Description

Technical Field

[0001] This utility model relates to the field of automotive solid wood interior technology, specifically an intelligent automotive solid wood interior molding device. Background Technology

[0002] Automotive wood interior trim refers to the use of natural or engineered wood to decorate interior components such as dashboards, door panels, center consoles, steering wheels, and trim strips. This interior design typically uses high-grade woods such as beech and mahogany to highlight the car's luxurious feel.

[0003] In existing technologies, printing is often used to process solid wood interior trim in automobiles. However, printing results in finished products that lack texture and feel, have insufficient pattern realism, and have a strong plastic feel. In addition, printing emits VOCs, the wood grain patterns are not realistic enough, and the printing inks are not environmentally friendly, have an odor at high temperatures, and the adhesion between the color printing ink and the cover ink, as well as between the ink and the plastic parts, is not strong enough, making them prone to delamination. Moreover, they are even more prone to delamination after weathering and aging tests. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A smart automotive solid wood interior molding device, such as Figures 1-4 As shown, the system includes a base plate 1, a support plate 2 and a lower mold 7 fixedly mounted on the upper surface of the base plate 1, an upper mold 5 movably mounted above the lower mold 7, a bearing plate 4 fixedly mounted on the upper surface of the upper mold 5, a spiral blade 10 fixedly mounted on the upper surface of the bearing plate 4, a cylinder 3 mounted on the upper surface of the support plate 2, connecting plates 6 on both sides of the bearing plate 4, and the connecting plates 6 are fixedly connected to the output end of the cylinder 3. A fixing mechanism is provided on the upper surface of both connecting plates 6. Several heating rods 22 are installed inside the upper mold 5. A wave-shaped groove 2 9 is opened on the bottom surface of the upper mold 5. A wave-shaped groove 1 8 is opened at the bottom of the lower mold 7. The wave-shaped groove 1 8 and the wave-shaped groove 2 9 cooperate with each other. The wave-shaped groove 1 8 and the wave-shaped groove 2 9 can match the curved surface shape of the automotive interior, achieving 3D shallow stretching of the wood chips and avoiding fiber breakage.

[0026] Both connecting plates 6 have connecting blocks 11 fixedly connected to their bottom surfaces. Both connecting blocks 11 have connecting shafts 12 rotatably connected to their outer walls. One end of each connecting shaft 12 is fixedly connected to the upper mold 5. A motor is installed on the outer wall of one of the connecting blocks 11, and the motor output end is connected to the connecting shaft 12. The motor model is 28BYJ-48.

[0027] In use, solid wood is mechanically processed and cut into thin slices. Solid wood fiber is glued to the back of the veneer to prevent it from becoming brittle and easily broken. The processed veneer is then placed inside the lower mold 7, and the connecting plate 6 is moved down by the cylinder 3, which in turn moves the bearing plate 4 and the upper mold 5 down to close the mold. At the same time, the heating rod 22 is activated to heat the upper mold 5, so that the upper mold 5 heats and presses the veneer to soften it. The upper mold 5, in conjunction with the lower mold 7, performs shallow stretching and 3D forming of the veneer using a cylinder.

[0028] After molding, the upper mold 5 is moved upward by the cylinder 3 to release the pressure on the wood veneer. Then, the connecting shaft 12 is rotated by the motor, which rotates the upper mold 5 by 180°, causing the paper blade 10 to flip and face the wood veneer. At this time, the paper blade 10 can be moved downward by the cylinder 3 to trim the wood veneer formed in the lower mold 7, removing the excess edges. This achieves precise trimming within the mold, avoids damage to the wood grain during secondary processing, and improves efficiency.

[0029] Finally, the processed wood veneer is placed in an injection mold and injection molded to produce wood veneer textured plastic parts, forming a composite automotive interior part of real wood and plastic. The use of the injection mold is existing technology and will not be elaborated here.

[0030] The fixing mechanism includes a fixing block 13, which is fixedly connected to the outer wall of the bearing plate 4. One end of the fixing block 13 is rotatably connected to a rotating block 14 via a shaft. A limiting plate 15 is movably installed at the end of the rotating block 14 away from the fixing block 13. A slot 20 is provided through the outer wall of the limiting plate 15. A telescopic connecting rod 18 is fixedly connected to the inner wall of the limiting plate 15, and one end of the telescopic connecting rod 18 is fixedly connected to the rotating block 14. A return spring is sleeved on the outside of the telescopic connecting rod 18.

[0031] The fixing mechanism also includes an L-shaped block 16, which is fixedly installed on the upper surface of the connecting plate 6. One end of the L-shaped block 16 fits into the slot 20. A movable groove is provided on the upper surface of the L-shaped block 16, and a locking block 17 is inserted into the movable groove. A slot 19 is provided through the upper surface of the limiting plate 15, and the slot 19 fits into the locking block 17. A return spring is installed between the bottom end of the locking block 17 and the bottom end of the movable groove. The locking block 17 is inserted into the slot 19, fixing the position between the limiting plate 15 and the L-shaped block 16. This fixes the position between the bearing plate 4 and the connecting plate 6. Under the action of the return spring, the limiting plate 15 can be driven to be sleeved on the outside of the L-shaped block 16 through the slot 20.

[0032] Several guide posts 21 are installed between the upper end of the base plate 1 and the inner top of the support plate 2, and the connecting plate 6 is sleeved on the outside of the guide posts 21. The cylinder 3 pushes the connecting plate 6 down, and the guide posts 21 play a guiding role when the mold is closed, so that the upper mold 5 covers the lower mold 7 more accurately.

[0033] Specifically, by rotating the rotating block 14 and moving the limiting plate 15 away from the rotating block 14, the telescopic connecting rod 18 is stretched, and the first return spring is stretched, causing the limiting plate 15 to move away from the end of the L-shaped block 16. At this time, the limiting plate 15 is released, and under the action of the return spring 1, the limiting plate 15 can be driven to be sleeved on the outside of the L-shaped block 16 through the slot 20. During the sleeved process, the inner wall of the slot 20 presses the locking block 17, causing the locking block 17 to move down into the movable groove and press the second return spring until it is completely sleeved on the outside of the L-shaped block 16. Under the action of the return spring 2, the locking block 17 can be driven to be locked into the slot 19, fixing the position between the limiting plate 15 and the L-shaped block 16. This fixes the position between the bearing plate 4 and the connecting plate 6, making the upper mold 5 more stable and preventing shaking when pressing down the veneer. Similarly, when rotating the upper mold 5, the connection between the limiting plate 15 and the L-shaped block 16 can be released to avoid interfering with the rotation of the upper mold 5.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
