Technical Field

[0001] The utility model belongs to the technical field of automobile interior trim panel shaping devices, in particular to an automobile interior trim panel shaping device. Background Art

[0002] With the rapid development of automobile technology, cars are becoming more and more popular in ordinary families. Users have higher and higher requirements for the overall quality of cars, especially the refinement, comfort and luxury of car interiors. To meet users' requirements for car interiors, various manufacturing processes of car interiors are indispensable. In the production process, most car interior panels are formed by injection, injection molding or blister molding. The main principle of the blister molding process is: after the flat plastic sheet is heated and softened, it is vacuum adsorbed on the mold surface and formed after cooling, so as to realize the processing and molding of the car interior panel. However, when processing the car interior panel by this blister molding process, it is first necessary to place the car interior panel on the tooling to be processed, and then move the heating device to heat and soften the sheet placed on the tooling, and then remove the heating device, and move the mold to the bottom of the sheet through the lifting device to promote blister molding. In the prior art, the heating efficiency of the heating mechanism for the sheet is low, and it is easy to have uneven heating and softening effects in various places due to factors such as airflow in the working environment. After the blister molding is completed, it is necessary to wait for it to cool and shape naturally before it can be removed, which wastes too much time and affects the processing and production efficiency.

[0023] refer to Figure 1-5 A device for shaping an automobile interior panel comprises a panel 24, the panel 24 has an opening, a pressing frame 44 is arranged on the panel 24, the pressing frame 44 is fixedly connected to the panel 24 by bolts, a box body 34 covering the pressing frame 44 is fixedly connected to the panel 24, two slide grooves 35 are symmetrically arranged on both sides of the box body 34, a plurality of slide rods 43 are slidably connected between the two slide grooves 35, a flexible covering cloth 36 is connected between the plurality of slide rods 43, four support rods 32 are symmetrically distributed and fixedly connected on the bottom side plane of the box body 34, and heaters 33 for heating and softening the material plate are fixedly connected to the upper ends of the four support rods 32.

[0024] The covering cloth 36 is pulled to cover the interior trim panel, so as to prevent dust from falling on the interior trim panel which has not been completely cooled and shaped and affecting the quality of the finished product.

[0025] refer to Figure 5 A filter box 39 is fixedly connected to one side of the box body 34, and a through hole 42 is opened on the filter box 39 and is connected to the inside of the box body 34. An axial flow fan 37 connected to the through hole 42 is fixedly connected to the side of the filter box 39 away from the box body 34. A filter element 41 is arranged in the filter box 39, and a box cover 38 is fixedly connected to the upper end of the filter box 39.

[0026] The airflow generated by the axial flow fan 37 is used to cool the interior trim panel, thereby accelerating its cooling and shaping process and improving processing efficiency. The airflow generated by the axial flow fan 37 is filtered by the filter element 41 to prevent impurities mixed in the airflow from affecting the appearance and surface quality of the interior trim panel.

[0027] refer to Figure 1-2 The panel 24 is rotatably connected to a movable plate 29 at an unclosed side of the box body 34 , and connecting pieces 31 are symmetrically distributed and fixedly connected at both ends of the movable plate 29 . Each connecting piece 31 is fixed to the box body 34 by a latch 40 , and a handle 30 is fixedly connected to the outer side of the movable plate 29 .

[0028] The movable plate 29 is provided to facilitate workers to carry out loading and unloading operations.

[0029] refer to Figure 3 Four legs 25 are fixedly connected at the four corners of the bottom of the panel 24, a bottom plate 26 is fixedly connected between the bottoms of the four legs 25, four cylinders 27 are fixedly connected to the bottom plate 26, and the extended ends of the four cylinders 27 are fixedly connected to the blister molds 28 corresponding to the opening positions of the panel 24.

[0030] In this embodiment, initially, the operator connects the power supply and the control system of the present invention, at which time the movable plate 29 is in an open state and the covering cloth 36 is in a retracted state. The operator then stands on the movable plate 29, screws the bolts to remove the pressing frame 44, and then places the material sheet to be processed by blister forming, and installs and fixes the pressing frame 44 again, so that the pressing frame 44 can stably and fixedly clamp the material sheet.

[0031] Subsequently, the operator flips up the movable plate 29 to align the holes between the connecting piece 31 and the box body 34, and then inserts two pins 40 in sequence to fix the movable plate 29 to the box body 34, and starts the heater 33 to heat and soften the material plate. When the material plate reaches a suitable softening effect, the heater 33 is turned off, and then the cylinder 27 is controlled to push the blister mold 28 to rise and contact the material plate. A vacuum pump separately arranged outside the device is used to suck out the air in the gap between the blister mold 28 and the material plate for blister processing to form an interior panel.

[0032] At this time, the operator pulls the covering cloth 36 to make the slide bar 43 slide in the slide groove 35, so that the covering cloth 36 is evenly unfolded and covers the upper end of the box body 34, thereby preventing dust and impurities from falling on the surface of the interior panel from above. At the same time, the axial flow fan 37 is started to blow air into the box body 34, thereby accelerating the cooling and shaping of the interior panel, and the airflow generated by the axial flow fan 37 will be blown out from the gap between the covering cloth 36 and the box body 34, further preventing dust and impurities from entering through the gap between the covering cloth 36 and the box body 34.

[0033] The airflow generated by the axial flow fan 37 will first pass through the filter element 41, and the filter element 41 will be used to filter the impurities in the airflow to ensure that the airflow blown into the box 34 acting on the interior panel is clean and free of impurities, thereby further preventing impurities from adhering to the interior panel and affecting the appearance and surface quality of the interior panel.

[0034] After the interior panel is cooled and formed, the axial flow fan 37 is turned off and the cover cloth 36 is reset, and the cylinder 27 is controlled to retract to reset the blister mold 28, the two latches 40 are pulled out and the movable plate 29 is flipped downward, and then the bolts can be screwed to remove the pressure frame 44, and the formed interior panel can be removed.

[0035] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
