[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-13 As shown, an automatic production line for manufacturing and molding automobile bumpers includes a fixed die table and a movable die table 1, a box seat 2 and a flap 8 hingedly arranged on one side thereof, and a stripping plate 83 is movably arranged on the flap 8;

[0041] A trigger unit is provided on the movable mold table 1, and the trigger unit includes:

[0042] A push plate 12, which pushes the flap 8 downward and away from the movable die table 1 when the movable die table 1 approaches the fixed die table;

[0043] The elastic component is used to reset the flap 8 so that the stripping plate 83 is movable on the movable die table 1 to push the bumper to strip;

[0044] The top array of the cassette holder 2 is provided with a transfer unit, which includes a driving roller 4 that is driven to move the bumper.

[0045] Specifically, the outer wall of one side of the box seat 2 is symmetrically provided with side panels 24 , and the flap 8 is hingedly provided between the two side panels 24 . The elastic component includes a first torsion spring 99 and a second torsion spring 82. The torsion force of the first torsion spring 99 is greater than the torsion force of the second torsion spring 82, so that when the flap 8 is flipped up, the end of the stripping plate 83 is driven to slide on the bottom of the mold table on the movable mold table 1. The first torsion spring 99 is sleeved on the hinge axis of the flap 8, and the first end of the first torsion spring 99 is fixedly installed on the side plate 24, and the second end of the first torsion spring 99 is fixedly installed on the flap 8. The first torsion spring 99 drives the flap 8 to flip up, and a stopper 81 is provided at one end of the flap 8 opposite to the box seat 2. The stripping plate 83 is hingedly arranged on the stopper 81. The second torsion spring 82 is sleeved on the hinge axis of the stripping plate 83. The first end of the second torsion spring 82 is fixedly installed on the stopper 81, and the second end of the second torsion spring 82 is fixedly installed on the stripping plate 83. The second torsion spring 82 drives the stripping plate 83 to flip over to approach the stopper 81. Then, when the flap 8 is turned up, the sponge push pad 84 provided at the end of the stripper plate 83 moves on the bottom of the mold table on the movable mold table 1, and then when the sponge push pad 84 moves on the bottom of the mold table on the movable mold table 1, it pushes the plastic bumper injection-molded on the mold table.

[0046] Furthermore, the push plate 12 is fixedly mounted on the movable mold table 1. When the push plate 12 moves with the movable mold table 1, the end of the push plate 12 pushes the flip plate 8 close to one end of the box seat 2 to make the flap 8 flip down. When the injection molding of the movable mold table 1 is completed, the movable mold table 1 is away from the fixed mold table, and the first torsion spring 99 drives the flap 8 to return to its original position and flip up so that the sponge push pad 84 moves along the bottom of the mold table on the movable mold table 1 to push the material. The fallen bumper moves and falls onto the driving roller 4, and then is driven to rotate through multiple driving rollers 4 to transport the bumper out of the injection molding machine.

[0047] Furthermore, how the injection molding machine drives the movable die table 1 to approach the fixed die table to achieve injection molding and material return is a well-known technical means for those skilled in the art and will not be elaborated here.

[0048] Furthermore, the driving method of the above-mentioned driving rollers 4 can be to drive multiple driving rollers 4 to rotate through a motor and a leather wheel; or to drive multiple driving rollers 4 to rotate through an electric push rod in conjunction with gears and racks; or any method known to those skilled in the art to drive multiple driving rollers 4 to rotate.

[0049] In the above technology, when the movable mold table 1 is approached to the fixed mold table for injection molding of the automobile bumper, the push plate 12 moves with the movable mold table 1, and then the push plate 12 is used to push the flap 8 down and away from the movable mold table 1, thereby preventing the flap 8 from affecting the injection molding. After the injection molding is completed and the movable mold table 1 is away from the fixed mold table, the push plate 12 is separated from the push on the flap 8, and then the elastic component is used to reset the flap 8 and slide through one end of the stripping plate 83 located at the bottom of the upper mold table of the movable mold table 1 to push the bumper to remove the material, and then the bumper moves and falls on the driving roller 4 to be transported out of the injection molding machine, thereby avoiding the danger of manual entry into the injection molding machine. At the same time, compared with the robot arm, its structure is simple, and it is easy to maintain and use.

[0050] As an embodiment further provided by the present invention, a pull rod 86 is hingedly provided on one side of the stripping plate 83, a driving block 87 is slidably provided on the outer wall of one side of the flap 8, and a first end of the pull rod 86 is hingedly provided on the driving block 87;

[0051] It also includes a driving unit that drives the driving block 87 to slide to cooperate with the pull rod 86 to pull the stripping plate 83 to move relative to the flap 8.

[0052] Specifically, a slide groove 85 is opened on one side of the flap 8, and the driving block 87 is slidably arranged in the slide groove 85. When the driving unit drives the driving block 87 to slide close to the material stripping plate 83, the driving block 87 cooperates with the pull rod 86 to push the material stripping plate 83 to flip away from the flap 8, thereby increasing the angle between the material stripping plate 83 and the flap 8. Similarly, when the driving unit drives the driving block 87 to slide away from the material stripping plate 83, the driving block 87 cooperates with the pull rod 86 to pull the material stripping plate 83 to flip close to the flap 8.

[0053] Therefore, when the movable die table 1 is moved close to the fixed die table for the injection molding of the automobile bumper, the push plate 12 moves with the movable die table 1, and then the push plate 12 is used to push the flap 8 downward and away from the movable die table 1. At the same time, the driving unit drives the driving block 87 to slide away from the stripping plate 83. At this time, the driving block 87 cooperates with the pull rod 86 to pull the stripping plate 83 to flip close to the flap 8, thereby preventing the stripping plate 83 from affecting the injection molding of the movable die table 1. When the movable die table 1 is away from the fixed die table, at this time The push plate 12 disengages from the push on the flap 8, and then uses the first torsion spring 99 to reset the flap 8 to flip up. At the same time, the drive unit drives the drive block 87 to slide close to the stripping plate 83. At this time, the drive block 87 cooperates with the pull rod 86 to push the stripping plate 83 to flip away from the flap 8, so that one end of the stripping plate 83 is located at the bottom of the upper mold table of the movable mold table 1. As the flap 8 flips up, one end of the stripping plate 83 slides to the bottom of the mold table to push the bumper off the movable mold table 1.

[0054] As another embodiment provided by the present invention, the driving unit includes a force-bearing rod 89 hingedly arranged on one side of the flap 8 and a knocking rod 98 slidably arranged on the box seat 2, the knocking rod 98 and the push plate 12 maintain opposite movement to hit the force-bearing rod 89, and the force-bearing rod 89 maintains synchronous movement with the driving block 87.

[0055] Specifically, a movable rod 88 is hingedly provided on the driving block 87, and the first end of the movable rod 88 is hingedly provided on the first end of the force-bearing rod 89, and the knocking rod 98 is slidably provided in the side plate 24 on the box seat 2, and the first reversing rod 9 and the second reversing rod 95 are hingedly provided in the side plate 24, and a transverse groove 92 is provided on the first reversing rod 9, and a pad 93 is slidably provided on the outer wall of the first reversing rod 9, and a reversing spring 94 is sleeved on the outer wall of the first reversing rod 9, and the first end of the reversing spring 94 is fixedly installed on the pad Plate 93, and the second end of the reversing spring 94 is fixedly mounted on the mounting plate 91 set on the first reversing rod 9, the first end of the second reversing rod 95 is fixedly mounted with a movable shaft 96, and the movable shaft 96 is movably set in the transverse groove 92, a reversing connecting rod 97 is hingedly set on the movable shaft 96, and the first end of the reversing connecting rod 97 is hingedly set on the knocking rod 98, a limit plate 11 is symmetrically set on the top of the push plate 12, and the second end of the second reversing rod 95 is movably set between the two limit plates 11.

[0056] Furthermore, when the movable mold table 1 approaches the fixed mold table for automobile bumper injection molding, the push plate 12 moves with the movable mold table 1, and then the push plate 12 is used to approach the flap 8. When the push plate 12 pushes the flap 8 to make the flap 8 flip down, one of the limit plates 11 is used to push the second end of the second reversing rod 95. When the second reversing rod 95 flips over, the movable shaft 96 is movably arranged in the transverse groove 92 and pushes the pad 93. At the same time, the pad 93 squeezes the reversing spring 94 to make the reversing spring 94 accumulate force. As the second reversing rod 95 flips over, the reversing spring 94 accumulates force to the maximum value. Then, when one of the limit plates 11 continues to push the second end of the second reversing rod 95, the reversing spring 94 releases the accumulated force to push the pad 93, and then pushes the movable shaft 96 through the pad 93 to quickly flip the second reversing rod 95. Fig.12 As shown in FIG. 1 , when the reversing spring 94 pushes the second reversing rod 95 to flip, the movable shaft 96 cooperates with the reversing connecting rod 97 to push the knocking rod 98 to slide, and then the knocking rod 98 hits the second end of the force-bearing rod 89. When the knocking rod 98 hits the second end of the force-bearing rod 89, Figure 3 As shown, the force rod 89 flips to cooperate with the movable rod 88 to pull the driving block 87 to slide away from the stripping plate 83. At this time, the driving block 87 cooperates with the pull rod 86 to pull the stripping plate 83 to flip close to the flap 8, thereby preventing the stripping plate 83 from affecting the injection molding of the movable mold table 1.

[0057] When the injection molding is completed and the movable mold table 1 is away from the fixed mold table, the push plate 12 is disengaged from the push on the flap 8, and then the first torsion spring 99 is used to reset the flap 8 and flip it up. At the same time, the other limit plate 11 moves with the push plate 12 to move away from the box seat 2. At this time, the other limit plate 11 pushes the second end of the second reversing rod 95 to make the second reversing rod 95 flip again. At the same time, the movable shaft 96 slides in the transverse groove 92 again to make the reversing spring 94 accumulate force again. Then, the reversing spring 94 accumulates force to the maximum value again and is accompanied by another limit plate 11 pushing the second end of the second reversing rod 95, so that the reversing spring 94 begins to release the accumulated force and push the second reversing rod 95 to flip quickly. At this time, the second reversing rod 95 cooperates with the reversing connecting rod 97 again to pull the knocking rod 98 to slide. At this time, the knocking rod 98 quickly moves away from the second end of the force-bearing rod 89, and then cooperates with the second torsion spring 82 to drive the stripping plate 83 to flip to approach the stop table 81. Then, along with the upward flipping of the flap 8, the sponge push pad 84 provided at the end of the stripping plate 83 moves to the bottom of the mold table on the movable mold table 1 to push the plastic bumper injection molded on the mold table to remove the material.

[0058] As another embodiment provided by the present invention, a piston plate 3 is slidably disposed in the cartridge seat 2, and the two cooperate to form a piston cavity, and a guide rod 35 fixedly mounted on the piston plate 3 is slidably disposed on the cartridge seat 2;

[0059] A gear transmission assembly is also included, which is used to keep the plurality of driving rollers 4 and the guide rods 35 in transmission.

[0060] Specifically, the top of the box seat 2 is provided with a plurality of one-way air valves 26 connected to the piston cavity, and the top of the box seat 2 is provided with an air inlet 25, and the outer wall of the piston plate 3 is provided with a sealing ring 33, and the sealing ring 33 is used to improve the sealing between the piston plate 3 and the inner wall of the box seat 2. Therefore, when the piston plate 3 is driven to move upward, the plurality of one-way air valves 26 are opened to allow the gas in the piston cavity to be discharged through the one-way air valves 26 and the air inlet 25, and then when the piston plate 3 is driven to move downward, the plurality of one-way air valves 26 are closed, and the guide rod 35 is slidably provided on the box seat 2 and cooperates with the gear transmission assembly to drive the plurality of driving rollers 4 to rotate in the same direction to transfer the plastic bumper on the top of the driving roller 4 out of the injection molding machine.

[0061] Furthermore, the piston plate 3 may be driven to move up or down by an electric push rod; or by a nut, a screw rod and a motor; or by any other method known to those skilled in the art to drive the piston plate 3 to move up or down.

[0062] Furthermore, the gear transmission assembly can be a connecting rod with a rack and a gear; it can also be a belt, a connecting rod, a rack and a gear; or it can be any method known to those skilled in the art to maintain transmission of multiple drive rollers 4 and guide rods 35.

[0063] As another embodiment provided by the present invention, the gear transmission assembly includes double-track pulleys 41 respectively fixedly mounted on one end of the shaft of the driving roller 4 and a force-bearing gear 42 fixedly mounted on the shaft of one of the driving rollers 4, and belt transmission is provided between every two adjacent double-track pulleys 41.

[0064] Specifically, a bracket 21 is disposed on the top of the cassette holder 2, and a plurality of driving rollers 4 are axially rotatably disposed on the bracket 21, an extension frame 22 is symmetrically disposed on the top of the bracket 21, and a plurality of auxiliary rollers 23 are axially rotatably disposed on the extension frame 22, such as Figure 8 As shown, a main shaft 44 is axially rotatably provided on the bracket 21, a main gear 45 and a large gear 43 are fixedly installed on the outer wall of the main shaft 44, a main rack 46 is slidably provided on the auxiliary plate 27 fixedly installed on the bracket 21, and the main rack 46 and the main gear 45 are meshed, and the large gear 43 and the force-bearing gear 42 are meshed. Fig.10 As shown, a mounting seat 36 is fixedly mounted on the top of the guide rod 35 , and a material ejection rod 47 is hingedly arranged on the mounting seat 36 , and a first end of the material ejection rod 47 is hingedly arranged on the main rack 46 .

[0065] Further, when the guide rod 35 is driven downward with the piston plate 3, the piston plate 3 cooperates with the material-removing rod 47 to pull the main rack 46 to move. At this time, the main rack 46 slides on the auxiliary plate 27 and the main rack 46 is meshed with the main gear 45. At this time, the main shaft 44 rotates to drive the large gear 43 to rotate, and then the large gear 43 and the force gear 42 are meshed to rotate one of the driving rollers 4. When one of the driving rollers 4 rotates, the belt transmission is transmitted between every two adjacent double-track pulleys 41, such as Figure 4 As shown, multiple driving rollers 4 are rotated synchronously to drive the bumpers on the driving rollers 4 to move and transport materials.

[0066] As the optimal embodiment provided by the present invention, a collision block 32 is slidably arranged on the box seat 2, and the first end of the connecting rod 31 hingedly arranged on the collision block 32 is hingedly arranged at the bottom of the piston plate 3, the collision block 32 is located on the moving path of the push plate 12, and a return spring 34 is arranged in the piston cavity.

[0067] Specifically, the impact block 32 is slidably disposed on the outer wall of the box seat 2 located on the side of the flap 8 , the first end of the return spring 34 is fixedly mounted on the piston plate 3 , and the second end of the return spring 34 is fixedly mounted on the box seat 2 .

[0068] Furthermore, when the movable mold table 1 approaches the fixed mold table for automobile bumper injection molding, the push plate 12 moves with the movable mold table 1, and then the push plate 12 is used to approach the flap 8. When the push plate 12 pushes the flap 8 to make the flap 8 flip down, one of the limit plates 11 is used to push the second end of the second reversing rod 95. When the second reversing rod 95 flips over, the movable shaft 96 is movably arranged in the transverse groove 92 and pushes the pad 93. At the same time, the pad 93 squeezes the reversing spring 94 to make the reversing spring 94 accumulate force. As the second reversing rod 95 flips over, the reversing spring 94 accumulates force to the maximum value. Then, when one of the limit plates 11 continues to push the second end of the second reversing rod 95, the reversing spring 94 releases the accumulated force to push the pad 93, and then pushes the movable shaft 96 through the pad 93 to quickly flip the second reversing rod 95. Fig.12 As shown in FIG. 1 , when the reversing spring 94 pushes the second reversing rod 95 to flip, the movable shaft 96 cooperates with the reversing connecting rod 97 to push the knocking rod 98 to slide, and then the knocking rod 98 hits the second end of the force-bearing rod 89. When the knocking rod 98 hits the second end of the force-bearing rod 89, Figure 3As shown, the force rod 89 turns over to cooperate with the movable rod 88 to pull the driving block 87 to slide away from the stripping plate 83. At this time, the driving block 87 cooperates with the pull rod 86 to pull the stripping plate 83 to turn close to the flap 8, thereby preventing the stripping plate 83 from affecting the injection molding of the movable mold table 1. At the same time, as the push plate 12 slides toward the side of the box seat 2, the end of the push plate 12 hits the impact block 32. When the impact block 32 is hit and slides, the impact block 32 cooperates with the connecting rod 31 to push the piston plate 3 to slide upward. At the same time, when the piston plate 3 slides, multiple one-way air valves 26 are opened to allow the gas in the piston cavity to be discharged through the one-way air valve 26 and the air inlet 25, and the return spring 34 is squeezed and stored.

[0069] When the injection molding is completed and the movable mold table 1 is away from the fixed mold table, the push plate 12 is separated from the push of the flap plate 8 and the impact block 32, and then the first torsion spring 99 is used to reset the flap 8 and flip it up. At the same time, the other limit plate 11 moves with the push plate 12 to move away from the box seat 2. At this time, the other limit plate 11 pushes the second end of the second reversing rod 95 to make the second reversing rod 95 flip again. At the same time, the movable shaft 96 slides in the transverse groove 92 again to make the reversing spring 94 accumulate force again, and then the reversing spring 94 accumulates force to the maximum value again and is accompanied by another limit plate 11 pushing the second end of the second reversing rod 95, so that the reversing spring 94 begins to release the accumulated force and push the second reversing rod 95 to flip quickly. At this time, the second reversing rod 95 cooperates with the reversing connecting rod 97 again to pull the knocking rod 98 to slide. At this time, the knocking rod 98 quickly moves away from the second end of the force-bearing rod 89, and then cooperates with the second torsion spring 82 to drive the stripping plate 83 to flip to approach the stop table 81. Then, along with the upward flipping of the flap 8, the sponge push pad 84 provided at the end of the stripping plate 83 moves to the bottom of the mold platform on the movable mold platform 1, so as to push the plastic bumper molded on the mold platform to strip the material. At the same time, because the push plate 12 is separated from the push of the impact block 32, the reset spring 34 releases the stored force to push the piston plate 3 to slide downward. At this time, multiple one-way air valves 26 are closed, so that the external air enters the piston cavity along the air inlet 25. At this time, the piston plate 3 moves slowly downward. When the piston plate 3 moves downward, the piston plate 3 cooperates with the stripping rod 47 to pull the main rack 46 to move. At this time, the main rack 46 slides on the auxiliary plate 27 and the main rack 46 and the main gear 45 are meshed. At this time, the main shaft 44 rotates to drive the large gear 43 to rotate, and then the large gear 43 and the force-bearing gear 42 are meshed to rotate one of the drive rollers 4. When one of the drive rollers 4 rotates, the belt transmission is transmitted between each two adjacent double-track pulleys 41, such as Figure 4As shown, the plurality of driving rollers 4 rotate synchronously, and then when the stripping plate 83 strips the plastic bumper molded on the mold table onto the driving roller 4, the plurality of driving rollers 4 rotate to move the bumper thereon, and when the stripping plate 83 strips the bumper onto the driving roller 4 through the slow drop of the piston plate 3, the driving roller 4 still keeps rotating, thereby moving the material out of the injection molding machine, and the large gear 43 and the force gear 42 are meshed as shown in FIG. Figure 8 As shown, the number of teeth of the large gear 43 is greater than that of the force-bearing gear 42 , thereby increasing the number of rotations of the force-bearing gear 42 .

[0070] As another embodiment provided by the present invention, a bellows 5 is symmetrically arranged on the top of the box seat 2, and the air outlet on the bellows 5 is located below the driving roller 4 to blow air to the bumper.

[0071] Specifically, the outer wall on one side of the bellows 5 is respectively provided with a fan group 61, and the fan group 61 blows air into the bellows 5 respectively. The air outlet of the bellows 5 is located at the top of the bellows 5. Then, when the stripping plate 83 removes the bumper onto the driving roller 4, the fan group 61 is turned on to blow air through the air outlet of the bellows 5 to cool the bumper, and at the same time, remove the plastic microparticle powder remaining on the surface of the plastic bumper.

[0072] As another embodiment provided by the present invention, a plurality of air ducts 52 are arranged in the bellows 5, and the air outlet array of the air duct 52 is hingedly provided with a plurality of blades 6, a shifting member 7 for driving the plurality of blades 6 to swing synchronously is movably provided on the bellows 5, and a shifting unit for driving the shifting member 7 and the guide rod 35 to maintain transmission is movably provided on the box seat 2.

[0073] Specifically, Figure 5 , Figure 7 and Fig.11 As shown, an inner plate 51 is provided in the bellows 5, and a plurality of air ducts 52 are provided on the air duct 52. A plurality of blades 6 are respectively hingedly provided on the bellows 5 in a linear array, and the plurality of blades 6 are respectively located on one side of the air outlet of the air duct 52. The plurality of blades 6 are synchronously turned over so that the blast air flowing along the air duct 52 is guided by the blades 6 to blow toward the bumper on the driving roller 4 for cooling. The toggle unit movably provided on the box seat 2 is used to keep the toggle member 7 and the guide rod 35 in transmission, and then when the guide rod 35 moves up and down in the vertical direction, the toggle unit drives the toggle member 7 to swing, and then when the toggle member 7 swings, at this time, as shown in FIG. Fig.11 As shown, by utilizing the lever 7 to simultaneously drive multiple blades 6 to swing, thereby moving the bumper on the driving roller 4, the multiple blades 6 are swung so that the air can follow the moving path of the bumper, and the bumper is continuously blown, thereby extending the blowing time of the bumper and the blowing effect.

[0074] Furthermore, the shifting unit may be a connecting rod; or a gear and a connecting rod; or any other method known to those skilled in the art to maintain transmission between the shifting member 7 and the guide rod 35.

[0075] As another embodiment further provided by the present invention, the toggle unit includes a sliding rod 38 that is slidably arranged, a first power rod 37 is hingedly arranged on a mounting seat 36 that is fixedly installed on the top of the guide rod 35, and a first end of the first power rod 37 is hingedly arranged on the sliding rod 38, and a trigger rod 39 that drives the toggle member 7 to move is fixedly installed on the sliding rod 38.

[0076] Specifically, Figure 7 and Fig. 9 As shown, the dial member 7 is provided with an extension rod 71 , and a vertical slot 72 is opened on the extension rod 71 . Meanwhile, the slide rod 38 is slidably disposed on the outer wall of one side of the bracket 21 , and the trigger rod 39 is movably disposed in the vertical slot 72 .

[0077] Furthermore, when the injection molding is completed and the movable mold table 1 is away from the fixed mold table, the push plate 12 is disengaged from the push on the flap 8 and the impact block 32, and then the first torsion spring 99 is used to reset the flap 8 and flip it up. At the same time, the other limit plate 11 moves with the push plate 12 to move away from the box seat 2. At this time, the other limit plate 11 pushes the second end of the second reversing rod 95 to make the second reversing rod 95 flip again. At the same time, the movable shaft 96 slides again in the transverse groove 92 to make the reversing spring 94 accumulate force again, and then the reversing spring 94 accumulates force to the maximum value again and is accompanied by another limit plate 11 pushing the second end of the second reversing rod 95, so that the reversing spring 94 begins to release the accumulated force and push the second reversing rod 95 to flip quickly. At this time, the second reversing rod 95 cooperates with the reversing connecting rod 97 again to pull the knocking rod 98 to slide. At this time, the knocking rod 98 quickly moves away from the second end of the force-bearing rod 89, and then cooperates with the second torsion spring 82 to drive the stripping plate 83 to flip to approach the stop table 81. Then, along with the upward flipping of the flap 8, the sponge push pad 84 provided at the end of the stripping plate 83 moves to the bottom of the mold platform on the movable mold platform 1, so as to push the plastic bumper molded on the mold platform to strip the material. At the same time, because the push plate 12 is separated from the push of the impact block 32, the reset spring 34 releases the stored force to push the piston plate 3 to slide downward. At this time, multiple one-way air valves 26 are closed, so that the external air enters the piston cavity along the air inlet 25. At this time, the piston plate 3 moves slowly downward. When the piston plate 3 moves downward, the piston plate 3 cooperates with the stripping rod 47 to pull the main rack 46 to move. At this time, the main rack 46 slides on the auxiliary plate 27 and the main rack 46 and the main gear 45 are meshed. At this time, the main shaft 44 rotates to drive the large gear 43 to rotate, and then the large gear 43 and the force-bearing gear 42 are meshed to rotate one of the drive rollers 4. When one of the drive rollers 4 rotates, the belt transmission is transmitted between each two adjacent double-track pulleys 41, such as Figure 4As shown, the plurality of driving rollers 4 rotate synchronously, and then when the stripper plate 83 removes the plastic bumper molded on the die table to the driving roller 4, the plurality of driving rollers 4 rotate to move the bumper thereon.

[0078] Furthermore, as the piston plate 3 slides downward, Fig. 9 As shown, the mounting seat 36 at the top of the guide rod 35 cooperates with the first power rod 37 to pull the slide rod 38 to slide on the outer wall of one side of the bracket 21. When the slide rod 38 slides, the trigger rod 39 is movably set in the vertical groove 72, as shown in FIG. Figure 7 and Fig.11 As shown, when the trigger rod 39 moves in the vertical slot 72 to turn the dial 7, the dial 7 turns the plurality of blades 6 at the same time, and the guide rod 35 drops to drive the roller 4 to rotate to transport the bumper. The plurality of blades 6 are turned over so that the blast air flowing through the air duct 52 is guided by the blades 6 to blow toward the bumper on the driving roller 4 to cool it down. The blades 6 swing so that the blast air can be focused more on the bumper.

[0079] As an optimal embodiment further provided by the present invention, a wind plate 67 is symmetrically hingedly provided in the air duct 52, and an adjustment plate 64 is hingedly provided on the inner wall of one side of the air duct 52. The blade 6 drives the adjustment plate 64 to keep flipping synchronously through the connecting rod assembly arranged thereon, and the adjustment plate 64 flips and moves the wind plate 67 to adjust the wind direction.

[0080] Specifically, Figure 7 and Fig.11 As shown, a synchronization rod 68 is respectively arranged between the two wind plates 67, and the two ends of the synchronization rod 68 are respectively hingedly arranged on the two wind plates 67, and a rebound spring 66 is fixedly installed on the outer wall of one side of one wind plate 67, and the first end of the rebound spring 66 is fixedly installed on the inner wall of one side of the air duct 52. The connecting rod assembly includes a first connecting rod 62 and a second connecting rod 63, the first end of the first connecting rod 62 is hingedly arranged on the blade 6, and the second end of the first connecting rod 62 is hingedly arranged on the first end of the second connecting rod 63, and the second end of the second connecting rod 63 is provided with a side rod 69, and the side rod 69 is movably arranged in the waist groove 65 opened on the adjustment plate 64.

[0081] When the movable mold table 1 approaches the fixed mold table for automobile bumper injection molding, the push plate 12 moves with the movable mold table 1, and then uses the push plate 12 to approach the flap 8. When the push plate 12 pushes the flip plate 8 to make the flip plate 8 flip down, one of the limit plates 11 is used to push the second end of the second reversing rod 95. When the second reversing rod 95 flips over, the movable shaft 96 is movably set in the transverse groove 92 and pushes the pad 93. At the same time, the pad 93 squeezes the reversing spring 94 to make the reversing spring 94 accumulate force. As the second reversing rod 95 flips over, the reversing spring 94 accumulates force to the maximum value. Then, when one of the limit plates 11 continues to push the second end of the second reversing rod 95, the reversing spring 94 releases the accumulated force to push the pad 93, and then pushes the movable shaft 96 through the pad 93 to quickly flip the second reversing rod 95. Fig.12 As shown in FIG. 1 , when the reversing spring 94 pushes the second reversing rod 95 to flip, the movable shaft 96 cooperates with the reversing connecting rod 97 to push the knocking rod 98 to slide, and then the knocking rod 98 hits the second end of the force-bearing rod 89. When the knocking rod 98 hits the second end of the force-bearing rod 89, Figure 3 As shown, the force rod 89 turns over to cooperate with the movable rod 88 to pull the driving block 87 to slide away from the stripping plate 83. At this time, the driving block 87 cooperates with the pull rod 86 to pull the stripping plate 83 to turn close to the flap 8, thereby preventing the stripping plate 83 from affecting the injection molding of the movable mold table 1. At the same time, as the push plate 12 slides toward the side of the box seat 2, the end of the push plate 12 hits the impact block 32. When the impact block 32 is hit and slides, the impact block 32 cooperates with the connecting rod 31 to push the piston plate 3 to slide upward. At the same time, when the piston plate 3 slides, multiple one-way air valves 26 are opened to allow the gas in the piston cavity to be discharged through the one-way air valve 26 and the air inlet 25, and the return spring 34 is squeezed and stored.

[0082] Furthermore, when the piston plate 3 slides upward, as shown in FIG. Fig. 9 As shown, by using the mounting seat 36 to cooperate with the first power rod 37 to push the slide rod 38 to slide on the outer wall of one side of the bracket 21, at this time, the trigger rod 39 is movably set in the vertical groove 72, as shown in FIG. Figure 7 and Fig.11 As shown, when the trigger rod 39 moves in the vertical slot 72 to shift the shifting member 7, the shifting member 7 simultaneously shifts the plurality of blades 6 to flip, thereby causing the plurality of blades 6 to flip to be in a vertical state.

[0083] When the injection molding is completed and the movable mold table 1 is away from the fixed mold table, the push plate 12 is separated from the push of the flap plate 8 and the impact block 32, and then the first torsion spring 99 is used to reset the flap 8 and flip it up. At the same time, the other limit plate 11 moves with the push plate 12 to move away from the box seat 2. At this time, the other limit plate 11 pushes the second end of the second reversing rod 95 to make the second reversing rod 95 flip again. At the same time, the movable shaft 96 slides in the transverse groove 92 again to make the reversing spring 94 accumulate force again, and then the reversing spring 94 accumulates force to the maximum value again and is accompanied by another limit plate 11 pushing the second end of the second reversing rod 95, so that the reversing spring 94 begins to release the accumulated force and push the second reversing rod 95 to flip quickly. At this time, the second reversing rod 95 cooperates with the reversing connecting rod 97 again to pull the knocking rod 98 to slide. At this time, the knocking rod 98 quickly moves away from the second end of the force-bearing rod 89, and then cooperates with the second torsion spring 82 to drive the stripping plate 83 to flip to approach the stop table 81.

[0084] Then, along with the upward flipping of the flap 8, the sponge push pad 84 provided at the end of the stripping plate 83 moves to the bottom of the mold platform on the movable mold platform 1, so as to push the plastic bumper molded on the mold platform to strip the material. At the same time, because the push plate 12 is separated from the push of the impact block 32, the reset spring 34 releases the stored force to push the piston plate 3 to slide downward. At this time, multiple one-way air valves 26 are closed, so that the external air enters the piston cavity along the air inlet 25. At this time, the piston plate 3 moves slowly downward. When the piston plate 3 moves downward, the piston plate 3 cooperates with the stripping rod 47 to pull the main rack 46 to move. At this time, the main rack 46 slides on the auxiliary plate 27 and the main rack 46 and the main gear 45 are meshed. At this time, the main shaft 44 rotates to drive the large gear 43 to rotate, and then the large gear 43 and the force-bearing gear 42 are meshed to rotate one of the drive rollers 4. When one of the drive rollers 4 rotates, the belt transmission is transmitted between each two adjacent double-track pulleys 41, such as Figure 4 As shown, the multiple driving rollers 4 rotate synchronously, and then when the stripping plate 83 removes the plastic bumper injection-molded on the mold platform to the driving rollers 4, the multiple driving rollers 4 rotate to move and transport the bumper thereon.

[0085] Furthermore, as the piston plate 3 slides downward, Fig. 9 As shown, the mounting seat 36 at the top of the guide rod 35 cooperates with the first power rod 37 to pull the slide rod 38 to slide on the outer wall of one side of the bracket 21. When the slide rod 38 slides, the trigger rod 39 is again movably set in the vertical groove 72, as shown in FIG. Figure 7 and Fig.11As shown, when the trigger rod 39 moves in the vertical slot 72 to turn the dial 7, the dial 7 turns the plurality of blades 6 at the same time, and the guide rod 35 drops to drive the roller 4 to rotate to transport the bumper. The plurality of blades 6 are turned over so that the blast air flowing through the air duct 52 is guided by the blades 6 to blow toward the bumper on the driving roller 4 to cool it down. The blades 6 swing so that the blast air can be focused more on the bumper.

[0086] Furthermore, when the blade 6 is turned over, the blade 6 pulls the plurality of first connecting rods 62, and the first connecting rods 62 are used to pull the second connecting rods 63 upward. When the second connecting rods 63 move upward, the side rods 69 on the second connecting rods 63 move in the waist groove 65. Figure 7 As shown, the second connecting rod 63 is moved upward to flip the adjusting plate 64, and then the wind plate 67 is flipped by one end of the adjusting plate 64, and the two wind plates 67 are kept flipped synchronously by the synchronization rod 68, and then the synchronous flipping of the two wind plates 67 is used to make the plastic bumper dissipate heat more comprehensively through the blowing swing in the air duct 52. The rebound spring 66 is used to reset the two wind plates 67 when they stop being pushed by the adjusting plate 64.

[0087] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
