Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glue injection molds, and particularly relates to a reinforced cable extrusion mold structure for hoisting equipment. BACKGROUND

[0002] The cable of hoisting equipment needs to bear frequent bending and stretching, and is usually made of a parallel co-extrusion mold. On one side, the cable is wrapped with insulating material, and on the other side, the conductor core is wrapped with insulating material. The two are connected together through the insulating material to form an “8” shape.

[0003] The co-extrusion mold comprises a mold core and a mold cover. The mold core guides the cable core to pass through the wire passing port. The discharge port of the mold cover is no longer circular, but is designed into an “8” shape or similar double-hole structure. The shape of the hole directly determines the distribution and interface shape of the two materials on the final product.

[0004] There is an extrusion gap between the wire passing port and the discharge port. The insulating material is extruded from the gap to wrap the steel wire rope and the conductor core, thereby forming the cable. However, the extrusion gap of the mold cannot be adjusted, so that the thickness of the insulating material wrapped around the outer periphery of the steel wire rope and the conductor core is a fixed value, and the wrapped thickness of the insulating material cannot be adjusted according to production requirements, thereby having the defect of low mold applicability.

[0048] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0049] Please refer to the following: Figures 1 to 7 The present invention describes the structure of a reinforced cable extrusion mold for lifting equipment. The reinforced cable extrusion mold structure for lifting equipment includes a core unit 10, a sleeve unit 20, and two adjustment units 30. The core unit 10 includes two core seats 101 and a connecting structure disposed between the two core seats 101. The connecting structure extends and retracts along a first direction and is used to adjust the distance between the two core seats 101. The sleeve unit 20 includes a cover 201, which has a receiving cavity 2011 for accommodating the end of the core unit 10. The cover 201 also has an adjustment groove 2012 corresponding to each core seat 101 and a connecting groove 30. The through groove 2013 between 012 and the adjusting groove 2012 allows the discharge end of the core seat 101 to extend into it; the adjusting unit 30 is correspondingly arranged in the adjusting groove 2012. The adjusting unit 30 includes a turntable 301 arranged in the adjusting groove 2012, a plurality of outer arc plates 302 spaced apart on the outer periphery of the turntable 301, and a drive structure connected to the turntable 301. The outer arc plates 302 have openings that mate with the through groove 2013. The inner diameters of the outer arc plates 302 are different. The drive structure is used to adjust the position of the outer arc plates 302 so that different outer arc plates 302 mate with the through groove 2013.

[0050] It should be noted that a cover plate 2018 is embedded at the port of the adjustment groove 2012. The cover plate 2018 has a notch 20181 that is adapted to the outer arc plate 302. After replacing the outer arc plate 302 with a different inner diameter, the staff can adapt it by replacing the cover plate 2018 with a different size notch 20181.

[0051] The reinforced cable extrusion mold structure for lifting equipment provided in this embodiment, compared with the prior art, uses a drive structure to rotate the turntable 301, moving the outer arc plate 302 of the required inner diameter to the position where it aligns with the through groove 2013. The extrusion gap is formed by the annular space between the outer wall of the core seat 101's discharge end and the inner wall of the selected outer arc plate 302. Changes in the inner diameter of the outer arc plate 302 cause changes in its center. By adjusting the relative position of the core seat 101 and the center of the outer arc plate 302 through the connecting structure, the central axis of the core seat 101 always coincides with the center of the outer arc plate 302, regardless of changes in the center of the outer arc plate 302. This invention changes the size of the extrusion gap by replacing the outer arc plate 302 with different inner diameters, thereby extruding insulation layers of different thicknesses and improving the mold's applicability.

[0052] In some embodiments, see Figure 2 and Figure 3 The driving structure includes a movable seat 303, a transverse component 304, and a rotating component 305. The movable seat 303 is located in the adjustment groove 2012 and is slidably connected to the cover 201 along the first direction. The turntable 301 is rotatably connected to the movable seat 303, and the rotation axis of the turntable 301 is perpendicular to the seat surface of the movable seat 303. The transverse component 304 is drivenly connected to the movable seat 303 and is used to drive the movable seat 303 to slide. The transverse component 304 is a linear slide rail or a linear module. The rotating component 305 is drivenly connected to the turntable 301 and is used to drive the turntable 301 to rotate. The rotating component 305 is a servo motor.

[0053] The rotating component 305 starts and drives the turntable 301 to rotate. During the rotation of the turntable 301, the outer arc plates 302 with different inner diameters are aligned with the through groove 2013. Then, the position of the moving seat 303 is moved as a whole by the transverse component 304 so that the outer arc plates 302 with different inner diameters can be connected with the through groove 2013.

[0054] In some embodiments, see Figure 3 The seat surface of the movable seat 303 is provided with positioning grooves 3031 that correspond one-to-one with the outer arc plate 302. Positioning units 40 are provided in the positioning grooves 3031. The turntable 301 is provided with slots 3011 that are aligned one-to-one with the positioning grooves 3031.

[0055] The positioning unit 40 includes a positioning roller 401 and a first elastic member 402. The positioning roller 401 is disposed in the positioning groove 3031 and is slidably connected to the movable seat 303. The moving direction of the positioning roller 401 is parallel to the rotation axis of the turntable 301. One end of the positioning roller 401 near the turntable 301 is cylindrical. The positioning roller 401 is inserted into and adapted to the slot 3011. The first elastic member 402 is fixed between the positioning roller 401 and the movable seat 303 and has a pre-tightening force that causes the positioning roller 401 to extend out of the positioning groove 3031. The first elastic member 402 is a spring or a spring rod.

[0056] When the turntable 301 rotates, it will squeeze and overcome the elastic force of the first elastic element 402, pressing the positioning roller 401 back into the positioning groove 3031; when the slot 3011 on the turntable 301 rotates to the position aligned with the positioning groove 3031, the preload of the first elastic element 402 will instantly push the positioning roller 401 out, so that it is inserted into the slot 3011, thereby achieving mechanical positioning.

[0057] When the turntable 301 rotates to the working position of the specific outer arc plate 302, the positioning roller 401 inserts into the corresponding slot 3011 on the turntable 301 under the action of elasticity, producing a clear "click" feeling, providing the operator with clear gear feedback, making the adjustment process faster and more accurate.

[0058] In some embodiments, see Figure 5 The connecting structure includes a connecting column 102, two side top strips 103, and two side top members 104. The connecting column 102 is connected to the inner wall of the cover 201, and the connecting column 102 has a sliding groove 1021 on both sides along the first direction. The side top strips 103 are correspondingly arranged in the sliding grooves 1021, and the side top strips 103 are slidably connected to the connecting column 102 along the first direction. The side of the side top strip 103 away from the connecting column 102 is fixedly connected to the corresponding core seat 101. The side top members 104 are correspondingly arranged in the sliding grooves 1021, and the side top members 104 are fixedly connected between the side top strips 103 and the connecting column 102. The side top members 104 extend and retract along the first direction, and the side top members 104 are telescopic cylinders or hydraulic cylinders.

[0059] The connecting column 102 serves as a stable foundation, and the side top strips 103 on both sides slide within the slide groove 1021, ensuring that the two core seats 101 always move in parallel and avoiding skew during adjustment. The two side top parts 104 can be controlled independently, which means that not only can the distance between the two core seats 101 be adjusted synchronously, but also asymmetrical adjustment can be performed to adapt to asymmetrical cable structures, further improving the applicability of the mold.

[0060] In some embodiments, see Figure 6Connecting strips 50 are fixedly connected to both sides of the connecting column 102 along the second direction. The inner wall of the cover 201 is provided with a connecting groove 2014 that is compatible with the connecting strips 50. The inner wall of the connecting groove 2014 is provided with a slot 2015 that communicates with the outside.

[0061] A storage groove 501 is provided on the end face of the connecting strip 50 away from the gap adjustment unit 30. A snap-fit ​​post 502 is slidably provided in the storage groove 501. The snap-fit ​​post 502 moves along the extension direction of the connecting strip 50. The snap-fit ​​post 502 is inserted into the slot 2015. A second elastic member 503 is provided in the storage groove 501. The second elastic member 503 has a pre-tightening force that causes the snap-fit ​​post 502 to extend into the slot 2015. The second elastic member 503 is a spring or a spring rod.

[0062] During installation, the connecting strip 50 is inserted into the connecting groove 2014 of the cover 201. When inserted into place, the locking post 502 automatically pops out under the elastic force of the second elastic member 503 and locks into the slot 2015, thus achieving a locking effect. During disassembly, simply press the locking post 502 from the outside to retract it into the receiving groove 501, and the entire mold core unit 10 can be pulled out from the cover 201.

[0063] The snap-fit ​​post 502 enables quick connection and separation between the core unit 10 and the sleeve unit 20, and locking can be completed without tools, which greatly facilitates maintenance operations such as cleaning the mold and replacing worn parts, and improves production efficiency; the second elastic element 503 provides continuous locking force to ensure that the core unit 10 will not loosen during the extrusion process.

[0064] In some embodiments, see Figure 6 A limiting groove 504 is provided on the outer wall of the connecting strip 50. A reinforcing groove 2016 corresponding to the limiting groove 504 is provided on the inner wall of the connecting groove 2014. A limiting block 505 is provided in the limiting groove 504. The limiting block 505 is slidably connected to the connecting strip 50. The moving direction of the limiting block 505 is perpendicular to the extending direction of the connecting strip 50. A third elastic member 506 is fixedly connected between the limiting block 505 and the connecting strip 50. The third elastic member 506 has a pre-tightening force that causes the limiting block 505 to insert into the reinforcing groove 2016. The third elastic member 506 is a spring or a spring rod.

[0065] The connecting bar 50 is equipped with a transmission unit 60, which is used to push the limiting block 505 into the reinforcing groove 2016.

[0066] Specifically, the connecting strip 50 has a rotating groove 507 that connects the receiving groove 501 and the limiting groove 504; the transmission unit 60 includes a rotating roller 601 and a transmission sleeve 602; the rotating roller 601 is located in the rotating groove 507 and is rotatably connected to the connecting strip 50. The rotation axis of the rotating roller 601 is parallel to the extension direction of the connecting strip 50. The locking post 502 is slidably connected to the rotating roller 601, and the second elastic member 503 is fixed between the locking post 502 and the rotating roller 601; the transmission sleeve 602 is located in the limiting groove 504 and is sleeved on the outer periphery of the rotating roller 601. The transmission sleeve 602 is screwed to the inner wall of the transmission sleeve 602 and is also slidably connected to the rotating roller 601. The transmission sleeve 602 moves along the axial direction of the rotating roller 601 and abuts against the limiting block 505.

[0067] After the connecting strip 50 is embedded in the connecting groove 2014, the snap-fit ​​post 502 extends out through the snap-fit ​​groove 2015 to the outside. Then, the operator rotates the snap-fit ​​post 502, which drives the transmission sleeve 602 to rotate. As a result, the transmission sleeve 602 presses the limiting block 505, causing the limiting block 505 to extend out of the limiting groove 504 and into the reinforcing groove 2016. This enhances the connection strength between the connecting strip 50 and the cover 201, thereby improving the stability of the core seat 101.

[0068] When the core seat 101 needs to be removed, the operator rotates the locking post 502 in the opposite direction, causing the locking post 502 to drive the transmission sleeve 602 to move away from the limiting block 505. At this time, the second elastic element 503 releases its elastic force, causing the limiting block 505 to retract from the reinforcing groove 2016 back into the limiting groove 504. Then, the operator can press the locking post 502 to remove the connecting strip 50 from the connecting groove 2014.

[0069] In some embodiments, see Figure 6 An adsorption plate 5051 is fixedly attached to the side of the limiting block 505 facing the reinforcing groove 2016.

[0070] When the limiting block 505 is pushed into the reinforcing groove 2016, the soft adsorption plate 5051 first undergoes elastic deformation, squeezing out the air inside and forming a local vacuum with the wall of the reinforcing groove 2016, generating adsorption force. Utilizing the negative adsorption effect of the adsorption plate 5051, an additional adhesion force can be provided, making the locking more secure and further preventing micro-movement.

[0071] In some embodiments, see Figure 2 and Figure 7 The outer arc plate 302 has sealing plates 3021 fixedly connected to both sides of the opening, and the through groove 2013 has sealing grooves 2017 on both sides that are compatible with the sealing plates 3021.

[0072] The sealing plates 3021 on the currently working outer arc plate 302 are tightly inserted into the sealing grooves 2017 on both sides of the through groove 2013, forming a mechanical sealing barrier.

[0073] Based on the same inventive concept, this application also provides a cable made using the above-mentioned lifting equipment reinforced cable extrusion mold structure.
