模具畢業(yè)設(shè)計--病床背板絲桿的模具設(shè)計

1、病床背板絲桿的模具設(shè)計摘要隨著時代的發(fā)展，模具設(shè)計及制造的發(fā)展也越來越“現(xiàn)代化”，越來越“高效益”。當(dāng)今，模具已經(jīng)成為塑料制品生產(chǎn)與更新不可或缺的基礎(chǔ)和前提，往往在注射模具的設(shè)計技術(shù)與制造水平上，?？蓸酥疽粋€國家工業(yè)化的發(fā)展程度。本次設(shè)計對病床背板絲桿進行注塑模具設(shè)計。對該塑件進行工藝性分析與工藝計算并確定注射機型號，確定合理的注塑工藝方案。通過大量的查閱文獻資料和實驗研究，理論和實踐結(jié)合，進行比較分析，通過查閱圖書館和網(wǎng)上的資料，確定
