Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior trim panel processing, in particular to a hot pressing and shaping device for automobile interior trim panel processing. Background Art

[0002] With the rapid development of the automobile industry, lightweighting has become a trend in automobile development. Automobile lightweighting means reducing the curb weight of the automobile as much as possible while ensuring the strength and safety performance of the automobile, thereby improving the power of the automobile, reducing fuel consumption, and reducing exhaust pollution. The large-scale application of high-strength plastics is an option to achieve automobile lightweighting. With the increasing national energy-saving and emission reduction indicators for automobiles, the large-scale application and production of automobile plastic parts has also become an important research direction for automobile companies, especially for automobile interior panels, which are often made of high-strength thermoplastic composite plastic materials through hot pressing;

[0003] At present, the hot pressing and shaping device for processing automobile interior panels usually places the blank plate to be hot pressed and shaped on the top of the lower mold, heats the blank plate to be hot pressed and shaped by a heater, and performs compression molding after heating. During the heating process, the heater will emit a high amount of heat, causing the temperature of the surface of the lower mold to rise. If the user accidentally touches the lower mold, it will cause burns, which poses a great safety hazard. Therefore, we provide a hot pressing and shaping device for processing automobile interior panels. Utility Model Content

[0031] Specifically: before the automobile interior trim panel needs to be hot-pressed and shaped, the user places the blank plate to be hot-pressed and shaped on the top of the lower mold 8. After the placement is completed, the user starts the first drive motor 5 to work, and drives the threaded rod 4 to rotate clockwise through the first drive motor 5, drives the threaded sleeve 19 to move to the right through the threaded rod 4, drives the fixed plate 10 to move to the right through the threaded sleeve 19, drives the heater 9 to move to the right through the fixed plate 10, drives the lower mold 8 to move to the right through the heater 9, and moves the blank plate to be hot-pressed and shaped into the inner cavity of the bracket 1 through the lower mold 8.
