新科MP4上蓋模具設(shè)計及型腔仿真加工
摘要：本課題是關(guān)于MP4上蓋模具設(shè)計及型腔仿真加工。通過運(yùn)用模具設(shè)計基礎(chǔ)和PRO/E、AutoCAD等這些課程的知識去做一次模具設(shè)計的實踐，并在這次實踐中鍛煉自己用理論知識來解決實際問題的能力。
本次模具設(shè)計主要是對MP4上蓋注射成型模的結(jié)構(gòu)設(shè)計和模具加工制造。前者包括分型面、型腔布置、澆注系統(tǒng)、排氣系統(tǒng)、加熱冷卻系統(tǒng)、抽芯機(jī)構(gòu)、頂出機(jī)構(gòu)、脫模機(jī)構(gòu)以及主要零部件的設(shè)計。后者運(yùn)用PRO/E進(jìn)行三維造型設(shè)計并對注塑模模具進(jìn)行裝配，對MP4上蓋模具定模板型腔的加工工藝進(jìn)行了分析，并利用MASTERCAM軟件進(jìn)行了仿真加工，其切削過程直觀，切削參數(shù)得以體現(xiàn)，不合理的參數(shù)可以改進(jìn)，能最大限度地降低能源和材料消耗，提高加工效率。經(jīng)生產(chǎn)驗證，該模具結(jié)構(gòu)設(shè)計巧妙、操作方面、使用壽命長、塑件達(dá)到技術(shù)要求。

Tne design of the roof of new MP4 mould And
The simulation processing of the mold cavity
Abstract ：This topic is to design the above of MP4 mold design and process simulation process of the cavity. Through use the foundation of design and Proe, AutoCAD such as the knowledge to do the work of these courses a mold design practice, and practice in this exercise with their theoretical knowledge to solve practical problems.
The mold design mainly cover the structure design mould assist designing for manufacturing, and the working process of the injection mould of the roof of the MP4 were introduced. The former involve parting plane, cavity layout, old systems, heating cooling systems, the core pulling mechanism structure, prop up the organization, drawing patterns and the design process of the main work pieces. The later use Proe to construct carries on the three dimensional modeling and to assemble the injection mould. The processing craft of the cavity of fixed plate of the base of the mp4 are analyzed, and the simulation process are carry out with the software of MasterCAM，which can observe the geometric figure of the process of cutting very visually, the machine parameters users setting have been fully reflected to improve the unreasonable parameters, to minimize consumption of energy and materials and to improve processing efficiency. The mould was proved to be a clever design by production practice , the mould could be operated easily , the service life of the mould was long or and the plastics parts produced by the mould could meet the technical requirement.
