Description

Technical Field

[0001] This utility model relates to the field of insulating core rod technology, specifically to a mold disassembly device. Background Technology

[0002] Insulating core rods, as key components of high-voltage power grid support insulators, are widely used in the industry due to their outstanding characteristics such as light weight, strong corrosion resistance, and excellent insulation performance. In their production process, the disassembly of the relevant molds during the injection molding process is a critical step. Because the cured adhesive can stick to the mold's connecting parts, each connecting part of the mold needs to be heated before disassembly. This not only increases the labor intensity of the workers but also easily leads to safety accidents.

[0003] Currently, the disassembly of insulating core rod molds mainly relies on heating the mold with a heater to melt the cured adhesive, followed by disassembly using large-diameter pipe wrenches. However, large-diameter pipe wrenches are large in size and correspondingly heavy, which greatly increases the labor intensity of operators when using the wrenches for extended periods and easily leads to crushing accidents due to improper operation. In addition, the high temperature of the heated mold further increases the safety risks during the operation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a mold disassembly device to solve the technical problem mentioned in the background art, which is that the labor intensity of operators increases sharply when using pipe wrenches for a long time, and that improper operation can easily lead to crushing accidents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mold disassembly device includes a collar detachably disposed on the outer periphery of a mold. The collar is threadedly connected to a locking bolt. A first anti-slip plate and a second anti-slip plate are symmetrically arranged inside the collar. The first anti-slip plate is rotatably connected to the locking bolt. A guide rod is fixedly disposed on the first anti-slip plate and slidably connected to the collar. The second anti-slip plate is fixedly connected to the collar. The collar is provided with two symmetrically arranged movable rods. A third anti-slip plate is fixedly disposed on one end of each of the two movable rods extending to one end of the collar. The collar is provided with a drive assembly for driving the movable rods to move toward the mold.

[0006] Furthermore, the drive assembly includes two fixed plates fixedly disposed on the outside of the collar and symmetrically arranged, an adjusting bolt threadedly connected to the fixed plates, and a wedge block rotatably disposed at the bottom of the adjusting bolt. The movable rod has a slot, and one side of the slot has an inclined surface. The inclined surface in the slot slides in cooperation with the corresponding wedge block to push the movable rod toward the mold.

[0007] Furthermore, a baffle is fixedly provided on the movable rod, and a spring is fixedly provided between the baffle and the collar.

[0008] Furthermore, a receiving roller is movably inserted inside the mold, and an adjustment component for adjusting the height of the receiving roller is provided on one side of the mold.

[0009] Furthermore, the adjustment assembly includes a base plate and an electro-hydraulic push rod fixedly mounted on the top of the base plate. A mounting block is fixedly mounted on the top of the electro-hydraulic push rod, and the mounting block is fixedly connected to the receiving roller.

[0010] Furthermore, the first, second, and third anti-slip plates are all coated with an anti-slip coating on the side closest to the mold.

[0011] The beneficial effects of this utility model are as follows: By setting up a collar, locking bolt, first anti-slip plate, second anti-slip plate, movable rod, and third anti-slip plate, when disassembling the mold, the collar is placed on the mold, and the locking bolt is rotated to drive the first anti-slip plate to move downward and abut against the inner tube of the mold; the locking bolt is continued to be rotated, which drives the second anti-slip plate to move upward through the collar. After the first and second anti-slip plates respectively abut against the inner tube, the movable rod is then pushed towards the mold by the drive assembly. When the movable rod moves, it drives the third anti-slip plate to abut against the inner tube of the mold, thereby fixing the collar. Then, the collar is driven to move by the movable rod, and the movement of the collar pulls the inner tube of the mold out of the outer tube, thus completing the disassembly operation of the mold. This reduces the labor intensity of operators disassembling the mold with pipe wrenches and reduces safety hazards. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figures 1-4 As shown, a mold disassembly device includes a collar 2 detachably mounted on the outer periphery of a mold 1. The mold 1 includes an outer tube 11 and an inner tube 12 movably sleeved along its axial direction. The collar 2 is sleeved on one end of the inner tube 12, and a locking bolt 21 is threadedly connected to the top of the collar 2, with the locking bolt 21 vertically passing through the collar 2. A first anti-slip plate 22 and a second anti-slip plate 24, arranged symmetrically one above the other, are installed inside the collar 2. The first anti-slip plate 22 is rotatably connected to the locking bolt 21. Two guide rods 23, arranged symmetrically, are fixedly mounted on the top of the first anti-slip plate 22. Both guide rods 23 pass upward through the collar 2 and are slidably connected to the collar 2. The slidable connection between the guide rods 23 and the collar 2 prevents the first anti-slip plate 22 from rotating with the locking bolt 21. The second anti-slip plate 24 is fixedly connected to the collar 2.

[0016] When disassembling mold 1, first heat the mold 1 to be disassembled, then move it to the fixed vise 4 and clamp it. Next, put the collar 2 on the mold 1, and rotate the locking bolt 21 to move the first anti-slip plate 22 downward and abut against the inner tube 12 of the mold 1; continue to rotate the locking bolt 21, which drives the second anti-slip plate 24 upward through the collar 2. When the first anti-slip plate 22 and the second anti-slip plate 24 respectively abut against the inner tube 12, the initial fixation between the collar 2 and the inner tube 12 is completed; then rotate the collar 2 by the movable rod 5. The collar 2 will drive the inner tube 12 of the mold 1 to rotate synchronously with the first anti-slip plate 22 and the second anti-slip plate 24, so that the glue between the inner tube 12 and the outer tube 11 of the mold 1 breaks. Then, the collar 2 is moved by the movable rod 5. The movement of the collar 2 pulls the inner tube 12 out of the outer tube 11, thus completing the disassembly operation of mold 1.

[0017] Two symmetrically arranged movable rods 5 are slidably mounted on the collar 2. Both movable rods 5 pass through the collar 2, and a third anti-slip plate 51 is fixedly installed at one end of each movable rod 5 extending into the collar 2. The first anti-slip plate 22, the second anti-slip plate 24, and the third anti-slip plate 51 are all arc-shaped and adapted to the inner tube 12 to prevent insufficient contact between the first anti-slip plate 22, the second anti-slip plate 24, and the third anti-slip plate 51 and the inner tube 12. The side of the first anti-slip plate 22, the second anti-slip plate 24, and the third anti-slip plate 51 closest to the mold 1 is coated with an anti-slip coating, which is a silicon carbide coating, used to increase the friction between the first anti-slip plate 22, the second anti-slip plate 24, and the third anti-slip plate 51 and the inner tube 12. Furthermore, the length of the movable rods 5 is moderate to avoid excessive temperature at the end of the movable rod 5 away from the collar 2 due to heat transfer, or to avoid affecting operational convenience due to excessive length.

[0018] like Figure 3 and Figure 4As shown, the collar 2 is equipped with a drive assembly that drives the movable rod 5 to move toward the mold 1. The drive assembly includes two fixed plates 6 fixedly mounted on the outside of the collar 2 and symmetrically arranged, an adjusting bolt 61 threadedly connected to the fixed plates 6, and a wedge block 62 rotatably mounted on the bottom of the adjusting bolt 61. The adjusting bolt 61 is vertically inserted into the corresponding fixed plate 6. The top of the movable rod 5 has a slot 63, and the wedge block 62 slides in engagement with the slot 63. The slot 63 has an inclined surface on the side near the collar 2, and the inclined surface in the slot 63 slides in engagement with the corresponding wedge block 62 to push the movable rod 5 toward the mold 1. A baffle 52 is fixedly mounted on the bottom of the movable rod 5, and a spring 53 is fixedly mounted between the baffle 52 and the collar 2.

[0019] After the initial fixing of the collar 2 to the mold 1 with disassembly is completed, the adjusting bolts 61 on both sides of the collar 2 are turned. The adjusting bolts 61 drive the wedge block 62 to move downward. The wedge block 62 moves downward and engages with the inclined surface in the slot 63, thereby pushing the movable rod 5 to move horizontally towards the mold 1. At the same time, the spring 53 is compressed, which facilitates the subsequent reset of the movable rod 5. When the movable rod 5 moves, it drives the third anti-slip plate 51 to abut against the inner tube 12 of the mold 1, thereby further fixing the collar 2 and increasing the friction between the collar 2 and the inner tube 12 of the mold 1, so as to prevent relative rotation between the collar 2 and the inner tube 12 of the mold 1 when the collar 2 is rotated.

[0020] like Figure 1 As shown, a receiving roller 34 is movably inserted into the inner part of the mold 1. An adjustment assembly for adjusting the height of the receiving roller 34 is provided on one side of the mold 1. The adjustment assembly includes a base plate 3 and an electro-hydraulic push rod 32 fixedly installed on the top of the base plate 3. Four casters 31 are installed at the bottom corners of the base plate 3 to facilitate movement. A mounting block 33 is fixedly installed at the top of the electro-hydraulic push rod 32, and the mounting block 33 is fixedly connected to the receiving roller 34, with the receiving roller 34 fixedly inserted inside the mounting block 33. When disassembling the mold 1, the collar 2 is first fixed to the mold 1. Then, the receiving roller 34 is inserted into the inner tube 12 of the mold 1. Next, the electro-hydraulic push rod 32 is activated, and the height of the receiving roller 34 is adjusted so that it contacts the top wall of the inner tube 12 of the mold 1. During the subsequent extraction of the inner tube 12 from the outer tube 11, the inner tube 12 is lifted by the receiving roller 34. This prevents the inner tube 12 from falling and damaging the mold 1, and also prevents injury to workers. In addition, by adjusting the height of the receiving roller 34, the disassembly process of the inner tube 12 of the mold 1 can be made easier and more convenient.

[0021] Working principle: When disassembling mold 1, first heat the mold 1 to be disassembled, then move it to the fixed vise 4 and clamp it. Next, the collar 2 is placed on the mold 1, and the locking bolt 21 is rotated to move the first anti-slip plate 22 downward and abut against the inner tube 12 of the mold 1. The locking bolt 21 is rotated again, which drives the second anti-slip plate 24 upward through the collar 2. When the first anti-slip plate 22 and the second anti-slip plate 24 abut against the inner tube 12 respectively, the initial fixation between the collar 2 and the inner tube 12 is completed. Then, by turning the adjusting bolts 61 on both sides of the collar 2, the adjusting bolts 61 drive the wedge block 62 downward. The wedge block 62 moves downward and slides into the inclined surface in the slot 63, thereby pushing the movable rod 5 towards the mold 1 and compressing the spring 53. When the movable rod 5 moves, it drives the third anti-slip plate 51 to abut against the inner tube 12 of the mold 1, thereby further fixing the collar 2 and increasing the friction between the collar 2 and the inner tube 12 of the mold 1, so as to prevent relative rotation between the collar 2 and the inner tube 12 of the mold 1 when the collar 2 is rotated.

[0022] Next, the base plate 3 is moved to drive the receiving roller 34 into the inner tube 12 of the mold 1. The electric hydraulic push rod 32 is activated, and the height of the receiving roller 34 is adjusted so that it contacts the top wall of the inner tube 12 of the mold 1. Then, the movable rod 5 rotates the collar 2. The collar 2, with the help of the first anti-slip plate 22, the second anti-slip plate 24, and the third anti-slip plate 51, drives the inner tube 12 of the mold 1 to rotate synchronously, causing the adhesive between the inner tube 12 and the outer tube 11 of the mold 1 to break. Afterward, the movable rod 5 drives the collar 2 to move. During the process of the collar 2 pulling the inner tube 12 of the mold 1 out of the outer tube 11, the inner tube 12 is supported by the receiving roller 34. This not only prevents the inner tube 12 from falling and damaging the inner tube 12 of the mold 1, but also prevents injury to the operator. When the inner tube 12 of the mold 1 is completely pulled out, the disassembly operation of the mold 1 is completed, thereby reducing the labor intensity of the operator when using pipe wrenches to disassemble the mold 1 and reducing safety hazards.
