探測器后蓋模具設(shè)計(jì)及其型腔仿真加工
摘要: 本課題來源于鹽城科城電子有限公司，任務(wù)是探測器后蓋模具設(shè)計(jì)。針對探測器制品表面光滑度要高問題, 分析了探測器制品的工藝特性, 設(shè)計(jì)潛伏式澆口。通過制品質(zhì)量計(jì)算選擇了注塑機(jī)（SZ-100/60型）, 并且通過對零件的工藝分析確定型腔數(shù)量、選揮分型面、設(shè)計(jì)型芯和型腔，由于設(shè)計(jì)的零件屬于中小型所以采用了一模二腔的注塑形式。本模具選用的是標(biāo)準(zhǔn)的模架，并對動(dòng)、定模之間的導(dǎo)向和定位、工件推出機(jī)構(gòu)、澆注系統(tǒng)的總體布置方案、墊塊的尺寸、推出導(dǎo)向機(jī)構(gòu)、復(fù)位機(jī)構(gòu)進(jìn)行了設(shè)計(jì)，并且對組成模具型腔的各個(gè)部分進(jìn)行了計(jì)算，對所選的注塑機(jī)的各個(gè)參數(shù)進(jìn)行了校核。模具推出機(jī)構(gòu)采用的是頂桿推出 ，根據(jù)制品形狀對頂桿進(jìn)行了特殊設(shè)計(jì)。制品形狀的特殊性在加工方面采用了電脈沖加工。本模具結(jié)構(gòu)緊湊, 工作可靠, 成型工件滿足質(zhì)量要求，較好地實(shí)現(xiàn)了設(shè)計(jì)要求。

The Mold design of backsheell of detector and the processing simulation of the cavity
Abstract：The subjects come from the Yancheng City Branch Electronics Co., Ltd，Backshell detector Mold Design . To improveNote pieces detectorSurface quality and processing efficiency ，Reduce processing costs，Note against detector surface to a high degree of smoothness problem ，Note analysis of the detector characteristics of the technology，Latent-gate design。Through quality productsCalculation chose injection molding machine（SZ-100/60Types）, And parts of the Process AnalysisDetermine the number of cavity, Play election-surfaces Design-core and cavity . Because I want to belong to the design of partsTherefore, the use of a two-cavity injection form . The die is the choiceStandard moldbase , Also dynamic, Modeling between the orientation and positioning , Workpiece Launch, Gating system the overall layout program , Pad size, Launched oriented institutions, Reduction and the design agencies , And the mold cavity composed of the various parts of the calculation , Injection of the selected machines in all parameters of the Check . Die Launch is the launch mandril, According to shape products to push for a special design . The special shape products processing used electrical pulse processing. The compact structure Die, Reliable, Forming workpiece meet quality requirements , Achieve better design requirements.
