Description

Technical Field

[0001] The invention relates to the technical field of injection molding production of interior decoration parts, and more specifically to an injection molding mold for automobile interior decoration parts with an automatic cloth cutting function. Background Art

[0002] Automotive interior parts generally refer to car compartment partitions, door trim panels, instrument panel assemblies, armrests, carpets and other parts and materials. Automotive interior parts have little effect on the vehicle's operating performance, but their appearance is clear at a glance and represent the image of the entire vehicle. Automotive interior parts have to assume functions such as vibration reduction, heat insulation, sound absorption and sound insulation, which will directly affect the comfort of the vehicle.

[0003] When producing automotive interior parts, hot melt adhesive and coating materials need to be injection molded. The plastic parts and the skin are combined together inside the mold cavity. The environment will not be polluted during the molding process. The molded products have good adhesion and are not easy to fall off or crack. When automotive interior parts are produced using the low-pressure injection molding production process, the skin material needs to be embedded in the mold cavity, and then the hot melt is injected into the cavity so that the hot melt and the skin material are tightly combined in the cavity to form automotive interior parts;

[0004] When producing interior parts, the surface material needs to be cut first, that is, the cloth is cut into preset size specifications, and then it is placed in the mold for injection molding and hot pressing. After molding, it is taken out to complete the production. This process requires two steps, and both steps require a lot of manual assistance;

[0005] When cutting the surface material manually, more manpower is required. If automatic cutting is used, when the surface material is cut, if the surface material warps up after one cut, there will be problems with the cutting size during subsequent cutting, which will affect the size of the automotive interior parts.

[0016] Technical effects and advantages of the present invention:

[0017] The present invention can automatically cut cloth by cooperating between the cloth cutting upper mold and the processing lower mold. The cut epidermis material is placed in the processing lower mold. After the cloth is cut, the servo motor is started and drives the threaded rod to rotate. At this time, the moving plate drives the cloth cutting upper mold and the hot pressing upper mold to move. The hot pressing upper mold and the processing lower mold cooperate to perform injection molding and hot pressing molding. After the formation, the servo motor drives the cloth cutting upper mold and the hot pressing upper mold to reset, thereby realizing automatic cloth cutting and injection molding.

[0018] After the cloth cutting upper die of the present invention cuts the cloth, the blowing mechanism passes over the top of the processing lower die, the rotating motor in the blowing mechanism starts and drives the output gear to rotate through the rotating shaft, and when the output gear rotates, the output gear, the synchronous gear and the speed increasing gear are transmitted, and then the rotating blades rotate, and when the rotating blades rotate and pass over the top of the processing lower die, the rotating blades blow air downward to blow away impurities when the surface material is cut, and the blown surface material is leveled, thereby improving the quality after injection molding;

[0019] The surface material of the present invention is placed on a work base. When cutting the cloth, the cloth cutting upper mold will move downward. When the cloth cutting upper mold moves downward, it drives the connecting card slot to move downward through the connecting plate. When the connecting card slot moves downward, it drives the slider to move through the limiting groove. At this time, the slider drives the sliding rod to move downward. After the sliding rod moves vertically downward to the bottom of the lower pressing block and contacts the surface material, the sliding rod moves obliquely downward in the fixed groove, and the lower pressing block moves obliquely downward, so that the surface material is flattened, thereby ensuring the accuracy of its cloth cutting.

[0030] Reference Figure 1 , Figure 2 as well as Figure 3 The present invention provides an injection mold for automobile interior decoration parts with an automatic cloth cutting function, comprising a working base 1, support plates 4 are arranged on both sides of the working base 1, the top ends of the two support plates 4 close to the sides of the working base 1 are fixedly connected with a leveling mechanism 5, the sides of the leveling mechanism 5 away from the working base 1 are movably connected with a connecting plate 13, the sides of the connecting plate 13 away from the leveling mechanism 5 are fixedly connected with a cloth cutting upper mold 9, the sides of the cloth cutting upper mold 9 are movably connected with a moving mechanism 7, the bottom ends of the moving mechanism 7 away from the cloth cutting upper mold 9 are movably connected with a hot pressing upper mold 10, and the cloth cutting upper mold 9 A mold control end 11 is fixedly connected to the top of the hot pressing upper mold 10, a fixed plate 6 is movably connected to the side of the moving mechanism 7, a processing lower mold 12 is fixedly connected to the middle of the top of the working base 1, a collecting roller 3 is provided on the side of the working base 1, and a collecting box 2 is fixedly connected to the side of the top of the working base 1 close to the collecting roller 3. The processing lower mold 12 can cooperate with the cloth cutting upper mold 9 and the hot pressing upper mold 10, and the top of the processing lower mold 12 is in the same plane with the top of the working base 1, the skin material is placed on the working base 1, and the collecting roller 3 can be wound around the skin material.

[0031] In the embodiment of the present application, the surface material is placed on the work base 1 and is wound by the collecting roller 3, thereby realizing the automatic loading of the surface material. In addition, it should be noted that when the present application is in use, the moving mechanism 7 can make the cloth cutting upper mold 9 and the hot pressing upper mold 10 move, and when the cloth cutting upper mold 9 and the hot pressing upper mold 10 are moving, the mold control end 11 on the cloth cutting upper mold 9 and the hot pressing upper mold 10 will move, and when the cloth cutting upper mold 9 and the hot pressing upper mold 10 are working, the mold control end 11 can control the cloth cutting upper mold 9 and the hot pressing upper mold 10 to descend, and cooperate with the processing lower mold 12. In addition, the existing technical means for the mold to perform cloth cutting and injection molding are not limited in detail in this application, and the fixed plate 6 will be fixedly connected to the external wall, so that the fixed plate 6 supports the moving mechanism 7, the blowing mechanism 8, the cloth cutting upper mold 9 and the hot pressing upper mold 10 inside it.

[0032] Reference Figure 3 The moving mechanism 7 includes a lower support plate 701 located below the fixed plate 6 and fixedly connected to the fixed plate 6, a servo motor 702 is fixedly connected to the side of the lower support plate 701, a threaded rod 703 is fixedly connected to the side of the servo motor 702 close to the lower support plate 701, a moving plate 704 is threadedly connected to the side of the threaded rod 703, a limiting rod 705 is movably connected to the side of the moving plate 704 away from the threaded rod 703, both ends of the limiting rod 705 are fixedly connected to the inside of the lower support plate 701, and the cloth cutting upper mold 9 and the hot pressing upper mold 10 can move vertically in the moving plate 704.

[0033] In the embodiment of the present application, when the servo motor 702 drives the threaded rod 703 to rotate, the movable plate 704 can move. When the movable plate 704 moves, it drives the cloth cutting upper mold 9 and the hot pressing upper mold 10 inside it to move. When the cloth cutting upper mold 9 is located above the processing lower mold 12, the mold control end 11 drives the cloth cutting upper mold 9 to move downward, and cloth can be cut at this time. When the hot pressing upper mold 10 is located above the processing lower mold 12, the mold control end 11 drives the hot pressing upper mold 10 to move downward, and injection molding and hot pressing can be performed on it. Therefore, the present application adopts a lower mold and two upper molds to cooperate to automatically realize the cloth cutting and injection molding production of automotive interior parts. The present application is more intelligent during production.

[0034] Reference Figure 3 as well as Figure 4 The movable plate 704 is provided with an avoidance groove for the operation of the blowing mechanism 8. The blowing mechanism 8 includes a rotating motor 801 fixedly connected to the movable plate 704. The bottom end of the rotating motor 801 is fixedly connected to a rotating shaft 802. The bottom end of the rotating shaft 802 is fixedly connected to an output gear 803. The side of the output gear 803 is meshed with a connecting gear 804. The top of the connecting gear 804 is fixedly connected to a synchronous gear 805. The side of the synchronous gear 805 is meshed with a speed-increasing gear 806. The inside of the speed-increasing gear 806 is fixedly connected to a blade shaft 807. The bottom end of the blade shaft 807 is fixedly connected to a rotating blade 808. The diameter of the root circle of the output gear 803 is four times the diameter of the root circle of the connecting gear 804. The diameter of the root circle of the synchronous gear 805 is four times the diameter of the root circle of the blade shaft 807.

[0035] In the embodiment of the present application, when the output gear 803 rotates, it is transmitted through the output gear 803, the synchronous gear 805 and the speed increasing gear 806. At this time, the rotating blade 808 rotates. When the rotating blade 808 rotates and passes above the processed lower mold 12, the rotating blade 808 blows air downward to blow away impurities when the surface material is cut off, and the blown surface material is leveled to make it have higher quality during subsequent injection molding. The diameter of the output gear 803 is four times the diameter of the connecting gear 804, and the diameter of the synchronous gear 805 is four times the diameter of the blade shaft 807, which increases the rotation speed of the rotating blade 808 and increases the wind force.

[0036] Reference Figure 5 , Figure 6 , Figure 7 as well as Figure 8The leveling mechanism 5 includes a fixed groove 501 fixedly connected to the support plate 4, a sliding rod 503 is movably connected inside the fixed groove 501, a sliding block 504 is fixedly connected to the side of the sliding rod 503, and a side of the sliding block 504 is movably connected to a limiting groove 505, a connecting card groove 506 is fixedly connected to the side of the limiting groove 505, and a sliding groove for the connection plate 13 to move is provided on the side of the connecting card groove 506 away from the limiting groove 505, and a connecting rod 507 is fixedly connected to the side of the sliding rod 503, and a pressing rod 507 is fixedly connected to the bottom end of the connecting rod 507. Block 508, the bottom end of the pressing block 508 and both sides of the top of the working base 1 are provided with inclined surfaces, the inclined surface of the bottom end of the pressing block 508 is adapted to the inclined surface of the top end of the working base 1, and an avoidance groove adapted to the limit component 502 is provided in the fixed groove 501, the limit component 502 includes a support shaft 5023 fixedly connected to the avoidance groove, the bottom end of the support shaft 5023 is fixedly connected to the limit plate 5022, the side of the support shaft 5023 is movably connected to a spring 5024, and the side of the support shaft 5023 is movably connected to the limit box 5021.

[0037] When the upper mold 9 for cutting cloth descends, the connecting slot 506 is driven to move downward through the connecting plate 13. When the connecting slot 506 moves downward, the limiting slot 505 drives the slider 504 and the sliding rod 503 to move downward. When the sliding rod 503 moves downward, it will synchronously drive the connecting rod 507 and the lower pressing block 508 thereunder to move downward. When the lower pressing block 508 moves downward and contacts the surface material above the working base 1, the lower pressing block 508 simultaneously pulls the surface material outward, and the slider 504 can slide in the limiting slot 505 to ensure the stability of the sliding rod 503 when it is tilted and moved. At this time, the surface material will be flattened, and before the sliding rod 503 moves to the bottom, the limiting plate 5022 will be pressed downward into the avoiding slot and the spring 5024 will be compressed. When the sliding rod 503 moves to the bottom , the sliding rod 503 moves away from the limit plate 5022, so the spring 5024 resets the limit box 5021, and when the sliding rod 503 moves upward, its side will be limited by the limit box 5021, so it will only move vertically upward for reset, so the pressing block 508 will move upward directly from above the surface material of the working base 1, and will not cause the surface material to move horizontally. Before the sliding rod 503 moves to the top, the upper limit box 5021 will enter the upper avoidance groove, and when it is completely moved to the top, it will move away from the bottom of the limit box 5021, and the limit box 5021 will limit its side to ensure that it will move vertically downward. In addition, the connecting plate 13 only cooperates with the connecting slot 506 on the side of the cloth cutting upper mold 9 when the cloth cutting upper mold 9 moves to be located above the processing lower mold 12.

[0038] The working principle of the present invention is as follows: the epidermis material is placed on the working base 1, at which time the two ends of the epidermis material are located on the inclined surfaces on both sides of the top of the working base 1, and the collecting roller 3 drives the epidermis material to move above the working base 1. When the epidermis material needs to be cut, the mold control end 11 drives the cloth-cutting upper mold 9 to move downward, and when the cloth-cutting upper mold 9 moves downward, it drives the connecting plate 13 to move downward, and when the connecting plate 13 moves downward, it drives the connecting card slot 506 to move downward, and when the connecting card slot 506 moves downward, the limiting groove 505 drives the slider 504 and the sliding rod 503 to move downward, and when the sliding rod 503 moves downward, it will synchronously drive the connecting rod 507 and the lower pressing block 508 thereunder to move downward;

[0039] When the lower pressing block 508 moves downward and contacts the surface material above the working base 1, the sliding rod 503 moves to the lowest position in the fixed groove 501 and moves vertically downward. Therefore, when the sliding rod 503 moves downward again, it moves obliquely downward. The moving angle of the sliding rod 503 is the same as the angle of the inclined surface of the bottom end of the lower pressing block 508 and the top end of the working base 1. Therefore, the lower pressing block 508 moves along the inclined surface of the top end of the working base 1. Lower pressing blocks 508 are provided on both sides of the top end of the working base 1. Therefore, the lower pressing blocks 508 on both sides simultaneously pull the surface material outward, thereby flattening the surface material, so that the cloth cutting upper mold 9 can be cut accurately enough when it moves downward. When the sliding rod 503 moves obliquely to the lowest position in the fixed groove 501, the cloth cutting upper mold 9 contacts the processing lower mold 12 to complete the cloth cutting work.

[0040] After the cloth cutting upper mold 9 cuts the cloth, the mold control end 11 controls the cloth cutting upper mold 9 to reset. When the cloth cutting upper mold 9 resets, it moves upward. At this time, the connecting slot 506 also drives the sliding rod 503 to move upward. When the sliding rod 503 moves upward, it first moves vertically toward each other and then moves upward along the inclined surface. Therefore, the lower pressing block 508 is first lifted above the working base 1 and then moves obliquely upward. The surface material on the working base 1 will not be moved, thereby ensuring the quality of the cloth after cutting.

[0041] After the cloth cutting is completed, the servo motor 702 starts and drives the threaded rod 703 to rotate. At this time, the moving plate 704 drives the cloth cutting upper mold 9 and the hot pressing upper mold 10 to move. At this time, the blowing mechanism 8 will also move as a whole. When the rotating motor 801 starts, the output gear 803 is driven to rotate through the rotating shaft 802. When the output gear 803 rotates, it is transmitted through the output gear 803, the synchronous gear 805 and the speed increasing gear 806. At this time, the rotating blade 808 rotates, and the rotating blade 808 rotates and passes through the upper part of the processing lower mold 12 When the hot pressing upper mold 10 is moved to the upper part of the processing lower mold 12, the mold control end 11 controls the hot pressing upper mold 10 to descend, and cooperates with the processing lower mold 12 to perform injection hot pressing molding to form automotive interior parts. After the hot pressing upper mold 10 is reset, the servo motor 702 drives the cloth cutting upper mold 9 and the hot pressing upper mold 10 to reset, and subsequent work can be carried out to realize automated cloth cutting and injection molding.

[0042] The formed automobile interior is located between the surface materials, which is located in the holes formed after the surface materials are cut, and the processing lower mold 12 will push out the automobile interior decoration parts. Therefore, when the collecting roller 3 drives the surface material to move, the surface material will drive the automobile interior decoration parts to move, so they will automatically fall into the collection box 2 for collection.

[0043] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
