Abstract

The invention discloses a forming method of an automobile rear door triangular window covered edge. The method involves an injection mold internally provided with an inner framework mounting groove and a velvet strip mounting groove. The forming method comprises the following steps that (1) an inner framework and a velvet strip are preformed; 2) the inner framework is put into the inner frameworkmounting groove, the velvet strip is put into the velvet strip mounting groove, the injection mold is started to form an elastic body, and the injection mold is opened to obtain a semi-finished triangular window covered edge; 3) the semi-finished triangular window covered edge is ironed for 0.5-2 minutes through hot steam, and 4) the ironed semi-finished triangular window covered edge is blown through air flow until the velvet strip is dried to obtain the finished triangular window covered edge. According to the method, the problem that the velvet strip cannot be attached to the elastic body in a fitting manner is solved, and the triangular window covered edge with high quality is obtained.
