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

[0013] S01: First, insert the plastic seat on the injection molding hardware into the positioning groove on the positioning seat (the positioning groove on the initial positioning seat is vertically downwardly arranged), and then, while the positioning seat is driven upward by the driving assembly, the positioning seat is synchronously flipped 180 degrees so that the positioning seat rests against the notch;

[0014] S02: Then, the hardware recycling assembly is driven downward by the first hydraulic cylinder, so that the rectangular heating tube in the hardware recycling assembly is sleeved on the injection molding hardware, 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 molding hardware is heated by the rectangular heating tube to soften the plastic seat, and then the hardware recovery assembly is driven to move upward by the first hydraulic cylinder, thereby driving the rectangular heating tube to move upward, so that the rectangular heating tube moves along the first guide groove on the wedge-shaped guide block through the first push rod, driving the first push rod and the clamping plate to move toward the outer wall of the bolt on the injection molding hardware, thereby completing the clamping of the bolt, and continuing to control the rectangular heating tube to move upward, thereby driving the bolt to move upward through the clamping plate, thereby completing the detachment of the bolt from the plastic seat;

[0016] S04: After the bolts are separated, the second hydraulic cylinder is controlled to drive the plastic recovery component to move downward, and the first spur gear and the first toothed plate on the plastic recovery component are used in cooperation to flip the positioning seat so that the plastic seat is flipped vertically downward. Then, the second electric push rod is started to drive the annular push plate to move downward through the connecting plate, so that the annular push plate pushes the plastic seat downward, so that the plastic seat is disengaged from the positioning groove, thereby completing the recovery 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, in the process of the rectangular heating tube moving upward, the limit assembly is used to move the clamping plate toward the outer wall of the bolt, thereby completing the fixed clamping of the bolt. The arc-shaped limit plate abuts against the top of the plastic seat, and the clamping plate continues to move upward to separate the bolt from the plastic seat, thereby realizing the recycling of the hardware, effectively improving the recycling efficiency and convenience of use of the hardware.

[0018] 2. In the process of the rectangular heating tube being driven upward by the first hydraulic cylinder, the rectangular heating tube further drives the second extension plate and the second tooth plate to move upward, so that the second tooth plate drives the second spur gear meshing therewith to rotate in the opposite direction, and the second spur gear drives the screw rod to rotate in the opposite direction, so that the screw rod drives the movable plate to move in the direction close to the injection molding hardware, and then drives the L-shaped plate and the arc-shaped limit plate to move in the direction close to the injection molding hardware, so that the two arc-shaped limit plates are in contact with the top of the plastic seat in the injection molding hardware, so that in the process of separation of the bolt and the plastic seat, the plastic seat is prevented from moving upward with the bolt, thereby affecting the normal separation of the bolt.

[0019] 3. After the present invention separates the plastic from the plastic seat by bolts, it then controls the second hydraulic cylinder to drive the plastic recovery assembly to move downward. Through the cooperation of the first spur gear and the first toothed plate on the plastic recovery assembly, the positioning seat is moved downward and simultaneously flipped 180°, so that the plastic seat flips vertically downward. Then, the second electric push rod is started, so that the second electric push rod drives the annular push plate to move downward through the connecting plate, so that the annular push plate pushes the plastic seat to move downward, so that the plastic seat falls off from the positioning groove into the plastic recovery box, thereby completing the recovery of the plastic seat.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1-18The present invention provides the following technical solutions: a device for recycling hardware parts of injection molded products in molds, comprising a support component 1; the support component 1 comprises an operating table 101, and a wedge-shaped guide block 102 is symmetrically fixedly connected to the top of the operating table 101; a hardware recycling component 2 is fixedly matched with the support component 1, and the hardware recycling component 2 comprises a rectangular heating tube 201, and the opposite outer side surfaces of the rectangular heating tube 201 are penetrated by a first slide bar 202 that is slidably connected, one end of the first slide bar 202 is fixedly connected to a clamping plate 203 located inside the rectangular heating tube 201, and the other end of the first slide bar 202 is fixedly connected to a first baffle 204, and a first spring 205 mounted on the first slide bar 202 is fixedly connected between the first baffle 204 and the rectangular heating tube 201, and a first stop bar 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 arranged at the bottom of the operating table 101, and the plastic recycling component 3 includes a positioning seat 301, and the top of the positioning seat 301 is plugged with an injection molding hardware 302, and the injection molding hardware 302 is composed of a plastic seat 303 and a bolt 304. The opposite outer side surfaces of the positioning seat 301 are fixedly connected with a rotating shaft 305, and the end of the rotating shaft 305 is rotatably connected with a connecting block 306, and the peripheral side surface of the rotating shaft 305 is fixedly connected with a first straight gear 307; the plastic recycling component 3 also includes a first extension plate 308 symmetrically fixedly connected to the bottom of the operating table 101, and the bottom of the first extension plate 308 is fixedly connected with a first tooth plate 309, and the adjacent first tooth plates 309 are meshed with the first straight gear 307.

[0045] The operation process of this embodiment is as follows: the plastic seat 303 on the injection molding hardware 302 is plugged into the positioning seat 301 (the injection molding hardware 302 initially plugged into the positioning seat 301 is vertically downwardly arranged), and then, by controlling the positioning seat 301 to move upward, during the upward movement of the positioning seat 301, the first spur gear 307 is synchronously meshed with the first tooth plate 309, thereby driving the first spur gear 307 to rotate 180 degrees along the first tooth plate 309, thereby causing ... 307 drives the positioning seat 301 and the injection molding hardware 302 to rotate 180 degrees through the rotating shaft 305, so that the injection molding hardware 302 rotates from vertical downward to vertical upward, and continues to control the positioning seat 301 to move upward, and drives the first straight gear 307 to move upward and disengage from the meshing with the first tooth plate 309 through the positioning seat 301. At this time, the positioning seat 301 drives the injection molding hardware 302 to move vertically upward, so that the positioning seat 301 moves upward to contact with the operating table 101;

[0046] Before the injection molding hardware 302 is plugged into the positioning seat 301, the rectangular heating tube 201 is first controlled to move downward, so that the rectangular heating tube 201 drives the first push rod 206 to move downward through the first sliding rod 202 and the first baffle 204, so that the first push rod 206 moves along the wedge-shaped guide block 102 to the inclined position on the wedge-shaped guide block 102 (in the process of the first push rod 206 initially moving along the straight part of the wedge-shaped guide block 102, the first spring 205 is always in a compressed state). When the first push rod 206 is at the inclined position of the wedge-shaped guide block 102, under the elastic force of the first spring 205, the clamping plate 203 is driven to move away from each other, so that the distance between the two clamping plates 203 is greater than the diameter of the bolt 304 on the injection molding hardware 302, thereby avoiding the interference between the two clamping plates 203 and the injection molding hardware 302 during the process of the rectangular heating tube 201 being sleeved on the injection molding hardware 302, thereby affecting the subsequent recycling work;

[0047] After the injection molding hardware 302 is loaded, the rectangular heating tube 201 is controlled to move downward so that the rectangular heating tube 201 covers the outside of the injection molding hardware 302. Then, the rectangular heating tube 201 is powered on to heat the plastic seat 303 on the injection molding hardware 302, thereby heating and softening the bolt 304 so that the bolt 304 can be easily separated from the plastic seat 303.

[0048] After softening, the plastic seat 303 is kept stationary, and the rectangular heating tube 201 is controlled to move upward, so that the rectangular heating tube 201 drives the first push rod 206 to move upward along the wedge-shaped guide block 102, thereby driving the first push rod 206 to move toward the outer wall direction close to the bolt 304, and then driving the clamping plate 203 to move toward the outer wall direction close to the bolt 304 through the first baffle plate 204 and the first slide bar 202, thereby completing the fixed clamping of the bolt 304, and continuing to control the rectangular heating tube 201 to move upward, so that the rectangular heating tube 201 drives the bolt 304 to move upward through the clamping plate 203, so that the bolt 304 is separated from the plastic seat 303, thereby realizing the recovery of the hardware.

[0049] For example 2, please refer to Figure 1-18, the second embodiment is improved on the basis of the first embodiment as follows: the support assembly 1 also includes a support plate 103 fixedly connected to the top of the operating table 101, the top of the support plate 103 is fixedly connected to a first U-shaped plate 104, the first U-shaped plate 104 and the two wedge-shaped guide blocks 102 are fixedly matched, and one side of the wedge-shaped guide block 102 is provided with a first guide groove 105 that slides with the first push rod 206; the top of the operating table 101 is fixedly connected to a second U-shaped plate 106, the inner top of the second U-shaped plate 106 is fixedly connected to a first hydraulic cylinder 107, and the output end of the first hydraulic cylinder 107 is fixedly matched with the rectangular heating tube 201; one side of the support plate 103 is fixedly connected to a first electric push rod 108, the first U-shaped plate 104 and the two wedge-shaped guide blocks 102 are fixedly matched, and the first guide groove 105 that slides with the first push rod 206 is opened on one side of the wedge-shaped guide block 102; the top of the operating table 101 is fixedly connected to a second U-shaped plate 106, the inner top of the second U-shaped plate 106 is fixedly connected to a first hydraulic cylinder 107, and the output end of the first hydraulic cylinder 107 is fixedly matched with the rectangular heating tube 201; one side of the support plate 103 is fixedly connected to a first electric push rod 108, An output end of an electric push rod 108 is fixedly connected to a hardware recycling box 109; a notch 110 is provided at the bottom of the operating table 101, a notch 111 is penetrated through the inner top of the notch 110, a second guide groove 112 is symmetrically provided at the top of the operating table 101, a rectangular hole 113 is symmetrically penetrated through the top of the operating table 101, a plurality of support columns 114 are fixedly connected to the bottom of the operating table 101, and the hardware recycling component 2 also includes a first horizontal plate 207 symmetrically fixedly connected to an outer side opposite to 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 tooth plate 209 slidably matched 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 matched with a limit assembly 4, which includes an L-shaped plate 401 symmetrically slidably connected to the top of the operating table 101, adjacent L-shaped plates 401 are slidably matched with the second guide groove 112, and the opposite side of the L-shaped plate 401 is fixedly connected with an arc-shaped limit plate 402 adapted to the plastic seat 303; the limit assembly 4 also includes a vertical plate 403 symmetrically fixedly connected to the top of the operating table 101, one side of the vertical plate 403 is rotatably connected with a screw rod 404, the peripheral side surface of the screw rod 404 is fixedly connected with a second spur gear 405, the peripheral side surface of the screw rod 404 is threadedly connected with a movable plate 406, adjacent movable plates 406 and L-shaped plates 401 are fixedly matched, and adjacent second spur gears 405 are meshingly matched with the second tooth plate 209.

[0051] The operation process of this embodiment is as follows: by starting 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. In the process of the rectangular heating tube 201 being driven downward by the first hydraulic cylinder 107, the rectangular heating tube 201 synchronously drives the second extension plate 208 and the second tooth plate 209 to move downward, so that the second tooth plate 209 drives the second spur gear 405 meshing therewith to rotate, so that the second spur gear 405 drives the screw rod 404 to rotate, so that the screw rod 404 drives the moving plate 406 to move away from the rectangular heating tube 201, and then drives the L-shaped plate 401 and the arc-shaped limit plate 402 to move away from the rectangular heating tube 201, so that the two arc-shaped limit plates 402 are located on the outside of the rectangular heating tube 201, so as to avoid the rectangular heating tube 201 from interfering with the injection molding hardware 302 during the process of being sleeved on the injection molding hardware 302;

[0052] When the injection molding hardware 302 is softened and the bolt 304 is separated, the rectangular heating tube 201 is driven upward by the first hydraulic cylinder 107, so that the rectangular heating tube 201 further drives the second extension plate 208 and the second tooth plate 209 to move upward, so that the second tooth plate 209 drives the second spur gear 405 meshing therewith to rotate in the opposite direction, so that the second spur gear 405 drives the screw rod 404 to rotate in the opposite direction, so that the screw rod 404 drives the moving plate 406 to move in the direction close to the injection molding hardware 302, and then drives the L-shaped plate 401 and the arc-shaped limiting plate 402 to move in the direction close to the injection molding hardware 302, so that the two arc-shaped limiting plates 402 are against the top of the plastic seat 303 in the injection molding hardware 302, so that in the process of separating the bolt 304 from the plastic seat 303, it is prevented that the plastic seat 303 moves upward with the bolt 304, thereby affecting the normal separation of the bolt 304;

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

A rectangular groove 320 is formed on the top of the supporting plate 311, and a plastic recycling box 6 is slidably matched 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 recovery component 3 to move downward, and the first spur gear 307 and the first tooth plate 309 on the plastic recovery component 3 are used in cooperation to achieve the process of the positioning seat 301 moving downward, and at the same time flipping 180°, so that the plastic seat 303 flips to vertically downward, and then, the second electric push rod 319 is started, 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 to move downward, so that the plastic seat 303 falls off from the positioning groove 312 into the plastic recovery box 6, thereby completing the recovery of the plastic seat 303.

[0056] The working principle of the present invention is:

[0057] First, the plastic seat 303 on the injection molding hardware 302 is inserted into the positioning groove 312 on the positioning seat 301 (the positioning groove 312 on the initial positioning seat 301 is vertically downwardly arranged). Then, in the process of driving the positioning seat 301 to move upward by the driving component 5, the positioning seat 301 is synchronously flipped 180 degrees, so that the positioning seat 301 is against the notch 110; then, the hardware recycling component 2 is driven 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 molding hardware 302, and at the same time, the bottom of the rectangular heating tube 201 is pressed against the top of the positioning seat 301; then, the rectangular heating tube 2 01 heats the injection molding hardware 302 to soften the plastic seat 303, and then drives the hardware recovery component 2 to move upward through the first hydraulic cylinder 107, thereby driving the rectangular heating tube 201 to move upward, so that the rectangular heating tube 201 moves along the first guide groove 105 on the wedge-shaped guide block 102 through the first push rod 206, driving the first push rod 206 and the clamping plate 203 to move toward the outer wall of the bolt 304 on the injection molding hardware 302, thereby completing the clamping of the bolt 304, and continuing to control the rectangular heating tube 201 to move upward, thereby driving the bolt 304 to move upward through the clamping plate 203, thereby completing the separation of the bolt 304 from the plastic seat 303;

[0058] When the injection molding hardware 302 is softened and the bolt 304 is separated, the rectangular heating tube 201 is driven upward by the first hydraulic cylinder 107, so that the rectangular heating tube 201 further drives the second extension plate 208 and the second tooth plate 209 to move upward, so that the second tooth plate 209 drives the second spur gear 405 meshing therewith to rotate in the opposite direction, so that the second spur gear 405 drives the screw rod 404 to rotate in the opposite direction, so that the screw rod 404 drives the moving plate 406 to move in the direction close to the injection molding hardware 302, and then drives the L-shaped plate 401 and the arc-shaped limiting plate 402 to move in the direction close to the injection molding hardware 302, so that the two arc-shaped limiting plates 402 are against the top of the plastic seat 303 in the injection molding hardware 302, so that in the process of separating the bolt 304 from the plastic seat 303, it is prevented that the plastic seat 303 moves upward with the bolt 304, thereby affecting the normal separation of the bolt 304;

[0059] After the bolt 304 on the injection molding hardware 302 is separated, the hardware recovery box 109 is driven to move directly below the bolt 304 by controlling the first electric push rod 108, and then the rectangular heating tube 201 is driven to move downward by the first hydraulic cylinder 107. 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 is driven to move away from the bolt 304, so that the bolt 304 is not clamped, so that the bolt 304 falls into the hardware recovery box 109, and then the bolt 304 is recovered, thereby improving the convenience of recovering the bolt 304.

[0060] After the bolt 304 is separated, the second hydraulic cylinder 501 is controlled to drive the plastic recovery component 3 to move downward, and the first spur gear 307 and the first tooth plate 309 on the plastic recovery component 3 are used in cooperation to realize the flipping of the positioning seat 301, so that the plastic seat 303 is flipped to be vertically downward, and then, the second electric push rod 319 is started, 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 to move downward, so that the plastic seat 303 is disengaged from the positioning groove 312, thereby completing the recovery of the plastic seat 303.
