Description

Technical Field

[0001] This invention relates to the field of foam packaging box manufacturing technology, and more specifically, to a rapid solidification mold for foam packaging box production. Background Technology

[0002] The rapid solidification mold for foam packaging box production is a type of mold that, after the mold is closed, saturated steam is introduced into the mold cavity to cause the foam particles to foam and melt instantly. Then the mold is opened, and after the formed foam packaging box cools down and solidifies, the foam box is rapidly solidified.

[0003] After the foam is molded, the molded foam packaging box needs to be removed from the mold. Because the foam packaging box is soft and expands during the molding process, it adheres tightly to the inner wall of the mold, creating negative pressure at the moment of removal, making it difficult for the box to detach from the mold cavity. Forcibly ejecting or quickly pulling it out can easily cause the foam packaging box to tear or break. While a slow demolding method allows air to gradually enter the mold and reduce the internal negative pressure, it requires more demolding time, thus reducing the overall molding efficiency of the foam packaging box. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a rapid solidification mold for the production of foam packaging boxes, so as to solve the problem that negative pressure is generated at the moment the foam packaging box is taken out, making it difficult for the box to detach from the mold cavity.

[0005] To solve the above problems, the present invention adopts the following technical solution: A rapid solidification mold for producing foam packaging boxes includes a mold cover plate, a forming mold, a mold filling plate, and injection ports. The mold cover plate is rotatably connected to the top of the forming mold via a hinge. Multiple injection ports are connected to the upper surface of the mold cover plate. The front ends of the forming mold and the mold cover plate are fixedly connected with mutually cooperating latches. The mold cover plate also includes a release auxiliary mechanism located on both sides of the forming mold. The release auxiliary mechanism includes multiple blocking tubes located inside both sides of the forming mold. Each blocking tube has an air outlet on both sides. An air inlet pipe is connected to the surface of the blocking tube. The end of the air inlet pipe away from the blocking tube is connected to an air management pipe. The cross-sectional shape of the air management pipe is an inverted "T" shape. A second piston plate is provided inside the longitudinal arm end of the air management pipe.

[0006] Furthermore, a second upper push rod is fixedly connected to the upper surface of the second piston plate, and multiple connecting blocks are fixedly connected to both sides of the mold cover plate. A first lower pressure rod is fixedly connected to the lower surface of the connecting block. The first lower pressure rod is located directly above the second upper push rod. A first spring is fixedly connected to the interior of the air management pipe at the end away from the air intake pipe. A first piston plate is fixedly connected to the surface of the first spring. The first piston plate and the second piston plate together form a piston structure with the interior of the air management pipe.

[0007] Furthermore, a sealing plate is inserted inside the air management pipe near the molding die. A second spring is fixedly connected to the top of the sealing plate, and the bottom of the second spring is fixedly connected to the air management pipe. A first upper push rod is fixedly connected to the top of the sealing plate.

[0008] Furthermore, a second pressing rod is fixedly connected to the lower surface of the connecting block, and the second pressing rod is located directly above the first upper pushing rod.

[0009] Furthermore, the second pressing rod and the first pushing rod are each fixedly connected to a magnet at their respective ends, and the two magnets are opposite poles on their respective sides. A sealing ring is fixedly connected inside the air management pipe, and a lifting connecting rod is fixedly fitted on the surface of each of the multiple air intake pipes.

[0010] Furthermore, a rotating shaft is fixedly connected to both sides of the rear end of the mold cover plate, and a rotating frame is rotatably connected to the surface of the rotating shaft. A fixed block is fixedly connected to both sides of the forming mold, and a guide frame is fixedly connected to both sides of the forming mold. A lifting frame is provided on the surface of the guide frame, and a sliding groove is opened on the surface of the lifting frame. The guide frame is slidably inserted into the interior of the sliding groove. A lifting rod is fixedly connected to the top of the fixed block, and the lifting rod is inserted into the interior of the fixed block. A crossbar is fixedly connected to the top of the lifting rod, and two actuating rods are fixedly connected to the arc segment of the rotating frame.

[0011] Furthermore, the fixed block has a double spherical groove inside, and a ball is disposed inside the double spherical groove. The lifting rod is fixedly inserted into the inside of the ball. Two locking blocks are slidably connected inside the fixed block. A third spring is fixedly connected inside the fixed block. The two third springs are respectively fixedly connected to the two locking blocks.

[0012] Furthermore, it also includes an ejection mechanism, which is disposed at the bottom of the molding die. The ejection mechanism includes a cylinder disposed at the bottom of the molding die, a connecting block disposed inside the cylinder, an upper pusher fixedly connected to the upper surface of the connecting block, and the top end of the upper pusher fixedly connected to the lower surface of the mold filling plate.

[0013] Furthermore, a lower pressure strip is fixedly connected to both front ends of the mold cover plate, a connecting frame is fixedly connected to the upper end of the upper push column, a fourth spring is fixedly connected to the lower surface of the connecting block, and the bottom end of the fourth spring is fixedly connected to the inner bottom end of the cylinder.

[0014] Furthermore, the surface of the upper push column is provided with a deceleration groove, and four guide brackets are fixedly connected to the top of the cylinder. The four guide brackets are in pairs. The horizontal arm ends of the guide brackets are slidably fitted with push frames. A fifth spring is fixedly connected between the two horizontal arm ends of the upper ends of the two push frames. A sleeve and a sleeve block are fixedly connected to the two horizontal arm ends of the lower ends of the two push frames respectively. The sleeve block is slidably fitted inside the sleeve. A separation roller is rotatably connected between the two sleeve blocks and the two sleeves. The two separation rollers are located inside the deceleration groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) In this scheme, during the opening of the mold cover, the blocking pipe is moved to the air outlet and exposed inside the molding mold, which can push open the two sides of the foam packaging box and the two inner walls of the molding mold. This allows air to pass through the air inlet pipe into the blocking pipe and enter the interior of the molding mold through the air outlet, reducing the suction force generated by the negative pressure when the foam packaging box is demolded, reducing the demolding difficulty of the foam packaging box and reducing the probability of damage during the demolding process.

[0016] (2) When using the mold to produce foam packaging boxes, the mold cover is closed, the first pressing rod is pressed on the second upper pushing rod, and air is injected into the air management pipe. When the sealing plate is opened, the first spring pushes the first piston plate to inject air into the molding mold, so that the side wall of the foam packaging box is separated from the inner side wall of the molding mold more thoroughly, further reducing the suction force generated by the negative pressure when the foam packaging box is demolded, reducing the demolding difficulty of the foam packaging box and reducing the probability of breakage during the demolding process of the foam packaging box.

[0017] (3) After the foam packaging box is formed, the mold cover is opened and the fourth spring pushes the upper push column to move upward, which can push the foam packaging box to move upward, thereby assisting the foam packaging box to be demolded, so as to prevent the foam packaging box from being completely embedded in the molding mold during the demolding process and difficult to remove, resulting in the foam packaging box being difficult to demold and easily damaged during the demolding process.

[0018] (4) Since the deceleration groove is wide at the top and narrow at the bottom, the two separation rollers are squeezed and the two fifth springs are in a stretched state during the upward movement of the push column. Therefore, it can provide resistance to slow down the movement speed of the push column, provide sufficient cooling time for the foam packaging box, and reduce the impact force on the foam packaging box when it is pushed upward. This prevents the foam packaging box from being pushed away from the molding mold due to a large impact before it has fully cooled and solidified, which would cause the foam packaging box to deform or break.

[0021] 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.

[0022] Please see Figure 1-6 A quick-setting mold for producing foam packaging boxes includes a mold cover plate 1, a forming mold 2, a mold filling plate 608, and injection ports 3. The mold cover plate 1 is rotatably connected to the top of the forming mold 2 via a hinge. Multiple injection ports 3 are connected to the upper surface of the mold cover plate 1. The front ends of the forming mold 2 and the mold cover plate 1 are fixedly connected with mutually cooperating latches 4. The mold also includes a release auxiliary mechanism, which is disposed on both sides of the forming mold 2.

[0023] The disengagement auxiliary mechanism includes multiple blocking pipes 506 disposed inside both sides of the molding die 2. Each blocking pipe 506 has an air outlet 507 on both sides. An air inlet pipe 508 is connected to the surface of the blocking pipe 506. An air management pipe 513 is connected to the end of the air inlet pipe 508 away from the blocking pipe 506. The cross-sectional shape of the air management pipe 513 is an inverted "T" shape. A second piston plate 516 is disposed inside the longitudinal arm end of the air management pipe 513.

[0024] The upper surface of the second piston plate 516 is fixedly connected to a second upper push rod 511. Multiple connecting blocks 503 are fixedly connected to both sides of the mold cover plate 1. A first lower pressure rod 504 is fixedly connected to the lower surface of each connecting block 503, and the first lower pressure rod 504 is located directly above the second upper push rod 511. A first spring 514 is fixedly connected inside the end of the air management pipe 513 away from the air intake pipe 508. A first piston plate 515 is fixedly connected to the surface of the first spring 514. Both the first piston plate 515 and the second piston plate 516 form a piston structure with the interior of the air management pipe 513. A sealing plate 512 is inserted inside the air management duct 513 near the molding die 2. A second spring 517 is fixedly connected to the top of the sealing plate 512, and the bottom of the second spring 517 is fixedly connected to the air management duct 513. A first upper push rod 510 is fixedly connected to the top of the sealing plate 512, and a second lower pressure rod 505 is fixedly connected to the lower surface of the connecting block 503. The second lower pressure rod 505 is located directly above the first upper push rod 510. Because the vertical stroke of the first upper push rod 510 is short, the two magnets 509 can accurately touch each other without misalignment when the second lower pressure rod 505 moves downward. Magnets 509 are fixedly connected to the ends of the second lower pressure rod 505 and the first upper push rod 510 that are close to each other, and the sides of the two magnets 509 that are close to each other are opposite poles. A sealing ring 518 is fixedly connected inside the air management duct 513, and a lifting connecting rod 501 is fixedly sleeved on the surface of each of the multiple air inlet pipes 508.

[0025] The mold cover plate 1 has two fixedly connected rotating shafts 519 on both rear ends. A rotating frame 502 is rotatably connected to the surface of each rotating shaft 519. The forming mold 2 has two fixedly connected fixed blocks 522 on both sides and two fixedly connected guide frames 523 on both sides. A lifting frame 530 is provided on the surface of the guide frame 523, and a sliding groove 529 is formed on the surface of the lifting frame 530. The guide frame 523 is slidably inserted into the sliding groove 529. A lifting rod 521 is fixedly connected to the top of each fixed block 522, and the lifting rod 521 is inserted into the interior of the fixed block 522. A crossbar 524 is fixedly connected to the top of the lifting rod 521. Two actuating rods 520 are fixedly connected to the arc segment of the rotating frame 502.

[0026] The fixed block 522 has a double spherical groove 525 inside, and a sphere 527 is disposed inside the double spherical groove 525. The lifting rod 521 is fixedly inserted into the sphere 527. Two locking blocks 528 are slidably connected inside the fixed block 522, and a third spring 526 is fixedly connected inside the fixed block 522. The two third springs 526 are respectively fixedly connected to the two locking blocks 528.

[0027] By adopting the above technical solution, when it is necessary to use a mold for rapid molding of foam packaging boxes, the mold cover plate 1 is placed on the molding mold 2, and the mold cover plate 1 is fixed on the molding mold 2 by the locking buckle 4. Then, the raw material is injected into the molding mold 2 through the injection port 3. After the raw material is molded and cooled, the mold cover plate 1 is opened. During the opening process of the mold cover plate 1, as the mold cover plate 1 rotates upward, the rotating shaft 519 and the rotating frame 502 can be driven to rotate upward simultaneously, and the actuating rod 520 located below is driven to rotate upward to lift the crossbar 524. The lifting rod 521 and the lifting frame 530 also move upward accordingly. As the lifting frame 530 moves upward, its lower inclined surface contacts and presses against the lifting rod 501, causing the lifting rod 501 to move closer to the molding mold 2. This simultaneously drives multiple air inlet pipes 508 to insert into the molding mold 2, moving the blocking pipe 506 until it is slightly inserted into the molding mold 2, exposing the air outlet 507 inside the molding mold 2. This pushes open the sides of the foam packaging box from the two inner walls of the molding mold 2. Air can then pass through the air inlet pipes 508 into the blocking pipes 506 and into the molding mold 2 through the air outlet 507. This reduces the suction force generated by the negative pressure during foam packaging box demolding, lowering the demolding difficulty and reducing the probability of breakage during demolding.

[0028] As the lifting rod 521 moves upward, it simultaneously drives the ball 527 upward, causing the ball 527 to compress the locking block 528, separating the two locking blocks 528 in a direction away from each other. At this time, the third spring 526 is in a compressed state. Until the ball 527 moves above the double spherical groove 525, the third spring 526 pushes the two locking blocks 528 back into place below the ball 527. The ball 527 can no longer move upward or downward, thus limiting the upper limit of the movement of the fixed block 522. This prevents the mold cover plate 1 from opening too wide, which could cause the blocking tube 506 to be inserted too deeply, resulting in excessive pressure damage to the foam packaging box and making it difficult to demold the foam packaging box. Furthermore, during this process, the ball 527, stuck in the double spherical groove 525, cannot move up or down, ensuring that the sides of the foam packaging box remain open for subsequent demolding operations. When demolding is completed and the next foam packaging box forming operation is carried out, the mold cover plate 1 is put back on, and the rotating frame 502 rotates downward to make the upper toggle lever 520 press down the crossbar 524, so that the ball 527 moves downward and squeezes open the two clips 528, and the ball 527 moves to the bottom of the double spherical groove 525.

[0029] During the opening of the mold cover plate 1, the first pressing rod 504 and the second pressing rod 505 move upward simultaneously. As the second pressing rod 505 moves upward, the attraction between the two magnets 509 drives the first pushing rod 510 upward, which in turn pulls the sealing plate 512 upward, opening the air management pipe 513. At this time, the second spring 517 is in a stretched state. When the second spring 517 is stretched to its limit, the tension on the two magnets 509 exceeds the upper limit of the magnetic attraction force, causing the two magnets 509 to separate. Simultaneously, the second spring 517 pulls the sealing plate 512 back into the air management pipe 513, preparing for the next air storage operation.

[0030] When producing foam packaging boxes using a mold, the second upper push rod 511 and the second piston plate 516 are first lifted, followed by the mold cover plate 1 being closed, and the first lower pressure rod 504 moving downwards accordingly. Because the upper and lower stroke of the second upper push rod 511 is short, the first lower pressure rod 504 can accurately press against the second upper push rod 511 without misalignment, causing the second upper push rod 511 and the second piston plate 516 to move downwards, injecting air into the air management pipe 513. This causes the first piston plate 515 to move away from the sealing plate 512, at which point the first spring 514 is compressed. When the sealing plate 512 is opened, the first spring 514 pushes the first piston plate 515 to inject air into the molding mold 2, making the side wall of the foam packaging box more thoroughly separate from the inner side wall of the molding mold 2. This further reduces the suction force generated by the negative pressure during demolding of the foam packaging box, reducing the difficulty of demolding and the probability of breakage during demolding.

[0031] like Figure 7-9 As shown, it also includes an ejection mechanism, which is disposed at the bottom of the molding mold 2. The ejection mechanism includes a cylinder 603 disposed at the bottom of the molding mold 2. A connecting block 604 is disposed inside the cylinder 603. An upper pusher 605 is fixedly connected to the upper surface of the connecting block 604. The top end of the upper pusher 605 is fixedly connected to the lower surface of the mold filling plate 608. Lower pressure strips 602 are fixedly connected to the front ends of both sides of the mold cover plate 1. A connecting frame 601 is fixedly connected to the upper end of the upper pusher 605. A fourth spring 606 is fixedly connected to the lower surface of the connecting block 604. The bottom end of the fourth spring 606 is fixedly connected to the inner bottom end of the cylinder 603.

[0032] The upper push column 605 has a deceleration groove 607 on its surface. The top of the cylinder 603 is fixedly connected to four guide brackets 610, which are arranged in pairs. The horizontal arm ends of the guide brackets 610 are slidably fitted with push frames 609. A fifth spring 611 is fixedly connected between the two horizontal arm ends of the two push frames 609. The two horizontal arm ends of the two push frames 609 are respectively fixedly connected to a sleeve 612 and a sleeve block 613 at their lower ends. The sleeve block 613 is slidably fitted inside the sleeve 612. A separation roller 614 is rotatably connected between the two sleeve blocks 613 and the two sleeves 612. The two separation rollers 614 are located inside the deceleration groove 607.

[0033] By adopting the above technical solution, the cylinder 603 is installed on the workbench, and the molding mold 2 is also installed on the workbench. After the foam packaging box is formed, the mold cover plate 1 is opened, so that the lower pressure strip 602 is disengaged from the connecting frame 601. At this time, the fourth spring 606, which is in a compressed state, pushes the upper push column 605 upward, so that the mold filling plate 608 is disengaged from the molding mold 2 and pushes the foam packaging box upward, thereby assisting the demolding of the foam packaging box. This prevents the foam packaging box from being completely embedded in the molding mold 2 during the demolding process, making it difficult to remove and causing the foam packaging box to be difficult to demold and prone to breakage during the demolding process.

[0034] Because the deceleration groove 607 has a structure that is wider at the top and narrower at the bottom, during the upward movement of the push column 605, the two separating rollers 614 are compressed and move towards each other, causing the two fifth springs 611 to be in a stretched state. Therefore, the separating rollers 614 abut against the inner wall of the deceleration groove 607 to provide resistance and slow down the movement speed of the push column 605, providing sufficient cooling time for the foam packaging box and reducing the impact force on the foam packaging box when it is pushed upward, preventing the foam packaging box from being pushed away from the molding mold 2 by a large impact before it has completely cooled and solidified, which would cause the foam packaging box to deform or break.

[0035] Instructions for use: First, place the mold cover plate 1 on the forming mold 2; At the same time, the first pressing rod 504 presses on the second pushing rod 511, injecting air into the air management pipe 513; Subsequently, the mold cover plate 1 is fixed to the forming mold 2 by the locking buckle 4; Subsequently, the raw material is injected into the molding mold 2 through the injection port 3; Next, open mold cover plate 1; At the same time, the blocking tube 506 moves to be slightly inserted into the interior of the molding die 2; At the same time, air is injected into the molding die 2; Finally, the fourth spring 606 pushes the mold filling plate 608 to detach from the molding mold 2, assisting in the demolding of the foam packaging box.

[0036] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
