Design of injection mould for remote key shell of car
Considering the complex shape and high quality requirements of car key shells,it con-ducted process analysis and material selection for the moulded parts,and rationally designed the overall mould structure,layout,and gate position of the moulded parts.To ensure that the impact of high-pressure molten plastic on the miniature core would not affect the quality of the moulded parts,a core-pulling structure was adopted,and materials for miniature core and special require-ments for the cavity were verified and selected,and a process pillar gating was designed.For the undercut structure of the moulded parts,a secondary ejector structure was cleverly designed to al-low the undercut to be forcibly released.In addition,considering the interference between the min-iature core and the ejector pin ejection position,an anti-collision structure between the ejector pin and the miniature core was designed.
