Description

Technical Field

[0001] This utility model relates to the field of demolding tools, and in particular to a novel cross-linking demolding tool. Background Technology

[0002] A crosslinking mold is a type of mold used in the three-layer co-extrusion process of crosslinked polyethylene (XLPE). This co-extrusion process involves sequentially applying a conductor shielding layer, an insulation layer, and an insulation shielding layer to the outside of the conductor. Correspondingly, a set of crosslinking molds consists of three parts: the core, the middle mold, and the mold sleeve. These molds are collectively referred to as crosslinking molds. Before starting the machine, the crosslinking mold is screwed onto the crosslinking distributor and fixed in place. After stopping the machine, it is disassembled. The crosslinking mold is generally made of 42CrMo or 42CrMo4V, which has high hardness but is relatively brittle. Directly striking the crosslinking mold will cause structural damage. Moreover, in order to ensure the stability of the crosslinking material when it flows across the surface and avoid accumulation, the surface of the crosslinking mold is very smooth, so there are no sharp parts that can be used for leverage. Therefore, only demolding tools can be used.

[0003] Currently, in order to facilitate disassembly after shutdown, refer to Figure 1 As shown, there are typically 12 recessed disassembly flats at the disassembly port on the outside of the mold. During disassembly, the corresponding demolding tool is first engaged with the disassembly flats, and then the demolding tool is tapped externally to rotate the crosslinking mold in the reverse direction, finally removing the crosslinking mold. This significantly improves the probability of damage to the crosslinking mold. However, during the tapping disassembly process, due to incomplete contact between the demolding tool and the disassembly flats, the demolding tool is prone to slippage at the contact point with the crosslinking mold. Repeated slippage not only makes the disassembly work more difficult but also damages the crosslinking mold and the demolding tool, leading to unnecessary wear and tear. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the slippage phenomenon at the contact position between the demolding tool and the crosslinking mold in the prior art, which not only makes the knocking and disassembly work difficult but also causes damage to the crosslinking mold. In this way, a new type of crosslinking demolding tool is provided, which can still lock the contact point between the demolding tool and the crosslinking mold when knocking and disassembling, without relative slippage, to ensure that the demolding tool can be smoothly removed from the crosslinking mold and to avoid scratching the crosslinking mold.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel crosslinking mold removal tool for disassembling a crosslinking mold. The crosslinking mold has a disassembly opening, and the exterior of the disassembly opening has a recessed disassembly flat section. The mold removal tool includes...

[0006] The kit is fitted over the disassembly port of the crosslinking mold. The inner wall of the kit is provided with a disassembly flat part, which is close to the recessed disassembly flat part. The surface of the disassembly flat part is provided with an anti-slip structure, and the hardness of the anti-slip structure is less than the hardness of the disassembly flat part. The outer wall of the kit is provided with protrusions.

[0007] In one embodiment of this utility model, the kit is configured as a cylindrical structure.

[0008] In one embodiment of the present invention, the protrusion extends radially along the cylindrical structure.

[0009] In one embodiment of this utility model, the protrusion and the disassembly flat position are respectively located at both ends of the cylinder.

[0010] In one embodiment of the present invention, a plurality of protrusions are further included, and the plurality of protrusions are respectively disposed opposite to both sides of the cylindrical body.

[0011] In one embodiment of the present invention, a plurality of disassembly flat positions are included, and the plurality of disassembly flat positions are evenly distributed along the circumference of the cylinder.

[0012] In one embodiment of the present invention, the anti-slip structure is configured as uniformly distributed vertical stripes that extend along the axial direction of the cylinder.

[0013] In one embodiment of this utility model, the protrusion is configured as a strip-shaped lever arm, the length of which is greater than the diameter of the cylinder, and mounting holes are provided on both sides of the cylinder. The strip-shaped lever arm passes through the mounting holes on both sides and penetrates the cylinder.

[0014] In one embodiment of this utility model, the strip lever arm is welded to the cylinder.

[0015] In one embodiment of this utility model, the edges of adjacent disassembly flat sections are connected to each other.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The novel crosslinking mold removal tool of this utility model features protrusions on the outer wall of the kit, which facilitates external impact on the kit, causing it to rotate and reducing the impact of external impact on the crosslinking mold. The anti-slip structure increases the friction between the disassembly flat section and the crosslinking mold, preventing slippage and ensuring smooth disassembly. The anti-slip structure has a lower hardness than the disassembly flat section, allowing it to deform even with slight deformation of the tool, preventing scratches on the crosslinking mold.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 As shown, in one embodiment of this utility model, a novel crosslinking demolding tool is disclosed, which is used to disassemble a crosslinking mold. The crosslinking mold has a disassembly opening, and the exterior of the disassembly opening has 12 evenly distributed recessed disassembly flats 8. The demolding tool includes...

[0026] Kit 1 is used to fit over the disassembly port of the crosslinking mold and receive impacts from external forces, preventing direct damage to the crosslinking mold from external forces. The inner wall of kit 1 has a milled disassembly flat 2, which can be considered as a rectangular plane parallel to the axis of the disassembly port. The disassembly flat 2 is set and interlocked with the recessed disassembly flat 8, allowing the demolding tool to drive the crosslinking mold to rotate. To drive the demolding tool to rotate, the outer wall of kit 1 has a protrusion 3 to receive impacts from external forces. The disassembly flat 2 is close to the recessed disassembly flat 8. The surface of the disassembly flat 2 is connected to an anti-slip structure, and the hardness of the anti-slip structure is less than that of the disassembly flat 2. The anti-slip structure interlocks with the recessed disassembly flat 8. In this way, when the demolding tool undergoes slight deformation, the anti-slip structure can undergo slight deformation, preventing scratches to the crosslinking mold. Kit 1 and disassembly flat 2 are preferably made of iron, and the anti-slip structure is preferably made of copper.

[0027] Reference Figure 1 As shown, the kit 1 is further configured as a cylindrical structure, the inner diameter of which is slightly larger than the diameter of the disassembly port, and can be fitted onto the disassembly port. The cylindrical structure has the characteristics of high structural strength and stability, can withstand greater impact force, and is not easily deformed.

[0028] Reference Figure 1 As shown, the protrusion 3 extends radially along the cylindrical structure in order to increase the length of the lever arm and save the external force required to strike the protrusion 3.

[0029] Reference Figure 1 As shown, the protrusion 3 and the disassembly flat position 2 are located at the upper and lower ends of the cylinder, respectively. Since the lower end 4 of the cylinder is connected to the disassembly port, setting the protrusion 3 at the upper end 5 can allow striking tools such as copper hammers to avoid the disassembly port and prevent accidental impact on the crosslinking mold.

[0030] Reference Figure 1 As shown, it further includes two protrusions 3, which are respectively positioned opposite each other on both sides of the cylinder. The two protrusions 3 rotate with the cylinder and can provide multiple striking points, saving the operator time from frequently switching striking directions.

[0031] Reference Figure 1 As shown, further, in order to improve the clamping degree of the demolding tool and the crosslinking mold and reduce the slippage phenomenon, 12 demolding flat positions 2 are included. The 12 demolding flat positions 2 are evenly distributed along the circumference of the cylinder, and the 12 demolding flat positions 2 are set one-to-one with the 12 recessed demolding flat positions 8 of the crosslinking mold.

[0032] Reference Figure 1As shown, the anti-slip structure is configured as a number of evenly distributed vertical stripes 6 made of copper. The vertical stripes 6 are evenly distributed along the circumference of the cylindrical structure. The vertical stripes 6 are welded to the surface of the disassembly flat position 2, and the vertical stripes 6 extend along the axial direction of the cylindrical body. Since the disassembly port is inserted into the cylindrical body along the circumference, the vertical stripes 6 can reduce the resistance of the cross-linking mold to the demolding tool, making it easier to install and disassemble the demolding tool.

[0033] Reference Figure 1 As shown, the two protrusions 3 can be combined into one, such as by extending the protrusion 3 into a strip-shaped lever arm. The length of the strip-shaped lever arm is greater than the diameter of the cylinder, and mounting holes 7 are provided on both sides of the cylinder. In this way, when the strip-shaped lever arm passes through the mounting holes 7 on both sides and penetrates the cylinder, two striking points can be formed on both sides of the cylinder structure. The insertion of the strip-shaped lever arm and the cylinder also makes it easier for the operator to install and disassemble the strip-shaped lever arm separately, reducing the assembly difficulty.

[0034] Reference Figure 1 As shown, in another embodiment, in order to protect the demolding tool, the strip arm is welded to the cylinder as a whole.

[0035] Reference Figure 1 As shown, the cross-section of the lever arm is rectangular to reduce slippage when striking tools such as copper hammers strike the lever arm.

[0036] Reference Figure 1 As shown, furthermore, in order to increase the area of ​​the disassembly flat section 2 and improve the continuity of the disassembly flat section 2, the edges of adjacent disassembly flat sections 2 are connected to each other.

[0037] The working principle of the novel crosslinking demolding tool described in this utility model is as follows:

[0038] After stopping the machine, hold the bar arm or cylinder and align the lower end 4 of the cylinder with the disassembly port, ensuring that the 12 disassembly flats 2 are precisely aligned with the 12 recessed disassembly flats 8 of the crosslinking mold. Then, place the demolding tool on the disassembly port of the crosslinking mold and tap the bar arm circumferentially with a hard tool such as a copper rod, causing the demolding tool to rotate the crosslinking mold in the opposite direction until the crosslinking mold and the crosslinking fluid are completely separated. When the demolding tool undergoes slight deformation, the anti-slip structure can undergo slight deformation to avoid scratching the crosslinking mold.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
