Productive technology of automobile rear shelf

Abstract

The invention relates to a productive technology of an automobile rear shelf, which comprises the following steps: (1) laying a glass fiber mat on a lower die and fixing the glass fiber mat and a reinforcing rib on an upper die; (2) evenly spraying polyurethane on the glass fiber mat on the lower die; (3) compressing the glass fiber and the reinforcing rib in a die to form semi-finished products;(4) taking the semi-finished products subject to compression moulding out of the die, and placing the semi-finished products on a cooling jig for carrying out cooling and moulding at normal temperature; (5) polishing the semi-finished products subject to cooling and moulding to smooth the surfaces of the semi-finished products; (6) evenly spraying glue on the two sides of the polished semi-finished products; (7) binding linings on the two sides of the semi-finished products on which glue is sprayed; (8) punching fiber bundles of the glass fiber mat exposed at the edge of the semi-finished products subject to lining binding; (9) installing pull ropes on the punched semi-finished products to obtain the finished products; and (10) inspecting and carrying out vanning. The productive technology of the invention can save manufacturing cost and has the advantages of environmental protection and no pollution.

Description

technical field [0001] The invention relates to a production process of a car rear shelf, in particular to a production process of a rear shelf installed at the rear of a car and used for placing articles, and belongs to the technical field of car interior parts.
