某深筒骨架形零件采用传统环形浇口设计的压铸模具,在实际生产中验证了其不足。本文通过对原有模具结构及金属液在充填过程中金属流态的分析,进一步确定了浇注系统的开设方式,并重新优化了模具设计方案,提高了零件的良品率。 A deep-tube skeleton-shaped parts of the traditional ring gate design of the die-casting mold, in the actual production of its deficiencies. Based on the analysis of the metal structure of the original mold structure and molten metal in the process of filling, this paper further determines the opening mode of the casting system and re-optimizes the mold design scheme to improve the yield of parts.
