摘  要
   
　　　實(shí)訓(xùn)設(shè)計(jì)的目的，是使學(xué)生用所學(xué)各科理論和知識(shí)和技能進(jìn)行的一次綜合性的應(yīng)用。本說(shuō)明書敘述的是窗簾環(huán)滾輪注射模的設(shè)計(jì)。通過(guò)對(duì)窗簾環(huán)滾輪的工藝分析，設(shè)計(jì)了一套一模三塑件的塑料模具。
　　　本次設(shè)計(jì)主要是通過(guò)對(duì)塑件的形狀、尺寸及其精度的要求來(lái)進(jìn)行注射成型工藝的可行性分析。塑件的成型工藝性主要包括塑件的壁厚，斜度和圓角以及是否有抽芯機(jī)構(gòu)。通過(guò)以上的分析來(lái)確定模具分型面、型腔數(shù)目、澆口形式、位置大?。黄渲凶钪匾氖谴_定型芯和型腔的結(jié)構(gòu)，例如是采用整體式還是鑲拼式，以及它們的定位和固緊方式。此外還分析了模具受力，脫模機(jī)構(gòu)的設(shè)計(jì)，合模導(dǎo)向機(jī)構(gòu)的設(shè)計(jì)，冷卻系統(tǒng)的設(shè)計(jì)等。最后繪制完整的模具裝配總圖和主要的模具零件圖及編制成型零部件的制造加工工藝過(guò)程路線。全書文字簡(jiǎn)明，圖表、數(shù)據(jù)翔實(shí)，所設(shè)計(jì)的模具結(jié)構(gòu)簡(jiǎn)單緊湊、動(dòng)作平穩(wěn)可靠、制造成本低，具有一定的可操作性。

　　　　Abstract
　　　　
　　　The purpose of training design: To make students apply comprehensively all sorts of theoretical knowledge and skill or technique acquired in the college to practice. The direction to be described is the Curtain ring roller. A set of mould with one model and three cavities has been designed through the correct analysis of the technology of the Curtain ring roller in the training design.
　　　This design primarily possesses to piece viability assessment for request for of shape, size and its accuracy coming proceeding injecting type craft. the piece the wall for of type craft primarily including the  piece is thick, slope and circle angle and whether to have core-pulling or not mechanism. Pass the above analysis to come the certain molding tool cent the type the surface, type  the number, gate the form, place the size; The among them and most important is a certain type core and the construction of the type, for example adopt the whole the type of type still, and their fixed position and tight way of .In addition and still analyzed the molding tool to suffer force, mold that design that the design of the pattern draw mechanism, match the design etc. to lead to the mechanism, cooling system. Finally draw the production that complete molding tool assemble the general drawing sum the soil and establishment of principal molding tool parts type zero the parts process the craft process route. The script in the direction is concise and the chart and data is full and accurate. The construction of the mould is simple and impact, the movement can be smooth and reliable, and the cost of manufacture is law. It is feasible to produce by using the mould.
　　　
Key words：the Curtain ring roller；injection mould；one model and three cavities.
