Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a thermoforming mold for automotive parts that can utilize waste heat. Background Technology

[0002] Automotive parts refer to the independent components and assemblies that make up various systems of a car (such as engine, transmission, chassis, body, electrical, etc.) and work together to achieve functions such as driving, steering, braking, power output, and information interaction. They cover thousands of specialized products, from core engine components (such as cylinders and crankshafts) to exterior body parts (such as bumpers and headlights) and electrical systems (such as sensors and ECUs). Thermoforming molds are key tooling in the thermoforming process, used to process thermoplastic sheets or metal materials into products of specific shapes at high temperatures.

[0003] According to a patent published on the China Patent Network, the patent title is "A Thermoforming Mold for an Automotive Sunroof Panel," patent application number 202420242145.1. It includes a lower mold and an upper mold. Multiple hydraulic rods are fixedly connected to the bottom of the upper mold, and the output ends of these hydraulic rods are fixedly connected to the top of the lower mold. Multiple supports are evenly fixedly connected to both sides of the lower mold, and cooling components are respectively installed inside the supports. A transmission component for driving the cooling components is installed at the bottom of the upper mold. The cooling components effectively maintain the surface temperature of the lower and upper molds within a suitable range, ensuring their stability and service life. The transmission component effectively drives the cooling components, improving energy utilization. A speed-increasing mechanism increases the speed of the fan blades, allowing for faster rotation and improved cooling efficiency. However, the thermoforming mold generates high temperatures during part processing. This heat is generally directly dissipated and cannot be recycled, leading to energy loss and impacting environmental friendliness.

[0004] Therefore, it is necessary to design and modify the thermoforming mold to effectively prevent the direct loss of heat that cannot be recycled and reused. Utility Model Content

A valve 11 is installed at the top of the drain pipe 10.

[0032] refer to Figure 1 , Figure 2 and Figure 3 A pipe adjustment mechanism 12 is movably connected to the top right side of the water tank 9 via a bearing. The pipe adjustment mechanism 12 includes a positive and negative threaded rod 13. A gear 14 is fixedly connected to the surface of the positive and negative threaded rod 13. A toothed plate 15 is provided on the right side of the gear 14. The left side of the toothed plate 15 meshes with the gear 14. An L-shaped plate 16 is fixedly connected to both the front and back of the toothed plate 15. The side of the L-shaped plate 16 away from the toothed plate 15 is slidably connected to the water tank 9. A threaded block 17 is threadedly connected to both the front and back sides of the surface of the positive and negative threaded rod 13. The bottom of the threaded block 17 is slidably connected to the water tank 9. A shaped plate 18 is fixedly connected to the top of the threaded block 17. The side of the shaped plate 18 away from the threaded block 17 is fixedly connected to the heat collection cover 7.

[0033] As a technical optimization of this utility model, the position of the heat collection cover 7 can be adjusted by setting the pipe adjustment mechanism 12, thereby increasing the heat collection uniformity of the heat collection cover 7.

[0034] refer to Figure 2 The front side of the top right side of the water tank 9 is connected to an exhaust pipe 19, which is used in conjunction with the water tank 9.

[0035] As a technical optimization of this utility model, the exhaust pipe 19 can discharge the air pressure inside the water tank 9, thus avoiding excessive air pressure inside the water tank 9.

[0036] refer to Figure 3 A bent rod 20 is fixedly connected to the bottom right side of the toothed plate 15. The bent rod 20 is used in conjunction with the toothed plate 15.

[0037] As a technical optimization of this utility model, the setting of the bent rod 20 makes it easier for the user to push the toothed plate 15, thus increasing the user's convenience.

[0038] refer to Figure 3Vertical grooves 21 are provided on the front and rear sides of the right side of the water tank 9, and the inner side of the L-shaped plate 16 is slidably connected to the inside of the vertical grooves 21.

Then, the heat inside the heat absorption tube 6 is discharged into the heat exhaust tube 8 through the input end of the heat exchanger 5. The heat inside the heat exhaust tube 8 is then transferred to the water tank 9, where it mixes with the water, achieving the effect of absorbing and reusing the heat. When it is necessary to adjust the position of the heat collection cover 7, the toothed plate 15 is pushed. The toothed plate 15 drives the gear 14 to rotate, the gear 14 drives the positive and negative threaded rods 13 to rotate, the positive and negative threaded rods 13 drive the thread block 17 to move outward, the thread block 17 drives the irregular plate 18 to move outward, and the irregular plate 18 drives the heat collection cover 7 to move outward, thus achieving the effect of adjusting the position of the heat collection cover 7.

[0043] In summary, this waste heat-utilizing thermoforming mold for automotive parts changes the traditional phenomenon of heat loss by using a heat absorption pipe 6 to absorb heat into the interior of the heat exhaust pipe 8, and then transfer the heat to the interior of the water tank 9. This prevents the heat from directly evaporating, thus avoiding energy loss and ensuring its environmental friendliness.
