Description

Technical Field

[0001] This utility model belongs to the field of hot pressing molding technology, specifically relating to a hot pressing molding device for automotive carpets. Background Technology

[0002] In the automotive interior parts manufacturing industry, automotive carpets are an important component, and their molding quality directly affects the aesthetics, comfort, and sound insulation of the vehicle interior. Currently, automotive carpets are mostly produced using a thermoforming process, which involves applying high temperature and pressure to the carpet blank to shape it according to a pre-set mold.

[0003] Traditional carpet making involves heating and baking the raw carpet, then pressing the softened carpet into a molding die. During the process, the carpet blank is manually placed on the lower die, and then the upper die presses down in conjunction with a heating element to complete the hot-pressing operation. This method has the following drawbacks:

[0004] First, the loading and unloading operations are inefficient. Because the lower mold is fixed at the hot pressing station, operators need to place the blanks and pick up the finished products near the hot pressing mechanism. This not only limits the operating space but also makes them susceptible to high temperatures, increasing the difficulty of operation and safety hazards, while also hindering the improvement of production cycle.

[0005] Secondly, the sealing and temperature controllability of the hot pressing environment are inadequate. Traditional equipment often uses open or semi-open hot pressing zones, requiring the carpet blank to be transferred between the oven and the forming mold. This leads to heat loss, uneven temperature distribution of the blank during hot pressing, and difficulty in precisely controlling the hot pressing temperature. This not only affects the forming effect of the carpet blank but also increases energy consumption and reduces production efficiency.

[0006] Secondly, the temperature control accuracy is limited. Although some devices are equipped with heating components, they lack a real-time monitoring and feedback mechanism for mold temperature, making it impossible to accurately control temperature changes during the hot pressing process. This makes it difficult to adapt to the different hot pressing temperature requirements of carpet blanks of different materials and thicknesses, thus affecting the stability of molding quality.

The movable mold 2 is driven by a translation drive mechanism to move between the loading platform 3 and the base 1. A pressing mold 6 is provided above the base 1, and a mounting plate 7 is provided above the pressing mold 6. The mounting plate 7 is fixedly connected to the base 1 by several sliding rods 8. Sliding sleeves are provided on the sliding rods 8, and the sliding sleeves are fixedly connected to the pressing mold 6 respectively. Side plates 9 are provided around the movable mold 2, and all the side plates 9 form a hot pressing chamber 10. The movable mold 2 is located in the hot pressing chamber 10. The pressing mold 6 is driven by a downward pressing drive mechanism to extend into the hot pressing chamber 10 from the upper end of the hot pressing chamber 10. The downward pressing drive mechanism is mounted on the mounting plate 7. The temperature of the hot pressing chamber 10 is controlled by a heating device. The side plate 9 near the loading platform 3 is fixedly connected to the movable mold 2. The movable mold 2 moves to the loading platform 3, and the preheated blank is placed on the movable mold 2. The movable mold 2 then moves to the base 1. The pressing mold 6 descends to a certain height, forming a relatively sealed space in the hot pressing chamber 10. The heating device continuously heats the chamber, maintaining a constant temperature for a certain period of time. The pressing mold 6 descends to hot press the blank. Finally, the pressing mold 6 rises, and the movable mold 2 moves to the loading platform 3, where the molded automotive carpet is unloaded.

[0022] Furthermore, except for the side plate 9 which is fixedly connected to the movable mold 2, the other side plates 9 are driven to move by the cylinder 15. The lower end of the side plate 9 is fixedly connected to a sliding plate, which is mounted on the guide rail 17. After the movable mold 2 moves with the blank to the base 1, the pressing mold 6 descends above the movable mold 2. The other side plates 9 are then driven by the cylinder 15 to form a closed hot pressing chamber 10. After the temperature in the hot pressing chamber 10 stabilizes for a period of time, the pressing mold 6 continues to descend to hot press the blank.

[0023] Furthermore, the pressing drive mechanism includes a hydraulic cylinder 18 located on the mounting plate 7, and the output shaft of the hydraulic cylinder 18 is fixedly connected to the pressing mold 6.
