Abstract: According to the structural characteristics of the storage boxshell in automobiles, the appearance, function, moulding, weld line of the product were analyzed. The design of injection mould was illustrated. The processing technology and assembly rationality of the injection moold should be fully considered to ensure the reliability, stability, and safety of the injection mould. Practices proved that the plastic parts’quality met customer’s needs.
