Description

Technical Field

[0001] This utility model relates to the technical field of vacuum forming of automotive interiors, and in particular to a curing device for vacuum forming of automotive interiors. Background Technology

[0002] With the increasing popularity of automobiles, people's demands for cars are also rising. The car interior is a crucial component, and its quality directly impacts the overall class of the vehicle. Therefore, to meet these demands, it is essential to improve the quality of car interiors. Nowadays, car interiors are often designed with leather upholstery, which requires a curing process to solidify the leather covering the frame during manufacturing.

[0003] A search revealed Chinese Patent Publication No. CN215974951U, which discloses a curing device for automotive interior trim panels. The device includes a curing body comprising a box-type support assembly, a substrate, a vacuum assembly, and a needle roller assembly. The substrate is fixedly mounted on the box-type support assembly, and the trim panel is placed on the substrate. The substrate has a first through hole. The vacuum assembly is mounted on the box-type support assembly, with one end connected to the first through hole. The vacuum assembly is used to create a vacuum environment for the trim panel on the substrate. The needle roller assembly includes several needles embedded in the substrate, allowing the trim panel to move on the substrate under the action of the needles. This curing device embeds the needle roller assembly into the substrate surface, enabling workers to easily and conveniently perform loading operations and preventing the trim panel's mold from scratching or damaging the substrate surface.

[0004] In summary, existing curing devices typically use only cold air and UV lamps to cure products. However, this method is slow and has a narrow temperature control range, which may cause localized overheating or overcooling.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a curing device for vacuum forming of automotive interiors, making it more valuable for industrial applications. Utility Model Content

[0032] Example

[0033] like Figures 1-4 As shown,

[0034] A curing device for vacuum forming of automotive interior trim includes a frame 1 and a conveyor belt 2. The conveyor belt 2, which runs in a left-right direction, is mounted on the frame 1. A frame cover 3 is mounted in the middle of the frame 1, and a top cover 6 is mounted on the top of the frame cover 3. Doors 4 are installed on both the left and right sides of the frame cover 3, and windows 5 are installed on both the front and rear sides of the frame cover 3.

[0035] 1. A curing lifting module 13 is installed inside the outer casing 3 of the frame:

[0036] The curing lifting module 13, from bottom to top, includes a lower support 16, a lifting movable support 17, and an upper support 18. The lower support 16 is mounted on the frame 1, and the upper support 18 is mounted on the bottom of the top cover 6. The lifting motor module 19, mounted on the frame 1 on one side of the lower support 16, drives the lifting movable support 17 to move vertically via a lifting screw 20. A UV lamp mounting cover 23 is mounted on the lifting movable support 17, and a UV lamp is installed inside the UV lamp mounting cover 23. A follower cover 22 is mounted on the top of the UV lamp mounting cover 23, located inside the bottom of the top cover 6. Cold air guide components 24 are mounted on the lifting movable supports 17 on both the left and right sides of the UV lamp mounting cover 23.

[0037] Several guide columns 21 are installed between the lower support 16 and the upper support 18, and the lifting movable support 17 moves vertically along the guide columns 21.

[0038] 2. Structural distribution of hot air ducts:

[0039] Hot air branch ducts 11 are installed on both the left and right sides of the top of the frame cover 3. The hot air main duct 7 installed on one side of the frame 1 is connected to the hot air branch duct 11 through the hot air fan 10. The hot air branch duct 11 is connected to the UV lamp mounting cover 23.

[0040] Hot air provides the necessary heat to promote the curing reaction, thereby accelerating the UV curing process.

[0041] 3. Structural distribution of cold air ducts:

[0042] A cold air branch duct 12 is installed on the frame cover 3 inside the hot air branch duct 11. The cold air main duct 8 installed on one side of the frame 1 is connected to the cold air branch duct 12 through a cold air fan. The cold air branch duct 12 is connected to the cold air guide assembly 24.

[0043] The cold air guiding assembly 24 includes a cold air guiding box 25, and several air diverting plates 26 are installed at the air outlet of the cold air guiding box 25. The air diverting plates 26 are rotatably installed at the air outlet of the cold air guiding box 25, so that the air direction can be manually adjusted.

[0044] Cooling air helps dissipate heat quickly, preventing the equipment from overheating and thus shortening the entire curing cycle. Furthermore, the cooling system can automatically activate when the equipment is not in use during UV curing, effectively reducing standby power consumption.

[0045] 4. Structural distribution of the recovery air duct:

[0046] A recovery branch air duct 14 is installed on the frame 1 directly below the curing lifting module 13. The recovery branch air duct 14 is connected to the recovery main air duct 9 installed on one side of the frame 1 via a recovery fan 15. The waste gas and dust generated during the curing process are uniformly recovered and treated through the recovery air duct.

[0047] By using hot and cold air in combination, temperature changes during the curing process can be better controlled, avoiding localized overheating or undercooling, thus ensuring curing quality. Hot air provides the necessary heat to promote the curing reaction, while cold air helps to dissipate heat evenly, reducing curing quality problems caused by uneven temperature.

[0048] Proper temperature control can reduce the risk of equipment damage due to overheating and extend the equipment's lifespan. Cooling systems effectively dissipate heat, preventing overheating and thus reducing equipment failures and maintenance needs caused by high temperatures.

[0049] In addition, the connection structure between the aforementioned multiple air ducts and their air inlets and outlets can be a structure for connecting flexible hoses.
