Abstract

The invention relates to a technology for producing a cover plate of a vehicle trunk, comprising the following steps of: flat-placing a planar blanket into a cutting mold, and cutting the planar blanket into a required shape; fixing the planar blanket on a fit mold, wherein the front face of the planar blanket faces downwards, spraying polyolefin glue on the back face of the planar blanket and the back face of a substrate, and applying the back face of the planar blanket onto the front face of the substrate, to obtain a crude product of the cover plate of the vehicle trunk; applying the front face of a cover plate material of the vehicle trunk onto the back face of the substrate in the crude product of the cover plate of the vehicle trunk, to obtain a semi-finished product of the cover plate of the vehicle trunk; and finally pressing the semi-finished product of the cover plate of the vehicle trunk in a pressing die, to form the cover plate of the vehicle trunk after pressing. The method of the invention has advantages of simple technology, fewer operation steps, no harmful substance generation in a production process, environmental protection and no pollution, reduces manufacturing cost, greatly raises vehicle disassembling precision requirement of the cover plate of the vehicle trunk, and raises sound insulation effect.

Description

technical field [0001] The invention relates to a production process of an automobile trunk cover, and the invention belongs to the technical field of automobile interior parts production. Background technique [0002] As a part of the interior parts of the car, the trunk cover is generally installed on the spare tire groove in the trunk to play the role of isolation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, light weight, and individualization, the interior parts of automobiles, like the appearance of automobiles, have become an important factor for people to choose and buy automobiles. Therefore, the requirements for automotive interior parts are getting higher and higher. [0003] In the prior art, the trunk cover of a car is generally made of a combination of surface blanket and base material and the edge of the surface blanket in the subsequent process. The previous process mainly has the follow...
