放大器殼蓋注塑模設(shè)計(jì)
摘要
在此次模具設(shè)計(jì)中,從塑件的成型工藝,模具成型結(jié)構(gòu)對(duì)塑件質(zhì)量的影響,澆注系統(tǒng),模具成型部分到模具的總裝等方面進(jìn)行了系統(tǒng)的分析,考慮。使在設(shè)計(jì)中盡可能的避免錯(cuò)誤的產(chǎn)生。介紹了放大器殼蓋注塑模設(shè)計(jì)時(shí)要注意的要點(diǎn),并較多的考慮了模具設(shè)計(jì)過程中的抽芯機(jī)構(gòu)設(shè)計(jì),模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。從控制制件尺寸精度出發(fā),對(duì)放大器殼蓋注塑模的各主要尺寸進(jìn)行了理論計(jì)算,以確定各工作零件的尺寸,從模具設(shè)計(jì)到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述,并應(yīng)用CAD進(jìn)行各重要零件的設(shè)計(jì)。

Summary
In this time molding tool design, model the craft from the piece of the molding tool models the influence of the structure upon a quantity of sprinkling to note the system, the molding tool models the part to molding tool total to pack etc. the aspect carried on the analysis of the system, consider.Make the creation that avoids the mistake possibly in the design.Want the advertent important point when introducing the enlarger hull cover note the mold design, and more consideration molding tool design process in of take out the 芯 organization design, molding tool structure of adjustment, replace the sex and molding tool cost easily.A size accuracy sets out from the control system, to the enlarger hull cover notes the mold of 塑 of each main size carried on the theories calculation, the size that to make sure each work spare parts, design zero partses to process the craft and assemble the craft...etc. to carry on to elaborate detailedly from the molding tool, and apply the CAD carries on each important spare parts of design.
