Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lead extruders, and in particular relates to a disassembly device for a mold core and a mold core seat. Background Art
[0002] Lead extruder, as a kind of equipment specially used for manufacturing wires and cables, has the ability to evenly wrap the lead liquid on the cable to form a protective lead sheath. This lead sheath is widely used in mines, cross-river cables, cross-sea cables and other occasions that require special protection.
[0003] The lead extruder usually includes a die base, a die core, a die core base, a die cover, a hydraulic die adjustment device, and a water spray ring. These components work together to ensure that the lead liquid can be evenly and continuously coated on the cable to form a smooth and dense lead sheath. Among them, the die core is a key component that determines the specifications of the cable. When it is necessary to produce cables of different specifications, it is necessary to replace the die core of different specifications. In existing lead extruders, die cores of different specifications are usually used in conjunction with die core bases of corresponding specifications, such as Figure 1 As shown, there are multiple core seats, each of which is embedded and connected in sequence, and the inner diameter of each core seat is adapted to the outer diameter of cores of different specifications. The existing core 1 is fixed on the core seat 201 with the smallest inner diameter. When the core that is adapted to the core seat 202 needs to be replaced, it is only necessary to first disassemble the existing core 1 and the core seat 201, and then embed the core to be replaced in the adapted core seat 202.
[0004] Since the core and the core seat, and the core seat and the core seat are tightly embedded, manual disassembly is currently commonly used. However, if the demolding time is not properly arranged, the lead liquid residue will cool and solidify on the core and the core seat. In addition, the high temperature environment of the core and the core seat after the lead extruder is continuously operated makes manual disassembly much more difficult. Therefore, in the prior art, operators usually use heating equipment such as hot air guns or electric heat guns to evenly heat the cooled and solidified lead liquid residue between the core and the core seat, and between the core seat and the core seat to soften it. Subsequently, the operator will use manual knocking to release the tightly embedded connection between the core and the core seat, and between the core seat and the core seat, thereby achieving disassembly.
[0005] However, the existing manual disassembly method not only increases labor intensity and reduces production efficiency, but also easily causes mold core wear through manual knocking, causing core eccentricity, directly affecting the position accuracy of the mold core, and further affecting product quality. Therefore, it is necessary to design a new type of mold core and core seat disassembly device to reduce labor intensity, improve disassembly efficiency, ensure mold core position accuracy, and improve product quality. Utility Model Content
[0006] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art, and to provide a core and core seat disassembly device. The utility model adopts a limit step hole design adapted to the core and the core seat, and a hydraulic drive mechanism cooperates with a push rod, which can realize the disassembly of the core and the core seat, and effectively solves the problem of low production efficiency and damage to the core caused by manual disassembly of the core. The utility model not only improves the disassembly efficiency and reduces the labor intensity, but also ensures the core position accuracy, which is conducive to improving product quality.
[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0008] The utility model discloses a core and core seat disassembly device, comprising a hydraulic drive mechanism, a support seat, a disassembly seat and a push rod, wherein the disassembly seat is fixed on the support seat, and a plurality of limit step holes respectively matched with core seats of different specifications are provided on the disassembly seat, the hydraulic drive mechanism is fixed on the top of the disassembly seat through the support seat, the push rod is located between the hydraulic drive mechanism and the disassembly seat, and the hydraulic drive mechanism cooperates with the push rod to disassemble the core and the core seat.
[0009] The disassembly seat includes an intermediate pad, a first limiting sleeve and a second limiting sleeve. The intermediate pad is fixed on the support seat. The first limiting sleeve and the second limiting sleeve are movably stacked on the intermediate pad in sequence. The limiting step holes are respectively opened on the intermediate pad, the first limiting sleeve and the second limiting sleeve, and the limiting step holes on the intermediate pad, the first limiting sleeve and the second limiting sleeve are coaxially arranged.
[0010] The support seat includes a base plate, a cover plate and a support rod. The cover plate and the base plate are respectively fixed to the upper and lower ends of the support rod. The disassembly seat is fixed to the middle of the support rod. The hydraulic drive mechanism is fixed to the cover plate to control the movement of the push rod.
[0011] The hydraulic drive mechanism includes a manual oil pump, an oil cylinder and a fixed plate. The manual oil pump and the oil cylinder are respectively fixed on both sides of the fixed plate, and one end of the oil cylinder is fixed at the middle position of the cover plate and connected to the push rod, and the other end is connected to the manual oil pump through a high-pressure hose.
[0012] There are at least three support rods, which are fixed on the bottom plate at equal intervals and distributed in a ring shape.
[0013] The advantages of adopting the utility model are:
[0014] 1. The utility model realizes the rapid and accurate disassembly of the mold core and the mold core seat through the design of the hydraulic drive mechanism and the ejector rod. Compared with the traditional knocking disassembly method relying on manpower, it significantly reduces the labor intensity of the operator and greatly improves the production efficiency;
[0015] At the same time, this coordination method solves the difficulties in controlling the disassembly force and position, ensures uniform and stable disassembly force, and effectively avoids the core eccentricity problem caused by damage to the core and core seat caused by manual knocking. It not only protects the position accuracy of the core, but also further guarantees the final quality of the product.
[0016] In addition, the utility model not only solves the problems of low production efficiency and damage to the mold core caused by manual disassembly of the mold core, but also improves the versatility and adaptability of the device by adopting a limiting step hole design that adapts to the mold core and the core seat, so that it can adapt to the disassembly of mold cores and core seats of different sizes and specifications.
[0017] 2. The utility model uses a movable stacking design to place limit sleeves of different specifications on the middle pad in sequence, so that the device can flexibly adapt to mold cores and mold core seats of different specifications and quantities, simplifying the disassembly and replacement operations and improving the structural adaptability and flexibility of the device.
[0018] 3. The utility model improves the stability of the device by fixedly connecting the support rod with the bottom plate, the disassembly seat and the cover plate.
[0019] 4. The utility model controls the oil cylinder to exert force on the ejector rod through a manual oil pump, thereby realizing efficient disassembly of the mold core and the mold core seat, and at the same time, improving the stability and safety during the operation.
[0020] 5.

DETAILED DESCRIPTION
[0026] The following will be described in detail in conjunction with the drawings and specific implementation methods of the specification. In the present utility model, for the convenience of description, the description of the relative position relationship of each component is described according to the layout of the drawings in the specification, such as: the position relationship of front, back, top, bottom, left, right, etc. is determined according to the layout direction of the drawings in the specification.
[0027] The core and core seat disassembly device of the utility model refers to a device capable of disassembling the core and the core seat. Figure 1-4 As shown, it includes a hydraulic drive mechanism, a support seat 3, a disassembly seat and a push rod 4. The disassembly seat is fixed on the support seat 3, and a plurality of limit step holes are provided on the disassembly seat, which are respectively adapted to core seats of different specifications. The limit step holes are used to place the core and core seat fixed as a whole and ready to be disassembled. The hydraulic drive mechanism is fixed above the disassembly seat through the support seat 3, and the push rod 4 is located between the hydraulic drive mechanism and the disassembly seat. The hydraulic drive mechanism and the push rod 4 cooperate to disassemble the core and the core seat. Specifically, as Figure 1-2 As shown, the hydraulic drive mechanism is controlled to drive the push rod 4 to move downward, so that the lower end of the push rod 4 abuts against the core to be disassembled and the core seat. Then, the hydraulic drive mechanism applies a force to the core and the core seat through the push rod 4. After the push rod 4 passes through the disassembly seat, the core to be disassembled and the core seat are smoothly ejected, thereby completing the disassembly of the core and the core seat.
[0028] like Figure 1-2 As shown, the push rod 4 and the hydraulic drive mechanism can be either a split structure or a fixed connection structure. Figure 2 Taking the direction shown as an example, the core and the core seat are first placed in the limiting step hole of the disassembly seat. Since the push rod 4 and the hydraulic drive mechanism are split structures, the push rod 4 can be placed between the core and the hydraulic drive mechanism according to the actual situation, and the upper end of the push rod 4 is abutted against the piston rod of the hydraulic drive mechanism, and then the piston rod of the hydraulic drive mechanism controls the push rod 4 to apply a force downward to the core and the core seat to be disassembled, so that the core and the core seat can be disassembled. When the fixed connection structure is used for disassembly, the difference from the split structure disassembly is that the upper end of the push rod 4 is fixedly connected to the piston rod of the hydraulic drive mechanism. At this time, the hydraulic drive mechanism can be controlled to make the push rod 4 move upward to avoid the position, providing a placement space for the core and the core seat to be disassembled. Subsequently, the core and the core seat to be disassembled are placed in the limiting step hole of the disassembly seat, and then the piston rod of the hydraulic drive mechanism controls the push rod 4 to move downward to apply a force to the core and the core seat to be disassembled, so that the core and the core seat can be disassembled. The utility model adopts a limit step hole design that is adapted to the mold core and the mold core seat, and the cooperation of the hydraulic drive mechanism and the ejector rod, which not only improves the disassembly efficiency and reduces the labor intensity, but also ensures the mold core position accuracy, which is beneficial to improving product quality.
[0029] It should be noted that the lower end of the push rod 4 abuts against the core to be removed and the core seat, that is, it abuts against the appropriate position of the inner wall of the truncated cone hole of the core to be removed and the core seat, or abuts against the top of the core to be removed and the core seat. Since the embedded connection relationship between the core and the core seat, and the shape and structure of the core and the core seat are all in the prior art, they are not described here. The diameter of the lower end of the push rod 4 must be compatible with the abutment between the core to be removed and the core seat. Therefore, push rods 4 of different diameters can be configured, or plugs of different diameters can be configured at the lower end of the push rod 4.
[0030] like Figure 2-4 As shown, in order to adapt to different specifications of the core and the core seat for disassembly, the disassembly seat includes an intermediate pad 5, a first limiting sleeve 701 and a second limiting sleeve 702, and a limiting step hole is respectively provided, and the limiting step holes on the intermediate pad 5, the first limiting sleeve 701 and the second limiting sleeve 702 are coaxially arranged to ensure that the ejector rod 4 moves linearly downward along the same axis when participating in the disassembly work, avoiding the displacement and bending of the ejector rod 4, which is conducive to the smooth disassembly of the core and the core seat. When entering the disassembly procedure, the first limiting sleeve 701 and the second limiting sleeve 702 are movably stacked on the top of the intermediate pad 5 in sequence.
[0031] Disassemble by using the top rod 4 of the fixed connection structure Figure 1 As an example, the core 1, core seat 201 and core seat 202 shown in the figure are used as examples. The working principle of the present utility model is as follows:
[0032] 1. First, the operator stacks the first limiting sleeve 701 and the second limiting sleeve 702 on top of the middle pad 5 in sequence, and ensures that the limiting step holes are coaxially arranged. Then, by controlling the hydraulic drive mechanism, the push rod 4 moves upward to avoid the position, providing a placement space for the core and core seat to be disassembled. Next, place the core and core seat to be disassembled into the limiting step hole of the disassembly seat, and ensure that the limiting step hole is compatible with the core seats of different specifications to be disassembled. At the same time, it is also necessary to ensure that the lower end of the push rod 4 is compatible with the abutment position of the core and core seat to be disassembled, and complete the preparation work before disassembly.
[0033] 2. When the core 1 needs to be removed, the operator places the embedded core and the core seat on the second limiting sleeve 702, and ensures that the limiting step hole of the second limiting sleeve 702 corresponds to the first core seat 201, so as to provide support for the embedded core and the core seat. The hydraulic drive mechanism cooperates with the push rod 4 to make the lower end of the push rod 4 abut against the inner wall of the truncated cone hole of the core 1 to be removed. Subsequently, the hydraulic drive mechanism applies a downward force to the core 1 to be removed through the push rod 4. After passing through the limiting step hole of the middle pad 5, the core 1 to be removed is ejected from the first core seat 201, thereby completing the removal of the core 1. At this time, the embedded core seat stays on the second limiting sleeve 702.
[0034] 3. When the first core seat 201 needs to be removed, the operator first moves the second limiting sleeve 702 together with the embedded core seat, while the intermediate pad 5 and the first limiting sleeve 701 are kept stacked on the removal seat, and then the embedded core seat is placed on the first limiting sleeve 701, and the limiting step hole of the first limiting sleeve 701 is aligned with the second core seat 202 to provide support for the embedded core seat. The hydraulic drive mechanism cooperates with the push rod 4 to make the lower end of the push rod 4 abut against the inner wall of the truncated cone hole of the first core seat 201 to be removed. Subsequently, the hydraulic drive mechanism applies a downward force to the first core seat 201 through the push rod 4. The first core seat 201 to be disassembled is ejected from the second core seat 202 after passing through the limiting step hole of the middle pad 5, thereby completing the disassembly of the first core seat 201. At this time, the embedded and connected second core seat 202 and the third core seat 203 stay on the first limiting sleeve 701.
[0035] 4. When the second core seat 202 needs to be removed, the operator first moves the first limiting sleeve 701 together with the embedded second core seat 202 and the third core seat 203, and the disassembly seat only has the middle pad 5, and then places the embedded second core seat 202 and the third core seat 203 on the middle pad 5, and ensures that the limiting step hole of the middle pad 5 corresponds to the third core seat 203, providing support for the embedded second core seat 202 and the third core seat 203. The hydraulic drive mechanism cooperates with the push rod 4 to make the lower end of the push rod 4 abut against the inner wall of the truncated cone hole of the second core seat 202 to be disassembled. Subsequently, the hydraulic drive mechanism applies a downward force to the second core seat 202 through the push rod 4, and the second core seat 202 to be disassembled is ejected from the third core seat 203 after passing through the limiting step hole of the middle pad 5, thereby completing the disassembly of the second core seat 202.
[0036] The movable stacking design of the middle pad and the limiting sleeves of different specifications improves the structural adaptability and flexibility of the utility model, and facilitates the rapid disassembly and replacement of mold cores and mold core seats of different specifications.
[0037] like Figure 2-4 As shown, the support seat 3 includes a bottom plate 8, a cover plate 9 and a support rod 10. The cover plate 9 and the bottom plate 8 are respectively fixed to the upper and lower ends of the support rod 10, the disassembly seat is fixed to the middle of the support rod 10, and the hydraulic drive mechanism is fixed to the cover plate 9 to control the movement of the ejector rod 4. By fixedly connecting the support rod 10 with the bottom plate 8, the disassembly seat and the cover plate 9, the stability of the core and the core seat disassembly device is improved.
[0038] like Figure 3-4As shown, the hydraulic drive mechanism includes a manual oil pump 11, an oil cylinder 12 and a fixed plate 13, and the manual oil pump 11 and the oil cylinder 12 are fixed on both sides of the fixed plate 13 respectively. One end of the oil cylinder 12 is also fixed in the middle of the cover plate 9, and the piston rod of the oil cylinder 12 passes through the cover plate 9 and abuts against the upper end of the push rod 4, and the other end is connected to the manual oil pump 11 through the high-pressure hose 6. Through the control of the manual oil pump 11, the piston rod of the oil cylinder 12 applies a force to the upper end of the push rod 4, thereby prompting the lower end of the push rod 4 to push out the core and the core seat to be disassembled, which not only realizes the efficient disassembly of the core and the core seat, but also significantly improves the stability and safety during the operation.
[0039] like Figure 2-4 As shown, there are at least three support rods 10, which are fixed on the bottom plate 8 at equal intervals and distributed in a ring shape, further enhancing the structural stability of the disassembly device when disassembling the mold core and the mold core seat.

Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes; all disclosed features, or all methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any way.
