Description

Technical Field

[0001] This utility model relates to the field of eccentricity adjustment technology for wire extrusion molds, and in particular to a manual eccentricity adjustment mechanism for insulation layer extrusion molds. Background Technology

[0002] An insulated wire is a wire insulated by uniformly and sealedly wrapping a non-conductive material, such as resin, plastic, silicone rubber, or PVC, to form an insulating layer and prevent the conductor from coming into contact with the outside world, which could cause accidents such as leakage, short circuit, or electric shock. An extrusion die is a type of molding die, except that its material discharge method is achieved through the extrusion action.

[0003] Regarding the prior art patent CN119400521A, which discloses an eccentric adjustment device for a cable extruder, the device includes: a fixed base, which includes an outer base body and a ball head placement cavity with a concave front end; an outer hemispherical head inner die seat, which includes a tail hemispherical head and a forward-convex guide structure, wherein the tail hemispherical head is also provided with a rear-convex transmission guide rod, and an outer die head is provided outside the tail hemispherical head; the center of the transmission guide rod is a through hole, which passes through the radial center of the tail hemispherical head and the forward-convex guide structure from back to front; one end of the fixed base is fixedly connected to the transmission guide rod; a linear elastic component is sleeved inside the transmission guide rod; an inner die head, which includes a forward-convex guide protrusion and a rear end mounting seat; an eccentric adjustment ring, which includes a ring body; and multiple sets of diameters for adjusting the ring body for micro-adjustment. The multiple sets of radial micro-adjustment rods are fixedly connected at both ends to the ring body and one end of the motor of the multiple sets of radial micro-adjustment rods of the ring body, which is used to coordinate the circular motion of the multiple sets of radial micro-adjustment rods. The other end is electrically connected to the concentricity control module, which is used to accurately correct the plastic particles and / or meet the control of the concentricity deviation of the extrusion shape on the cable. This utility model ensures that the machine is always running when producing different batches of cables, regardless of the shape of the battery cell, the softened plastic extrusion, and the amount of extruded plastic, thus meeting the product's concentricity technical requirements and improving cable production efficiency. Furthermore, during production, the concentricity control module is always precisely adjusted according to the cable concentricity technical standard to ensure that the concentricity index of different batches of cables meets the design standard, thus ensuring product quality.

[0004] However, the existing manual eccentric adjustment mechanism cannot effectively adjust the internal diameter of the extrusion mold, and its diameter cannot be flexibly adjusted according to the needs of different insulation layer thicknesses, which has certain limitations. Furthermore, the adjustment block will be damaged after long-term use, and its disassembly and assembly structure is relatively complex, making it difficult to disassemble and replace quickly and conveniently, which is time-consuming and laborious and reduces subsequent work efficiency. Utility Model Content

[0005] To overcome the problems of existing adjustment mechanisms being unable to adjust the thickness of the extruded insulation layer, lacking flexibility, and having adjustment blocks that are damaged after prolonged use and whose replacement process is complicated, thus affecting subsequent work efficiency.

[0006] The technical solution of this utility model is as follows: a manual eccentric adjustment mechanism for an insulating layer extrusion mold, including an outer shell and an extrusion mold body. The outer shell has a movable groove inside. Four L-shaped support plates are fixedly connected to the four ends of the outer shell. Double-ended screws are meshed and connected through the four L-shaped support plates. One end of the double-ended screw is connected to an adjustment block located inside the movable groove. A connecting block is provided between the adjustment block and the double-ended screw. A positioning groove is provided inside the connecting block. Limit grooves are provided on both the left and right sides of the positioning groove. A connecting rod is connected through the limiting groove. A plug is fixedly connected to one side of the connecting rod. A spring is sleeved on the outside of the connecting rod. A positioning block that is inserted into the positioning groove is fixedly connected to the upper end face of the adjustment block. Slots are provided on both the left and right sides of the positioning block.

[0007] Preferably, by fixing the positioning block into the positioning groove, the pulling connecting rod is released, allowing it to pop out under the relaxation of the spring, so that the insert on one side of the connecting rod is inserted into the slot to strengthen the fixing of the adjusting block. This structure facilitates disassembly and assembly, making it faster and more convenient to replace the adjusting block, saving time and effort, and thus improving subsequent work efficiency.

[0008] Preferably, the front end face of the outer casing has an extrusion port, and an auxiliary block is fixedly connected to the upper end face of the double-ended screw. An anti-slip strip is fixedly connected to the surface of the auxiliary block.

[0009] Preferably, the front end face of the extrusion mold body is fixedly connected to an extrusion head located inside the outer shell, and the four end faces of the rear end face of the outer shell body are all fixedly connected to reinforcing blocks.

[0010] Preferably, a sealing gasket is fixedly connected to the outside of the extruder head, and a sealing groove is opened inside the outer shell, into which the sealing gasket is inserted.

[0011] Preferably, each of the four reinforcing blocks has a reinforcing groove inside, and the outer corner of the extrusion head is inserted into the four reinforcing grooves.

[0012] Preferably, guide rods are fixedly connected to both the upper and lower ends inside the limiting groove, and a through hole is opened on one side of the limiting groove, through which the connecting rod and the connecting block pass.

[0013] Preferably, guide blocks that are slidably sleeved on the outside of the two guide rods are fixedly connected to both the upper and lower ends of the insert.

[0014] Preferably, the positioning block is inserted into the positioning groove, and the insert block is inserted into the slot.

[0015] The beneficial effects of this utility model are:

[0016] 1. The manual eccentric adjustment mechanism of this insulation layer extrusion mold, through the rotational meshing of the double-headed screw, drives the adjustment block at one end to move up and down, so that it moves in the movable groove and slowly approaches the thickness adjustment point inside the mold, so that the required extrusion thickness can be flexibly adjusted, making it more flexible.

[0017] 2. The manual eccentric adjustment mechanism of this insulation layer extrusion mold allows for easy disassembly. During disassembly, pulling the two connecting rods simultaneously disengages the insert block from the slot and pulls it out to one end, disengaging the positioning block from the positioning groove. During installation, the positioning block is secured in the positioning groove, and releasing the pulled connecting rod allows it to spring out, enabling the insert block on one side of the connecting rod to be inserted into the slot for enhanced installation and fixation. This convenient disassembly and assembly structure allows for faster and more convenient replacement of the adjustment block, saving time and effort and improving subsequent work efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This utility model provides an embodiment: a manual eccentric adjustment mechanism for an insulating layer extrusion mold, including an outer shell 1 and an extrusion mold body 5. The outer shell 1 has an internal movable groove 11. Four L-shaped support plates 3 are fixedly connected to the four external ends of the outer shell 1. Double-ended screws 4 are meshed and penetrated through the interiors of the four L-shaped support plates 3. One end of the double-ended screw 4 is connected to an adjusting block 9 located inside the movable groove 11. A connecting block 10 is provided between the adjusting block 9 and the double-ended screw 4. A positioning groove 12 is provided inside the connecting block 10. Limiting grooves 15 are provided on both the left and right sides of the positioning groove 12. A connecting rod 20 is penetrated through the limiting groove 15. An insert block 14 is fixedly connected to one side of the connecting rod 20. A spring 17 is sleeved on the outside of the connecting rod 20. A positioning block 13, which is inserted into the positioning groove 12, is fixedly connected to the upper end face of the adjusting block 9. Slots 16 are provided on both the left and right sides of the positioning block 13. Figure 2 As shown, it includes an extrusion mold body 5. In this application, the structure of the extrusion mold body 5 is a prior art solution. The applicant will not provide a detailed description of the internal structure and components or their connection relationships of the extrusion mold body 5. Therefore, the above-mentioned structure and connection relationships are all prior art. The applicant has not made any improvements to the components inside the extrusion mold body 5.

[0026] Please see Figures 1-3 In this embodiment, the front end face of the outer shell 1 is provided with an extrusion port 2, the upper end face of the double-headed screw 4 is fixedly connected with an auxiliary block, and the surface of the auxiliary block is fixedly connected with an anti-slip strip. The front end face of the extrusion mold body 5 is fixedly connected with an extrusion head 6 located inside the outer shell 1. The four end faces of the rear end face of the outer shell 1 are all fixedly connected with reinforcing blocks 7. The outside of the extrusion head 6 is fixedly connected with a sealing gasket 8. The inside of the outer shell 1 is provided with a sealing groove, and the sealing gasket 8 is inserted into the sealing groove. The inside of each of the four reinforcing blocks 7 is provided with a reinforcing groove, and the outer corner of the extrusion head 6 is inserted into the four reinforcing grooves. By rotating... Rotating the double-headed screw 4 at four angles causes it to engage internally and move up and down, which in turn moves the connected adjusting block 9, allowing the adjusting block 9 to flexibly adjust the thickness of the insulation layer. By pulling the two connecting rods 20, the insert 14 on one side is disengaged from the slot 16. At the same time, the spring 17 sleeved on the outside of the connecting rod 20 is compressed. After the insert 14 is disengaged from the slot 16, the adjusting block 9 is pulled to one end by a pulling force, so that the positioning block 13 at the upper end of the adjusting block 9 is disengaged from the positioning groove 12, thus completing the disassembly of the adjusting block 9.

[0027] Please see Figures 4-5In this embodiment, guide rods 18 are fixedly connected to both the upper and lower ends of the limiting groove 15. A through hole is provided on one side of the limiting groove 15. The connecting rod 20 and the connecting block 10 pass through the through hole. Guide blocks 19 that are slidably sleeved on the outside of the two guide rods 18 are fixedly connected to both the upper and lower ends of the insert block 14. The positioning block 13 is inserted into the positioning groove 12, and the insert block 14 is inserted into the slot 16. During installation, the positioning block 13 at one end of the adjusting block 9 is first inserted into the positioning groove 12 for fixation. After fixation is completed, the pulling connecting rod 20 is released, so that the connecting rod 20 pops out under the relaxation of the spring 17, which also drives the insert block 14 to pop out, so that the insert block 14 is inserted into the slot 16 inside the positioning block 13 for fixation. The installation of the adjusting block 9 can then be completed.

[0028] During operation, rotating the four-angled double-headed screw 4 causes it to engage internally and move up and down, simultaneously displacing the connected adjusting block 9. This allows the adjusting block 9 to flexibly adjust the thickness of the insulation layer. Pulling the two connecting rods 20 causes one side of the insert 14 to disengage from the slot 16. Simultaneously, the spring 17 sleeved on the outside of the connecting rod 20 is compressed. After the insert 14 disengages from the slot 16, the adjusting block 9 is pulled to one end, causing the positioning block 13 at the upper end of the adjusting block 9 to disengage from the positioning groove 12, thus completing the disassembly of the adjusting block 9. During installation, first, the positioning block 13 at one end of the adjusting block 9 is inserted into the positioning groove 12 for fixation. After fixation, the pulling connecting rod 20 is released, causing the connecting rod 20 to pop out under the relaxation of the spring 17, simultaneously causing the insert 14 to pop out and insert into the slot 16 inside the positioning block 13 for fixation, thus completing the installation of the adjusting block 9.

[0029] Through the above steps, the rotating engagement of the double-headed screw 4 drives the adjusting block 9 at one end to move up and down, allowing it to move within the movable groove 11 and slowly approach the thickness adjustment point inside the mold. This allows for flexible adjustment of the required extrusion thickness, making it more flexible and solving the problems of existing adjustment mechanisms being unable to adjust the thickness of the insulation layer extrusion, lacking flexibility, and causing the adjusting block 9 to wear out after prolonged use, with a complicated replacement process that affects subsequent work efficiency.
