correspond to the starting point and end point of the rotation of the tooling body 2. In this embodiment, the size of the arc corresponding to the arc length between the two groups of raised positioning components 14 is 90°. Similarly, the size of the arc corresponding to the arc length between the raised positioning components 14 is set according to the angle between the sealed pole and the manipulator. In this embodiment, the raised positioning component 14 includes two spaced-apart protrusions 141, and the two protrusions 141 respectively abut against the sliding component 3 from both sides. The two protrusions 141 are spaced-apart to form a limit interval. When the sliding component 3 moves between the two protrusions 141, the two protrusions 141 limit the sliding component 3 from both sides, effectively ensuring the accuracy of the position of the tooling body 2. Please refer to Figure 1 and Figure 2 as well as Figure 3 and Figure 4 As shown, in the first state, the tool body 2 is inclined at 45° to the left side of the clearance channel 11. The first state is the initial state, for the sealed pole to fall and place; in the second state, the tool body 2 is inclined at 45° to the right side of the clearance channel 11, that is, from the first state to the second state, the tool body 2 rotates 90°, so as to drive the sealed pole to rotate 90°, which is convenient for the robot to grab and cut materials. The end of the tool body 2 in the figure is located at the mouth of the clearance channel 11 and is in a suspended state. Similarly, a support platform can be set at the mouth of the clearance channel 11 of the annular base 1 to support the end of the tool body 2 and ensure the stability of the sealed pole during the rotation process. Furthermore, an auxiliary universal wheel can be set on the bottom surface of the tool body 2. The auxiliary universal wheel reduces the friction between the tool body and the annular base 1, which is convenient for rotating the sealed pole.

[0047] Please refer to Figure 8 and Figure 9As shown in the figure, in this embodiment, the sliding assembly 3 includes a mounting block 31. The top surface of the mounting block 31 is fixedly connected to the bottom surface of the tooling body 2. A connecting handle 32 extending downward is fixed to the bottom surface of the mounting block 31. The bottom end of the connecting handle 32 is movably connected to a flexible pulley 34 through a rotating shaft 33. The flexible pulley 34 rotates within the arc-shaped slide rail 12 to realize the rotation of the tooling body 2 on the annular base 1. Specifically, the protruding height of the convex column 141 is within the range of the compressive deformation of the flexible pulley 34 in its thickness direction. During the positioning process, the flexible pulley 34 will press over the convex column 141, and the convex column 141 will cause extrusion on the flexible pulley 34. The thickness of the flexible pulley 34 itself is the extrusion range that the flexible pulley 34 can withstand, which limits the protruding height of the convex column 141 and the thickness of the flexible pulley 34, ensuring that the flexible pulley 34 can press over the convex column 141, enabling the flexible pulley 34 to enter between the two convex columns 141 for the convex column 141 to perform position-limiting, and preventing the rotation of the flexible pulley 34 from being affected.

[0048] Similarly, the radian size corresponding to the arc length of the arc-shaped slide rail 12 can be the same as the rotation angle size of the solid-sealed pole column, and the rotation angle of the tooling body 2 is directly limited by the arc length. The protruding positioning assembly 14 is reduced, and the cost is lowered. Similarly, in this embodiment, a relatively long arc-shaped slide rail 12 is provided, which effectively reduces the weight of the annular base 1, reduces the material consumption, and can rotate a larger angle to meet the blanking situation where the angle is not 90°.

[0049] Please refer to Figure 1 and Figure 3 As shown in the figure, at least one sinking groove 22 is formed on the top surface of the tooling body 2, and the sinking groove 22 effectively reduces the weight of the tooling body 2. A second avoidance groove 23 is formed in the sinking groove 22. The sinking groove 22 and the second avoidance groove 23 both correspond one-to-one to the bottom protrusions of the solid-sealed pole column, and the bottom protrusions extend into the second avoidance groove 23. In this embodiment, the number of both the sinking groove 22 and the second avoidance groove 23 is three. The second avoidance groove 23 avoids the bottom protrusions of the solid-sealed pole column, ensuring that the bottom of the solid-sealed pole column can stably contact the bottom surface of the tooling body 2, guaranteeing the stability of the solid-sealed pole column during the rotary blanking process, and preventing the solid-sealed pole column from tilting and collapsing during rotation.

[0050] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
