摘　　要：通过对壳体零件的结构和成形性分析,重点对模具设计的主要环节进行了详细的分析与研究;分析设计了模具的分型面位置、浇注和排溢系统的结构以及推出机构,采用在侧面厚壁处多点浇口的结构形式;对模具的型芯、型腔做了具体的结构设计,采用型腔在定模、型芯在动模的普通两板式结构形式;并且型芯和型腔部分制作成活动镶件,便于修理、更换,模具结构简单、实用,完全满足模具的设计要求。By analyzing the structure and formability of shell parts,the main link of die design was analyzed and studied.The position of parting surface,the structure of pouring and overflow system and the pushing mechanism of the die were analyzed and designed.The structure form of multi-point gate at the thick side wall was adopted.And specific structural designs had been made for the core and cavity of the die,using a common two plate structure with the cavity in the fixed mold and the core in the moving die.The core and cavity parts were made into movable inserts for easy repair and replacement.The die structure was simple and practical,fully meeting the design requirements of the die.
