Description

Technical Field

[0001] The invention belongs to the technical field of automobile instrument panel covering molds, and in particular relates to a hot and cold pressing device for covering an automobile instrument panel. Background Art

[0002] The car dashboard is an important part of the car. The dashboard often needs to be integrated with air conditioning, audio, various electronic instruments and driving computers, so the dashboard needs to have sufficient rigidity. In addition, in order to reduce the damage to the occupants when an external accidental collision occurs, the dashboard needs to have excellent energy absorption characteristics. These are determined by the structural characteristics of the dashboard. In recent years, with the development of our automobile industry and the continuous improvement of people's living standards, consumers have paid attention to the safety and environmental protection of cars while also putting forward higher requirements for the comfort of car interior decoration, especially for the dashboard part that can be intuitively felt by the driver and passengers. For a good dashboard, it is not only necessary to design a beautiful and novel appearance, but also a comfortable touch, so the dashboard needs to be wrapped. There are two main structural forms of traditional instrument panel covering equipment: the first is that the pressing and glue activation processes are separated. The instrument panel that has been sprayed with glue needs to be heated before pressing. This heating process requires a separate set of equipment, and the heating method is mostly hot air heating. The process is cumbersome, the working hours are long, and the product quality is difficult to guarantee; the other is a hot and cold mold integrated form, which can be used for both heating glue activation and cooling glue bonding.
