[0001] The utility model relates to the technical field of hot pressing molding, in particular to a hot pressing device for a polyester sound-absorbing board. Background Art

[0002] Polyester fiber acoustic panels are a sound-absorbing decorative material made from polyester fibers through heat-pressing. During processing, the polyester fiber panels typically require heat pressing. When the polyester fiber panels are heated, the sides of the heating panel contact the inner wall of the container. Heat from the heating panel transfers to the container, resulting in uneven temperature on the heating panel and affecting the panel's heat-pressing effectiveness.

[0003] Therefore, Chinese Patent Publication No. CN 214872138 U proposes a polyester fiber sound-absorbing panel hot-pressing molding device, comprising a vertical plate, the upper end of which is fixedly connected to the rear end of an upper plate, the lower surface of which is connected to the upper end of a cylinder, the lower end of which is mounted with an electric heating plate, the lower end of which is fixedly connected to the rear end of a lower plate, and a receiving box fixed to the front end of the lower plate. The upper surface of the receiving box is provided with a groove adapted to fit the electric heating plate, within which a polyester fiber sound-absorbing panel is positioned. The upper portion of the left side of the receiving box is provided with a first elongated hole communicating with the receiving box groove.
