[0025] Example 1

[0026] like Figure 1-2As shown, an apparatus for lightweight molding of seat back panels mainly consists of a base 1 and a flipping assembly, a locking assembly, and a foaming mold disposed on the base 1. The foaming mold includes an upper mold 7 and a lower mold 8. The interior of the upper mold 7 and the interior of the lower mold 8 form a foaming cavity. The upper surface of the lower mold 8 is provided with a plurality of hanging nails 9 around the foaming cavity. The hanging nails 9 are used to fix the back panel skin 11 to the upper surface of the lower mold 8. The lower surface of the upper mold 7 is provided with a docking hole 10 corresponding to the position of each hanging nail 9. When the upper mold 7 and the lower mold 8 are closed, the hanging nails 9 are completely embedded in the docking holes 10, and the back panel skin 11 is fixed between the upper mold 7 and the lower mold 8. The flipping assembly and the locking assembly are used to fix or loosen the foaming mold.

[0027] In this embodiment, the top of the upper mold 7 is also provided with a bubble injection port 12, which is connected to the foaming cavity.

[0028] In this embodiment, the surface of the foaming cavity of the lower mold 8 is uniformly distributed with vacuum adsorption holes, the diameter of the vacuum adsorption holes is 0.8 mm, and the spacing between the vacuum adsorption holes is 1.5 mm.

[0029] In this embodiment, both the upper mold 7 and the lower mold 8 are square.

[0030] In this embodiment, there are four hanging nails 9, which are respectively located at the four corners of the upper surface of the lower mold 8.

[0031] like Figure 1 As shown, the flipping assembly includes an upper mold frame 3, a lower mold frame 2, and a flipping cylinder 4. The inner wall of the upper mold frame 3 can fit tightly against the upper surface of the upper mold 7, and the inner wall of the lower mold frame 2 can fit tightly against the lower surface of the lower mold 8. The upper mold frame 3 and the lower mold frame 2 are connected by a hinge. The flipping cylinder 4 is connected to one side of the upper mold frame 3, and the piston rod of the flipping cylinder 4 is connected to one side of the base 1. The flipping cylinder 4 drives the upper mold frame 3 to rotate around the hinge, realizing the opening and closing of the upper mold frame 3 relative to the lower mold frame 2. When compressed air enters the flipping cylinder 4, it pushes out the piston rod, causing the upper mold frame 3 to close. When the compressed air is discharged, the piston rod retracts, causing the upper mold frame 3 to flip upward and open.

[0032] The top of the upper mold frame 3 has a round hole that matches the foam injection port 12, which facilitates the injection of foaming agent.

[0033] like Figure 1As shown, the locking assembly includes a locking cylinder 5 and a locking element 6. The locking cylinder 5 is located at the bottom of the base 1. The piston rod of the locking cylinder 5 is connected to the locking element 6 via a hinge. The locking cylinder 5 drives the locking element 6 to rotate around the hinge, thereby locking or releasing the upper and lower mold frames. When compressed air enters the locking cylinder 5, it pushes out the piston rod, causing the locking element 6 to lock the upper and lower mold frames. When the compressed air is discharged, the piston rod retracts, causing the locking element 6 to be in a released state.

[0034] Working principle: When using this utility model, the upper mold frame 3 is first flipped upward to open, and the lower mold 8 is placed in. The back plate skin 11 is hung on the hanging nail 9 on the upper surface of the lower mold 8. The lower mold 8 is vacuumed, and then the upper and lower molds are closed. The flipping cylinder 4 drives the upper mold frame 3 to flip downward around the hinge, and the locking cylinder 5 drives the locking part 6 to rotate around the hinge, so that the locking part 6 locks the upper and lower mold frames. Then, the foaming agent is injected into the foaming cavity through the foaming hole 12. After natural curing, the product is taken out.

[0035] The device provided by this utility model has a simple structure and is easy to operate, and can be applied to the rapid prototyping of lightweight automotive back panels.

[0036] The above description of the embodiments is provided to enable those skilled in the art to understand and use the present invention. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
