Description

Technical Field

[0001] This invention belongs to the field of hardware recycling technology, and in particular relates to a device and recycling method for recycling hardware parts of injection molded products. Background Technology

[0002] Currently, in-mold insert injection molded products, hardware accounts for more than 70% of the product material cost. To save manufacturing costs, hardware recycling is of great significance for reducing product costs.

[0003] Currently, the recycling of injection-molded hardware parts with embedded plastic bases at the bolt ends typically involves high-temperature heating to soften the plastic bases, making it easier for the plastic to separate from the bolt. This is followed by manual removal, which is time-consuming, labor-intensive, and inefficient. To address these issues, we provide equipment and a recycling method for in-mold injection-molded hardware parts, resolving the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for recycling metal parts in injection molded products. A rectangular heating tube moves downwards to soften the injection molded metal parts. Then, as the rectangular heating tube moves upwards, a limiting component moves the clamping plate closer to the outer wall of the bolt, thus securing the bolt. An arc-shaped limiting plate abuts against the top of the plastic base. As the clamping plate continues to move upwards, the bolt separates from the plastic base, thereby achieving the recycling of the metal parts. This effectively improves the recycling efficiency and ease of use of the metal parts. It solves the problem of existing methods for recycling injection molded metal parts with embedded plastic bases at the bolt ends, which typically involve high-temperature heating to soften the plastic base, making it easier to separate the plastic from the bolt, followed by manual removal—a time-consuming, labor-intensive process that also affects work efficiency.

[0010] The invention is further configured such that the plastic recycling assembly includes a fixing rod fixedly connected to the bottom of the connecting block, a support plate fixedly connected between two fixing rods, and adjacent connecting blocks and irregular rods fixedly engaged; a positioning groove is provided on the top of the positioning seat, the injection-molded hardware is inserted into the positioning groove, a sliding groove communicating with the positioning groove is provided through one side of the positioning seat, a limiting groove is provided on the inner side opposite to the sliding groove, an annular push plate is slidably connected to the inner circumferential side of the positioning seat, a connecting plate extending to the outside of the positioning seat and slidably engaged with the sliding groove is fixedly connected to the circumferential side of the annular push plate, and a cylindrical rod slidably engaged with the limiting groove is fixedly connected to the opposite side of the connecting plate.

[0011] The invention is further configured such that a second spring is fixedly connected between the connecting plate and the slide groove, a second electric push rod is fixedly connected to one outer side of the positioning seat, the second electric push rod and the connecting plate are fixedly engaged, and a rectangular groove is provided on the top of the support plate, in which a plastic recycling box is slidably engaged.

[0012] This invention also includes a recycling method for equipment used in the recycling of hardware parts of injection-molded products, comprising the following steps:

[0013] S01: First, insert the plastic seat on the injection-molded hardware into the positioning groove on the positioning seat (the positioning groove on the initial positioning seat is set vertically downward). Then, as the positioning seat is moved upward by the drive component, the positioning seat is simultaneously rotated 180° so that the positioning seat abuts against the groove.

[0014] S02: Then, the first hydraulic cylinder drives the metal recycling assembly to move downward, so that the rectangular heating tube in the metal recycling assembly is sleeved on the injection-molded metal part, and at the same time the bottom of the rectangular heating tube is pressed against the top of the positioning seat.

[0015] S03: Next, the injection-molded hardware is heated by the rectangular heating tube to soften the plastic seat. Then, the hardware recycling assembly is moved upward by the first hydraulic cylinder, which in turn moves the rectangular heating tube upward. The rectangular heating tube moves along the first guide groove on the wedge-shaped guide block through the first push rod, which moves the first push rod and the clamping plate toward the outer wall of the bolt on the injection-molded hardware, thereby clamping the bolt. The rectangular heating tube is then controlled to move upward, which in turn moves the bolt upward through the clamping plate, thereby detaching the bolt from the plastic seat.

[0016] S04: After the bolts are separated, the second hydraulic cylinder is controlled to move the plastic recycling assembly downward. The first spur gear and the first toothed plate on the plastic recycling assembly are used to flip the positioning seat so that the plastic seat is flipped vertically downward. Then, the second electric push rod is activated so that the second electric push rod drives the annular push plate downward through the connecting plate. The annular push plate pushes the plastic seat downward so that the plastic seat is disengaged from the positioning groove, thereby completing the recycling of the plastic seat.

[0017] The present invention has the following beneficial effects: 1. The present invention softens the injection-molded hardware by moving the rectangular heating tube downward. Then, during the upward movement of the rectangular heating tube, the clamping plate moves towards the outer wall of the bolt in conjunction with the use of the limiting component, thereby completing the fixing and clamping of the bolt. The arc-shaped limiting plate abuts against the top of the plastic seat. As the clamping plate continues to move upward, the bolt is separated from the plastic seat, thereby realizing the recycling of the hardware and effectively improving the recycling efficiency and convenience of use of the hardware.

[0018] 2. In this invention, as the rectangular heating tube moves upward driven by the first hydraulic cylinder, the rectangular heating tube further drives the second extension plate and the second toothed plate to move upward. The second toothed plate drives the second spur gear meshing with it to rotate in the opposite direction. The second spur gear drives the lead screw to rotate in the opposite direction. The lead screw drives the moving plate to move closer to the injection-molded hardware, which in turn drives the L-shaped plate and the arc-shaped limiting plate to move closer to the injection-molded hardware. The two arc-shaped limiting plates abut against the top of the plastic seat in the injection-molded hardware. During the separation of the bolt from the plastic seat, the plastic seat is prevented from moving upward with the bolt, thus affecting the normal separation of the bolt.

[0019] 3. After the plastic seat is separated from the bolt by the present invention, the second hydraulic cylinder is controlled to move the plastic recycling component downward. With the cooperation of the first spur gear and the first toothed plate on the plastic recycling component, the positioning seat is moved downward while simultaneously rotating 180° so that the plastic seat is vertically downward. Then, the second electric push rod is activated, which drives the annular push plate downward through the connecting plate. The annular push plate pushes the plastic seat downward, causing the plastic seat to fall out of the positioning groove into the plastic recycling box, thereby completing the recycling of the plastic seat.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1, please refer to Figure 1-18The present invention provides the following technical solution: a device for recycling hardware parts of injection molded products, including a support assembly 1; the support assembly 1 includes an operating table 101, and wedge-shaped guide blocks 102 are symmetrically fixedly connected to the top of the operating table 101; a hardware recycling assembly 2 is fixedly fitted on the support assembly 1, the hardware recycling assembly 2 includes a rectangular heating tube 201, and a first slide rod 202 is slidably connected through one outer side of the rectangular heating tube 201 on opposite sides; one end of the first slide rod 202 is fixedly connected to a clamping plate 203 located inside the rectangular heating tube 201, and the other end of the first slide rod 202 is fixedly connected to a first baffle 204; a first spring 205 is fixedly connected between the first baffle 204 and the rectangular heating tube 201 and sleeved on the first slide rod 202; a first abutment rod 206 that abuts against the wedge-shaped guide block 102 is fixedly connected to the side of the first baffle 204 away from the rectangular heating tube 201.

[0044] A plastic recycling component 3 is slidably installed at the bottom of the operating table 101. The plastic recycling component 3 includes a positioning seat 301. A molded hardware component 302 is inserted and fitted at the top of the positioning seat 301. The molded hardware component 302 is composed of a plastic base 303 and a bolt 304. A rotating shaft 305 is fixedly connected to one of the opposite outer sides of the positioning seat 301. A connecting block 306 is rotatably connected to the end of the rotating shaft 305. A first spur gear 307 is fixedly connected to the circumferential side of the rotating shaft 305. The plastic recycling component 3 also includes a first extension plate 308 symmetrically fixedly connected to the bottom of the operating table 101. A first toothed plate 309 is fixedly connected to the bottom of the first extension plate 308. Adjacent first toothed plates 309 and first spur gears 307 mesh with each other.

[0045] The operation process of this embodiment is as follows: the plastic seat 303 on the injection-molded hardware 302 is inserted into the positioning seat 301 (initially, the injection-molded hardware 302 inserted into the positioning seat 301 is set vertically downward). Then, by controlling the positioning seat 301 to move upward, the first spur gear 307 is simultaneously engaged with the first gear plate 309 during the upward movement of the positioning seat 301, thereby driving the first spur gear 307 to rotate 180° along the first gear plate 309, and thus causing the first spur gear 307 to rotate 180° along the first gear plate 309. 307 drives the positioning seat 301 and the injection molded hardware 302 to rotate 180° through the rotating shaft 305, so that the injection molded hardware 302 rotates from vertically downward to vertically upward. The positioning seat 301 continues to move upward, and the positioning seat 301 drives the first spur gear 307 to move upward and disengage it from the first gear plate 309. At this time, the positioning seat 301 drives the injection molded hardware 302 to move vertically upward, so that the positioning seat 301 moves upward to abut against the operating table 101.

[0046] Before the injection-molded hardware 302 is inserted into the positioning seat 301, the rectangular heating tube 201 is moved downward by controlling it. The rectangular heating tube 201 drives the first abutment 206 downward through the first slide rod 202 and the first baffle 204. The first abutment 206 moves along the wedge-shaped guide block 102 to the inclined position on the wedge-shaped guide block 102 (during the initial movement of the first abutment 206 along the straight part of the wedge-shaped guide block 102, the first spring 205 is always in a compressed state). When the first abutment 206 is at the inclined position of the wedge-shaped guide block 102, under the elastic force of the first spring 205, it drives the clamping plate 203 to move in a direction away from each other. This makes the distance between the two clamping plates 203 greater than the diameter of the bolt 304 on the injection-molded hardware 302. This avoids interference between the two clamping plates 203 and the injection-molded hardware 302 during the process of the rectangular heating tube 201 being sleeved on the injection-molded hardware 302, which would affect the subsequent recycling work.

[0047] After the above-mentioned injection molded hardware 302 is fed, the rectangular heating tube 201 is controlled to move downward so that the rectangular heating tube 201 covers the outside of the injection molded hardware 302. Then the rectangular heating tube 201 is energized and heated to heat and soften the plastic seat 303 on the injection molded hardware 302, making it easier for the bolt 304 to be removed from the plastic seat 303.

[0048] After softening, the plastic seat 303 is kept stationary, and the rectangular heating tube 201 is moved upward. The rectangular heating tube 201 drives the first abutment 206 to move upward along the wedge-shaped guide block 102, thereby moving the first abutment 206 towards the outer wall of the bolt 304. Then, through the first baffle 204 and the first sliding rod 202, the clamping plate 203 moves towards the outer wall of the bolt 304, thus completing the fixing and clamping of the bolt 304. The rectangular heating tube 201 is continued to move upward, so that the rectangular heating tube 201 drives the bolt 304 upward through the clamping plate 203, so that the bolt 304 is separated from the plastic seat 303, thereby realizing the recycling of the hardware.

[0049] Example 2, please refer to Figure 1-18This second embodiment improves upon the first embodiment as follows: the support assembly 1 further includes a support plate 103 fixedly connected to the top of the operating table 101. A first U-shaped plate 104 is fixedly connected to the top of the support plate 103. The first U-shaped plate 104 and two wedge-shaped guide blocks 102 are fixedly engaged. One side of the wedge-shaped guide blocks 102 has a first guide groove 105 that slides with the first abutment rod 206. A second U-shaped plate 106 is fixedly connected to the top of the operating table 101. A first hydraulic cylinder 107 is fixedly connected to the inner top of the second U-shaped plate 106. The output end of the first hydraulic cylinder 107 is fixedly engaged with the rectangular heating tube 201. A first electric push rod 108 is fixedly connected to one side of the support plate 103. An electric push rod 108 is fixedly connected to a hardware recycling box 109 at its output end; a slot 110 is provided at the bottom of the operating table 101, and a notch 111 is provided through the top of the slot 110; a second guide groove 112 is symmetrically provided at the top of the operating table 101; a rectangular hole 113 is symmetrically provided through the top of the operating table 101; a number of support columns 114 are fixedly connected at the bottom of the operating table 101; the hardware recycling assembly 2 also includes a first horizontal plate 207 symmetrically fixedly connected to an outer side of the rectangular heating tube 201; a second extension plate 208 is fixedly connected to the bottom of the first horizontal plate 207; and a second toothed plate 209 that slides with the rectangular hole 113 is fixedly connected to the bottom of the second extension plate 208.

[0050] The top of the operating table 101 is slidably fitted with a limiting component 4. The limiting component 4 includes an L-shaped plate 401 symmetrically slidably connected to the top of the operating table 101. Adjacent L-shaped plates 401 are slidably fitted with a second guide groove 112. An arc-shaped limiting plate 402 adapted to the plastic seat 303 is fixedly connected to the opposite side of each L-shaped plate 401. The limiting component 4 also includes a vertical plate 403 symmetrically fixedly connected to the top of the operating table 101. A lead screw 404 is rotatably connected to one side of the vertical plate 403. A second spur gear 405 is fixedly connected to the circumferential side of the lead screw 404. A moving plate 406 is threadedly connected to the circumferential side of the lead screw 404. Adjacent moving plates 406 and L-shaped plates 401 are fixedly fitted. Adjacent second spur gears 405 are meshed with a second gear plate 209.

[0051] The operation process of this embodiment is as follows: by activating the first hydraulic cylinder 107, the first hydraulic cylinder 107 drives the rectangular heating tube 201 to move, providing power for the movement of the rectangular heating tube 201. During the downward movement of the rectangular heating tube 201 driven by the first hydraulic cylinder 107, the rectangular heating tube 201 synchronously drives the second extension plate 208 and the second toothed plate 209 to move downward. The second toothed plate 209 drives the second spur gear 405 meshing with it to rotate. The second spur gear 405 drives the lead screw 404 to rotate. The lead screw 404 drives the moving plate 406 to move away from the rectangular heating tube 201, thereby driving the L-shaped plate 401 and the arc-shaped limiting plate 402 to move away from the rectangular heating tube 201. The two arc-shaped limiting plates 402 are located outside the rectangular heating tube 201, avoiding interference between the rectangular heating tube 201 and the injection-molded hardware 302 during the process of the rectangular heating tube 201 being sleeved on it.

[0052] During the process of separating the bolt 304 after the injection-molded hardware 302 has softened, the rectangular heating tube 201 is moved upward by the first hydraulic cylinder 107. This causes the rectangular heating tube 201 to further move the second extension plate 208 and the second toothed plate 209 upward. The second toothed plate 209 then drives the second spur gear 405, which meshes with it, to rotate in the opposite direction. The second spur gear 405 then drives the lead screw 404 to rotate in the opposite direction. The lead screw 404 then drives the moving plate 406 to move closer to the injection-molded hardware 302. This, in turn, causes the L-shaped plate 401 and the arc-shaped limiting plate 402 to move closer to the injection-molded hardware 302. The two arc-shaped limiting plates 402 then abut against the top of the plastic seat 303 in the injection-molded hardware 302. This prevents the plastic seat 303 from moving upward with the bolt 304 during the separation of the bolt 304 and the plastic seat 303, thus ensuring the normal separation of the bolt 304.

[0053] After the bolt 304 on the injection-molded hardware 302 is separated, the first electric push rod 108 is controlled to move the hardware recycling box 109 directly below the bolt 304. Then, the first hydraulic cylinder 107 drives the rectangular heating tube 201 to move downward. The rectangular heating tube 201 drives the first abutment 206 to move downward along the wedge-shaped guide block 102. Under the elastic force of the first spring 205, the clamping plate 203 moves away from the bolt 304, so that the bolt 304 is not clamped, and thus the bolt 304 falls into the hardware recycling box 109, thereby completing the recycling of the bolt 304 and improving the convenience of bolt 304 recycling.

[0054] Example 3, please refer to Figure 1-18This fourth embodiment is an improvement on the first embodiment as follows: A drive assembly 5 is fixedly fitted to the bottom of the operating table 101. The drive assembly 5 includes a second hydraulic cylinder 501 fixedly connected to the bottom of the operating table 101. A second horizontal plate 502 is fixedly connected to the output end of the second hydraulic cylinder 501. A shaped rod 503 is symmetrically fixedly connected to one side of the second horizontal plate 502. The drive assembly 5 also includes an L-shaped rod 504 fixedly connected to the bottom of the operating table 101. A positioning plate 505 adapted to the first toothed plate 309 is fixedly connected to the end of the L-shaped rod 504. The plastic recycling assembly 3 also includes a fixing rod 310 fixedly connected to the bottom of the connecting block 306. A support plate 311 is fixedly connected between the two fixing rods 310. Adjacent connecting blocks 306 and shaped rods 503 are fixedly fitted together. A positioning groove 312 is provided on the top of the positioning seat 301. The injection-molded hardware 30... 2. The positioning seat 301 is inserted into the positioning groove 312. A sliding groove 313 communicating with the positioning groove 312 is opened through one side of the positioning seat 301. A limiting groove 314 is opened on the inner side opposite to the sliding groove 313. An annular push plate 315 is slidably connected to the inner circumferential side of the positioning seat 301. A connecting plate 316 extending to the outside of the positioning seat 301 and slidingly engaging with the sliding groove 313 is fixedly connected to the circumferential side of the annular push plate 315. A cylindrical rod 317 slidingly engaging with the limiting groove 314 is fixedly connected to the opposite side of the connecting plate 316. A second spring 318 is fixedly connected between the connecting plate 316 and the sliding groove 313. A second electric push rod 319 is fixedly connected to one outer side of the positioning seat 301. The second electric push rod 319 and the connecting plate 316 are fixedly engaged. A rectangular groove 320 is opened on the top of the support plate 311. A plastic recycling box 6 is slidably engaged in the rectangular groove 320.

[0055] The operation process of this embodiment is as follows: After the bolt 304 is completely separated from the plastic seat 303, the second hydraulic cylinder 501 is controlled to drive the plastic recycling assembly 3 to move downward. With the cooperation of the first spur gear 307 and the first toothed plate 309 on the plastic recycling assembly 3, the positioning seat 301 is moved downward while simultaneously rotating 180°, so that the plastic seat 303 is rotated to vertically downward. Then, the second electric push rod 319 is activated, so that the second electric push rod 319 drives the annular push plate 315 to move downward through the connecting plate 316, so that the annular push plate 315 pushes the plastic seat 303 downward, so that the plastic seat 303 falls out of the positioning groove 312 into the plastic recycling box 6, thereby completing the recycling of the plastic seat 303.

[0056] The working principle of this invention is as follows:

[0057] First, the plastic seat 303 on the injection-molded hardware 302 is inserted into the positioning groove 312 on the positioning seat 301 (the initial positioning groove 312 on the positioning seat 301 is set vertically downward). Then, as the positioning seat 301 is moved upward by the drive component 5, the positioning seat 301 is simultaneously rotated 180°, so that the positioning seat 301 abuts against the groove (110). Then, the hardware recycling component 2 is moved downward by the first hydraulic cylinder 107, so that the rectangular heating tube 201 in the hardware recycling component 2 is sleeved on the injection-molded hardware 302, and at the same time, the bottom of the rectangular heating tube 201 abuts against the top of the positioning seat 301. Then, the rectangular heating tube... 201 heats the injection-molded hardware 302, softening the plastic seat 303. Then, the first hydraulic cylinder 107 drives the hardware recycling assembly 2 to move upward, which in turn drives the rectangular heating tube 201 to move upward. The rectangular heating tube 201 moves along the first guide groove 105 on the wedge-shaped guide block 102 via the first abutment 206, driving the first abutment 206 and the clamping plate 203 to move towards the outer wall of the bolt 304 on the injection-molded hardware 302, thereby clamping the bolt 304. The rectangular heating tube 201 continues to move upward, thereby driving the bolt 304 to move upward via the clamping plate 203, thus completing the detachment of the bolt 304 from the plastic seat 303.

[0058] During the process of separating the bolt 304 after the injection-molded hardware 302 has softened, the rectangular heating tube 201 is moved upward by the first hydraulic cylinder 107. This causes the rectangular heating tube 201 to further move the second extension plate 208 and the second toothed plate 209 upward. The second toothed plate 209 then drives the second spur gear 405, which meshes with it, to rotate in the opposite direction. The second spur gear 405 then drives the lead screw 404 to rotate in the opposite direction. The lead screw 404 then drives the moving plate 406 to move closer to the injection-molded hardware 302. This, in turn, causes the L-shaped plate 401 and the arc-shaped limiting plate 402 to move closer to the injection-molded hardware 302. The two arc-shaped limiting plates 402 then abut against the top of the plastic seat 303 in the injection-molded hardware 302. This prevents the plastic seat 303 from moving upward with the bolt 304 during the separation of the bolt 304 and the plastic seat 303, thus ensuring the normal separation of the bolt 304.

[0059] After the bolt 304 on the injection-molded hardware 302 is separated, the first electric push rod 108 is controlled to move the hardware recycling box 109 directly below the bolt 304. Then, the first hydraulic cylinder 107 drives the rectangular heating tube 201 to move downward. The rectangular heating tube 201 drives the first push rod 206 to move downward along the wedge-shaped guide block 102. Under the elastic force of the first spring 205, the clamping plate 203 moves away from the bolt 304, so that the bolt 304 is not clamped, and thus the bolt 304 falls into the hardware recycling box 109, thereby completing the recycling of the bolt 304 and improving the convenience of recycling the bolt 304.

[0060] After bolt 304 is separated, the second hydraulic cylinder 501 is controlled to move the plastic recycling component 3 downward. With the cooperation of the first spur gear 307 and the first toothed plate 309 on the plastic recycling component 3, the positioning seat 301 is flipped, so that the plastic seat 303 is flipped to vertically downward. Then, the second electric push rod 319 is activated, so that the second electric push rod 319 drives the annular push plate 315 downward through the connecting plate 316. The annular push plate 315 pushes the plastic seat 303 downward, so that the plastic seat 303 is disengaged from the positioning groove 312, thereby completing the recycling of the plastic seat 303.
