Description

Technical Field

[0001] The utility model mainly relates to the technical field of cover plate processing, and in particular to a structure for forming two cover plates with a single mold. Background Art

[0002] With the continuous development of the automotive industry and the increasing diversification of consumer demands, automotive interior panels are gaining increasing attention. As a crucial component in modern vehicle interiors, these panels play a crucial role in the driver's user experience and driving safety. Currently, market demand for these products continues to grow, driven primarily by consumers' relentless pursuit of technological and practical features within their vehicles. Some of these products feature curved panels, whose unique design and appearance add a touch of style and technology to vehicle interiors. Curved panels are typically formed using hot-bending equipment. When processing small panels, multiple panels are placed simultaneously on a single mold to significantly improve production efficiency. However, the molding process, once the machine presses the mold, places extremely high demands on the machine's precision. Even the slightest deviation can result in the panel failing to form or failing to meet specified parameters. Utility Model Content

[0003] 1. Technical problems to be solved by the utility model:

[0004] The utility model provides a single-mold two-piece cover plate molding structure, which is used to solve the technical problems existing in the above-mentioned background technology.

[0005] 2. Technical solution:

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a single-mold two-piece cover plate molding structure, including a mounting plate, a heating mechanism is provided on the mounting plate, the heating mechanism includes a first lifting mechanism fixed to the upper end of the mounting plate, a heating fixing plate is provided on the output end of the first lifting mechanism, a plurality of heating wires are provided in the heating fixing plate, two pressing mechanisms are symmetrically provided on both sides of the first lifting mechanism, the pressing mechanism includes a second lifting mechanism, and a pressing plate is provided on the output end of the second lifting mechanism.

[0007] Preferably, an active plate is fixedly installed on the output end of the first lifting mechanism, and a plurality of first guide shafts are fixedly installed on the lower end of the active plate. The first guide shafts are slidably installed on the mounting plate, and a connecting plate is fixedly installed on the lower end of the first guide shaft. The connecting plate is arranged below the mounting plate, and the connecting plate is used to install the heating fixing plate.

[0008] Preferably, the first lifting mechanism includes a first mounting bracket fixed on the mounting plate, a first screw rod is rotatably mounted on the first mounting bracket, the upper end of the first screw rod is fixedly connected to the first servo motor, a first screw rod nut is mounted on the first screw rod, and the first screw rod nut is connected to the active plate.

[0009] Preferably, an active frame is fixedly installed on the output end of the second lifting mechanism, and a plurality of second guide shafts are fixedly installed on the lower end of the active frame. The lower ends of the second guide shafts pass through the active plate, the mounting plate, the connecting plate and the heating and fixing plate in sequence and are connected to the lower pressure plate.

[0010] Preferably, the second lifting mechanism includes a second mounting frame fixed on the active plate, a second screw rod is rotatably mounted on the second mounting frame, the upper end of the second screw rod is fixedly connected to the second servo motor, a second screw rod nut is mounted on the second screw rod, and the second screw rod nut is connected to the active frame.

[0011] 3.Beneficial effects:

[0012] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0013] The heating wire in the heating mechanism of the present invention continuously heats the lower pressing plate in the pressing mechanism. When the mold reaches the station, the heating mechanism descends to the specified position. Then, the two lower pressing plates in the pressing mechanism respectively apply pressure to the corresponding upper mold until the cover plate is formed. Finally, the lower pressing plate returns to the initial position, and the heating mechanism also returns to the initial position. At this point, the two cover plates achieve curved surface forming. Traditional structures usually find it difficult to efficiently form two cover plates at the same time in a single-mold situation. However, this structure, through clever design, can achieve simultaneous forming of two cover plates in the mold in a single-mold state. The heating wire in the heating mechanism can quickly and continuously heat the lower pressing plate in the pressing mechanism. When the mold reaches the station, it can quickly enter the forming stage, reducing waiting time and pauses between processes, and greatly improving production efficiency.

[0014] While sharing a common lower die, this new design utilizes a separate upper die for each cover panel, each with its own lower pressing plate. This allows each cover panel to be formed independently, ensuring that the two panels do not interfere with each other during the forming process. Conventional structures can experience uneven force distribution due to simultaneous pressure on both panels, leading to poor forming results. This design, in which the two cover panels are formed independently, better ensures that the molding parameters for each cover panel meet requirements, improving yield rates.

[0015] The present invention adopts a first lifting mechanism and a second lifting mechanism to accurately control the positions of the heating fixing plate and the lower pressure plate, respectively. For example, the first lifting mechanism drives the first screw to rotate through the first servo motor, so that the first screw nut drives the active plate to move, and then ensures that the heating fixing plate moves up and down smoothly to the specified position through the first guide shaft. The second lifting mechanism is similar. Through the cooperation of the second servo motor, the second screw and the second screw nut, and the guiding effect of the second guide shaft, the lower pressure plate is accurately controlled to apply pressure to the corresponding upper mold. Compared with the traditional structure, this precise control method can better ensure uniform pressure and accurate position during the molding process, thereby improving the molding quality of the cover plate.

[0028] An active plate 3 is fixedly installed on the output end of the first lifting mechanism 2, and a plurality of first guide shafts 4 are fixedly installed on the lower end of the active plate 3. The first guide shafts 4 are slidably installed on the mounting plate 1 up and down, and a connecting plate 5 is fixedly installed on the lower end of the first guide shaft 4. The connecting plate 5 is arranged below the mounting plate 1, and the connecting plate 5 is used to install the heating fixing plate 6.

[0029] The first lifting mechanism 2 includes a first mounting frame 21 fixed on the mounting plate 1, and a first screw rod 23 is rotatably mounted on the first mounting frame 21. The upper end of the first screw rod 23 is fixedly connected to the first servo motor 22, and a first screw rod nut 24 is installed on the first screw rod 23, and the first screw rod nut 24 is connected to the active plate 3.

[0030] An active frame 9 is fixedly installed on the output end of the second lifting mechanism 8, and a plurality of second guide shafts 10 are fixedly installed on the lower end of the active frame 9. The lower ends of the second guide shafts 10 pass through the active plate 3, the mounting plate 1, the connecting plate 5 and the heating and fixing plate 6 in sequence and are connected to the lower pressure plate 11.

[0031] The second lifting mechanism 8 includes a second mounting frame 81 fixed on the active plate 3, and a second screw rod 83 is rotatably mounted on the second mounting frame 81. The upper end of the second screw rod 83 is fixedly connected to the second servo motor 82, and a second screw rod nut 84 is mounted on the second screw rod 83. The second screw rod nut 84 is connected to the active frame 9.

[0032] Working principle:

[0033] First, the heating wires 7 within the heating fixture plate 6 begin to operate, continuously heating the lower platen 11 in the pressing mechanism to the required temperature for thermoforming the cover sheet. When the mold reaches this position, the first lifting mechanism 2 lowers the heating fixture plate 6 to a designated position, allowing the heated lower platen 11 to approach the mold for the forming operation.

[0034] Start the first lifting mechanism 2. The first servo motor 22 drives the first screw 23 to rotate, causing the first screw nut 24 to move up and down, thereby driving the active plate 3 to move. Several first guide shafts 4 fixed at the lower end of the active plate 3 slide up and down on the mounting plate 1 to ensure the stability of the movement. The active plate 3 drives the connecting plate 5 to move through the first guide shaft 4, and the connecting plate 5 moves with the heating and fixing plate 6. The precise control of the first servo motor 22 and the first screw 23 is used to achieve high-precision position adjustment of the heating and fixing plate 6. The first guide shaft 4 ensures the stability and linearity of the movement process, prevents shaking or offset, and improves the reliability and molding accuracy of the equipment.

[0035] Start the second lifting mechanism 8. The second servo motor 82 drives the second screw 83 to rotate, causing the second screw nut 84 to move up and down, thereby driving the active frame 9 to move. Several second guide shafts 10 fixed to the lower end of the active frame 9 pass through the active plate 3, the mounting plate 1, the connecting plate 5 and the heating and fixing plate 6 in sequence, and then drive the lower pressure plate 11 to move. The second servo motor 82 and the second screw 83 are used to achieve precise position control of the lower pressure plate 11. The second guide shaft 10 ensures the straightness and stability of the movement of the lower pressure plate 11, ensuring that the lower pressure plate 11 can accurately apply pressure to the corresponding upper mold.

[0036] The lower pressing plates 11 of the two pressing mechanisms each apply pressure to the corresponding upper mold. The combined effects of pressure and heat gradually shape the cover into a curved surface. Independent pressing mechanisms apply pressure to each cover individually, ensuring that the two cover sheets do not interfere with each other during the forming process, improving yield. Precisely controlled pressure ensures more uniform cover sheet formation, enhancing product quality and consistency.

[0037] Finally, the second lifting mechanism 8 returns the lower platen 11 to its initial position, and the first lifting mechanism 2 returns the heated and fixed plate 6 to its initial position, preparing for the next molding operation. This rapid reset allows the equipment to efficiently proceed with the next production cycle, improving production efficiency. Accurate reset ensures a consistent starting position for each operation, further improving the stability and precision of the molding process.
