By designing Sai Bao automobile combinative instrument cover, this paper firstly introduces the choosing basis and significance of the subject, its home and abroad studying station and main studying contents with its adopting methods, design’s difficulties and solutions, briefly expounding its development prospects. Next, the whole design process of injection mould is introduced, that is, analysis plastic part, choose injection machine with some of its parameters being checked so as to satisfy design demands, then the injection mould overall design is introduced, such as the forming parts and components design forming plastic part’s geometry and dimension, the pouring systems design transporting melt plastics, the overflow and bleed system design discharging air which affects plastic part’s precision, the temperature adjusted system design only designing the cooling system here, demould mechanism design isolating and retrieving already molding part, and mould-frame design. UG drawing software is utilized to accomplish the forming parts and components design, in addition helix-pillar and moving-core are used to form and extract the side-hole, helix-slider is used to extract the pock-hole’s block ears. Experiences are expounded in the end of the paper. Keywords：Injection mould；Cooling system；Pouring system Side-extracting core mechanism；Helix-slider
