Description

Technical Field

[0001] The present invention relates to the technical field of luggage molding, and specifically relates to a plastic suction molding device for processing luggage of a rolling suitcase. Background Art

[0002] A rolling suitcase refers to a luggage with a handle and wheels, which is widely used because of its convenience. During the production process of a rolling suitcase, PC and ABS materials are usually adsorbed on the outer surface of the box body to increase the beauty and wear resistance of the box. The above production often uses a plastic suction molding machine. The process of this molding equipment mainly uses the vacuum suction generated by a vacuum pump to suck the heated and softened thermoplastic sheets such as PVC, PET, PETG, PTT, PP, PE, and PS through a mold into various shaped vacuum covers, or attach them to the surface of various shaped products. Before plastic suction molding, a mold release agent is usually sprayed on the surface of the mold. The main function of the mold release agent is to reduce the adhesion between the mold and the plastic, prevent the molded plastic part from adhering to the mold, so as to facilitate demolding and improve production efficiency.

[0003] In the prior art, several groups of alternately arranged grooves and protrusions are commonly provided on the surface of a rolling suitcase to increase the moment of inertia of the material, thereby improving the compressive strength of the box body. However, during the spraying process, this design may cause the spraying agent to be unevenly distributed. The thickness of the sprayed coating on the protruding part is relatively larger than that on the sunken part, and the sunken part will accumulate the coating agent because it is lower than the protruding part; moreover, an installation groove for installing wheels is provided on one side of the rolling suitcase. After the mold release agent is sprayed, there is a lack of a more effective structure to scrape and level the mold release agent on its surface. Summary of the Invention

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1, please refer to Figures 1 to 13 , the present invention discloses a plastic suction molding device for processing luggage of a suitcase, including a bench 1 and a limit frame 2 arranged on the bench 1. An electric push rod 4 for driving the forming die to lift is installed at the central position inside the bench 1, and a lifting table 3 for fixing the die is provided at the output rod end of the electric push rod 4.

[0037] In this embodiment, a bench 1 and an electric push rod 4 arranged inside the bench 1 are provided. The telescopic rod end of the electric push rod 4 is provided with a lifting table 3. The die is placed on the lifting table 3, and a limit frame 2 is arranged at the top of the bench 1. The plastic suction film is pressed by the limit frame 2, and the thermoplastic parison is closely attached to the inner wall of the die through compressed air, and a hollow product is formed after cooling.

[0038] A spraying assembly for spraying a coating agent on the die is arranged on one side inside the bench 1. The spraying assembly is movably arranged inside the bench 1 through two electric slide tables 18 connected to the inside of the bench 1. The spraying assembly includes a moving frame 5. The moving frame 5 is arranged in an L-shaped structure. A first nozzle 6 is arranged inside the moving frame 5. A first scraper 7 is arranged on one side of the first nozzle 6. The side of the first scraper 7 in contact with the die is provided with a groove and a convex structure matching the surface of the die. The outer wall of the first scraper 7 is connected to the electric slide table 18.

[0039] In this embodiment, two sets of electric sliding tables 18 are symmetrically arranged in the bench 1. A moving frame 5 is connected to one side of the electric sliding table 18. A first nozzle 6 and a first squeegee 7 are respectively arranged in the moving frame 5. The first nozzle 6 is arranged at the front end in the moving direction of the moving frame 5, and the first squeegee 7 is arranged behind the first nozzle 6. The electric sliding table 18 is started to drive the moving frame 5 and the first nozzle 6 and the first squeegee 7 in the moving frame 5 to move in the bench 1. A groove and a convex structure matching the surface of the mold are formed inside the first squeegee 7. When the first squeegee 7 moves to the surface of the mold, the first squeegee 7 fits and matches the mold, and the release agent sprayed on the surface of the mold by the first nozzle 6 is evenly scraped. Setting two sets of first squeegees 7 can complete the even scraping treatment of the upper surface and both side surfaces of the mold, so as to ensure the uniform adhesion of the release agent and avoid uneven thickness of the sprayed release agent, which affects the demoulding effect.

[0040] Embodiment 2 is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 13 , the spraying assembly further includes a second support shaft 29 and a third support shaft 39 symmetrically arranged on both sides of the bench 1. Second nozzles 20 are arranged at the tops of the second support shaft 29 and the third support shaft 39.

[0041] In this embodiment, two sets of second nozzles 20 are symmetrically arranged on the front side and the rear side of the mold respectively. The second nozzles 20 are respectively rotatably connected to the bench 1 through the second support shaft 29 and the third support shaft 39 to realize the spraying of the release agent on the front side and the rear side of the mold.

[0042] Furthermore, a first bracket 12 is arranged on one side of the bench 1. The second support shaft 29 is rotatably connected to the first bracket 12. A second gear 22 is arranged on the surface of the second support shaft 29. A second rack 23 is meshed with one side of the second gear 22. The second rack 23 is slidably connected to the bench 1. One end of the second rack 23 is connected to a lever 21 through a first support shaft 27. The lever 21 extends to one side of the first squeegee 7. The first support shaft 27 is connected to the second rack 23 through a torsion spring 28;

[0043] In this embodiment, a first bracket 12 is arranged in the bench 1 to support the second support shaft 29, so that the second nozzle 20 can rotate, thereby ensuring that the spraying range can meet the spraying requirements of the release agent.

[0044] Specifically, a second gear 22 is provided on the surface of the second support shaft 29. A second rack 23 is engaged with one side of the second gear 22. One end of the second rack 23 is connected to a first support shaft 27 through a torsion spring 28. The first support shaft 27 is fixedly connected to the lever 21. When the first scraper 7 moves to one end of the lever 21, the second rack 23 is driven to move on the first bracket 12 through the lever 21, thereby driving the second gear 22 to rotate, thereby driving the second nozzle 20 to rotate, thereby expanding the spraying range of the second nozzle 20 and ensuring the spraying effect of the second nozzle 20 on the mold.

[0045] When the first support shaft 27 moves close to the mold, the torque of the torsion spring 28 pulled by the lever 21 reaches the limit, so that the angle between the lever 21 and the torsion spring 28 expands until the lever 21 is disengaged from the first scraper 7.

[0046] An elastic connection assembly is provided on one side of the second rack 23. The elastic connection assembly includes a limiting rod 24 connected to one end of the second rack 23. A limiting plate 25 is provided on one side of the second rack 23. A second spring 26 is connected between the limiting plate 25 and the limiting rod 24.

[0047] In this embodiment, a limiting rod 24 is connected to one end of the second rack 23, and a second spring 26 is connected between the limiting rod 24 and the limiting plate 25. When the first scraper 7 is disengaged from the lever 21, the second spring 26 is used to drive the second gear 22 to reset, thereby driving the second nozzle 20 to rotate again to complete the spraying of the front side of the mold.

[0048] Embodiment 3 is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 13 , a second bracket 40 is provided on one side of the bench 1. The third support shaft 39 is rotatably connected to the second bracket 40 through a torsion spring 28.

[0049] In this embodiment, a second bracket 40 is provided on the bench 1 close to the rear side of the mold, and a torsion spring 28 is also provided between the second bracket 40 and the third support shaft 39, which facilitates the rotation and reset of the second nozzle 20 and ensures the spraying range of the second nozzles 20 symmetrically arranged on the rear side of the mold.

[0050] Embodiment 4 is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 13, on the side of the bench 1 far from the spraying assembly, two sets of leveling assemblies are symmetrically arranged. The leveling assemblies can rotate in the installation grooves of the molds. The leveling assemblies include first rotating shafts 13 rotatably installed on both sides of the second bracket 40. The top ends of the first rotating shafts 13 are connected with second scraping plates 14. First gears 15 are arranged on the surfaces of the first rotating shafts 13. A top block 41 is arranged on the side of the bench 1 close to the first gears 15; one side of the moving frame 5 is connected with a support plate 9. One side of the support plate 9 is slidably connected with a first rack 8. Plug rods 10 are symmetrically arranged on one side of the first rack 8. The plug rods 10 are slidably connected with the support plate 9. A first spring 11 is connected between the support plate 9 and the first rack 8. The first spring 11 is sleeved outside the plug rods 10.

[0051] Based on the need to set depressions for the rollers on the rear side of the mold, therefore, a leveling structure needs to be set for the above depressions, specifically including a first rotating shaft 13, a second scraping plate 14, and a first disc 16 connected to the bottom of the second scraping plate 14. Among them, a first gear 15 is arranged on the surface of the first rotating shaft 13. A first rack 8 is arranged on one side of the moving frame 5. When the moving frame 5 moves to the position of the first rotating shaft 13, the first rack 8 meshes with the first gear 15. Thus, during the movement of the moving frame 5, the first rotating shaft 13 is driven to rotate, so that when the second scraping plate 14 fastens the depression, a leveling process is performed on it.

[0052] To avoid the interference of the setting of the first rack 8 on the movement of the moving frame 5, a support plate 9 and a first spring 11 connected between the support plate 9 and the first rack 8 are arranged between the first rack 8 and the moving frame 5. When the moving frame 5 moves to the top block 41, at this time the spraying is completed, the top block 41 pushes the plug rod 10, pushing the first rack 8 to extend and mesh with the first gear 15. As the moving frame 5 continues to move, the first rack 8 drives the first gear 15 to rotate, thereby driving the first rotating shaft 13 and the second scraping plate 14 to rotate and level in the depression.

[0053] Example Five. This example is an explanatory note based on Example One. Specifically, please refer to Figures 1 to 13 , a driving plate 31 is arranged at the bottom end of the first rotating shaft 13, and a dial plate 30 is arranged at the bottom end of the third support shaft 39. The driving plate 31 can dial the dial plate 30 to rotate when rotating.

[0054] In this factual example, by using the rotation of the first rotating shaft 13, the driving plate 31 at the bottom end of the first rotating shaft 13 is driven to rotate. After the driving plate 31 contacts the dial plate 30, the dial plate 30 is pushed to drive the third support shaft 39 to rotate, thereby driving the second nozzle 20 to rotate, ensuring the spraying effect of the second nozzle 20 on the rear side of the mold.

[0055] Example Six. This example is an explanatory note based on Example One. Specifically, please refer to Figures 1 to 13, the second squeegee 14 is arranged in a hollow plate structure. A first disc 16 is connected to the bottom of the second squeegee 14. A floating plate 17 is slidably connected to one side of the first disc 16. The floating plate 17 is arranged as an arc-shaped plate. Guide bars 35 are symmetrically connected to both sides of the floating plate 17. The guide bars 35 are slidably connected to the first disc 16. A third spring 34 is connected between the guide bars 35 and the first disc 16.

[0056] In this embodiment, for the structure of the recess, a first disc 16 is connected to one end of the second squeegee 14 to level the horizontal plane of the recess, and a elastically connected floating plate 17 is arranged on one side of the first disc 16 to level the vertical plane of the recess by using the floating plate 17.

[0057] Embodiment Seven. This embodiment is an explanatory description based on Embodiment One. Specifically, please refer to Figures 1 to 13 , a driving component for driving the floating plate 17 to float up and down is arranged in the first rotating shaft 13. The driving component includes a push plate 33 slidably connected in the second squeegee 14. A toothed plate 32 is arranged on the surface of the first rotating shaft 13. A third gear 42 is connected to the toothed plate 32. One side of the support plate 9 is connected to a third rack 43 through a sixth spring 45. The third rack 43 is arranged above the first rack 8; a fifth spring 44 is connected between the push plate 33 and the second squeegee 14. A convex block 36 is arranged on the inner wall of the floating plate 17, and a slope is arranged on one side of the convex block 36.

[0058] In this embodiment, a set of driving components capable of driving the floating plate 17 to float up and down is arranged in the first rotating shaft 13, specifically including a toothed plate 32, a push plate 33, a third gear 42 and a third rack 43. When the first rack 8 drives the first gear 15 to drive the first rotating shaft 13 to rotate, the third rack 43 simultaneously drives the third gear 42 to rotate, thereby driving the toothed plate 32 to rotate. Since the push plate 33 is slidably connected in the second squeegee 14, when the toothed plate 32 rotates, the push plate 33 is driven to reciprocate in the second squeegee 14 through the connection of the fifth spring 44 by using the concave and convex teeth. A convex block 36 is arranged on the inner wall of the floating plate 17, and a slope is arranged on one side of the convex block 36. The push plate 33 is used to reciprocally fit the slope surface of the convex block 36 to move horizontally, thereby driving the floating plate 17 to float up and down, improving the scraping and leveling treatment of the release agent on the vertical plane of the recess.

[0059] Embodiment Eight. This embodiment is an explanatory description based on Embodiment One. Specifically, please refer to Figures 1 to 13 , a push rod 38 is slidably connected in the second squeegee 14. The push rod 38 is arranged in contact with the convex block 36. A fourth spring 37 is connected between the push rod 38 and the inner wall of the second squeegee 14. One side of the moving frame 5 is connected to a corrugated plate 19.

[0060] In this embodiment, the driving assembly can also be sequentially arranged as the corrugated plate 19, the fourth spring 37, and the push rod 38. The corrugated plate 19 is arranged on one side of the electric slide table 18 close to the first disc 16. When the first disc 16 rotates, one end of the push rod 38 arranged in the first disc 16 is affected by the concave-convex structure arranged on the inner wall of the corrugated plate 19 and reciprocates horizontally in the second scraper 14. The other end of the push rod 38 pushes the convex block 36, thereby driving the floating plate 17 to float up and down, improving the scraping and leveling treatment of the release agent on the vertical surface of the recess.

[0061] It should be noted that in the specific implementation of the sixth and seventh embodiments, only one of them can be selected, and both can improve the scraping and leveling treatment of the release agent on the vertical surface of the recess.
