【正文】 定模仁冷卻水路的三維模型第十三章 Pro/E繪制三維零件第12章 安裝尺寸的校核本模具經(jīng)過理論計算以及結(jié)構(gòu)設(shè)計,確定了模具各個部分的尺寸,尤其是外形尺寸對能否裝到注射機(jī)上至關(guān)重要。本次設(shè)計的模具要求的模文在80攝氏度左右,本套模具屬于中小型模具,所以無需外加加熱裝置。為了保證側(cè)抽芯機(jī)構(gòu)連續(xù)的進(jìn)行,必須在抽芯完成后的終止位置進(jìn)行定位。 定?;瑝K定位機(jī)構(gòu)第九章 側(cè)向分型與抽芯機(jī)構(gòu)的計算第9章 側(cè)向分型與抽芯機(jī)構(gòu)的計算該塑件的側(cè)孔直徑為6mm,長度為14mm,抽芯距比較短,因此本次設(shè)計采用的是機(jī)動抽芯,利用注射機(jī)的開模力,通過傳動零件,將活動型抽芯出,采用斜導(dǎo)柱抽芯機(jī)構(gòu),側(cè)型芯與斜導(dǎo)柱組合,由抽芯板與斜導(dǎo)柱相連來完成外側(cè)抽芯動作。這也是本次設(shè)計的一個亮點。能夠?qū)崿F(xiàn)這樣運(yùn)動的機(jī)構(gòu)就叫做推出機(jī)構(gòu)。其上型芯孔與型芯采用H7/g6配合,與定距拉桿采用間隙配合。(4) 定?;瑝K壓板69x300,厚度73.用來固定定?;瑝K、導(dǎo)柱、導(dǎo)套,材料為T10A。由于塑件結(jié)構(gòu)的緣故,采用標(biāo)準(zhǔn)模架很難成型塑件,所以必須在標(biāo)準(zhǔn)模架上進(jìn)行改裝,以下是各個模具部件尺寸:(1) 定模座板 300x350,厚度25.定模座板常常用作模具與注射機(jī)連接處的板,通過壓板固定,材料為45鋼??紤]到塑件比較長,所以將凹模分為上中下三個,這樣便于表面加工以及冷卻水路的設(shè)計。(1) 確定注射時間:由Moldflow得到塑件注射所需。 分流道的體積(1)(2)(3)(1)(2),所以,在試模過程中,課適當(dāng)減少注射時間,以達(dá)到合理的剪切速率。(1) ,對于本套模具由于具有側(cè)向分與抽芯機(jī)構(gòu),所以初選36mm進(jìn)行計算校核。的SA1600/540型注射機(jī)。第一分型面將塑件主體脫出,由于塑件包緊在型芯上的面積比較大,在脫模過程中可能會損壞為脫模的側(cè)抽芯部分,造成塑件的損傷。第二章 模具結(jié)構(gòu)形式的確定 型腔數(shù)量的排布由于塑件有三個分型面,所以需要考慮模具開模時分型面打開的順序。該方案由斜導(dǎo)柱、滑塊、楔緊塊、壓板等零件構(gòu)成。第2章 模具結(jié)構(gòu)形式的確定方案一:采用斜頂機(jī)構(gòu)進(jìn)行分型,該機(jī)構(gòu)主要由導(dǎo)滑槽、定位銷、斜頂桿、滑塊等零件組裝而成。側(cè)向分型抽芯機(jī)構(gòu)主要分為兩種,一種是外抽,另一種是內(nèi)抽,而本塑件只需要外抽即可。關(guān)鍵詞 : 塑料模具設(shè)計,側(cè)向分型分析,CAD/CAE,塑料顧問,Pro/E IAbstractThe main task of this graduation design is the design of the injection mould for medical drip device. From the plastic parts of the shape and internal structure, need two times side parting and core pulling. The upper part of the side core pulling is forming the throttle valve, and the lower part of the side core pulling and forming the outer threaded portion. From the requirements of plastic parts of the size and the product, the injection mould need high precision, it is also a difficult point of the design. From the design point of view, the threedimensional design involved, especially the application of 3D design in the mold design, the main difficulty lies in the threedimensional mold gate location and type, form, and finally the establishment of 3D assembly realization.The advanced mould CAD/CAE technology is widely used in the design of the injection mould. For example, in the design uses the Pro/E sub module, which greatly simplifies the design of the mould cavity, improves the design efficiency. And the use of Plastic Advisor in the design process, a simple analysis of the plastic parts of the cavity and runner and other important parts, the feasibility of the mold has a guiding role to a certain extent. In the design stage, using the Pro/E optimized, and the 3D assembly, the last generation of 2D part drawing, so the optimization to reduce a lot of work late.Keywords: plastic mold design, lateral type analysis, CAD/CAE, Plastic Advisor, Pro/E.第一章 任務(wù)分析
