Abstract: Based on Pro/E software, an injection mould for the automobile rearview mirror crust of the automobile inner decoration was designed properly. According to symmetry and boundary mix approaches,the parting surface was assembled by a primary and a secondary parting surfaces using a slide block. A unique asymmetric core side-pulling mechanism was designed, which ensured the product being taken off from the injection mould. A cooling system of nearly circle shape with bi-directional water tubes in the same plane was also designed, which not only increased the cooling effect and the quality of the product,but also reduced the machining cost and the molding period.

Key words: automobile rearview mirror crust, parting surface, side core-drawing mechanism
