Performance analysis and structure optimization of improved cubic mold carrier connector
摘要
Abstract
With the rapid development of the manufacturing industry and the continuous advancement of tech-nological innovation,the cubic rotary molds emerge as indispensable linchpins play a pivotal role in the assem-bly line ecosystem.To ensure their safety,reliability,and compliance while mitigating potential faults and damages necessitates,it is necessary to perform strength checks and fatigue life analyses on their carriers and connectors.This study delves into the optimization of threaded inserts,a critical component within cubic ro-tary molds,aiming to ameliorate stress concentration phenomena at primary threaded interfaces and enhance operational longevity.In order to meet the disassembly requirement of modern manufacturing,an improved cubic rotary mold was proposed.The center carrier of the new mold is made of lightweight aluminum alloy material,which greatly reduces the overall mass.While improving the manufacturing efficiency,it also pro-vides a feasible solution for the lightweight design of the device,and further promotes the development of the mold manufacturing field.Building upon the backdrop of the manufacturing landscape,characterized by its dy-namic progression and relentless pursuit of innovation,this research endeavors to elucidate the nuanced inter-play between design parameters and performance metrics within cubic rotary molds.Specifically,the study fo-cuses on the threaded inserts,crucial for maintaining structural integrity and operational efficiency.Through meticulous static analysis and the utilization of the Central Composite response surface experimental design method,the comprehensive impact of parameters such as the bottom width,height,and angle of external thread teeth on the maximum deformation and maximum equivalent stress of the threaded inserts is systemati-cally explored.The findings from this investigation contribute significantly to the advancement of cubic rotary mold design and optimization strategies.By deriving optimal solutions tailored to specific operational condi-tions,this research not only enhances the understanding of stress distribution phenomena within threaded in-serts but also provides practical insights for enhancing the operational lifespan and efficiency of cubic rotary molds in manufacturing environments.This research underscores the importance of integrating advanced ana-lytical methodologies with practical experimentation to address the evolving challenges within the manufactur-ing landscape and pave the way for enhanced productivity and product quality.The results show that,on the basis of the strength and fatigue life meet the design requirements,the deformation of the threaded sleeve structure is reduced by 3.1%,the equivalent stress is reduced by 3.1%,the life is increased by 20.6%,and the optimization design efficiency is improved,which also provides a theoretical reference for improving the structure of other die connectors.关键词
