Description

Technical Field

[0001] This application relates to the field of insulator production and processing technology, and in particular to an insulator tail mold demolding device. Background Technology

[0002] An insulator is a special type of insulating component that plays a crucial role in overhead power transmission lines. In the past, insulators were primarily used on utility poles. Gradually, they evolved into disc-shaped insulators hung at one end of high-voltage power line towers to increase creepage distance. These are typically made of glass or ceramic and are called insulators. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions; otherwise, they will not function effectively and will impair the service life and operational life of the entire power line.

[0003] Currently, the insulator manufacturing process typically includes steps such as casting, demolding, and drying. During casting, a tight connection is formed between the insulator and the tail mold to ensure the structural stability after molding. With the increasing demand for electricity, the production efficiency and quality requirements of insulators are constantly improving. Traditional manual demolding methods are no longer sufficient to meet the needs of large-scale production and therefore require improvement. Utility Model Content

[0004] To facilitate demolding of the molded insulators, reduce labor intensity, and improve production efficiency, this application provides an insulator tail mold demolding device.

[0005] The insulator tail mold demolding device provided in this application adopts the following technical solution:

[0006] An insulator tail mold release device includes a support frame, a positioning seat, a lifting assembly, and a tail mold clamping assembly. The positioning seat is disposed on the support frame and has a positioning groove for positioning the tail mold of the insulator. The tail mold clamping assembly is located near the positioning seat and is used to clamp the tail mold of the insulator. The lifting assembly is disposed on the support frame and is used to lift the insulator after clamping the tail mold.

[0007] By adopting the above technical solution, during demolding, the operator first inserts the lower end of the insulator into the positioning seat, so that the tail mold is in the positioning groove. Next, the tail mold clamping assembly clamps the tail mold of the insulator. Finally, the lifting assembly is driven, which moves the insulator vertically upwards. With the combined lifting force of the lifting assembly and the clamping force of the tail mold clamping assembly, the insulator is demolded. The entire demolding device has high demolding efficiency, significantly shortening demolding time; the demolding process is stable, avoiding damage to the insulator; the equipment structure is simple, and maintenance costs are low.

[0008] Preferably, the tail mold clamping assembly includes a first driving member and a clamping block. The first driving member is connected to the clamping block and is used to drive the clamping block to press onto the tail mold. The tail mold clamping assembly is symmetrically arranged in two sets, and the two clamping blocks together clamp the tail mold.

[0009] By adopting the above technical solution, the first driving component controls the clamping blocks to move along the direction closer to the tail mold, and the two clamping blocks clamp the tail mold, thus fixing the tail mold. The first driving component is a first cylinder or an electric push rod. The piston rod of the first cylinder has a stroke control mechanism, which can control the cylinder piston rod to stop at a predetermined position, realizing precise mechanical actions (such as clamping, pushing, lifting, etc.) and providing continuous, stable and reliable pressure. Typical stroke control mechanisms include, but are not limited to, mechanical stops, magnetic switches with solenoid valves, and displacement sensors with controllers. These are existing technologies and will not be elaborated here.

[0010] Preferably, the clamping block has a slot that is adapted to the shape of the outer surface of the tail mold.

[0011] By adopting the above technical solution, the design of the slot can increase the contact area between the clamping block and the tail mold, improve the clamping force of the clamping block to clamp the tail mold, and ensure the demolding effect of the tail mold.

[0012] Preferably, the lifting assembly includes a second driving member and a top plate. The top plate is located directly above the positioning seat and has a clearance hole for the insulator to pass through. The top plate is used to support the insulator. The second driving member is connected to the top plate and is used to control the up and down movement of the top plate.

[0013] By adopting the above technical solution, the insulator generally has a shape that is wider at the top and narrower at the bottom, with the tail mold located at the narrow end. After the tail mold clamping assembly clamps the tail mold, the second driving component controls the top plate to move vertically upward. Under the action of the top plate, the insulator is lifted, and the insulator and the tail mold tend to move away from each other, thus achieving demolding.

[0014] Preferably, it further includes a connecting plate and a plurality of connecting rods, the connecting plate being connected to the second driving component, the connecting plate being connected to the top plate via the connecting rods, and the connecting rods being spaced apart; a limiting groove is correspondingly provided on the support frame, and the connecting rods pass through the limiting groove.

[0015] By adopting the above technical solution, the second driving component drives the connecting plate to rise and fall, and under the connection of each connecting rod, it can synchronously drive the top plate to move up and down. The connecting rods are always limited by the limiting grooves during the lifting process, which can improve the stability of the top plate during movement.

[0016] Preferably, a pair of fixing blocks are connected to the top plate. The two fixing blocks are arranged opposite to each other and close to the clearance hole. An arc-shaped groove is provided on the fixing block. The two fixing blocks are used to limit the position of the insulator.

[0017] By adopting the above technical solution, the two fixing blocks can limit the position of the insulator and increase the contact area between the top plate and the insulator, so that the top plate can better apply force to the insulator.

[0018] Preferably, it further includes a worktable, a rotating assembly, and a collection box. The support frame is rotatably connected to the worktable. The rotating assembly is connected to the support frame and is used to control the rotation of the support frame. The rotation axis of the support frame is in the horizontal direction. The collection box has an opening and is located on the rotation path of the top plate. The collection box is used to receive the insulator after it is ejected.

[0019] By adopting the above technical solution, after the insulator is demolded from the tail mold, the entire support frame can be rotated using the rotating component to change the orientation of the top plate, so that the insulator on the top plate can fall into the collection box under the action of gravity, thus realizing the unloading.

[0020] Preferably, the rotating assembly includes a rotating motor and a connecting plate. The rotating motor is mounted on the worktable, and the connecting plate is mounted on the support frame and connected to the output shaft of the rotating motor.

[0021] By adopting the above technical solution, the connecting plate connects the rotary motor and the support frame together. When the rotary motor is running, it can drive the entire support frame to rotate, so that the top plate can rotate in the direction closer to the collection box.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) By setting up a positioning seat, a lifting assembly, and a tail mold clamping assembly, the lower end of the insulator is inserted into the positioning seat, so that the tail mold is in the positioning groove; then the tail mold clamping assembly is used to clamp the tail mold of the insulator; finally, the lifting assembly is driven, which can drive the insulator to move vertically upward. Under the cooperation of the lifting force of the lifting assembly and the clamping force of the tail mold clamping assembly, the insulator is demolded. The entire demolding device has high demolding efficiency and can significantly shorten the demolding time.

[0024] (2) By setting a slot on the clamping block, the design of the slot can increase the contact area between the clamping block and the tail mold, improve the clamping force of the clamping block to clamp the tail mold, and ensure the demolding effect of the tail mold.

[0025] (3) By setting up a rotating component and a collection box, after the insulator has completed the demolding of the tail mold, the rotating component can be used to drive the entire support frame to rotate, change the orientation of the top plate, and facilitate the insulator on the top plate to fall into the collection box under the action of gravity, thus realizing the unloading.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0035] Example 1

[0036] This application discloses an insulator tail mold release device. (Refer to...) Figure 1 and Figure 2 The demolding device includes a support frame 1, a positioning seat 2, a lifting assembly 3, and a tail mold clamping assembly 4. The support frame 1 serves as the carrier, and the positioning seat 2 is fixedly mounted on the support frame 1 using bolts. The positioning seat 2 has a positioning groove 5 for positioning the tail mold of the insulator. The tail mold clamping assembly 4 is located near the positioning seat 2 and is used to clamp the tail mold of the insulator. The lifting assembly 3 is mounted on the support frame 1 and is used to lift the insulator after the tail mold is clamped.

[0037] Specifically, the tail mold clamping assembly 4 includes a first driving member 41 and a clamping block 42. The first driving member 41 is connected to the clamping block 42 and is used to drive the clamping block 42 to press against the tail mold. The first driving member 41 is a linear actuator such as a first cylinder or an electric push rod. Two sets of tail mold clamping assemblies 4 are symmetrically arranged, with the two clamping blocks 42 arranged opposite each other, and used together to clamp the tail mold. The clamping block 42 has a slot 6, which is adapted to the shape of the outer surface of the tail mold. The slots 6 on the two clamping blocks 42 are arranged opposite each other, and the tail mold is located between the two slots 6.

[0038] The lifting assembly 3 includes a second driving member 31 and a top plate 32. The top plate 32 is located directly above the positioning seat 2 and has a clearance hole 7. The clearance hole 7 is located above the positioning groove 5 and is used for the insulator to pass through. The top plate 32 is used to support the insulator. The second driving member 31 is located below the positioning seat 2 and is connected to the top plate 32. The second driving member 31 is used to control the vertical movement of the top plate 32. In this embodiment, the second driving member 31 is a second cylinder. A connecting plate 8 is fixedly connected to the piston rod of the second cylinder. The connecting plate 8 and the top plate 32 are parallel to each other and are connected together by several connecting rods 9. There are four connecting rods 9. Each connecting rod 9 is vertically arranged and spaced apart. A corresponding number of limiting grooves 10 are opened on the support frame 1, and each connecting rod 9 passes through each limiting groove 10. The second driving member 31 drives the connecting plate 8 to rise and fall. Under the connection of each connecting rod 9, the top plate 32 can be moved up and down synchronously. The connecting rod 9 is always limited by the limiting groove 10 during the lifting process, which can improve the stability of the top plate 32 when it moves.

[0039] Insulators are generally wider at the top and narrower at the bottom, with the tail mold located at the narrower end. During demolding, the operator first inserts the lower end of the insulator into the positioning seat 2, positioning the tail mold within the positioning groove 5. Then, the first driving component 41 controls the clamping blocks 42 to move towards the tail mold, clamping them together to secure the tail mold. The design of the slot 6 increases the contact area between the clamping blocks 42 and the tail mold, enhancing the clamping force and ensuring effective demolding.

[0040] After the tail mold clamping assembly 4 clamps the tail mold, the second driving component 31 controls the top plate 32 to move vertically upward. The insulator is lifted by the top plate 32, and the insulator and the tail mold tend to move away from each other, thus achieving demolding.

[0041] In addition, a pair of fixing blocks 11 are fixedly connected to the surface of the top plate 32. The two fixing blocks 11 are horizontally opposite each other and are close to the clearance hole 7. An arc-shaped groove 12 is formed on the side of the fixing block 11 near the clearance hole 7, and the clearance hole 7 is located between the two arc-shaped grooves 12. The two fixing blocks 11 are used to limit the insulator. The two fixing blocks 11 can limit the insulator and increase the contact area between the top plate 32 and the insulator, so that the top plate 32 can better apply force to the insulator.

[0042] The implementation principle of the insulator tail mold demolding device according to this application embodiment is as follows: During demolding, the operator first inserts the lower end of the insulator into the positioning seat 2, so that the tail mold is in the positioning groove 5. Then, the tail mold clamping assembly 4 is operated to clamp the tail mold of the insulator. Finally, the lifting assembly 3 is driven, which can drive the insulator to move vertically upward. Under the cooperation of the lifting force of the lifting assembly 3 and the clamping force of the tail mold clamping assembly 4, the insulator is demolded. The entire demolding device has high demolding efficiency and can significantly shorten the demolding time; the demolding process is stable and avoids damage to the insulator.

[0043] Example 2

[0044] Combination Figure 3 The difference between Embodiment 2 and Embodiment 1 is that the demolding device further includes a worktable 13, a rotating assembly 14, and a collection box 15. The worktable 13 is fixedly installed on the ground, and the support frame 1 is rotatably connected to the worktable 13. The rotation axis of the support frame 1 is horizontal. The rotating assembly 14 is connected to the support frame 1 and is used to control the rotation of the support frame 1. The collection box 15 is rectangular and has an opening. The collection box 15 is located on the rotation path of the top plate 32 and is used to receive the insulators after they have been ejected by the lifting assembly 3. The rotating assembly 14 includes a rotating motor 141 and a connecting plate 142. The rotating motor 141 is installed on the worktable 13, and the connecting plate 142 is fixedly connected to the support frame 1 and connected to the output shaft of the rotating motor 141. The rotating motor 141 is used to drive the entire support frame 1 to rotate. The output shaft of the rotating motor 141 has a self-locking function. The self-locking structure can adopt existing technical means, such as worm gear transmission self-locking, electromagnetic brakes, and ratchet and pawl mechanisms.

[0045] After the insulator is demolded from the tail mold, the rotating component 14 can be used to drive the entire support frame 1 to rotate, changing the orientation of the top plate 32, so that the insulator on the top plate 32 can fall into the collection box 15 under the action of gravity, thus realizing the unloading.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
