中文摘要

我設(shè)計(jì)的模具主要是生產(chǎn)Φ25環(huán)聚氨的化學(xué)填料。Φ25環(huán)聚氨的生產(chǎn)材質(zhì)為不銹鋼，采用沖壓加工工藝，因此需要設(shè)計(jì)一套沖壓模具。由于模具所要加工的零件為化工填料，它的特點(diǎn)是產(chǎn)品尺寸小、結(jié)構(gòu)簡(jiǎn)單、對(duì)精度沒有什么要求、沒有公差配合要求等。因此設(shè)計(jì)要求比較簡(jiǎn)單，與實(shí)際情況充分結(jié)合；達(dá)到既簡(jiǎn)單合理，而且又有較好的經(jīng)濟(jì)效益的目的。模具的設(shè)計(jì)要求根據(jù)沖件的具體形狀合理的簡(jiǎn)化模具結(jié)構(gòu)。以期達(dá)到易加工、成本低、效率高、壽命長等綜合性能最佳的效果。

Title    Press  mould  and  injecting  mould  design

Abstract
Many mothen to reduce working procedure reasonably and to improve the compound degree of stamping die were described  by enumerating many kind of special structure of die.In the condition of assuring reliability and life of die,much more economic benefits could be obtained by improving the compound degree off die. By summarizing the practical  experiences,it could provide some references for the  design and manufacturing of the same part.
Thourgh  analyzing the characteristics of open  mold, eject mold and close mold, design mould  structure.the algorithm of simulation  mould moving  was put forward.The  At last,the original systerm of injection mould moving was realized in CAXA 3D parametric feature modeling software.  

Keywords   stamping die       compoud die     extrusion trimming
