Abstract

The invention discloses a hot-pressing air-blowing forming method of a decoration member of automobile trunk. The method is characterized in that a first layer of wood powder plate is heated in a baking oven to a high elastic state for keeping constant temperature, the holes are made on the first layer of the wood powder plate, then a second layer of wood powder plate which is heated to the high elastic state is laid on the first layer wood powder plate, non-woven fabrics are respectively laid on a lower die and an upper die of a relative die of the first layer wood powder plate and the second layer wood powder plate, the matched die stitches the first layer wood powder plate, the second layer wood powder plate and two layers of non-woven fabrics, high pressure gas is employed for carrying out high pressure gas blowing between the first layer wood powder plate and the second layer wood powder plate, a honeycomb structure is formed by bonding the first layer wood powder plate, the second layer wood powder plate and two layers of non-woven fabrics, then processes of keeping pressure, cooling and moulding are performed. The invention has the advantages of comprehensively raising the integral performance of the product, raising surface quality of the product and raising the product quality.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile trunk trim, in particular to a hot-press blow molding method for an automobile trunk trim. Background technique [0002] There are two main production processes of traditional car trunk trims: one is to use wood powder board + non-woven fabric as raw materials, which are cut into shape and then bonded to form a finished product. The advantage of this product is a flat structure. The structure is simple, the cost is low, and the disadvantage is that the material performance is poor and cannot meet the basic requirements of the vehicle (such as strength, hardness, water resistance, compression resistance, etc.); the odor cannot meet the requirements (formaldehyde, etc. exceed the standard); the surface quality of the parts is poor , not aesthetically pleasing. The other is to use phenolic resin felt + non-woven fabric as raw materials, which are formed by hot pressing and assembled to for...
