Abstract
The design process of the automobile combination instrument cover single-cavity injection mould is mainly introduced in this paper. The shape, structure of the plastic part and the performance of using plastic are firstly analyzed, and the injection machine is selected with some of its parameters being checking, and design the appearance.structure with the UG three dimensional entity designing, determining the design proposal. Then the overall structure of the injection mould is designed, including the pouring system design, the formation part and its components design, the overflow and bleed system design, the cooling system of temperature adjusted system design, demould mechanism design. The demould mechanism design is emphatically introduced in the paper, which accomplish the plastic part isolating from the mould, the side-extracting core mechanism design and the ejecting mechanism design being two emphasizes.
