[0002] Car interiors are not just decorations; they are an important part of what drivers and passengers directly touch, feel, and interact with. They directly affect the comfort, convenience, safety, and overall experience of driving and riding in a vehicle. As people pay more and more attention to the overall quality of cars, the design of modern car interiors is receiving more and more attention, and has even become an important aspect for many brands to showcase their core competitiveness.

[0003] Vacuum forming of automotive interior parts is a specialized process optimized for specific needs of vehicle components. Its core is to use vacuum adsorption to heat and soften plastic sheets to create thin-walled parts that conform to the interior design, such as dashboard lower guards, door panel trims, glove box trims, seat guards, and trunk side trims, balancing cost and design flexibility. In the vacuum forming process of automotive interior parts, lifting the lower mold for mold closing is a crucial step. Currently, there is a lack of a highly automated and efficient lifting mechanism in existing production equipment. Summary of the Invention

Figure 1 , Figure 5 As shown, the system includes a lifting bracket 1, two lifting carriages 2, a lifting motor 3, and a lower mold lifting platform 5. The lower mold lifting platform 5 and the lifting bracket 1 are arranged sequentially. The two lifting carriages 2 are slidably arranged on both sides inside the lifting bracket 1, and the two lifting carriages 2 are connected by a crossbar. The two lifting carriages 2 extend to one side of the lower mold lifting platform 5 and are connected to a carriage extension arm 4. The carriage extension arm 4 is connected to the lower mold lifting platform 5. Support frames 21 are provided on both sides of the carriage extension arm 4, and the support frames 21 are fixedly connected to the lifting bracket 1. Several universal balls 22 are provided on the top of the lifting carriages 2 and the support frames 21. The lifting motor 3 is located on one side of the lower mold lifting platform 5. The output end of the lifting motor 3 is connected to a rotating shaft 6. Two drive sprockets 7 that cooperate with the lifting carriage 2 are installed on the rotating shaft 6. Figure 7 As shown, a rigid chain actuator 8 is provided below each of the two lifting carriages 2. A driven sprocket 9 is provided at the input end of the rigid chain actuator 8. A transmission chain 10 is connected between the two driving sprockets 7 and the driven sprockets 9 on the same side. The output end of the rigid chain actuator 8 is connected to the bottom of the lifting carriage 2 on the same side. Several guide sprockets 28 are provided on the inner side of the two support frames 21, and the transmission chain 10 rotates along the guide sprockets 28. The inner side of the lifting bracket 1 is provided with several guide rails 19, and the outer sides of the two lifting brackets 2 are each provided with several sliders 20 that cooperate with the guide rails 19, and the sliders 20 that cooperate with the guide rails 19 are slidably connected.

[0019] like Figure 4 As shown, the outer sides of the two lifting carriages 2 are each rotatably mounted with a synchronous shaft 12 via a bearing seat 11. The synchronous shaft 12 is provided with several synchronous gears 13. Several racks 14 that mesh with the synchronous gears 13 are vertically arranged on both sides of the lifting bracket 1. Each rack 14 is provided with a rack 15, and the synchronous gears 13 mesh with the racks 15.

[0020] Guide rods 16 are provided on both sides of the lifting bracket 1. A brake 17 is slidably mounted on each guide rod 16. A fixed seat 18 is installed on the brake 17 and the fixed seat 18 is connected to the lifting slide 2.

[0021] like Figure 2 , Figure 3 As shown, the output end of the lifting motor 3 is connected to the output shaft 23 via a coupling. The output shaft 23 is connected to the rotating shaft 6 via a coupling. One end of each of the two support frames 21 is provided with a bearing seat 24. The rotating shaft 6 is rotatably mounted on the two bearing seats 24.

[0022] like Figure 8 As shown, the lower mold lifting platform 5 is provided with several mold positioning columns 25, which are used for positioning and fixing the lower mold.

[0023] like Figure 6 As shown, a distance sensor 26 and a limit switch 27 are provided on the inner side of the lifting bracket 1.

[0024] The process of using this invention: Two lifting slides 2 are installed on the inner side of the lifting bracket 1. The inner side of the lifting bracket 1 is provided with a guide rail 19, and the outer side of the lifting slide 2 is provided with a slider 20. The lifting slide 2 slides up and down along the guide rail 19 on the lifting bracket 1 via the slider 20. The lifting slide 2 is connected to the lower mold lifting platform 5 via the slide extension arm 4. The lower mold lifting platform 5 supports the lower mold and moves up and down with the lifting slide 2, thereby realizing the lifting and lowering motion of the lower mold. The lifting motor 3 is connected to the rotating shaft 6 via the output shaft 23 and the coupling. Two drive sprockets 7 are installed on the rotating shaft 6. Rigid chain actuators 8 are installed below the two lifting carriages 2 respectively. A driven sprocket 9 is installed at the input end of the rigid chain actuator 8. The drive sprocket 7 drives the driven sprocket 9 through the transmission chain 10. The driven sprocket 9 drives the operation of the rigid chain actuator 8. The output end of the rigid chain actuator 8 is connected to the bottom of the lifting carriage 2. The lifting carriage 2 is driven to move up and down through the rigid chain actuator 8. Both lifting slides 2 have a synchronous shaft 12 mounted on their outer sides via a bearing seat 11. Two synchronous gears 13 are mounted on the synchronous shaft 12. Two rack frames 14 are mounted on each side of the lifting bracket 1. Rack frames 14 are equipped with racks 15. The synchronous gears 13 mesh with the racks 15 respectively. When the rigid chain actuator 8 drives the lifting slides 2 to move up and down, the synchronous gears 13 move up and down along the racks 15, so that the front and rear ends of the lifting slides 2 can rise or fall synchronously, thus avoiding the lifting slides 2 from tilting and becoming unbalanced. Guide rods 16 are provided on both sides of the lifting bracket 1. A brake 17 is slidably installed on the guide rods 16. The brake 17 is connected to the lifting slide 2 through the fixed seat 18. When the lifting slide 2 is running normally, the brake 17 slides up and down along the guide rods 16 with the lifting slide 2. In case of an accident, the brake 17 will hold the guide rods 16 to brake, so as to prevent the lifting slide 2 from falling accidentally and ensure safety.

[0025] A distance sensor 26 and a limit switch 27 are provided on the inner side of the lifting bracket 1. The position of the lifting slide 2 is determined by the distance sensor 26. When the lifting slide 2 moves to the appropriate position, the limit switch 27 controls the opening and closing of the movement of the lifting slide 2. When the lifting slide 2 is moved to the bottom of the lifting bracket 1, the top of the lifting slide 2 is flush with the top of the support frame 21. Both the top of the lifting slide 2 and the support frame 21 are equipped with universal balls 22, which can be used to replace the lower mold. The lower mold is placed on the lifting slide 2 from the rear side of the lifting bracket 1 and pushed to slide along the top of the lifting slide 2 and the support frame 21.

Therefore, equivalent variations made according to the claims are still within the scope of this invention.
