Abstract

The invention provides a die structure and a die pressing method. The die structure comprises an upper die and a lower die which are oppositely arranged, a vacuum pump and vacuum tanks, wherein a forming cavity used for containing a to-be-formed part is formed between the upper die and the lower die, the vacuum pump is used for exhausting gas in the to-be-formed part, and the vacuum tanks are arranged inside the upper die and the lower die, one ends of the vacuum tanks are connected with the forming cavity, and the other ends of the vacuum tanks are connected with the vacuum pump. According tothe solution, by arranging the vacuum pump used for exhausting the gas in the to-be-formed part, the effect of exhausting VOC substances and smells of the part in a vehicle can be achieved at the same time in the forming process, the exhausting efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts processing and manufacturing, in particular to a mold structure and a molding method. Background technique [0002] Due to the needs of environmental protection and human health, the air quality inside the car has attracted increasing attention. Volatile organic compounds (VOC) in the car are the main source of air pollution in the car. The interior materials of automobiles include leather, fabric, rubber, plastic and other single materials or laminated composite materials, such as seat fabrics and pads, instrument panels, floor coverings, car interior panels, roof linings, etc., which are processed Additives, flame retardants, paints and coating materials used in the manufacturing process will volatilize VOC substances and odors during use. Excluding VOC substances and odors from parts is an important way to improve the air quality in the car. Contents of the invention [0003] Embodiments ...
